Abstract

This study aims to evaluate the surface carbon stock estimation model in Kendari City working area using Geographic Information Systems (GIS) and remote sensing approaches. Spatial analysis was carried out using Sentinel-2A satellite imagery with a resolution of 10 meters per pixel, employing the vegetation index method as the primary indicator for estimating carbon stocks. Field data were used as reference and validation for image interpretation results, which were processed using spatial statistical methods to produce an accurate and reliable surface carbon distribution model. The research findings indicate that the Kendari City area has a significantly varied distribution of carbon stocks, with values ranging from low to high at 203.669 tons of carbon per pixel. Areas with high vegetation cover, such as urban forests and green open spaces, exhibited higher carbon concentrations compared to settlement areas and densely urbanized regions. Model evaluation conducted through field validation methods revealed a high correlation between model predictions and actual field conditions. This research demonstrates that the integration of GIS and remote sensing is effective for rapidly and accurately mapping and evaluating potential surface carbon stocks. Spatial information about carbon reserves is crucial as a basis for formulating sustainable environmental management policies and climate change mitigation strategies in Kendari City. The results of this study recommend wider adoption of this method to support spatial data-based environmental management in other regions across Indonesia

Abstract

Thomas's langur (Presbytis thomasi) is an endemic primate of northern Sumatra whose conservation status is increasingly threatened by habitat degradation. This study aims to assess the spatial distribution and population structure of P. thomasi within the Sikundur Research Station of Gunung Leuser National Park. Data collection was conducted using the concentration count method, including recording of GPS coordinates, elevation, group composition, sex ratio, and age classification. A total of 24 individuals were identified across six social groups in four research blocks (A–D), with adults comprising 70.83% of the observed population. The estimated population density was 4.8 individuals/km². Chi-square analysis (χ² = 22.50) indicated a significantly clumped distribution pattern. This pattern likely reflects ecological factors such as food tree availability, habitat structure, and social behavior. The findings highlight the importance of habitat quality and spatial connectivity for the conservation of this vulnerable species.

Abstract

Kutai National Park serves as a vital habitat for diverse flora and fauna, yet the park faces challenges in achieving comprehensive and efficient mapping of its biodiversity. In alignment with the 2019–2029 Long-Term Management Plan, which prioritizes completing a robust mapping system, this study proposes the development of a Geographic Information System (GIS) based on a microservices architecture. The system aims to streamline data management and support area conservation efforts. Utilizing the Extreme Programming methodology, the project leverages React JS for the web interface, React Native for mobile applications, and MongoDB for database management. System testing incorporates Postman for microservices, Selenium for web applications, and Black-Box testing for mobile apps. Feasibility evaluations use Equivalence Partitioning and the Mean Opinion Score (MOS) method, reflecting high acceptance among staff (71% Strongly Agree, 29% Agree) and visitors (47.9% Strongly Agree, 43% Agree, 3.8% Neutral). The results demonstrate the system's potential to enhance biodiversity management while fostering stakeholder engagement in conservation initiatives

Abstract

Agriculture is the backbone of Indonesia's economy, absorbing labor and contributing significantly to national income. Optimization through technology and efficient resource management is essential to enhance farmer welfare and productivity. This study aims to analyze the financial feasibility of red chili farming in Ketol District, Central Aceh Regency, where farmers have shifted from sugarcane to chili due to economic, environmental, and social factors. The financial feasibility analysis includes: (1) income analysis, (2) R/C ratio, and (3) Break-Even Point (BEP). The results show that red chili productivity reaches 1,210 kg per planting season, with a selling price of Rp. 43,400/kg, generating an income of Rp. 39.8 million per season—higher than the national average. Financial analysis reveals an R/C ratio of 4.15, a production BEP of 291 kg (actual production: 1,210 kg), and a price BEP of Rp. 10,433/kg (selling price: Rp. 43,400/kg). These findings demonstrate the competitive advantage of red chili farming in the region, supported by high productivity and input efficiency. The study concludes that intensive technology-based red chili farming is economically viable and should be sustained through price stabilization strategies and market diversification

Abstract

Population growth is increasing beyond previous estimates. The world's energy needs are also extensive and continue to grow. This puts pressure on the energy available in nature in the form of biomass, and the decreasing fossil energy. So, alternative energy sources are needed that can be renewed in the form of Biofuel Sources. In addition, the development of biofuel energy source plants is a solution to restore environmental conditions. Based on this, it is necessary to identify the types of energy sources and the potential for developing biofuel energy source plants in the Bonehau Watershed ecosystem. The method used is non-experimental mapping based on Geographic Information Systems. The initial stage of introducing the identification of types of energy use by the community based on accessibility density classes. Furthermore, an analysis of the potential for developing biofuel plants, namely Nyamplung and Kemiri Sunan, was carried out using a land suitability approach. The Bonehau Watershed community generally uses LPG and firewood energy to meet household energy needs. Most people use more firewood energy than LPG because the watershed area has low accessibility, and the availability of firewood around the community's residence is limited. Analysis of Biofuel Plant Land Suitability in the form of Nyamplung Plants has the potential of 25% and Kemiri Sunan Plants 34% of the watershed area to be developed. The potential for developing these plants can handle 59% of the critical land for Nyamplung plants and 74% for Kemiri Sunan plants, from the total critical land area

Abstract

Ibu Kota Nusantara will be a significant smart sustainable forest city regarding climate change. Calculation of land-based carbon emission reduction performance in the IKN based on land cover maps through visual interpretation of medium-resolution satellite imagery sensing experiences uncertainty that follows a gradual process. In estimating emissions in this IKN, it is related to the uncertainty of land-based carbon emission activity data. This study aims to obtain the value of uncertainty in activity data from the dynamics of land cover changes in the IKN. The methodology used in this study is the interpretation of medium-resolution satellite imagery, and land cover changes using 5 (five) classes of change, namely deforestation, forest degradation, forest gain, stable forest, and stable non-forest, sampling design using stratified random sampling with the proportional allocation method. The results of the sample interpretation are then calculated for accuracy (user's accuracy, producer's accuracy, and overall accuracy) and uncertainty with a confusion matrix/error matrix. This study shows that changes in deforestation land cover produce high uncertainty values ​​(> 15%), this is because most of the samples for changes in deforestation land cover are in stable non-forest land cover changes, in actual the reference data from image data with high-resolution imagery does not match. While changes in stable forest and stable non-forest land cover throughout the year produce low uncertainty values ​​(≤15%), most of the samples for stable forest and stable non-forest land cover change conditions match in the diagonal column which shows that there is a match between the data class of land cover change classification results and reference data from high-resolution image data.

Abstract

Post-mining land rehabilitation is an important strategy to mitigate climate change and conserve tropical ecosystems. Surface mining activities in East Kalimantan have caused ecological degradation and the release of carbon stored in vegetation and soils. Revegetation has been widely practiced as the main approach to restore ecosystem functions, including initial carbon accumulation by understory plants. This study aims to estimate the carbon stock of the understory on post-mining land that has undergone revegetation for one year at the PT Insani Baraperkasa site in Loa Janan, East Kalimantan. The method used was destructive sampling of understory biomass from 10 plots measuring 5 m x 5 m, each with subplots measuring 0.5 m x 0.5 m. Biomass samples were dried and converted to carbon. The results showed an average carbon stock of 1.26 tons/ha. These results suggest that understorey vegetation plays an important role in early stage carbon recovery on post-mining land. Understory carbon monitoring can be an effective early indicator to measure the success of ecosystem restoration. Keywords: revegetation, understorey, post-mining, carbon
