Operations Research and Management Science). He frequently

invited as keynote speakers and visiting professor in several

universities. His main expertise is in Data Mining, Optimization and

Metaheuristics, Operations Research, Project Management.

Summary Speech:

Manufacturers are generating vast amounts of data through their

process. They can build a system to uncover critical information to

enable smart operations and drive the business. It can be applied at

shop floor, supply chain or procurement. Advanced analytics helps us

identify patterns and dependencies within our systems. By doing that

we can make right decisions or optimize the whole process.

Big data analytics can improve manufacturing process in some stages.

For example in Predictive maintenance. Knowing when a part is

going to break reduces downtime and waste. By analyzing factors that

drive the wear of our devices, we gain transparency on the real

lifetime of our products. Then, in Product optimization.

Understanding what drives the quality of our production avoids waste

and improves the overall equipment effectiveness (OEE). Advanced

analytics identifies parameters that cause variable levels of quality or

efficiency. Of course there are still many more applications in

manufacturing system.

Abstract The combination of tungsten trioxide(WO3) with titanium oxide (TiO2) as a

composite catalyst has several advantages than TiO2 one. This composite

particle can be activated under visible light irradiation and has better

photocatalytic efficiency than their pure substances. The purpose of this study

are to synthesize composite WO3/TiO2 and to investigate the detail effect of

sodium tungstate dihydrate (Na2WO4.2H2O, as WO3 source) and TiO2 anatase

(as TiO2 source) compositions on particles morphology, shape and structure ,

crystallinity, and photocatalytic performances. To synthesize WO3/TiO2

particle, a facile sol-gel method was used. Experimental results showed that

composition of WO3/TiO2 (1:3) had significant effect on the photocatalytic

performance , however deviation of this amount had improved catalyst

performance slightly. A confirmation to get the basic reason of this catalytic

increase has been done by investigating the effect of catalyst dosage on 10

mg/L of methylene blue (MB). The adsorption kinetics of WO3/TiO2 particles

toward MB degradation is evaluated by Langmuir isotherm adsorption model.

Photodegradation test showed that the concentration (Ct /Co) of 180 ml of MB

decreases rapidly up to 88 % with 180 mg WO3/TiO2 (1:3) for 120 min.

irradiation. These results initiate new information regarding varied properties

of WO3/TiO2 composite for organic pollutant removal.

Abstract The robotics system that is increasingly developing until now becomes an

opportunity for every human being to use it in various activities such as

automatic control systems in land vehicles that can be referred to as

Ground Vehicle. Ground Vehicle has several categories based on

autonomous systems provided named teleoperated, semi-autonomous,

platform-centric and network-centric. In this study the prototype Ground

Vehicle system to be used is a semi-autonomous type using the fuzzy logic

method as its support system. Fuzzy logic has an input variable consisting

of distance between the prototype and obstacle then the output variable is

the action of Ground Vehicle on the safe distance from the obstacle. The

formed fuzzy logic system has been integrated with the robotdyn UNO

microcontroller device as a Ground Vehicle prototype control center. The

test results showed that the prototype motion was in accordance with the

provisions of rule base fuzzy logic and predetermined setpoints that is 10

cm - 15 cm from the obstacle and the results of semi-autonomous system

movement that has been applied in ground vehicle prototype.

Keywords: Fuzzy Logic, Ground Vehicle, Semi-Autonomous.

Abstract Heart beat measurement system is an important issue to monitor the health

condition of human being. In normal resting, heart rate will be beaten

between 60 to 100 beats per minute (bpm) depending on the age and

physical condition. Through the heart rate monitoring, several severe

diseases can be discovered as preventive action of mortality, for instance

heart failure. The work within this study presents a developed heart beat

monitoring (HBM) using an optical proximity sensor to measure heart

rate. It involves both the measuring on fingertip and wrist for comparison.

The proposed HBM detects the blood flow through the index finger, while

the wrist measurement employ a pedometer in a smart watch of Xiomi Mi

Band 3. A HBM consists of optical sensor with a light source and detector,

microcontroller module of NodeMCU ESP8266, and an organic light

emitting diode (OLED) display. The experimental tests measure the heart

beat with two conditions, such as no activity and after activity states; and

with three different ages. The results indicate that proposed HBM is

suitable for monitoring heart rate and obtained data is possible to provide

via mobile and internet applications.

