Abstract

This study analyzes the effectiveness of a training program on lecture design in enhancing the pedagogical competence of lecturers at STAI Yogyakarta. Adopting a qualitative approach with a case study design, the research explores how the program successfully transforms the teaching paradigm from a conventional, teacher-centered model to an active, student-centered learning philosophy. Primary data were collected through in-depth observations and documentation involving 25 participating lecturers from STAI Yogyakarta. The data analysis utilizes content analysis and is validated through data triangulation to ensure the credibility of the findings. The results show that the training effectively shifted the lecturers' roles from being sole knowledge providers to being facilitators and mentors. A key finding is the adoption of innovative instruments like Concept Maps, which help lecturers logically organize complex subjects and integrate Islamic values into their curriculum. Furthermore, the implementation of authentic assessment ensures that learning outcomes are measured not only by memorization but also by analytical and practical skills, aligning with national educational standards. This training successfully fosters holistic competencies—covering cognitive, affective, and psychomotor domains—and provides a valuable model for other Islamic higher education institutions.

Abstract

The increasing energy demand in Indonesia encourages the exploration of alternative energy sources, including geothermal energy. Bondowoso Regency, particularly the Blawan area, holds significant geothermal potential that remains underutilized. This study analyzes the relationship between Land Surface Temperature (LST), Normalized Difference Vegetation Index (NDVI), and Land Use Land Cover (LULC) using Landsat 8 imagery processed through Google Earth Engine. Spatial data of LST, NDVI, and LULC were extracted, visualized, and interpreted to identify geothermal manifestation areas. The results show that geothermal manifestations are indicated by high LST values (above 35°C), low NDVI values (sparse vegetation), and specific land use patterns, especially in the northeastern part of Bondowoso. The integration of LST, NDVI, and LULC enables more accurate identification of geothermal potential. The study concludes that remote sensing-based analysis is effective for detecting geothermal manifestations and supports more optimal geothermal resource mapping, exploration, and management, contributing to the sustainable development of renewable energy in the region.

Abstract

An earthquake that occurred on December 30, 2024 in Gresik Regency, located at 7.05° S and 112.62° E with a focal depth of 14 km and magnitude M3.3, was a shallow earthquake felt with an intensity of II–III MMI. This study aims to analyze the earthquake shaking intensity map (Shakemap), determine the earthquake source mechanism, and perform earthquake scenario modeling using the maximum magnitude based on the Indonesian Earthquake Source and Hazard Map (PUSGEN). Shakemap analysis was carried out using the BMKG Shakemap server based on accelerograph network data. Fault mechanism analysis was performed using focal mechanism software with P-wave polarity input obtained from waveform signal picking using SeisGram2K software. Meanwhile, the Shakemap scenario was generated using the ShakeMap application available at the Pasuruan Geophysical Station. The results show that the distribution of Peak Ground Acceleration (PGA) and shaking intensity is influenced not only by the distance from the epicenter but also by local geological conditions that contribute to ground-motion amplification. Source mechanism analysis indicates that the Gresik earthquake was dominated by a strike-slip faulting mechanism with a weak oblique component, interpreted as sinistral strike-slip motion along the RMKS–Tuban 3 fault zone. Scenario earthquake modeling with a magnitude of M 6.2 indicates that Gresik Regency has the potential to experience strong ground shaking with maximum intensities reaching VI–VII MMI, while surrounding areas such as Surabaya City, eastern Lamongan Regency, and western Bangkalan Regency may experience intensities up to VI MMI. These findings indicate that although the Gresik earthquake had a relatively small magnitude, the potential earthquake impact in Gresik and surrounding areas could become significant if a maximum-magnitude earthquake occurs, therefore, this study provides important information for earthquake disaster mitigation efforts.

Abstract

The southern Java subduction zone is one of the major tsunami hazard sources in Indonesia due to its potential to generate large megathrust earthquakes. This study evaluates tsunami hazards from a Mw 8.7 megathrust earthquake worst-case scenario using numerical modeling with COMCOT v1.7. A five-layer nested grid system is applied to simulate tsunami generation, propagation, and inundation from the Indian Ocean to the Pancer - Puger coast, Jember Regency, Indonesia. Earthquake source parameters are defined using the Wells and Coppersmith empirical relationships, while initial seafloor deformation is calculated using the Okada elastic dislocation model. Tsunami wave dynamics are analyzed using Virtual Tsunami Gauges (VTGs). The results indicate that Puger Kulon and Mojosari villages experience the most severe impacts, with large wave amplitudes, strong currents, and inundation exceeding 20 m depths. Tsunami arrival time is about 21 to 27 minutes, providing a very limited evacuation window. The ETH (Estimated Tsunami Height) and ETA (Estimated Time of Arrival) maps show that low-lying, open coastal plains act as primary pathways for tsunami penetration. These findings emphasize the high vulnerability of the Pancer coast - Puger and the need for risk-based mitigation, improved evacuation planning, and strengthened local early warning systems.

Abstract

This study the relationship between the age of sugarcane plants (Saccharum officinarum L.), vegetation indices, and sugar content using Sentinel-2 satellite imagery in Jember Regency. Vegetation indices such as NDVI, GNDVI, NDRE, and NDII were used to monitor the physiological condition of the plants, while sugar content was measured using a refractometer on the upper, middle, and lower sections of the sugarcane stalks. The results indicate that the highest sugar content was found in the lower stalk section, as this area serves as the primary storage site for sucrose. There is relationship that increasing plant age correlates with changes in vegetation index patterns, peaking during the maximum vegetative phase. These findings offer significant insights into technology-based sugarcane land management, supporting the optimization of harvest timing, irrigation, and fertilization.
