Abstract

This study aims to analyze the landfill design based on the estimated methane gas emissions at the Jatibarang Landfill, Semarang City, using the Landfill Gas Emissions Model (LandGEM) software version 3.03 and evaluate its potential utilization as an energy source. The study uses a quantitative approach utilizing mathematical modeling to estimate the estimated gas emissions from the landfill. The results show that the potential for electrical energy that can be generated from landfills is high enough to be recommended for management using the concept of Waste to Energy (WTE) into electrical energy. The recommendation that will be discussed is the management of methanogas emissions by being used as electrical energy, emphasizing infrastructure improvements for optimal energy production and reducing greenhouse gas emissions. This study could also incorporate real-time monitoring of gas emissions and energy production to better understand the dynamics of waste decomposition and the benefits of electricity generated from waste could foster community support for PLTSa initiatives.

Abstract

This study aims to evaluate the potential of various waste management scenarios to reduce greenhouse gas (GHG) emissions in urban settings, focusing on the Jongkong landfill in Bangka Tengah Regency, Indonesia. The methodology involved collecting data on waste generation, composition, and current practices from municipal records, categorizing municipal solid waste (MSW) into organic, plastic, and other waste types. Four waste management scenario scenarios were modeled: the Business as Usual (BAU) scenario, which reflected current disposal practices, a Biological Scenario that processed organic waste through anaerobic decomposition to produce biogas, and a thermal scenario that utilized pyrolysis for plastic waste to recover energy. The combined scenario showed the best emission efficiency with the lowest net emission value, which is 10,436.22 kg CO2 eq per year, compared to other scenarios. The biological scenario showed a better net emission than the existing one (17,467,402.15 kg CO2/year), supported by the application of anaerobic digestion (AD) which helps reduce emissions. The thermal scenario also showed good performance by generating net emissions of 2,645,866.25 kg CO2-eq/year, driven by the contribution of pyralysis and the reduction of emissions from open burning and indiscriminate disposal. This study not only enhances understanding of GHG emission reduction strategies but also contributes to the development of tailored waste management policies that can be implemented in similar urban contexts. This novel approach highlights the synergistic benefits of combined waste treatment technologies, offering actionable insights for policymakers and contributing localized data to enhance sustainable waste management practices in Indonesia.

Abstract

Municipal waste production in Indonesia is rapidly increasing due to population growth and economic development, contributing significantly to greenhouse gas (GHG) emissions. This research aims to develop effective waste management scenarios for Pekanbaru City, focusing on reducing GHG emissions through integrated treatment methods. Employing a comprehensive methodology, the study estimates GHG emissions from various waste management practices, including biological, thermal, and mixed methods. The research utilizes a basic model to calculate emissions based on activity data and emission factors, exploring current practices and innovative strategies like Black Soldier Fly (BSF) larvae for organic waste treatment. Findings reveal that the Mix scenario, which combines multiple waste management processes, results in the most significant reduction of GHG emissions, achieving a net emission of 112,985.89 tons of CO?-eq/year, compared to the existing scenario with 637,864.33 tons of CO?-eq/year. The study identifies key emission hotspots, emphasizing the need for improved management of organic waste through composting and recycling. The implications of this research highlight the importance of adopting integrated waste management strategies to mitigate GHG emissions effectively. The findings provide actionable insights for policymakers, promoting sustainable practices aligned with the 3R hierarchy (reduce, reuse, recycle) and supporting targeted interventions that can enhance environmental sustainability in urban settings.

Abstract

The palm oil industry produces large volumes of palm kernel shell (PKS) solid waste, most of which has been utilized as biomass, but some of which has the potential to increase greenhouse gas emissions if not managed optimally. Pyrolysis of PKS to biochar offers a sustainable solution to reduce environmental impacts while producing value-added products. This study aims to compare various pyrolysis methods and operational conditions used in the conversion of PKS and other palm oil wastes, and to identify the main results, applications, and environmental benefits of each approach. The findings of this study are that the optimal conditions for biochar production are slow pyrolysis (400–600°C, 30–90 minutes residence time) with a yield of 33–52%. Biochar can be applied in Soil Improvement and Agriculture Increasing soil fertility and carbon sequestration (CSP 0.63 kgCO?/kg PKS), Air Treatment and Pollutant Adsorption, Energy and Fuel (made into briquettes), Health and Safety (Reducing environmental toxicity), Industrial and Material Applications (Raw material for activated carbon production). Comparing to inceneration and gasification, pyrolysis of PKS offers superior environmental sustainability when biochar is sequestered or utilized in high-value applications. Its dual benefits of renewable energy recovery and carbon storage address both immediate energy needs and long-term climate change mitigation.

Abstract

Indonesia has set a target to achieve Net Zero Emissions (NZE) by 2060 and a 52% renewable energy share by 2030. Geothermal energy, with 29.5 GW potential, is critical, yet environmental performance of technologies remains poorly characterized, hindering sustainable decisions. This systematic review analyzes life cycle assessment (LCA) studies on binary, flash, and dry steam geothermal technologies. Scopus and Google Scholar searches using keywords "geothermal power plant" and "life cycle assessment" yielded 30 studies (2013–2025). Environmental burdens vary by technology, geology, design, and operations. Binary systems face high impacts from drilling, steel construction, and working-fluid leakage (up to 64% of global warming potential). Flash systems show major CO? and H?S emissions, reducible by 78% via abatement or hybrid flash-binary setups. Dry steam plants are dominated by non-condensable gas (NCG) emissions unless hybridized with Enhanced Geothermal Systems (EGS) or Combined Heat and Power (CHP), shifting hotspots to construction. Findings offer Indonesia actionable insights: select cleaner configurations, optimize drilling, deploy emission controls, and prioritize low-global-warming-potential fluids. This synthesis of site-specific LCAs creates a framework identifying hotspots and pathways, supporting evidence-based policies for sustainable geothermal expansion in Indonesia's energy transition.
