Saturday. This day is standard day for cleaning factory and also a standard

operating procedure for every factory.

13

3.0 CONTENT OF TRAINING

In the content of training, the main activity in the 10 weeks has been explained with aid of

illustration.

3.1 THRESHER DRUM

Thresher drum is a main component found in thresher station which separate oil palm fruit

brunches by rocking slam in a rotating drum to make the process of threshing the fruit of the

bunches of fruit that goes from the auto feeder was slammed with a round drum which

normally have (23 rpm) and with the help of a stripper which is on drums. Fruit will be lifted

and slammed so the fruit falls off from bunches. Through the grating drum, brondolan fall

onto the conveyor under threshers while empty jajangan pushed out by referring to the

horizontal plate bunch empty inclined conveyor next to a conveyor leading to the empty

bunch hopper.

3.1.1 MEASUREMENT DIMENSION OF THREHSER DRUM

First week, the intern has given a task to measure of thresher drum. There are two thresher

drum put in the factory of YI DA Engineering. Since, they are similar therefore only one of

the thresher drum have been measured. The dimension of the thresher drum has been

measured and record in a piece of paper.

The measurement tool used in this activity is measuring tape, vanier caliper and outside

caliper. Measuring tape is used to measure the certain length of thresher drum and vanier

caliper is used to measure the thickness of bar found in thresher drum. For outside caliper, it

used to determine the diameter of the shaft with semi-precision

14

There are some of problems have faced in the activity:

1. Lack of knowledge on usage of measurement tool

2. Some part of thresher drum is hard to measured

3. The dirt on thresher drum affect the performance of activity

4. The environment is hot

3.1.2 DRAWING OF THREHSER DRUM

Later, the thresher drum is drawn in AutoCAD. The recorded dimension is used in drawing.

The front, side, and some detail is drawn according the sample given by supervisor. Since the

work is large, therefore it was divided into several parts among colleague. However, there are

some parts of dimension is modify according to the requirement which has given by

supervisor.

3.2 P&ID FOR PALM OIL MILL

The term P&ID stated here is pipe and instrument diagram which is a plan view diagram

shows the process flow of palm oil mill from one machine to others with symbol. The

symbols in the P&ID normally represented the valve, joint, controller, mechanical flow meter,

recorder, pump and etc.

The example of P&ID symbols is show as below:

4. STERILISER P&ID COMPLETE

17

3.2.2 COMMON TYPE OF VALVE

During the process of drawing, the intern has meet different type of valve. However, the three

common types of valves found in market are:

1. Butterfly Valve

The figures above are the picture of butterfly valve and symbol of butterfly valve.

A butterfly valve is a valve which can be used for isolating or regulating flow. The

closing mechanism takes the form of a disk. Operation is similar to that of a ball valve,

which allows for quick shut off. Butterfly valves are generally favored because they

are lower in cost to other valve designs as well as being lighter in weight, meaning

less support is required. The disc is positioned in the center of the pipe, passing

through the disc is a rod connected to an actuator on the outside of the valve. Rotating

the actuator turns the disc either parallel or perpendicular to the flow. Unlike a ball

valve, the disc is always present within the flow, therefore a pressure drop is always

induced in the flow, regardless of valve position.

2. Ball Valve

The pictures above are picture of ball valve and its symbol. A ball valve is a form of

quarter-turn valve which uses a hollow, perforated and pivoting ball (called a

"floating ball") to control flow through it. It is open when the ball's hole is in line with

the flow and closed when it is pivoted 90-degrees by the valve handle. The handle lies

