The global clean water crisis is exacerbated by significant losses in water distribution networks (WDNs), resulting in inefficient use of both water and energy resources. Traditional methods of leak detection and pressure management often fail to address these inefficiencies, leading to substantial water wastage and high operational costs. This research aims to design a sustainable, smart water distribution system using advanced technologies such as Machine Learning (ML) for leak detection and automated pressure control. The system employs real-time monitoring through IoT sensors, which continuously gather data on water pressure, flow rates, and other critical parameters. This data is analyzed using various ML algorithms, including supervised and unsupervised learning models, to detect anomalies indicative of leaks. Additionally, the system integrates automated pressure control mechanisms that dynamically adjust pressure to prevent over-pressurization, reducing both water loss and energy consumption. By combining leak detection and pressure control, the proposed system offers a more efficient, sustainable solution to water resource management compared to traditional methods. The expected outcomes include a significant reduction in water loss, enhanced energy efficiency, and improved water service quality. However, the implementation of such a system in rural or small-town infrastructure faces challenges, including sensor maintenance, algorithm reliability, and regulatory issues. A cost-benefit analysis suggests that while the initial investment in smart technologies may be high, the long-term savings in water and energy costs outweigh these costs.

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.
