Abstract

Climate change due to drastic increases in greenhouse gas (GHG) emissions has damaged marine ecosystems through warming and acidification. This study aims to analyze the conformity of international law and the implementation of Indonesian national regulations in an effort to protect the marine environment from the impacts of anthropogenic GHG emissions. Using normative legal research methods, this study applies legislative and conceptual approaches to examine UNCLOS 1982, the Paris Agreement, the Environmental Management Law, and Presidential Regulation No. 110 of 2025. The results show that Article 192 of UNCLOS 1982 is now interpreted as a due diligence obligation that requires states to make maximum efforts to prevent marine pollution, including emissions released into the atmosphere. At the national level, Indonesia has made significant reforms through Presidential Regulation No. 110 of 2025 which allows for accelerated carbon trading without having to wait for the achievement of NDC targets. In addition, the enactment of Ministerial Regulation No. 1 of 2025 strengthens the technical governance of blue carbon as a mitigation instrument and economic asset. The study concludes that Indonesia has built a responsive legal foundation by integrating the Economic Value of Carbon into marine environmental protection. The implementation of MRV mechanisms and emissions certification demonstrates the state responsibility to fulfill international commitments. This legal harmonization is a prerequisite for slowing marine ecosystem degradation, safeguarding marine biodiversity, supporting food security for coastal communities, and advancing intergenerational environmental justice.  Nevertheless, consistency between economic acceleration and ecosystem integrity remains necessary to ensure sustainable marine conservation.

Abstract

Houseflies (Musca spp.) are common synanthropic insects in pig farming systems and are widely recognized for their potential role in the mechanical transmission of pathogens, particularly in tropical endemic settings. In Indonesia, pig farming is frequently conducted in close proximity to residential areas, where inadequate environmental management may increase risks to animal and public health. This study aimed to examine the presence and potential role of houseflies in pig farming systems and to assess their implications for health and environmental management in tropical Indonesia. A cross-sectional observational study was conducted in selected pig farming areas. Houseflies were collected using standardized trapping techniques from pig housing, waste accumulation sites, and surrounding environments. Microbiological analyses were performed to detect pathogenic bacteria associated with gastrointestinal and zoonotic diseases, while environmental management practices, including waste handling, sanitation, and biosecurity measures, were assessed through structured observations and interviews. The findings revealed high housefly density in areas characterized by poor waste management and suboptimal sanitation conditions. Pathogenic bacteria of public health significance were identified on the external surfaces of collected houseflies, indicating their potential role as mechanical vectors. Farms implementing better environmental management practices showed lower fly abundance and reduced levels of microbial contamination. These results underscore the importance of integrated health and environmental management in pig farming systems. Improving waste management, sanitation, and fly control measures is essential to reduce disease transmission risks and to support sustainable and health-oriented livestock production in tropical regions of Indonesia.

Abstract

Forest and land fires in Indonesia have repeatedly caused transboundary haze pollution that affects several Southeast Asian countries, particularly Malaysia, Singapore, and Brunei Darussalam. This situation raises an important question of state responsibility under international environmental law, especially through the principle of sic utere tuo ut alienum non laedas, which requires states to use their territory and natural resources in a manner that does not cause harm to other states. This principle is reflected in the 1972 Stockholm Declaration, the 1992 Rio Declaration, and the ASEAN Agreement on Transboundary Haze Pollution, which provides a regional framework for preventing and controlling transboundary haze. This study uses normative legal research with statutory and conceptual approaches to examine how the principle operates in the context of transboundary haze pollution in Southeast Asia. The analysis shows that the implementation of this principle requires states to exercise due diligence through prevention, monitoring, law enforcement, and regional cooperation. However, its effectiveness remains constrained by weak environmental enforcement, limited compliance mechanisms under ASEAN, and the persistence of the non-interference principle in regional governance. Strengthening the implementation of sic utere tuo ut alienum non laedas is therefore essential not only for state accountability, but also for protecting regional ecosystems, reducing greenhouse gas emissions from forest and land fires, supporting climate change mitigation, and advancing environmental justice and regional public health in Southeast Asia.

