Abstract

In this paper, we consider a joint economic lot size (JELS) model consisting of single vendor single buyerwith single product. We intend to study the impact of defective items and controllable production rate onthe model. The demand in buyer side is assumed to be stochastic. The delivery of lot from vendor to buyer is conducted under equal size shipment and the lead time is assumed to be constant. The defective items founded by the inspector in buyer side are carried in buyer’s storage until the next shipment and will be returned to the vendor. The goal of the proposed model is to determine optimal delivery frequency, review period and production rate by minimizing the joint total cost. A sensitivity analysis is performed to show the impact of the changes of the decision variables on model’s behavior. The result from the sensitivity analysis shows that the joint total cost is sensitive to the changes of defect rate, demand uncertainty and demand rate.

Abstract

PT Fajar Indah is an automotive company which is one of their flagship products is muffler for Colt Diesel FE 120 PS. During 2012 and 2013, PT Fajar Indah was able to produced muffler up to 2400 unit with 6-7% defects rate. There are five type of defects that affects muffler’s quality which are lid’s defects, ring’s defects, defects of resonator’s size, defects of plate’s cutting size, and defects of broken plate. To determine whether improvements are needed in muffler’s prodution process and how they will be conducted so six sigma will be used for analysis. Analysis was conducted using DMAIC process, where recommended action for quality improvement were determined with RCA and FMEA. Result from analysis shows that PT Fajar Indah had 12,879 DPMO value and 3.73 sigma which mean that improvement is needed in muffler’s production process. Some recommended actions that can be done are maintenance scheduling, making work instruction and supervise it, improving storage method for ring’s model, provide place for plate scraps from cutting process, adding more workesr for products inspection, and looking for suppliers who are able to provide plate with standard quality.

Abstract

This study purposed the optimization of gaultherin production from “gandapura” by inactivating the gaultherase enzyme, including gaultherin productivity and process parameters. This research applied the combination processes of extraction-dryer, simultanously. The productivity of gaultherin was improved by adding the drying agent, such as magnesium sulfate, sodium sulfate, calcium chloride, and calcium sulfate. The optimization was conducted using a factorial design 2n. Dependent variables determined by calculating the main effects and interactions, following by the application of probability plots. During the research, the content of gaultherin, methyl salicylate, salicylic acid were measured by using a spectrophotometer and HPLC-MS. The results shows that the higher concentration of drying agent (especially calcium chloride) and ethanol, increased the content of gaultherin. However, the most influenced factor to this conducted process was pH, regarding to the concentration of ethanol. During extraction, the higher the pH, increased the active compound of gaultherin. The optimum condition of enzyme inactivation was found at pH 8 with the content of gaultherin at 14.46%. The higher the solvent concentration of ethanol, the higher content of gaultherin can be extracted. The maximum process condition regarding to ethanol concentration found at 90% with active compound concentration at 13.10%.

Abstract

Production activities which are conducted by some companies still use a lot of material inventory that production activities can run smoothly, but this condition is not considered optimal because many sources in the plant, so the investment is only in use for material. Ordering a material is not supported by data appropriately in product demand, it will make inventory of raw materials can not be sure so that the material is sometimes a lot and sometimes run out. The use of labor and production facilities are not accordance with demand, finally the production activities are not effective and efficient. Resources owned by the company must to be known in detail, so that the company can use capabilities of existing resources optimally. Company to achieve product demand should know the productive capacity, so that the ability of the company’s production targets can be achieved optimally, by measuring standard time at work operations and determine performance rating for each operator. In determining the demand for the product the next period using the method of linear regression forecasting the number of types of product demand of 1278 kg. Material requirements planning (MRP) orders can be made on day 7 of each month in accordance with the number of each type of raw material.
