This study aims to analyze the effect of renewable energy, energy consumption, and Gross Domestic Product (GDP) per capita on carbon dioxide (CO2) emissions in Indonesia for the period 1995-2024. This study uses secondary data over time (time series) with the Ordinary Least Square (OLS) multiple linear regression analysis method corrected using the Newey-West Heteroskedasticity and Autocorrelation Consistent (HAC) approach. The results show that renewable energy does not have a significant effect on CO2 emissions, which is caused by the still low share of renewable energy in the national energy mix which only reaches 10.95% in 2024. Energy consumption has a positive and significant effect on CO2 emissions, where every 1% increase in energy consumption increases CO2 emissions by 84.23%. Gross Domestic Product (GDP) per capita has a positive and significant effect on CO2 emissions. Every 1% increase in GDP per capita increases CO2 emissions by 35.03%, indicating that Indonesia remains on the EKC curve. Simultaneously, all three variables have a significant effect, with an adjusted R-squared value of 53.63%. This finding confirms that Indonesia's energy mix, still dominated by fossil fuels, is a major factor in high carbon emissions. Comprehensive energy efficiency policies, accelerated renewable energy transitions, and greener and more sustainable economic growth strategies are needed.

Illegal logging is a serious environmental problem in Indonesia due to its direct impact on forest destruction, biodiversity loss, and increased carbon emissions. The Indonesian government has established various public policies and legal instruments to address illegal logging practices, such as the Forestry Law, the licensing system, and strengthening law enforcement agencies. However, the effectiveness of these policies remains a concern, given that illegal logging cases continue to occur in various regions. This study aims to assess the effectiveness of public policies in enforcing environmental law, focusing on illegal logging cases in Indonesia. The method used in this study is a normative juridical approach by examining regulations, government policies, and secondary data from reports from relevant institutions and previous research results. Analysis shows that despite comprehensive public policy design, its implementation still faces various obstacles, such as weak oversight, poor coordination between institutions, limited human resources, and corrupt practices. Furthermore, social and economic factors in communities surrounding forests also influence the success of environmental law enforcement. Therefore, strengthening law enforcement agencies, transparency and accountability, and active community involvement in forest management are essential. With these improvements, public policy is expected to be more effective in preventing and combating illegal logging for the sake of environmental sustainability in Indonesia.

Self-Compacting Concrete (SCC) requires a high cement content, which contributes to increased carbon emissions; therefore, this study evaluates the effect of partial cement substitution with fly ash (5%, 10%, and 15%) and the addition of Polyethylene Terephthalate (PET) waste (0.5% and 0.7%) on the mechanical properties of SCC with a target strength of f’c 30 MPa. The research employed laboratory experimental methods, including fresh concrete tests (slump flow, L-box, and V-funnel) and hardened concrete tests (compressive, tensile, and flexural strength) at 7 and 28 days. The results indicate that fly ash substitution enhances compressive strength, with the highest value of 49.59 MPa achieved at 5% fly ash at 28 days, exceeding normal concrete (34.73 MPa). The addition of PET tends to reduce compressive strength due to increased porosity; however, it significantly improves flexural strength, as the combination of 5% fly ash and 0.5% PET achieved 4.7 MPa compared to 2.9 MPa for normal concrete. Overall, the combination of fly ash and PET waste shows potential for application in structural elements requiring high flexural performance.

The increasing demand for housing in tropical regions requires building materials that are fast to apply, environmentally friendly, and resilient to extreme climate conditions as well as disaster risks. Conventional interlocking bricks are often chosen for their ease of construction, yet they still face challenges such as moisture and early cracking. This study proposes the innovation of the Hybrid Living Green Brick, a combination of lightweight bricks made from rice husk ash and fly ash waste (FRCB) with a biological layer of cyanobacteria. FRCB improves compressive strength by approximately 30% with the addition of 5% rice husk ash, achieving 65 kg/cm², thereby meeting Class 50 requirements (≥50 kg/cm²) according to SNI-15-2094-2000. The incorporation of 3% cyanobacteria provides an additional though not significant strength improvement, while still within the Class 50 category. It also reduces brick weight by 4.3%, with further optimization potential through cyanobacteria integration, and lowers carbon emissions from the firing process. Cyanobacteria induce the formation of CaCO₃ layers that seal pores, reduce water absorption by an average of 10%, and provide self-healing properties for microcracks. Preliminary observations indicate that FRCB offers stable mechanical performance, while biological activity was observed on the 7th day with the formation of pale-white mineral layers continuing until the 28th day. This hybrid innovation shows potential to support sustainable and disaster-resilient tropical construction by combining the mechanical strength of waste-based materials with the biological durability of cyanobacteria against extreme climates. Despite challenges related to moisture control and production standardization, the Hybrid Living Green Brick concept opens new pathways for developing environmentally friendly construction materials that are more adaptive to disaster-prone tropical conditions.

