The Analysis of the Effect of Population Growth on Changes in Built-Up Area Density in Kupang City in 2020 and 2024 Using the Normalized Difference Built-Up Index (NDBI) Method
The dynamics of urban development in Kupang City are strongly influenced by population growth and the increasing need for urban space. This study aims to analyze the relationship between population growth and changes in built-up area density in 2020 and 2024 using the Normalized Difference Built-Up Index (NDBI) from Landsat 8 OLI/TIRS Level-2 imagery. This study uses a spatial quantitative approach with the integration of remote sensing techniques, geographic information systems (GIS), and statistical analysis. Population data were obtained from the Central Statistics Agency (BPS) of Kupang City, while spatial data were from the USGS with a path/row of 110/070 and a cloud-free acquisition rate of <10%. Image processing includes atmospheric correction (LaSRC), cloud masking, cropping of administrative boundaries, and calculation of the NDBI index. NDBI values are classified into three categories: low ( −0.2–0.0), medium (0.01–0.2), and high (>0.2) based on the reference of Dewi et al. (2023). Field validation was conducted at 20 sample points with an accuracy of 87%. The results show a significant increase in built-up areas in Maulafa, Alak, and Oebobo, which aligns with the population growth trend in these sub-districts. Pearson's correlation (r = 0.418) indicates a positive relationship between population growth and built-up density. This finding confirms the relevance of the NDBI as a tool for monitoring urbanization in medium-sized cities in Eastern Indonesia

The Spatial Analysis of Population Structure Towards Demographic Bonus in Pesisir Barat Regency of Lampung
The demographic bonus represents a strategic development opportunity that can only be optimized when population structure is supported by adequate social, economic, and spatial readiness. In Pesisir Barat Regency, disparities in productive-age population distribution, high dependency ratios, unemployment rates, and rapid population growth remain key challenges in preparing for the demographic bonus. This study aims to spatially analyze the population structure based on key demographic indicators including population growth rate, dependency ratio, proportion of the productive-age population, and open unemployment rate. A quantitative approach was applied using spatial analysis techniques within a Geographic Information System (GIS) framework. All indicators were classified using range-based value categorization, visualized through thematic mapping, and integrated into a composite readiness index using a simple linear weighting method. The findings reveal that the population growth rate remains relatively high at 2.19%, driven by a persistently elevated birth rate. The dependency ratio reaches 49.87%, while the open unemployment rate is recorded at 4.12%, with spatial variation across districts. Despite these challenges, the productive-age population accounts for 69.5% of the total population, indicating substantial potential for harnessing the demographic bonus. These results emphasize that spatially informed population planning is essential for maximizing demographic potential while minimizing socio-economic disparities. Overall, this study highlights the significance of spatial demographic mapping as a scientific basis for formulating targeted development policies to ensure the demographic bonus translates into sustained regional progress.

A Assessment of Potential Damage and Loss of Subak Land Use Due to Flood Hazard in South Denpasar District, Denpasar City
South Denpasar District has an elevation of 0–12 meters above sea level and is categorized as a lowland area, making it prone to flood disasters. Flooding can cause damage and economic losses, particularly in the agricultural sector on subak lands. This study aims to calculate the potential damage and losses in subak land use in South Denpasar. The methods used include the Topographic Wetness Index (TWI) to analyze flood and damage potential, as well as field surveys for validation and loss estimation. The data used include DEM SRTM data, the Indonesian Topographic Map (RBI), the subak boundary map of South Denpasar District, and satellite imagery from Google Satellite. Data from the Department of Agriculture include subak area data. Data from the Agricultural Extension Center (BPP) and subak heads (pekaseh) include data on the cost components of subak production per hectare. Data from the Department of Public Works, Water Resources Division, include subak irrigation data and the cost components for constructing concrete irrigation channels per meter. The results show that subak land in South Denpasar has high damage potential covering 91,732 ha (20,48%), medium damage potential at 133,548 ha (29,81%), and low or no damage at 222,701 ha (49,71%). Areas with the largest subak damage potential are Subak Kerdung and Subak Kepaon. The potential damage to subak irrigation networks is classified as high 974,07 m (8,00%), medium 4.107,12 m (33,71%), and low or none 7.101,99 m (58,29%). The longest irrigation damage potentials are found in Subak Kerdung and Subak Intaran Barat. The total estimated subak loss in South Denpasar District is calculated by summing the losses from high and medium damage potential for each variable. The estimated loss for subak production is IDR 1,564,288,000, while the irrigation loss is IDR 1,496,626,727, resulting in a total potential loss of IDR 3,060,914,727. The highest losses are found in Subak Kerdung and Subak Kepaon. Policy recommendations include strengthening irrigation infrastructure, disaster mitigation training, and preserving the subak system through land conservation.
The Spatial Analysis of the Potential and Development Opportunities for Ocean Current Power Plants (OCPP) in Lombok Strait
Entering an era where demand for electricity is increasing, renewable energy sources like the Ocean Current Power Plant (OCPP) are crucial for nations like Indonesia. The Lombok Strait, a key channel for the Arus Lintas Indonesia (ARLINDO) or Indonesian Throughflow, stands out as a strategic location for this technology due to its powerful currents. These currents have a minimum speed of 4.4 m/s and a maximum of 5.8 m/s, averaging around 5.34 m/s. This study sought to pinpoint suitable areas for OCPP development within the strait using a qualitative geographical approach, analyzing literature and satellite data. The research confirmed that current speeds ranging from 4.44 to 5.8 m/s could produce an average of 25.92 kW of power, equivalent to 181,647.36 kWh annually. Ideal locations for turbine placement ranging from 0 to 75 meters offshore, in water depths varying from 0 to -100 meters. Therefore, the study emphasizes the need for careful site selection using suitability maps and calls for further research into an effective power distribution system to successfully harness the strait's energy potential.

