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.

Abstract

Keterbatasan akses informasi akibat infrastruktur yang belum memadai di beberapa daerah berpotensi menutup ruang keterlibatan masyarakat di dalam proses pembangunan. Hal ini menjadi penyebab sering terjadinya kegagalan dalam mencapai target pembangunan yang inklusif dan berkelanjutan. Kegiatan ini bertujuan untuk memastikan keterbatasan akses informasi masyarakat tersebut dapat diatasi melalui desiminasi teknologi papan informasi berbasis solar PV mulai dari sistem pemerintahan terbawah, yaitu desa. Aparatur Desa Surokonto Wetan dilibatkan sebagai mitra di dalam kegiatan ini. Pendekatan Participatory Rural Appraisal (PRA) digunakan di semua tahapan proses. Kegiatan ini menghasilkan seperangkat teknologi sistem informasi yang dapat diakses masyarakat secara luas untuk mendapatkan informasi sistem pemerintahan yang transparan.
