Spatial Assessment of Carbon Emissions Caused by Industrial Activities in Batang Anai, West Sumatra
This study aims to analyze: (1) the spatial distribution of carbon emissions in Batang Anai District, Padang Pariaman Regency, and (2) the impacts of carbon emissions on environmental quality and community settlements. The primary focus is to map emission patterns while also assessing their socio-economic and public health implications. A descriptive quantitative method with a spatial analysis approach was applied, utilizing Geographic Information System (GIS) techniques supported by ArcGIS software. Data collection included field surveys, interpretation of land cover imagery from 2015 and 2025, estimation of potential carbon stocks, and questionnaire distribution to residents within a 2-km radius of industrial areas across three villages (Kasang, Katapiang, and Sungai Buluh). Analytical procedures involved overlaying carbon emission and land cover maps, calculating carbon concentrations, and processing perception data using a Likert scale to assess environmental, health, and socio-economic impacts. The results reveal: (1) the spatial distribution of carbon emissions is categorized into three levels—low, medium, and high; and (2) communities report deteriorating air quality, increased dust and air temperatures, respiratory illnesses, and reduced living comfort. These findings highlight the urgent need for industrial zoning-based carbon emission control and the establishment of vegetative buffers around industrial zones to enhance environmental sustainability and community well-being.

Geospatial Perspective in the Distribution and Zoning Model of Senior High Schools in Bandar Lampung City
The school zoning system aims to improve equitable access to education; however, its effectiveness largely depends on the spatial distribution and availability of educational facilities. This study analyzes the spatial distribution and zoning evaluation of 17 public senior high schools in Bandar Lampung City based on the 2024 New Student Admission (PPDB) Technical Guidelines. A quantitative approach was employed using Geographic Information Systems (GIS), including geoprocessing and buffering techniques to map service zones. Data were obtained through documentation and field observations, then analyzed using: (1) Nearest Neighbour Analysis (NNA) to identify distribution patterns, and (2) GIS-based buffering to delineate service areas. The results show: (1) the distribution pattern of public senior high schools is random (NNA value = 1 km), indicating uneven spatial distribution; and (2) buffering analysis within 0–3000 meters identifies both served and underserved areas, particularly in suburban regions such as Panjang, Telukbetung Barat, and Sukabumi. The findings conclude that the 3 km zoning radius is not yet optimal in ensuring equitable access across all areas. Policy recommendations include: (1) establishing new school units in underserved regions, (2) adjusting zoning policies based on spatial analysis, and (3) optimizing school transportation. These results emphasize the need to integrate GIS into spatially based educational planning.

The Dynamics of Public Green Open Space Availability in Ciputat District, South Tangerang City, 2011–2025
South Tangerang City, particularly Ciputat District, is experiencing rapid development, which has significant implications for the conversion and reduction of public green open spaces (GOS). In evaluating the availability of GOS, it is essential to consider both the extent of existing green spaces and their alignment with the Regional Spatial Plan. This study aims to analyze changes in the availability of public green open space in Ciputat District from 2011 to 2025 and assess its conformity with the Regional Spatial Plan. A quantitative descriptive approach was employed, with data processed using ArcGIS through overlay and digitization methods. The results indicate that public green open space in Ciputat District increased slightly from 16,268 ha in 2011 to 16,848 ha in 2025. However, this represents only 3.8% of the district’s total area, far below the 20% requirement for public green open space stipulated in the Regional Spatial Plan. These findings highlight a significant shortfall in meeting spatial planning standards, underscoring the urgent need for policy interventions to preserve and expand green open spaces as essential components of sustainable urban development.

The Influence Between Place of Residence and Disaster Adaptation Capacity Among Generation Z
Lampung Province is categorized as a highly vulnerable area due to its proximity to the Indian Ocean, the Sunda Strait, and the volcanic activity of Anak Krakatau. This geographical setting poses significant adaptation challenges, particularly for Generation Z, a strategic age group in disaster mitigation. This study aims to examine the relationship between place of residence and tsunami disaster adaptation capacity among Generation Z, with a specific focus on geographical proximity to the Megathrust and Krakatau Volcano. A quantitative approach was employed through an online survey distributed to 261 students of the University of Lampung. Data were analyzed using descriptive non-inferential statistics and multiple linear regression. The results indicate variations in disaster literacy levels across regions, with the highest scores reported by respondents from Bekasi (100) and Prabumulih (98), while the lowest scores were observed in Musi Banyuasin (66.5) and Medan (69.67). However, regression analysis revealed that geographical distance from either the Megathrust or Krakatau had no significant effect on tsunami literacy (Sig. > 0.05). These findings highlight that distance is not the primary determinant; rather, disaster experience, access to information, education, and local policy play a more substantial role in shaping the preparedness of Generation Z. The study recommends integrating disaster literacy into higher education curricula and strengthening evacuation simulations as adaptive strategies