Abstract

Utilization of biomass as an energy source is very important, especially

by-products from forestry, plantations and livestock. Biomass as fuel still

has many disadvantages, both in terms of water content, calories and

weight. To overcome this, a thermochemical process is needed, namely

Torrefaction. Torefaction is a heating process between 200-325 0C with

minimal oxygen conditions. This process is being widely used to improve

the properties of biomass as fuel and reduce the weaknesses of biomass,

such as low heating and energy density, high inertia, low combustion

efficiency, and high milling energy. In this study of palm kernel shell

torrefaction was carried out from 0.5 cm sieve with three variations in

temperature and residence time follows 250 0C - 300 0C and 20-40

minutes then analyzed ultimate. The high heating value is predicted using

ultime data calculated by the equation of Chang Dong and Azevedo, Fried

and Ozyuguran then used to determine energy yield. The optimum process

for torrefaction of palm kernel shell according to calorific value and

energy yield is 275 0C with residence time 20 minutes.

Abstract One of the factors that caused the wound dressing to be wet is water seep

which enters through wound dressing pores. This causes the dressing to

be wet and it must be replaced frequently. Therefore, one of wound

dressing called Hypafix is coated with beeswax-chitosan mixture to obtain

a waterproof ability. The purpose of this study is to determine the effect of

concentrations of beeswax and chitosan solutions as a superhydrophobic

coating material on Hypafix and analyze the characteristics of

waterproof. There are two models of research, beeswax concentration (0,

0.25, 0.5, 2, 2.5%w/v) with constant concentration of chitosan 0.5%w/v,

and chitosan concentration (0, 0.25, 0.5, 2, 2.5%w/v) with constant

concentration of beeswax 0.5%w/v. The contact angle (θ), hysteresis,

morphology of film, and functional group analysis were characterized.

The results showed that the contact angle was significantly increased with

increasing beeswax and chitosan concentrations, but decreased at a

concentration of 3%wt/v. The lowest hysteresis of sample was successfully

obtained at 1.3 degree with θ~151.2 degree using beeswax/chitosan

concentration of (2.5 : 0.5) %wt/v. Scanning Electron Microscope (SEM)

showed that the film covered the gauze fibers, hence the surface was

rougher and also increased contact angle as explained in Cassie-Baxter

Theory. Furthermore, FTIR indicated that the layers formed by both

beeswax and chitosan compounds, while they contributed to the Hypafix

surface superhydrophobicity in optimum concentration.

Study on The Effect MnO2-deposited Carbon

Nanofiber Mat and Their Electrochemical

Performance

Abstract Electric energy storage technology has evolved along with the increasing

of the human need for portable electronic devices and the development of

electric-powered vehicles, one of which is capacitors. Material that is

often used for capacitors is activated carbon and requires a binder, but

the binder reduces the performance of activated carbon as an electrode.

An alternative material that can be used as a substitute for activated

carbon is carbon black. One type of carbon black is acetylene black (AB).

AB has been widely used as an additive for conductive additives in the

electrode preparation process because it has a large and low-density

specific area. Poly (vinyl alcohol) (PVA) has physical properties of

hydrophilic and semi-crystalline polymers. Some of the advantages of

PVA are having good thermal stability, chemical resistance, good physical

property, and excellent biocompatibility. Based on this, PVA is very

interesting to be developed as an electroactive composite matrix

containing acetylene black. PVA/AB composite carbon nanofiber is made

using electrospinning techniques. Further development of carbon

nanofiber as an electrode material needs modification with the addition of

MnO2 through immersion techniques. The results of the SEM and XRD test

showed that MnO2 was deposited on the carbon nanofiber surface area.

The effect of adding MnO2 can increase the capacitance of the PVA/AB

composite CNF.

Abstract Coal is one of the energy sources that widely used for electricity.

