PT Naturindo Fresh is a traditional medicine manufacturing company certified with CPOTB that produces herbal products using a make to order system. Based on the observation results, the production process of the powdered capsule product family still contained several types of waste, indicated by the accumulation of work in process (WIP), waiting activities, capsule defects, and discrepancies between purchase orders and production output, which led to decreased production line efficiency. This study aims to identify the types of waste, analyze the root causes of dominant waste, formulate improvement proposals, and calculate the Process Cycle Efficiency (PCE) under current conditions and projected conditions after improvement. The methods used in this study include Value Stream Mapping (VSM), Waste Assessment Model (WAM), Value Stream Analysis Tools (VALSAT), and Root Cause Analysis using the Five Whys approach. The results showed five types of waste, namely motion, inventory, waiting, overproduction, and defects, with the dominant wastes being motion, inventory, and waiting, which became the focus of the proposed improvements. These wastes were caused by non ergonomic workplace facility design, the absence of WIP control, and imbalances in workload and process flow between workstations. The proposed improvements include the provision of portable ramps, the implementation of a daily WIP recording system with a maximum limit of ±22 batches, and the implementation of line balancing. The PCE value increased from 9,92% to 14,52%, indicating an improvement in production line efficiency. 2026-05-12 Thesis NonPeerReviewed text id https://digilib.uin-suka.ac.id/id/eprint/76884/1/22106060063_BAB-I_IV-atau-V_DAFTAR-PUSTAKA.pdf text id https://digilib.uin-suka.ac.id/id/eprint/76884/2/22106060063_BAB-II_sampai_SEBELUM-BAB-TERAKHIR.pdf Alfinatul Aisyah, NIM.: 22106060063 (2026) ANALISIS PEMBOROSAN PADA PROSES PRODUKSI PRODUK HERBAL DENGAN PENDEKATAN LEAN MANUFACTURING UNTUK MENINGKATKAN EFISIENSI LINI PRODUKSI (STUDI KASUS: PT NATURINDO FRESH, KULON PROGO).