Accessibility Of Tourist Objects In Vietnam Village In Sumber Agung Village, Kemiling District, Bandar Lampung City
Kampoeng Vietnam, located in Sumber Agung, Kemiling District, Bandar Lampung City, is a natural tourist destination offering scenic landscapes but constrained by limited accessibility. This study aims to assess accessibility using six variables: alternative routes, travel distance, travel time, road conditions, transportation modes, and travel costs. A quantitative descriptive method was employed, with data collected through observation, documentation, and structured interviews. Spatial scoring analysis was applied to classify accessibility into three levels: high (>19), moderate (14–19), and low (8–13). The findings reveal that the site has three primary access routes, with 75% of respondents rating them positively. Travel distances were generally under 35 km (93%), and 75% of visitors reported travel times of less than one hour. Road surfaces were predominantly asphalt or damaged concrete (72%), and uneven terrain was noted by all respondents. All visitors relied on private land transportation, and 59% reported spending less than IDR 25,000 per visit. The overall accessibility score was 18, indicating a moderate level. The study concludes that improving road quality, providing public transportation options, and enhancing cost-efficiency are necessary to increase accessibility and visitor comfort.

Societal Adaptation to Coastal Tidal Flooding in Sayung Subdistrict, Demak Regency
Tidal flooding (rob) along Pantura Road in Sayung District, Demak Regency has compelled local communities to adopt diverse adaptation strategies for survival. Using a descriptive qualitative approach with a case study design, this research explored coastal community adaptation strategies through observation, in-depth interviews, and document analysis. The findings reveal that adaptation varies according to economic capacity. Physical adaptations include raising house foundations, constructing multi-story buildings, and adopting stilt house designs. Socioeconomic adaptations involve collective action to remove road barriers, repurposing newly inundated pond areas, and diversifying livelihoods. Public facility adaptations are evident in the elevation of cemetery grounds and the modification of school infrastructure. Government interventions support these efforts through the development of pumping systems, construction of water barriers, and dredging of sedimentation channels. While tidal flooding reaching up to 40 cm disrupts daily community activities, it also creates new economic opportunities, particularly in fish cultivation. Overall, the study demonstrates that community adaptation is both dynamic and rooted in local wisdom, enabling resilience in the face of climate change impacts. These insights provide valuable contributions to understanding coastal community resilience and serve as references for adaptive management policies in similarly vulnerable coastal regions experiencing sea-level rise and recurrent tidal flooding.

Spatial Variability of Land Use Changes Due to JJLS (Southern Cross Road Network) Development in Kulon Progo Regency in 2016, 2020, and 2024
The construction of the JJLS (Southern Cross Road Network) project in Kulon Progo Regency passes through Kapanewon Galur, Panjatan, Wates, and Temon to connect the Provinces of DIY and Central Java. The development of JJLS infrastructure can lead to the development of residential land and other functional buildings in the surrounding areas (Hendry, 2021). This study attempts to determine changes in land use variability due to the construction of JJLS in Kulon Progo Regency. Based on this information, changes in land use that occur intensively in certain areas can be monitored and detected early, so that appropriate policies can be formulated to prevent uncontrolled changes in land use. The research method used in this study is the interpretation of digital sentinel 2 imagery, which is then overlayed with a land use map to determine land changes that occurred in 2016, 2020 and 2024. Statistical analysis was carried out to determine the effect of JJLS development on land use changes in Kulon Progo Regency, especially in the sub-districts through which JJLS passes. The results of the study showed that there were significant changes in land use in the range of 2016, 2020 and 2024. Based on the results of the RCI calculation in 2016 to 2020, the lowest RCI value was 0,2917 and the highest value was 3,156. While the RCI value for 2020 to 2024 had the lowest value of 0.3862 and the highest was 2,1791. Based on the RCI value, it is divided into 3 classes, low, medium, and high, in order to represent the intensity of change in each village. Based on the results of statistical calculations, it can be concluded that there is a strong influence between the JJLS variable and the growth of built-up land in the research area.