18

flat in alignment with the flow when open, and is perpendicular to it when closed,

making for easy visual confirmation of the valve's status

3. Gate Valve

A gate valve, also known as a sluice valve, is a valve that opens by lifting a round or

rectangular gate/wedge out of the path of the fluid. The distinct feature of a gate valve is

the sealing surfaces between the gate and seats are planar, so gate valves are often used

when a straight-line flow of fluid and minimum restriction is desired. The gate faces can

form a wedge shape or they can be parallel. Gate valves are primarily used to permit or

prevent the flow of liquids, but typical gate valves shouldn't be used for regulating flow,

unless they are specifically designed for that purpose. Because of their ability to cut

through liquids, gate valves are often used in the petroleum industry. For extremely thick

fluids, a specialty valve often known as a knife valve is used to cut through the liquid. On

opening the gate valve, the flow path is enlarged in a highly nonlinear manner with

respect to percent of opening. This means that flow rate does not change evenly with stem

travel. Also, a partially open gate disk tends to vibrate from the fluid flow. Most of the

flow change occurs near shutoff with a relatively high fluid velocity causing disk and seat

wear and eventual leakage if used to regulate flow. Typical gate valves are designed to be

fully opened or closed. When fully open, the typical gate valve has no obstruction in the

flow path, resulting in very low friction loss.

19

3.3 SPECIFICATION OF ENGINEERING PRODUCT

In engineering field, specification of engineering product is very import because most of the

products have their own specification according to standard or company itself. Therefore, the

designers have to take the specification of engineering product or component as consideration

to fulfill the requirement of design.

There are several tasks have done by the intern is related to specification of Engineering

product. The tasks are 2D-library add on and making of common size material list. For 2D-

library add on, the intern have been drawn several common size of engineering components

such as I-beam, sprocket and bolt. For common size of material list, the type of engineering

materials have been separated and then unit weight is shown for each type of engineering

materials with its specification and material. The purpose of doing this is to make the project

manager convenient to calculate the weight of material.

Furthermore, the handbook often refer by YI DA Engineering Sdn Bhd is Yi Hock Handbook

Engineering Handbook where inside have specification for different type of engineering

product such as I beam, angle bar, flat bar and etc. Beside that other catalog also have been

refer such as catalog for sprocket.

Some of engineering products are shown below:

1. I-BEAM

An I-beam, also known as H-beam, W-beam (for "wide flange"), Universal Beam (UB),

Rolled Steel Joist (RSJ), or double-T (especially in Polish, Bulgarian, Spanish, Italian and

German), is a beam with an I- or H-shaped cross-section. The horizontal elements of the

"I" are known as flanges, while the vertical element is termed the "web". I-beams are

usually made of structural steel and are used in construction and civil engineering.

20

The web resists shear forces, while the flanges resist most of the bending moment

experienced by the beam. Beam theory shows that the I-shaped section is a very efficient

form for carrying both bending and shear loads in the plane of the web. On the other hand,

the cross-section has a reduced capacity in the transverse direction, and is also inefficient

in carrying torsion, for which hollow structural sections are often preferred. The material

are mild steel and stainless steel.

2. BOLTS AND NUTS

For bolt and nut, there are two different systems which is metric system and inch system

for their dimensions. Metric system using SI unit however inch system using BG unit.

However, the standard used by YI DA Engineering is JIS 1008 Grade A and which is

hexagonal head bolt in both metric and inch system.

3. SPROCKET

21

A sprocket or sprocket-wheel is a profiled wheel with teeth, cogs, or even sprocket that

mesh with a chain, track or other perforated or indented material. The name 'sprocket'

applies generally to any wheel upon which radial projections engage a chain passing over

it. It is distinguished from a gear in that sprockets are never meshed together directly, and

differs from a pulley in that sprockets have teeth and pulleys are smooth.

For sprocket, there are some important dimensions have follow there are chain pitch,

pitch circle diameter, bore diameter and number of teeth.

3.4 WELDING

By inspection around the factory we observed that the factory main activity is welding. Arc

welding and oxy-acetylene welding is the most used typed found in factory.

22

3.5 UNFOLD TECHNIQUE

Unfold technique is the engineering technique learned in YI DA Engineering Sdn Bhd. The

unfold technique is important because we need to know the size and geometry of metal sheet

to cut before folded into required ducting shape. The accuracy is needed during this process

therefore the drawing methods have to be correct and accurate. The interns have learn

difference unfold techniques during the training there are pipe segmentation method, 2D

drawing method for square to round ducting and usage of unfold function of SOLIDWORKS.

