However, this effort...

Abstract Kelumbayan Subdistrict is one of the tourist destinations in Lampung Province, Sumatra Island, Indonesia, that holds beauty sea and beaches as an attraction for tourists. However, location around Indian Ocean subduction zone makes this area prone to tsunamis due submarine earthquakes generated by meeting between Indo-Australian Plate Euro-Asian Plate. Referring case Aceh tsunami 2004, potential damage a disaster from south enormous, with many fatalities massive material losses. The...

Abstract. Land cover change (LCC) is one of the most important global environmental issues in this modern era. that occurs at local scales can impact ecosystems due to cascading effects. The relationship between human population growth, urbanization, and land resource pressures various spatial temporal has led these changes. In Bandung City, increase urbanization over years a decrease resources worsening disasters climate change. This includes Cikapundung watershed, where transformations...

Wai U Village has a problem with the limited capacity of village's clean water supply system. This community service activity aims to retrofit existing system, which previously experienced technical problems, and increase The implementation method consists pre-site visit interviews, field surveys, geoelectric surveys determine aquifer potential, quality laboratory tests for drinking standards. results data analysis show that potential was located at 30m below surface. test groundwater...

Abstract Java Island is one of the most densely populated islands in Indonesia, with a total population 152 million. The continuous increase has led to rise disaster vulnerability, including flood disasters. Since 2012, frequency floods continuously increased, an average annual 13.18%. Global-scale-river models were developed evaluate effects runoff forcings on food hazard, droughts, and water resources management. Island, limitations data storage management, resulting some areas having...

Located in the Special Capital Region of Jakarta (DKI Jakarta), which serves as government capital and national Indonesia, Ciliwung River plays a major role Indonesia. The increasing population Bogor area has resulted an increase level land ownership, had impact on areas settlement decreasing green open spaces. This rapid urbanization change use directly affected hydrological nature area, causing flooding volume this region. research was conducted four stages: analysis, hydraulic flood...

Climate change-induced alterations in temperature and precipitation patterns pose a significant threat to flood risk worldwide. This research focuses on Java Island presents method develop hazard index map considering various future climate change scenarios. To simulate characteristics for scenarios, an RRI (Rainfall-Runoff-Inundation) model was calibrated validated using six different events three basin areas. Furthermore, the baseline, historical 100-year return period, compared against...

Land use change are become issues for many river basin in the world, including Cikapundung River Basin West Java. is one of main water sources Bandung City supply system. In other hand, as tributaries Citarum River, also contributes to flooding Southern part Bandung. Therefore, it important analyze effect land on discharge, maintain reliability system and minimize Basin. map 2009 shows that residential area (49.7%) mixed farming (42.6%), most dominant type, while dry agriculture (19.4%)...

The Majalaya area is one of the most valuable economic districts in south Greater Bandung, West Java, Indonesia, and experiences at least six floods per year. are characterized by a sudden rise water level approximately to two hours after rain occurs. With aim reducing flood risk, this study models data-driven method for predicting inundation height across Watershed. maps selected events were modeled using HEC-RAS 2D numerical model. Extracted data from model, GSMaP satellite rainfall data,...

Dalam sistem pengembangan daerah Provinsi Jawa Tengah, Pemerintah provinsi menetapkan Kota Pekalongan sebagai salah satu wilayah strategis untuk pertumbuhan ekonomi. Meskipun memiliki potensi yang signifikan, masih perlu mencari solusi mengurangi banjir merupakan masalah berulang. Banjir di disebabkan oleh gelombang pasang (rob) dan luapan terjadi sungai-sungai melintasi kota. Menurut Bappeda Pekalongan, pada tahun 2020 genangan seluas 1.177,86 hektar. Untuk mengatasi banjir, pemerintah...

Indonesia, located in the "Ring of Fire" zone, is a tsunami-prone area, especially those earthquake-induced. Therefore, tsunami early warning system crucial for reducing potential damage. Ina-TEWS an Indonesian that relies on buoys, uses seismic sensors to detect tsunami, sends out its within 5 min. requires maintenance and supervision, since 22 buoys were declared lost or damaged 2012–2018. Indonesia needs faster more reliable backup system. This study proposes new method by integrating...
