Abstract

Smooth production in a manufacturing firm is very important because it will affect the outcome of which is the expected output of the production trajectory balance that existed at the company if it is optimal or not. The objectives to be achieved in this research is balancing production trajectory so that the expected target company can be reached, drink idle time, and improve the efficiency of the production trajectory. At PT METBELOSA there are trajectories that have not been balanced by the production of idle time on the final line for assembling OB91Z 1.606149 minutes, balance delay in assembling the final line OB91Z by 29.75% and the efficiency in assembling the final line OB91Z of 70.25%, from Data collection on the final assembling line OB91Z also note that the company can not achieve the expected production targets every day as many as 1500 kwh meter OB91Z type. Therefore the company needs to make improvements in the balancing path to reach their intended target in the final assembling line OB91Z. The method used is a heuristic method MALB (Mansoor Aided Line Balancing) and heuristic methods COMSOAL (Computer Method for Sequencing Operations for Assembly Lines). The data used is data on the production process of assembling the final line OB91Z and the amount of labor in assembling the final line OB91Z. After making improvements by using heuristic methods MALB (Mansoor Aided Line Balancing) then the balance delay becomes 14.62% and 85.38% effeciency be.

Abstract

This research has three objectives. The first objective is to develop a model of system dynamics of the production development of biodiesel as an alternative transportation energy source. The model is based on the National Model which was developed by Forrester. The second objective is to analyze the behavior of the model by using the policy instruments (depletion premium, loan interest, clean energy rules and sulfur tax) that support the effectiveness of the biodiesel production as an alternative transportation energy source. The third objective is to design the policy that support the effectiveness of the same system. The model has eight sub system: the biodiesel demand sub system in the transportation sector; biodiesel, Crude Jatropha Oil (CJO) and Jatropha curcas production sub system; population sub system; price sub system; capital goods sub system; petroleum income sub system; financial sub system; and government sub system. The model is then simulated in five policy scenario designs. The five scenarios were the ethanol production policy in year 2006 (basic model); the depletion premium fund raising percentage scenario; petroleum reserve raising scenario; price declining and production enlargement scenario; loan interest declining scenario. From the five scenarios, the best two scenarios were the petroleum reserve raising scenario and the price declining and production enlargement scenario. These two selected scenarios were then joined into two alternatives of policy that supported the effectiveness of the biodiesel production as an alternative transportation energy source. The first policy was the optimistic policy joining scenario and the second one was the pessimistic policy joining scenario.Keywords: System Dynamic, Biodiesel, Optimistic Policy, Pessimistic Policy.
