Abstract

Product quality is critical in today's competitive business environment, as it determines customer satisfaction, operational efficiency, and market competitiveness. Variability in the production process is often the main cause of product defects, which lowers customer satisfaction and increases production costs. The Six Sigma method with the DMAI (Define, Measure, Analyze, Improve) approach can reduce variability and improve process capability. This study focuses on implementing Six Sigma in the Indonesian furniture industry, which saw a 28.93% increase in export value in 2021 but still needs to improve with product quality consistency. One furniture manufacturer experienced a laminating defect rate of 3%, exceeding the company's standard of 1%. Through the DMAI phases, this research identifies the leading causes of defects and develops improvement recommendations. Analysis using control charts, DPMO, Pareto diagrams, FMEA, and RCA revealed that most defects are caused by human factors, such as operators not performing machine checks and cleanings and using wooden pallets that do not meet standards. Improvement recommendations include creating standard checklists, conducting regular training, and implementing monitoring systems for machine checks, pallet cleaning, and setting pallet standard specifications. Implementing Six Sigma is expected to improve process capability, reduce defects, and enhance the company's competitiveness in the global market.

Abstract

Intisari— Emisi karbon terbesar berasal dari residu yang ditinggalkan dari aktivitas manusia. Pada volume besar dan tak terkendali, emisi ini menjadi penyebab utama pemanasan global. Sumbangsih emisi gas buang juga bersumber dari aktivitas sehari-hari masyarakat. Di negara Indonesia, yang termasuk dalam kategori negara berkembang, aktivitas masyarakat lebih banyak terakumulasi di tingkat desa. Desa Penambangan merupakan desa yang terletak di kabupaten Sidoarjo provinsi Jawa timur yang memiliki luas wilayah kurang lebih 150 Ha dengan jumlah penduduk 5.816 jiwa. Pada penelitian ini dilakukan kajian dengan pendekatan system dynamics bagaimana penanganan sampah di desa tersebut. Model system dynamics yang dihasilkan bisa digunakan untuk bahan pertimbangan pemerintah desa Penambangan dalam menangani sampah. Berdasarkan simulasi model, seiring berjalannya waktu, total tingkat emisi karbon dari sampah desa meningkat rata-rata 10.8% tiap bulan. Dengan melakukan penanganan sampah organing yang lebih komprehensif, emisi karbon berkurang hingga 90.4% dibandingkan kondisi awal di level model. Abstract— The largest carbon emissions come from residues of human activities. In large and uncontrolled volumes, these cause global warming. As an accumulation, The emissions also come from the daily activities of the community. In developing countries such as Indonesia, community activities are mostly accumulated at the village level. “Penambangan” is one of villages located in Sidoarjo, East Java, which has an area of approximately 150 hectares with a population of 5,816 people. In this study, a system dynamics approach was carried out on how to handle waste in the village. The resulting model can be used by local government for consideration in handling them. Based on the model simulation, the total level of carbon emissions of the community increased by an average of 10.8% per month. By carrying out more comprehensive handling of waste, carbon emissions are reduced by 90.4% compared to the initial conditions at the model level.

Abstract

Waste is a significant challenge in the manufacturing industry, including small and medium enterprises (SMEs) engaged in paving block production. This study applies the Lean DMAIC (Define–Measure–Analyse–Improve–Control) methodology to identify, analyze, and reduce waste in the production process. A case study was conducted at a paving block factory in East Java, which has an annual production capacity of 119,400 m². Data were collected from production records, observations, and interviews conducted between September 2024 and August 2025. Analysis using a weighted Pareto diagram and Flow Process Mapping revealed that defect categories, although accounting for only 1.99% of total production, resulted in a significant accumulation of dead stock in the storage area. Through a Decision Matrix and a radar chart, a recycling strategy was selected as the improvement solution. This strategy was subsequently formalized into a Standard Operating Procedure (SOP) for managing rejected products, ensuring consistent implementation and adherence. Evaluation of the implementation over one month showed a 23.8% reduction in dead stock volume. These findings provide empirical evidence of the effectiveness of integrating Lean DMAIC with circular economy principles in the paving block industry, offering a practical framework that can be replicated in similar manufacturing sectors.

Abstract

This research focuses on integrating lean thinking into a sanitary product manufacturing company, specifically through the identification and elimination of waste. The implementation of the Lean DMAI framework (Define, Measure, Analyze, Improve) is utilized as a continuous improvement strategy to enhance efficiency and reduce waste. Various tools such as Pareto diagrams, root cause analysis, and Failure Mode and Effect Analysis (FMEA) are employed in the stages of defining, measuring, analyzing, and providing improvement recommendations. Results of the study revealed that the waste with the highest Risk Priority Number (RPN) is in the form of defects, particularly in the sub-category of body cracks. The recommended improvement actions include the installation of temperature sensors and misting equipment, along with the application of damp cloths in the lower leg area. These measures aim to slow down the body shrinkage process.
