Abstract

Penelitian ini berawal dari Kebutuhan energi listrik rumah-rumah di daerah terpencil seperti pedesaan didaerah Kalimantan Tengah sangat diperlukan disebabkan belum meratanya pasokan listrik ke semua pelosoknya, hal tersebut karena tidak dapat dijangkaunya jaringan listrik kesuatu wilayah tersebut oleh berada di daerah kawasan yang sulit untuk dijangkau pasokan listrik, padahal didaerah tersebut banyak sumber-sumber air mengalir yang dapat dimanfaatkan.

Penelitian ini bertujuan (1) Mengetahui pengaruh variasi kedalaman sudu terhadap kecepatan putar generator rancang bangun kincir air tipe undershot model 9 sudu tetap. (2) Mengetahui pengaruh variasi kedalaman sudu terhadap daya keluaran generator rancang bangun kincir air tipe undershot model 9 sudu tetap. (3) Mengetahui karakteristik generator dalam menghasilkan daya maksimum. (4) Mengetahui efisiensi kinerja kincir air dalam menghasilkan mengkonversikan daya kincir. (5) Mengetahui efisiensi kinerja Generator dalam menghasilkan energi listrik.

Penelitian ini menggunakan metode eksperimental. Kegiatan yang dilakukan dalam penelitian ini meliputi persiapan dan perancangan kincir air sudu Tetap.

Hasil penelitian menunjukan bahwa (1) Kedalaman sudu sangat berpengaruh terhadap perubahan kecepatan putar generator. Setiap kedalaman sudu memiliki karakter yang berbeda-beda terhadap Kecepatan putar generator. (2) Daya listrik terbesar dimiliki oleh kincir air dengan kedalaman sudu 30 cm dan daya listrik terkecil dimiliki oleh kincir air dengan kedalaman sudu 15 cm. (3) Karakteristik generator menyesuaikan dengan hambatan atau beban yang di berikan pada output generator, Daya maksimum generator yang dihasilkan pada saat dihubung singkat dengan kecepatan putar generator sebesar 151 rpm adalah 115 watt (4) Efesiensi terbesar kinerja kincir air dalam mengkonversikan daya air terjadi kedalaman sudu 0,15 sebesar 0,61% pada kecepatan air 1,44 m/s.

ABSTRACT

This research is started from the necessity of houses' electric energy at isolated area such as village of central borneo. It is needed so much, because electricity supply is not spread evenly yet to all of isolated area. This case happens, because electricity wire cannot reach that area. It caused that area was out of electricity range, although there many water sources which was useful.

This research was aimed to (1) know influence depth blade variation towards rotational speed of waterwheel generator construction of undershot type of 9 permanent blades model. (2) know influence depth blade variation towards output power of waterwheel generator construction of undershot type of 9 permanent blades model. (3) know generator's characteristic in producing maximum power. (4) know efficiency of waterwheel performance in converted waters power .(5) know efficiency of generator performance in producing electric energy.

This study would conduct experimental study. The activities conducted in this study were preparation and waterwheel construction of permanent blades.
The result of study showed that (1) Depth of blade was very influence toward change of generator rotational speed. Every depth of blades provided different characters toward generator rotational speed. (2) the biggest electric power was produced by waterwheel with depth blade about 30 cm, and the smallest was produced with depth blade about 15 cm. (3) generator's characteristic adapted of load or resistance which were burdened on generator output maximum power of generator was produced when short-connected to generator speed rotation about 151 rpm was 115 watt. (4) the biggest efficiency a Float Waterwheel Performance was converted water power the depth of the which was 0,15 cm about 97,26% at velocity of water 1,56 m/s. (5) the biggest efficiency a Float Generator Performance was converted water power the depth of the which was 0,15 cm about 0,61% at velocity of water 1,44 m/s
