From 2014 to 2018, the number of traffic accidents grew 3.30% annually. By 2018, there were 109,215 case of traffic accidents. Out of those 109,215 cases, there were 173,358 people that became casualties. 75.3% of them were killed. In addition, from 2014 to 2018 the number bus in Indonesia grew by 1.42% annually. By 2018 there were 2,538,182 units buses roaming in Indonesia. One of the most common form of motor vehicle accident is frontal collision. In this research, the writer will simulate the frontal collision by conducting a sled test by using LSDyna PrePost and ANSYS Mechanical APDL. For the sled test, the writer will utilize a modified version of Hybrid III 50th Percentile Male Rigid made by Livermore Software Technology Corporation. The focus of the research is to find the correlation between the injury received by the victim and the distance between adjacent row of seats. There will be 3 distances to be used, these are: 650 mm, 825 mm, and 1000 mm. For each distance, the dummy will be subjected to different type of seatbelt usage, these are: no seatbelt, 2-point seatbelt, and 3-point seatbelt. For the analysis, the writer analysed the injuries from 5 different areas, these are: head, neck, chest, right femur, and left femur. From the results obtained, it can be concluded that the effect of distance variation has no clear trend towards any case with no seatbelt. For cases with 2 and 3-point seatbelt, there are clear trends with the seat row distance variation.
