Social Engineering in Promoting Behavioral Change within the Community through Source-Based Waste Sorting: A Study in Baha Village, Mengwi District, Badung Regency, Bali, Indonesia

Abstract

This study aims to describe the social engineering efforts used to encourage behavioral change within the community regarding source-based waste segregation in Baha Village, Mengwi District, Badung Regency, Bali, Indonesia. The study employs a descriptive approach, observing waste management practices within the village based on observed conditions and experiences related to waste segregation activities. The findings indicate a shift in community habits: residents have moved from disposing of mixed waste sometimes even burning it to segregating waste into organic, inorganic, and residual categories right at the household level. This transition occurred gradually, as some residents initially perceived segregation as a burdensome task that required multiple, separate waste bins. Social engineering was implemented through village-level regulations stipulating that unsorted waste would not be collected alongside repeated public outreach, the strengthening of "Waste Banks" (community-based waste collection centers), and the integration of these practices into daily life. The presence of Waste Banks has also provided economic value to certain types of inorganic waste, serving as an additional incentive for the community. Nevertheless, long-standing habits and the perception that segregation creates extra work remain significant obstacles. These findings demonstrate that fostering environmentally responsible behavior requires more than just regulations; it necessitates a deep understanding, consistent implementation, tangible benefits, and active community engagement. Consequently, the sustainability of source-based waste segregation relies on a synergy between village policies, public outreach, waste management facilities, and collective participation from the residents.