Abstract

The growing demand for environmentally sustainable chemicals in crude oil processing has intensified interest in green demulsifiers as alternatives to conventional petrochemical surfactants, which are often toxic, costly, and poorly biodegradable. This study investigates the synthesis, performance evaluation, and statistical validation of bio-based demulsifiers derived from oils of Khaya spp. (mahogany), Azadirachta indica (neem), and Crescentia cujete (calabash) for crude oil–water separation. The formulations were prepared through controlled thermal blending of lipophilic and hydrophilic components using camphor, paraffin oil, cassava starch, and liquid soap as intermediates and binders. Their efficiencies were evaluated using standardized bottle tests, with a commercial demulsifier from Nigerian National Petroleum Company Limited serving as the reference. The results showed demulsification efficiencies of 96.6%, 93.7%, and 92.6% for the mahogany-, neem-, and calabash-based formulations, respectively, compared with 97.0% for the commercial product. Statistical analysis confirmed significant differences among treatments (ANOVA: F = 69.83, p = 4.44 × 10⁻⁶), while Tukey’s post hoc test revealed no significant difference between the mahogany-based demulsifier and the commercial control (p > 0.05), indicating comparable performance. The mahogany formulation also exhibited the highest reproducibility (SD = 0.20), reflecting stable interfacial activity and consistent separation efficiency. Overall, these findings demonstrate that plant-derived oils are promising renewable feedstocks for eco-friendly demulsifiers, supporting cleaner petroleum-processing practices and circular bioeconomy principles by using biodegradable, sustainable industrial materials. The replacement of persistent petrochemical surfactants with biodegradable bio-based demulsifiers can significantly reduce marine pollution from oil-processing effluents while promoting sustainable resource utilization within a circular bioeconomy framework.

Abstract

This study developed an anomaly-based framework to map potential fishing zones (PFZs) in the Makassar Strait from satellite-derived sea surface temperature (SST) and chlorophyll-a (Chl-a) during 2022–2024. Daily GCOM-C/SGLI Level-3 Version 3 products were quality-masked, converted to physical units, aggregated to a 0.1° × 0.1° grid, and summarized as monthly composites. Monthly anomalies were then calculated relative to a month-specific three-year climatology. PFZs were defined as pixels simultaneously showing high Chl-a anomalies, represented by the 80th percentile of the spatial distribution of the temporal mean anomaly field, and relative cooling (SST anomaly ≤ 0). Monthly PFZ area ranged from 4,658 to 144,923 km², with a mean of 52,606 ± 33,834 km², whereas PFZ area fraction ranged from 0.012 to 0.352, with a mean of 0.130 ± 0.084. Seasonally, PFZs were most extensive during JJA (mean 66,973 km²; fraction 0.161) and least extensive during DJF (43,046 km²; fraction 0.112). Recurrent PFZ hotspots were concentrated in the central-southern Makassar Strait and along the eastern sector near the Sulawesi coast, where occurrence frequency reached about 58%. Valid-pixel diagnostics showed relatively stable AOI-level coverage (SST mean 0.534; Chl-a mean 0.548), indicating that the observed PFZ variability could not be explained by data gaps alone. These findings indicate that recurrent PFZs can be interpreted as pelagic ecosystem service hotspots that support ecosystem-based fisheries management, biodiversity conservation, and the sustainable use of marine resources, while aligning with SDG 14 (Life Below Water) and the post-2020 global biodiversity framework of the Convention on Biological Diversity.

Abstract

Environmental problems such as climate change, pollution, biodiversity loss, and environmental degradation have increased the importance of developing students’ environmental awareness through science education. One approach widely used to address this issue is Socio-Scientific Issues (SSI)-based learning, which integrates scientific concepts with real-world social and environmental problems. This study aimed to analyze research trends, characteristics, and the impacts of SSI-based learning on students’ environmental awareness through a Systematic Literature Review (SLR). Data were collected from Scopus-indexed articles published between 2016 and 2026 using the keywords “Socio-Scientific Issues” and “students’ environmental awareness.” Bibliometric analysis was conducted using Mendeley Desktop and VOSviewer to identify publication trends, research themes, and thematic relationships. The findings indicate a significant increase in SSI-related research over the last decade, particularly in the fields of science education, environmental education, and sustainability studies. Climate change, sustainable development, environmental protection, and scientific argumentation were identified as dominant research themes. The review also shows that SSI-based learning positively influences students’ environmental awareness, critical thinking, scientific literacy, argumentation skills, and pro-environmental behavior. Furthermore, the integration of SSI with Problem-Based Learning (PBL), Education for Sustainable Development (ESD), and digital learning tools strengthens students’ engagement with environmental issues. Overall, SSI is an effective pedagogical approach for promoting environmental awareness and sustainability-oriented education. Enhancing students’ environmental awareness through SSI-based learning is a critical strategy for developing sustainability-literate citizens who are capable of addressing global environmental challenges such as climate change, biodiversity loss, and pollution, in line with Sustainable Development Goal (SDG) 4.7 on Education for Sustainable Development.

Abstract

The Sustainable Development Goals (SDGs) provide a comprehensive global framework to address pressing social, economic, and environmental challenges. Despite the growing body of research, knowledge fragmentation and limited cross-disciplinary mapping hinder a holistic understanding of SDG research trends. This study aims to systematically map and analyze global SDG research developments from 2020 to 2026 using a bibliometric approach, with the 2025-2026 records treated as partial Scopus-indexed data rather than complete annual outputs. Data were retrieved from the Scopus database and processed with Publish or Perish, followed by scientific mapping in VOSviewer. The methodology included publication trend analysis, document-type distribution analysis, and keyword co-occurrence analysis to identify dominant research themes and emerging topics. A total of 186 publications were analyzed, revealing that comparable full-year research activity peaked in 2021-2022 and remained dominated by journal articles. Keyword analysis identified core clusters related to sustainable development, climate change, and food security, alongside emerging topics such as bioplastics, nanotechnology, low-carbon consumption, digital transformation, and sustainability education. These findings highlight both the evolution and diversification of SDG research, emphasizing the integration of technology, education, and practical applications. Understanding SDG research trends is essential for accelerating evidence-based environmental action, supporting climate mitigation strategies, and fostering interdisciplinary solutions to pressing ecological challenges such as biodiversity loss, pollution, and resource depletion. The study provides critical insights for researchers, educators, and policymakers to prioritize underexplored areas, foster cross-disciplinary collaborations, and guide evidence-based strategies for sustainable development.

