Abstract

UD. Jambo Aye Putra adalah sebuah usaha yang bergerak di bidang bongkar muat dan pengolahan kayu dimana kegiatan ini masih banyak mengandalkan tenaga manusia. Aktifitas bongkar muat kayu dilakukan secara manual dengan postur kerja yang berpotensi menimbulkan risiko gangguan muskuloskeletal akibat posisi kerja yang berbahaya seperti membungkuk, mengangkat beban berat, memutar tubuh, serta gerakan kerja yang dilakukan secara berulang-ulang. Penelitian ini bertujuan untuk mengidentifikasi tingkat resiko ergonomi pada pekerja bongkar muat kayu menggunakan metode Quick Exposure Check (QEC). Penelitian dilakukan terhadap enam orang pekerja bongkar muat kayu di UD.Jambo Aye Putra dengan pengumpulan data dilakukan melalui wawancara dengan pekerja serta observasi langsung terhadap postur kerja. Data yang diperoleh selanjutnya dianalisis untuk menentukan skor paparan (Exposure Score) dan tingkat tindakan yang diperlukan terhadap risiko gangguan muskoloskeletal. Hasil penelitian menunjukkan bahwa postur kerja cenderung tidak ergonomis. Aktivitas kerja yang dilakukan pekerja meliputi posisi membungkuk, mengangkat beban berat, posisi tubuh yang memutar, serta gerakan gerakan berulang khususnya pada lengan dan pergelangan tangan yang berpotensi menyebabkan gangguan muskoloskeletal pada bagian, bahu, punggung, leher dan pergelangan tangan. Menurut hasil penilaian dengan menggunakan metode QEC diperoleh hasil sebanyak lima pekerja memiliki persentase skor paparan di atas 50% dengan kategori risiko tinggi sehingga memerlukan tindakan perbaikan dalam waktu dekat. Sementara satu pekerja lainnya memperoleh persentase skor 42,05% dengan skor paparan 74 yang mana nilai ini termasuk dalam level tindakan 2 yang memerlukan perbaikan pada waktu yang akan datang. Secara keseluruhan hasil penelitian ini menunjukkan bahwa kondisi kerja aktivitas bongkar muat kayu di UD. Jambo Aye Putra memerlukan perhatian dan tindakan perbaikan ergonomi untuk mengurangi risiko gangguan muskoloskeletal pada pekerja.

Abstract

Heat exposure on the production floor is one of the hazards workers face during palm oil processing. It comes mainly from several machines on the floor, raising heart rate, speeding up the onset of fatigue, and disrupting workers' physiological condition. This study set out to analyze the environmental temperature on the production floor and workers' cardiovascular load, and to determine how environmental temperature affects their physiology. The methods used were the heat stress index, cardiovascular load, and simple regression analysis. Results showed the highest heat stress index was recorded at the boiler station, at 143%. Eleven workers across the work stations fell into the "improvement needed" category for cardiovascular load. Temperature had a positive effect on workers' heart rate, with a coefficient of 0.010; each 1°C rise in temperature was estimated to increase heart rate by 2.18 beats per minute.Keywords: Heat Stress Index (HSI), Cardiovascular Load (%CVL), Worker Physiology

Abstract

Crumb rubber production at PT. XYZ experiences bottlenecks in both wet and dry processes, resulting in raw material accumulation and disrupted production flow. This study aims to determine the standard processing time at each workstation and optimize the production process using ProModel simulation. A quantitative approach was applied using direct observation, interviews, and secondary company data. The results show that the total average processing time required to produce crumb rubber is 14,807.83 minutes. Simulation results identified bottlenecks mainly at the raw material and drying stages. After optimization, the utility value in the drying process decreased from 19.11% to 6.37%, while the drying machine utility decreased from 9.15% to 3.05%. These results indicate that the proposed simulation model can reduce bottlenecks and improve production process efficiency.Keywords: bottleneck, crumb rubber, promodel, production optimization, simulation
