Abstract
The purpose of this research is to develop a decision support system in the herbs production scheduling appropriates to Good Traditional Medicine Manufacturing Practices (GTMMP).Design of algorithm modelfor scheduling decision support system that complies with GTMMP standard was done using a network analysis technique, which combines the techniques Evaluation and Review Technique Program (PERT) and Critical Path Method (CPM). The structure of decision support systems consists of database management syatem and modelbase management system. The implementation of decision support systems is the consideration for companies that intend to certify GTMMP.

1. Introduction
Harmonization of ASEAN as a trade agreement between ASEAN countries and China requires herbal medicine manufacturers that are wished to export their products to other countriesmust have a safety certificate as Good Traditional Medicine Manufacturing Practices (GTMMP). This is in line with business policies that enable efficient management of the established standard operating procedures for daily activities (Peltier, 2004). In fact, it is not easy for an industry to adopt the GTMMP standard. Among many herbal industries in indonesia, there are only 32 companies having certified GTMMP (Ministry of Health, 2011).
Implementation of GTMMP is not easy when an industry to adopt that standard. The standard reference choice in GTMMP implementation is based on the determination of an efficient production schedule. Furthermore, as a mean of supporting decision-making, companies can take advantage of computer technology, especially using project planning application on the production process that implements GTMMP. Because of a production system with standard GTMMP has not been available yet, using the term pilot project as an analytical tool can be an option. It is an alternative way to assess the production system feasibilityby usinga project management tool. Hopefully, the herbal industry can decide if the GTMMP pilot project that can be used as a standard operating procedures. The

purpose of this research is to produce a decision support system in the herbs production scheduling appropriates to Good Traditional Medicine Manufacturing Process (GTMMP).
2. Research Method
The method of this study consists of three stages. The first stageis the construction ofa databasemanagement system. The second stageis the construction ofmodelbasemanagement systemschedulingproduction processes using PERT and CPM technique. The third stageisto integratethe databaseand the modelbaseintoa productionschedulingdecision supportsystemaccording tothe GTMMP standard. 3. Result and Discussion 3.1 Requirement Analysis
In order to buildthe decision support systems, the database and the modelbase management systems are needed.
The database management system is used to process the data. The data are entered and stored in a database management system which can be retrieved when they are needed.Based on related informationof theproductionofvarious herbs industrialguidedby NA-DFC, the network can be madeas a pilotproduction project. The seven processescontaining inthe production modelof traditional herbal medicineareillustratedin the Figure 1.

The output of the method is used as an input of PERT CPM method that will be used again with the output of the CPM method for scheduling activities. 3.5IdentificationSystem
Tocarry outthe production processing accordancewith GTMMP, a framework based on the determination of GTMMP implementation is needed. An engineeringmodelof herb productionschedulingwas designedin a computer based Decision SupportSystem (DSS). The configurationmodel is presentedin the following figure.

For performing PERT analysis, one needs to fill the data of every actvity in the form provided by PERT analysis
tool box, as presented in Figure 4.
The next step is to get PERT analysis to provide the users for the optimistics, pesimistics and expected Gantts.
The result of PERT analysis must be saved first to be used in CPM analysis afterwards. To get a graph of the fast
schedule after together along with the critical activities, one can choose the desired graph presentation of Gantt chart. The networkdiagramformedicinalproduction schedulebasedGTMMPthen is displayed below.
Production scheduling is a process to allocate appropriate resources for the required manufacturing tasks (Baker,
1974; Xue, Sun, &Norrie, 2001). Based on thescheduling, the time of the herb production processbased onthecriticalpathis 13306.33minutes. The expectedtimeduration should be used tooptimizethe production under resources constraints (Davis, 1973; Elsayed, 1986; Elmaghraby, 1993; Chan, 1997). Otherwise, PERT-CPM integratedschedulingprovides an opportunityto acceleratethe completion ofthe production processthrough the calculation ofthe probability, so it canbe acontrolforthe production process (Ballard & Howell, 1998; Chua, 1999). In reference to thenormaltable, there isa 50%chancefor thecompany to completethe productionin 13306.3minutes. The 50% of chance means the scheduleof the production processcan be acceleratedorslowed down. There is opportunityto accelerate thecompany'sproduction processes into12 960minutes or less with the chanceof20.33%.
Byutilizinga computing technology,it is expected to acceleratethe more accuratecomputation process(Andersen, 1995; Chan, 1997; Xue, Sun, &Norrie, 2001) and quickerone (Bonfatti & Manari, 1995; Mezgar, Kovacs,

Decision support systems consists of database management syatem and model base management system.
Implementation of decision support systems is the consideration for companies that intend to certify GTMMP. By utilizing a computing technology it is expected to accelerate the more accurate computation process and
quicker, besides allowing leeway to choose the value of critical activities as the basis for scheduling, especially for small and medium industries.