The Analysis of Hail Based on Atmospheric Conditions and Himawari-9 Satellite: Case Study of Surabaya City, March 20, 2023
Hail is a rare extreme weather phenomenon in Indonesia. On March 20, 2023, hail occurred in Surabaya City. The research was conducted to analyze the hail based on atmospheric conditions and the Himawari-9 satellite. Analysis of the global scale showed anomalies in sea surface temperature in the Southeast Indian Ocean. Regionally, a monsoon shear line and significant low-level moisture transport from the South Java Sea caused convergence in the Surabaya. Locally, there was a significant increase in relative humidity by 10%, and a surface temperature decrease of 3.2°C resulted in wetter surface weather. The occurrence of hail was also supported by upper air conditions, with four indices (CAPE, LI, TT, and SWEAT) falling within the moderate category. In contrast, CIN was categorized as low, while KI increased from moderate to high. A moderate CAPE index in the mid-level updraft of moist air resulted in the maximum hail size. Clouds reached the freezing level in the mid-level atmosphere at 5048 meters and 4776 meters. The RGB Day Microphysics technique using Himawari-9 satellite imagery identified overshooting tops and a drastic decrease in top cloud temperature reaching -82.5°C, indicating the presence of a strong updraft and the formation of convective clouds that surpassed the freezing level.
An Enhancing Community Disaster Resilience in Tourism Villages: Insights from West Nusa Tenggara, Indonesia
Historical records show that Lombok experienced significant damage from a tsunami triggered by geological activity in 1977. Kuta Village, located in southern Lombok, faces a high risk of earthquakes and tsunamis. This research aims to develop mitigation and preparedness recommendations for the area. Data was collected using a community preparedness survey in Kuta Village, observation with town watching, and focus group discussions. The results of the Household Preparedness Survey showed low scores in terms of knowledge, early warning, emergency response plans, and resource mobilization. Mitigation schemes in Kuta Village should prioritize improving both structural and non-structural aspects of the area. Structural measures should involve cooperation between local communities and the district government to maintain coastal vegetation. Non-structural approaches to mitigation include implementing tsunami mitigation measures into village development plans, improving community capacity, strengthening local government, and utilizing community-based early warning systems. To improve community capacity, the establishment of disaster-resilient tourism villages would be beneficial. In addition, promoting disaster-resilient families and raising tsunami awareness through locally sourced knowledge would also be useful.

The ANALYSIS OF TIDAL INUNDATION AND THE AGGLOMERATION OF LOSSES IN THE COASTAL AREA OF BONANG SUB-DISTRICT, DEMAK DISTRICT
Rob is a disaster whose impact is getting worse due to inappropriate use and management of land in coastal areas, endangering Java's coastal areas which are around 1,000 km long and more than 250 km wide, so that the total area will be threatened. more than 80,000 km of Indonesian coast (Triatmodjo, 1999; Bird and Ongkosongo, 2005). Demak Regency is one of the districts in Central Java which is located on the north coast (Pantura). According to the Demak Regency Central Statistics Agency, settlements in Demak Regency are coastal settlements that are prone to flood disasters, especially in the Bonang District area. The problem of damage due to tides in Demak Province is caused by its geographical location in coastal areas and bordering rivers with almost flat land slopes, and is exacerbated by the reduction in river watersheds due to land conversion. If sea level rise is expected to continue to increase in the long term, there are concerns that flooding due to storms will become more widespread. The impact caused is directly proportional to the area covered by the flood.The method used is a quantitative method with a spatial approach. The research results show that the physiographic conditions of Bonang District, which tend to be flat and have low land elevations, have a significant effect on the area covered by tidal flooding, reaching 71.04% of the total area. With the characteristics of Bonang District as a densely populated area, the resulting estimated losses are even greater. The distance of the moon from the earth also plays a role in determining the height of sea tides, which in turn influences the height of inundation

