Abstract
This study aims to identify the root causes of chemical waste in the flavor R&D laboratory and provide improvement recommendations using Lean Manufacturing methods. The methods applied include Value Stream Mapping (VSM), Fishbone Diagram, and 5W 1H analysis to determine waste points and core problems. Based on observations, three main processes contribute to the waste: sampel preparation, product sampling, and inventory. Among them, the inventory process generates the most hazardous chemical waste due to overstock and expired materials. The main causes include the absence of a daily usage tracking system, lack of material classification based on usage frequency, and procurement policies that are not aligned with actual needs. The proposed improvements include implementing a digital inventory tracking system, revising the standard operating procedures (SOP) for inventory control, renegotiating the minimum order quantity with suppliers, and conducting regular evaluations of material usage. With these improvements, the laboratory is expected to significantly reduce chemical waste, increase operational efficiency, and minimize environmental impact. Keywords: Lean Manufacturing, Value Stream Mapping, Chemical Waste, Inventory, R&D Flavor, Fishbone Diagram, 5W 1H. Penelitian ini bertujuan untuk mengidentifikasi penyebab utama pemborosan bahan kimia di laboratorium R&D flavor serta memberikan rekomendasi perbaikan berbasis metode lena Manufacturing. Metode yang digunakan meliputi Value Stream Mapping (VSM), Fishbone Diagram, dan 5W1H analisis untuk mengetahui titik pemborosan dan akar masalah. Berdasarkan hasil observasi, ditemukan tiga proses utama penyumbang limbah, yaitu proses pembuatan sampel, sampling produk dan proses inventori. Dari ketiga proses tersebut, proses inventori menjadi penyumbang terbesar limbah bahan kimia berbahaya (B3) karena overstock bahan expired. Penyebab utamanya adalah tidak adanya sistem pencatatan pemakaian bahan, tidak adanya klasifikasi bahan sesuai dengan frekuensi penggunaan, serta kebijakan pembelian yang tidak berdasarkan kebutuhan. Aktual. Rekomendasi yang diajukan adalah penerapan sistem digital tracking bahan, penyusunan SOP inventarisasi, negosiasi ulang minimum order dengan supplier, serta evaluasi berkala terhadap penggunaan bahan. Dengan penerapan perbaikan ini, laboratorium diharapkan mampu mengurangi limbah kimia secara signifikan, serta meningkatkan efisiensi kerja, dan mengurangi dampak lingkungan. Kata kunci: Lean Manufacturing, Value Strema Mapping, Limbah kimia, Inventory R&D Flavor, Fishbone diagram, 5W1H analisis.
