Saltwater solution and seawater are naturally abundant resources containing dissolved salts that can generate electricity through electrolysis. This study explores their potential as alternative power sources for LED Lighting, focusing on their energy output and sustainability for rural and coastal areas. Researchers selected seawater from Ballesteros, Claveria, and Gonzaga in Cagayan, regions known for frequent electricity shortages, to examine their geographic diversity and suitability for alternative energy. Saltwater solutions using iodized, rock, and sea salts were also tested. Through experimental research, key variables such as salinity, energy output, and lumens were analyzed using recycled materials like carbon blocks and rods in the setup. Results showed that iodized salt achieved the highest initial brightness, peaking at 6.45V and 268 lumens. while seawater from Ballesteros produced the highest energy output, reaching 1655.5 mWh at 34 ppt salinity. Economic analysis revealed seawater to be more cost- effective, as it generated higher energy output (1655.5 mWh) with lower material costs compared to saltwater, which required the purchase of salts but delivered only 950 mWh. The study concluded that seawater is a more sustainable solution for long-term energy needs in coastal areas, lasting up to 35 hours per cycle, whereas saltwater solutions like iodized salt only lasted 22 hours per cycle. This indicates seawater's greater sustainability by providing approximately 60% longer usage per cycle. Future research should focus on optimizing and scaling this system for broader applications in energy-deprived regions.
