Abstract

This study aims to evaluate production waste at PT XYZ, a food manufacturing company in Bandung, Indonesia, which experiences inefficiencies caused by overproduction and product defects. A descriptive qualitative method with a case study approach was used, employing data from production reports, field observations, and interviews. The analysis was conducted using the 7 Waste framework, the 5S workplace organization method, and the PDCA (Plan-Do-Check-Act) cycle. The findings show that the main types of waste at PT XYZ are overproduction and defects, which are caused by inaccurate demand forecasting, ineffective layout, and inconsistent quality control. By implementing 5S and PDCA, the company successfully reduced waste, improved workspace organization, and increased process efficiency. This study provides practical insights for manufacturing companies seeking to implement lean strategies for continuous improvement.

Abstract

Supply Chain Management (SCM) plays a strategic role in improving competitiveness and consumer loyalty. This study aims to analyze the SCM factors that influence consumer loyalty to the BS UPI Student Cooperative (Kopma). The approach used is quantitative with a survey method, involving 40 respondents who are students of the University of Education Indonesia who have made purchases at Kopma in the past three months. Data was collected through questionnaires and analyzed using confirmatory factor analysis. The results of the study indicate that product variety, price, timeliness, facilities, availability, and product quality are important factors influencing consumer loyalty. From the analysis, it was found that product variety is the dominant factor most influencing consumer loyalty. The decline in Kopma's sales over the past two months underscores the need to enhance SCM strategies to maintain and improve consumer loyalty. These findings are expected to serve as a reference for Kopma managers in formulating more effective SCM strategies to address competitive challenges and meet consumer expectations optimally.

Abstract

PT CAM memproduksi AMDK galon Alexa 19 L dan mengalami hambatan produksi ketika ketersediaan bahan baku tidak mencukupi. Penelitian ini bertujuan menyusun perencanaan kebutuhan dan pengendalian persediaan untuk dua bahan baku utama, yaitu tutup galon dan seal galon, pada periode Januari 2023–Desember 2024. Metode yang digunakan adalah pendekatan kuantitatif dengan menyusun dasar kebutuhan melalui peramalan permintaan berbasis data penjualan historis 24 periode, kemudian menerapkan teknik lot sizing EOQ dan LFL sebagai alternatif kebijakan pemesanan. Model peramalan yang dipilih adalah DES α=0,1 karena memberikan nilai error terkecil pada dua metrik utama, yakni MAD dan MSE. Hasil menunjukkan total biaya persediaan metode perusahaan sebesar Rp 8.256.071, sementara EOQ menurunkan biaya menjadi Rp 4.407.902 (hemat 46,61%) dan LFL menjadi Rp 2.979.379 (hemat 63,91%). Dengan demikian, LFL menjadi opsi biaya terendah, sedangkan EOQ relevan bila perusahaan membutuhkan pola pemesanan yang lebih stabil.
