Abstract

The Indonesian government is firmly committed to achieving Net Zero Emission (NZE) by 2060. This involves transitioning the electricity sector by progressively replacing fossil fuels with renewable energy sources. The goal is to have a renewable energy mix of at least 23% by 2025 and at least 31% by 2050. This commitment applies to all provinces in Indonesia, including DKI Jakarta Province. This study aims to analyze the willingness and ability to pay DKI Jakarta Province residents for potential changes in energy prices resulting from an energy transition that increases the renewable energy mix. By 2023, the renewable energy mix in Indonesia reaches 13.3%. Coal is still the most widely used energy sources ini Indonesia, reaching 39,7%. This research employs quantitative methodology to ascertain the purchasing ability of the community for electrical energy through questionnaire distribution to PT PLN (Persero) customers. The respondents of this research are PT PLN (Persero) customers with household categories at all levels, which are R1, R2 and R3. The result showed that that a vast majority of respondents (97%) recognize coal as the primary energy source for electricity generation, with 96.3% acknowledging its negative environmental and health effects. Awareness of the government's energy transition policy is high at 97.6%, and 93.3% of respondents support the shift to renewable energy. However, the willingness to pay higher electricity tariffs declines across customer categories, with R1 at 54.13%, R2 at 47.83%, and R3 at 33.33%. The research results on respondents' ability to pay show that R1 category respondents represent 5% of the initial bill.  The R2 and R3 categories represent a maximum of 10% of the initial bill.

Abstract

The growth of Micro, Small and Medium Enterprises (MSMEs) has not been fully supported by the implementation of environmentally sustainable management strategies. This study aims to identify internal factors influencing environmentally friendly waste management among MSMEs and to measure their contribution to sustainable development in Aceh Tamiang Regency. The main focus is to assess how organizational structure, resource management, and environmental awareness within MSMEs affect sustainable empowerment, particularly in sectors that generate waste. The study population consists of 965 waste-producing MSMEs, with a sample of 300 respondents selected using purposive sampling to match the research criteria. Data was collected through structured questionnaires and analyzed using Structural Equation Modeling (SEM) with the assistance of AMOS software. SEM was chosen for its ability to test complex relationships among variables simultaneously and provide strong validity for the theoretical model. The findings show that internal company factors such as demographics, human resources, corporate culture, management practices, marketing, innovation capability, and employee awareness significantly influence MSME empowerment in adopting environmentally friendly practices. Furthermore, this empowerment contributes positively to sustainable development by reducing environmental impacts and improving economic efficiency. These findings are important for policymakers in Aceh Tamiang in designing sustainability-based strategies and policies for the development of local MSMEs.

Abstract

Society faces significant threats from external disruptions, particularly natural disasters, which impact both people and ecosystems. These disturbances require social-ecological systems to self-regulate and adapt to changing conditions. However, efforts to develop a comprehensive understanding of social-ecological resilience remain insufficient. To effectively grasp the dynamics and capacity of resilience, empirical studies are essential. Most research on this topic focuses on urban areas, often neglecting the unique conditions of rural communities. This study aims to assess rural resilience through the lens of social-ecological systems. Natural disasters progress through four key stages: pre-disaster preparedness, crisis management, post-disaster recovery, and learning for future resilience. Using qualitative methods, including interviews and focus group discussions, this research was conducted in Kutamendala Village, Brebes Regency. Findings reveal that resilience in disaster-prone villages can be strengthened through structured preparedness and continuous learning. The community demonstrated awareness of disaster risks and actively participated in risk reduction efforts rather than relying solely on external aid. Decentralized coordination allowed for effective disaster response, while post-disaster recovery efforts involved collaboration across sectors, improving infrastructure and essential services. Additionally, inclusive and sustainable learning initiatives were implemented, reinforcing long-term preparedness and strengthening the village’s ability to withstand future disasters.

