2. Study area and research methodology
2.1. Overview of study area
Semarang is the capital city of the Central Java Province,
Indonesia, with a population of 1.7 million in 2009. In the same
year, the total waste generated from all sources was approximately
4934 cubic meters per day. In this city, the Jatibarang landfill has
been in operation since March 1992. It covers 45 ha with a storage
capacity of 4.15 million cubic meters of waste, however, the
amount of waste in this landfill reached 5.75 million cubic meters
in 2009, therefore 1.6 million cubic meters of waste is beyond its
capacity. Therefore, reducing the volume of waste transported to
landfills is an important task for this city.
In 2006, CBWM was introduced in Bukit Kencana Jaya (located
in the Meteseh village of the Tembalang a sub-district of Semarang)
by a non-governmental organization (NGO) named BINTARI, under
the GTZ-ProLH (Indonesian-German Environmental Program facilitated
by the German Technical Cooperation [GTZ]). BKJ has 1016
households and covers about 200 ha in area. Here, the waste is
managed by an organization called Paguyuban Masyarakat Bukit
Kencana Jaya (PAGARWAJA)