The analysis methods used in this study include a case study on the use of closed-loop recycling and an evaluation of biopolymer performance across various industries, both of which are important components in the transformation of the manufacturing industry toward a circular economy. The research findings indicate that recycled materials can reduce carbon emissions by thirty to fifty percent and save production costs by fifteen to twenty-five percent. Artificial intelligence-based sorting technology improves sorting efficiency to 95 percent, and closed-loop recycling maintains the mechanical properties of materials up to 90 percent after four cycles. The degradation rate of biopolymers like PLA and PHA reaches 60-80% within six months, although production costs are still 2-3 times higher. The integrated approach increases resource efficiency by 45% and reduces waste by 60%. To achieve successful implementation, Extended Producer Responsibility (EPR) policies, strategic infrastructure investments, and collaboration from various parties thru the triple helix model must work together.

Rapid global population growth has led to climate change and agricultural land degradation, posing significant challenges to the stability of global food security. The traditional livestock sector is known to absorb high levels of greenhouse gas emissions that can accelerate natural resource degradation and require innovative and sustainable approaches to meet the demand for animal protein. This study aims to analyze the contribution of cultured meat technology as an ethical and environmentally friendly alternative to improving global food security. This study uses a desk study method that addresses the technical, social, economic, and ethical aspects of cultured meat production. The analysis results indicate that the application of this technology has the potential to reduce land use and carbon emissions by up to 70% compared to conventional livestock systems, in addition to reducing animal suffering and the risk of zoonotic disease transmission. However, its application still faces several obstacles, such as high production costs, dependence on whey-based culture media, and difficulties in halal certification and public acceptance. These findings underscore the importance of synergy between scientists, governments, and religious authorities to ensure the safety, effectiveness, and equivalence of technology with ethical principles and socio-cultural values. With strong regulatory support and ongoing research, cultured meat technology has the potential to be a strategic solution for building a resilient, equitable, and environmentally responsible global food system.

This study explores the urgency of enacting a specific Electronic Waste Management Law in Indonesia as a legal foundation to support the achievement of net zero emissions. Using a normative juridical approach, the research analyzes existing legal shortcomings, the application of the Extended Producer Responsibility (EPR) principle, and comparative insights from international e-waste regulatory frameworks. The findings indicate that current environmental regulations, such as Law No. 32 of 2009 on Environmental Protection and Management and Government Regulation No. 101 of 2014 on Hazardous Waste Management, do not explicitly regulate electronic waste. As a result, e-waste management remains fragmented and largely handled by the informal sector without adequate supervision or accountability mechanisms. Therefore, the establishment of a comprehensive E-Waste Law is crucial to enhance Indonesia’s legal structure, substantive norms, and legal culture in supporting a sustainable circular economy. Through the implementation of EPR and shared responsibility among producers, consumers, and government institutions, the law can function as a strategic tool to minimize electronic waste generation, improve recycling efficiency, and reduce carbon emissions. Such legal innovation would reinforce Indonesia’s environmental governance and accelerate progress toward its national goal of achieving net zero emissions by 2060.

Overall, the research affirms that these practices are essential tools for confronting and mitigating the environmental pollution challenges of modern industries, while simultaneously fostering sustainable economic growth and long-term environmental protection.