Nonetheless, the high demand for coal is not comparable with the

remaining coal in the world, so it is necessary to make a study to reduce

the consumption rate of coal. Increase the efficiency of the tangentially

fired boiler with improvement in the burner is one of the right options. In

some case, because of uneven distribution of coal type, blended of mixing

coal of higher and lower rank coal is necessary. This condition will affect

the combustion behavior in the boiler, also emission production. This

research will study the effect of yaw angle modification to combustion

behavior and emission analysis in the tangentially-fired boiler with the

condition of fuel 30% MRC and 70% LRC. Computational fluid dynamics

has been used in this study with validation. The yaw angle diverse from

+5º, 0º, -5º, -10º, and -15º. The results show that the wider yaw angle

increases the temperature deviation and NOx concentration. Coal burner

with -5º has the least temperature deviation and the lowest NOx emission

which has 83,07 ppm of NOx, then -5º yaw angle is chosen.

Abstract Crossflow wind turbines have good ability to capture wind so it is very

suitable to be developed in areas with low wind speeds. The efficiency of

a crossflow wind turbine is taken from two sides so its turbine have high

efficiency. The first side is when the wind enters the turbine pushes the

front face of the blade and the second side is when leaving the turbine, the

wind pushes the rear face of the blade. In designing a crossflow wind

turbine, design parameters can affect the height or low performance of the

turbine. The main objective of this study was to determine the flow

characteristics and performance of crossflow wind turbines. The turbine

is designed with a diameter ratio of 0.5 and blade slope of 90˚. The number

of blades used as a test is 18 blades. Turbines was simulated with at 3 m/s

of wind speed on TSR 0.1 - 0.5. The results obtained from this study are

wind flow visualization and crossflow wind turbine performance

parameters. The crossflow wind turbine performance parameters are

power coefficient, moment coefficient and tip speed ratio.

Abstract In connection with the high demand for energy in remote and rural areas,

one way to meet these needs is to make micro hydro-based electricity.

Microhydro electrical energy is very suitable for use in rural areas

because the area is usually found in many sources of waterfalls that can

be used as a source of micro-hydropower without causing environmental

damage. In this case, the author made a prototype of micro-hydropower

to be able to analyze the effect of rotation of the turbine with the voltage

generated, before it will be implemented. The faster the generator rotates,

the greater the voltage caused by the rotor cutting the line magnet force

on the stator coil so that the resulting voltage will be faster too. In testing

the maximum 6V results in the 1200 RPM turbine rotation, it can be said

that the results obtained are only half of the generator's work, due to the

water pressure that does not affect the turbine rotational motion.

Abstract Cement Industry in Indonesia has grown significantly every year.

Limestone is one of the raw cement substitution material which has rapidly

grown. Cement production process released carbon dioxide (CO2) which

resulted in global warming. As an alternative material substitution, fly ash

(FA) and bottom ash (BA) as the remained coal were generally used for

cement production. PLTU Kaltim Teluk, one of steam power plant which

located in Balikpapan, East Kalimantan, produced 150 tons of FA in a

day. However, FA and BA were laid out in the landfill and had not

managed well. Actually, FA and BA had potential material as a

substitution of cement in the paving block ingredients. Adding an alkaline

activation which consist of sodium silicate (Na2SiO3) and sodium

hydroxide (NaOH), could be increased the compressive strength,

especially for paste using 100% FA. The property of FA was characterized

by Scanning Electron Microscope (SEM) and X-Ray Fluorescence (XRF).

Compressive strength test was carried out on paste at the age of 3 and 14

days. The result showed that the highest compressive strength at 14 days

was 13.93 MPa with 12 M NaOH.

Abstract Fulfillment of fish demand in the world is generally obtained by capturing

fish in the sea or on land, as well as fish farming (aquaculture). Recently,

fish production using aquaculture cultivation has rapidly increased either

on land or on shore and been expected to be able to exceed the amount of

capture fish production in the future. This will become a potency which

should be developed in Indonesia, as an archipelago. However, offshore-

aquaculture in Indonesia is kind of new and becomes a pilot project

adopted from similar program carried out by Norway. To identify the

readiness of this program becoming sustainable to be applied in the coast

of South Malang, there is a need to research and conduct social mapping

in order to view and analyze socio-culture, economy, environment aspects

linking with community engagement. Social mapping is conducted

qualitatively and quantitatively by collecting and analyzing demographic,

geographic, sociological data, then transferring into framework and

conceptual model. The framework of social mapping will become an input

for sustainable community based offshore-aquaculture model which can

be simulated to forecast how sustainable the program is in the future.

