Abstract

This study aims to determine the improvement in students’ critical thinking skills in the IPAS topic Cerita Tentang Daerahku through the implementation of the Problem Based Learning model in Grade IV at SDN Model Mataram. This research employed Classroom Action Research using the Kurt Lewin model. The research subjects were 21 fourth-grade students of SDN Model Mataram. Data collection techniques included tests, observations, and documentation. The results indicate that the implementation of the Problem Based Learning model effectively improved students’ critical thinking skills in the Cerita Tentang Daerahku topic. This improvement is reflected in the gradual increase in students’ learning outcomes across each cycle. The average critical thinking score in Cycle II reached 81.19, while in Cycle I it was 54.28, showing an increase of 26.91 points. The post-test results also demonstrated a relatively significant difference compared to the pre-test results. These findings indicate that the Problem Based Learning model is highly effective in enhancing students’ critical thinking skills in the Cerita Tentang Daerahku topic for Grade IV students at SDN Model Mataram.

Abstract

This study aims to analyze flood susceptibility in Masni District, Manokwari Regency, West Papua Province, using a geospatial approach based on Geographic Information Systems (GIS). The study area is characterized by complex geological and geomorphological conditions and has experienced significant flood events, notably in 2020 and 2024, which affected thousands of residents and infrastructure. The research employed overlay and scoring methods by integrating six main parameters: lithology, rainfall, slope, elevation, land use, and distance from rivers. Each parameter was assigned a weight and score according to its relative influence on flood occurrence. The data utilized in this study were derived from secondary sources, including DEMNAS, RBI maps, CHIRPS rainfall data, land use imagery, and field observations. The analysis results indicate that areas composed of alluvial deposits, gentle slopes, high rainfall intensity, low elevation, residential land cover, and proximity to rivers exhibit high flood susceptibility. The resulting flood susceptibility map classifies the study area into several zones: very high, high, moderate, and low susceptibility. This research is expected to serve as a reference for spatial planning and flood disaster mitigation strategies, as well as to provide valuable information for local communities and regional authorities.

Abstract

This study aims to identify permeable zones influencing geothermal manifestations in Mount Papandayan, West Java, which holds geothermal potential. The area's geology conditions indicate that geothermal manifestations are closely related to geological structures, interpreted from ridge and valley alignments in DEM SRTM imagery. These structures form weak zones serving as pathways for geothermal fluids to reach the surface. The analysis involves interpreting lineaments from DEM SRTM data to calculate lineament density, visualized using roset diagrams and 3D models in Micromine. Results show dominant lineament orientations trending Northeast–Southwest, Northwest–Southeast, and West–East. Field validation confirms geothermal features such as fumaroles, hot springs, and altered rocks in faulted zones, marked by fault scarps and sharp river bends. Lineament density in the study area varies, categorized as low (6.1–11.6 km⁻¹), medium (11.7–16.9 km⁻¹), and high (17.0–24.0 km⁻¹). Geothermal manifestations tend to appear in high-density zones associated with fractures or faults, which function as recharge and discharge channels for geothermal fluids. The 3D model supports the link between fault presence and geothermal surface manifestations in the area.

Abstract

The research area is located in Unsongi, East Bungku District, Morowali Regency, Central Sulawesi Province, which is part of the Tokala Formation. Detailed studies of limestone in the Unsongi area have not previously been conducted. This study aims to determine the depositional environment based on microfacies analysis. The research methods included field data collection in the form of outcrop observations, lithological descriptions, and rock sampling. One rock sample was collected from each of the nine observation stations. The samples were subsequently sectioned and subjected to petrographic analysis in the laboratory. Petrographic observations were performed on nine thin sections to identify the detailed rock constituents and determine the Standard Microfacies (SMF). The results indicate that the limestone in the study area consists of crystalline limestone, rudstone, and packstone. These characteristics correspond to SMF 16, 17, and 18. The limestone was deposited in a shallow marine environment with open circulation (open marine/facies zone 7) and in shallow marine settings with restricted circulation (restricted marine/facies zone 8). These facies are characterized by massive lithology, recrystallization, the presence of foraminifera, and gastropod fragments, indicating deposition under relatively high-energy conditions.

Abstract

Seismic waves propagate from the earthquake source in all directions, with a spherical pattern moving within a three-dimensional field. Therefore, a seismograph is designed to record vibration components in both vertical and horizontal directions. Vertical vibrations are recorded on the vertical component seismogram or UD (up-down or compression-dilatation), while horizontal vibrations are recorded on the N–S (north-south) and E–W (east-west) component seismograms. These three components can be used to analyze wave propagation in three-dimensional directions. Earthquakes can be observed through the arrival of P-waves and S-waves on a seismogram. The arrival times of P-waves and S-waves are used to determine the hypocenter, which is the earthquake focus within the Earth, and the epicenter, which is the projection of the hypocenter onto the Earth’s surface. Various methods are available to determine the epicenter and hypocenter; in this study, the two- to three-station circle method and the Wadati method were used to determine the earthquake’s epicenter and hypocenter based on picking results from Seisgram2K70.

