Renewable Energy Promotion Support in Indonesia１．Seriwe hamlet using renewable energy
Seriwe hamlet lies in remote area in East of Lombok Island. It has no access to electricity and theclean waters are purchased from the neighborhoods villages at higher price. About 85% of thepopulation earn less than US$ 0.82/day. The main livelihood of the hamlet is to grow seaweeds andafter harvesting they have to dry seaweeds, using direct sunshines. It has however a potential sourceof renewable energy namely solar and wind are available all year round. The proposed activities arefirst to conduct detail survey to the hamlet to obtain new data on renewable energy sources andseaweeds production and later to provide the cooperative with , a power supply system using acombination of solar PV and wind power generation for a small seaweeds processing factory, aclean water supply facility, a hybrid solar dryer. In addition the project aims to increase the valueadded seaweeds production, to find the market of the finished products, to provide the necessaryeducation and training for the operation/maintenance of these apparatuses and facilities. The activityalso plans to transfer the factory management methods and to assist in getting a financing instutitonto support the sound management.
With acomplishment of those activities, the project establishes the local people with stable and lowcost electricity, heat and water, new job opportunties, increasing their living level and leads towelfare community.
The results from this project will expand to similar hamlets in Indonesian islands by creating openlecture in the graduate school, workshop (site tour, seminar and training) and home pages.
Seriwe Renewable Energy
２．Tangsi Jayahamlet using renewable energy
Tangsi Jaya hamlet located at Gunung Halu Village West Java, have been selected as the E3i(Energy, Economy and Environment)) self-sufficientvillage model based on the fact that previousstudy on the hamlet has been conducted to obtain the potential of natural resources and renewableenergy(biomass, hydro power) available in the village, and to obtained the socio-condition of thepeople of the village.The main source of income of the Tangsi Jaya hamlet has been from paddyfarming with average ownership of 0.12 Ha/household and from 15.82 Ha of coffee plantation. In thepast the harvested coffee berries have been sold to the middlemen under unprocessed condition.
The people in this hamlet have been living under poverty for a long time with an average income ofaround US$ 2/day. About 48% of the population has income of less than US$ 0.75/day. Fortunately,now in the village there exist a micro-hydro power plant having a capacity of 18 kW supplyingelectricity for lighting during night time to around 74 household (HH,298 people). This powergenerating facilities together with the Coffee Processing Center was built some 7 years ago by thegovernment Energy Self Sufficient Village program but left unmonitored. There were no additionalgrant from the government for maintaining these facilities, and consequently the Coffee ProcessingCenter almost deserted and the processing facilities were under corrosion.Recently the waterchannel was destroyed by landslides.In order to continue supplying electricity to the hamlet somerenovationon the water channel including embankment should be made. During the daytime theelectricity produced from micro-hydro power was only used to supply electricity to the communityduring night time.The processing center was small in dimension and there is a need to make itbigger to accommodate new facilities. The hamlet has several natural resources yet to be developed,namely coffee plantation, rice field and vegetable farms. The purpose of the project is to supplyelectric power from refurbished micro-hydro and biomass (coffee skin) during the day time to a newlybuild Coffee Processing Center where coffee berries are dried which have captive market in Bandung.And Processing Center creates new job opportunity for the villager to increase their welfare and forpoverty alleviation. The projects lead to emission reduction for 6 months operation (with 0.5 kg CO2/kWh) the processing facilities will mitigate emission equivalent to 3.5 Tons of CO2/year. Coffee skinwill be used as fuel for the dryer. Emission coming from it is not included in the calculation becauseof of CO2 neutral. The project has another several advantages, namely preservation of naturalresources by well keeping (improve and maintain) coffee plantation and to increase yield in the formof driedcoffee beans. The renovation of micro-hydro power water channel and its embankment leadsto the preservation of ecosystem services.
