Design and Development of Wind Energy The Simple HAWT Multiblade Type for Agricultural Irrigation Rainfed and Fishpond in Coastal Village of Situbondo District, Indonesia.

Abstract

Issues that are getting a lot of attention of Indonesia at this time and the future of which is the problem of
food security and energy conservation. Many rainfed agriculture land in coastal area is one of coastal village of
Situbondo which do not have technical irrigation so management is not optimal, during the dry season many farmers
make wells and raise the water with motor fuel pump, since the increase of fuel many farmers began to complain as
operational and maintenance costs are more expensive so that many rainfed fields are not managed during the dry
season. Though this area has a lot of wind energy potential during the dry season with an average wind speed of 2.5 - 4
m / s and blowing all day from 08.00 am to 16.00 pm.
The purpose of this research is to create and develop Multiblade HAWT Simple, Affordable Windmills and easily made
from local materials to raise irrigation water in rainfed agriculture during dry season especially in coastal area of
Situbondo. This windmill prototype can be used to raise seawater to fish ponds, thus supporting the food security and
energy conservation programs as they depend not only on the increasingly scarce and costly fossil fuels.
The design approach to design the windmill is done through several stages, among others; Literature review and field,
basic data collection and analysis, Design and testing. design method using the methods compiled by Gerhardt Pahl and
Wolfgang Beitz presented in Engineering Design book. The tests include structural and functional testing at the
Laboratory. After doing the field test; adaptation, functional, and verification tests. Then for the improvement made the
modifications and re-testing.
