“…Karst areas are rock formations formed from carbonate rocks with the main composition of limestone (CaCO3) and dolomite (CaMg(CO3)2) (Ford and Williams 2007;Bahri et al 2020). Morphologically, karst areas can form a network system of cavities that can create water storage in springs and underground rivers.…”

Soil moisture content is a crucial factor in hydrological studies as it helps to determine the rainfall and runoff response in the catchment. Land use, particularly cropping, can have a significant effect on soil moisture content. Hilly topography with karst features is more prone to flooding and soil erosion due to its low water holding capacity. Remote sensing technology has recently been applied to agriculture and disaster management. The aim of this research is to identify soil moisture characteristics in karst formations for runoff estimation using remotely sensed imagery from Sentinel-1. Soil moisture is calculated using the Topp model equation based on the soil dielectric value obtained from the Dubois model. By using different types of land use and soil moisture data from Sentinel-1, CN values can be generated and then used to estimate runoff. The results of the study show that extracting soil moisture information from Sentinel-1A with VV polarisation for karst areas is still challenging due to the high bias. The Sentinel-1 satellite soil moisture products could provide a real-time CN value that can be integrated with the rainfall runoff model. This research highlights the importance of monitoring soil moisture to determine CN values for flood mitigation.

Tujuan pengabdian ini adalah untuk memberikan pemahaman kepada para pelaku teknik yang secara langsung berhubungan dengan masyarakat. Pengabdian ini mengenalkan system pengisian baterai nirkabel dengan induksi electromagnet. Materi system pengisian baterai disampaikan dengan cara dikenalkan kepada para beberapa teknisi bengkel-bengkel listrik dan elektronika yang mempunyai pelanggan masyarakat umum. Pengenalan materi dilaksanakan dengan metode demonstrasi yaitu memberikan paparan materi dengan alat peraga hingga kemudian memberikan kesempatan pada peserta untuk bersentuhan langsung dengan benda kerja yang dipelajari dan memperagakanya. Untuk mengetahui pemahaman peserta dilaksanakan uji coba praktik langsung merakit dan melakukan tes running serta menguji benda kerja sampai dengan berhasil fungsi pengisi baterai. Hasil pelaksanaan pengenalan dinilai sangat efektif dapat memberikan pemahaman secara langsung terkait system pengisi baterai nirkabel.
