Penelitian ini dilakukan untuk merancang rak selang hirolik sebelumnya yang ada di Bengkel Multi Teknik. Karena rak selang hidrolik diketahui belum ergonomis, sehingga para operator yang melakukan aktivitas pekerjaan mengambil dan membawa selang secara manual menyebabkan gangguan MSDs bagi operator yang mengharuskan membawa selang dan membungkukan badan saat mengambil selang didalam rak. Penelitian ini bertujuan untuk mengetahui skor keluhan Nardic Body Maps (NBM), Working Posture Analysis System (OWAS) serta Rapid Entire Body Assessement (REBA) serta merancang rak selang dengan metode antropometri. Berdasarkan hasil kuesioner NBM medapatkan skor 71,5 tingkat risiko tinggi. Perhitungan skor OWAS pada aktivitas mengambil dan membawa mendapatkan skor 3 dikategori perbaikan dilakukan segera. Untuk perhitungan REBA pada aktivitas mengambil dan membawa selang memperoleh skor 10 dan 11 berada di (action level 3 dan 4) yang tergolong dalam Tingkat risiko sangat tinggi. Perhitungan antropometri menghasilkan ukuran dan dimensi merancang rak selang hidrolik dengan ukuran tinngi rak pertama 166,5 cm, tinggi rak kedua 137,16 cm, tinggi rak ketiga 118,01 cm, tinggi rak keempat 88,52 cm, dan Panjang rak selang 124 cm.

This research was conducted to design a new hydraulic hose rack to replace the existing one at the Multi Teknik Workshop. The current rack was identified as non-ergonomic because operators have to retrieve and carry hoses manually while bending over, which causes Musculoskeletal Disorders (MSDs). This study aimed to determine complaint scores via the Nordic Body Maps (NBM) questionnaire, the Ovako Working Posture Analysis System (OWAS), and the Rapid Entire Body Assessment (REBA) systems, and to design the new rack using anthropometric methods. The NBM questionnaire results showed a score of 71.5 (high risk). OWAS calculations for the activities of retrieving and carrying hoses yielded a score of 3 (indicating improvement should be made immediately). REBA calculations for the same activities produced scores of 10 and 11 (Action Levels 3 and 4), which are classified as very high risk. Based on the anthropometric calculations, the designed dimensions for the hydraulic hose rack are: first shelf height 166.5 cm, second shelf height 137.16 cm, third shelf height 118.01 cm, fourth shelf height 88.52 cm, and hose rack length 124 cm.
