Renewable Energy Promotion Support in Indonesia
１．Seriwe hamlet using renewable energy
Seriwe hamlet lies in remote area in East of Lombok Island. It has no access to electricity and the clean watersare purchased from the neighborhoods villages at higher price. About 85% of the population earn less than US$0.82/day. The main livelihood of the hamlet is to grow seaweeds and after harvesting they have to dry seaweeds,using direct sunshines. It has however a potential source of renewable energy namely solar and wind areavailable all year round. The proposed activities are first to conduct detail survey to the hamlet to obtain new dataon renewable energy sources and seaweeds production and later to provide the cooperative with , a powersupply system using a combination of solar PV and wind power generation for a small seaweeds processingfactory, a clean water supply facility, a hybrid solar dryer. In addition the project aims to increase the value addedseaweeds production, to find the market of the finished products, to provide the necessary education and trainingfor the operation/maintenance of these apparatuses and facilities. The activity also plans to transfer the factorymanagement methods and to assist in getting a financing instutiton to support the sound management.
With acomplishment of those activities, the project establishes the local people with stable and low cost electricity,heat and water, new job opportunties, increasing their living level and leads to welfare community.
The results from this project will expand to similar hamlets in Indonesian islands by creating open lecture in thegraduate 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 previous study on the hamlet hasbeen conducted to obtain the potential of natural resources and renewable energy(biomass, hydro power)available in the village, and to obtained the socio-condition of the people of the village.The main source of incomeof the Tangsi Jaya hamlet has been from paddy farming with average ownership of 0.12 Ha/household and from15.82 Ha of coffee plantation. In the past the harvested coffee berries have been sold to the middlemen underunprocessed condition.
The people in this hamlet have been living under poverty for a long time with an average income of around US$ 2/day. About 48% of the population has income of less than US$ 0.75/day. Fortunately, now in the village there exista micro-hydro power plant having a capacity of 18 kW supplying electricity for lighting during night time to around74 household (HH,298 people). This power generating facilities together with the Coffee Processing Center wasbuilt some 7 years ago by the government Energy Self Sufficient Village program but left unmonitored. Therewere no additional grant from the government for maintaining these facilities, and consequently the CoffeeProcessing Center 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 some renovationonthe water channel including embankment should be made. During the daytime the electricity produced from micro-hydro power was only used to supply electricity to the community during night time.The processing center wassmall in dimension and there is a need to make it bigger to accommodate new facilities. The hamlet has severalnatural resources yet to be developed, namely coffee plantation, rice field and vegetable farms. The purpose ofthe project is to supply electric power from refurbished micro-hydro and biomass (coffee skin) during the day timeto a newly build 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 for povertyalleviation. The projects lead to emission reduction for 6 months operation (with 0.5 kg CO2/kWh) the processingfacilities will mitigate emission equivalent to 3.5 Tons of CO2/year. Coffee skin will be used as fuel for the dryer.Emission coming from it is not included in the calculation because of of CO2 neutral. The project has anotherseveral advantages, namely preservation of natural resources by well keeping (improve and maintain) coffeeplantation and to increase yield in the form of driedcoffee beans. The renovation of micro-hydro power waterchannel and its embankment leads to the preservation of ecosystem services.
