The transport industry stands out as a crucial domain in bolstering Indonesia's journey toward economic revitalization, swift progress, and equitable distribution. At present, Indonesia is in the process of establishing a high-speed railway sector that adheres to global benchmarks. Rail-based transit systems exert considerable influence on the mobility of both individuals and commodities. Trains possess the capacity to convey substantial volumes of commuters and freight in one journey, thereby playing a role in diminishing operational expenses for transportation fleets. Braking is an important aspect of driving because it affects safety, vehicle control, and vehicle efficiency. In order to develop braking research, high-speed train braking test equipment is needed to describe the actual conditions during braking. High-speed trains are a type of train capable of traveling at speeds above 200 km/h. The braking applied to these high-speed trains involves several combined forces, including regenerative braking and pneumatic braking. In regenerative braking, deceleration occurs due to the conversion of kinetic energy into electrical power. This mechanism is carried out when the train is at an operational speed of 220 km/h until it decelerates to 160 km/h. Next, pneumatic braking was applied at a speed of 160 km/h until the train slowed down and came to a stop. This study shows how the calculation process was carried out using a scale of 1:4 at a speed of 160 km/h.

The increasing number of motor vehicles in Indonesia produces repetitive mechanical loads on road surfaces that are rarely converted into useful energy. This study designs and evaluates a piezoelectric energy-harvesting speed bump intended to support low-power street lighting. The prototype integrates 25 piezoelectric discs (50 mm diameter) connected in series, an AC–DC bridge rectifier, a 2.7 V/500 F supercapacitor for short-term storage, and a DC–DC step-up converter to charge a 12 V battery. Field tests used a motorcycle at speeds of 5, 10, and 15 km/h with rider masses of 48, 70, and 79 kg; each condition was repeated ten times and averaged. Output voltage, current, and electrical energy per pass were measured after rectification. Results indicate that higher speed and mass increase electrical output, with a peak energy of 0.021 J at 15 km/h and 70 kg and an estimated conversion efficiency of about 0.20%. After repeated charging cycles, stored energy powered a 12 V/20 W LED lamp for several minutes. The proposed integration of series piezoelectric elements with supercapacitor buffering and step-up regulation demonstrates a feasible micro-energy harvester for traffic-dense areas and provides a basis for durability and scaling studies. Future work addresses packaging, fatigue, and multi-vehicle loading.
