Perancangan lean sustainable manufacturing dan usulan strategi 3r pada PT.Gs Battery
P PT.GS Battery merupakan salah satu anak perusahaan dari Astra Otoparts yangmenghasilkan produk berupa aki kendaraan bermotor Permasalahan yang dimilikiperusahaan saat ini adalah adanya pemborosan (waste) yang terdapat pada prosesproduksi yang menyebabkan perusahaan tidak dapat mencapai target produksi sertaadanya resiko kecelakaan kerja dan banyaknya limbah yang dihasilkan melaluiproses produksi. Tujuan dari penelitian ini adalah untuk meminimasi waste yangterdapat pada proses produksi serta memberikan usulan strategi 3R(Reduce,Reuse,Recycle) menggunakan pendekatan Lean SustainableManufacturing. Penelitian ini difokuskan pada produk MCB MF yang memilikipermintaan paling tinggi sebanyak 69%. Tahap awal penelitian ini adalahmelakukan pengukuran sustainability awareness, drivers, barriers dan benefitsmenggunakan kuesioner. Dilanjutkan dengan analisa waste menggunakanSustainable Value Stream Mapping untuk mengetahui nilai Value Added,Necessary Non Value Added, Non Value Added Activities. Kemudian dilanjutkandengan analisa penyebab terjadinya waste menggunakan diagram ishikawa dananalisa penerapan 3R pada proses produksi. Melalui hasil analisa diketahui bahwaterdapat waste transportation, defect, waiting dan inapropriate processing ,saat iniperusahaan juga sudah menerapkan strategi reuse dan recycle pada prosesproduksinya. Tahap selanjutnya adalah menghitung nilai kepentingan untuk setiappilar sustainability menggunakan Pairwise Exchange Method dan melakukanperhitungan sustainability index. Melalui hasil perhitungan diketahui bahwa saatini perusahaan memiliki nilai sustainability index sebesar 144,35%. Hasil yangdiperoleh melalui penelitian ini adalah usulan strategi reduce untuk mengurangilimbah yang dihasilkan dan penggunaan bahan baku timah serta strategi recyclepada limbah container aki hasil proses produksi. Terdapat penambahan nilaiProcess Cycle Efficiency sebanyak 0,44% melalui usulan perbaikan dan terdapatperbaikan nilai Sustainability Index sebesar 9,70% yang semula adalah 144,35%menjadi 134,65%.
P PT. GS Battery is a subsidiary of Astra Otoparts which produces products in theform of motor vehicle batteries. The problem that the company currently has is thewaste contained in the production process which causes the company to be unableto achieve production targets and the risk of work accidents and the amount of wastegenerated through the production process. The purpose of this research is tominimize the waste contained in the production process and to propose a 3Rstrategy (Reduce, Reuse, Recycle) using a Lean Sustainable Manufacturingapproach. This research is focused on MCB MF products which have the highestdemand as much as 69%. The initial stage of this research is to measuresustainability awareness, drivers, barriers and benefits using a questionnaire.Followed by waste analysis using Sustainable Value Stream Mapping to determinethe value of Value Added, Necessary Non Value Added, Non Value AddedActivities. Then proceed with analysis of the causes of waste using Ishikawadiagrams and analysis of the application of 3R in the production process. Throughthe results of the analysis, it is known that there is waste transportation, defect,waiting and inappropriate processing, currently the company has also implementeda reuse and recycle strategy in its production process. The next step is to calculatethe importance value for each sustainability pillar using the Pairwise ExchangeMethod and calculate the sustainability index. Through the calculation results, it isknown that currently the company has a sustainability index value of 144.35%. Theresults obtained through this research are the proposed reduce strategy to reduce thewaste generated and the use of tin raw materials as well as a recycle strategy for thewaste battery container produced in the production process. There is an increase inthe value of the Process Cycle Efficiency of 0.44% through proposed improvementsand there is an improvement in the Sustainability Index value of 9.70% from144.35% to 134.65%.
