Abstract

The article presents the Biased Random Key Genetic Algorithm-Population Degradation (BRKGA-PD) design for completing Capacitated Closed Vehicle Routing Problem with Time Windows (CCVRPTW) on soft drink distributions that have been studied by Sembiring (2008). The goal is to determine some closed routes in meeting consumer demand with time limits and limit the capacity of vehicles used, so the total cost of distribution is minimal. The proposed algorithm adopts the extinction of population size. BRKGA-PD is coded using Matlab programming with the best parameter setting. The resulting solution is a subrute with a minimum of distribution fee. This algorithm is compared with two other methods, namely BRKGA general and heuristic methods. The results of this study can be concluded that the BRKGA-PD method is able to improve the general BRKGA because with a time difference that is not significant can provide cost savings of Rp. 6.857,- and BRKGA-PD is better than heuristic method because it can save more cost Rp. 87.000,-.

Abstract

The quality of product is reflected from the performance of its process. The most frequent issue that occurs in local company today -- is -- most company only focuses on the output regardless the process. It causes the difficulty that occurs in local company to compete with other company in global environment. One of the local companies that has their business shifting up significantly, with the great number of export target and actual export, is PT Dharma Medipro, which has many processes on the production of sphygmomanometer. One of the processes that critical to quality is latex dipping process, where the yield of this process that must be considered is the thickness of the bag component. In order to improve the process, we should first establish the measurement of process performance using capability process technique, which is one of the tools came from statistical process control method. The result indicates that the process is unstable with the value of capability indices Cp = 4,69 ; Cpk = -0,77 ; Cpu = -0,77 ; Cpl = 10,15 ; and Cpm = 0,28, moreover the number of part per million (PPM) that out of the spesification limit reach 912.500 units.

Abstract

Lemuru fisheries in Bali strait, Muncar, Banyuwangi has strategic role for fish canning industries. Sardinella lemuru has low economic value as fresh fish but high as fish canning. Fisheres production system must be viewed as a whole value added system, starting from landing site at fisheries port to fish processing industries and distributed to the consumers. Lemuru from Muncar fishery port are distributed to canning industries, cold storage, flour and fish oil industries. This research aims to (1) describe fish distribution pattern from landing site to industries, (2) determine fish processing cost in industries, (3) determine the economic added value of lemuru as various products. Data collection method are interview with fisher and industries, direct observation and secondary data from research report and scientific publication. Cost in fish processing industries is classified as investment cost, operating cost and overhead cost. The totalcost will becompared to the product price, from which the differenceis theadded value.  Value-added creation also considers the conversion rate between fresh fish products into finished products. Research  shows that, among the fish processing industries under consideration, canning industry has highest added value in the amount of USD 3.5 million/ton of finished product. For the canning industry, every 1 ton of fish can equal be converted to 1,5 ton of canned fish products. Flour and fish oil industry, in the meantime, generates added value of Rp 2.3million/ton. Finally, cold storage industry has lowest added value of 1.8 million/ton of product. Cold storage industry produces frozen fish and has a function for storing fish production in the harvest season.

Abstract

CV Poetra Mandiri Karton is a company that has not been able to meet production target each day.  Based on preliminary analysis, production underproduction was due to workers’ fatigue caused by manual material handling activities in the entire production process.  To solve these problems, nordic body map (NBM) approach was applied.  Prior to work, workers experienced musculoskeletal fatigue at down waist, and they experienced musculoskeletal fatigue at up waist, left forearm, right forearm, left hand, right hand, left ankle, and right ankle after work. Based on questionnaire of National Aeronautics and Space Administration Task Load Index (NASA-TLX), average of mental workload from all three groups is quite heavy.  By using rapid entire body assessment (REBA), it is found that average value of the risk in group 1 and group 2 requires immediate action, whereas action is required by the third group.  This article also presents a trolley design that will be used in manual material handling activities.

Abstract

The article identifies the criteria for choosing a trade show and develops a basic model of exhibition selection for creative industry players before deciding to participate in a trade show. It is necessary to ensure that expenses in terms of business, money, and time, will be worth the results. Based on literature review and interviews, six criteria were used, namely location, booth position, organizational reputation, cost estimation, prestige, and reputation of other participants. After selection criteria are identified, then calculations are performed to measure the criteria weight by using the AHP approach. Based on weight calculations, it was found that booth positions had the highest importance weight, followed by trade show location, organizers reputation, cost estimation, prestige and reputation of other participants. The weight value is then used to calculate the trade shows prediction value. The predicted value generated from the model is then compared to the value of the past data. The model has an accuracy rate of 89% and does not have a significant difference between the value generated by the model and the value of the past data.