Abstract

Smoking behavior among adolescents remains a serious public health issue in Indonesia. Social media has become a new platform for tobacco companies to indirectly promote their products through engaging content and influential public figures, potentially increasing adolescents' interest in trying cigarettes. This study aimed to analyze the relationship between exposure to cigarette advertisements on social media and adolescent smoking behavior in Banrimanurung Village, Jeneponto Regency. A quantitative research design with a cross-sectional approach was employed. The population consisted of 171 male adolescents, with 120 respondents selected through purposive sampling. Data were collected using a closed-ended questionnaire and analyzed using SPSS software with the Chi-Square test. The results showed a significant relationship between exposure to cigarette advertisements on social media and smoking behavior, with a p-value of <0.001 (<0.05). Exposure to cigarette advertisements on social media is therefore significantly associated with smoking behavior among adolescents in Banrimanurung Village. Increased awareness of smoking risks, stronger family and school supervision, and enhanced health promotion by community health centers are recommended. Moreover, reducing adolescent smoking through stricter digital advertising regulation not only protects individual health but also contributes to reducing environmental tobacco smoke (ETS) exposure in public spaces, decreasing cigarette butt waste — a major source of plastic and toxic pollution — and lowering the overall environmental burden of tobacco production and disposal, aligning with SDG 3 (Good Health and Well-being) and SDG 12 (Responsible Consumption and Production).

Abstract

Urban waste management in Indonesia is becoming increasingly challenging due to rapid population growth and changing consumption patterns that generate larger volumes of waste. One alternative approach that supports the principles of the circular economy is community-based waste management through waste banks. This study aims to analyze the business model of the Karya Mandiri New Waste Bank in Tebing Tinggi City using the Business Model Canvas (BMC) framework and to formulate development strategies for its sustainability. This study employs a qualitative descriptive approach with data collected through interviews, observations, and documentation. Findings indicate that the waste bank has implemented essential waste management activities, including collection, sorting, and environmental education programs. However, several obstacles still hinder its operational sustainability, such as limited community participation, inadequate resources, and unstable revenue streams. BMC analysis indicates that key elements, particularly the value proposition, channels, and revenue streams, have not been effectively optimized. Therefore, strategic improvements are needed through strengthened partnerships, increased community participation, diversification of revenue sources, and the utilization of digital technology. Optimizing the waste bank business model can help reduce landfill leakage, prevent marine plastic pollution, lower greenhouse gas emissions, and support Sustainable Development Goals (SDGs) 12 and 14 through sustainable waste management practices.

Abstract

The increasing concentration of atmospheric carbon dioxide (CO₂) has intensified the need for sustainable, energy-efficient, and scalable capture technologies. Membrane-based CO₂ capture has attracted considerable attention due to its compact configuration, continuous operation, and relatively low energy demand compared with conventional absorption processes. However, many polymeric membranes still face limitations related to the permeability–selectivity trade-off, poor humidity tolerance, weak mechanical stability, and limited CO₂ affinity. In this context, biopolymer-based functional membranes have emerged as promising platforms because of their renewable origin, processability, biodegradability, and tunable surface chemistry. This review discusses the fundamentals and recent progress of biopolymer-based membranes for CO₂ capture, focusing on the relationship between membrane composition, molecular interaction, and capture performance. Key mechanisms, including physisorption, chemisorption, carbamate and bicarbonate formation, and facilitated transport, are highlighted to explain CO₂ uptake and selective transport in functional membrane systems. Special attention is given to cellulose acetate, chitosan, poly(vinyl alcohol)-based matrices, nanocellulose-reinforced membranes, and amine-functionalized composite strategies. The roles of porous fillers, amine immobilization, interfacial compatibility, water stability, and regeneration behavior are critically discussed. Although biopolymer-based membranes offer strong potential for sustainable CO₂ capture, challenges remain in long-term cyclic stability, humid mixed-gas operation, filler dispersion, and scale-up fabrication. The development of sustainable, low-cost, and regenerable CO₂ capture membranes can contribute directly to mitigating climate change, reducing atmospheric greenhouse gas concentrations, supporting net-zero emission targets, and advancing SDG 13 (Climate Action) and SDG 7 (Affordable and Clean Energy).
