Abstract

The transformation of higher education in the post-pandemic era and the integration of technology in learning have significantly impacted how students interact with the academic environment. This study aims to analyze students' perceptions of the learning environment in the Geography Education Study Program, FMIPA, Universitas Negeri Gorontalo, focusing on the physical, social, and psychological dimensions. Using a quantitative approach with a descriptive survey design, the study involved 34 students as respondents selected through purposive sampling. Data were collected through a Likert-scale questionnaire to measure perceptions regarding the availability of facilities, room comfort, lecturer-student interaction, as well as motivation and emotional safety in learning. The results showed that 94.1% of respondents considered adequate learning facilities to be a key indicator of a good learning environment, highlighting the importance of the physical quality of classrooms and learning resources. Meanwhile, 47.1% of respondents viewed socioeconomic factors as highly influencing their academic performance, followed by 47.1% who considered noise levels and learning motivation as key psychological factors affecting concentration. These findings suggest that the quality of physical facilities and positive social relationships between students and lecturers are the primary factors supporting academic success, while the quietness of the learning environment and intrinsic motivation also play an essential role in creating a conducive learning ecosystem. This study contributes to the development of strategies to improve the quality of the learning environment in higher education, with practical implications for educational policy development and enhancing the academic experience for students.

Abstract

This study examines the socio-economic characteristics of labor in the coal mining and oil palm plantation sectors in Satui District, Indonesia, focusing on education level, working hours, and income. A quantitative descriptive approach was applied, with data collected from 100 respondents equally representing both sectors. Cross-tabulation and Chi-square tests were used to analyze differences in labor characteristics and their impact on income and household welfare.Findings reveal that workers in the coal mining sector generally have higher education, longer and more structured working hours, and more stable monthly income, while workers in the oil palm plantation sector are dominated by lower-educated labor with flexible working hours and variable income. Education significantly influences job position and income stability, especially in mining, and longer working hours correlate positively with income in both sectors.The study highlights that sectoral differences in education and working patterns strongly affect labor income and household economic conditions. These results provide empirical evidence to support labor policy formulation and regional economic development strategies tailored to the characteristics of each sector.

Abstract

Physical geography learning in positional astronomy topics requires strong spatial visualization and problem-solving skills; however, conventional instructional approaches often fail to adequately facilitate these needs. This study aims to analyze the effectiveness of using the Apple ecosystem in improving students’ problem-solving abilities within olympiad training on positional astronomy topics. The research employed a quantitative approach using a quasi-experimental design with a pretest–posttest control group model. The sample consisted of two groups of senior high school students in Gorontalo Province: an experimental group utilizing the Apple ecosystem and a control group receiving conventional instruction. Data were collected through problem-solving ability tests and analyzed using descriptive and inferential statistics. The findings indicate that the experimental group demonstrated a higher improvement in problem-solving skills compared to the control group. The use of the Apple ecosystem enabled visualization of solar positions, simulation of geographic coordinates, and interactive exploration of astronomical phenomena, which supported students in understanding abstract concepts. Technology-enhanced learning environments also increased learning engagement and analytical abilities in solving geography-related problems. These results suggest that structured digital technology integration can strengthen positional astronomy learning through more visual and exploratory learning experiences. This study implies that technology-based strategies can enhance olympiad training and contribute to the advancement of geography education aimed at developing higher-order thinking skills.

Abstract

Surface ocean currents are a key component of marine circulation systems and play an important role in controlling physical and ecological processes in Indonesian sea. The Southern Java sea, which are directly connected to the eastern Indian Ocean, are characterized by dynamic surface circulation influenced by large-scale oceanic processes and seasonal monsoonal forcing. This study investigates the patterns and characteristics of surface ocean currents in the Southern Java sea using global ocean reanalysis data visualized through the Earth Nullschool platform. Seasonal variability was examined using representative monthly maps corresponding to the major phases of the Asian and Australian monsoon system, including January (West Monsoon), April (first transition season), July (East Monsoon), and October (second transition season). A descriptive analytical approach was applied to identify spatial and temporal variations in surface current direction and relative intensity across both coastal and offshore areas. The analysis reveals distinct seasonal differences in surface current behavior. During the East Monsoon period, surface currents exhibit stronger intensity and a more consistent alongshore orientation, reflecting enhanced wind-driven circulation and offshore transport. In contrast, the West Monsoon and transitional seasons are marked by weaker currents and greater directional variability, particularly in nearshore sea. These findings indicate that monsoonal wind forcing, combined with large-scale Indian Ocean circulation, is the primary driver of surface current variability in the study area. This study highlights the usefulness of reanalysis-based visualization for regional-scale oceanographic assessments in areas with limited in-situ observations. The results provide baseline information that supports regional oceanographic research and offers practical insights for marine resource management, fisheries, navigation, and coastal planning in the Southern Java sea

