Abstract

Flash flood susceptibility in upstream watersheds is influenced not only by rainfall intensity but also by the spatial configuration of physiographic characteristics and land use. The Banyuputih Watershed in East Java has experienced recurrent flash floods, emphasizing the need for spatial assessment to support effective mitigation planning. This study develops a flash flood susceptibility map using a GIS-based multi-criteria approach integrated with logistic regression. The analyzed factors include DEM-derived topographic parameters (elevation, slope, Topographic Position Index (TPI), Topographic Wetness Index (TWI), and plan curvature), Hydrologic Soil Group (HSG), rainfall, river density, land cover, and NDVI. The relative influence of each factor was determined from logistic regression coefficients. The results classify the watershed into five susceptibility levels: very low, low, moderate, high, and very high. High to very high susceptibility zones are spatially limited and mainly concentrated in upstream and parts of midstream areas characterized by flow-convergent topography and less protective land cover. Most of the watershed is dominated by very low to moderate vulnerability, indicating that flash flood potential is spatially localized. The resulting map provides a scientific basis for watershed management, land-use planning, and targeted nature-based mitigation strategies.

Abstract

The Semajid River Basin (DAS) faces complex environmental problems, including flooding during the rainy season, drought during the dry season, increased river sedimentation, and uncontrolled land use changes. This study aims to assess the performance of the Semajid Watershed in accordance with the Minister of Forestry Regulation Number 61 of 2014 on Monitoring and Evaluation of Watershed Performance, and to formulate strategies to improve watershed performance through land-cover optimization scenarios. The watershed performance assessment includes criteria for land, water management, socio-economics, building investment value, and space utilization. The evaluation results show that the Semajid Watershed performance value is 113.75, which indicates that the watershed is in the category of needing to be saved. The application of the additional land cover scenario has a significant impact on improving the criteria for vegetation cover and protected areas. The Percentage of Permanent Vegetation Cover (PPV) increased from 5.5% (very high recovery category) to 32.44% (low recovery category), while the value of the protected area criteria decreased from 68.64 to 9.37, indicating an improvement in the ecological condition of the watershed. Although the watershed's carrying capacity increased to 107.5, the Semajid watershed remains in need of restoration. Therefore, restoration of the Semajid watershed requires integrated management that sustainably integrates technical and non-technical efforts.

Abstract

Kejadian longsoran yang dipengaruhi hujan sering terjadi di Indonesia. Hujan dipahami sebagai faktor yang dapat mempengaruhi peningkatan tekanan air pori dan kenaikan muka air tanah. Penelitian ini menggunakan data pengeboran, sifat mekanik, data curah hujan harian, kondisi hidrogeologi, dan data gempa. Longsoran yang terjadi merupakan longsoran dangkal, dengan kedalaman bidang gelincir 3 meter dibagian atas lereng dan 7 meter dibagian bawah lereng. Bidang gelincir longsoran memiliki bentuk rotasional. Material penyusun longsoran terdiri dari tanah dan batuan yang berasal dari pelapukan batuan vulkanik. Penampang bawah permukaan menunjukkan bahwa terdapat kontak antara breksi tufan lapuk sedang dan breksi tufan lapuk tinggi yang berperan sebagai bidang gelincir. Geologi lereng tersusun dari lava andesit-basaltik, breksi tufan lapuk sedang dan breksi tufan lapuk tinggi. Longsoran dangkal terjadi setelah dipengaruhi hujan hari-hari sebelumnya yang mempengaruhi peningkatan tekanan air pori. Proses terjadinya longsoran diawali dengan munculnya rekahan tarik. Hasil analisis menunjukkan pengaruh curah hujan tinggi secara drastis mempengaruhi penurunan matric suction pada lereng yang menyebabkan terbentuknya rekahan tarik. Pemodelan dilakukan dengan dua simulasi yaitu simulasi dengan pengaruh hujan pendahuluan durasi 47 hari dan pengaruh hujan durasi 10 hari dengan kondisi awal sama. Hasil analisis menunjukkan hujan pendahuluan 47 hari mempengaruhi terjadinya longsoran dibandingkan dengan curah hujan pendahuluan selama 10 hari. Hasil pemodelan durasi 10 hari memiliki nilai faktor keamanan yang lebih tinggi, menunjukkan tidak sesuai keadaan di lapangan karena mengabaikan kondisi hidrogeologi hari sebelumnya. Mekanisme terjadinya longsoran pada area penelitian dipengaruhi oleh tekanan air pori, rekahan tarik dan gempa bumi sehingga didapatkan faktor keamanan sebesar 0.986.