Abstract Garlic production depends on the garlic harvest season, which triggers

prices to fluctuate. Furthermore, peeling garlic can cause burning

sensation on our hands caused by Alliin substance. Extraction of natural

materials conventionally takes a long time and thus we need a faster

method that is by using Microwaves-Assisted Extraction (MAE) and

Microwaves-Assisted Ultrasonic Extraction (MUAE) methods. Garlic

slices were mixed with 96% ethanol and put into extraction flask. The

maceration process lasted 30 minutes before being put into the

microwaves. The same treatment was carried out on the MUAE method by

adding ultrasonic waves. Extraction time lasted from 30 minutes to 240

minutes. The results of the research shows that the best method obtained

was MUAE with optimum yield of 14,09% for 150 minutes, organosulfur

levels of 22,95% and could reduce energy consumption to 65%

Abstract Citronella (Cymbopogon winterland) is an organic material that contains

essential oils. Citronella oil extract (Cymbopogon winterland) was

obtained using the Microwave-Assisted Hydrodistillation method.

However, with this method, the yield obtained is still not optimal, and the

power used is still quite high. Therefore, in this study, a comparison of the

citronella extraction process was carried out between the Microwave

Ultrasonic Steam Diffusion (MUSDf) method and the Microwave Steam

Diffusion (MSDf) method. This MUSDf method is expected to be able to

produce a number of quality products with lower energy consumption

values. The variables used are the time of contraction 5, 15, 25, 35, 45,

55, and 65 minutes. From the research that has been done, it was found

that the MUSDf method was able to produce a yield of 0.8484% at the

optimum time of 45 minutes. The use of this MUSDf method is better in

extracting citronella essential oils with an increase in yield of 35.7%, an

optimum faster time of 18%, the bioactive content of citronella produced

by MUSDf is higher 0.94%, and lower production costs 39.13% compared

to the MSDf method.

Abstract This study was conducted to determine the suitability of the observed

equilibrium and kinetic model as well as the removal of acid violet 17. The

batch experimental variables include the dyes initial concentration and

the ratio of the adsorbent mass to the volume of the solution. The

adsorption equilibrium data were examined using three equilibrium

models i.e. Linear, Freundlich and Langmuir. The observed model is

limited by two forms of the proposed kinetic model. The first model just

consider the convection mass transfer of the dyes to the external surface

of the adsorbent, while the second model also takes into account the solute

diffusion in particles. The experiment result showed that the adsorption

process follows the Langmuir correlation with the adsorption capacity of

185.19 mg/g. From this study, it was found that the adsorption is

controlled by the diffusion stage inside the particle. The dyes removal

reach 58% which was achieved when 0.0015 gram adsorbent was used

per ml solution. The results of this study can contribute to the design of

the commercial scale adsorption process.

Abstract Solar Power Plant is one of the power plants that utilize solar energy into

electricity. Important data generated from electrical energy can be in the

form of voltage and current where measurements are made by a

multimeter whose measurement results cannot be done remotely and

cannot be stored automatically. Therefore it is necessary to design a tool

that can measure voltage and current from electrical energy over long

distances whose value can be automatically stored in a database and can

be displayed on the website. This system is built from GSM SIM800L as a

data sender, Arduino Uno has to process data, Voltage Sensor as a voltage

sensor and ACS712-30A as a current sensor. The level of accuracy of

measurements on currents if the manual measurement is used as a

reference is 30% and if the automatic measurement as a reference is 45%.

In voltage measurements, the level of accuracy if the manual measurement

is used as a reference is 2% and if the measurement is automatically used

as a reference is 2%. Which is the lower the level of accuracy the better

the value and if the greater the level of accuracy the value is less good.

