The Risk Priority Number (RPN) At A Level Crossings Along The Railway Line In Indonesia
Keywords:Risk, Risk Assessment, Potential Causes, Severity, Occurrence, Detection, RPN
Indonesia has 7,464 km of railway lines along with the islands of Sumatra and Java. There are 5,239 level crossings along the railway line spread over 9 Operational Areas (Daop) and 4 Operations Divisions (Divre). According to data from the Directorate General of Indonesian Railways, throughout 2020, there have been 456 accidents at official and unofficial level crossings. Furthermore, according to statistical data, the number of accidents continues to increase every year. This study performs a risk assessment based on potential causes based on the frequency of occurrence, severity, and detection level. The method used is Failure Mode and Effect Analysis to conduct a risk assessment by identifying potential causes based on the probability of occurrence, assessing the level of impact caused, the frequency of accidents, and the ability to detect accidents on a scale of 1 to 5, which will then be calculated as Risk Priority. Number (RPN). Initial results were obtained. The results are that nine factors that cause accidents at level crossings have been identified, and 16 types of failures have been obtained from these factors. Level crossings that do not have doorstops are a potential cause with a risk priority number (RPN) of 80. The absence of guards contributes to the high severity of accidents. Based on observations, level crossings that do not have gates are dominated by unofficial level crossings. The second factor that must be an essential concern is the driver's behavior when passing at level crossings. The driver factor is very difficult to detect because it is necessary to disseminate information about maintaining safety at level crossings.
