Abstract

This research analyzes the dynamics of land cover change in the Puncak Area over the last 10-year period (2013-2023). Using the Random Forest Classification method on Landsat 8 and 9 image data, this study evaluates the contribution of tourism to the economy of the Puncak Region and reveals facts related to land use change. The Puncak area, known as a mountain tourism destination in West Java, is experiencing rapid economic growth, but tourism activities and infrastructure development have the potential to negatively impact local ecosystems. The research used BIG administrative data, Landsat imagery, and landform systems for analysis. Through Google Earth Engine (GEE), data processing was performed, including cloud masking, mosaic, clip, and pan-sharpening. The Random Forest classification method was used to determine land cover in 2013 and 2023 with kappa accuracy tests reaching 85.81% and 88.42% respectively. The results show an increase in built-up land area of 4,632.68 hectares with a decrease in agricultural and forest land. Obstacles in the interpretation of low-resolution Landsat imagery became one of the challenges in this study. The Urban Expansion Intensity Index (UEII) calculation results show a moderate increase in built-up land area over the past 10 years. The phenomenon of urbanization and the drive of economy and tourism are the main factors of land change from vegetation cover to built-up land. This study provides important insights for the regulation and monitoring of the Puncak Area to maintain a balance between economic growth and environmental sustainability.

Abstract

This paper explores the critical role of physical geological environments in driving geotourism-based village tourism development in Indonesia, with case studies from Tourism Villages of Alamendah in Bandung and Limbasari in Purbalingga. Using a literature review method with a descriptive-analytical approach, the study highlights how unique geological features, combined with active community participation, contribute to sustainable tourism development. Indonesia, as a megadiverse country, possesses extraordinary geological potential, including volcanic landscapes, geomorphological formations, and mineralogical diversity, offering significant opportunities for geotourism. These natural assets not only enhance the aesthetic and educational value of tourism destinations but also support environmental conservation and local economic empowerment. Desa Wisata Alamendah exemplifies successful integration of geological potential with local economic activities, particularly through agritourism and digital innovation in tourism management. With monthly revenues reaching Rp1.3 billion, the village serves as a model for sustainable tourism. Meanwhile, Desa Limbasari leverages its geological sites, such as pillow lava and green jasper, to attract tourists, significantly benefiting residents. Despite their successes, both villages face challenges, including limited infrastructure, accessibility issues, and the need for greater community engagement. Geotourism aligns with the United Nations' Sustainable Development Goals (SDGs) by addressing poverty reduction, quality education, gender equality, decent work, climate action, and ecosystem preservation. To ensure sustainability, the study recommends strategies encompassing geoheritage certification, improved accessibility, technological adoption for interpretative purposes, and enhanced community participation. The research concludes that the physical environment plays a pivotal role in geotourism development, serving as both an attraction for tourists and a foundation for inclusive, environmentally-friendly local economic growth. By fostering collaboration among governments, tourism stakeholders, and local communities, Indonesia can harness its geological wealth to drive sustainable rural development while preserving its natural and cultural heritage.

Abstract

This study investigates urban landscape changes in Surabaya from 2014 to 2024 using NDVI and NDBI indices derived from Landsat 8 OLI imagery. The Earth Engine platform was employed to generate cloud-free composite images, enabling detailed analysis of vegetation and built-up area changes. The methodology included a bivariate geovisualization technique to display areas of change, comparing NDVI and NDBI values over a decade to assess changes at a granular level. Results indicate that the 'Vegetation Stable - Built-up Area Stable' category dominates, covering 2422 km², suggesting consistent land use in established areas. This dominance indicates well-established land use patterns across much of the city. Significant urbanization is observed in the 'Vegetation Decreased - Built-up Area Increased' (70 km²) and 'Vegetation Stable - Built-up Area Increased' (177 km²) categories, reflecting ongoing development pressures. These areas highlight zones of active development and environmental intervention. Additionally, a 75 km² increase in vegetation, particularly in coastal mangrove regions, highlights successful environmental management efforts. The study achieved an overall accuracy of 71%, demonstrating the effectiveness of NDVI and NDBI in capturing urban dynamics. While some classes require improved detection accuracy, particularly those involving decreased built-up areas, the model reliably identifies increases in vegetation and built-up areas.

