Abstract

Proses loading dan unloading adalah suatu proses yang dilakukan pada saat sebelum dan sesudah proses welding dilakukan. Pada proses ini terjadi aktivitas pengangkatan fixture welding dari meja assembly dibawa ke mesin dan dipasang pada mesin welding. Kemudian setelah proses welding selesai, fixture dilepas kembali dan dibawa ke meja assembly. Proses ini dilakukan oleh dua orang pekerja, karena fixture cukup berat, yaitu sekitar 52 Kg, dengan diameter 40 inchi, dan tebal 2.5 inchi, sedangkan jarak dari meja assembly ke mesin sekitar 300 cm. Berdasarkan penilaian Rapid Entire Body Assesment (REBA) didapatkan nilai skor akhir 9, dan digolongkan sebagai process dengan level resiko tinggi . Kemudian berdasarkan penilaian pada kuisioner Nordic Body Map (NBM) menunjukkan potensi timbulnya rasa sakit pada bagian tengkuk, bahu, lengan, punggung, pinggang dan betis, sehingga aktivitas ini kurang ergonomi bagi pekerja. Dari paparan kondisi diatas, kemudian diadakan survey dengan pendekatan quality function deployment (QFD), bahwasanya dibutuhkan alat bantu angkat untuk mengangkat fixture welding pada saat proses loading dan unloading. Untuk hal itu diusulkan perancangan sebuah alat bantu angkat berupa trolley atau lifter yang bisa menghilangkan kesulitan dan keluhan pekerja.

Abstract

Loading and unloading are the processes which are perform at before and afterwelding process. On this processes, there is a fixture-lifting activity from assembly table move to the Welding machine. The lifting activity as well is perform at after welding process; to uninstall the fixture from the machine then move it to assembly table. This process is performed by 2 persons, because the fixture is quiet heavy, 50 Kg with 40 Inches in diameter and 2.5 inches in the thickness. However, the distance from assembly table to the welding machine is 300 cm. Approximately By this condition, based on The Rapid Entire Body Assesment (REBA) Analysis is resulted Final Score 9 and categorized as a High Risk Level Process. As well based on the scoring of Nordic Body Map (NBM) shows result that there is a high potential pain on the nape, shoulders, arms, back, waist and calves, hence than this activity is consider as Not Ergonomic Process for the worker. Based on the condition as describe above, survey been conducted with Quality Function Deployment (QFD) approach, which concluded that the loading and unloading process is need a lifting tool or equipment to lift up and move the welding fixture. For this purposes to eliminate this difficulty, proposed to have a Lifting Equipment Design could be a trolley or a lifter.
