Abstract
Boarding houses (student-rented rooms) in Indonesia are generally grouped into two different types, namely Non-Exclusive Boarding
House (NEBH) and Exclusive Boarding House (EBH). The different types of boarding house will affect the patterns of solid waste generation.
This study aims to determine the level of participation and willingness of the students living in these two types of boarding houses to separate
their waste. Based on findings of this study, a waste management system can be designed, including the analysis of solid waste generation,
waste composition, and characteristics of residents. The research began with waste generation sampling in the boarding houses around campus
of three universities in Yogyakarta, Indonesia. The residents’ characteristics were identified using questionnaires. The weight and volume of
waste generated in EBH were found slightly larger than NEBH namely 0.36 and 0.31 kg/person/day (weight) and 2.38 and 2.04
liter/person/day (volume), respectively. Regarding the waste composition, a slight difference was observed for organic waste (19.30% and
1
7.51%) and plastic waste (28.08% and 27.74%) for the NEBH and EBH, respectively. In addition, the level of willingness to separate the
waste for students in NEBH was higher than those in EBH with scores of 61% and 41%, respectively. It was concluded that students in
NEBH generate more waste than EBH, especially for two main types of waste, but the level of participation and willingness to waste
separation in NEBH residents was higher than EBH residents. The results of this study are essential to be considered
