PT. IE is engaged in the business of making Lighting and Lampposts. Based on observations and interviews, there are still some wastes that arise in the flow of the production process, among which there are still many wastes of waiting time, transportation, movement and inventory. These wastes cause the product completion time to be longer and the resulting quality decreases. To eliminate or reduce waste, it is necessary to apply Lean Manufacturing. Lean Manufacturing is a systematic approach to eliminating waste and changing processes by identifying and reducing waste with continuous improvement and striving to create a production flow along the value stream by eliminating all forms of waste and increasing the added value of products to customers. From the Pareto diagram, it is found that transportation waste has the highest percentage of 26.21%, waiting time is 21.38%, motion waste is 19.31% and waste inventories are 15.17%. while the results of the Value Stream Mapping Current State Map mapping obtained a production lead time of 7,680 seconds and a total cycle time of 6,660 seconds and a PCE Current State Map value of 53.09%. Identify the root causes of waste using Fishbone diagrams, 5 Why Analysis, 5W+1H, Fault Tree Analysis and FMEA. After corrective actions have been taken, based on the Value Stream Mapping Future mapping there is a decrease in production lead time to 5,220 seconds and a decrease in total cycle time to 4,860 seconds and an increase in PCE Future State Map to 68.10% so that there is an increase of 15.01% which shows The company's production process has become more Lean.PT. IE bergerak dalam bisnis pembuatan Lighting dan Tiang Lampu. Berdasarkan observasi dan wawancara, masih terdapat beberapa pemborosan (waste) yang timbul di aliran proses produksi di antaranya masih banyak terjadi pemborosan-pemborosan waktu tunggu, transportasi, gerakan dan inventori. Pemborosan-pemborosan tersebut menyebabkan waktu penyelesaian produk menjadi lebih lama dan kualitas yang dihasilkan menurun. Untuk menghilangkan atau mengurangi pemborosan diperlukan adanya penerapan Lean Manufacturing.Lean Manufacturing merupakan pendekatan sistematik untuk mengeliminasi pemborosan dan mengubah proses dengan cara mengidentifikasi dan mengurangi pemborosan dengan perbaikan kontinu dan berupaya untuk menciptakan aliran produksi sepanjang value stream dengan menghilangkan segala bentuk pemborosan serta meningkatkan nilai tambah produk kepada pelanggan. Dari diagram Pareto ditemukan waste transportasi memiliki persentase paling tinggi sebesar 26,21%, waktu tunggu  21,38%, waste motion 19,31% dan waste inventories 15,17%. sedangkan hasil pemetaan Value Stream Mapping Current State Map diperoleh production lead time selama 7.680 detik dan total cycle time selama 6.660 detik serta nilai PCE Current State Map sebesar 53,09%. Identifikasi akar permasalahan pemborosan menggunakan diagram Fishbone, 5 Why Analysis, 5W+1H, Fault Tree Analysis dan FMEA.

PT PLB (pseudonym) is a company that produces household appliances and kitchen utensils. The country kettle is one type of product made by PT PLB. The productivity of the country kettle production line decreased by 56%. This was due to defective products. The largest percentage of defects in-country kettle products occurred in the spinning process of 40.18%. This study aimed to identify the causes of defects in-country kettle products and how to overcome them by designing improvement proposals. Lean manufacturing principles were used to evaluate the problems that occur. There were three types of lean manufacturing tools used in this study: Value Stream Mapping (VSM) and 5Ways. VSM was used to describe and identify value-added activities, non-value-added activities but necessary, and non-value-added activities so that the production process becomes lean. The root cause analysis was performed using the 5 Whys method. Unskilled workers and non-standard material types between suppliers are the highest contributors to defects in the spinning process. Based on this, this research was focused on improvements made in the spinning process. Proposals for improvements to the causes of the problems found are standardization of work procedures, standardization of supplier specifications, and arrangement of semi-finished goods and/or supplies. Based on the company's results, the proposed standardization of work procedures and arrangement of semi-finished goods and/or supplies may be implemented in the company. Meanwhile, the proposal for selecting suppliers is not feasible due to company limitations
