Abstract

Advances in science and technology are increasingly sophisticated and complex. Smart devices, smartphones, tablets, and other complicated media mark the rapid development of communication technology. Smart devices are electronic devices, generally connected to other devices or networks via different wireless protocols. One example of a smart device that is widely used is a smartphone. People frequently use smartphones as a communication tool in the current global era. As a result, most people are dependent on these devices, which can expose them to harmful electromagnetic waves. Given the dangers smartphones can cause to people, it is recommended to limit the use of smartphones. Therefore, the purpose of implementing this community service is to educate the public, especially students and teachers at SDN 16 Bekut, on the dangers of smartphone radiation. This is done by educating people about the need to use smartphones responsibly and not excessively. Based on the questionnaire results and recapitulation of the results of this activity, it was found that the level of understanding and satisfaction index of the actifvity participants reached 86.45%.

Abstract

PLTMH merupakan pembangkit listrik skala kecil yang menggunakan tenaga air sebagai tenaga penggerak dengan memanfaatkan head dan jumlah debit air. Seperti di Desa Galar, Kecamatan Sompak, Kabupaten Landak yang akan memanfaatkan tenaga air dari riam di Bukit Raya. Tujuan penelitian untuk mengetahui debit lapangan, debit andalan, head, daya terbangkitkan, desain PLTMH meliputi komponen bangunan air, dimensi turbin pelton dan penentuan letak rumah pembangkit. Pada penelitian dilakukan pengukuran aliran air dan pengukuran head, data diolah dengan analisa debit andalan menggunakan metode mock dengan hasil perhitungan evapotranspirasi potensial menggunakan metode Penman-Monteith. Didapat hasil debit lapangan 0,04 /det, debit andalan 0,02 /det dengan head bruto 100,2 m potensi daya yang dapat terbangkitkan ialah 12,4 kW dapat digunakan untuk 28 rumah jika menggunkan listrik 450 watt. Perhitungan bangunan air meliputi volume bak penenang 10,32 , diameter pipa pesat 6 inci, komponen dari dimensi turbin yaitu (U1) = 21,7 m/det, (D) = 1730 mm, (C1) = 43,4 m/det,   (d) = 24 mm, (b) = 22 mm, (h) =   65 mm, (t)   = 24 mm, (a) = 29 mm, (Do) = 1808 mm, (Z) = 113 buah. Rumah pembangkit yang terletak pada elevasi +254 m dengan ukuran 6 x 8 m.Kata Kunci: PLTMH, Debit Andalan, Pembangkit dan Turbin Pelton.
