Abstract

This study aims to analyze the pivot type trailer operation with an ergonomic approach and the necessary interventions required to minimize work risks. Data collection was carried out using questionnaires and video recordings of the operators when the tractors as well as trailers were being operated at various conditions such as track, load, speed, straight motion or turn. Based on the Range of Motion (ROM) analysis, it was discovered that while operating this pivot type trailer, the upper body segments, such as neck, shoulders, elbows and back of the operator, comfortably controlled the tractor. Meanwhile, in the lower body segments, such as the thighs and knees, the operator generally felt discomfort. Furthermore, the analysis of the operator's subjectivity perception showed that discomfort was felt at several segments of the upper and lower body, such as the hands and knees. Therefore, several ergonomic interventions are required to increase the comfort of operating this pivot type trailer

Tujuan dari kajian ini adalah untuk menganalisis pengoperasian trailer tipe pivot dengan pendekatan ergonomi dan intervensi yang diperlukan untuk meminimalkan risiko kerja. Pengambilan dan pengumpulan data rekaman video operator dan kuisiner saat pengopearsaian traktor dan trailer dengan berbagai kondisi lintasan, muatan, kecepatan, gerakan lurus atau belokan. Hasil analisis natural Range of Motion (ROM) didapatkan bahwa secara umum pada pengoperasian trailer tipe pivot ini segmen tubuh bagian atas yaitu leher, bahu, siku, dan punggung operator dengan nyaman dapat mengendalikan traktor, sedangkan pada segmen bagian bawah tubuh yaitu paha dan lutut secara umum operator tidak nyaman karena lutut cenderung tertekuk sehingga perlu penyesuaian ketinggian tempat duduk. Analisis persepsi subjektifitas operator menunjukkan beberapa segmen tubuh atas dan bawah yang dirasakan kurang nyaman yaitu tangan dan lutut. Beberapa intervensi ergonomi diperlukan untuk meningkatkan kenyamanan pada pengoperasian trailer tipe pivot ini.
