Design Build an Off Grid Based Solar Power Plant System Using The Bidirectional Buck And Boost Topology In The Conservation Of Sea Pearl Turtles

Turtles are one of the fauna that is threatened with extinction. The cause of its extinction is inadequate management of conservation techniques. The Lantera Trenggalek Community sees the problem of the high operational costs of turtle conservation faced by the people of Masaran Village, Trenggalek, East Java. The operational costs of turtle conservation are high, including the costs of turtle feed, turtle maintenance and the electricity costs for turtle egg incubators reaching 1800 watts, so they require high PLN electricity. Therefore, this research aims to innovate to overcome partner problems by utilizing off grid PLTS using Bidirectional Buck and Boost Converter. The aim of using PLTS in Masaran village is to increase the availability of electricity sources at relatively low prices. However, in the PLTS implementation system, the electrical energy produced is unstable. So the PLTS system is equipped with batteries to store energy. The energy storage process requires a converter which functions to stabilize the output voltage of the PLTS. This research used Bidirectional Buck and Boost Converters because these converters are able to work in two directions so they can optimize the output voltage from PLTS. The results of testing the PLTS system with Bidirectional Buck and Boost Converter show that when in buck mode, the converter output voltage can reach 14.4V which is used for battery charging. The output of this research is that the Off Grid PLTS system can produce maximum electrical energy so that it can overcome partner problems in increasing the turtle population.
