Abstract

Abstrak—CV XYZ adalah perusahaan manufaktur yangmemproduksi spare part mesin industri. Dalam prosesproduksinya, pada lini produksi nozle wafer stick menunjukkanadanya ketidaktercapaian target produksi. Salah satu faktorpenyebab permasalahan tersebut adalah adanya kerusakanatau downtime pada mesin turret milling. Downtime yang terjadisebesar 7552 menit. Sebab terjadinya downtime adalah terdapatkomponen mesin yang mengalami kerusakan, dengan frekuensitertinggi pada end milling. Oleh karena itu, dilakukanperhitungan nilai efektivitas penggunaan mesin denganmenggunakan metode OEE (Overall Equipment Effectiveness).Hasil kondisi aktual sebesar 62% dan target standarinternasional sebesar 85%. Hal ini menunjukkan performamesin yang rendah dan butuh dilakukan tindakan maintenance.Ketidaktercapaian nilai OEE tersebut dianalisis denganmenggunakan metode six big losses dan ditemukan kerugianterbesar terdapat pada reduce speed losses sebesar 29%.Dilakukan tindakan dengan penerapan metode TotalProductive Maintenance (TPM) dengan penerapan autonomousmaintenance melalui pemeliharaan kondisi mesin menggunakancheck sheet berstandar Cleaning Lubricating, Inspection, danTightening (CLIT) dan penerapan planned maintenance melaluipembuatan penjadwalan. Dilakukan perhitungan denganmetode age replacement, sehingga diperoleh hasil rancanganpenjadwalan dengan waktu pemeriksaan dan penggantiankomponen mesin setiap 111 jam & 180 jam. Berdasarkan nilaiavailability yang diperoleh dari perhitungan menggunakan agereplacement sebesar 98.78%. Kata kunci— OEE, Six Big Losses, TPM, Age Replacement

Abstract

Abstrak — PT XYZ merupakan perusahaan fashion yangmemproduksi kaos kaki mengalami permasalahan tingginyatingkat defect pada produk kaos kaki jempol selama periodeJuni hingga November 2023. Meskipun permintaan tinggi, rataratadefect rate mencapai 4.04%, melampaui batas toleransiperusahaan sebesar 3%. Dari enam tahap produksi kaos kaki,yaitu rajut, obras, bolak-balik, oven, sortir, dan pengemasan,terdapat beberapa jenis defect, seperti lubang, noda, turun size,belang, dan bahan baku. Analisis Pareto menunjukkan bahwajenis defect yang paling dominan adalah lubang, dengan tingkatdefect sebesar 33% yang berasal dari proses rajut. Berdasarkanmasalah tersebut, dilakukan analisis tahap-tahap pada prosesrajut menggunakan analisis Failure Mode and Effect Analysis(FMEA). Mode kegagalan dengan nilai Risk Priority Number(RPN) tertinggi adalah jarum rusak sebesar 392 dan jarumpatah sebesar 336. Untuk merancang solusi dari permasalahanyang ada, digunakan metode poka yoke yang bertujuanmencegah cacat produk. Usulan perbaikan meliputipenggantian jarum secara serentak sesuai umur pakainya,dibantu oleh alat sensor alarm. Alat ini dirancang untukmengatasi masalah pada penggunaan jarum yang tidak digantisaat umur pakainya telah habis. Alat ini dirancang untukmendeteksi dini dan mencegah kegagalan sehingga kualitasproduk dapat ditingkatkan dan defect yang disebabkan olehjarum pada mesin rajut dapat dikurangi. Kata kunci — Lean Manufacturing, defect, FMEA, poka yoke, sensor

Abstract

Abstract-This research focus on reducing total tardiness on single-stage identical parallel machine in PT XYZ. The method used are EDD rules where the job is sorted based on earliest due date and job splitting property where the job is split between the machine with maximum tardiness and the machine with minimum tardiness. The proposed method managed to yield successful result by decreasing the total tardiness up to 33%. Keywords- identical parallel machine scheduling, EDD, job splitting property

Abstract

PT Grow Commerce Indonesia is a technologydriven company which focuses on the digital branding ofpartner brands, mostly local brands. They also help in thewarehouse and distribution activities of the partner brand’sproducts. The warehouses that are used by Grow Commerce arethe partner brands. The problem faced by PT. Grow CommerceIndonesia is that each year, their warehouse always hasoverstock left, with increase of quantity each year. The authorintends to analyze the problem and design a solution using theNewsvendor Model. The Newsvendor model helps indetermining the optimum quantity of products that should bemanufactured/ordered to avoid overstocking (supply is morethan demand) and or understocking (demand is more thansupply) which overall avoids the loss of profit. By analyzing theforecast of demands, the Newsvendor model can calculate theoptimum number of stocks to minimize loss of profit. Keywords— PT. Grow Commerce Indonesia, Overstock,Newsvendor Model

Abstract

Indonesia as the world's archipelagic country haveIndonesia have almost 3,8 million hectares of coconut plant. Thatlead Indonesia to one of the biggest countries in exporting thecoconut product. One of the products that has been exported isdesiccated coconut. The interest of desiccated coconut isincreasing in several countries. CV Una Surya Putra Mandiri isone of the that producing the desiccated coconut. This companyuse the principle of make to stock because of the raw material thatwas easy to be spoiled. Due to the uncertainty of the demandfluctuations, the company was struggling in producing the rightyamount of product. So, the production of the company mostly getoverproduction that cause the overstock in inventory while theproduction must go on. Based on the problem occur, this researchhas an objective to minimize the overproduction and backorder. Inminimized the production cost, they are needing a productionplanning. In the other word, production planning will bedetermined the forecasting demand, the resource availability, andthe schedule to fulfil the demand. The output in this research isfinding the minimum production cost using the plannedproduction to fulfil the demand Keywords: Production Planning, Demand Forecasting, RoughCut Capacity Planning, Scheduling, Uncontrolled Production
