Abstract

Rapid urbanization has accelerated the degradation of subak rice fields in Bali, manifested through pollution of irrigation channels and reduced agricultural productivity. This study assessed the extent and characteristics of land degradation in South Denpasar and formulated sustainable management strategies for restoring the ecological and cultural integrity of the subak system. The Logical Framework Approach (LFA) was applied to identify key problems, analyze causal relationships, and develop measurable strategies. Data were obtained through questionnaires, interviews, field observations, and document analysis. Results showed that approximately 87 hectares of subak land were lost within five years, driven by weak spatial enforcement, domestic and industrial waste pollution, and limited farmer regeneration. The study formulated five priority strategies: (1) enforcement of land use regulations, (2) economic incentives for conservation farming, (3) integration of Tri Hita Karana values, (4) farmer capacity building through digital technology and (5) improved irrigation maintenance. The research highlights that sustaining the subak system requires a multi dimensional management approach integrating ecological restoration, socio economic empowerment, and cultural revitalization. Adoption of this framework by local authorities can enhance urban land governance, strengthen farmer livelihoods, and preserve Bali’s cultural agricultural heritage amid ongoing urban pressures.

Abstract

An effective waste collection system is an essential step in plastic waste handling and impacts positively on recycling rates. In the era of digital technology transformation, digital-based plastic waste collection and recycling have emerged to offer innovative solutions for more effective plastic waste management from upstream to downstream which contribute to the Sustainable Development Goals target. However, this solution has not been widely implemented in Indonesia. Therefore, this study aims to synthesize the role of digitalization of waste collection in accomplishing the Sustainable Development Goals. This study employed with a qualitative approach through semi-structured interviews. Bibliometric analysis using VOSviewer version 1.6.20 was conducted to map prior studies on the digitalization of waste collection in the context of achieving the Sustainable Development Goals. This study confirms that the digitalization of waste collection contributes to the achievement of the three pillars of the Sustainable Development Goals, example economics, social, and environmental pillar.