Green Open Space (GOS) is an essential element in urban spatial planning that functions to maintain air quality and ecosystem balance. This research aims to analyze the influence of GOS on the concentration levels of Carbon Dioxide (CO2​) in the urban area of Jayapura City. The study locations were focused on two areas with distinct characteristics: Jalan Sam Ratulangi, which has high vegetation coverage, and Jalan Percetakan, which is dominated by built-up areas and dense commercial activity. The methods used include spatial analysis utilizing Landsat 8 satellite imagery Band 4 (Red) and Band 5 (NIR) to calculate the NDVI (Normalized Difference Vegetation Index), a vegetation time series analysis from 2019–2024, and direct CO2​ concentration measurements taken at three different times (morning, noon, afternoon). The data was processed using ArcGIS with the Kriging Interpolation method to generate spatial distribution maps of CO2​ in both locations. The results show that Jalan Sam Ratulangi has a GOS area of 6.13 ha (94%), while Jalan Percetakan has only 2.95 ha (31%). This difference significantly impacts CO2​ levels, with an average concentration of 484 ppm at Sam Ratulangi, which is lower than Percetakan's average of 567 ppm. The highest CO2​​ value at Percetakan reached 649 ppm during the afternoon, whereas Sam Ratulangi recorded only 488 ppm. This study proves that the wider and healthier the GOS, the lower the CO2​​ concentration detected. These results demonstrate that vegetation plays a significant role in reducing carbon emissions in urban areas, supporting the crucial role of GOS in maintaining air quality and supporting sustainable urban development in Jayapura City.

Climate change driven by global warming has prompted companies to enhance transparency regarding the environmental impacts of their operational activities, particularly in the disclosure of carbon emissions. Such disclosure is essential to address stakeholder demands and to gain social legitimacy, in accordance with stakeholder theory, which serves as the foundation of this study. This research aims to empirically examine the effect of environmental performance, profitability, and institutional ownership on carbon emission disclosure among non-financial companies listed on the Indonesia Stock Exchange. The population of this study comprises non-financial companies listed on the Indonesia Stock Exchange from 2020 to 2023. The sample was selected using a purposive sampling technique, resulting in 332 observations from 115 companies. The data analysis method employed is multiple linear regression analysis. The results reveal that environmental performance has a positive effect on carbon emission disclosure, indicating that the better the company’s environmental performance, the higher the level of carbon emission disclosure. Profitability and institutional ownership, however, have no significant effect on carbon emission disclosure.

This study aims to analyze the influence of green financing, industrialization level, and fossil energy consumption on carbon emissions in Indonesia for the period 2018–2023. The method used is multiple linear regression with the Ordinary Least Squares (OLS) approach based on time series data. The dependent variable used is carbon emissions, while the independent variables include green financing, industrialization level, and fossil energy consumption. The results of the analysis show that both simultaneously and partially, the three independent variables do not have a significant effect on carbon emissions. The coefficients of green financing and industrialization tend to be positive, while fossil energy consumption is negative, but all are not statistically significant. These findings indicate that green financing policies, industrial development, and fossil energy consumption during the study period have not had a significant impact on carbon emissions in Indonesia. This study recommends the need to extend the observation period, add relevant variables such as the renewable energy mix, and optimize the implementation of green energy and financing policies to support carbon emission reduction in the future.

This research investigates the integration of renewable energy systems within coastal conservation areas through public-private partnership (PPP) frameworks to achieve dual objectives of environmental sustainability and economic development. The study addresses the critical challenge of balancing energy infrastructure development with ecological preservation in sensitive coastal ecosystems, where biodiversity and community livelihoods are often at risk due to increasing industrial and urban pressures. A mixed-methods approach is employed, combining case study analysis, stakeholder interviews, and economic modeling, to generate a comprehensive perspective on the opportunities and constraints of renewable energy deployment in these regions. Case studies highlight successful international practices of PPPs that have facilitated renewable energy projects while safeguarding marine and coastal ecosystems. Stakeholder interviews with government agencies, local communities, and private sector representatives reveal the importance of transparent governance, shared responsibility, and inclusive participation in ensuring long-term project sustainability. Economic modeling further demonstrates that well-structured PPP models can reduce implementation costs by 30–40% while adhering to biodiversity conservation standards and regulatory frameworks. Findings underscore that renewable energy projects, when embedded within collaborative governance structures, not only contribute to reducing carbon emissions but also create employment opportunities, stimulate local economies, and enhance community resilience. This study contributes to the sustainable development literature by providing an actionable framework for integrating renewable energy infrastructure in environmentally sensitive areas through PPPs. The proposed framework emphasizes adaptive policy design, capacity building, and equitable benefit-sharing, offering practical insights for policymakers, practitioners, and researchers seeking to reconcile energy needs with ecological protection in coastal regions.

