Abstract

Background: One of the important nickel extraction processes is mixing nickel ore into Dry Ore Storage (DOS) material as the main intake of Kiln Reduction. To ensure mixed material quality, DOS Sample House operators regularly takes sample and test the homogeneity of samples manually. Material handled by lifting some buckets moved to be mixed, then 1/8 of mixed sample tested and 7/8 disposed. This test activity takes 15 minutes each for 35 samples in one shift. The aim of this study was to evaluate posture, determine the prevalence of work-related musculoskeletal disorder and fatigue of DOS Sample House II workers. Method: A random sampling method according to mining work activity type was used to obtain the sample. Total of seven workers data was collected by using Nordic Body Map for symptoms and subjective workload using Rating of Perceived Exertion (RPE) questionnaire; after they finished all tasks of their shift. Four out of 25 tasks in one test were selected (reject sample removal tasks) and assessed using Rapid Entire Body Assessment (REBA). Results: The mean age of seven workers was 37,4 years, all men, and they worked for 4,2 years on average. In one sample test, material needed to be lift were average 28,81 kg which above the recommended weight. The highest prevalence of work-related musculoskeletal disorder symptoms were lower back, right forearm, buttock, right shoulder and hip. RPE scored range was 4 to 7 that their work makes them sweat a lot and REBA scored range 8 to 10, which the risk is high, need investigation and immediately implement changes. Conclusion: The overall finding indicated that the process of selected tasks, reject sample removal task, will contribute to musculoskeletal disorder either for a short or long time exposure. Future research regarding this section needed to prevent or reduce the occurrence of musculoskeletal disorder.

Abstract

PT. XYZ merupakan salah satu perusahaan industri baja berskala besar di Indonesia. Perusahaan ini merupakan perusahaan yang sebagian besar proses produksinya menggunakan mesin dan peralatan serta area yang memiliki potensi bahaya yang tinggi apabila tidak dilakukan pengendalian. Tujuan dari penelitian ini adalah untuk mengetahui apa saja jenis potensi hazard, tingkat risiko dari hazard yang ditemukan serta upaya pengendaliannya dengan menggunakan metode HIRA, yang terdiri dari identifikasi bahaya, penlaian risiko, dan pengendalian risiko. Penelitian ini merupakan penelitian observasional. Data primer didapatkan melalui hasil observasi dan wawancara yang kemudian disajikan dalam bentuk tabel lalu dianalisis secara deskriptif. Hasil penelitian menunjukan bahwa pada proses produksi billet area peleburan terdapat 10 temuan hazard dengan 23 risiko kecelakaan dan penyakit akibat kerja dari 3 aktivitas pekerjaan. Berdasarkan hasil penilaian, dari 23 risiko pada proses produksi billet area peleburan terdapat 6 jenis risiko pada level low, 12 jenis risiko pada level medium, dan 5 jenis risiko pada level high. Adapun kegiatan yang telah dilakukan perusahaan untuk mengurangi risiko terjadinya hazard, namun ada beberapa upaya pengendalian yang masih belum dilakukan oleh perusahaan yaitu penggantian jenis tungku, penggunaan material handling pada beberapa kegiatan, mengisolasi ruangan sumber kebisingan, serta pendisiplinan dalam prosedur kerja dan penggunaan APD.
