Abstract

Penelitian ini bertujuan untuk melakukan analisis ergonomi terhadap desain interior Low Deck Medium Electric Vehicle Bus yang sedang dikembangkan oleh Science Techno Park (STP) Otomotif ITS. Aspek kenyamanan dan keselamatan penumpang, khususnya pada desain kursi dan pegangan tangan (handgrip), dievaluasi secara mendalam guna meminimalkan risiko gangguan muskuloskeletal pada pengguna. Evaluasi postur tubuh penumpang dilakukan dengan metode Rapid Upper Limb Assessment (RULA) melalui tahapan simulasi digital menggunakan perangkat lunak CATIA V5. Pemodelan postur disesuaikan menggunakan data antropometri penduduk Indonesia persentil ke-50 agar hasil simulasi relevan dan sesuai dengan target pengguna aktual.Hasil simulasi awal pada kondisi desain eksisting menunjukkan bahwa postur penumpang berdiri memiliki skor akhir RULA 6, sedangkan penumpang duduk di area tengah dan belakang masing-masing mendapatkan skor 4 dan 3. Nilai tersebut mengindikasikan adanya potensi risiko ergonomis sedang hingga tinggi, yang diakibatkan oleh beberapa faktor struktural seperti posisi kaki penumpang duduk yang tidak menapak sempurna di lantai (menggantung) dan penempatan handgrip bagi penumpang berdiri yang terlalu tinggi. Berdasarkan temuan tersebut, dilakukan proses redesain yang meliputi pengurangan tinggi dan penyesuaian sudut sandaran kursi, serta penurunan ketinggian handgrip menjadi 1.730 mm dari lantai. Setelah dilakukan simulasi ulang pada desain hasil revisi, skor akhir RULA berhasil ditekan menjadi 2 untuk postur duduk dan 3 untuk postur berdiri. Penurunan skor ini secara signifikan menunjukkan bahwa usulan perbaikan desain berhasil meminimalkan risiko cedera serta mencapai standar kelayakan ergonomis yang baik bagi penumpang bus.

This study aims to conduct an ergonomic analysis of the interior design of the Low Deck Medium Electric Vehicle Bus currently being developed by the Science Techno Park (STP) Otomotif ITS. Passenger comfort and safety aspects, particularly the design of the seats and handgrips, are evaluated in depth to minimize the risk of musculoskeletal disorders for users. The evaluation of passenger body posture is conducted using the Rapid Upper Limb Assessment (RULA) method through digital simulation stages using CATIA V5 software. Posture modeling is adjusted using the 50th percentile of Indonesian anthropometric data so that the simulation results are relevant and align with the actual target users. The initial simulation results on the existing design condition show that the standing passenger posture has a final RULA score of 6, while the seated passengers in the middle and rear areas obtained scores of 4 and 3, respectively. These values indicate a moderate to high potential ergonomic risk, caused by several structural factors such as the seated passengers' feet not resting perfectly on the floor (dangling) and the handgrip placement for standing passengers being too high. Based on these findings, a redesign process was carried out which included reducing the height and adjusting the angle of the seat backrests, as well as lowering the handgrip height to 1,730 mm from the floor. After re-simulating the revised design, the final RULA scores were successfully reduced to 2 for the seated posture and 3 for the standing posture. This significant reduction in scores indicates that the proposed design improvements successfully minimize the risk of injury and achieve good ergonomic feasibility standards for bus passengers.
