Abstract: Geological structures are frequently associated with the formation of valuable mineral deposits, often triggered by the upwelling of hydrothermal fluids through zones of weakness. This study aims to identify the geological structures in the area and delineate regions that exhibit significant mineralization potential. The Fault Fracture Density (FFD) method is employed to detect zones of weakness based on fracture density. Data collection was carried out through direct field measurements of geological structures, supported by lineament intensity data derived from the National Digital Elevation Model (DEMNAS). Geological data were processed using stereographic methods to accurately identify the active structures in the study area, while DEMNAS imagery was analyzed with PCI Geomatica 2014 and ArcGIS 10.7.1. The geological structure analysis reveals fractures indicative of strike-slip, reverse, and normal faulting. Identified fault structures include Right Normal Slip Fault, Lag Left Slip Fault, Lag Right Slip Fault, Normal Slip Fault, and Left Lag Slip Fault. Moreover, the fracture density analysis indicates that areas from the northwest to the northeast, the eastern sector, and from the south to the southwest exhibit promising potential for mineralization.Abstrak: Keberadaan struktur geologi seringkali dikaitkan dengan adanya potensi suatu endapan mineral berharga yang dipicu oleh naiknya fluida hidrotermal melalui zona-zona lemah.

Abstract: This research develops a web-based system to detect the similarity of thesis titles using the Modified Cosine Similarity method and TF-IDF weighting. This system helps students in evaluating the similarity of titles automatically, so as to avoid plagiarism and increase the originality of research. The process used includes text preprocessing (case folding, tokenizing, stopword removal, stemming), TF-IDF calculation for word weighting, and the use of Modified Cosine Similarity to measure the level of similarity between titles. The test results show that the system is able to identify the similarity of titles with a 100% recall rate, where titles with >70% similarity need to be revised, 31%-70% similarity can be clarified by adding words, and ≤30% similarity is potentially accepted as an original title. With this implementation, it is expected that students can more easily determine a thesis title that is unique and in accordance with academic standards.Abstrak: Penelitian ini mengembangkan sistem berbasis web untuk mendeteksi kemiripan judul skripsi menggunakan metode Modified Cosine Similarity dan pembobotan TF-IDF.

This study aimed to analyze the effect of the Sciedugame Mobile application on the development of students’ progressive scientific literacy in junior high school science learning. A quasi-experimental design was employed with two eighth-grade classes at SMP Negeri 56 Surabaya. The experimental class used the Sciedugame Mobile application, while the control class received conventional instruction. Data were collected through pre-test and post-test assessments, classroom observations, and student questionnaires. The results showed that the experimental group achieved higher learning gains than the control group. The average post-test score in the experimental class was 68.38, compared to 58.48 in the control class. The normalized gain (N-Gain) in the experimental group was 0.49 (moderate), while the control group scored 0.36. A t-test confirmed a significant difference between the two groups (tcount = 1.87 > ttable = 1.67 at α = 0.05). In addition, scientific literacy indicators—such as conceptual understanding, scientific process skills, and real-life application—improved more significantly in the experimental class. Observation results also indicated higher implementation quality in the experimental group (97.44%) compared to the control group (76.92%). Furthermore, student responses toward the application were overwhelmingly positive in terms of usability, content clarity, and engagement. These findings suggest that Sciedugame Mobile is a promising mobile learning tool to support progressive scientific literacy in science education.

Nutritional status is a key indicator in assessing individual health that can be determined through anthropometric measurements, particularly height and weight. This study uses a design approach that aims to design and implement a wireless system for measuring nutritional status based on Body Mass Index (BMI) using a TOF400C sensor and a Load Cell controlled by an ESP32 microcontroller. The TOF400C sensor measures height based on the Time-of-Flight principle of infrared light, while the Load Cell measures weight with the HX711 module. Data from both sensors is processed by the ESP32 to calculate BMI and categorize nutritional status according to WHO standards. Test results on 10 adult subjects showed an accuracy of 99.6% for the height measuring device and 98.3% for the weight measuring device compared to standard devices, as well as real-time results displayed on OLED and TFT screens. This system is expected to be a practical and efficient solution for digital nutritional status monitoring.

This study explores persistent misconceptions among students in physics education programs regarding the Special Theory of Relativity. Despite formal instruction, many still show fragmented understanding, often reverting to classical concepts. The aim is to identify dominant misconceptions and analyze cognitive and pedagogical causes. Using a qualitative descriptive method, 25 fifth-semester physics education students from a public university in Indonesia participated. Data were collected through a validated 20-item multiple-choice diagnostic test and semi-structured interviews. Analysis involved data reduction, narrative development, and expert triangulation. Results show frequent misconceptions in time dilation (72%), length contraction (64%), and simultaneity (60%). Students misinterpret time dilation as an absolute change, view length contraction as permanent, and fail to understand simultaneity’s relativity. Contributing factors include limited visual aids, inadequate contextual teaching, and lack of engaging media. To address this, the study suggests using digital tools like simulations and animations and adopting constructivist-based strategies. These are expected to deepen understanding and correct misconceptions. The findings aim to enhance modern physics teaching at the tertiary level.