The use of palm oil waste as boiler fuel is one of the innovative solutions in supporting the use of renewable energy while reducing the environmental impact of palm oil industry waste. Waste such as palm shells, mesocarp fibers, and empty oil palm bunches have high energy potential through direct combustion and other thermal technologies. This study aims to evaluate the potential use of palm oil waste as boiler fuel based on its calorific value, combustion efficiency, and environmental impact. The methods used include analysis of the physical and chemical characteristics of waste, boiler performance tests, and exhaust gas emission evaluation. The results show that palm oil waste has a high calorific value (15–20 MJ/kg), which makes it an efficient alternative fuel. In addition, the use of this waste is able to reduce dependence on fossil fuels while minimizing carbon emissions, thereby supporting the greenhouse gas emission reduction target. From an operational perspective, the use of palm oil waste in industrial boilers can increase combustion efficiency by up to 75–85%, depending on fuel conditions and boiler design. This makes palm oil waste not only economically valuable, but also strategic in supporting the transition to clean energy. Another advantage is that waste management becomes more targeted, because solid waste that is usually only an environmental burden can be reused as an energy source. However, some of the challenges that need to be considered include relatively high ash levels, the potential for corrosion in boiler equipment, and the need for emission control technology to comply with environmental standards. With the right mitigation strategy, palm oil waste can be processed into sustainable and environmentally friendly energy.

Urban logistics is a significant source of carbon emissions in Indonesia, and effective decarbonization strategies are required. EVs offer a promising solution, but their impact requires quantitative evaluation within the local context. This study analyzes the effect of adopting an electric van fleet on total well-to-wheel carbon emissions within an urban distribution network in Indonesia. This study employs a comparative case study method. A baseline scenario consisting of 25 diesel vans is compared to an intervention scenario where electric vans replace the entire fleet. The emission analysis was conducted using the WtW framework, utilizing specific emission factors for diesel fuel from the IPCC (2006) and the Java-Madura-Bali (JAMALI) grid emission factor from IESR (2023) to ensure contextual relevance. The transition to an electric fleet successfully reduces the total well-to-wheel carbon footprint by 13.63%. This reduction is equivalent to an absolute CO2 emission decrease of nearly 3 tons of CO₂ per month. Nevertheless, indirect emissions from electricity generation still contribute a significant carbon footprint, indicating that the national energy mix is highly dependent on the environmental benefits of EVs. This study concludes that fleet electrification is a viable and effective decarbonization strategy for Indonesia’s logistics sector, even with the current state of the electricity grid. However, fleet decarbonization efforts must run in parallel with policies for a national transition toward renewable energy to maximize the emission reduction potential of electric mobility. Future research should include the total cost of ownership (TCO) and life cycle assessment (LCA) for a more holistic evaluation.

Firm value is a crucial indicator that provides information to investors for making investment decisions. Today, investors also consider a company’s commitment to environmental issues, especially in the energy sector, which significantly contributes to carbon emissions. This study aims to empirically examine the effect of carbon emission disclosure and green investment on firm value. The theoretical framework employed includes signaling theory and legitimacy theory. Firm value is measured using the Tobin’s Q ratio. Carbon emission disclosure is measured through content analysis based on the GRI 305 standards, while green investment is measured using the PROPER rating issued by the Ministry of Environment and Forestry. This study also includes three control variables: firm size, leverage, and profitability. The analytical method used is multiple linear regression, with secondary quantitative data collected from companies’ annual reports and sustainability reports. The sample consists of 69 companies with a total of 271 observations. The findings reveal that carbon emission disclosure has a positive effect on firm value, while green investment does not have a significant effect on firm value. This research is expected to contribute to the development of signaling and legitimacy theories and serve as a practical reference for investors in considering environmental aspects when making investment decisions.