Abstract In continuous bioreactor, feed is added and product stream is removed at

a constant rate. The aim is to maintain the system at a steady state with

high product formation. This can result in a highly productive process,

with comparably low operational cost. However, there are operational

challenges, especially at industrial scale, as it requires tightly controlled

conditions and robust monitoring methods. For long operation, the system

suffer a higher risk of contamination. This paper investigated PID

(Proportional integral Derivative) control strategy of a continuous

bioreactor. Several tuning methods of PID controller were used for

controller parameters determination (i.e. Direct Synthesis, Ziegler-

Nichols (Z-N) and Tyreus-Luyben (TLC)). Closed loop simulation results

for servo problem were presented in this paper for each method and

compared. The results showed that the three method works well

qualitatively. However, the process model of the system need to be

modified by introducing 5 hrs time delay, which is useful in obtaining

cross over frequency and to make PID possible in Direct Synthesis

method.

Abstract The power sensor measures single phase electrical power involving both

a voltage and current sensors. This sensors' pair utilizes full-wave rectifier

and differential amplifier as signal conditioning circuits for sensing

voltage and current, respectively. Power can be obtained with

multiplication between voltage and current. In this study, the alternating

current is converted to direct current using a full-wave rectifier by

calibrating a capacitor filter to understate the ripple voltage. In addition,

the differential amplifier yield output voltage interpreting line voltage and

current in root mean square for voltage and current sensor, respectively.

The work within this study develops voltage and current sensors to

measure power on load from a grid. We deploy a theoretical calculation

to calculate ripple voltage, peak voltage, mean voltage of rectifier, as well

as output voltage of differential amplifier. Additionally, we simulate the

voltage and current sensor circuit to verify the theoretical results with

applying different alternating current power. The results indicate that the

voltage and current sensors can be effective for measuring single phase

electrical power.

Abstract The development of the industrial sector, automation has become the core

of the manufacturing process and material handling. The process is

requested at the movement of goods from one location to another. Gantry

crane is a tool that can help in the process of moving heavy loads from

one location to another. Such a transfer process occurs that is unstable

which causes the movement carried out by the load. If an unstable swing

will continue to occur, then the gantry crane will be reduced. In addition,

it also causes decreased production efficiency and inefficient time spent.

The industry needs a crane that moves stably. In this study the authors

discuss, implement and analyze the movement of the prototype gantry

crane using fuzzy logic and Proportional-Integral-Derivative (PID)

methods. This approval system works with input from an absolute rotary

encoder sensor and an additional rotary encoder available on the

prototype gantry crane. The fuzzy system logic that is applied accepts

entering errors (e) and delta errors (Δ e), whereas in the PID control

system the values entered contain Kp, Ki and Kd. The process of

information is the output of the dc motor speed as an actuator in Pulse

Width Modulation (PWM). The final speed of the actuator is processed

based on the setpoint and changes needed from the reading of the second

sensor value. Making prototype gantry cranes can achieve equilibrium.

Gantry cranes can maintain stable rope cranes with or without

interference. The time needed to achieve stability when not using anti-

shake is 158.35 with the farthest drift 17.52 °. The system that uses anti-

shake with the fuzzy logic method takes 10.49 seconds to achieve stability

with a 3.52 ° deviation, while the PID method takes 7.02 seconds with the

furthest 4.72 ° deviation.

distribution system is a circuit breaker and relay. The Zone Selective

Interlocking (ZSI) method will be applied to the overcurrent relay and

ground fault relay settings. ZSI will determine priority areas that should

not experience blackouts and minimize trips by eliminating sources of

undergraduate program in the Kalimantan Institute of Technology (ITK)

ends with the writing of final project, in which students have to follow the

research methods and grammar rules of scientific writing (ITK, 2018).

