| Summary: | The energy crisis will come soon, the consumption behavior and
economic elevating will advance the energy depletion. The demand of power
electrical around 4.000 � 5.000 MW per year will difficult to fix, if we just rely
on fossil energy because of the increasing oil world price. The water energy is
one of the renewable energy can be used as solution. Based on annual reporting
of PT PLN (Persero) area NTB in 2012. Province of NTB has hydropower
potential 82,35 MW but until 2012 the ratio electrical is 50,95%. The building of
PLTA need high cost, so PLTMh is considered to solve soon the village
electrical demand.
Dusun Kaduk in Kabupaten Sumbawa Province of NTB is one of the
hilly and purilieus village area that has potential of coffee field, but doesn�t has
electrical sources. Pump as Turbine (PaT) is designed to change generator. The
advance of PaT are easy instalation and maintanance, mass production, avalaible
spare part and low investation so can utilize the maximum water potential. The
purpose of research to examine the suit PaT for local area, to analize capability
the centrifugal water pump type semi-open impeller SU-50 be used as PaT and
to get the characteristic of relation between water discharge to output power. The
experimental method is used to examine the layout PaT directly and note the
parameters used to analize of data.
The result of the research show the the centrifugal water pump type
semi-open impeller SU-50 used as PaT can produce 911,73 rpm, The maximum
power 61,09 W at head 4 m and the highest efficiency 19,05 %. The modified
impeller by using forward blade close impeller can increase 935 rpm, the
maximum power 62,35 W at head 4 m and the highest efficiency 20,42 %. The
highest spin 1194,83 rpm, the maximum power 85,80 W at head 4 m with
efficiency until 34,79 % is got by using backward blade close impeller. Result of
similarity analysis if discharge 85 l/s, head 21 m, diameter of pump 0,523 m and
highest spin 1600,094 rpm can produce power 311,211 kW. Based the research
the PaT can be used as alternative of electrical power sources in village. |
