Open burning of household waste remains the dominant waste disposal practice in rural areas of Indonesia, posing significant risks to public health and environmental quality. This community service activity aimed to provide an innovative, low-smoke waste combustion solution — the rocket stove incinerator — to the residents of Dusun Allukeke, Desa Belapunranga, Kecamatan Parangloe, Kabupaten Gowa. A baseline survey conducted during PBL 1 revealed that 87.6% of households disposed of waste through open burning. An asset-based community development (ABCD) approach was adopted, engaging community members at every stage from planning, construction, to utilisation. The rocket stove was constructed over three days using locally available materials and was demonstrated to significantly reduce visible smoke emissions compared to conventional open burning. The technology works through a vertically insulated combustion chamber that promotes near-complete combustion, reducing waste volume by 50–90% while suppressing particulate matter and hydrocarbon emissions. Community participation strengthened local ownership of the solution. This activity demonstrates that appropriate technology co-constructed with communities can serve as a practical, sustainable, and replicable model for rural waste management.

Rapid urban growth is often linked to the narrative of sustainable development, yet the reality is that fundamental issues remain in the management of urban waste. This paper aims to examine the gap between the concept of a sustainable city and sub-optimal waste management practices. Through a normative legal approach involving an analysis of legislation and relevant literature, it has been found that the implementation of waste management policies continues to face various challenges, such as weak law enforcement, a lack of policy integration, and low levels of public participation. On the other hand, the use of the label ‘sustainable city’ tends to be symbolic and does not yet reflect comprehensive practices. This paper positions the issue of waste as a key indicator in assessing urban sustainability. The novelty of this study lies in its critical approach, which links the discourse on sustainability with the contextual realities of waste management, thereby offering a more reflective and distinct perspective from previous studies.

The waste problem in Indonesia has now reached a critical stage and has become an increasingly serious environmental issue. The ever-increasing volume of waste is not being managed effectively, leading to various negative impacts, particularly environmental pollution. This study aims to examine the state of waste management in Indonesia and its impact on water pollution from the perspective of the Sustainable Development Goals (SDGs). The method used is descriptive qualitative research through a literature review utilizing various sources such as journals, official reports, and legislation. The results indicate that the majority of waste originates from household activities, while management practices remain rudimentary, such as the “collect-transport-dispose” method and open dumping. This situation leads to waste accumulation, which contributes to water pollution, deteriorating environmental quality, and increased health risks for the community. Furthermore, suboptimal waste management also poses a challenge in achieving sustainable development goals, particularly regarding responsible consumption and access to clean water and sanitation. Therefore, improved efforts are needed through the application of the reduce, reuse, recycle (3R) principles, increased public awareness, and the active role of the government and the private sector in providing a sustainable waste management system. With the right measures, it is hoped that the waste problem in Indonesia can be reduced and the environment preserved.

Kesadaran dan kepedulian masyarakat terhadap lingkungan telah mendorong munculnya berbagai inisiatif pengelolaan sampah berbasis komunitas, salah satunya melalui mekanisme bank sampah.