There difference orientation of ducts or pipes connection, however in YI DA Engineering

Sdn. Bhd only consider on:

1. Unfold of 90 bend or elbow

2. Unfold of square to round duct

3. Unfold of segmented pipe tee

3.5.1 PIPE SEGMENTATION METHOD

The pipe segmentation method is used to unfold 90 bend or elbow. The fundamental

principle of segmentation method is numerical method to draw the shape of unfold for every

orientation of connection. During usage of pipe segmentation method the interns have

discovered the reason of every step pipe segmentation method. Before going any detail, the

steps of pipe segmentation have been shown:

1. Draw a view of the pipes that shows the angle of intersection.

2. Draw a circle under the vertical pipe and divide it into 16 equal spaces and number as

shown.

3. Extend vertical lines from the point where the lines drawn in #2 intersect the circle to

the angle of cut.

4. Obtain the circumference of the pipe by multiplying the diameter X 3.1415.

5. The length of this line will be that obtained in step 4.

6. Subdivide the line drawn into 16 equal segments and number the lines 1 to 9 then

back down to 1 as shown.

7. Intersect the numbers as show. (1 to 1, 2 to 2, 3 to 3 etc..)

8. Draw a line through these intersecting points as shown then cut out the template.

9. Wrap the pipe and mark and counterpunch.

23

10. Cut with a torch keeping the tip pointed towards the imaginary intersection of the two

pipe centerlines.

The important key for this theory is the relative height of line for position 1 to 9 by taking the

position of height for 1 as origin. With these relative height a curve can be drawn by

connected all these point. However, the curve is just an approximate curve for further

accuracy more position might be used to the relative height of them.

However, to trace the relative height the vertical lines from each position of the bottom circle

to the line of cut is drawn, but by doing this we just can get the relative height therefore

another horizontal line is drawn to intersect the straight line beside with respective position.

The point of intersection can be used to drawn the shape of curved after unfold. However

only half of curved have been plot another half have to plot using the same way.

Therefore, by using this method any orientation of pipe with different cut of line can be

unfolded. The 90 bend or elbow and segmented pipe tee can used this method to draw

although the cut of line is different. For 90 bend or elbow, the cut of line is just a inclined

line. However for segmented pipe tee the cut of line is a curved line.

24

3.5.2 2DRAWING METHOD FOR SQUARE TO ROUND DUCTING

Square to round ducting is a ducting with two ends with difference geometry shapes. There

are round and square as shown as below:

The step of drawing of unfold pattern for square to round is shown as below:

First step is to find all true lengths. The only way to able to see a true length line is

perpendicular to its plane. Develop a true length bar. Using the dividers or trammel points,

transfer from the top views points A1, A2, A3, A4, A5, A6, B6 and B1.Draw a line from the

top of your True length bar (which must be the total height of the fitting) down to each

reference mark on the base of the true length bar

25

Take the dimension A to A from the top view and draw a straight line. Set the dividers to

dimension A to B and draw a small arch as a reference point. Once the dividers are set, place

one end on A and make a reference mark as in Fig.1.

Set the dividers on points 6,5 in the top view and transfer this dimension to the

drawing as in Fig.2

Set the dividers to the A5 length from true length bar and make a reference mark that

intersects with 6,5 reference mark

Reset the dividers to the distance of 5,4 from the top view and transfer this to the

drawing.

26

Continue what were doing in Fig.2 until all A6 through A1 lines transferred.

Determining line B1, B is half the distance from A to A and referenced this with an arch.

Transfer line B1 from the true length bar by setting the dividers to that distance and

transferring it by placing one end on point 1 and drawing an arch across the arch is labeled B.

The intersection of these two arch's becomes point B. Draw a line from point 1 down to point

B and draw another line from point A to point B 2 pieces required to make one fitting. One

last thing to do is to connect the points 1 through 6.

27

3,5.3 SOLIDWORK

However, the quickest way to unfold these things is usage of SOLIDWORK. The picture

below shows picture of unfold for these things:

1. Unfold of elbow:

The picture above is unfolds of one segment of elbow, unfold of elbow has curved

line.

2. Unfold of pipe-tee

The picture above is unfolds of pipe-tee where the pipe head to another pipe is

unfolded which has almost similar shape as elbow.

