BACKGROUND
Energy important for development
Indonesia, a developing nation
Low energy percapita, low electricity ratio
Need to shift into more renewable and clean sources
High Subsidy on energy
Detrimental impact on environment
Unbalance supply and demand on energy
BACKGROUND SOUTHEAST SULAWESI
COURTESY ADITYA UHO
Sea (74% or 110.000 km²). Land (26% or 38.140 km²)
Population 2.2 million [Ind. 250 million] GDP 1600 USD [Ind. 3000 USD] Poverty 12 %

HDI 71 [ Ind. 73 ] Economic Dev. 11 % [Ind. 6 %]
BACKGROUND BIOMASS POTENTIAL The total employment from agricultural sector around 45 percent
Agricultural sector generating more than 30 percent of its GDP
POTENTIAL
Land availability, rivers & fertilizer soil characteristic
Climatic condition [annual rain]
BACKGROUND PADDY & OTHER FOOD CROPS PRODUCTION
BACKGROUND THE DISTRIBUTION OF PADDY PRODUCTION DOMINATE The concentration of paddy production in three districts ; Konawe, Konawe Selatan and Kolaka

Data Annual Paddy Production [Angricultural Dept.]
Propoesed a model of power plant based on rice husk
- Annual Energy - Power capacity - Number of households
Var. Feedstock cost and Discount rate & Assumption of Project Life (25 yr) & Annual Degredation
RESULTS (POTENTIAL) 50 GWH, based on the porposed model of power plant [10 percent of the total annual current electricity use]
Power Capacity 5.8 MW [2.5 % current power intalled ]
The number of households potentially obtaining around 13 thousand, approximately 2.5 percent of the total households
DOMINATE
RESULTS (ECONOMIC) RH at the feedstock cost of 100 USD/ton < the energy costs based on diesel and gas.
RH at the lower feedstock cost of 25 USD/ton), < the energy cost based on gassteam and geothermal, and the electricity price under the government subsidy.
LCOE
OTHER
SUBSIDY
CONCLUSION
The annual potential huks energy is around 50 GWH, a 5.8 MW in capacity, potential delivering the service is more than 13 thousand,
At the feedstock cost of 100 USD/ton, it is possible to gain lower cost of the husk energy than that of the conventional electricity based on diesel and gas. As the cost is reduced to 25 USD/ton, it is possible to gain more attractive energy cost than those of the gas-steam and geothermal, as well as the electricity price under the government subsidy
