Other activities of the villagers


The villagers, through the initiative of the headman and with the support of Jasa Tirta 1, other government agencies and a university, have also developed the fol- lowing activities:


Piloted biogas production for cooking, utilizing the animal waste from dairy cattle. This can help to overcome the waste problem from the husbandry as well as to reduce pollution flow into the stream and to improve water quality.
Harness small hydropower to provide 8 hours of night lighting to the village. This was carried out by harnessing a 2-metre drop of a 20-metre waterfall. The wa- terfall area is a recreational spot for the villagers. The decision to use only a 2-metre drop, channelled to the side, is to maintain this recreational area for the villagers, and especially the youth and children.
  1. Requests from the villagers


While some of the villagers who can afford it have built smaller, individual biogas facilities, the village has also submitted requests for the following activities, for which funds are still being identified. Constructing these biogas plants will reduce pollution from the dairy cattle activities and minimize cutting of forest trees for firewood needed for cooking. This will reduce pollution of the streams from both the solid waste and hillside erosion thus improving water quality. Concurrently, less cutting of trees and reforestation will ensure that the forest land is maintained to ensure reduced emission of greenhouse gases.




  1. Biogas plant and water treatment


To overcome the waste problem associated with animal husbandry, there is a need for construction or installation of at least one eco-efficient modular/in situ struc- ture to reduce pollution flow into the stream and to improve water quality. The proposed structure is biogas plant equipped with wastewater treatment. Biogas typically refers to a gas produced by the biological breakdown of organic matter in the absence of oxygen. Biogas originates from biogenic material and is a type of biofuel.


In Indonesia, the common type of biogas plant is “fixed dome”, which is an immobile fixed dome type. This type of biogas plant comes in various sizes (4, 6, 8, 10 and 12 m3) and categories (see table 1) to earn subsidies from the Indonesia Domestic Biogas Programme (IDBP/BIRU, biogas rumah).

a Processing capacity is the volume of biogas plant and the dome for the gas storage b Average storage time: 50 days
    1. Biogas plant 6 m3 with water treatment


Cattle waste treatment was achieved without regard to environmental sustainabil- ity, causing degradation of the water quality of the river. The selected construction of the biogas plant is type 2 with a processing capacity of 6 m3.

    1. Biogas plant 12 m3 with water treatment


Cattle waste treatment was achieved without regard to environmental sustainabil- ity, causing degradation of the water quality of the river. The selected construction of the biogas plant is type 5 with a processing capacity of 12 m3.
Location: Dusun Cukal Number: one site