Abstract

Introductory Physics plays a fundamental role in Geological Engineering education, as it supports the modeling of dynamic and multidimensional Earth system phenomena. Nevertheless, the course is often perceived as challenging due to the complex integration of conceptual understanding, mathematical reasoning, and multiple representations. This study aims to analyze patterns of academic achievement in Introductory Physics among Geological Engineering students and to explore potential gender-based differences. A descriptive quantitative design with an exploratory comparative approach was employed involving 24 students enrolled in the 2025/2026 academic year. Data were derived from Midterm Examination scores covering quantities and measurement, kinematics, dynamics, and work–energy. Descriptive analysis revealed a moderate level of overall achievement (63.1%) with substantial variability across students. Dynamics and Work–Energy emerged as the most challenging topics compared to quantities and measurement. These findings are associated with high intrinsic cognitive load and substantial spatial reasoning demands required in these domains. Comparative analysis indicated a statistically significant gender difference (p 0.05) with a large effect size, although the finding remains context-specific. The results underscore the need for strengthened representational scaffolding, improved conceptual integration of energy principles, and explicit spatial reasoning support in Introductory Physics curricula for geoscience education.

Abstract

Serpentinized ultramafic rocks from the Banggai Ophiolite Complex, part of the East Sulawesi Ophiolite Belt in Central Sulawesi, preserve important records of geodynamic history and fluid-rock interaction in oceanic lithosphere. This study analyzes mineral composition, serpentinization textures, and petrogenetic implications of three drill core samples from borehole NA2, Banggai Regency. The study aims to characterize lithological and serpentinization texture variations across different peridotite types. Petrographic analysis was performed on thin sections using polarizing light microscopy; rock classification used the Streckeisen ultramafic rock classification diagram. Two samples were identified as serpentinized lherzolite with olivine content 35-40%, orthopyroxene 14-15%, clinopyroxene 13-20%, and one sample as serpentinized harzburgite with very high orthopyroxene (38%) and very low clinopyroxene (5%). Three serpentinization textures were identified: mesh texture after olivine in all three samples, bastite texture after pyroxene in one lherzolite only, and cataclastic texture in the second lherzolite only. The heterogeneous texture distribution indicates local structural control on serpentinization rather than uniform pervasive alteration. Clinopyroxene depletion contrasts between lithologies reflect heterogeneous partial melting degrees within a single ophiolite mantle segment.

Abstract

Changes in rainfall are one of the factors that affect spring discharge, where during the dry season the spring discharge decreases and during the rainy season the spring discharge will increase. This study aims to (1) Determine the value of rainfall intensity in Nano Village, Boking District, South Central Timor Regency (2) Determine the distribution of rainfall in Nano Village, Boking District, South Central Timor Regency (3) Determine the relationship between changes in rainfall and drinking water resources in Nano Village, Boking District, South Central Timor Regency. The method used in this study is a quantitative method. Rainfall data for 2020–2024 was obtained from three rain posts, (1) to answer the first and second objectives, the data was analyzed using the methodPoligon Thiessen, (2) to answer the third objective, the data was analyzed using Pearson correlation..The results of the study indicate that the rainfall intensity value in Nano Village is categorized as light rain, while the distribution of rainfall in Nano Village is categorized as a monsoonal pattern. The relationship between rainfall and drinking water resources shows a positive relationship where high rainfall increases spring discharge, conversely, when rainfall decreases, groundwater supply decreases and spring discharge decreases. The conclusion of this study is that rainfall has a significant influence on the availability of drinking water resources, especially in springs. In the rainy season, increased rainfall causes increased water infiltration into the ground so that groundwater reserves increase and have an impact on increasing spring discharge. Conversely, in the dry season, low rainfall reduces the groundwater recharge process, so that spring discharge decreases.

Abstract

This study aims to identify the distribution and depth of the groundwater table in Nagari Taram by integrating resistivity data from the Schlumberger geoelectrical configuration with local geological information. Six (6) Vertical Electrical Sounding (VES) measurements were acquired across different land units to capture variations in subsurface resistivity. The resistivity data were processed through 1D inversion to interpret lithology and layer thickness, which were subsequently correlated with regional geological maps to confirm the characteristics of water‑bearing formations. The results indicate that shallow aquifers generally occur at depths of 5–20 meters with resistivity values ranging from 30 to 150 Ω·m, representing sandy layers to weathered conglomerate of the Brani Formation or young alluvial deposits. Clay and tuff layers with low to very high resistivity act as aquicludes and aquifuges, serving as barriers to groundwater flow. Variations in groundwater table depth across the sites are influenced by geomorphological conditions and surface sediment thickness. The integration of resistivity and geological data provides more accurate information for delineating shallow aquifer zones, supporting groundwater utilization for domestic and agricultural needs in Nagari Taram.