Abstract

The Frequency Ratio (FR) method combined with Geographic Information Systems (GIS) was applied to map groundwater potential in the Bedadung Watershed, Jember Regency, Indonesia. The study was conducted from September 2024 to January 2025 by analyzing 136 spring locations across an area of 9,590.83 km². The main objectives were to identify factors influencing groundwater potential, validate the predictive model using the Area Under the Curve (AUC) method, and produce a detailed groundwater potential map. A total of 14 environmental parameters were considered, including Elevation, slope, and vegetation density. Model validation produced an AUC value of 73.8%, indicating a good level of predictive accuracy. The highest groundwater potential was observed in the sub-districts of Sukorambi, Arjasa, Sukowono, and Kalisat, where more than 50% of the area falls into the very high potential category. In contrast, Panti Sub-district demonstrated limited groundwater availability, with 59% of its area classified as low to very low potential. The resulting groundwater potential map was classified into five categories: very low, low, moderate, high, and very high. These findings provide a scientific basis for sustainable water resource management, emphasizing conservation strategies in high-potential areas and infrastructure development in low-potential zones. The effectiveness of the FR method in spatial analysis is reaffirmed, offering valuable insights for groundwater management in the Bedadung Watershed.

Abstract

Abstrak Drainase konvensional menghadapi tantangan yang diperparah oleh peningkatan limpasan permukaan. Rain barrel adalah salah satu teknik Low Impact Development (LID) yang menyediakan penampung sementara yang berpotensi mengurangi limpasan. Oleh karena itu, penelitian ini menyelidiki penerapan rain barrel untuk meningkatkan ketahanan terhadap banjir di Mastrip Housing. Menggunakan Storm Water Management Model (SWMM), limpasan hujan dimodelkan dalam kondisi sebelum dan sesudah implementasi di 71 subcatchment untuk menilai dampak infrastruktur LID. Hasilnya mengungkapkan bahwa rain barrel dapat mengurangi puncak limpasan sebesar 11% hingga 51%, dengan rata-rata pengurangan sebesar 12%. Efektivitasnya bervariasi, dipengaruhi oleh kepadatan rain barrel, cakupan area, dan penggunaan lahan. Ada tren yan menunjukkan subcatchment dengan area kecil dan unit rain barrel lebih banyak menunjukkan pengurangan peak runoff yang lebih besar, menekankan pentingnya pertimbangan rasio. Meskipun demikian, penelitian ini menemukan bahwa penggunaan rain barrel tidak selalu berhasil dalam semua situasi. Sementara mereka mungkin efektif dalam meminimalkan limpasan di beberapa lokasi, efektivitasnya bervariasi di tempat lain bahkan di area perumahan yang sama. Oleh karena itu, metode infiltrasi LID dapat dipertimbangkan untuk meningkatkan efektivitas pengurangan. Penelitian ini memberikan wawasan bagi pengembang properti menuju perumahan ramah lingkungan dan pembangunan berkelanjutan dengan penerapan rain barrel dan LID. Kata kunci: Low-Impact Development (LID), Strategi, Stormwater Management Model, Rain Barrel, Peak Runoff Abstract The conventional drainage face challenges exacerbated by increased surface runoff. Rain barrels are one of the Low Impact Development (LID) techniques that provide temporary storage which potentially can reduce runoff. Therefore, this study investigates the application of rain barrels to enhance flood resilience in Mastrip Housing. Using the Storm Water Management Model (SWMM), rainfall runoff was modeled under pre- and post-implementation conditions in 71 sub-catchments to assess LID infrastructure impact. Results reveal rain barrels can reduce peak runoff by 11% to 51%, averaging a 12% reduction. The effectiveness varies, influenced by rain barrel density, area coverage, and land use. There is trend revealed, exhibiting sub-catchments with small area and more rain barrel unit showing bigger peak runoff reductions, emphasizing the necessity of ratio consideration. Nonetheless, this study finds that the usage of rain barrels is not equally successful in all situations. While they may effectively minimize runoff in some locations, their efficacy varies elsewhere even in the same housing area. Therefore, infiltration LID methods can be considered to improve the effectiveness of reduction. This study provides insights for property developers towards environmentally friendly housing and sustainable development with rain barrel and LID implementation. Keywords: Low-Impact Development (LID), Strategy, Stormwater Management, Rain Barrel, Peak Runoff

