Abstract

Abstract Adi Bungsu (AB) Cigarette Company produces Clove Cigarette in four stages. Each stage is processed by one machine. Thus, the production line is described as flowshop. AB receive order from customer over country. Every month, AB should schedule the order from customer. Thus, AB should prioritize which order to be processed firstly. At this time, AB schedules their order by using First Come First Serve algorithm which prioritize the first order as the first processed job. Previously, this algorithm results in tardiness and high work-in-process. Therefore, this study aims to reduce the tardiness and work-in-process level. In this study, the scheduling problem is solved by using mixed integer programming. To minimize tardiness and work-in-process simultaneously, the objective include minimizing total tardiness and total flowtime. Meanwhile, this study also consider setup time separated from processing time so that setup can be done early while waiting job to be processed in previous stage. The results of this study show that mixed integer programming with two-criteria can be used to schedule job ordered by customer. In case of bicriteria scheduling problem with separated setup time, mixed integer programming generate better schedule than FCFS algorithm.

Abstract

Abstract The effort of searching about cheaper fuel alternative and environment friendly was solution for problem in rare fuel. This paper examine potential energy from renewable source. Design in reactor with 16m3 capacity for retain feces from 200 human. Based on calculation from the design, this reactor can produce biogas about 4m3/day. Air methane affected by ratio input of C/N (human fecess), time of residence, pH, temperature, and toxicity. Digester temperature about 25–27oC and pH 7–7,8 produced biogas with composition of methane air about 77%. For using this gas we need level of pressure 4 mm H2O and biogas level at 0.23 m3/hour. Beside this if we want for household activities for example cooking we need biogas 0.30 m3/hour with level pressure at  75 mmH2O. The analysis for effect on environment from mud that produced from reactor shown decreasing at COD about 90% from  new material condition. The comparing of  BOD/COD about  0,37 smaller than normal condition from liquid waste that have BOD/COD=0,5. And the other benefit we get analysis of composition N, P dan K shown same result that we get at fertilizer.

Abstract

Abstract Productivity improvement of the company can be reach with many effort, which are minimizing waste, improving the utility of operator, and also redesigning layout facilities. Based on the observation, idle time of operator for the injection process is 30 minutes. If the delay will be compare with the company losses, it is equal to IDR. 1.001.700/operator/month. Based on this problem, redesign of the facilities layout is a solution to improve utilities and workload of operator. The result of this research, alternative layout has design based on simulation and the analysis of Activity Relationship Chart (ARC). It could be minimized the material handling 49.4 meters and 42.9 seconds. For the financial analysis, it can be minimized the labour cost IDR 14.684.670/month and also the material handling cost at least IDR 54.262/month.

Abstract

ABSTRACT  Productivity garment greatly influenced by the work station facilities and presence in the workplace. UD Aliya- Malang is one example as an object of research. Based on the results of the initial surveys and interviews conducted by the operator, there are a number of complaints were found among them is the problem of the narrow room, the buildup of working materials at the work station, lighting and air circulation is less to make the operator comfortable in work. Based on the results of measurements, conditions of work station at UD Aliya still less ergonomic, which if left unchecked can lead to many complaints and problems in the future. Improvement of  work station using Ergonomic Environment approach, the results can be obtained using the optimal amount of light for each work station, a reduction in noise levels, and improved air circulation using venilator turbine. As well as using ARC analysis, the results obtained are placement work station layout, the result is important juxtapose work station I and IV with the Warehouse. Keywords: Work Station, Activity Relationship Diagram, Environment Ergonomic

Abstract

ABSTRACT  Productivity garment greatly influenced by the work station facilities and presence in the workplace . UD Aliya -  Malang is one example as an object of research . Based on the research conducted , there are still some problems . This is also supported by the operator of complaints about the draft working facilities , the work table is often used as a medium to carry out the activity of cutting material (cloth or canvas). Incompatibility between the dimension table with the body dimensions of operators resulted in operators often complain , and perform movements beyond the normal limits . By using anthropometric approach , the results obtained is the size of the table corresponding to the dimensions of the body of the operator , namely the size of the table is 117cm x 69cm x 98,41cm . Keywords: Work Station, Facilities of Work, Anthropometry

Abstract

Abstract Quality is one of problems commonly happen in production. It can be vary and affect the level of product quality and service. Improving quality is needed to keep a good quality of a product. X Inc is one of a company focus on making slipper. The problem is facing by the company is that the method use to decrease the defect and waste is not effective yet. Based on the problem above, a researcher conduct a research and basic concept development lean six sigma to improve the quality by integrating FMEA and AHP in identifying the product defect. It is hoped that the X inc. can keep or maintain and improve the quality in order to fulfill the costumer`s need. Based on the result of FMEA-AHP computation, it is found that IR result is 0,0745. It means that the data is consistent. While priority FMEA-AHP computation for each criteria will be used as reference in making or taking decision. Keywords : lean six sigma approachment, FMEA-AHP, defect, slipper.

Abstract

Abstract. The aim of this paper is to assess and evaluate the environmental impact during the manufacturing process of Liquid Cristal Display (LCD) monitor of personal computer.  Life cycle assessment  (LCA) is utilized to evaluate the environmental impact during the manufacturing of LCD.  The environmental load is expressed by Eco indicator 99 method.   The damage categories based on Eco Indicator 99 consist of 11 categories, carcinogenic, respiratory inorganic, climate change, ionizing radiation, ozone layer depletion, Eco toxicity acidification/eutrophication, land use, extraction of mineral, and extraction of fossil fuels. Furthermore the environmental load is divided by  three categories, which are human health, damage of ecosystem and depletion of resources. Simapro software version 8 is applied to calculate the environmental load each component of LCD display personal computer product. Finally, the result showed that the largest environmental load during the manufacturing process of a LCD computer display is to human health, followed by damage of ecosystem and the depletion of resources. Also, PWB component part of LCD monitor has the largest contributor for degradation environmental performance during the manufacturing process of monitor LCD, following by production of metal and plastic.

Abstract

IKM genteng Talangsuko is a roof tile producers that was founded in 1980. They can produce 300-350 roof tile in each day. However, the accumulation of material happens frequently due to the limited capacity of drying space. This problem causes the production process to be obstructed, so they need an equipment that can increase the production capacity of the roof tile. Accordingly, the purpose of this research are to determine the design and spesification of the equipment and to determine whether the equipment could increase the production capacity of roof tile. This rearch proposes design of the equipment using the AHOQ method. The result of this research is the specification of the equipment that consist of three components which are rack body, wheels, and the last part is slope arranger for each level of rack. The design of material handling equipment is in the form of multilevel racks with wheels. This equipment may increase the production capacity of roof tile in IKM Genteng Talangsuko especially for the drying process to 2 times from 300-350 to ± 750 roof tiles.