The Relationship Between Subdistrict Spatial Development, Agricultural Land Conversion Rate, and Business Investment Growth in Pacitan Regency
The regional development of Pacitan Regency is significantly influenced by land-use conversion dynamics and business investment activities based on the KKPR (Conformity of Spatial Utilization Activities), particularly following the construction of strategic infrastructure such as the South Coast Route (JLS). This study aims to analyze the relationship between regional development, the rate of agricultural land conversion, and the rate of KKPR-based investment across 12 subdistricts using a quantitative approach. Data were collected from infrastructure availability, land conversion requests, and KKPR permits, then analyzed using the scalogram method, centrality index, and multiple linear regression via SPSS. The results indicate that Pacitan Subdistrict functions as the primary service center with the highest score (455.59), also recording the highest land conversion rate. The correlation between regional development and land conversion is very strong, whereas the relationship with investment rate is statistically insignificant. Regression analysis shows land-use conversion as the dominant influencing factor (R² = 0.967). This study highlights the urgency of land conversion control and spatially equitable investment strategies to support sustainable and balanced regional development

The Meaning of Place in Historic Building (Case Study: Three Urban Heritage Tourism Destinations at Kesawan Medan)
Based on the Regional Spatial Planning of Medan City for the years 2011-2031, several Cultural Heritage Areas have been established that include various historical buildings, one of which is located in the Old City area of Kesawan. The presence of historical buildings such as the Lonsum Building, Tjong A Fie, and Pos Bloc coexists with the rapid business and culinary activities on Ahmad Yani Street and Balai Kota Street. There are indications that a shift in visitation orientation has occurred where the meaning of tourism is stronger compared to a comprehensive exploration of history. The aim of this research is to analyze the meaning of place at three historical buildings and its implications for regional development. This research is qualitative with a geographical approach. In-depth interviews were conducted with 36 informants selected through purposive sampling. The research results show that the meaning of place in the three historical buildings is more dominated functionally, socially, and emotionally than by regional romanticism. The shift in the meaning of historical buildings is a consequence of the massive development of alternative tourism in urban areas. Therefore, it is necessary to reorganize the cultural heritage area involving elements of the community, government, and private sector, with the hope that the authentic value of historical buildings is not entirely eroded by the modernity of urban development.

Spatial Distribution of Macrozoobenthos in Relation toOceanographic Parameters in the Marine Waters Surrounding TundaIsland
This study explores the spatial distribution of macrozoobenthos in relation to oceanographic parameters in the waters surrounding Pulau Tunda, Banten. A combination of remote sensing data namely sea surface temperature (SST), salinity, chlorophyll-a concentration, and bathymetry was utilized alongside direct field sampling at three designated stations. Oceanographic data were extracted from Landsat 8 imagery and GEBCO bathymetric sources, processed using ArcGIS Pro and Global Mapper. The Shannon-Wiener and Simpson indices were applied to assess biodiversity and species dominance. Results reveal that areas exhibiting SST between 28–31°C, moderate salinity levels (31–32 ppt), and high chlorophyll-a concentrations tend to support moderately diverse and stable benthic communities, predominantly composed of gastropods. The findings highlight the utility of remote sensing for habitat prediction and emphasize the ecological potential of Pulau Tunda's coastal waters.

Spatial Distribution Analysis of Land Use, Land Surface Temperature, and Temperature-Humidity Index in Bogor City in 2004, 2014, and 2024
Rapid urbanization in Bogor City in 2004, 2014, and 2024 caused significant changes in land use, marked by an increase in built-up areas and a decrease in vegetation cover. These changes triggered an increase in Land Surface Temperature (LST) and Temperature Humidity Index (THI), which had an impact on heat stress, health disorders, and a decline in quality of life. This study analyzes the relationship between land use changes and LST and THI and develops an interactive web application for visualization. Land classification was performed using the Random Forest algorithm, LST was calculated from Landsat thermal bands (TM 2004, OLI/TIRS 2014 & 2024), and THI was based on Air Temperature (T(a) )and Relative Humidity (RH). The results show that built-up land increased by 2,074 ha (from 4,371 ha to 6,445 ha), in line with an increase in average LST from 26.16°C to 27.13°C and THI from 24.30 to 24.90. In conclusion, the increase in built-up area contributed significantly to the rise in LST and THI, emphasizing the importance of sustainable spatial planning, such as optimizing green open spaces to maintain thermal comfort and quality of life.Keywords:

