The obstacle faced in producing the 428H Chain is not achieving the production target from June to July, and September to November 2021. The research focuses on minimizing manufacturing lead time using lean manufacturing by eliminating waste in the 428H Chain production process. Waste elimination is done by providing suggestions for improvements based on the identified waste types. The study begins with the calculation of the time sample, then MLT, PCE, the use of the Waste Assessment Model, and mapping current value stream mapping. The initial MLT was 832.95 minutes and PCE was 63.37%. WAM produces the highest percentage of waste in the type of defect, then motion, inventory, waiting, overproduction, motion, and process. The proposed improvements are in the form of designing SOP Operators on Pressing machines, adding Small Incline Belt Conveyor tools, designing SOPs for Activities in the WIP Area, and adding Manual Hand Stacker tools. The provision of improvement proposals resulted in MLT decreasing 12% to 733.2174 minutes and PCE increasing 8.6% to 71.98%, and the production target was achieved with total production per month increasing by 12%, from 21,783 to 24,746 units per month.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43592243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The drying process usually carried out by farmers is drying directly in the sun, and the smoking process uses fire to heat. The method of drying the areca nuts takes about 14-15 days. This study will examine the problems faced by farmers in the process of drying areca nuts. Based on the issue of drying areca nuts, it is necessary to have an alternative method of drying that is more efficient. Areca nut drying machine is an alternative to obtain dried betel nut relatively quickly with well-maintained fruit quality. The design of the areca nut drying machine is made based on the identification of farmers' needs. Identifying farmers' needs or desires will be an attribute of product development, and technical parameters are determined to meet these product attributes. The method that will be used is the Quality Function Deployment (QFD) method. The study results that priority attributes must be completed based on calculations in the planning matrix using QFD. The design of the areca nut has dimensions of 260 mm x 490 mm, with the specifications of the tool consisting of two main parts, namely an inner filter (a place for betel nuts) and a betel nut dryer.","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49144642","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This non-ergonomic condition was identified by using the Nordic Body Map questionnaire to find out complaints on 28 body parts of three operators. From the identification of weaving operators using a nordic body map, it is known that there are complaints on the back, waist, and hips of the body. Identification using the Rapid Entire Body Assessment method shows that the final result of the assessment is 11, which means that there is a need for improvement now on the operator's work posture. The results of the QEC method show an exposure score of 97.12% for operator 3 and the action that must be taken is research and changes now. To reduce the risk of high work posture, a proposal for improving the working posture of the weaving machine set up operator was formulated by designing a manual scissor lift tool. In the process of designing tools, Indonesian anthropometric data is needed. The stages of designing tools are identifying operator needs, conceptualizing tools using a need metric matrix, selecting tools concepts with combination tables and scoring concepts and describing the design of tools using AutoCAD and CATIA software. From the results of the selection of several alternative concepts, a tool in the form of a manual scissor lift was chosen which has a combination of elements, namely a square working platform design, using 2 hydraulics and raw materials made of steel. Meanwhile, the manual scissor lift specification has a maximum height of 85 cm, a footing length of 70 cm and a footing width of 46 cm. It is known that before the proposed improvement, the final result of the REBA score was 11 and after the improvement the final result of the REBA score was 4 which indicates that the operator's work posture has improved after using the assistive device, especially in the arms, legs and back of the operator","PeriodicalId":34167,"journal":{"name":"OPSI","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49196328","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The analysis process used is the Fault Tree Analysis (FTA) method because of its efficiency. Based on the results of the FTA, it was found that the basic event in the case of overstock material and deadstock material, namely changes in skincare trends in the community that caused very significant changes in the results of purchase orders and forecasts. The solution for the problem of overstock material and material deadstock is the application of a stock level system on inventory. Meanwhile, in the Outstanding material case, 3 basic events were obtained including, long lead time for delivery by overseas suppliers, trouble machines and many rejected quality items.
