Briefed on the development and progress of CCUS projects in China, USA, Western Europe, Russia, Norway, India, and Indonesia: a journal review Rimbono, Rudianto Koestoer, Raldi H. CCUS climate change global warming net zero emissions policies The global commitment to manage climate change issues is getting stronger and stronger. Therefore this review is carried out with the objective to obtain recent progress of efforts on emission control and handling through CCUS by various countries around the world. This review is carried out to highlight the development of carbon capture utilization and/or storage (CCUS) in China, the USA, and India, as these countries are known to be the most energy consumption countries. Its campaign to reduce emissions will contribute significantly to the effort of managing the global warming issue. The method used in this study is a literature review on the policies, studies, and projects mainly in China, and several other countries for comparison. The review found that although China is relatively late in doing such activities on climate change, but the progress is significantly faster than the others. The numbers of studies and patents are much higher than other countries, and the central and local governments issued a number of policies to help encourages the industries. The USA is known as one of the leading countries implementing CCS/CCUS and still creating incentive policies. European, Russian, and Indian countries pay serious attention to this effort and implement it while Indonesia as a non-industrial country is catching up.. From this literature research, it can be concluded that the technology for implementing CCUS is still at a high cost so policy and government funding support is needed as well as non-traditional sources of capital source such as green funding, carbon trading, etc. Institute for Advanced Science, Social, and Sustainable Future 2023-07-31 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article application/pdf https://journal-iasssf.com/index.php/AES/article/view/42 10.61511/aes.v1i1.2023.42 Applied Environmental Science; Vol. 1 No. 1: (July) 2023 3025-0412 10.61511/aes.v1i1.2023 eng https://journal-iasssf.com/index.php/AES/article/view/42/51 Copyright (c) 2023 Applied Environmental Science

The electric vehicle transition in Russia and Indonesia Shahboz, Ashurzoda Koestoer, Raldi Hendrotoro Seputro electric vehicles (EVs) green technology Indonesia Russia transition Due to worries about global warming and its effects on the environment, economy, and society, a lot of emphasis has been paid to the switch to electric vehicles (EVs). This essay focuses on the switch to electric vehicles in Indonesia and Russia. Green technology, such as EVs, have been introduced in Indonesia in order to lower carbon dioxide (CO2) emissions and enhance air quality. The study emphasizes the advantages of EVs, including their simplicity and improved comfort when compared to conventional vehicles, as well as their free highway use, parking, and tax incentives. The restricted affordability, ambiguous national policies, and inadequate public infrastructure provide difficulties for Indonesia. However, relative to its enormous auto fleet, Russia has lagged behind in the development of EVs, with just a tiny number of registered electric vehicles. However, the Russian government has approved a plan to increase the infrastructure and production of electric road transport. The strengths, weaknesses, and transitional strategies for EVs are assessed using a case study approach and comparative analysis. In order to encourage the use of EVs, it is stressed the significant of incentive programs and supportive policies, such as tax breaks and regional manufacture.  The study comes to the conclusion that although both nations have made progress in the transition to electric vehicles, more has to be done in terms of policy creation, infrastructure development, and technological improvements in order to hasten the adoption of EVs in Russia and Indonesia.

Strategi masyarakat pesisir Margolinduk dalam penanganan banjir rob serta implikasi terhadap sikap peduli lingkungan Bariroh, Ghurrotul Surtikanti, Hertien Koosbandiah countermeasures environmental concern tidal flood Margolinduk Village is one of the coastal villages on the north coast of Central Java which is worst affected by the tidal floods in Demak Regency. The various losses felt by the people of Margolinduk Village due to tidal floods have not reduced the resilience of the people to stay put. So that various handling efforts are deployed by the community in order to survive. However, so far there has been no research that examines the strategies of the Margolinduk Village community in dealing with tidal floods. Therefore, this research aims to find out the strategies used by the Margolinduk Village community in dealing with tidal floods and the implications for attitudes toward caring for the environment. Community efforts to deal with tidal floods should lead to concern for the environment. However, this attitude of caring for the environment must be proven by measuring indicators of caring for the environment. The method in this research is descriptive qualitative. Data collection was carried out through questionnaires, interviews, and observations. The number of samples used in this research was 30 people taken by purposive sampling. The Margolinduk Village community's strategy for dealing with tidal floods is by raising house buildings and looking for other alternative jobs. Even though the education level of the people of Margolinduk Village is still relatively low, the attitude of caring for the environment of the people of Margolinduk Village is in the very good category. Thus, what is found in this research is that attitudes that care about the environment do not always arise because of the knowledge taught at school. Direct experiences or individual impacts due to tidal floods have deep emotional and practical dimensions, thus playing a crucial role in shaping changes in attitudes and behavior towards greater environmental awareness.

