Abstract

UD OSHA Snack memproduksi berbagai jenis Snack, dengan keju goreng sebagai produk utama yang memiliki tingkat permintaan cukup tinggi. Penelitian ini menggunakan metode Fuzzy Sugeno untuk menganalisis akumulasi produksi per bulan berdasarkan data permintaan dan persediaan, serta metode regresi linier untuk mengevaluasi kerusakan produk akibat suhu penggorengan. Hasil analisis menunjukkan produksi optimal keju goreng mencapai 201 unit per bulan dengan rentang permintaan 70-250 dan persediaan 80-260. Suhu penggorengan berpengaruh sebesar 56,84% terhadap kerusakan produk, dengan persamaan regresi linier Y = 113,87 + 3,046X dan korelasi R = 0,754, yang menunjukkan hubungan kuat. Dengan analisis ini, pengelolaan permintaan, persediaan, dan suhu dapat dioptimalkan untuk meningkatkan efisiensi produksi dan kualitas produk.

Abstract

In the injection section of PT Natamas Plast, product sorting activities are performed using workstations with different types and dimensions of chairs and tables that have not been fully adjusted to operator anthropometric characteristics. This condition may result in non-ergonomic working postures and musculoskeletal discomfort. This study aimed to identify ergonomic problems in the product sorting workstation and provide a basis for ergonomic workstation redesign. The study was conducted through direct observation of working conditions and assessment of musculoskeletal complaints using NBM, while working posture was evaluated using REBA. The NBM results showed that operators experienced musculoskeletal complaints, particularly in the lower back, calves, and buttocks with the percentage complaints above 4%. The REBA assessment indicates that 5 out of the 9 operators are classified as having a high-risk level ranging score from 8 to 10. Anthropometric measurements were also performed to determine the workstation dimensions based on the 5th to 95th percentile, resulting in a proposed adjustable chair with a height of 39 to 49 cm and an adjustable worktable height from 136 to 159 cm. The proposed workstation design integrates musculoskeletal complaints, postural risk, and operator anthropometry to improve compatibility between the operator and workstation. The main contribution of this study is the development of a proposed ergonomic workstation based on REBA assessment and operator anthropometric data, which provides a technically justified intervention for mitigating identified ergonomic risks and serves as a basis for future implementation.