3. Unfold of square to round duct

The picture above is unfold of square to round duct.

28

3.6 PALM OIL MILL

Palm oil is extracted from fresh fruit bunches (FFB) by mechanical process, where a mill

commonly handles 60 to 100mt per hour of FFB. The modern palm oil mill of today is based

predominantly on concepts developed in the early 50s (Mongana Report). An average size

FFB weighs about 20-30kg and contains 1500-2000 fruits. The FFBs are harvested according

to harvesting cycles, and delivered to the mills on the same day. The quality of crude palm oil

is dependent on the care taken after harvesting, particularly on the handling of the FFBs.

A palm oil mill produces crude palm oil and kernels, as primary products and biomass as

secondary product. The capacity of mills varies between 60- 100 tons FFB/h. A typical mill

has many operation units as shown in Figure 2. This comprises of sterilization, stripping,

digestion and pressing, clarification, purification, drying and storage. For the kernel line,

there are steps such as nut/fibre separation, nut conditioning and cracking, cracked mixture

separation, and kernel drying, storage. The dried kernels are often sold to palm kernel

crushers for extraction of crude palm kernel oil. In some integrated plants, kernel crushing

facilities exist side by side at the same complex.

The flow chart shows the process of palm oil mills:

29

3.6.1 DRAWING OF SCHEMATIC DIAGRAM OF PALM OIL MILL

In this internship training, the intern have been drawn a lot of schematic diagram of palm oil

mill. Therefore, in this process the intern able to learn more about the palm oil mill process

but continual drawing of them. The title of drawing had been mention in section 3.2.1.

3.7 POME VAP

Palm oil mill effluent (POME) is the waste water discharged from the sterilization process,

crude oil clarification process and cracked mixture separation process. POME produced huge

amount of methane gas from its anaerobic process and has 21 times Global Warming

Potential (GWP) compared to the other gasses. However it can be solved, if it can be utilized

as fuel for power generation and cogeneration. Notwithstanding the huge potential, existence

of proven technologies and availability of knowledge and incentives, biogas utilization is still

in a very early stage in Malaysia.

Wastewater treatment facility is amongst the most important component in the palm oil mill

system. This is because the facility is to treatment palm oil mill effluent (POME) that is being

generated in large volume during the production of crude palm oil (CPO). Due to the

chemical and physical properties of POME, the most efficient system used in the initial stage

of the wastewater plant is the anaerobic treatment. The current systems meet the requirement

of the palm oil mill operators to safely discharge the treated POME. However, the systems

release one of the green house gases (GHG), CH4 into the atmosphere as the by-products of

anaerobic digestion of POME.

However, YI DA Engineering companies are planning on using POME VAP instead of

original water treatment system. POME VAP is usage of heat exchanger plate to drying and

concentrated the effluent to semi-solid or solid with little water content and final convert to

animal food by adding fiber on it. This will make the place for water treatment smaller and

the cost will be cheaper.

30

The flow diagram below is the schematic diagram of POME VAP:

3.7.1 Helping of doing proposal

The interns have chance to helping the project manager doing proposal for POME VAP. The

interns have helps the project manager finding information on POME VAP about the

maintenance of heat exchanger plate for Alfa Lava.

Some of the pictures about POME VAP have shown as below:

1. Type of heat exchanger:AlfaCond 600

3.9 MEASURE DIMENSION OF COMPOSER PLANT

During the internship period, the interns also have chance to visit palm oil mill at Kluang.

The purpose of visit is to go measure dimension of composer plant then come back to office

to draw the plan view for it then put the plan view picture to fit the location in existing palm

oil mill plan to update and renew information.

In measuring activity, two persons have been involved in measuring activity and one person

involve in recorded.

The dimension of distance between I-beam, width of drain, distance of drain from boundary

and distance of beam from one building to another have been recorded.