Abstract

Research on river health assessment using biomonitoring with community empowerment through citizen science remains limited. This study aims to evaluate river health using biological indicators while fostering community involvement in data collection and analysis. The study focuses on the Gajahwong River in Yogyakarta City, an urban river undergoing changes due to urbanization. The methodology includes river health assessment based on macroinvertebrate biomonitoring, diversity index calculations, and a qualitative evaluation of the Citizen Index of Ecological Integrity (CIEI). Additionally, water quality data from the Environmental Agency (DLH) were analyzed as a comparison to community-collected data. Overall, the results indicate that the biological index falls under the moderately polluted category, consistent with abiotic parameter measurements (nitrate and phosphate), which also indicate pollution. Meanwhile, the CIEI reflects the community's perception of the ecological condition of the Gajahwong River, classifying it as moderate.

Abstract

Coasts or shorelines are sites of dynamic activity, and phenomena such as wave and tidal action, sediment supply rate, sea level changes, and the morphological characteristics of the area play a critical role in shaping coastal ecosystems. This study examines coastal changes along the Banyuasin Estuary in South Sumatra, Indonesia, over 30 years (1989–2019). We use remote sensing data, machine learning, and the DSAS tool to analyze historical changes (1989-2019). Landsat images obtained from the United States Geological Survey (USGS) via the Google Earth Engine API are analysed using ArcGIS and DSAS 6.0 software. The largest rate of change occurred at Anakan Island, with the most significant accretion rate being 118.98 m/year, causing a shoreline change of 2012.33 m over 30 years. The smallest shoreline changes were in the Telang and Payung Island areas, which are located in the Musi River Estuary. The magnitude of maximum shoreline change in both locations was 62.72 m and 92.34 m, respectively, with maximum rates of change ranging from 2.09 - 3.08 m/year. The results show that the general pattern of accretion-abrasion in the Banyuasin Estuary is divided into three stages: rapid accretion stage (1989-1994), accretion-erosion adjustment stage (1994-2009), and slow erosion stage (2009-2019).

Abstract

Perkotaan Muara Taweh merupakan pusat aktivitas dari Kabupaten Barito Utara. Sebagai Kawasan strategis di bidang ekonomi, Kementerian ATR BPN memberikan bantuan untuk penyusunan Rencana Detail Tata Ruang atau RDTR sebagai upaya penataan Kawasan yang lebih detail. Pada dokumen RDTR Perkotaan Muara Taweh 2022 – 2042, terdapat rencana Ruang Terbuka Hijau atau RTH baik berupa rimba kota, taman kota, taman kecamatan hingga jalur hijau. Rencana RTH ini diharapkan dapat menstabilkan iklim mikro perkotaan, menjadi resapan air hingga melindungi keanekaragaman hayati setempat. Dengan demikian, maka RTH harus ditempatkan pada lokasi yang sesuai dengan fungsinya. Hal ini diperlukan untuk menanggulangi beberapa permasalahan yang ada di Perkotaan Muara Taweh diantaranya tingginya polusi udara, kurangnya tutupan vegetasi dan kurangnya tutupan vegetasi pada RTH eksisting. Sehingga penelitian ini dilakukan dengan tujuan mengevaluasi perencanaan ruang terbuka hijau terhadap kondisi suhu permukaan bumi di Perkotaan Muara Taweh. Penelitian ini dilakukan dengan metode deduktif – kuantitatif – rasionalistik serta melalui alat overlay, maka didapatkan bahwa mayoritas RTH yang berupa rimba kota terletak pada kawasan sejuk. Hal ini menjadi poin yang tidak sesuai dengan fungsi RTH di bidang stabilitas iklim mikro, khususnya menurunkan suhu kawasan.  Dari hasil evaluasi diketahui RTH Taman Kota, Jalur Hijau dan Taman RW memiliki kesesuaian lokasi karena diletakan pada kawasan dengan suhu 30 – 34 oC. Dari ketiganya, Pemakaman memiliki tingkat penurunan tertinggi yaitu hingga 0,7 oC. Sementara itu, taman kota mampu menuruankan suhu hingga 0,28 oC. Sedangkan taman RW hanya dapat menurunkan suhu sekitar 0,21 oC.