Optimization of palm oil biodiesel production: Environmental impact analysis and POME waste utilization Paminto, Ari Kabul Karuniasa, Mahawan Frimawaty, Evi biodiesel life cycle assessment CO2 (eq) emissions acidification eutrophication Background: Indonesia is still an energy importer, especially in the form of crude oil and fuel products to meet the needs of its industrial sector. The reduced production of fossil energy, especially oil, as well as the global commitment to reducing greenhouse gas emissions, has prompted the Indonesian government to continue to support the role of new and renewable energy. The production of palm oil-based biodiesel is faced with a number of environmental problems, which may occur from the release of emissions during the production of FFB (Fresh Fruit Bunches), CPO (Crude Palm Oil), and biodiesel. Therefore, the purpose of this research is to compile an LCI (Life Cycle Inventory) covering the production of FFB, CPO, and biodiesel; analyze the environmental impact of the CPO bodysel production process which includes CO2 (eq) emissions, acidification and eutrophication; and develop a life cycle concept for biodiesel production from palm oil as a renewable energy. Methods: The method used in this study is a combination of quantitative LCA (Life Cycle Assessment) and AHP (Analytical Hierarchy Process) and qualitative. Findings: The results of this study are LCI in 1 ton of biodiesel consisting of NPK fertilizer of 141.1 Kg; herbicide (0.25 Kg); water (1578 m3), diesel oil (25 Kg); fresh fruit bunches of 5.67 tons; electricity of 33.8 kWh, POME (Palm Oil Mill Effluent) (3,47 m3), CPO needed for biodiesel conversion of 1.17 tons; methanol (0.41 tons), and 0.01 tons of Sodium Hydroxide. The total CO2 emission (eq) of biodiesel production from palm oil is 1489 Kg CO2 (eq), eutrophication is 1.12 Kg PO43- (eq) and acidification is 3.06 Kg SO2 (eq). With the largest contribution of CO2 (eq) emissions in CPO production and the contribution of eutrophication and acidification in oil palm plantations or FFB production (Fresh Fruit Bunches). Environmental hotspot of LCA, CO2 (eq) emissions from palm oil biodiesel production show that 53% mainly comes from POME (Palm Oil Mill Effluent) waste, other contributors are NPK fertilizers (23%), methanol (18%), and diesel oil (7%). Hotspot eutrophication showed that 61% mainly came from NPK fertilizer, methanol (20%), diesel oil (11%), and POME waste (8%). Hotspot acidification showed that 48% mainly came from NPK fertilizers, methanol (28%), POME waste (13%), and diesel oil (11%). Conclusion: The concept of a biodiesel production life cycle can be applied with the best alternative utilization of POME waste with a priority weighting of 0.357 and a CO2(eq) emission criterion of 0.494. From the optimization of the life cycle of biodiesel production with the use of POME, the potential for emission reduction is 667.2 Kg CO2 (eq). Novelty/Originality of this Study: This study's novel application of LCA evaluates the environmental impacts of biodiesel production from palm oil in Indonesia, identifying critical hotspots in CO2 emissions, eutrophication, and acidification. Additionally, it proposes an innovative optimization approach by utilizing POME to significantly reduce greenhouse gas emissions, highlighting a viable path for enhancing the sustainability of biodiesel production.

Application of spectral indices and deep learning (convolutional neural network model) on land cover change analysis Hikmah, Nur ‘Izzatul Manurung, Parluhutan land cover change spectral indices convolutional neural network (CNN) Semarang City urbanization remote sensing coastal management Background: Understanding land cover change is crucial for sustainable urban development, particularly in rapidly growing coastal cities such as Semarang City, Central Java, Indonesia. Methods: This study investigates spatial and temporal patterns of land cover change from 2000 to 2025 by integrating multi-temporal Landsat satellite imagery, key spectral indices—namely the normalized difference vegetation index, normalized difference water index, and normalized difference built-up index—and a deep learning approach based on convolutional neural networks. Annual Landsat images were preprocessed for atmospheric correction, cloud masking, and spatial subsetting using Google Earth Engine. Adaptive thresholding was then applied to each spectral index to delineate vegetation, water bodies, and built-up areas. Findings: Quantitative analysis revealed a significant decline in vegetation cover, with the normalized difference vegetation index dropping from 53.66% (397.59 km²) in 2000 to 46.83% (346.98 km²) in 2025, driven by urban expansion and landscape conversion, especially in coastal and lowland areas. Normalized difference water index analysis indicated a reduction and fragmentation of water bodies after 2015, linked to reclamation, sedimentation, and urban encroachment. Conversely, built-up areas expanded steadily, confirming accelerated urbanization. Scatter plot and regression analyses showed strong inverse relationships among vegetation, water, and built-up land, emphasizing ecological trade-offs and the loss of green-blue infrastructure. Conclusion: To enhance classification accuracy, a convolutional neural network was trained and validated on image patches, achieving a validation accuracy of 60%—outperforming conventional threshold-based methods by better capturing complex spatial patterns.

