Perancangan Fasilitas Kerja Polishing untuk Mengurangi Gangguan Muskuloskeletal di CV X

Abstract

Abstract. CV X is engaged in Mold and Die Casting in Bandung Regency. Operators in conducting research complained of pain in several parts of the body, one of the reasons being polishing activities which were carried out manually and repeatedly from rough to extra smooth surfaces, the work facilities provided caused the operator's way of working to become not ergonomic. The purpose of this research is to design ergonomic polishing work facilities so as to minimize the level of complaints and eliminate repetitive activities. The research method was carried out using the Nordic Body Map (NBM) questionnaire to determine the level of complaints and the Assessment Repetitive Task (ART) Tools method for measuring work risk. The results of the Nordic Body Map (NBM) questionnaire on the neck and wrist body segments workers experience very disturbing pain, the upper back body segment with disturbing pain, the elbow body segment experiences quite disturbing pain and on the shoulder and back body segments down experiencing a bit of nagging pain. The results of the work risk analysis on the chamfering and polishing process of the contents of the mold produce low to high exposure values. The highest exposure score results in the process of polishing the contents of the mold, this score indicates that the work is at risk and needs to be repaired immediately. The proposed design of work facilities is in the form of work tables and chairs as well as assistive devices in the form of sanding machines and sanding hoses to reduce repetitive manual activities. The results of the risk assessment for all work elements of the polishing process in the proposed work facility are in the low category. Keywords: Work Risks, Assessment Of Repetitive Tasks (ART) Tools, Nordic Body Map (NBM), Anthropometry, complaints of pain, level of risk and results of the design. Abstrak. CV X bergerak dalam bidang Mold and Die Casting di Kabupaten Bandung. Operator dalam melakukan penelitian mengeluhkan rasa sakit pada beberapa bagian tubuh, salah satu penyebabnya karena kegiatan polishing yang dilakukan secara manual dan berulang dari permukaan kasar hingga ekstra halus, fasilitas kerja yang disediakan menyebabkan cara kerja operator menjadi tidak ergonomis. Tujuan dari penelitian ini adalah merancang fasilitas kerja polishing ergonomis sehingga meminimalisasi tingkat keluhan dan menghilangkan kegiatan berulang yang. Metode penelitian dilakukan menggunakan kuesioner Nordic Body Map (NBM) untuk mengetahui tingkat keluhan dan metode Assessment Repetitive Task (ART) Tools untuk pengukuran risiko kerja. Hasil kuesioner Nordic Body Map (NBM) pada segmen tubuh leher dan pergelangan tangan pekerja mengalami rasa sakit sangat menganggu, pada segmen tubuh punggung atas dengan rasa sakit yang menganggu, pada segmen tubuh siku mengalami rasa sakit yang cukup menganggu dan pada segmen tubuh bahu dan punggung bawah mengalami rasa sakit yang sedikit menganggu. Hasil analisis risiko kerja pada proses chamfer dan polishing isi cetakan menghasilkan nilai eksposur rendah hingga tinggi. Hasil skor eksposur tertinggi pada proses polishing isi cetakan, skor tersebut mengindikasikan bahwa pekerjaan tersebut berisiko dan perlu dilakukannya perbaikan segera. Perancangan fasilitas kerja yang diusulkan berupa meja kerja dan kursi serta alat bantu berupa mesin ampelas dan selang ampelas untuk mengurangi kegiatan manual yang dilakukan secara berulang. Hasil penilaian risiko untuk seluruh elemen kerja proses polishing pada usulan fasilitas kerja berada pada kategori rendah.