There are several processes that needs to be followed in order to finish the

final project, namely registration, proposal presentation, research &

supervisory, and final project defense. There are also 18 forms that needs

to be filled throughout the final project process. Problems occurred due

to no information systems to support this business process, leading to

missing forms, missing informations in each forms, ineffective supervisory

activities, and past deadline final project completion. To solve these

problems, it is necessary to do business process automation for the entire

process of the final project. In this study, the method used was part of the

life cycle of Business Process Management (BPM), namely business

process implementation. The steps that was taken in this method were

confirm the process model, identify automation boundaries, task manual

review, complete the process model, bring the process model to an

adequate granularity, and specify the execution process. The results

obtained from this study were the Final Project Information System had

been implemented using ProcessMaker and there were 13 proposed

process improvements in the Final Project Guidelines.

Abstract Construction projects are highly dynamic, but have a lot of risks in every

field of work. To reduce the occurrence of a risk to the project, it is

obligatory to do project risk management to avoid losses to the project

time, cost, and quality. Evaluation of risk management also needs to be

done to improve the quality of project risk management. Hence, this

research aims to improve project management in one of the project-based

organizations in Indonesia by measuring the maturity level of project risk

management. This research uses the Project Management Maturity Model

(PMMM) as its framework with seven risk management processes as its

criteria. This criterion will be used to compile a self-assessment survey

that will be disseminated to gather evidence. In this research also carried

out the weighting and ranking of these criteria using the Analytical

Process Hierarchy (AHP) method. The results of this research found that

from the results of weighting and ranking that the criteria of priority is

plan risk management, and the maturity level obtained in the six risk

management processes at level 1which is the initial process, and one

process at level 4 which is the managed process. Overall, the maturity

level of PBO project risk management is currently at level 1, which is the

initial process.

Extending Lifetime of Wireless Sensor Networks by

Reducing the Overhead on the Cluster Head Nodes

Mohamed Kayed1, Ahmed Anter2, Ahmed Hassan3

1,2,3Beni-Suef University

Abstract Clustering sensor nodes in a power constrained Wireless Sensor Network

(WSN) is an efficient step to enhance the energy efficiency and extend the

network lifetime. Clustering gives many advantages (e.g., data

aggregation and less number of transmissions) that greatly reduces the

energy consumption of the WSN. A Cluster Head (CH) node is selected for

each cluster to receive data from the cluster's nodes, aggregate them and

finally transmit these data to a Base Station (BS). However, the overhead

on the CH nodes is still a problem for the network lifetime which causes

premature death for those overloaded nodes. Energy harvesting is one of

the most energy optimization techniques that makes the WSN rechargeable

and so extends the lifetime of the network. Traditional techniques such as

solar and wind harvesting are not reliable because they are neither

constant nor always available. Another type of energy harvesting is the

Wireless Power Transfer (WPT) approach in which a node enables to

transfer energy to other nodes. According to the energy consumption

theory in WSN, about 90% of energy is left unused after the premature

death of overloaded nodes. If this big surplus of energy is used to recharge

the overloaded nodes, it will greatly extend the lifetime of the WSN. So, in

this paper, we use the WPT technology and the multi-objectives Particle

Swarm Optimization (PSO) to extend the network life time. The target of

our proposed approach is to minimize the amount of this surplus of energy.

All nodes in the WSN will transfer energy to the CH nodes to distribute

the overall load. At the same time, the optimal amount of energy,

transferred by each node, must also be convenient to its residual energy.

Therefore, this paper tries to eliminate the overhead on the CH nodes and

therefore extend the lifetime of the clustered WSN. Our simulation results

show an encouraging result to extend the lifetime of the WSNs as

compared with the common Leach algorithm.

Abstract The development of Science Techno Park in Indonesia has a goal to

increase economic growth and strengthen the role of science and

technology. The European Union as a country that has known Science

Techno Park since the mid-1960s, in 2013 compiled the Science Techno

Park model and stated that the success of the Science Techno Park was

influenced by three dimensions, namely economic, sustainability and

process improvement. So that the adaptation of the European Union

Science Techno Park model to Science Techno Park in Indonesia is done

in designing the performance measurement system. The design of the

performance measurement system consists of the formulation of indicators

on the dimensions of the Science Techno Park based on applicable rules

for the Science Techno Park Indonesia including the assessment of the

maturity of the Science Techno Park, display performance indicator

properties, and trials at the Science Techno Park in Indonesia. The results

of the trial show that Science Techno Park in Indonesia already has

targets and documents on performance, but there are still a number of

targets and realization that do not have data availability

Abstract This research compares the performances of two metaheuristic methods:

