Abstract

Sukosari Village faces significant economic disparities, characterized by a high poverty rate of 42.03% of a total of 1,230 families, low coverage of social assistance, and inequality in housing quality. Meanwhile, this village has great agrarian potential with 2,150 hectares of agricultural land and 1,191 farming families that have not been optimized. This study aims to analyze the economic gap and local agricultural potential of Sukosari Village, as well as formulate the concept of AgroTech Village Hub as an innovative conceptual framework solution based on digital technology to reduce inequality and sustainably strengthen food security. The research uses a conceptual-innovative approach supported by secondary data analysis from village monographs and relevant scientific literature reviews. Primary data was obtained through field observation to verify the actual condition of the village, while secondary data was sourced from the Sukosari Village Profile and Monograph in 2024. The results of the analysis show that Sukosari Village has great agrarian potential but has not been optimally utilized due to limited access to technology and information. In response, the concept of the AgroTech Village Hub was formulated, which includes five main components: Smart Farming Center, E-Commerce Production House, Digital Creative Studio & Co-Working Space, Virtual Reality AgroEduTour, and Renewable Energy & Sustainability Unit. This concept offers an integrated technology ecosystem that has the potential to increase agricultural productivity, expand access to the digital economy, and strengthen village food security.

Abstract

This study examines the spatial distribution of hypertension among elderly populations in Central Java and the contributing risk factors using 2023 Indonesia Health Survey data. The research employed descriptive analysis to illustrate hypertension prevalence, logistic regression to identify risk factors, and spatial mapping with the Hypertension Health Index (IKH) to explore geographic risk patterns. Results indicate regional variations with high-prevalence clusters in urban and coastal areas, influenced by biological, socio-economic, and behavioral factors, including gender, education, physical activity, and dietary habits. High IKH values were observed in areas with significant combined risk factors, while urban regions showed high prevalence but lower IKH due to mitigating factors. These findings highlight the importance of area-based health interventions, including nutrition education, early detection, and community-based physical activities for the elderly, alongside enhanced risk monitoring in urban settings

Abstract

International airport infrastructure development triggers complex spatial transformations with implications for the balance of regional ecosystems. This study analyzes land-cover change dynamics, surface temperature distribution, vegetation conditions, and microclimate risk zones in the Yogyakarta International Airport (YIA) area using Landsat 8 imagery processed on the Google Earth Engine platform. Methods include Random Forest classification for land cover mapping, Land Surface Temperature (LST) analysis, Normalized Difference Vegetation Index (NDVI) extraction, and Vegetation Stress Index (VSI) compilation as ecological pressure indicators. Results show a 27.2% expansion of forest cover and a 30.4% reduction in water bodies during 2015–2024, contrasting with conventional urban sprawl theory. Surface temperature increased across all land cover classes except built-up areas, which decreased by 2.85°C, with Urban Heat Island formation extending to a radius of 5–7 km. Findings introduce green intensification as a novel reforestation pathway driven by the internalization of mitigation obligations within infrastructure project design. This phenomenon challenges conventional theoretical assumptions and extends existing forest transition frameworks to tropical infrastructure contexts.

Abstract

Low-carbon development is a narrative of sustainable development in various countries, including Indonesia. This policy is part of Indonesia's global commitment to support climate change mitigation, achieve net-zero emissions, and promote sustainable, green economic development. However, the implementation of this policy raises crucial questions regarding the implementation and impact of low-carbon development policies in Indonesia. This study aims to analyze the gap between national-level low-carbon development policies and their implementation in the field, and to identify factors that hinder their effectiveness. The approach used is a qualitative study with library research and content analysis of 10 articles, official documents, and government reports from the 2020–2025 period. The data were analyzed using a thematic content analysis approach to identify patterns, implementation challenges, and barriers to low-carbon development policies. The results show that the implementation of PRK in Indonesia remains ineffective and tends to be partial, particularly in the energy, transportation, and environment sectors. The main obstacles include weak governance, limited funding, and low public awareness and participation. In addition, central-regional policy disparities and bureaucratic resistance also hinder the transition to a green economy. The success of the PRK requires institutional reform, strengthening regional capacity, and increasing public literacy and participation towards sustainable development.

