Abstract

Background: Renewable energy from biomass is one solution to reduce dependence on fossil fuels and the impact of carbon emissions. One form of renewable energy from biomass is briquettes. This study aims to analyze the effectiveness of using modern technology in the form of a briquette production machine set consisting of a grinder, extruder, and burner integrated with a wet scrubber innovation to reduce carbon monoxide (CO) emissions from rice husk combustion in the burner machine compared to the manual method. Methods: The research process was carried out through the stages of needs identification, CAD (Computer Aided Design)-based machine design, prototype production, and briquette performance testing using a Non-Dispersive Infrared (NDIR) analyzer. Findings: The test results showed that briquettes produced using the manual method had a higher density of 0.8 g/cm³ and produced an average CO emission of 220 ppm. These findings prove that mechanizing the process improves the physical quality of the briquettes while reducing CO emissions by around 39%. The integration of wet scrubber technology proved to be effective in absorbing additional exhaust gases and strengthening the environmentally friendly aspects of the combustion process. Conclusion: The conclusion of this study confirms that the use of integrated machinery not only improves briquette quality and energy efficiency, but also makes a significant contribution to carbon emission control efforts at the local level. Novelty/Originality of this Article: The novelty of this study lies in its comprehensive analysis comparing manual and mechanized methods using burner machines with integrated wet scrubbers in the context of rice husk briquette production.

Abstract

Background: Waste management in campus areas remains a significant issue, with trash bins often overflowing due to irregular monitoring and limited awareness among users. This problem is exacerbated by inefficient and energy-consuming traditional waste collection methods, alongside a common failure among students to properly separate waste at the source. The accumulation of unsorted waste not only degrades the campus environment but also represents a missed opportunity for effective recycling and resource recovery.  Existing smart bin solutions often focus on a single aspect, such as capacity monitoring or basic sorting, but rarely integrate a comprehensive, energy-independent system tailored for developing-world contexts. To address this multifaceted challenge, a new generation of smart and automated waste management systems is needed. This study introduces a novel solution designed to tackle these issues simultaneously. Methods: This study developed the Automatic Monitoring and Sorting Waste Bin (AMPIBI), an Internet of Things (IoT)-based device designed to automatically sort waste by category and monitor bin capacity in real time. The system integrates cloud-based applications, solar power, and multiple sensors, including moisture, metal, and ultrasonic sensors. The research followed a Research and Development (R&D) approach consisting of problem analysis, design, prototyping, and performance testing. Findings: Experimental results demonstrated that AMPIBI successfully classified waste into three categories: organic, non-metallic inorganic, and metal with an accuracy of 96.67%. The moisture sensor effectively distinguished organic from inorganic waste, the inductive sensor identified metals, and the ultrasonic sensor measured bin capacity. The monitoring system displayed real-time waste status via a cloud platform accessible through mobile devices. Conclusion: AMPIBI improves campus waste management by promoting proper waste disposal, reducing the need for manual intervention, and supporting environmentally friendly practices. Powered by solar energy, the system proved efficient and sustainable, making it a viable solution for cleaner and more energy-conserving campus environments. Novelty/Originality of this article: The novelty of this study lies in the integration of IoT technology, automated waste sorting, and renewable energy into a single system tailored for campus waste management. Unlike conventional bins, AMPIBI provides real-time monitoring, accurate waste classification, and independent solar-powered operation, offering an innovative model for sustainable waste management.

