Indonesia is a developing country located at the convergence of four tectonic plates, making it highly prone to natural disasters such as earthquakes, tsunamis, landslides, and volcanic eruptions. These frequent disasters highlight the critical need for reliable electricity during emergencies. However, disaster-affected areas often struggle to restore power due to accessibility issues. To address this, alternative energy sources are needed, and Solar Power Plants (PLTS) offer a practical solution. PLTS are easy to implement, depend only on sunlight, and provide clean energy with low carbon emissions. Under clear skies, solar radiation can reach 1,000 Watts per square meter, making it a powerful energy source. Additionally, PLTS systems are adaptable and can be deployed in various formats, including mobile units. This study focuses on designing a Mobile PLTS to support BASARNAS operations in disaster zones. Data collection was conducted using resources from BNPB, BMKG, BASARNAS, and NASA. The analysis includes the geographical characteristics of the site, solar radiation intensity, and the operational dimensions of the BASARNAS Mobile Truck. The study aims to determine the suitable system specifications and estimate the energy production capacity of the Mobile PLTS. The proposed design features 20 solar panels, each with a capacity of 300 Wp, producing an average of 27.70 kWh per day. It also includes 16 batteries for energy storage. The remaining space in the truck can be used for transporting logistics or essential tools, making it a multifunctional unit ideal for disaster response scenarios.

Indonesia, a developing country situated at the convergence of four tectonic plates, is highly vulnerable to natural disasters such as earthquakes, tsunamis, volcanic eruptions, and landslides. These geological conditions result in frequent disruptions, particularly affecting access to electricity in disaster-hit areas. Reestablishing power supply is often delayed due to logistical challenges. Therefore, alternative energy solutions are essential to provide immediate and reliable power during emergencies. One practical and sustainable option is the use of Solar Power Plants (PLTS), which rely solely on sunlight and produce clean energy with minimal carbon emissions. The earth’s surface can receive up to 1,000 Watts per square meter under ideal weather, making solar energy a viable solution. PLTS systems offer flexibility and can be adapted in mobile formats. This study proposes the design of a Mobile PLTS system suitable for use in disaster operations led by BASARNAS (National Search and Rescue Agency). Data were collected from BNPB, BMKG, BASARNAS, and NASA, focusing on geographical characteristics, solar radiation levels, and the dimensions of BASARNAS Mobile Trucks. The study aims to determine suitable system specifications, equipment needs, and potential energy output. The results show that the proposed Mobile PLTS system requires 20 solar panels (each 300 Wp), with an average energy production of 27.70 kWh. The system includes 16 batteries for energy storage. Additionally, the mobile unit design allows space for transporting logistics and essential tools, making it a multifunctional and strategic solution for disaster response in Indonesia.