Abstract

The massive growth of urban areas in the Depok subdistrict has triggered microenvironmental degradation, which has resulted in a decrease in the thermal comfort of the community. This study aims to identify the level of vegetation density of Public Green Open Space (GOS), map CO2 emission hotspots and thermal comfort (THI), and analyze the typology of the relationship between these variables. The method used is quantitative descriptive with the integration of remote sensing (NDVI Landsat 8) and spatial modeling. This study presents an original approach through a spatial typology analysis framework that synergizes THI, NDVI, and CO2 emission variables to analyze the complexity of microclimate phenomena in urban areas in depth. The findings show that the study area is dominated by the Comfortable-Low Emission typology (28.93%), especially in areas with high vegetation density. However, an urban heat island phenomenon was found in the critical zone of 0.56% which forms a thermal hotspot due to the effect of the urban canyon on the commercial area. Other findings show the typology of the THI and NDVI relationship dominated by the Comfortable-Low NDVI typology (24.74%), covering more than 52% of the area thanks to the support of 28 Public Green Open Space points and the campus forest on the west side. Conversely, critical areas with an Uncomfortable-Low NDVI typology (1%) are concentrated in commercial areas. Therefore, a government strategy is needed to prioritize protecting rice fields and adding shade vegetation in commercial areas.

Abstract

This study aims to understand the tidal flood storage pattern in Banjarmasin City through spatial and land cover modeling and to produce detailed and accurate maps of the area of ​​land cover inundated by tidal flooding and develop a spatial model to circle the impact of tidal flooding on various types of land cover. Modeling was carried out using the Ilwis Academic application analysis through the nearest neighbor (operational environment), considering air rise scenarios of 0.25 meters, 0.5 meters, and 1 meter, based on the average elevation of the Banjarmasin area. At an air rise of 0.25 meters, approximately 20.2% of agricultural land was inundated, increasing to 29.9% at an elevation of 0.5 meters. At an elevation of 1 meter, approximately 78% of the city area was inundated, with the agricultural sector being the most vulnerable to tidal flooding in all scenarios. These findings indicate the importance of effective mitigation strategies to reduce the negative impact of tidal flooding on the agricultural sector and daily activities in Banjarmasin City.

Abstract

Changes in human activity during the COVID-19 pandemic affected urban environmental conditions, particularly vegetation density and land surface temperature. This study analyzes vegetation and surface temperature changes in Yogyakarta City using Landsat-8 imagery from 2017 to 2022. A remote sensing approach was applied to derive vegetation indices and surface temperature and to compare pre-pandemic and pandemic periods. The results show an increase in minimum vegetation values from 0.027 to 0.048, while mean and maximum values decreased from 0.118 to 0.108 and from 0.309 to 0.276. Vegetation demonstrated a strong negative relationship with built-up areas, with correlation coefficients of −0.780 before the pandemic and −0.721 during the pandemic. Land surface temperature showed an overall cooling trend. These findings confirm that reduced human activity influenced urban thermal dynamics and vegetation patterns, emphasizing their importance for urban environmental resilience.

Abstract

The Great Acceleration since the mid-20th century, resulting from the dominance of anthropogenic activities on Earth, has had a significant impact on the environment, including geomorphological evolution. This paper aims to investigate the Anthropocene-geomorphological evolution in the outer Dieng Highlands, shaped by massive anthropogenic acceleration. This study employs a geomorphological approach. Data were collected through observation, remote sensing image interpretation, literature, and documents. The data were analyzed using descriptive geomorphological analysis, supported by geographic information systems and remote sensing. There are two significant findings in this study. First, anthropogenic activities during the Anthropocene have been highly dominant, marked by extensive land use for agriculture and settlements over the past five decades. Second, the Outer Dieng Highland is a volcanic complex; however, its current geomorphological evolution is primarily driven by the acceleration of exogenic processes induced by anthropogenic activities. Erosion and mass movements occur on a large scale, increasing drainage density, particularly in older volcanic units and less-resistant materials. In sum, this study offers new insights into the impact of anthropogenic activities on the acceleration of exogenic destruction across various structures within the volcanic complex.
