Analysis of Ergonomic of Sulphur Miners by Rapid Upper Limb Assessment (RULA) (A Case Study of Sulphur Miners of Mount Ijen, Licin Sub-district, Banyuwangi)

Abstract

Mount Ijen is one of a volcanoes series in East Java. Mount Ijen is still active and located in three regencies, there are Situbondo regency, Bondowoso regency and Banyuwangi regency. The high sulfur content makes Mount Ijen became mining area which one the main problems of sulfur miners is related to the ergonomics level of miners due to excessive workload that could potentially affect the health level of the worker. The study is analytic observational. Design of this study using cross sectional. The ergonomic assessment of sulphur miner used Rapid Upper Limb Assessment (RULA). The analysis technic of this study is descriptive. The result of assessments is the total score of Sulphur Stone Taking Process is 7 with action level is 4, total score of Sulphur Stone Lifting Process is 7 with action level is 4 and total score of Sulphur Stone Transport Process is 6 with action level is 3. The conclusion of study is RULA score of Sulphur stone taking and lifting process is level 4, shown that the condition of work posture of Sulphur stone taking process is dangerous for miner then investigate and change the work posture or implementation (in the near future) is necessary. And then, RULA score of Sulphur stone transport process is level 3, shown that further investigate and change the work posture or implementation soon is necessary.
