XYZ is a company that produces plastic sacks and warings for local and foreign consumers (exports). This research was conducted at the Finishing Department, which carries out the process of cutting sack rolls into packaged products. There are three series of production processes, namely cutting, sewing, and packing. The process of cutting and sewing is done with the MOJ machine, namely MOJ-1, MOJ-2, and MOJ-3. The MOJ-3 engine is the engine that has the highest downtime, which is 409,68 hours. The downtime of the MOJ-3 machine caused the production process to stop because the sacks produced on the MOJ-3 machine could not be transferred to another machine. This research aims to impelement planned maintenance with determine the maintenance intervals to increase machine reliability. Maintenance intervals are specified for conveyor clip components, knife supports, and sewing loopers. The maintenance interval for clip conveyor components is 90 hours, knife support is 72 hours, and the sewing looper is 105 hours. The downtime of the clip conveyor component can be reduced to 19,41 hours, the knife support component to 8,55 hours, and the sewing looper component to 6,17 hours. The calculation results show that joint maintenance with a time interval of 105 hours can reduce the total maintenance cost from Rp207.963.924 (currently) to Rp91.808.815 (proposed). \u0000Abstrak. PT. XYZ merupakan perusahaan yang memproduksi karung plastik dan waring kepada distributor lokal dan konsumen luar negeri (ekspor). Penelitian ini dilakukan di Departemen Finishing yang melakukan proses pemotongan gulungan karung hingga menjadi produk yang telah dikemas. Terdapat tiga rangkaian proses produksi, yaitu pemotongan, penjahitan, dan pengepakan. Proses pemotongan dan penjahitan dilakukan dengan mesin MOJ, yaitu MOJ-1, MOJ-2 dan MOJ-3. Mesin MOJ-3 merupakan mesin yang memiliki downtime tertinggi, yaitu 409,68 jam. Downtime mesin MOJ-3 mengakibatkan proses produksi terhenti, karena karung yang diproduksi pada mesin MOJ-3 tidak dapat dipindahkan ke mesin lainnya. Penelitian ini bertujuan untuk menerapkan planned maintenance dengan menentukan interval pemeliharaan agar dapat meningkatkan keandalan mesin. Interval pemeliharaan ditentukan untuk tiga komponen kritis mesin MOJ-3, yaitu clip conveyor, penyangga pisau, dan looper jahit. Hasil perhitungan menunjukkan bahwa interval pemeliharaan komponen clip conveyor sebesar 90 jam, penyangga pisau sebesar 72 jam, dan looper jahit sebesar 105 jam. Dengan interval pemeliharaan yang dihasilkan, downtime komponen clip conveyor dapat direduksi menjadi 19,41 jam, komponen penyangga pisau menjadi 8,55 jam, dan komponen looper jahit menjadi 6,17 jam. Hasil perhitungan menunjukkan bahwa pemeliharaan bersama dengan interval waktu 105 jam mampu menurunkan total biaya pemeliharaan dari Rp207.963.924 (saat ini) menjadi Rp91.808.815 (usulan).","PeriodicalId":276819,"journal":{"name":"Jurnal Riset Teknik Industri","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134104397","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}

X is a company engaged in the leather industry that manufactures wallets, bags and key chains. The company experienced a decrease in sales volume due to a decrease in product quality from defective products in the company. Leather bags have an average percentage of disability of 2.39% in 2017-2018 from the company's disability limit of 2%. The existence of these defective products requires companies to improve product quality to reduce the occurrence of defects. The method used to solve the problems that are being faced by the company is the Seven Tools Quality Control method to identify the causes of product defects, while the Rezhenija Izobretatelskih Zadach (TRIZ) method is used to design a product quality improvement plan. The result of data processing which becomes the main priority is defect cutting. The causes of cutting defects include decreased work concentration, inadequate workers, poor physical condition, no machine maintenance, blunt cutting machines, high cutting machine use intensity, work environment, hot room temperature, lack of work space lighting. All causes of product defects are designed to improve the quality of leather bag products by creating visual controls, forms for worker health, cutting knife replacement machines, installing air conditioners, and adding lights to the sewing machine. \u0000Abstrak.

The fabrication process of a sarong product is carried out with a semi-automatic machine that is operated by an operator with some process elements that are carried out by a conventional operator. Based on the identification of work risks using the Quick Exposure Checklist (QEC) questionnaire, that operator works in a limited body posture condition so as to produce a score of more than 50% and the need for action in the near future. These results indicate how high this risks experienced by finishing work station operators. The condition of the operator working in a folded or squatting sitting position, forearm reach, dynamic hand movements plus limited operator motion because sitting without proper facilities is a major problem. If this is not treated as soon as possible it can have a negative impact on the operator such as physical fatigue, decreased operator performance to skeletal muscle injury (mosquletal disorder). Quick Exposure Checklist show that the occupational risk level of work is at level 3 (three) which shown a high score level that action is needed as soon as possible to minimize the risk of work.
