Z, which is engaged in palm oil processing. The case raised is the spare parts warehouse of PT. Z, where the problem that has occurred so far is the policy of random storage in the spare parts warehouse. This results in irregularities that complicate the process of receiving, storing, searching and releasing spare parts, which is indicated by the high total travel distance in the warehouse. Thus, the purpose of this study is to minimize the total travel distance in the spare parts warehouse by using a dedicated storage policy which is based on an analysis of the product storage layout (spare parts). Based on the results of data processing using a dedicated storage policy, the initial trip distance is 4257.25 meters and the proposed trip distance is 4002,5 meters. From these conditions, it can be concluded that using a dedicated storage policy can reduce the total travel distance in the spare parts warehouse by 254,75 meters or around 5,9%.","PeriodicalId":32888,"journal":{"name":"Jurnal Rekayasa Sistem Industri","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84476361","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}

Service quality is a determining factor in satisfying customers to achieve economic improvement. Based on previous research, it was found that there is a relationship between organizational culture and customer satisfaction. The quality culture in a laboratory organization reflects the overall organizational culture. This is in line with the ISO/IEC 17025:2017 which requires the application of a quality culture in a calibration laboratory. Price is also an element that needs to be analyzed to achieve customer satisfaction in a calibration laboratory. This study aims to analyze the effect of service quality on customer satisfaction by moderating organizational culture and prices in an ISO/IEC 17025:2017 accredited laboratory in the province of West Sumatra. The data was collected by distributing questionnaires to 93 respondents from government agencies and private companies in West Sumatra. Then, the data was processed using the method of Partial Least Square-Structural Equation Modeling (PLS-SEM). The results of this study indicate that service quality, organizational culture, and price have a positive and significant effect on customer satisfaction in a calibration laboratory. Moderation of organizational culture and price have no significant effect on the relationship of service quality to customer satisfaction in a calibration laboratory.","PeriodicalId":32888,"journal":{"name":"Jurnal Rekayasa Sistem Industri","volume":"65 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87295783","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}

Pemerintah telah memiliki beberapa alternatif solusi dalam pengelolaan sampah, seperti pembuatan bank sampah, rumah kompos, pemaksimalam program 3R (reduce, reuse, dan recycle), dan pemanfaatan sampah sebagai sumber energi. Penelitian pemanfaatan limbah plasik PP untuk pembuatan cone benang daur ulang juga termasuk dalam pemanfaatan program 3R yang diwacanakan oleh pemerintah. Tujuan penelitian ini adalah untuk mendapatkan karakteristik mekanis (kekuatan flexural) dan massa cone benang berbahan PP daur ulang dan PP murni. Berdasarkan observasi yang telah dilakukan, produk cone dengan material PP memiliki karakteristik kekuatan lentur 0,4 – 0,8 kg/mm2 dan massa sebesar 10,5 – 11,5 gram. Studi pemanfaatan limbah plastik PP untuk dijadikan produk cone benang diawali dengan penelitian awal terkait dengan pengoptimalan parameter pembuatan produk pada mesin injeksi. Proses selanjutnya adalah pembuatan produk cone benang dengan ditambahkan material kalsium. Setelah produk selesai dicetak, langkah berikutnya adalah pengujian flexural dan pengukuran massa produk. Berdasarkan pengujian flexural dan pengukuran massa produk, material PP Murni yang ditambahkan material kalsium karbonat 20% memiliki kekuatan flexural yang lebih baik, tetapi massa yang dihasilkan tidak sesuai dengan ketentuan, yaitu 12,30 gram.

Minimizing milling process-cost is one of the most common optimization objectives, and thus it determines the best cutting tool to be used. However, the chosen cutting tool might not bring the optimal result based on the tool’s cost. Therefore, a valuation method based on the process and cutting-tool costs results were developed and analyzed to improve the cutting tool selection process.  A specific rough-milling operation was entered to the quick cost-estimation and optimization application, and several cutting-tools were compared based on the process-cost by each tool. Using a weight-based analysis on both process-cost and tool-cost changes the cutting-tool options' initial rankings. This study showed that using different weight ratios altered the order of the most suitable cutting tools. Another finding revealed in this study is how deflection constraint affected the rank of cutting tool selection. Thus, knowing the proper limit of deflection is crucial to validate the cutting tool selection outcome.","PeriodicalId":32888,"journal":{"name":"Jurnal Rekayasa Sistem Industri","volume":"47 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-04-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75349568","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}
