Identification of Waste in The Production Process Using Lean Manufacturing Approach (Case Study: PT. Multiyasa Abadi Sentosa)

Abstract

PT. Multiyasa Abadi Sentosa is an export company specializing in handmade crafts using natural materials such as banana fiber, rattan, and seagrass. The production process of baskets faces challenges such as rejected products, which slow down processing time, leading to shipment delays and increased production waste. This research aims to identify production activities, analyze waste, and propose improvements. The methods employed include Value Stream Mapping, Waste Assessment Model, and VALSAT. Research findings indicate that Value-Added activities contribute only 67.1%, while Non-Value Added and Necessary but Non-Value Added activities are also significant. Process Cycle Efficiency is 67%. The largest sources of waste are defects in products and transportation. Implementing Quality Control for raw materials and optimizing transportation are proposed solutions to reduce waste.
