Abstract

: Tanah adalah komponen penting manusia. Salah satu parameter untuk mengetahui jenis tanah, serta sifat fisik dan mekanis tanah adalah dengan parameter uji permeabilitas. Sehingga perlu untuk mengetketahui berapakah nilai koefisien permeabilitas. Nilai koefisien permeabilitas digunakan untuk mengetahui jenis dan sifat fisis juga mekanis tanah di daerah Kalijaga Lombok Timur. Parameter Permeabilitas adalah parameter untuk mengetahui kemampuan tanah untuk meloloskan air. Metode yang digunakan adalah dengan pengambilan sampel tanah utuh (undisturbed soil sampel). Kemudian di uji dengan metode uji permeabilitas jenis Constan Head Test. Dan diperoleh hasil bahwa dari sampel sampel 1,2,4 dan 5 diinterpretasikan sebagai jenis tanah lanau padat, lanau lempung, dan lanau tidak murni yang dikategori sebagai permeabilitas sangat rendah (very low permeability). diinterpretasikan sebagai jenis tanah pasir sangat halus, pasir lunak, dan lanau tidak padat yang dikategori sebagai permeabilitas rendah (low permeability). Tanah dengan nilai permeabilitas yang rendah membutuhkan waktu yang lama untuk meloloskan air. Jika hal ini terjadi dalam waktu lama akan menyebabkan bencana longsor terutama di daerah berlereng.

Abstract

Meskipun jumlah ketersediaan air mencukupi, namun bila dalam pendistribusian air tidak diatur dengan baik, maka hal ini dapat menyebabkan tidak dapat mencukupi seluruh areal yang direncanakan. Hal ini tentu dapat menyebabkan terjadinya penurunan efisiensi karena lemahnya pengelolaan jaringan irigasi, yang dapat meningkatkan kehilangan air karena rembesan, perkolasi, dan pendistribusian air yang tidak tepat. Kinerja suatu saluran irigasi ditentukan oleh efisiensi distribusi air, keseragaman, dan kecukupan air. Penelitian ini bermaksud untuk mengevaluasi jaringan saluran irigasi Sekunder Bendung Gebong dan menghitung ketersediaan dan kebutuhan air.

Abstract

Sakenan Temple is one of the most sacred and historic temples in Bali. Located on Serangan Island. In addition, Sakenan Temple is an area located in the tectonic pile zone that causes earthquakes. The purpose of this study was to examine possible land movement near Sakenan Temple in Bali in attempts to lessen local calamities. The sentinel 1-A picture data from August 2022–2024 is used in this research methodology. processed on SNAP software with the DinSAR approach to extract variables related to land movement. According to the findings, there was land movement in August 2022–2023 from -0.109 to 0.145 cm/year and in August 2023–2024 from -0.245 to 0.207 cm/year. Negative numbers indicate land subsidence, while positive values indicate uplift. There is an increase in land movement, with an average of -0.158 cm/year for land subsidence and 0.176 cm/year for uplift between August 2022 and August 2023 and -109 cm/year between August 2023 and August 2024. The value of land movement increased, increasing by -0.178 cm/year. The average is -0.156.

Abstract

Groundwater availability is an essential factor in supporting domestic activities, agriculture, and tourism development in Sajang Village, East Lombok, Indonesia. Nevertheless, scientific information regarding subsurface groundwater potential in this volcanic region remains limited. The research contribution is the evaluation of subsurface lithology and groundwater aquifer potential in Sajang using the Vertical Electrical Sounding method to support groundwater exploration planning. This research applied the Vertical Electrical Sounding (VES) technique with the Schlumberger electrode configuration at two observation points. Field measurements were processed through inversion analysis using IP2WIN software to obtain true resistivity values and interpret lithological characteristics beneath the surface. The interpretation results reveal that the subsurface structure is dominated by volcanic rocks consisting of overburden, andesite lava, and andesite breccia with generally high resistivity values. At the first sounding point, resistivity values range from 77.8 Ωm to 11 × 107 Ωm at depths reaching 150 m. Meanwhile, the second sounding point shows resistivity values between 17.2 Ωm and 44 × 105 Ωm at depths of up to 153 m. The absence of low-resistivity zones indicates that productive aquifer layers are not present within the investigated area. Consequently, groundwater drilling activities are not recommended at the measurement locations. This study provides updated hydrogeophysical information for groundwater assessment in volcanic terrains of East Lombok.

Abstract

Landslides are a disaster that can occur at any time without warning. Therefore, identifying areas with the potential to become slip surfaces is a crucial mitigation step. The risks and losses from these disasters can be minimized or even avoided. One method used to identify potential landslide areas is the geoelectric method. This study used the Wenner configuration resistivity method. This study, conducted on two tracks, indicated the potential for slip surfaces ranging from moderate to very deep. With resistivity values ??of 23–503 ohm.m, the soil is interpreted as clay and is indicated as a potential landslide area at a depth of 2–15 meters

Abstract

Local geological conditions strongly influence seismic-wave propagation and earthquake ground response, particularly in heterogeneous volcanic environments. This study aimed to characterize shallow subsurface conditions and assess local seismic site response in Setiling Village, Central Lombok, Indonesia, by integrating two-dimensional Electrical Resistivity Tomography (ERT) using the Wenner–Schlumberger configuration with Spatial Autocorrelation (SPAC)-based microtremor analysis. Three ERT profiles and twenty SPAC measurement points were acquired to evaluate subsurface heterogeneity and near-surface stiffness. The ERT results revealed significant resistivity variations associated with volcanic lithology, weathering intensity, moisture content, and groundwater conditions. Conductive zones (<100 Ωm) were interpreted as highly weathered volcanic deposits, whereas higher resistivity zones (>600 Ωm) represented relatively competent volcanic materials. SPAC-derived Vs30 values ranged from 150 to 525 m/s, corresponding to NEHRP Site Classes C, D, and E. Integrated interpretation demonstrated a consistent relationship between resistivity and Vs30, indicating that progressive volcanic weathering simultaneously reduces electrical resistivity and subsurface stiffness. The integrated ERT–SPAC approach provides a reliable framework for village-scale seismic site characterization, supporting seismic hazard assessment, risk-informed spatial planning, resilient infrastructure development, and disaster risk reduction in tropical volcanic regions.