The Quantifying the Relationship Between ENSO-Induced SST Anomalies and Rainfall Variability in East Java’s Coastal Regions
El Nino and La Nina events affect the conditions of the rainy season and dry season, especially as a cause of flooding in coastal areas. The North Coast of Java is a coastal area that is prone to disasters due to the influence of sea level anomalies caused by the interaction of the sea and the atmosphere. The northern coast of East Java, which is directly adjacent to the coast, has a high level of vulnerability to tidal flooding or rob disasters. This study aims to examine the effect of the Nino 3.4 index on the El Nino and La Nina phases in influencing rainfall on the northern coast of East Java, especially in the areas of Tuban, Lamongan, Gresik, Surabaya City, Sidoarjo, Pasuruan, Probolinggo, and Situbondo. The method used is a correlation analysis between rainfall parameters and the Nino3.4 index to determine the relationship between parameters. The results of the study on La Nina, El Nino, and Neutral conditions have a negative relationship in almost all research locations with moderate to very low correlation values. This study provides an explanation of the relationship between rainfall and ENSO to flooding events on the northern coast of East Java.
Comparison of Sentinel-1A Ascending and Descending Image Processing Results on the Tukul Dam Using SNAP Software
This study analysed and compared the accuracy of the results of Sentinel 1A satellite image processing in the ascending and descending orbit directions with SNAP software. The research is located at Tukul Dam, Karanggede Village, Arjosari District, Pacitan Regency, East Java Province, with a range of observation data for one year in 2022-2023. Sentinel 1A satellite image processing uses the Differential Interferometry Synthetic Aperture Radar (DInSAR) method.

Mapping of Livable and Unlivable Houses for the Priority of House Rehabilitation Beneficiaries in Sambiduwur Village, Tanon District, Sragen Regency
Houses are one of the basic needs of humans. A home is a place for humans to live and shelter from climate and weather’s influence. As mandated in Pasal 28 H Amandemen Undang - Undang Dasar1945, a house is the fundamental right of the people, so every citizen has the right to get a place to live in a good and healthy environment. The citizens’ economic unpreparedness makes many Indonesians still live in unlivable houses. Based on BPS data, in 2010, there were 40.46% unlivable houses in urban and rural areas. For this reason, the Government continues to strive and protect the community so that they can live in appropriate places. The Government’s desire to improve the socioeconomic level of low and middle-income people is demonstrated through the social rehabilitation program for housing. The limited availability of data on unlivable housing makes it difficult for the Government to determine the social beneficiary’s priority. This study aims to map the livable and unlivable houses to determine the beneficiary’s importance in Sambiduwur Village. The primary data collection method used was observing the house in Sambiduwur Village. The analysis technique used identified livable and unlivable houses with scoring which refers to the criteria and indicators from the module issued by the Minister of Public Works and Housing. Determination of the level of damage to the house is guided by Appendix V, Regulation of Minister No.33/Prt/M/2016, about Technical Instructions for The Implementation of Special Allocation Funds for Infrastructure. The study results showed that 979 houses in Sambiduwur Village, 79 (8.06%) houses were classified as unlivable, and 900 (91.94%) houses were classified as livable.

Medan City is a city with a dense population. This causes residential areas in Medan Marelan tend to be densely packed. The negative impact is that are prone to fire disasters. To prevent the impact of these fires, monitoring is needed. Way of monitoring that can be done is using remote sensing. This research carried out remote-sensing by using the Himawari-9, MODIS, and VIIRS satellites. The method used are the Red Green Blue (RGB) method for the Himawari-9 satellite and the Fire Information Resource Management System (FIRMS) method for the MODIS and VIIRS satellites. Based on this research, the MODIS and VIIRS satellites are superior in monitoring small fires that occurred in Medan Marelan compared to the Himawari-9 satellite. The Himawari-9 satellite is more likely to detect clouds over fire locations than the fire itself. This was proven by radiosonde data which stated that atmospheric conditions at that time were moderately unstable. With additional information via rainfall data on November 16 2023 with a range of 20-50 mm.
