This study aims to analyze the implementation of the supervision policy for Inter-City Inter-Province (AKAP) buses carried out by the Class II Lampung Land Transportation Management Center (BPTD) in improving road transportation safety. The study employed a descriptive qualitative method with data collected through interviews, observations, and documentation. Data were analyzed using the interactive model of Miles, Huberman, and SaldaƱa, which includes data collection, condensation, presentation, and conclusion drawing. The findings indicate that the supervision policy has been implemented through ramp check activities, vehicle administrative inspections, operational permit monitoring, cross-sector coordination, and transportation safety education programs for drivers and transport operators. These supervisory efforts contribute to identifying vehicles that do not meet roadworthiness standards, thereby reducing the risk of traffic accidents. However, the implementation still faces several challenges, including limited human resources, inadequate supporting facilities, low compliance among some transport operators, and the high volume of vehicles requiring supervision. To address these challenges, the Class II Lampung BPTD has strengthened inter-agency coordination, enhanced law enforcement, optimized digital technology through the MitraDarat application, and conducted continuous transportation safety awareness programs. Therefore, effective transportation supervision requires the support of all stakeholders to further improve road transportation safety.