The largest flood events on the Gajah Wong River occurred in early 2016 and mid-2016, this disaster caused the Gajah Wong River embankment to collapse, as a result the floods continued to overflow and enter residents' settlements as high as 2 meters. This is because the capacity of the river exceeds the peak discharge. This study aims to calculate the peak discharge using the rational method by utilizing data on daily maximum rainfall in the range from 2001 to 2021. The results of the study show that there was an increase in the inundation area for each flood return period. The peak flood discharge in the Gajah Wong River Segment using the rational method respectively for return floods of 2, 5, 10, 25 and 50 years is 61.41 m<sup style="color: #333333; font-family: 'Open Sans', sans-serif;

<span style="color: #333333; font-family: 'Open Sans', sans-serif; font-size: 12.6px; font-style: normal; font-variant-ligatures: normal; font-variant-caps: normal; font-weight: 400; letter-spacing: normal; orphans: 2; text-align: left; text-indent: 0px; text-transform: none; widows: 2; word-spacing: 0px; -webkit-text-stroke-width: 0px; white-space: normal; background-color: #ffffff; text-decoration-thickness: initial; text-decoration-style: initial; text-decoration-color: initial; display: inline !important; float: none;">This study compares of two types of multispectral cameras, DJI Mavic 3M and MAPIR RGN, in assessing sugarcane health through reflectance analysis and vegetation indices. The research was conducted in a sugarcane plantation in Sidoarjo, East Java, using multispectral data captured by drones. The analysis evaluated the relationship between reflectance values, vegetation indices, and chlorophyll content in sugarcane. Results indicate that the MAPIR RGN camera outperformed the DJI Mavic 3M in measuring chlorophyll content. The Near Infrared (NIR) channel of MAPIR RGN showed the highest correlation with chlorophyll (r = 0.2166). Additionally, the Ratio Vegetation Index (RVI) from MAPIR RGN had the strongest correlation (r = 0.2716) among all vegetation indices. Conversely, the DJI Mavic 3M camera demonstrated weaker correlations across all reflectance channels and vegetation indices. These differences may stem from sensor sensitivity and the quality of data produced by each camera. Based on these findings, the MAPIR RGN camera is recommended for precision agriculture applications in sugarcane plantations, as it provides more accurate spectral data reflecting vegetation health. This study underscores the relevance of drone technology in enhancing the efficiency of sugarcane plantation management.

Management Evaluation of the Parangtritis Sand Dunes Tourist Attraction Using the DPSIR Approach
The Parangtritis Sand Dunes, an important geoheritage area, serves as a natural shield against tsunamis, a rainwater catchment area, and a unique habitat for biodiversity. However, uncontrolled land use change threatens its sustainability. This study uses the DPSIR framework to analyze land use dynamics and propose sustainable management strategies. The results show that inappropriate afforestation policies, infrastructure development, and tourism activities disrupt the aeolin process, thereby reducing the area of sand dunes in the core zone. Some of these things degrade the function of the sand dune ecosystem. Recommendations include enforcing zoning regulations, rerouting tourism jeeps, and educating the community.

Analysis of Wind Speed and Direction Variability for a Preliminary Study of Wind Energy in Coastal Areas
Wind variability in coastal areas is a key factor influencing regional climate patterns, ecosystem stability, and maritime activities. This study aims to analyze the variability of wind speed and direction in the coastal region of Paloh District, West Kalimantan, using the Weibull statistical distribution and Windrose diagrams. Wind data were obtained from the BMKG Meteorological Station in Paloh over a 15-year period (2009–2023). The results indicate significant seasonal variations in wind characteristics. The highest wind speeds occur in July, coinciding with the peak of the southeast monsoon season. Conversely, wind speeds tend to decrease during the transition seasons (March–May and September–November). Dominant wind directions also vary throughout the year, with southerly and southeasterly winds prevailing during the dry season (JJA) and northwesterly winds dominating during the rainy season (DJF). The Weibull shape parameter (k = 2.260) and scale parameter (c = 3.525) indicate relatively stable wind distribution in this region. These findings provide valuable insights into coastal wind variability, which is essential for climate modeling, coastal management, and the potential development of renewable energy, particularly wind energy, in West Kalimantan.
