Indonesia consist of 16.056 islands and the area is 1905 million. Due to the vast number of island and region, the value of electrification ratio of Indonesia is uneven, some region has a ratio below than 50%. Not only electrification ratio, electricity demand in Indonesia also increase around 5.5% every year. Some obstacles in improving electricity in Indonesia are related to energy infrastructure. Prioritize border and rural area by using renewable energy source is one of the governments attempt to solve the electrification problem. For the last 10 years, the used of renewable energy as an energy source has increased around 4.7% in average, in 2016 has increased 7.1 %, but the used of solar as an energy source only reached 1%. The home distribution pattern in border and rural area is spread around the area. Due to that distribution pattern, the right design of power plant should design well. This study will show that hybrid distributed system is more suitable and applicable for border area, in this case, is Sei Bening, the cost is lower than the centralized system and each module able to backup each other.

Hydride materials, used in hydrogen storage technologies, in powder form can be an explosion hazard and testing these materials using standard techniques is difficult. Research reported in this paper is an attempt to develop numerical methods to obtain explosion properties of such materials. In this work a one-dimensional transport-type model is presented to simulate the dust explosion process in a closed 20-L spherical vessel. Transport equations for energy, species and particle volume fraction are solved with the finite difference method, whilst velocity distribution and pressure are updated with numerical integration of the continuity equation. The model is first validated with experimental data and then applied to simulate the explosion process of an AB2- type alloy powder used for hydrogen storage.
