Abstract

Batu Tourism City is located in a mountainous area, so based on information from the BNPB, it has quite a large potential for landslides. Landslide hazards can frequently disrupt public traffic due to road cuts. Landslide mapping digitally will contribute to handling and mitigation activities since the database can be updated in real time to anticipate landslide hazards. This study aims to map landslide-prone areas located in the Payung zone, Songgokerto Village, and Batu City. Landslide areas can be determined by mapping analysis using GIS software. GIS can determine the classification level for a landslide susceptible area. Some input data that will influence landslides, such as rainfall, wind, earthquakes, etc., was collected as the control parameters. All parts of the study area could be classified as areas with minor, medium, and major potential for landslides. Primary data are collected from geo-surveying (aerial images) using drone devices for interpretation of landslide susceptibility areas, geophysical to identify the type of soil or rock layers that completed their behavior, and slip planes as well using geo-electric, geotechnical engineering to predict slope stability with the correlation from cone penetration test (CPT) data, and geo-hydraulic to observe the rainfall and the catchment area model using the available secondary data. Geometrically, measurement data found that the average slope angle at the upper and lower of the East Java Province highway is around 40–50o. Studies from geophysical data identified that the hilly terrain in the object study area has been dominated by the weathered rock layer. Geotechnical data obtained shows the soil layers at the slope location will be stable with the water content under 35% during the dry season and may become unstable with the water content reaching over 50% due to the increase in saturation during the rainy season. The landslide that occurred was more caused by seepage behavior from surface water flow towards the sloping plane, and then the safety factor during the rainy season reached the critical values at SF = 0.58. During the dry season, the unsaturated process due to the temperature change generates a safety factor (SF) of more than 1.2. The compilation data produced maps of susceptible landslides and surface flow distribution. Doi: 10.28991/CEJ-2023-09-04-016 Full Text: PDF

Abstract

Microtremor and geoelectrical resistivity surveys have been conducted in areas where the April 10, 2021, earthquake of 6.1 Mw caused the most damage. Wirotaman Village, Malang Regency, was one of the regions with the most extensive damage. This study aims to investigate the seismic vulnerability and subsurface conditions that result in severe damage at the research location. This study's Horizontal to Vertical Spectral Ratio Analysis (HVSR) curve was derived from the recorded microtremor signal in the frequency domain. The frequency parameter and amplification factor obtained from the curve are used to determine the seismic vulnerability index. In addition, a geoelectrical resistivity study with a dipole-dipole configuration was conducted at the site with the most extensive damage. The results of this study show the correlation between the results of the HVSR curve analysis and geoelectrical resistivity in determining the seismic vulnerability of an area. The results indicated that the high seismic vulnerability index value ranged from Kg= 12.0 to 18.0, with the most severe damage concentrated in the Southwest at SA 05 and SA 06. Based on the results of the geoelectrical survey, information was obtained that several points of damage to buildings at SA 05 (red circle) were on the same line, where this condition was associated with the possibility of new faults at that location. This microtremor and geoelectric resistivity investigation reveals thick sedimentary deposits with a high seismic vulnerability index and low resistivity. This study's findings can be utilized as a guide for micro zonation studies in research areas. This research contributes to the surrounding community in the form of disaster mitigation, where construction must avoid local fault positions that have been found to reduce the level of damage when natural geological disasters occur. Doi: 10.28991/CEJ-2023-09-09-014 Full Text: PDF

Abstract

Various geological disasters, such as landslides and ground movements, occur annually in Srimulyo Village, Malang District, with varying levels of damage. Ground movements can affect structures built above, causing sinking, cracking, and collapse. Research into landslides and ground movements triggered by vibrations is generally conducted using the microtremor method, which has proven effective. This study uses the microtremor method to map the soil condition that is potentially prone to movement or landslides based on the observed soil vulnerability index. Data was collected using a TDL 303s Digital Portable Seismograph instrument; the measurement points were established in the form of a grid distributed across the research area, with a recording duration of approximately 45 minutes at each point. The analysis technique utilizes the Horizontal Vertical Spectrum Ratio (HVSR) based on the Fast Fourier Transform (FFT) principle. The study’s results found that the research location’s seismic vulnerability index varies between 6.5 and 16.5. Areas with high seismic vulnerability index values, specifically those with Kg>11.5, are scattered on the west, south, and southeast sides of the research location. Based on field observations, these areas are dominated by relatively thick sediment layers, leading to lower dominant frequency values and higher amplification values; consequently, the seismic vulnerability index in the southern region is also high. Doi: 10.28991/CEJ-2024-010-05-017 Full Text: PDF