Abstract

Sustainable water resource management must consider climate change to minimize climate disasters. The water resources of Bintan island are limited, although rainfall is quite high, but the small catchment area and the component rocks of the island of Bintan have low water retention capacity. Currently, Bintan Island is experiencing an increase in water needs due to population growth and economic activities. Therefore, understanding changes in seasonal rainfall in the future is important on this island. This paper aims to study the chances of future seasonal rainfall variability using long-term projection climate modeling. Currently, a high-resolution climate model is available for historical and future periods, namely CORDEX-SEA for the Southeast Asia region. Because the study area is a small island with an area of around 1170 km2, the resolution of the CORDEX-SEA projection climate model data is insufficient. This study uses a statistical downscaling method with quantile mapping to detail the spatial resolution. The results of the analysis show that rainfall on Bintan Island is likely to change in the future due to climate change. Rainfall in Bintan Island in the future will likely be below normal rainfall in all seasons, except in the northern part of Bintan in the SON season. The greatest posibility of rainfall is below normal rainfall in the JJA season. The analysis results show that the eastern part of Bintan Island is a suitable area to build a water reservoir for managing water shortages in Bintan island caused by potentially decreasing rainfall in the future.

Abstract

Flash flood is a geomorphic hazard that can cause huge losses in a short period of time. Cianjur regency, especially Cikundul Watershed is a flash flood frequent area. Therefore, flash flood potential mapping is needed to reduce the threat that can be caused by flash flood. In the flash flood potential mapping, Flash Flood Potential Index (FFPI) method is still rarely applied in Indonesia. This study aims to see the comparison of flash flood potential areas based on models developed in the FFPI method which is Smith, Brewster, Krudzlo, and Ceru models. The four models used slope, land use, soil texture, and vegetation cover as variables. Spatial analysis and statistical test was implemented to validate the flash flood potential areas with flash flood affected locations. The result reveals that Cikundul Watershed was dominated by moderate potential areas based on Brewster, Krudzlo, and Ceru model but low by Smith model. The result also reveals that 65% of 68 Sub-Sub Watershed have different potential and 35% have same potential. High potential areas in all four models was distributed in the Upper Cikundul Watershed. The Crosstab Fit Test result shows that Smith model is the closest model to the actual event.

Abstract

Forest and land fires in Indonesia take place almost every year, particularly in the dry season and in Sumatra and Kalimantan. Such fires damage the ecosystem, and lower the quality of life of the community, especially in health, social and economic terms. To establish the location of forest and land fires, it is necessary to identify and analyse burnt areas. Information on these is necessary to determine the environmental damage caused, the impact on the environment, the carbon emissions produced, and the rehabilitation process needed. Identification methods of burnt land was made both visually and digitally by utilising satellite remote sensing data technology. Such data were chosen because they can identify objects quickly and precisely. Landsat 8 image data have many advantages: they can be easily obtained, the archives are long and they are visible to thermal wavelengths. By using a combination of visible, infrared and thermal channels through the semi-automatic object-based image analysis (OBIA) approach, the study aims to identify burnt areas in the geographical area of Indonesia. The research concludes that the semi-automatic OBIA approach based on the red, infrared and thermal spectral bands is a reliable and fast method for identifying burnt areas in regions of Sumatra and Kalimantan.

Abstract

Hydrologic Response Unit (HRU) is a unit formed of hydrological analysis based on geology and soil type, slope, and land cover. This paper discussed the spatial pattern of Hydrologic Response Unit (HRU) in 1997-2009 and its impact on flow Ci Rasea watershed temporally. In this study, SWAT (Soil and Water Assessment Tool) model, based on land cover changed, was used to get HRU and flow in spatially and temporally. This method used Landsat TM 1997, 2003 and 2009 data for land cover and daily rainfall 1997-2009 for flow modeling. The results showed the spatial pattern of HRU in temporally was affected by landcover based on the changing of HRU. The majority of HRU spatial pattern at Ci Rasea watershed were clustered. During 1997-2009, accumulated surface runoff and the changing of flow discharge were affected by changes of HRU spatial pattern. The biggest accumulated surface runoff in Ci Rasea watershed influenced by HRU of agricultural cropland in area of clay soil type with slope slightly obliquely. While the smallest accumulated surface runoff in Ci Rasea watershed influenced by HRU of paddy field in the area of sandy loam soil type with a gentle slope. The changes of HRU agriculture cropland become HRU mixed cropland in area clay soil type with slope at a slight angle and HRU agriculture cropland become HRU paddy field in area, sandy loam soil type with a gentle slope could be decreasing the accumulation of surface runoff in Ci Rasea watershed.

