Abstract

Penurunan biaya logistik menjadi aktivitas penting untuk bisa mengurangi biaya produk dan mencapai yang kompetitif. .Lean Logistics bisa menjawab tantangan ini dengan mengidentifikasi pemborosan yang terjadi di proses logistik, dan melakukan perbaikan dengan perubahan proses dan peralatan serta pengurangan waktu proses..Penelitian ini berfokus pada Inbound Logistics komponen impor dan lokal pada suatu perusahaan otomotif yang menghadapi tantangan untuk mengurangi biaya inbound logistics, Analisis penurunan biaya dilakukan dengan menerapkan Value Stream Mapping (VSM) atau Material Information Flow Chart (MIFC), Process Activity Mapping,dan empat hukum logistik menurut Sistem Produksi Toyota. Dari VSM atau MIFC didapatkan bahwa semua proses logistik dikomponen impor dan local, merupakan Necessary Non-Value Added (NNVA). Lean logistics sudah tercapai dalam komponen lokal sementara dalam beberapa proses komponen impor belum tercapai, terutama terkait dengan proses eksternal. Faktor penggerak biaya logistik yang terdidentifikasi untuk komponen impor adalah efisiensi dan jumlah dari modul dan kontainer, sedangkan untuk komponen lokal adalah penggunaan truk (truck utilization), truck loading efficiency dan jarak tempuh setiap rute, yang semuanya akan mempengaruhi jumlah trip yang dibutuhkan. Dari hasil analisis biaya didapatkan beberapa usulan perbaikan. Hasil dari perbaikan bisa menurunkan biaya logistik pada komponen impor sebesar 28% dari target. Penurunan didapat dari pengurangan jumlah kontainer dengan merubah shipment pattern dan menggunakan kontainer high cube. Untuk komponen lokal bisa didapatkan penurunan sebesar 25.4% dari target dengan mengurangi jumlah trip dan meningkatkan efisiensi muatan.

Reducing logistic costs is an important aspect in reducing the overall cost of product. Lean logistics offers a solution to this challenge by identifying waste within the logistic processes, and providing countermeasures through proceses re engineering and introduce new equipment to reduce processing time This research focuses on the inbound logistics of local and imported parts.in automotive company facing a challenge to reduce the cost of inbound logistics.. An analysis of cost reduction through Value Stream Mapping (VSM) or Material Information Flow Chart (MIFC), Process Activity Mapping, and Toyota Production System’s own four rules of logistics found that all logistic processes in both local and imported parts are Necessary Non-Value Added (NNVA). Lean logistics have been in place in the local parts but not in the imported parts, especially relating to external processes. The analysis also identifies driving factors of logistic costs for both imported and local parts. Factors identified for imported parts are the efficiency and number of modules and containers. For local parts, the factors are truck efficiency, truck utilization, truck loading efficiency, and distance covered in each route; all influencing the number of necessary trips. These results are used to make deriverecommendations for improvements. The improved processes result in a cost reduction of approximately 28% of the target for imported parts. This reduction could be achieved through changing shipment patterns and the use of high cube containers. For local parts, cost reduction is 25.4% of the target, which was derived from reducing the number of trips made and increasing loading efficiency.
