UTILIZATION OF RENEWABLE ENERGY AT MARINE COMBAT TRAINING CENTER (PUSLATPURMAR-5) BALURAN EAST JAVA USING THE MILITARY MICROGRID CONCEPT TO SUPPORT THE STATE DEFENSE IN INDONESIA
Maintaining energy reliability in military installations is one form of implementing national defense. With energy reliability, military, non-military, and hybrid threats can be prevented. Puslatpurmar-5 is a military installation that requires electrical energy to support the activities of the marine corps of the Navy. The main problem faced by Puslatpurmar-5 Baluran related to energy is dependence on electricity from PLN and renewable energy has not been used optimally in operational activities. The aim of the research is to analyze the availability of renewable energy, the potential utilization of solar, wind and water energy as an alternative option, and the design of the military microgrid concept according to the capacity of solar, wind and waterpower plants that can be developed for Puslatpurmar-5 Baluran. The method used in this study is a quasi-qualitative method combined with field observation data and interviews. The results of the study show that renewable energy that can be utilized at Puslatpurmar-5 Baluran is solar and wind energy. Wind potential has an average speed of 3.9 m/s. Solar potential reaches 5.66 kWh/m2/d. The energy potential of water cannot be utilized because the speed of the river water is slow, the water discharge is small, and the elevation in the river flow is small. In conclusion, it was found that the use of renewable energy at Puslatpurmar-5 Baluran with the military microgrid concept was able to save PLN electricity costs by 30-43 percent. The design of utilizing wind and solar energy sources is also designed to maintain energy reliability and be safe from cyber-attacks.
