getting service from CWTF and discard his/her garbage to ditch or burn. In short, in its
implementation, operators have three function as garbage collectors, for separating inorganic
waste, and attract direct retribution from the community
Characteristic of Waste at Source
Characteristics of waste at source is measured from the garbage that came from some of
the selected home directly to find out waste generation per person per day. Measurement
characteristics of waste had done in the settlement include the household and non residential.
Based on the waste generation measurements and collection methods, according to SNI 36-
1991-03 M, obtained in six households with 4 low income households, 1 middle-income
households, and 1 high-income households. Sampling was held during 8 days with the time made
in the same range each day, at 9 am – 11 am WIB. Measurement results as shown in Figure 2a
for residential and Table 1 for non residential that includes shops and a primary school. For low
income households with 6-9 members of the family life, has waste generation is 1.24 l/o/h. Midle
income household (5 people / home) has 1.73 l/o/h. Meanwhile, high income households (3
people / house) has 2.9 l/o/h. The composision of waste generation at source is 72% organic
waste and 15% plastic (Figure 2b). The average density of household waste generation is 100

Non residential waste generation consists of primary school and shop. Shop (49 m 2 ) has four
worker. Waste source originated from the rest of the trade, such as plastic wrapping. Average of
waste generation is 2.81 l /worker/day. It’s in the range of standard waste generation for shop of
2.5 – 3.0 l /worker/day (Tchobanoglous, 1993). Meanwhile, primary schools (1600 m 2 ) have 250
students. Source of waste originated from the rest of the students and office waste, not including
garden waste. Average volume of waste generated at 0.13 l /student/day where the standard for
school waste generation is 0.1 - 0.15 l /o/h (Tchobanoglous, 1993).However, volume of waste