Abstract

Background: Indonesia produces more than 12.3 million tons of plastic waste each year, but only a mere 14% is recycled, leading to serious environmental concerns. On a global scale, solid waste totals 2.3 billion tons annually, with merely 61% being properly managed. This situation underscores the pressing demand for sustainable and effective technologies for handling plastic waste. Traditional pyrolysis is widely utilized but struggles with high energy requirements, needing temperatures between 700-900 °C, inconsistent heat distribution, and overall low efficiency in the process. Methods: This research introduces a Microwave-Assisted Pyrolysis (MAP) reactor that utilizes KOH-activated coconut shell biochar as a microwave absorber. It achieves a surface area greater than 800 m²/g, enabling effective absorption of 2.45 GHz microwaves. Non-toxic plastics like HDPE and PP are subjected to pre-treatment before undergoing MAP processing at temperatures of 450-600 °C for a duration of 10 minutes. An Internet of Things (IoT) system facilitates real-time monitoring of temperature, pressure, and flow rate to maintain precise control throughout the process. Findings: Results from experiments and a review of existing literature indicate that MAP is capable of transforming plastics into 70% bio-oil, 10% syngas, and 20% biochar, with energy consumption only at 0.8-1.2 kWh/kg—30-40% less than what traditional pyrolysis requires. The activation energy for coconut shell biochar drops significantly to 24.5 kJ/mol, compared to 84.2 kJ/mol found in conventional systems, showing better efficiency in volumetric heating. MAP has the potential to cut down plastic pollution by as much as 65% while generating bio-oil as an alternative fuel source, aiding the implementation of a circular economy and supporting Sustainable Development Goals 9, 12, and 13. Conclusion: MAP demonstrates a highly energy-efficient and scalable alternative for plastic waste valorization, reducing environmental pollution while generating useful byproducts and supporting sustainable development objectives. Novelty/Originality of this article: The research stands out by integrating KOH-activated coconut shell biochar with IoT-enabled real-time monitoring and an energy-efficient MAP method, providing a sustainable approach for recovering value from plastic waste beyond traditional pyrolysis.

Abstract

Background: The problem of waste management in Indonesia is still a serious challenge in realizing sustainable development. Although the government has set the Indonesia Clean Waste 2025 target target through Presidential Regulation No. 97 of 2017 concerning the National Policy and Strategy on Household and Similar Household Waste Management (Jakstranas), the implementation achievements at the regional level have not shown optimal results. Methods: This article uses a descriptive qualitative approach with content and interpretive analysis of secondary data from policy documents, performance reports, and academic publications for the 2019–2024 period. The analytical framework integrates the policy implementation effectiveness model of George C. Edwards III (1980) and the Collaborative Governance model of Ansell and Gash (2007). Findings: The results of the analysis show that the effectiveness of the implementation of waste management policies in Indonesia is still low to moderate. The main obstacles include non-participatory policy communication, limited regional resources and funding, weak inter-agency coordination, and low participation of the community and the private sector. However, some areas, such as Surabaya and Bekasi, have shown relatively successful collaborative practices in encouraging public participation and local innovation. Conclusion: The effectiveness of the implementation of waste management policies in Indonesia cannot be said to be effective, either in achieving national targets or in their implementation at the local level. Facilitative leadership, inclusive institutional design, and transparent policy communication are needed so that national and equitable targets can be implemented at the local level. Another thing is that the governance of waste management policies is highly dependent on the power of multi-level collaboration between the central government, local governments, the private sector, and the community. Novelty/originality of this article: This article offers the integration of two governance models—Edwards III and Ansell & Gash—in analyzing the effectiveness of environmental policy implementation in Indonesia and providing practical lessons from Singapore's experience to strengthen cross-sectoral collaboration in waste management.

Abstract

Background: The use of wet scrubbers and dry scrubbers in incinerators using activated carbon and zeolite adsorbents is applied to control SO₂ emissions, serving as environmentally friendly waste processing tools. Methods: The principle of this test is that the exhaust gas from burning plastic waste with an incinerator is washed in a wet scrubber using water. Any remaining gas emissions are absorbed by zeolite and activated carbon through a dry scrubber. Testing of SO₂ exhaust gas emission concentrations is carried out on the incinerator, wet scrubber, and final chimney. Findings: The SO₂ exhaust gas concentration in incinerator combustion was 0.9685 mg/Nm³, the concentration after scrubbing using a wet scrubber was 0.1389 mg/Nm³, and the concentration after scrubbing using a wet scrubber and dry scrubber was 0 mg/Nm³. Conclusion: The use of a wet scrubber is effective in reducing SO₂ exhaust gas emission concentrations. The use of a dry scrubber is also effective in further reducing SO₂ exhaust gas emissions to zero. Novelty/Originality of this article: The novelty of this study lies in the combined application of wet and dry scrubbers with activated carbon and zeolite to achieve complete elimination of SO₂ emissions from plastic waste incineration, demonstrating a practical environmentally friendly approach.
