Empowerment of solar renewable energy and low-cost interlocal telecommunication system for economic development of Panmutih Beach Fishermen Villages

This research aims to develop a solar power generation and telecommunication system based on LORA (Long Range) technology to support the economic development of fishing villages in Panmutih Beach, Kupang Regency, Nusa Tenggara Timur (NTT). The region faces challenges of limited electricity access and reliance on costly, non-renewable fossil fuels. Utilizing solar energy, this study proposes an energy cooperative model enabling fishermen to exchange fish catches for electricity, bypassing the need for internet connectivity. The research begins with an assessment of the region’s solar energy potential, revealing an average solar irradiation of 5.8 kWh/m2/day. Infrastructure design and deployment include installing 20 solar panels (each with a capacity of 300 Wp), a 50-kWh energy storage system, and a LORA-based energy distribution network capable of connecting 15 households. System testing shows a 70% reduction in energy costs. The cooperative system facilitated the collection of 0.5 tons of fish monthly, converted to 2,500 kWh of electricity. Socially, 80% of participants expressed increased satisfaction with their energy reliability, while environmentally, CO2 emissions were reduced by an estimated 5 tons annually. This approach provides a scalable solution for renewable energy access in remote areas, contributing to sustainable development and economic empowerment of fishing communities.