Particle Swarm Optimization (PSO) and a hybridized PSO method with

Greedy Randomized Adaptive Search Procedures (GRASP) for solving

aircraft maintenance problems (AMP). In this problem, AMP consists of

two different maintenance activity types: inspection and continuous

airworthiness maintenance programs (CAMP). The purpose of this paper

is to determine the number of periods that the aircraft needs to be

maintained and which inspection and CAMP tasks need to be done in each

period. The problem is NP-Hard in nature so that metaheuristic methods

are used to make sure the optimization process can be solved quickly.

Computational experiments are performed by using 16 conditions and

four randomly generated dataset instances. The computational experiment

result shows that PSO-GRASP outperforms PSO for a larger planning

horizon.

Abstract Lean concept has been discussed extensively across many industries. As

its approach to ensure overall performance by focus on delivering

customer's expected value. Any activities within industries that don't

contribute to value the end product will consider as waste and need to be

eliminated. The lean idea for Bogie production process useful to identify

the potential improvement on production performance in terms of

manufacturing lead time (MLT) or cycle time. Carefully analyse on the

cause of waste may guide to address on the root cause, one of them is

maintenance problem. Therefore, the continuing lean implementation on

maintenance activities may lead to solve another root cause. It

successfully showed the potential escalation on MLT about 20% reduced

by considering the manufacturing waste. Further advantage and benefit

may gain more due to lean maintenance implementation albeit the exact

improve performance still need to be detailed quantified

Abstract Supply chain system in fertilizer industry is quite complex because it

involves many activities such as, internal logistic, material transportation

processes, a number of factories, and warehouse management. The

process of raw materials handling that starting from the port to warehouse

is very influential on the company's ability to carry out operational

activities in the production department. To improve the competitiveness of

the company, case company needs to take a number of strategic steps and

running a transformation program for becoming an efficient, integrated

and sustainable fertilizer producer. The problems that occur in the

inbound logistic activities at case company are the raw materials stored

in warehouses often overcapacity, causing a material accumulation when

there are new raw material arriving at the port. Therefore, warehouses

are need to periodically reorganize its storage in order to keep operating

in efficient manner. This research aims to help overcome the problems that

occur in company by examining several alternative solutions in inbound

logistic activities to reduce material transferred between port, production

warehouses and buffer warehouses by using model simulation method.

The method that is going to be used to solve this problem is the Discrete

Event Simulation (DES), in which the improvement system does not

disrupt the existing system and doesn't cost too much time and money. This

research proposed a scenario of warehouse capacity re-allocation for raw

materials by prioritizing highest frequency of raw material arrival. By

using the improved system, it reduces the total average volume of material

transferred from port to production warehouses by 13.29%, from port to

buffer warehouses by 10.21% and from buffer warehouses to production

warehouses by 17.43%.

Abstract The Transportation Model which has been widely applied in the allocation

and distribution of goods has not been able to be used for the allocation

and distribution of electricity. This is because there are differences

between the electrical properties and the properties of goods. The first

difference is that electricity cannot be saved, this difference causes excess

production to be wasted. The second difference is that electricity must

always be available at all times. Power plant scheduling usually uses

economic dispatch, but this model has not considered optimization in

transmission and distribution networks. Therefore, this research proposes

a new model called Single Echelon Economic Dispatch (SEED). This

model is a combination of the transportation model and the economic

dispatch model. This model is able to do a joint optimization between the

production and transmission / distribution sides. The SEED model is used

to develop a collaboration strategy between electricity suppliers in East

Kalimantan. Simulation results with cost parameters: The best

collaboration when the load is low is PLN + IPP, while at the peak load

the best collaboration is the Joint of all electricity suppliers

Abstract Aquaculture method has been well known in Indonesia for a long time.