Abstract

. This paper discusses spatial pattern of Hydrologic Response Unit (HRU), which is a unit formed of hydrological analysis, including geology and soil type, elevation and slope, and also land cover in 2009. This paper also discusses the impact of HRU on streamflow of Ci Rasea watershed, West Java. Ci Rasea watershed is located at the upstream part of Ci Tarum watersheds in West Java Province, Indonesia. This research used SWAT (Soil and Water Assessment Tool) model to obtain spatial HRU and river flow. The method used Landsat TM data for land cover and daily rainfall for river flow modeling. The results have shown spatial pattern of HRU which was affected by land cover, soil type and slope. In 2009, accumulated surface runoff and streamflow changes were spatially affected by HRU changes. The large amount accumulation of river flow discharge happened in HRU with landcover paddy field, silty clay soil, and flat slope. While the low discharge of river flow happened in HRU with plantation, clay soil, and slightly steep slopes as HRU dominant. It was found that accumulation of surface runoff in Ci Rasea watershed can be reduced by changing the land cover type in some areas with clay and slightly steep slope to become plantation area and the areas with sandy loam soil and flat slope can be used for paddy fields. Beside affected by HRU, the river flow discharge was also affected by the distance of sub watershed to the outlet. By using NS model and statistical t-student for calibration and validation, it was obtained that the accuracy of river flow models with HRU was 70%. It meant that the model could better simulate water flows of the Ci Rasea watershed.

Abstract

Land use and land cover change (LULCC) is a key indicator for understanding regional spatial dynamics, particularly in disaster-affected areas. Palu City, which experienced severe liquefaction in 2018, requires detailed land cover change analysis to support disaster-responsive regional development and spatial planning. This study aims to analyze land cover change dynamics in Petobo Sub-district before and after the 2018 liquefaction event using Pleiades imagery and aerial photographs from 2017, 2018, and 2022. A quantitative remote sensing approach was applied, employing automated classification on the Google Earth Engine (GEE) platform using the Random Forest (RF) method, followed by spatial analysis using ArcGIS Pro. The classification results demonstrate high accuracy, with Kappa coefficients of 0.82 in 2017 and 2018, and 0.86 in 2022. The analysis reveals significant land cover changes due to the 2018 liquefaction, particularly a reduction in built-up areas of more than 50%, from 25.03% in 2017 to 12.16% in 2018, before increasing to 15.60% in 2022. The dominance of low vegetation cover, reaching 58.46% in 2022, reflects post-disaster land-use adaptation and policy changes. These findings confirm the effectiveness of remote sensing technologies in supporting post-disaster regional development planning.

Abstract

Perubahan penggunaan dan tutupan lahan (LULCC) terus meningkat seiring pertumbuhan kebutuhan lahan manusia, terutama akibat urbanisasi. Dinamika tersebut memerlukan pendekatan terpadu yang menggabungkan analisis geospasial, evaluasi kebijakan, dan keterlibatan pemangku kepentingan untuk mendukung pengambilan keputusan yang lebih baik. Penelitian ini bertujuan menganalisis perkembangan kajian LULCC dalam kaitannya dengan kebijakan perencanaan tata ruang melalui analisis bibliometrik dan tinjauan pustaka sistematis, serta membandingkan fokus, tujuan, sumber data, metode, dan temuan penelitian terdahulu. Sebanyak 139 artikel ilmiah yang terbit pada periode 2018–2024 dianalisis menggunakan metode Systematic Literature Review (SLR) dan pendekatan bibliometrik untuk mengidentifikasi tren penelitian, tema utama, serta jaringan kolaborasi internasional. Hasil penelitian menunjukkan bahwa urbanisasi merupakan pendorong utama LULCC, yang ditandai oleh peningkatan kawasan terbangun dan penurunan lahan pertanian serta ruang hijau. Kebijakan tata ruang berperan penting sebagai instrumen mitigasi dan pengendalian dampak LULCC terhadap ekosistem. Selain itu, teknologi penginderaan jauh dan model spasial semakin dominan digunakan untuk memantau perubahan lahan, menilai dampak lingkungan, serta mendukung perumusan kebijakan. Pendekatan yang mengintegrasikan aspek spasial, kelembagaan, dan partisipatif diperlukan agar perencanaan tata ruang mampu merespons perubahan penggunaan lahan secara efektif. Efektivitas kebijakan juga dipengaruhi oleh ketersediaan data, kapasitas kelembagaan, konsistensi implementasi, pemantauan berkala, serta koordinasi antarsektor dan antarwilayah dalam menghadapi tekanan urbanisasi dan perubahan lingkungan pada masa mendatang. Penelitian ini menegaskan pentingnya penguatan kebijakan berbasis bukti yang menghubungkan hasil analisis ilmiah dengan kebutuhan pembangunan. Temuan penelitian memberikan rekomendasi bagi pembuat kebijakan untuk menyeimbangkan pembangunan perkotaan, perlindungan ekosistem, dan konservasi lingkungan melalui tata ruang yang adaptif, kolaboratif, dan berkelanjutan.
