Abstract

The fulfillment of energy for humans and animals is increasing day by day. This is evidenced by the fulfillment of electricity needs. This need is ab basic need, where humans and animals need electricity consumption 24 hours a day. So that renewable energy is needed with solar power generation for 12 hours of electricity. This research is focused on fulfilling electricity consumption in nile tilapia fish with 80 WP slar panels and 10 watt aerator power. The purpose of this study was to determine the level of dissolved oxygen in the water, the temperature in the water and the temperature in the surrounding environment. This research method uses a direct observation of dissolved oxygen with a predetermined data collection time using a dissolved oxygen measuring instrument that can be used in water. The result of this study indicate that the dissolved oxygen content produced is 14.61 mg/l with a thermal in water of 26.30C and thermal environment of around 280C.

Abstract

The purpose of this study was to lighten rice farmers and chili farmers so that there are no complaints of fatigue, joint pain because in perforating plastic it takes a long time to perforate. This tool method uses an electrical system which uses battery indicators and diameter sizes of 0.05 cm, 0.06 cm and 0.07 cm, so that it can make it easier for farmers according to the size to be used. This study was designed with an electrical system using 4 lithium batteries. The level of effectiveness of the resulting time in plastic holes with an area of 12 m2 is 10 minutes for 70 plastic holes.
