Abstract

This research aims to determine the performance measurement of Green Supply Chain Management at PD SP Leather and to make improvements to the underperforming aspects. The stages of this research consist of two phases: measurement and improvement recommendations. The measurement is conducted using the Green Supply Chain Operations Reference (SCOR) method, assessing 6 business processes, namely Plan, Source, Make, Deliver, Return, and Enable. The improvement recommendations are made using the Analytical Hierarchy Process (AHP) method. The Green SCOR measurement results indicate that out of a total of 17 designed performance indicators, 6 of them are considered subpar. The prioritization of improvement is determined using the AHP method, resulting in 6 alternative improvement options. Subsequently, the impact of these alternatives on the other 11 indicators is assessed using the House Of Quality (HOQ).

Abstract

CV. Aliyen Bag is a company engaged in the production of backpacks. The problem that often occurs in this bag production company is the presence of defective products. The defect tolerance set by the company is 2.5%. In an effort to minimize defects in backpack products, the purpose of this study is to determine the factors that cause product defects and the most dominant defects that can affect product quality. This research uses Statistical Quality Control (SQC) and Failure Mode and Effects Analysis (FMEA) methods. Based on the results of data processing, discussion and analysis, it is obtained that the most dominant factor causing defects is that the machine does not work optimally and the lighting environment is lacking, the most dominant defect is the RPN obtained is 160 which is caused by lack of lighting. This proposed improvement because of the high RPN results in lighting, it is proposed immediately by measuring the lux lighting with the results of 22500 lumens rounded up to 10 lamps with an average of 2300 lumens or 19 W. The implementation of this proposal is expected to improve product quality and minimize the occurrence of product defects, reduce costs due to defects, and increase customer satisfaction with the products produced.

Abstract

Pengelolaan risiko dalam proses bisnis rantai pasok merupakan aspek krusial dalam memastikan kelancaran operasional dan keberlanjutan industri. Penelitian ini bertujuan untuk mengidentifikasi risiko utama dalam rantai pasok, menganalisis dampaknya terhadap efisiensi operasional, serta mengembangkan strategi mitigasi berbasis pendekatan House of Risk (HOR). Metodologi yang digunakan mencakup identifikasi risiko menggunakan Failure Mode and Effect Analysis (FMEA), analisis probabilitas dampak, serta pemetaan strategi mitigasi yang tepat. Hasil penelitian menunjukkan bahwa risiko utama berasal dari ketidakpastian pasokan bahan baku dan ketidaksesuaian permintaan pasar, yang dapat menghambat produktivitas. Implementasi strategi mitigasi berbasis HOR mampu mengurangi tingkat risiko secara signifikan dan meningkatkan efisiensi rantai pasok. Studi ini memberikan kontribusi bagi industri dalam meningkatkan daya saing melalui pendekatan proaktif dalam manajemen risiko rantai pasok.