Inland aquaculture such as brackish water pond is a common practice

for more than couple hundred of years. However, it is not the same case

for marine aquaculture especially for offshore. Fish demand is

continuously increasing following the growing of world population. In

spite of this, the number of wild captured marine fish is relatively stagnant

for the last 30 years and there is a need to ensure sustainability of marine

ecology. To deal with this challenge, Indonesia Ministry of Marine Affairs

and Fisheries (MMAF) has a pilot project to instal and operate offshore

aquaculture. Furthermore, this program is also aiming at providing more

job opportunities for community, ensuring food security and increasing

contribution of fisheries sector to National GDP. To ensure successfulness

of this business, offshore aquaculture operational risk management is

required. The purpose of this study are to identify, assess, evaluate and

propose treatment action for potential risks during offshore aquaculture

operations by adopting House of Risk method. This study identifies 47 risk

events and 67 risk agents (source of risk events) of offshore aquaculture

operations. Five risk agents are selected and suitable treatment actions

are proposed accordingly.

Abstract In many accidents that have been occurred in maritime industry, the root

cause of accidents is unsafe behaviour of the workers. This research aims

to analyse the factors that motivate safety behaviour in shipyard workers.

The model that will be used refers to Social Cognitive Theory (SCT). There

are five variables used, which are environmental factors (FL),

management commitment (KM), safety-efficacy (SE), employee

involvement in safety (TK), and work safety behaviour (PA). From those

five variables 11 research hypotheses were established. Data collection

conducted by distributing offline questionnaires to field employees,

supervision, and safety management at PT. DTPS. The number of

respondents involved was 173 respondents, which then modelled using

structural equation modelling (SEM) method. The result are four of the

eleven hypotheses were rejected. It also found that TK played an important

role in motivating safety behaviour in the workplace. The most influential

factors are TK and SE. Therefore, it is needed to change the behaviour

and culture of an individual at the workplace in order to improve safety

behaviour.

Abstract The last decade has seen growing interest in and practice of

environmentally sustainable operations in emerging economies like

Ghana. However research into the drivers and outcomes of

environmentally sound operations of manufacturing firms in Ghana has

been largely lacking. This study develops a research model which

proposes that environmentally sustainable operations is driven by

leadership commitment and results in improved firm performance. Data

to test to the research model was derived from a survey of 334

manufacturing firms operating in Ghana, and was analyzed using partial

least squares structural equation modeling (PLS-SEM). Results of the

study confirmed that leadership commitment had a significant effect on

environmentally sound operations, which in turn significantly impacted

firm performance. The implications of the study are discussed.

1,2,3Institut Teknologi Sepuluh November (ITS)

Abstract Occupational accident data based on Social Security Administrator

(BPJS) Employment of Indonesia shows an increase from 2017 of 123,041

cases and in 2018 of 173,105 cases. Work accident cases consist of light,

moderate, severe, and fatality categories. The high fatality cases occur in

traffic accidents, manufacturing, and construction. The high fatality in

construction occurs due to the characteristics of construction projects

involving equipment, permanent workers and subcontractors,

construction work methods, and open fieldwork. The human factor is

essential in construction. Workers have contributed as a cause of

accidents due to unsafe actions they take. Knowing the level of maturity of

safety in construction projects is important to prevent work accidents.

Therefore, in this research, a safety questionnaire was designed in the

field of construction so that it can be used to assess the safety maturity

level of a construction project. The method used is a literature study on

the level of safety maturity in manufacturing and in-depth interviews with

relevant parties in construction projects of apartments, offices, and

mallsandgt; 20 floors. The questionnaire was prepared considering three

aspects, namely psychological, behavioral, and situational. While the

factors considered are Information and Communication (IC),

Commitment (CM), Organizational Learning (OL), Leadership (LI) and

Competence (CP). The final results obtained are three types of

questionnaires, namely HSE Questionnaire with 40 questions,

Staff/Management Questionnaire with 25 questions and Foreman and

Worker Questionnaire with 15 questions. The data processing of this

questionnaire is using a fuzzy method. Furthermore, this questionnaire is

used to assess the construction project to determine the level of maturity

of its safety at the level of pathological, reactive, calculative, proactive or

generative.