3.10 DESIGN PRODUCT

During the industrial training, the interns have given a task to design curved roofing on the

wall of 160ft long and 30 ft height. There are several design have been proposed and some of

the design are shown as below:

1. For first design, the roof is design as two half eclipses.

2. For second design, the roof is design as curved like shaped

36

3. For third design ,the roof is design as mountain shaped

From this design task, the intern have learned about for a design project is not no sufficient to

just fulfill physical requirement but the requirement of customer also have to take as

consideration because their comment is the most important part to make a design project

successful.

4.0 RECOMMENDATION

4.1 RECOMMENDATION FOR THE COMPANY

After 10 weeks of industrial training, some of the problems exist in the company have been

observed. There are some of recommendations have been given as below:

1. Using 3D software such as SOLIDWORKS.

Since, the company used AutoCAD as their drawing software. Therefore, the

company is suggested to use 3D software such as SOLIDWORKS. The reason why

SOLIDWORKS is recommended because it is more convenient to use compare to

AutoCAD to draw 3D drawing. The SOLIDWORKS has difference drawing

characteristic with AutoCAD due to SOLIDWORKS is dimension driven which mean

the drawing can be change by input dimension. It is slight difference compare to

AutoCAD which need to input dimension first before drawing. In other word, the

drawing in SOLIDWORKS can be modify but AutoCAD cannot and have to redraw

if meet mistake. Furthermore, the SOLIDWORK can used to stimulate and analysis of

product but the AutoCAD cannot. So, by using SOLIDWORK will enhance the

efficiency of company.

2. Using machine with higher precision.

After several inspections on factory, the equipment of cutting metal sheet is manual

cutting machine which mean the motion of cutting machine is control by hand. The

several disadvantages usage of this kind of equipment first vibration of cutting

machine will cause health problem of workers such as hand shake and reduce of

accuracy. Therefore, company may be could buy in some automation cutting machine

so that the worker can cut metal under safety environment and high accuracy.

3. Hire safety officer.

After observed the organization chart, the organization didnt hire safety officer.

However there is important to have a safety officer to guide the worker so that the

worker would work under safety environment. There are several situations I saw the

worker are unsafe while working. For example, the wrong standing position of worker

40

while lift up heavy things. This happen because dont have proper working procedure

hence safety officer is required to do hazard management in factory to make sure all

the workers are work under safety environment.

4.2 RECOMMENDATION FOR FALCULTY

The recommendation for falculty of mechanical and manufacturing engineering (FKMP) is

supervisor from FKMP should visit the trainees twice during the industrial training.

Supervisor from faculty should visit the trainee once in the first two weeks of their training to

make sure they are properly having their industrial training and once in the last two weeks to

evaluate their performance.

4.3 RECOMMENDATION FOR TRAINING SCOPE

There are some recommendation is given for training scope as shown as below:

1. Given students chance to go on-site if the company has this kind of opportunity.

As a mechanical student, they required many practical and contact to real life machine

instead of merely obtain knowledge in book. Therefore, go on-site is the best choice

to learn new thing and related what they seen to theory obtain from book. For

example, when installation of machine in factory student can observe and learn how

the workers install them.

2. Given project based task.

Furthermore, the LI supervisor may be can gave the interns a project base work to do

so that the interns can learn more thing and faster to adapt to environment by

cooperate with profession in engineering field.

5.0 CONCLUSION

As a conclusion, through this internship training program which offered by University of Tun

Hussein Onn Malaysia the intern have chance to explore to engineering working environment

for enhance professional skill and interpersonal skill as a professional in Yi Da Engineering

Sdn Bhd. The intern also have chance to communicate and cooperate with profession from

engineering field. Furthermore, the intern is also gain working experience from YI Da

Engineering.

In this internship program, the interns have given different task which required creativity,

technical skill, interpersonal skill and communication skill. Therefore, in this period the

intern has to connect work experience with knowledge learn from IPT by applied theory and

academic knowledge on work. Besides that, the intern also forced to enhance soft skill and

communication skill because without all these skill the interns would not survive in future

engineering works. Furthermore, the intern can obtain some experience and knowledge for

benefit of chooses work after graduate.

At last, the intern also learned a lot in YI DA engineering and have chance to explore in palm

oil mill industry. However, there are still have a lot of things need to learn because the intern

just have two month duration to go through the intern life.
