Abstract

PT. MPX adalah perusahaan pengelola coklat yang memiliki permasalahan mengenai pengelolaan persediaan dengan distibutornya, sehingga menyebabkan tidak stabilnya permintaan dari kedua pembeli, serta tidak ada waktu pengiriman yang optimal untuk keduanya. Pada kondisi nyata pihak pembeli dan pemanufaktur menetapkan ukuran lot optimalnya masing-masing, sehingga penulis melakukan penelitian untuk mencari lot pengiriman dan biaya optimal untuk semua level. Penelitian ini menerapkan metode JELS (Joint Economic Lot Size) antara pemanufaktur tunggal dan multi pembeli dengan permintaan probabilistik. Hasil dari analisa ini membuktikan bahwa dengan menerapkan metode JELS (Joint Economic Lot Size) pada pemanufaktur tunggal dan multi pembeli menghasilkan total biaya yang lebih kecil dibandingkan tanpa menggunakan metode JELS (Joint Economic Lot Size) serta didapatkan waktu pemesanan yang optimal bagi kedua pembeli.

Abstract

PT. XYZ is a natural gas trading company that was founded in 2003 and started to expand its business to East Java starting in 2012 with a total length of 18 KM pipeline. This study aims to determine what risks exist in the natural gas pipeline network and determine the remaining service life (Remaining Life) of the pipeline that can be used. The method used is by using a Risk Based Inspection (RBI) semi-quantitative method approach to determine the most risky sections and with ASME B.31.8 and API 570 standards for determining the nominal thickness and requirement thickness of the pipe to determine the remaining service life (Remaining Life) of the pipe. distributor. From the results of the study, it is known that several risks exist in the pipeline segment, including life risk, financial risk, environmental risk, social risk, legal risk and business continuity. Based on these risks, it can be seen that the ML-02 Pipe Section is the most risky section. In accordance with calculations with ASME B31.8 and API 570 standards based on pipe thickness and corrosion rate, the Remaining Life for Section ML-02 is the shortest, which is 15.42 Years. Referring to the calculation results on the ML-02 pipe section, if the average reduction in pipe thickness is calculated each year, the results show that the ML-02 pipe section at Point A, namely the Box Valve Pipe at the Bambe Village Office (BV02/ML02) is the most common. reduction in pipe thickness is 0.13 millimeters / year and has a shorter Remaining Life, which is 10.97 Years.AbstrakPT.

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.
