Abstract

The ever-increasing volume of municipal waste in Yogyakarta brings overload capacity problems to the Piyungan Landfill. This circumstance results in environmental pollution which harms the local residents. Therefore, this study was conducted to determine the impact of pollution in the Piyungan Landfill from an economic, environmental, and social perspective. Furthermore, this study aims to formulate a waste management strategy in the landfill using the fishbone analysis to find out the root causes of existing problems, the stakeholder analysis method to determine the role of each stakeholder involved, and the SWOT analysis method to determine potential strategies for waste management. From those analysis methods, it is concluded that there are six root causes in the landfill, namely the waste management process, the amount of waste, landfill facilities, the technology used, the implementation process, and government policies. This study recommends several waste management improvements from the combination of strengths and opportunities factors (SO Strategy). The combination of these strategies includes: (1) establishing cooperation policies with foreign parties. (S1, O1); (2) optimizing budget and waste management technology. (S2, O2); (3) providing transportation facilities and technology to optimize the recycled waste business. (S3, O2, O3); and (4) maximizing resources to optimize the recycled waste business. (S4, O3). These strategies are expected to be able to increase the capacity and capability of the Piyungan Landfill in managing waste and overcoming environmental pollution.

Abstract

Urban household waste management in developing countries faces increasing complexity due to population growth, land constraints, and socio-environmental considerations. This study proposes a comparative evaluation of the Analytic Hierarchy Process (AHP) and Fuzzy AHP to support decision-making in selecting sustainable household waste treatment alternatives in Umbulharjo Sub-district, Yogyakarta City, Indonesia. Five sustainability criteria and five alternative treatment methods were identified through expert consultation and literature review. Primary data were collected from 20 household respondents using structured questionnaires. The AHP method applied a crisp pairwise comparison scale, while Fuzzy AHP incorporated linguistic assessments converted into Triangular Fuzzy Numbers to better handle uncertainty and subjectivity. The results demonstrate that while AHP prioritizes the burning method due to perceived simplicity and feasibility, Fuzzy AHP reveals a stronger preference for “Sorting, Hoarding, and Selling,” reflecting the community’s implicit environmental and economic concerns. The divergence in outcomes highlights the limitations of deterministic assessments in complex socio-technical systems and underscores the added value of fuzzy logic in capturing nuanced stakeholder preferences. By integrating quantitative and qualitative criteria within a hierarchical decision framework, this study contributes to the development of more context-sensitive and adaptive decision-support tools. The findings offer practical guidance for municipal authorities and urban planners seeking to align waste management strategies with cleaner production principles. The proposed methodological framework enhances transparency, inclusiveness, and responsiveness in sustainability assessments, supporting the transition toward more resilient and community-driven urban waste systems.
