Kajian Potensi Energi Bayu sebagai Penggerak Pompa Pengairan Pertanian Daerah Sare Aceh Besar
Abstract: The amount of
agricultural lands has been converted into residential land and industrial land
since a lot of farmland in the mountains has been opened. Groundwater and river
has been used to irrigate the agricultural lands. Farmers in the mountainous
areas typically use his physical effort to get water from river to agricultural
land. This causes inefficiency of working for farmers thus the agricultural
productivity is not optimal. Owing the fact that agricultural land is far from
the electricity resources (PLN) therefore a small capital farmer must use pump
to irrigate their agricultural lands. Hence, farmers have to spend big amount
of money to buy fuel to drive the agricultural pump engine. Thus, it is
necessary to have a specific research on the availability of wind energy in
order to mobilize the agricultural pump engine in the mountainous area. In this
case, the authors have calculated and analyzed the potential of wind energy to
drive the pump in the village of Sare, Aceh Besar. From the analysis it has
been obtained that the average wind speed of 6,41 m/s with the diameter of
rotor turbine about 3 meter result in 1005,26 watt of wind turbine power. This
power can be used to power a 20 m head static pump, requiring 650 watt to
provide irrigation for 19 hectare of agricultural land 7 hrs/day. HOMER and
Epanet 2.2 software are used to conduct simulation for power system generation.
The result of HOMER simulation shows the lowest NPC value of US$ 10.028 with
the cost of energy (CoE) of USD 0.717 kWh. The systemcould produce electricity
power in a year of 3.452 kWh and the working length of the generating power system
is 15 years
