Abstract

Abstrak Perusahaan CV. Akbar Metatama, yang berfokus pada pengecoran logam, menghadapi tantangan efisiensi produksi karena beberapa tahap produksi yang kurang efisien. Pemborosan yang sering terjadi tanpa disadari telah menjadi bagian dari rutinitas yang umum. Penelitian ini bertujuan untuk mengidentifikasi faktor-faktor yang menyebabkan pemborosan dan mengembangkan rekomendasi perbaikan menggunakan konsep Lean Manufacturing untuk meningkatkan efisiensi produksi dan mengurangi pemborosan. Metode yang digunakan melibatkan value stream mapping untuk mengevaluasi kondisi awal perusahaan, pemetaan aktivitas proses, identifikasi pemborosan menggunakan fishbone diagram, serta memberikan usulan perbaikan dengan pendekatan 5W+1H. Hasil penelitian menunjukkan bahwa faktor utama yang menyebabkan pemborosan adalah ketidaktersediaan peralatan, kurangnya tempat penyimpanan material, dan lingkungan kerja yang tidak nyaman. Transportation (8,79%) dan motion (21,07%) adalah jenis pemborosan yang paling dominan. Rekomendasi perbaikan termasuk pembuatan lemari penyimpanan alat pada setiap lantai produksi untuk mengurangi pemborosan motion dari 573,6 detik menjadi 252 detik, serta merancang ulang tata letak lantai produksi untuk mengurangi pemborosan transportation dari 1660 detik menjadi 356,6 detik. Kata Kunci: Waste,Lead time,Lean manufacturing,Value stream mapping ABSTRACT CV Company, Akbar Metatama, specializes in metal casting but is currently facing challenges in production efficiency. The company has identified several stages in the production process that are not as efficient as they could be, resulting in unnecessary waste. In order to address this issue, a research project has been conducted to identify the factors causing waste and develop recommendations for improvement. The research project utilizes the Lean Manufacturing concept to enhance production efficiency and minimize waste. The methodology employed in this research project includes value stream mapping to assess the initial condition of the company, mapping process activities, identifying waste through fishbone diagrams, and providing suggestions for improvement using the 5W+1H approach. The findings of the research indicate that the main factors contributing to waste are the unavailability of equipment, inadequate material storage, and an uncomfortable work environment. Among the different types of waste, transportation (8.79%) and motion (21.07%) are the most significant. Based on the research results, several recommendations for improvement have been proposed. These include the implementation of tool storage cabinets on each production floor to reduce motion waste from 573.6 seconds to 252 seconds. Additionally, redesigning the production floor layout is suggested to decrease transportation waste from 1660 seconds to 356.6 seconds. By implementing these recommended improvements, Akbar Metatama can enhance its production efficiency, reduce waste, and ultimately improve its overall performance in the metal casting industry. Keywords: Waste, Lead time, Lean manufacturing, Value stream mapping
