Abstract

Limbah cair aren dan kotoran sapi merupakan substrat yang baik dalam pembuatan biogas, karena tanaman aren mengandung bahan organik yang tinggi dan kotoran sapi mengandung bakteri penghasil gas metan. Nilai rasio C/N dari limbah cair aren yaitu 15 dan  perlu dicampur dengan limbah yang memiliki rasio C/N lebih tinggi dari kotoran sapi yaitu 24. Penelitian dilakukan dengan proses anaerobic reactor. Penelitian ini menguji 5 variasi komposisi campuran kotoran sapi dan limbah cair aren yaitu 1 : 0,25, 1: 0,5, 1 : 0.75, 1 : 1 dan 1: 1,25. Masing-masing sampel dimasukkan ke dalam digester  dengan kapasitas 14 liter terdiri dari 11 liter campuran limbah dan 3 liter air, kemudian diinkubasi secara anaerob dalam ruang bersuhu antara 25oC – 30oC selama 50 hari. Parameter yang diukur berupa volume biogas, gas metan, nilai C/N rasio, pH dan suhu. Pengamatan volume gas dilakukan setiap hari dengan menggunakan gas holder dan konsentrasi gas metan diuji dengan Gas Chromatography (GC).  Hasil penelitian menunjukkan bahwa komposisi campuran kotoran sapi  dan limbah cair aren 1:1,25 menghasilkan biogas tertinggi dengan kadar gas metan 42%.

Abstract

This study investigates the implementation of community-based composting technology in low-cost rental apartments (Rusunawa) in Makassar City, Indonesia, as a solution for organic waste management and to enhance environmental awareness. Rusunawa, characterized by its vertical structure and tenant-based system, often faces waste management challenges due to limited space and varying levels of environmental awareness among residents. The study aims to apply composting technology through a community development strategy to address organic waste issues using accessible and affordable methods. A mixed-methods approach was employed, integrating quantitative analysis of compost quality with qualitative assessment of community responses across several stages of outreach: general counseling, floor-by-floor engagement, communal garden cultivation, neighbor-to-neighbor outreach, and media promotion. The results show that household waste from Rusunawa residents can be converted into compost with phosphorus (P) and potassium (K) levels exceeding the Indonesian National Standard (SNI), although nitrogen (N) and carbon (C) levels require improvement. Following the outreach process, more than 50% of residents demonstrated increased environmental awareness and actively participated in composting activities, with media-based and neighbor-to-neighbor outreach proving the most effective. To improve compost quality, extended composting time and nutrient supplementation are recommended. The study advocates for the establishment of community-based organizations to ensure the long-term sustainability and effective management of composting initiatives in Rusunawa.

Abstract

Illegal dumping represents a critical environmental and public health challenge in Indonesia, exacerbated by rapid urbanization, inadequate waste management infrastructure, and socio-cultural attitudes toward waste disposal. This study employs a descriptive literature review methodology to analyze illegal dumping trends over the past decade, synthesizing data from peer-reviewed articles, government reports, and case studies. Findings reveal the proliferation of unauthorized dumpsites, particularly in urban areas, alongside the increasing prevalence of plastic waste as a dominant component. Socio-economic factors such as poverty, limited access to formal waste management systems, and insufficient public awareness are identified as key drivers of this issue. Illegal dumping causes significant environmental degradation, including water contamination and ecosystem disruption, and poses substantial health risks through exposure to hazardous materials and vector-borne diseases. This research underscores the necessity for integrated interventions, highlighting the need for a comprehensive and multi-faceted approach to effectively tackle illegal dumping. Specifically, this entails strengthening regulatory frameworks, enhancing enforcement mechanisms, promoting community engagement, leveraging technological innovations, and making substantial investments in the strategic development of waste management infrastructure.

Abstract

Indonesia is an archipelagic country consisting of more than 17,500 islands. Urbanization and community agglomeration in urban areas in Indonesia are increasing the complexity of solid waste management in Indonesia. The old paradigm of 'collect-transport-disposal' waste management still occurs frequently in cities in Indonesia. This research is designed to be a systematic qualitative review. The relationships between good environmental governance and sustainable solid waste management are synthesized from a perspective of current conditions in Indonesia. The solution to sustainable waste management is generally carried out through well-organized waste management in an integrated manner from upstream to downstream with a 'cradle-to-grave' mindset, including the impacts that may arise therein. Implementing sustainable solid waste management requires commitment and support from all aspects of stakeholders. Good environmental governance is a comprehensive, dynamic, and complex concept that attempts to improve environmental conditions while promoting sustainable solid waste management. The results show that good environmental governance is very influential for sustainable solid waste management, but it still needs to be implemented optimally in Indonesia. Integration and synchronization of policies between the central government and local government must be further improved to implement good environmental governance.

Abstract

This study employed a mixed methods design to analyse university students' knowledge of the Sustainable Development Goals (SDGs), their practices toward carbon reduction, and their innovative ideas for carbon mitigation. The main aim of this research is to examine how students’ understanding of the SDGs relates to their actual carbon reduction practices and to identify innovative solutions they propose for environmental sustainability. The research surveyed 123 students from 11 academic programs across seven universities in Eastern Indonesia. Quantitative results showed no significant differences in carbon reduction practices among students from various academic programs (F = 0.720; p = 0.674). A significant but very weak correlation was found between SDG knowledge and positive practices toward carbon reduction (r = 0.152; p = 0.047). The qualitative analysis identified eight themes of innovation, with a majority focusing on reforestation (33%) and the 3R waste management system (31%). Notably, technology-based ideas constituted only 8% of the responses. The study's main limitations include a sample imbalance, with 39.5% of participants from Environmental Engineering, and the use of convenience sampling, which necessitates caution when generalizing the findings. The results suggest the need for a holistic approach that integrates education, practical implementation, supportive facilities, and technological innovation. Recommendations include: (1) integrating SDGs into the curriculum, (2) developing a gamified, collaborative digital platform, and (3) fostering interdisciplinary collaboration to create contextual solutions

Abstract

A significant amount of global greenhouse gas (GHG) emissions comes from Indonesia, largely driven by deforestation and land degradation. As a developing nation, it is also dealing with the growing pressures of urban expansion. This study assesses the distribution of carbon stock in Parepare City, South Sulawesi, Indonesia. Notably, Parepare City has not yet experienced extensive land-use transformations, retaining substantial carbon stock, which positions it as a proactive case study for preventing future carbon loss amidst ongoing urbanization. Using the InVEST Carbon Storage and Sequestration model with SPOT 7 satellite imagery (2016) and global carbon density data, the research quantifies carbon storage across various land use/land cover (LULC) types. Analysis reveals natural ecosystems, particularly mixed forests and fields, hold the highest carbon storage potential. The total estimated carbon stock in Parepare City is 1,456,909.41 Mg C. These findings emphasize the urgent need for climate-responsive land management, including forest conservation, and urban greening, to enhance local carbon sinks and support Indonesia's climate change mitigation goals. This assessment provides crucial insights for urban planners and policymakers to balance growth with ecosystem conservation for a susta00inable future.
