Electronic Theses and Dissertation

PT M Jusuf & Sons merupakan perusahaan distributor yang mendistribusikan produk bermerk Coca-Cola dan serta produk lainnya dari perusahaan Coca-Cola Amatil Indonesia (CCAI). Perusahaan ini memiliki gudang persediaan yang terletak di Banda Aceh. Alur proses pergudangan yang ada di gudang ini terdiri dari pemeriksaan dokumen pemesanan, pengambilan palet, palletizing & sortasi, pekerja membawa barang ke gudang, menyusun barang di palet, pekerja jalan dari palet ke truk, pendataan, pembuatan nota pemesanan, pemeriksaan nota pemesanan, pengambilan palet, order picking, dan proses menyusun pesanan di dalam truk. Dikarenakan lead time proses membutuhkan waktu yang lama, maka dilakukan perampingan pada proses pergudangan menggunakan pendekatan lean warehousing. Tools yang digunakan pada penelitian ini adalah Value Stream Mapping (VSM) untuk memetakan seluruh proses dan waktu manajemen pergudangan, serta menganalisis aktivitas yang bersifat Value Added (VA), Non Value Added (NVA), dan Necessary Non Value Added (NNVA). Dari hasil Current State Map (CSM), didapatkan total lead time sebesar 554,016 menit, dengan waktu VA sebesar 303,773 menit, dan NVA sebesar 250,243 menit. Selanjutnya dilakukan pembuatan rancangan perbaikan digambarkan pada Future State Map (FSM) berdasarkan pengurangan seven waste. Hasil menunjukkan adanya pengurangan total lead time menjadi 494,666 menit, dengan VA menjadi 303,774 menit, dan NVA menjadi 190,892 menit. Waste yang paling banyak terjadi yaitu waiting dan unnecessary motion. Selanjutnya dilakukan usulan perbaikan berdasarkan VSM, yaitu relayout gudang dari hasil perhitungan ABC analysis dengan penempatan produk berdasarkan kelas A, B, dan C. Hasil produk dengan kelas A tertinggi adalah produk 390 PET X12 SPRITE CLR P5500.

PT M Jusuf & Sons is a distributor company that distributes Coca-Cola branded products and others from the Coca-Cola Amatil Indonesia (CCAI) company. This company has a warehouse located in Banda Aceh. The warehousing processes in this warehouse consist of checking an order document, pallet taking, palletizing & sortation, workers bringing products to the warehouse, arranging products on pallets, workers walking from pallet to truck, data collection, making an order note, checking an order note, pallet taking, order picking, and putting down the order to the pickup truck. Because the lead time of the process takes a long time, the warehousing process will be streamlined using a lean warehousing approach. The tools used in this research are Value Stream Mapping (VSM) to map the entire time warehousing management process as well as to analyze activities that are Value Added (VA), Non-Value Added (NVA), and Necessary Non-Value Added (NNVA). Based on the time calculation of the Current State Map (CSM), the total lead time is 554,016 minutes, with a VA of 303,773 minutes and an NVA of 250,243 minutes. Next, the improvement plan is made, which is described by using the Future State Map (FSM) based on the reduction of seven waste. The results show a reduction in the total lead time to 494,666 minutes, with VA being 303,774 minutes and NVA being 190,892 minutes. The most common waste that occurs is waiting and unnecessary motion. Furthermore, a proposed improvement is made based on VSM in warehouse layout from the results of ABC analysis calculation, with product placement based on classes A, B, and C. The product with the highest class A was the 390 PET X12 SPRITE CLR P5500 product. Keyword: Lean Warehousing, Warehouse, Value Stream Mapping (VSM), Waste, Seven Waste, ABC Analysis.