Dynamics of surface water resource management towards fulfilling agricultural irrigation Sani, Inuwa Sani Taqyuddin Naabba, Aliyu Hassan surface water NDWI remote sensing agricultural irrigation Kano State Background: The dynamics of surface water resources and their influence on agriculture irrigation in Kano State, Nigeria, 2015-2025, are displayed in this research. This study aims to examine the influence of surface water availability changes on irrigation potential in semi-arid catchment. With looming uncertainty concerning water scarcity, particularly in Northern Nigeria, spatial-temporal dynamics of the surface water are critical to sustainable agriculture planning. Current studies have used satellite-based indices to monitor changes in water bodies and emphasized that such changes must be associated with climatic factors and land use patterns for irrigation development decision-making. Methods: Remote sensing data, including Normalized Difference Water Index (NDWI) from Landsat and Sentinel data, and rainfall data from the CHIRPS dataset, were used for the study. Spatiotemporal modeling methodology was used that included NDWI trend analysis, NDWI–rainfall relation, overlay with cover of cultivated land, and zonal statistics at the Local Government Area (LGA) level. Findings: Findings show that there is general surface wetness expansion in the southern and central regions of Kano State owing to enhanced irrigation activities, heightened water holding capacity, and possible aquifer recharge. Conclusion: The study concludes that water resource management in Kano must be specially crafted to overcome localized climatic stress conditions and spatial hydrological imbalance to facilitate sustainable irrigation under semi-arid conditions.Ground-truth verification is however absent, which limits the accuracy of surface wetness estimates, and future incorporation of field-based hydrological observations is recommended. The findings present actionable advice for policymakers on improving irrigation strategy formulation and adaptive water management in semi-arid climates. Novelty/Originality of this article: This research integrates satellite-based NDWI for the first time with rain anomaly and land use overlays to determine water body dynamics and their agricultural implications at sub-regional scales.

Circular economy opportunities for inorganic waste management: An applied analysis based on recycling center data Ariyanti, Agni Lili Fakhirah, Aisyah Alfareza, Akbar Putra Surdianto, Arif Nur Solikhah, Feivie Wihdya Suleman, Yulia Azizah Laksono, Gangsar Edi Purwono waste bank waste production inorganic waste circular economy community participation Background: Waste is no longer regarded solely as refuse but also as a potential resource in the circular economy, particularly through recycling center (hereinafter referred to as pusat daur ulang-PDU) mechanisms. This study aims to analyze the circular economic potential of inorganic solid waste based on actual selling price data from PDUs in Purbalingga, Central Java, Indonesia. Previous studies have highlighted the importance of waste separation and local PDUs in promoting community-based waste management, yet few have quantified the circular economic value of specific inorganic waste types. Methods: This research employs a descriptive quantitative approach using secondary data collected from government institutions and local PDUs. Analytical methods include compositional waste analysis and basic statistical comparisons (T-Test) across years and waste types (polyethylene terephthalate-PET, scrap papers, and cans). Findings: PET accounted for an average of 18.53% of total waste between 2021 and 2024, far higher than paper (8.96%) and cans (0.66%). Statistical analysis confirmed significant differences between PET and the other two types (p < 0.05, Cohen’s d > 3). Scenario modeling showed that if 14.8% of the population participated by contributing 3 kg of PET per household, approximately 460 tons/day could be recovered, generating meaningful household income and reducing landfill burden. Conclusion: The study concludes that supporting PDUs and encouraging less than 20% household participation in PET separation could substantially reduce waste volumes while strengthening household income streams. Novelty/Originality of this article: The integration of compositional waste data and local price structures provides a data-driven valuation of inorganic household waste, offering practical guidance for policy and local planning in sustainable circular economy strategies.
