Abstract

PT. Bakrie Autoparts produced BT-1804 products for 12 months, and of the 9537 units produced, there were 3572 product defects with various types of defects. Therefore, Six Sigma with DMAIC is used to minimize defect problems. In stages, define used Critical to Quality (CTQ), where 16 types of potential defects were found in the BT-1804 product. At stage Measure, the Pareto diagram measures the highest frequency of defects and the improvements needed. At stageAnalyze used the Fishbone Diagram, where this method focuses on repairing 1 type of defect in BT-1804, which is the type of machining defect that is the dominant defect. At stageImprove, correcting the root of the problem with FMEA (Failure Mode and Effect Analysis), where it was found that inaccurate machine settings had the highest RPN value of 100. So, suggestions were given by providing knowledge in the form of training related to production mechanisms and providing supervision of operator performance during the machine setting process. Keywords: Quality Improvement, Six Sigma, DMAIC; Failure Mode and Effect Analysis

Abstract

PT. Yanmar Indonesia merupakan perusahaan swasta yang bergerak dibidang industri komponen alat-alat pertanian dan generator. Pengendalian mutu merupkan hal yang sangat penting agar pelanggan merasa kebutuhannya terpenuhi oleh produk yang digunakan. Oleh karena itu PT. Yanmar selalu berusahan meningkatkan kualitas mutu dari produk mereka untuk menjaga kepuasan pelanggan dan bertahan di pangsa pasar. Akan tetapi PT.Yanmar dihadapi beberapa masalah kecacatan produk khusunya pada produk Cylinder Block 4TNV 88C. Tujuan dari penelitian ini adalah untuk mengidentifikasi penyebab masalah serta memberikan rekomendasi perbaikan untuk menurunkan persentase cacat tersebut. Pengendalian mutu dilakukan dengan metode Six Sigma dengan DMAIC (Define, Measure, Analyze, Improve, Control). Didapatkan dalam kurun waktu 12 bulan terdapat 10880 unit yang cacat dari total 337082 total yang di produksi, dan yang produk dengan kecacatan tertinggi yaitu Cylinder Block 4TNV dengan 776 atau sebesar 30,32%. Penyebab terjadinya kecacatan ini disebabkan oleh kurangnya penngetahuan tentang setting mesin dengan skor RPN yang diperoleh yaitu RPN 504. Usulan rekomendasi untuk memenimalisir adanya defect yaitu memberikan pengetahuan berupa training atau seminar terkait dari mekanisme perihal proses produksi yang dilakukan, dan memberikan pengawasan terhadap kinerja operator pada saat melakukan proses setting terhadap mesin. Serta memberikan pengetahuan untuk mengurangi adanya ukuran atau proses yang tidak sesuai.

Abstract

Urban centers worldwide are grappling with complex waste management challenges, including efficient collection, transportation, processing, and an over-reliance on landfills. A promising approach to mitigate these issues lies in bolstering public participation in waste separation, which could significantly improve recycling efforts. To effectively encourage this practice, it is crucial to understand the underlying factors that motivate community engagement in waste segregation activities. This study utilizes the Theory of Planned Behavior and the Norm Activation Model to identify and analyze determinants influencing individuals' propensity to separate waste in the sampling area of Balikpapan City, Indonesia. Balikpapan, one of the cities in Indonesia, is currently facing several distinct challenges related to waste management. Through the empirical validation of eight hypotheses, it becomes apparent that the presence of market facilitators (H3) and the influence of past behavior (H5) play pivotal roles in shaping the intention to engage in waste separation. The findings suggest that providing accessible, well-maintained market facilities and initiatives designed to enrich the public's waste separation experience are essential strategies. Implementing these strategies could significantly improve waste separation practices within specific urban contexts such as Balikpapan, Indonesia, and other cities facing similar environmental management challenges.
