Abstract

PT Amanah Insanillahia is a Bottled Drinking Water (AMDK) company that has been operating for a long time and prioritizes quality as a company strategy. There are various criteria for problems faced by the company, including quality problems in the production of drinking water in 240 ml bottles. Six sigma can be defined as a methodology that provides tools to reduce process variations and improve product quality using the DMAIC (Define, Measure, Analyze, Improve, Control) method. The purpose of this research is to determine the company's current sigma level and provide suggestions for improvements that suit the company. From the research results it can be concluded that there are 3 potential CTQs, namely imperfect cup, lack of water and machine pinching, with an average (CL) defect of 0.320, and an average DPMO of 106,476. The sigma level value is 2,77. Then the next stage is carried out by analyzing the causes of the cup not meeting standards, lack of water and being pinched by the machine. It is known that defect factors come from machine, material, method and human factors.

Abstract

Penelitian ini bertujuan untuk mengidentifikasi pemborosan (waste) yang terjadi pada proses pencucian kendaraan menggunakan pendekatan lean service. Metode penelitian dilakukan dengan time study sebanyak lima kali percobaan, yang kemudian dipetakan menggunakan Value Stream Mapping (VSM) untuk mengetahui aktivitas bernilai tambah (VA), tidak bernilai tambah tetapi perlu (NNVA), serta tidak bernilai tambah (NVA). Hasil penelitian menunjukkan bahwa dari total cycle time sebesar 3207 detik, terdapat waste sebesar 333 detik (10,38%). Waste yang dominan muncul di antaranya adalah penggunaan slang dan water jet yang dipakai bergantian untuk motor, pengulangan lap eksterior–interior, multitasking kendaraan, hingga idle time akibat pegawai mengobrol. Setelah dilakukan analisis akar masalah menggunakan fishbone diagram dan five whys analysis, dirancang perbaikan berupa penerapan single-piece flow, penambahan SOP mikro, serta penyediaan alat kerja sesuai ergonomi. Implementasi simulasi perbaikan menunjukkan penurunan cycle time menjadi 2416 detik atau setara penghematan 791 detik (24,66%). Hasil ini membuktikan bahwa penerapan lean service dapat meningkatkan efisiensi waktu proses di layanan jasa pencucian kendaraan

Abstract

This study is motivated by the high consumption of cooking oil in the Micro, Small, and Medium Enterprises (MSMEs) sector, which is often constrained by operational costs, triggering the repeated use of waste cooking oil (jelantah) that poses carcinogenic health risks. This study aims to design and build a portable waste cooking oil filtration machine for households/MSMEs to provide a preventive solution to health risks while supporting economic efficiency. The research method uses a Participatory Ergonomics approach, involving active stakeholder participation including users, chemists, and manufacturing practitioners in identifying design needs. The design development results transformed the initial concept relying solely on gravity into an integrated four-stage purification system, namely: initial filtration using 100 mesh, heating process to reduce viscosity, water and odor absorption using zeolite adsorbent, and final filtration. The realization of the prototype with dimensions of 36 × 35 × 67 cm shows that this system is effective in separating solid contaminants, reducing water content and rancid odor, and producing visually clearer and usable oil. However, this study is limited to qualitative evaluation of oil clarity, odor, and water content reduction, and has not yet included quantitative laboratory analysis of free fatty acid levels.
