Abstract

The research aims to detect underground rivers using 2D mapping and minimal-noise data. In this research, 2-dimensional (2D) mapping of underground rivers in karst areas was carried out using the geophysical method of very low-frequency electromagnetic waves, namely VLF-EM (Very Low Frequency Electromagnetic Method). Electromagnetic wave analysis is based on differences in object frequencies, which reflect subsurface resistivity and conductivity and are captured by the VLF-EM detector. The measurement results were analyzed using three filter equations (Moving Average, Fraser, and Karous H-Jelt) and the Graphics User Interface Matrix Laboratory (GUI-MatLab) Software. Apart from that, the use of GUI-MatLab aims to create VLF-EM data processing software that is better for 2D interpretation display and more efficient in processing (requiring data entry only once). The research area was located in the karst rock area of Gunung Kidul Regency, Yogyakarta, Indonesia, at coordinates 8.020°S and 110.36°E. The VLF-EM measurements and GUI-MatLab interpretation detected the presence of underground river flow crossing three villages in the study area (Timun Sari, Mojo Sari, and Peyuyon), with accurate results (conductive objects were easily distinguished). Therefore, based on this study, it is recommended that productive boreholes be drilled in the 3 villages where VLF measurements were taken. The productive borehole drilling is recommended in 3 villages.

Abstract

The focus of this study is the issue of reorganizing the preexisting Islamic Geometric Patterns found at the Cheng Ho Mosque via the use of computer modeling techniques. The need for computer modeling research for rearranging geometric patterns at the Cheng Ho Mosque may be attributed to many factors. The objective is to use digitization to streamline the ornamental design process. The study methodology used included the analysis of geometric forms, which were then processed and patterned using Parametric Islamic Geometric Patterns with the assistance of Grasshopper software. This study employs the Islamic octagonal archetype, similar to Chinese geometric ornamentation, using circular geometry with a radius input, as discussed in the preceding article. The inclusion of the division shape serves as a necessary limitation to facilitate the cutting of the recurring patterns. The findings indicate that the algorithmic technique is constructed using a collection of parameter inputs organized into four primary components: octagonal basis geometry, repetition procedure, partition or boundary-shaped surface, and material dimension simulation. However, it also demonstrates varying parameter inputs, posing challenges in organizing them accurately to generate the octagonal form. Visual scripts may effectively depict Islamic geometry in open systems that exhibit parametric adaptability to the fundamental principles of division. During the design processing phase, it is possible to exert control over the pattern proportions in some instances.

Abstract

This study aimed to examine innovative school leadership management in order to improve school quality. Innovation strategies in the aspects of school leadership include the promotion of the work ethic of human resources, implementation of the curriculum, learning methods and media, and school facilities and infrastructure. This research was conducted by direct field observation at SMP Muhammadiyah 2 Inovasi, Malang, thus involving in depth interview and repeated observations. This research applied qualitative approach with descriptive analysis to describe the object of study comprehensively. The results showed that school management based on innovation as a strategy to improve school quality had proven successful. In the end, the school experienced an increase in the number of enrolled students, academic and non-academic achievements. Moreover, the number of graduates who continued to a higher level was doubled.

Abstract

Energy literacy is a critical competency for cultivating awareness, responsibility, and sustainable energy practices among students. This study aims to synthesizing a framework and establishing the content validity of an instrument designed to measure Indonesian students’ energy literacy across cognitive, affective, and behavioral domains. Employing a descriptive research design, the study was conducted in two stages: framework synthesis and expert validation. The synthesized framework integrated key constructs from established energy literacy models and contextualized them within Indonesia’s socio-educational setting. The initial instrument comprised 32 cognitive test items, 20 affective statements, and 15 behavioral statements. Content validation was performed by two expert lecturers and three science teachers, who assessed the relevance, clarity, and appropriateness of each item. Results indicated that all domains achieved the “very feasible” category, demonstrating strong content validity. Following revisions based on expert feedback, 59 items were retained: 30 cognitive, 17 affective, and 12 behavioral. The validated instrument offers a comprehensive and contextually relevant tool for evaluating students’ knowledge, attitudes, and behaviors toward energy, thereby supporting the advancement of energy education and sustainable practices in Indonesia.

Abstract

Limited laboratory facilities remain a challenge in physics learning, especially for topics such as Uniform Linear Motion (GLB) and Uniformly Accelerated Linear Motion (GLBB). To address this issue, a Classroom Action Research (CAR) was conducted at SMAN 8 Yogyakarta using interactive virtual experiments based on PhET simulations. The study was carried out in two cycles involving planning, implementation, observation, and reflection. Data were collected through observation, interviews, documentation, and student worksheets (LKPD) assessment. Results showed that PhET simulations significantly improved student engagement and conceptual understanding. In class X-E1, 71.9% of students achieved a perfect score (100), and the rest scored above 62.5. Similar outcomes were found in classes X-E2 to X-E4, with most students achieving high scores. PhET proved to support contextual and interactive learning, enhancing student participation, concept mastery, and scientific process skills, while also providing meaningful learning experiences without relying on physical lab equipment.
