Abstract

This research aims to develop a tool for measuring catching-throwing skills using modern, effective, and efficient sensor technology. This tool is designed to increase accuracy in measuring catch-throwing skills. This type of research uses (R&D). This research involved three experts in their field: an electrical expert, an evaluation and measurement expert, and a physicist. A total of 30 participants participated in testing in a small group of 12 people and a large group of 18 people with an age range of 15-20 years. Testing is carried out with questionnaires and direct tests. The statistical analysis used is r-correlation with the help of the SPSS application. The test results show a high alpha coefficient, confirming that this tool is consistent and reliable in collecting data. Three experts carried out practicality testing: Electrical Experts, Evaluation and Measurement Experts, and Physicists. The results show that this tool is efficient, with practicality levels of 98%, 92%, and 89%, respectively. In addition, an excellent level of effectiveness is demonstrated by expert assessment results, which reach 99%, 89%, and 85%. With this tool, researchers and teachers can evaluate object control skills more efficiently and accurately and assist in collecting more comprehensive data. Overall, this tool for measuring throwing and catching skills provides significant innovation and is expected to support research and education in measuring and developing children's motor skills.

Abstract

This study aims to determine the description of the character of students during learning with the Reading to Learn (R2L) Model in order to improve their scientific literacy skills. This learning was carried out for 3 meetings on dynamic electricity material. During the study, observations were made by two observers using an observation sheet containing the student's character. Aspects of student character observed in this study were curiosity, adaptability, social behavior, and initiative. The students observed consisted of four classes. The number of students involved was 64 students (n=64). Based on observations, the highest character that emerges from students during learning is the character of socio-cultural behavior (52.95%), while the lowest character is curiosity (44.44%).

Abstract

Monitoring level sludge pada reaktor biogas merupakan parameter kritikal untuk menjamin efisiensi produksi energi terbarukan. Namun, karakteristik sludge yang berwarna gelap dan kental menjadi hambatan bagi sensor jarak konvensional. Artikel ini menyajikan tinjauan literatur mengenai potensi implementasi sensor VL53L0X berbasis teknologi Time-of-Flight (ToF) sebagai solusi pengukuran level material semi-cair. Melalui analisis komparatif terhadap berbagai penelitian terdahulu, artikel ini mengevaluasi performa sensor ToF dalam mendeteksi objek dengan tingkat reflektivitas rendah dan interferensi cahaya lingkungan. Hasil tinjauan menunjukkan bahwa VL53L0X memiliki keunggulan pada akurasi jarak pendek dan sudut deteksi yang sempit, sehingga meminimalisir kesalahan pembacaan akibat pantulan dinding reaktor. Selain itu, artikel ini mengulas strategi linearisasi data dan penggunaan filter digital untuk mengatasi noise yang mungkin timbul akibat kondisi atmosfer di dalam tangki biogas. Kesimpulan dari kajian ini menegaskan bahwa teknologi ToF memberikan reliabilitas yang lebih tinggi dibandingkan sensor ultrasonik untuk material dengan albedo rendah. Tinjauan ini diharapkan dapat menjadi referensi teknis dalam pengembangan sistem monitoring biogas yang lebih presisi, efisien, dan berbiaya rendah bagi masyarakat luas.

Abstract

The rapid advancement of digital technology demands creative, contextual, and sustainability-aligned physics learning. However, high school physics instruction, particularly on renewable energy topics, remains largely conventional and relies on static media, limiting students’ opportunities to develop creative thinking skills. This study aimed to analyze students’ creative thinking skills and learning needs, providing an empirical foundation for the development of contextual, interactive digital physics teaching materials on renewable energy. A descriptive quantitative research design was employed, supported by qualitative data from the teachers’ interviews. The participants consisted of 266 tenth-grade students and three physics teachers from three public senior high schools in Tebo Regency, Indonesia. Data were collected using a 32-item learning-needs questionnaire, a creative thinking skills test based on fluency, flexibility, originality, and elaboration indicators, and semi-structured interviews with teachers. Quantitative data were analyzed using descriptive statistics, and qualitative data were examined through thematic analysis. The results indicate that teacher-centered practices, with limited use of interactive digital media, still dominate physics instruction. Students demonstrated a high demand for contextual, problem-based, and digital learning environments, with an overall learning needs mean score of 82.5%. However, students’ creative thinking skills were generally low, with an average score of 41.8%, particularly in fluency, flexibility, and originality, while elaboration emerged as the relatively strongest indicator. The novelty of this study lies in integrating students’ creative thinking profiles with their learning needs and classroom practices to provide an empirical basis for the instructional design. The findings indicate a significant gap between students’ learning needs and current instructional practices, underscoring the need to develop contextual, interactive digital physics teaching materials. This study contributes to physics education by offering diagnostic evidence to guide the design of digital learning innovations that foster creative thinking and sustainability-oriented understanding.
