Abstract

PT OSIN is a company that runs a business in the automotive manufacturing sector. The company applies aflow shop production model whose production pattern is line to line in series using the First Come FirstServe production scheduling method. The problem with the FCFS method which is considered to have notreached the optimal enough in meeting uncertain product demands, causing delays in the productionschedule, which has an impact on the flow or distribution of goods and can lead to increased production inactivities. The proposed improvement method is made to optimize production scheduling, focusing onminimizing the makespan values in the scheduling system's order. This study uses a heuristic approach tothe Campbell, Dudek, Smith (CDS) algorithm in overcoming scheduling problems. The CDS method is aproduction scheduling heuristic method developed from the Johnson algorithm in obtaining severalsequences of 6 types of work processes at the work center which aims to analyze the total time for eachprocessing process (makespan). Comparing the two methods using the FCFS method by sorting thescheduling according to the order of the initial order time produces a total value of 2,408.75 minutes, whileusing the CDS algorithm which uses 5 iterations produces a minor matter of 881.3 minutes. Comparing theresults obtained by applying the scheduling system with the CDS method can be used as a proposedimprovement in overcoming the delay in delivery and the production scheduling process.

Abstract

Pengelolaan persediaan material consumable seperti Alat Pelindung Diri (APD) memiliki peran penting dalam mendukung kelancaran proses produksi, terutama dalam industri otomotif yang memiliki kebutuhan operasional tinggi. Penelitian ini bertujuan untuk merancang standar Level Stock material APD dengan pendekatan kuantitatif menggunakan metode minimum-maximum stock level. Pendekatan ini mengacu pada data penggunaan aktual, kedatangan barang, serta lead time pengiriman. Lima Item APD dipilih sebagai sampel utama untuk dianalisis, dan hasilnya dijadikan dasar dalam penyusunan standar Level Stock yang optimal. Perhitungan meliputi kebutuhan harian rata-rata, fluktuasi pemakaian dan kedatangan, buffer stock, serta safety stock. Hasil simulasi menunjukkan bahwa kelima Item berada dalam batas Level Stock yang ditentukan tanpa mengalami stockout atau overstock. Perancangan standar Level Stock baru berdasarkan data historis dan simulasi menghasilkan efisiensi biaya penyimpanan dengan penghematan maksimal sebesar Rp22.484.013. Dengan demikian, penerapan metode minimum-maximum stock level berbasis data historis terbukti efektif dalam meningkatkan akurasi pengendalian persediaan, mengurangi potensi pemborosan, serta meningkatkan efisiensi operasional di lingkungan industri manufaktur.

Abstract

Ciptaunggul Karya Abadi is a private company engaged in the Manufacturing of Metal Stamping Parts, Tools and Dies. In the face of fierce industry competition, the consistency of product quality is a determining factor for competitiveness. The high rate of product defects is a major concern for companies as it impacts cost, efficiency, and customer satisfaction. This study aims to analyze the effect of the implementation of Total Quality Management (TQM) on reducing the level of product defects. The method used was a case study with data collection through direct observation, interviews with stakeholders, and document analysis over a period of four months. The results show that the application of TQM elements such as customer focus, obsession with quality, scientific approach, long-term commitment, teamwork, continuous system improvement, education and training, controlled freedom, unity of purpose, and employee involvement and empowerment have a significant effect in reducing product defects. The implementation of TQM is also able to create a better quality culture in the production environment. Based on the results of the analysis, it can be concluded that PT. Ciptaunggul Karya Abadi has implemented all elements of Total Quality Management (TQM) as an effort to improve product quality and reduce the level of defects, but the implementation is not fully optimal. Therefore, it can also be concluded that Total Quality Management (TQM) is an effective strategic approach to improve product quality in a sustainable manner.