Abstract

Drought poses severe risks to agricultural sustainability in climate-vulnerable regions. This study compares AutoRegressive Integrated Moving Average (ARIMA) and Fuzzy Time Series–Markov Chain (FTS-MC) models for multi-timescale Standardized Precipitation Index (SPI) forecasting in the Slahung sub-watershed, East Java. Historical monthly rainfall data were transformed into SPI series to model seasonal behaviors and uncertainty transitions. Evaluated via Mean Squared Error (MSE), ARIMA demonstrated superior numerical accuracy in capturing temporal and seasonal trends. Conversely, FTS-MC provided complementary probabilistic insights into drought state transitions under high climatic variability. Integrating these deterministic and probabilistic approaches enhances drought-prediction robustness, offering water resource managers a comprehensive framework for climate risk mitigation.

Abstract

Drought, a persistent state of water scarcity, is a critical challenge for agriculture and resource management. This study examines drought variability in Lamongan Regency from 2021 to 2023 using the Temperature Vegetation Dryness Index (TVDI) derived from Landsat 8 imagery, integrating Land Surface Temperature (LST) and NDVI to classify conditions from wet to dry. Results show the largest moderate drought in June 2021 (1,660.39 km²) and the most extensive severe drought in October 2023 (1,561.39 km²). In 2023, wet-normal conditions dominated early months, while dry areas expanded in the peak dry season. In this study, TVDI was derived using a simplified global normalization of LSTmin and LSTmax rather than the standard pixel-by-pixel NDVI-LST triangular feature space, which is acknowledged as a methodological limitation. An anomaly occurred in February, where high rainfall coincided with widespread dryness. Furthermore, validation with rainfall data showed a very weak correlation (R2 =0.090). This low correlation indicates a distinct time lag between precipitation events and soil moisture response, as well as the strong influence of local evapotranspiration and soil water retention capacity rather than rainfall alone. This study demonstrates that while TVDI is useful for rapid drought mapping, integration with local hydrological parameters is essential for improved accuracy.

Abstract

Flash floods are among the most frequent natural disasters caused by heavy rain associated with a severe thunderstorm, which leads to social and economic losses in infrastructure and agriculture. Therefore, this research aims to map flash flood potential susceptibility (FFPS) in the Pekalen watershed, using Geographic Information System (GIS) technology and statistical analysis to reduce the risk of flooding. The opinion and experience of an expert on the weight assessment method were carried out using the Analytical Hierarchy Process (AHP). Furthermore, the probability statistical methods and GIS were used in flash flood areas in the Pekalen watershed in Andungbiru, Probolinggo village. This study was carried out using geomorphological factors, namely elevation, slope, stream power index, and topographic wetness index, with a resolution of 30 m. Thematic map scale of the land use, river density, distance to the river, rainfall, and geology is in the ratio of is in a ratio of 1:25.000. Imagery processing was carried out using Landsat 8 30 m x 30 m resolution imagery, such as the Normalized Difference Vegetation Index. The result showed that the model map of FFPS obtained low 8%, low 23%, moderate 27%, moderate to high 26%, high 13%, and very high 2% index values. The next stage of modeling analysis led to validation using statistic receiver operating Characteristic Curve (ROC) of area Under Curve (AUC) with a value of 90.15. In conclusion, the factors that significantly trigger flash floods are distance to the river, land use, and slope.
