Abstract

PT XYZ adalah salah satu industri pemasok Fast Manufacturing Customer Goods yang memproduksi backsheet diapers dimana menghasilkan emisi dan waste pada siklus produksi. Berdasarkan penelitian sebelumnya, proses produksi belum efisien. Terdapat waste dan downtime yang tinggi ditemukan dalam proses produksi, banyaknya cacat sama dengan waste produksi. Penelitian ini bertujuan untuk meningkatkan efisiensi produksi dan memperbaiki dampak lingkungan yang mempertimbangkan lean and green pada saat yang sama. Value Stream Mapping digunakan untuk identifikasi aktivitas-aktivitas yang tidak perlu. Identifikasi waste kritis dilakukan dengan Metode Count Borda. Waste kritis dalam setiap proses produksi adalah cacat/defect. Hasil penilaian dampak lingkungan dengan metode Life Cycle Assessment yang menggunakan software SimaPro adalah 115 kPt. Proses extruder menunjukkan dampak lingkungan tertinggi dikarenakan penggunaan material polyethylene low density granulate (PE-LLD). Dampak kategori tertinggi adalah fossil fuels, respiratory inorganic, dan carcinogens. Terdapat 3 alternatif perbaikan yaitu alternatif perbaikan 1 adalah penggunaan recycle dari waste extruder sebesar 10,18%; alternatif perbaikan 2 adalah penggunaan recycle dari waste extruder dan slitting sebesar 16,5%; dan alternatif perbaikan 3 adalah perubahan komposisi material dan penataan ulang WIP (blank middle roll dan printed middle roll). Berdasarkan target perusahaan untuk meningkatkan efisiensi dan mengurangi dampak lingkungan, alternatif yang dipilih adalah alternatif perbaikan ketiga. ====================================================================================================== PT XYZ is one of supplier Fast Manufacturing Customer Goods backsheet diapers that produces emmision and wastes along cycle of production. Based on previous research, the process production performance is inefficient. It is found various wastes and downtime, defect product as well as wasted production. This research aims to improve the production efficiency and to be environmental friendly that’s taking into account lean and green at the same time. To do so, Value Stream Mapping is utilized to identify the wasted activities. Identification of critical waste is performed by Borda Count Method. The critical waste in each production process is defect. The results of the environmental impact assessment with LCA method use software SimaPro is 115 kPt. Extruder process shows the highest environment impact because using materials from polyethylene low density granulate (PE-LLD). The highest category impact is fossil fuels, respiratory inorganics, and carcinogens. There are alternative improvements: the first is use recycle from waste extruder 10.18%; second are use recycle from waste extruder and slitting 16.5%; and third is changing material composition and re-layout of work in process (blank middle roll and printed middle roll). From quality and efficiency sides, selected alternative improvement is changing materials composition by increasing LLDPE portion in formula. Based on the company's target to improve efficiency and reduce environmental impacts, the selected alternative is the third improvement alternatives.