Abstract

Bantur District in Malang Regency is an area that is vulnerable to drought disasters. A geoelectrical resistivity survey has been conducted in Sumber Waluh Hamlet, Pringgodani Village, Bantur District, Malang Regency as an effort to mitigate drought disasters. This study aims to identify the distribution of aquifer layers based on the results of subsurface resistivity modeling. The identified aquifer layers can be used as a solution to the problem of drought disasters. In this study, geoelectrical resistivity measurements used the VES technique, i.e. the Schlumberger configuration, which was carried out at seven points. Analysis of the modeling results showed the existence of a shallow aquifer layer with a depth of 8-20 meters and a deep aquifer with a depth range of 50-70 meters. The aquifer layer has a resistivity value between 0.51-31.36 Ωm which is interpreted as a tuffaceous sandstone layer. In hydrogeological modeling, it is interpreted that the position of the groundwater level is at a depth of 40-50 meters. Thus, the results of this study can be used as a recommendation for drilling points to find new water sources in the research area.

Abstract

Penelitian ini bertujuan untuk mengungkap secara sistematis cara nilai-nilai moral diartikulasikan dalam lirik lagu “Ghibah” karya Rhoma Irama. Kajian nilai moral dan kritik sosial dalam lirik lagu ini dilakukan dengan pendekatan kualitatif deskriptif-analitis. Analisis ini merujuk pada teori sastra, semiotika, perspektif sosial, serta perspektif agama Islam. Pendekatan-pendekatan tersebut digunakan untuk mendalami penggunaan metafora, simbolisme, dan retorika dalam lirik lagu tersebut dapat membentuk pesan moral yang mendalam. Hasil penelitian menunjukkan bahwa lagu “Ghibah” tidak hanya berfungsi sebagai sarana hiburan, tetapi juga sebagai medium yang efektif dalam menyampaikan kritik terhadap praktek mengungkap aib yang sering terjadi dalam masyarakat. Rhoma Irama mengajak pendengar untuk menolak perilaku “Ghibah” dan sekaligus mengarahkan perhatian pada pentingnya introspeksi diri dan kesadaran moral dalam kehidupan sehari-hari. Pesan moral yang terkandung dalam lagu ini mengajak pendengar untuk melakukan refleksi diri, menolak budaya “ghibah”, serta menginternalisasi nilai-nilai keadilan, kejujuran, dan toleransi. Kesimpulannya, lagu “Ghibah” mampu menyampaikan kritik moral secara mendalam melalui penggunaan bahasa yang kaya akan metafora, retorika, dan simbolisme. Penelitian ini diharapkan dapat memberikan kontribusi pada pemahaman lebih luas mengenai keterkaitan antara seni musik, nilai-nilai moral, dan kritikan sosial dalam konteks budaya Indonesia.Kata kunci: Kritik Sosial, Lirik Lagu, Moral

Abstract

Research using satellite imagery of gravity data has been conducted in the Dampit District, Malang Regency, East Java Province. This research was conducted to identify areas vulnerable to landslides. The results of this research can serve as a basis for the government to develop effective landslide disaster mitigation policies, thereby minimizing the losses incurred. The data used is TOPEX satellite gravity data in the form of Free Air Correction data, and supported by landslide vulnerable areas data from the InaRisk satellite. The research area is 23 km x 16 km with 2 km spacing between points and 184 measurement points. Furthermore, the research area is divided into four areas: Area A1, Area A2, Area A3, and Area A4.  The residual anomaly value in the study area is between 82.7 mGal to 142.4 mGal. The residual anomalies are more variable due to the local nature of the anomalies. The correlation between the residual anomaly value and InaRisk satellite image data shows that Area A4 is the most vulnerable to landslides, especially if there is a trigger such as an earthquake.  This is because Area A4 has a low-density value, a large fault, and is the contact area between the Mandalika Formation and Wuni Formation.

Abstract

The Brigif retention pond not only serves to temporarily store rainwater for groundwater reserving but also reduces the risk of flooding in the Southern Jakarta area. Research was purposed to study two critical conditions of a dike made from clayey material from before to after water impounding stages correlating with its stability. The research will investigate pore-water pressure (u) parameter changes at any stage in both conditions. The parameter of (u) can be predicted (upre) using the laboratory consolidation or oedometer test and measured (uact) completely with hydrostatic pressure (u0) directly in the field. Actual measurements using a piezometer were also conducted on the body of the dike. The prediction analysis used the self-developed program and conventional geotechnical software. The critical peak depth of (u) was found at 3.0 to 4.0 m. The actual settlement potential values reached -0.10 to -1.42 m and matched the prediction result. Safety factor (SF) was around 2.0 to 4.0, or in stable condition. Research results found that the magnitude parameter of (u) could be influenced by groundwater flow and porosity or void ratio fluctuations. The consolidation process also would affect the physical soil pore, contributing to the change of (SF) the dike pond.
