Abstract

UMKM Pentol Bakso Bu Nurus, bergerak di bidang produksi bakso beku dengan berbagai varian. Ketidakstabilan pasokan bahan baku dan tingginya kompetisi pasar mendorong perlunya penerapan optimasi guna memaksimalkan pemanfaatan sumber daya yang terbatas demi mencapai keuntungan tertinggi. Penelitian ini mengimplementasikan dua algoritma dari metode titik interior yaitu algoritma Affine Scaling dan Karmarkar dengan mempertimbangkan data seperti jenis produk, biaya produksi, takaran bahan, dan profit per unit. Analisis sensitivitas kemudian dilakukan untuk mengidentifikasi sejauh mana jumlah daging dapat berubah tanpa mempengaruhi solusi optimal. Hasil optimasi menunjukkan kedua algoritma memberikan peningkatan keuntungan sebesar 20,9%. Sedangkan dari analisis sensitivitas, diperoleh interval stabilitas untuk penggunaan daging, yakni 206.550 gram < b₂ ≤ 250.000 gram, di mana solusi optimal tidak berubah selama pasokan daging berada dalam rentang itu.

Abstract

Small and medium enterprises in flour processing still rely heavily on manual drying processes, which pose high risks of musculoskeletal disorders and low productivity. This community service program aimed to implement an ergonomically designed spreading and leveling machine to improve working posture and production performance at Kusuka Ubiku SME in Bantul Regency. The program was conducted through problem identification, assessment of workers’ physical complaints using the Nordic Body Map, posture risk analysis using Rapid Entire Body Assessment, ergonomic machine design based on anthropometric data through the Need–Idea–Decision–Action approach, followed by on-site implementation and mentoring. The results show a significant reduction in posture risk from a high-risk category to a low-risk category and an increase in worker productivity by 53.6 percent. These findings demonstrate that the application of ergonomics-based appropriate technology effectively enhances occupational health and operational efficiency in food-processing SMEs.
