Abstract

Abstract— The purpose of making this final task is to apply the solar power system as a source of electrical energy to move the water pump automatically in fish ponds. This system works automatically with the Water Level Control tool sensor (WLC), so that if the water level drops or rises then the water pump will automatically work. On this automated system use the Smart Relay SR2B121BD and the ZelioSoft 2 application. Data retrieval carried out at 10.00 -14.00 WIB, obtained data pumps 1 and 2 for a height of 1 cm for 30 minutes and a height of 2 cm for 70 minutes. The amount of discharge the pump produces 1 and 2 ranges from 37 L/M to 45 L/M.  Pump 1 Test results obtained an average efficiency of 7.68%, with the highest efficiency of 11.03% and the lowest efficiency of 5.26%, while the average pump efficiency of 2, 7.05% with the highest efficiency of 10.66% and the lowest efficiency of 5.41%. The average efficiency of the solar panels is 11.20% with the highest efficiency of 14.60% and the lowest efficiency of 7.29%.

Abstract

Energi angin merupakan salah satu energi yang dapat diubah menjadi energi listrik menggunakan turbin angin. Berdasarkan sumbu putarnya turbin angin terdiri dari dua macam yaitu turbin angin sumbu horisontal dan turbin angin sumbu vertikal. Turbin angin dengan sumbu vertikal mempunyai beberapa jenis diantaranya turbin angin Darrieus, turbin angin Savonius, dan turbin angin H. Tujuan dari pembuatan dan pengujian ini adalah untuk mengetahui pengaruh kecepatan angin dan efisiensi sistem dari turbin angin Savonius blade dengan variasi sudut serang pada kecepatan angin tertentu. Berdasarkan hasil pengujian dapat diketahui nilai daya generator tertinggi kecepatan angin 6 m/s didapatkan sebesar 3,85 Watt pada sudut serang 20° dan beban 1 lampu DC, pada kecepatan angin 7 m/s didapatkan nilai daya generator tertinggi sebesar 5,58 Watt pada sudut serang 0° dan beban 3 lampu DC, sedangkan nilai daya generator tertinggi pada kecepatan angin 8 m/s didapatkan sebesar 8,52 Watt pada sudut serang 5° dan beban 4 lampu DC. Nilai daya generator berbanding lurus dengan putaran turbin. Semakin besar Putaran turbin maka daya generator yang dihasilkan juga semakin besar.

Abstract

Wind energy is a form of energy that can be converted into electrical energy using a wind turbine. Based on the axis of rotation, wind turbines are of two types, namely horizontal axis wind turbines and vertical axis wind turbines. Wind turbines with a vertical axis have several types including Darrieus wind turbines, Savonius wind turbines, and H wind turbines. The purpose of this manufacture and test is to determine the effect of wind speed and system efficiency from the Savonius 8 blade wind turbine with variations in the angle of attack on wind speed. certain. Based on the test results, it can be seen that the highest generator power value is at a wind speed of 6 m/s worth 3.85 Watt with an angle of attack of 20° and a load of 1 DC lamp, a wind speed of 7 m/s worth 5.58 Watt with an angle of attack  f 0° and a load 3 DC lamps, wind speed of 8 m/s worth 8,52 Watts with an angle of attack of 5° and a load of 4 DC lamps. While the highest system efficiency value is obtained at a wind speed of 6 m/s worth 4,62 % with an angle of attack of 20° and a load of 1 DC lamp, a wind speed of 7 m/s worth 4,218 % with an angle of attack of 0° and a load of 3 DC lamps, wind speed 8 m/s worth 4,31 % with an angle of 5° and a load of 4 DC lamps.
