Abstract

Besarnya volume pembangunan perumahan tiap tahunnya mengakibatkan tingginya permintaan buis beton sebagai produk siap pakai untuk membuat septic tank dan sumur resapan. Pembuatan buis beton dan tutup buis beton masih dilakukan secara manual, sehingga dapat mengakibatkan keluhan muskuloskeletal. Permintaan yang tinggi meningkatkan risiko muskuloskeletal bagi pekerja. Sakit pada sistem skeletal pekerja dapat menyebabkan turunnya produktivitas. Selain itu terdapat dampak jangka panjang, seperti perubahan struktur tulang pekerja yang menyebabkan postur tidak normal. Analisis dilakukan pada proses pembuatan tutup buis beton yang diduga memiliki tingkat risiko lebih tinggi untuk dapat mengurangi risiko muskuloskeletal pada pekerja. Simulasi model 3D digunakan untuk memudahkan analisis aktivitas gerak dinamis yang mendekati model aslinya. Perhitungan beban L5/S1, energy expenditure, dan analisis Rapid Body Assassement dilakukan untuk mengukur beban dan level risiko dari aktivitas. Hasil analisis menunjukkan postur pekerja yang perlu diperbaiki yaitu postur saat pekerja mengaduk adonan, mencetak tutup, dan memoles tutup buis beton. Perancangan alat bantu baru, yaitu desain pacul yang dibuat lebih panjang, desain alat tabur untuk proses memoles tutup, dan desain cetok seperti alas kaki, memberikan kondisi postur yang lebih baik untuk pekerja. Hasil uji kondisi perbaikan menunjukkan adanya penurunan jumlah konsumsi energi dan level risiko muskuloskeletal dengan penggunaan alat bantu. Terdapat penurunan konsumsi energi sebesar 63,25% hingga 70,15% pada aktivitas pembuatan adonan, 84,397% pada aktivitas meratakan adonan, dan 92,031% pada aktivitas menaburi bagian atas tutup. ================================================================================================== The large volume of housing development each year results in a high demand for concrete buis as a ready-to-use product for making septic tanks and infiltration wells. Making concrete buis and concrete buis cap is done manually, so it can cause musculoskeletal disorders. High demand increases the musculoskeletal risk for workers. Pain in the worker's skeletal system can lead to decreased productivity. In addition, there are long-term impacts, such as changes in the worker's bone structure that cause abnormal postures. The analysis was carried out on the process of making concrete buis caps which are thought to have a higher risk level in order to reduce the musculoskeletal risk for workers. 3D model simulation is needed to facilitate the analysis of dynamic motion activities that are close to the original model. Calculation of L5/S1 load, energy expenditure, and rapid body assessment analysis are carried out to measure the load and risk level of the activity. The results of the analysis show that the posture of workers that needs to be improved are the posture when workers mix the dough, print the lid, and polish the concrete buis lid. The design of the new tools, namely the design of the hoe which is made longer, the design of the sowing tool for the process of polishing the lid, and the design of the peck such as footwear, provide better posture conditions for workers. The results of the improvement condition test showed a decrease in the amount of energy consumption and the level of musculoskeletal risk with the use of assistive devices. There is a decrease in energy consumption by 63.25% to 70.15% in dough making activities, 84.397% in dough leveling activities, and 92.031% in sprinkling the top of the lid activities.