Abstract

Meranti trees can capture and store carbon from the atmosphere, helping in the mitigation of greenhouse gas emissions. The Balikpapan City government has to realize and maximize its potential. This study intends to calculate biomass, carbon stock, and CO2 uptake in the Meranti ecotourism area in Balikpapan City to help the city's emission reduction target. The biomass of meranti plants was determined using an equation. The biomass of each upper meranti plant was determined using the formula ln(AGB) = -1.533 + 2.294 x ln(DBH) + 0.56 x ln(WD). The lower part uses the equation BGB = AGB x 0.2. The analysis of carbon stocks was conducted using formula C = 0.47x (AGB+BGB). Determine the amount of carbon in leaf waste by multiplying the leaf biomass by the percentage of carbon present. The study revealed that the Meranti ecotourism area in Balikpapan City has a biomass of 7,731 g and a carbon stock of 7,092 g. Both values can decrease CO2 emissions in the atmosphere by 10,711 grams of CO2 per hectare. The Meranti ecotourism region has the potential to expedite the Balikpapan City Government's efforts to reach the aim of lowering greenhouse gas emissions.

Abstract

Groundwater quality degradation in small volcanic islands presents complex challenges for freshwater availability, particularly where communities heavily rely on groundwater resources. A study of groundwater dynamics in dug wells on Ternate Island, Indonesia, examined the relationship between water volume changes and water quality parameters while evaluating seawater intrusion potential through hydrostatic balance analysis. Researchers measured physical parameters (temperature, surface pressure) and chemical parameters (salinity, dissolved oxygen, electrical conductivity, total dissolved solids) in three sample wells and one coastal point. The analysis incorporated calculations of water volume changes, flushing rates, and regression analysis between water volume changes and water quality parameters to assess the dynamics of groundwater quality fluctuations. Water level changes showed a 27-minute lag after tidal shifts, with well 1 showing dominant volume changes during ebb tide (65%), while wells 2 and 3 were dominant during flood tide. Well 2 showed higher susceptibility to quality changes due to its lower flushing rate (13.7%) compared to well 1 (56.6%). Statistical analysis revealed that water volume increases did not significantly influence water quality changes (p > 0.05). These findings enhance our understanding of groundwater dynamics in volcanic islands and suggest that factors beyond water volume changes should be considered when managing groundwater resources in these settings. The research provides valuable insights for developing effective water resource management strategies in similar geological contexts worldwide.

Abstract

Indonesia possesses the world’s largest mangrove forest area, which plays a vital role in global carbon regulation and coastal ecosystem services. However, these ecosystems are under increasing threat from anthropogenic pressures such as aquaculture expansion (especially shrimp farming), agricultural land conversion, and urban infrastructure development. These activities not only reduce forest cover but also compromise the ecological functions of mangroves, particularly their role as significant carbon sinks and oxygen producers. Given that mangroves have the highest carbon storage capacity per hectare compared to other forest types, their conservation is imperative in mitigating climate change. This study aims to assess the ecological and economic functions of mangrove forests in Kurau Sub-district, Tanah Laut Regency, South Kalimantan. Specifically, it quantifies aboveground biomass, carbon stocks, oxygen output, and the economic value of CO₂ sequestration. Data were collected through stratified random sampling based on vegetation density classes obtained from NDVI imagery, categorized into sparse, moderate, and dense classes. Field measurements focused on vegetation components from saplings to mature trees. Biomass was calculated using species-specific allometric equations, carbon stock was estimated by applying standard conversion factors, and oxygen production was derived using stoichiometric ratios. Economic valuation was conducted using a market-based approach, referencing global carbon pricing standards. The findings reveal that dense vegetation areas provide the greatest ecological benefit, with biomass of 54.72 tons/ha, carbon stock of 25.72 tons/ha, and oxygen production of 68.66 tons/ha. These ecological values translate into an estimated economic benefit of IDR 1.57 billion per year, indicating potential for integrating mangrove conservation with community-based development programs.