Abstract

This study aims to describe the learning interest of fifth-grade students at UPTD SDN Pamorah after the implementation of the Culturally Responsive Teaching (CRT) approach in science learning. The study was motivated by students’ limited attention and participation, as classroom activities were not yet fully connected to their cultural backgrounds and experiences. A quantitative descriptive method was applied using a survey technique. The sample consisted of 37 students who completed a 30-item Likert-scale questionnaire. Data were analyzed using percentage calculations across four indicators: enjoyment, attention, curiosity, and engagement. The results indicate that students’ overall learning interest was at a moderate level, averaging 70.42%. The curiosity indicator achieved the highest score (85.88%), while attention was the lowest (60.73%). These findings suggest that the CRT approach effectively enhances students’ learning interest, particularly their curiosity, though further efforts are needed to strengthen their focus and active participation in class

Abstract

This study aims to identify subsurface geological structures in the Gunung Talang– Bukit Kili geothermal area, West Sumatra, using GGMPlus gravity data. The data were processed through latitude, free-air, Bouguer, and terrain corrections to produce the Complete Bouguer Anomaly (CBA). Spectral analysis indicates that the depth of the regional anomaly source is in the range of 10000 m. The Tilt Derivative (TDR) and Normalized Horizontal Tilt Derivative (TDX) methods were applied to delineate geological structural boundaries. Two dimensional forward modeling along a 24 km profile with a depth of 10 km shows rock density variations between 1,800–2,500 kg/m³, representing volcanic rocks, altered sediments, and metamorphic basement rocks. The 2D forward modeling identifies a northwest–southeast trending fault zone that acts as a pathway for hydrothermal fluid migration.

Abstract

This study aims to evaluate the level of soil seismic vulnerability in Way Huwi Village, South Lampung, using the Horizontal to Vertical Spectral Ratio (HVSR) method. The analysis was conducted based on parameters including natural frequency, soil amplification factor, seismic vulnerability index, and shear-wave velocity to a depth of 30 m (V_S30). The results indicate that the subsurface conditions of the study area are heterogeneous, as reflected by the spatial variation of HVSR parameters across the area. Areas characterized by low natural frequency (f₀ < 5 Hz) and high amplification factor (A₀ > 3.5) are generally associated with thick, unconsolidated soft sediments, resulting in higher seismic vulnerability. In contrast, areas with higher V_S30 values indicate stiffer and more compact soil conditions, leading to a more stable ground response to earthquake shaking. V_S30 estimation using Particle Swarm Optimization (PSO) and Genetic Algorithm (GA) methods produced consistent results, where lower V_S30 values correlate with increased amplification factors and seismic vulnerability indices. Based on these findings, areas with high seismic vulnerability, particularly around measurement points SS2, SS10, and SS22, are recommended as priority zones for earthquake risk mitigation efforts. The results of this study are expected to serve as a basis for spatial planning, earthquake-resistant building design, and disaster risk management in Way Huwi Village.

Abstract

This study aims to describe the implementation of the Numbered Heads Together (NHT) cooperative learning model in improving students’ cooperation in Indonesian language learning for third-grade students at SDN 12 Mataram. The background of this study is the lack of optimal student cooperation during the learning process, particularly in group discussions. This research employed a qualitative approach with a descriptive method. The research subjects were the teacher and 28 third-grade students of SDN 12 Mataram in the 2024/2025 academic year. Data were collected through observation, interviews, and documentation. The results indicate that the implementation of the NHT cooperative learning model was able to create a more active, participatory, and collaborative learning environment. Students were directly involved in group discussions, able to exchange ideas, and demonstrated mutual respect and cooperation in completing tasks. The teacher acted as a facilitator who guided the discussion process and provided motivation. Overall, the application of the NHT model in Indonesian language learning has been proven to enhance cooperation among third-grade students at SDN 12 Mataram.

Abstract

This study aims to determine the various causes and impacts of child marriage in Bentenu Hamlet, Banyu Urip Village, Gerung District, West Lombok Regency. This study uses a qualitative approach with a phenomenological method with analysis as an approach to understand social phenomena from the perspective or experience of informants. The technique for determining informants in this study used a purposive sampling technique consisting of two married couples who had child marriages at the age of less than 20 years. Data collection techniques were carried out through interviews, observation, and documentation. Data analysis used the Miles and Huberman model which includes data reduction, data presentation, and drawing conclusions. Data validity was checked using source triangulation techniques, technical triangulation, and time triangulation. The results of the study indicate that there are several factors that encourage child marriage, namely individual factors, low levels of education, promiscuity, environmental conditions, as well as family economic factors and media factors. The impacts found include health aspects such as an increased risk of pregnancy and childbirth complications, economic aspects with weak financial conditions, and parenting aspects that indicate the unpreparedness of young couples in raising children. Thus, child marriage has significant negative impacts and requires attention and intervention from various parties. Keywords: Child Marriage, Causes, Impacts
