Abstract

This report presents the result of survey and mapping of bamboo and bamboo-waste in Bangli Regency done by LP2M/Faculty of Agriculture Warmadewa University in cooperation with Bali Clean Energy TaskForce for the purpose of calculating and estimating the potential of bamboo-waste as source of supply feedstock for 1 MW pilot project Community Based Biomass Fuel Cell (CBBFC) is planned located at Desa Bangkalet, in Bangli Regency. There were 178 households (HH) that having and planting bamboo at their land area, and 50 unit micro and smallscale household handy-crafts (MSSHH) that producing bamboo-waste by-product) surveyed. The respondents constitute of 4% of their total population, and nearly 98% of respondents agrees and supports the idea of the proposed pilot project. The total land area having by the said households is nearly 205.8 Hectare (≈ 2,058,000 m2), and out of this figure, there are around 105.7 Hectare (≈ 1,057,000 m2) specifically used for bamboo plantation, with typical bamboo’s density of 20 sticks/m2 and typical weight of 1.5 kg/m of bamboo-length. Based on site observation, and by using conservative-assumption that is default-number of specific bamboo-area is 30%, typical bamboo-waste produced by 1 stick of bamboo is 40% and efficiency of collecting bamboo-waste of 30%, then the total bamboo-waste that could be produced by the said household respondents is estimated to be of 31.3 ton/day. Moreover, there are 39 units (out of 50 units) of MSSHH have their own land area, this accounted of 14.8 Hectare (≈ 148,000 m2) of land, could produce 4.4 ton/day, and additional of 0.6 ton/day from their by-product-waste. Therefore, the sum up of all respondents could produce bamboo-waste at volume of 38.3 ton/day. The last figure is 2 times bigger than 15 ton/day of bamboo-waste required to produce 1 MW of electricity through Fuel Cell process.
