Abstract

Solar energy is the potential energy to be developed in Indonesia because Indonesia is a country located on the equator with radiation throughout of the year. One form of solar energy utilization is a source of electrical energy by using a device called a solar panel. The solar panel is a device that can absorb and convert solar energy into electrical energy. Electrical energy from conversion by solar panels is used as an energy source in a variety of electric device including thermoelectric coolbox. Thermoelectric coolbox is a device that used to store a product or material that requires cold conditions. Oyster mushroom (Pleurotus ostreatus) is a product of horticulture that has a short shelf life. Oyster mushrooms can only survive in a fresh state for one day after the harvest, but the oyster mushrooms can last for 4 to 5 days by storage at temperatures below 10°C and humidity (RH) above 80%. The purpose of this research was to utilize solar energy as an electrical energy source on coolbox thermoelectric for oyster mushroom (Pleurotus ostreatus) storage. This research conducted at the Department of Agricultural Technology, Faculty of Agriculture, Sriwijaya University on October 2015 to February 2017. The research method of consisted three stages (design, operation, and testing of system). The system design stage includes of the calculation to determine the number of panels and batteries to be used and then perform the preparation of a series of tools includes solar panels, thermoelectric coolbox, lowering voltage charger and battery. Stage operation of the system was operating thermoelectric coolbox with 500g oyster mushroom (Pleurotus ostreatus) as cooling load. In the last stage of testing system that includes measuring current and voltage flowing in coolbox during the operation to determine the amount of power on a coolbox in the field, as well as measuring the temperature and humidity inside the coolbox. The results showed that electrical energy from the conversion of 100 Wp solar panels is stored in batteries can be used to operate the thermoelectric coolbox. Total average power provided by the solar panels WP 100 for 3 day at 1025.86 Watts and the average power absorbed by 879.79 Watt. Thermoelectric coolbox can provide temperature and humidity needed for storage of oyster mushroom (Pleurotus ostreatus) is the temperature below 10°C with a humidity of 89.9%. Coolbox power requirement on the field during the operation which is an average of 32.5 Watt.
