Abstract

The development in industrial world brings a big effect in management of company. Supply chain management is the best solution for increasing prime competitive, with target inventory of management between buyer and supplier. On conventional inventory of management, vendor calculates lot size production policy independently like that with buyer. Optimize of Economic Order Quantity’s vendor not same with Economic Order Quantity of buyer. This problem can finish if there negotiation or joint policy (Joint Economic Lot Size). The examination aims to determine optimal joint policy between buyer and vendor. Result of analysis the set of contract number 1 is optimal for vendor with first order quantity (Q1) = 4,481.02 ton, z1 = Rp 24,590,458.32 and second order quantity (Q2) = 1,542.29 ton and z2 = Rp 847,232 with bargaining the vendor’s expected bargaining surplus is given by Rp 19,251,181.95 so, with this contract buyer and vendor gets profit’s.

Abstract

Determining the best level of aggregation in a centralized supply chain is one of the most difficult problems because of the conflicting objectives and demand uncertainty. PT. Nampar Nos is one of leading drinking water company with various range market in some regions in Flores, even in some islands in East of Nusa Tenggara. It’s width service area and demand uncertainty. Causes the company has a good decision to decide where the warehouse should be located, and how much the optimal number of warehouses to satisfy the demand. This research uses bi-criteria model to determine the best distribution network between Warehouse and Demand Region. There are two steps in data process-ing that will be done. The first step is to determine the cost that relation with the old distri-bution network in Flores use Gaur and Ravindran model and the second step is to de-velop the new alternative use trial and error method and then calculate the total cost and also responsiveness. After the solver output, we get the best one configuration from 2 alternative configuration distribution network that is developed. Alternative 1 is the best configuration network amount warehouse and demand region which is yield in decreasing total cost per month about Rp 49.996.000 or 11% from level Rp 417.280.400 to Rp 367.284.400. And also decreasing product miles about 7.500 or 5% from 153.500 become 146.000.

Abstract

Madukismo is one of the companies operating in the area of agroindustry with sugar as the main product. In order to exist, the company needs to increase the work effectiveness and efficiency in using the production machines through the planning of maintenance scheduling in order that the machines or units that are going to be used can be operated well, and work properly.The aim of this research is to analyze level requirement of amount of spare-part optimal with Sparepart requirement nomograph approach. This effort is able to increase high production quality, availability and reliability by maximizing equipments age, and also exploiting of effective maintenance. Based on the research result shows that the maintenance of chain eye component, it should be differentiated, basically, on the maintenance time. Determination of feed amounts at "t" periods with level of protection equal to 95% depict amount of requirement of accesses for chain component that availed counted 30 units.

Abstract

PT. Jaya Pulau Bintan, Bangka is a company that produces rubber in the form of semi-finished materials. Companies experiencing difficulties in meeting consumer demand is continuous, because the rubber product manufacturing process is very complicated and time consuming. The research method used in addressing the problems the company is the method of scheduling a flow shop with the approach of theory of constraint in repetitive manufacturing systems make to order. The result of data processing by using 2 production scheduling system, namely FCFS scheduling with makespan yield of 18.96 days. While the TOC scheduling with makespan obtained by 16.02 days in order to obtain savings of 2.94 days. Scheduling production with the TOC proposed because it has a greater throughput and successfully utilize the resources constraints, especially at work stations more effectively and efficiently.

Abstract

Simply production system can be described as a relation usher the input element, process and input. The element have to be supported with the feed back to control the system produce that to be able to improve the continuous repair. PT. Barata Indonesia in the early year 2003 was doing program to improve of output by performing variously repair of the task department. From the repair result will be was done by a measurement with to compare with the production process previous period. In this research, the method used is function produce of the Cobb-Douglas by using of software SPSS analysis. From data processing result, got an equation of linear regression which have transformed into function produce the following Cobb Douglas: For the year of 2002 equation is Q = 90,92.I10,75.I40,53 and for the year of 2003 Q = 79,04.I10,66.I40,39. Based of the result analyze by using the function produce the Cobb-Douglas have given is Return to scale ( RTS) with the value 1,28 for the year of 2002 and 1,05 for the year of 2003. Because value RTS > 1 so this matter is inferential that production process of two period known of the Increasing to Scale, meaning that proportion of factors of production, such as input will be increase the production the larger ones. While for the calculation of elasticity given the following value: Year 2002 raw material elasticity = 0,75%, meaning each every addition 1% raw material by use of constant machine man hours, product become will increase 0,75%, for the elasticity of use of machine man hours = 0,53% meaning each every accretion 1% machine man hours by use constant raw material, will increase the product addition become equal to 0,53%. Year 2003 raw material elasticity = 0,66%, meaning each every addition 1% raw material by use of constant machine man hours, product become will increase 0,66%, for the elasticity of use of machine man hours = 0,39% meaning each every accretion 1% machine man hours by use constant raw material, will increase the product addition become equal to 0,39%.
