Abstract

The performance of heterojunction silicon solar cells strongly depends on the quality of the Transparent Conductive Oxide (TCO) layer, particularly Indium Tin Oxide (ITO), which governs both lateral charge transport and optical coupling. Despite its industrial relevance, achieving low-resistivity and high transmittance ITO at low thermal budgets remains a manufacturing challenge. This study aims to identify and optimize the key pulsed DC magnetron sputtering parameters that govern the structural, electrical, and optical properties of ultra-thin ITO films suitable for heterojunction applications. A systematic experimental approach was implemented by varying discharge power, oxygen partial pressure, deposition temperature, and post-deposition annealing conditions using an inline industrial sputtering system. The results show that moderate discharge power, controlled oxygen incorporation, and substrate temperatures around 180 ◦C significantly enhance film densification and electron transport. Under the optimized parameter set, the ITO films achieved low resistivity in the range of (4.6–5)×10−4 Ω·cm and visible-light transmittance above 90%, while annealing at 160 ◦C further reduced defect density and stabilized electrical per- formance. These findings demonstrate that high-quality ITO can be produced within the thermal constraints of heterojunction silicon technologies and provide a robust foundation for integration into automated or AI-assisted sputtering control frameworks. Overall, this work supports the development of scalable, energy-efficient, and industrially viable fabrication routes for next-generation photovoltaic devices.

Abstract

This research is motivated by the lack of development of learning video media for Contextual Teaching and Learning (CTL) models that explain biodiversity material at SMA N 20 Merangin. The learning method is conventional, the media used is Infocus, and the learning resources used are textbooks. The shortcomings of learning methods, media, and learning resources found at SMA N 20 Merangin are still conventional, resulting in students playing a less active role and becoming bored during learning, especially when learning about biodiversity material. These points consider the creation of items within the framework of learning video media for Relevant Contextual Teaching and Learning (CTL) models that are substantial and commonsense for lesson X SMA. This type of inquiry is improvement research using the 4D model. The investigative methods utilized in this investigation are legitimacy surveys and common sense surveys for instructors and students. Five validators approved this investigation to test the legitimacy of learning recordings based on CTL models, specifically four speakers from Merangin College and one science educator from SMA N 20 Merangin. Relevant CTL demonstrate learning video media items, within the perspective of substance possibility, with a 91% (Exceptionally Substantial) rating, introduction midpoints of 91% (Exceptionally Valid), media illustrations midpoints of 95% (Exceptionally Substantial), and an overall number of perspectives of 92% (Very Valid). The learning video item based on the CTL show is additionally complemented by the Learner Worksheet (LKPD). Within the fabric angle, the normal score is 100% (Exceptionally Substantial), the standard dialect score is 87% (Exceptionally Substantial), and the overall number of angles is 93% (Exceptionally Substantial). The common sense test of learning video media based on the Relevant CTL demonstrates an average of 3.91 (Exceptionally Down to Earth) from teachers and an average of 3.31 (Common Sense) from students. Based on the considerations delivered, items are presented in the form of learning video media, based on the Relevant CTL model of biodiversity fabric, which is substantial and down-to-earth for lesson X SMA.

Abstract

This research is motivated by the implementation of science learning for eighth-grade students at MTs Mohamad Hekal, which is still dominated by a conventional, teacher-centered approach. The teacher acts as the sole source of information, while students tend to be passive, simply receiving material without engaging in critical thinking, exploration, or problem-solving. This impacts learning outcomes, which generally do not meet the school's Minimum Completion (KKM) score. This study aims to improve science learning outcomes for eighth-grade students at MTs Mohamad Hekal. The type of research used is Classroom Action Research. The subjects were 28 eighth-grade students at MTs Mohamad Hekal. The research instruments used were observation sheets of teacher and student activities, as well as assessment test questions. The results showed an increase in teacher and student activity. Teacher activity in Cycle I, Meeting 1, was 80%, Meeting 2, 90%, and in Cycle II, Meetings 1 and 2, increased to 100%. The increase in teacher activity from cycle I to cycle 2 was 15%. Student activity in Learning Activity Meeting 1 was 80%, and in Cycle I, Meeting 2 increased to 85%. Then in cycle II, it increased to meeting one by 90% and in meeting 2 to 96%. There was a 10.5% increase in student learning activity. Student learning outcomes, with an average value of 75.18 in Cycle I and 80.26 in Cycle II, showed a 5.08-point increase. From the study's results, it was concluded that the application of the Project-Based Learning Model (PjBL) in science subjects can improve teacher activity, student activity, and learning outcomes for class VIII students at MTs Mohamad Hekal.

Abstract

The teaching of physics and biology as part of science education in high school should be linked to real-world phenomena and local culture so that students can understand scientific concepts in context. One aspect of Minangkabau culture that has the potential to serve as a learning resource in high school is Silek Kumango, a style of silek originating from Nagari Kumango, Tanah Datar, West Sumatra. This study aims to examine Minangkabau Silek Kumango through an ethoscience approach by identifying the physics and biology concepts present in its movements as a potential learning resource for high school students. The method used is a descriptive qualitative approach based on a literature review. Data were collected from scientific articles, documents, and previous research findings regarding Silek Kumango, ethnoscience, and culture-based science education. The findings indicate that Silek Kumango incorporates physics concepts such as motion, force, equilibrium, impulse, momentum, work, energy, torque, center of mass, and friction. From a biological perspective, Silek Kumango relates to the human musculoskeletal system, muscle function, joints, neural coordination, body balance, reflex responses, respiration, and physical fitness. The integration of Silek Kumango into high school physics and biology instruction can serve as a contextual learning resource for topics such as motion, energy, the human musculoskeletal system, the nervous system, the respiratory system, and the circulatory system. This study demonstrates that local culture functions not only as a cultural heritage but also as a bridge between community knowledge and scientific knowledge in schools.

Abstract

This study aims to evaluate the impact of problem-based learning models on students' metacognition in science learning. This type of research is a meta-analysis using the PRISMA 2020 method. Articles from Scopus and Google Scholar databases were collected using Publish or Perish (PoP) software. From 8 articles that met the inclusion criteria, a total of 20 data were obtained to be processed in the meta-analysis. Data analysis was used with JASP software.The results of this metaanalysis research show that problem-based learning model provides moderate effectiveness on students' metacognition in science learning (r RE = 0.67; SE = 0.16; z = 4.24; p < 0.001). This shows that problem-based learning model can improve students' metacognition in science learning. Through PBL, students become more aware of their cognitive strategies and learn to organise them more effectively. Incorporating PBL into the science curriculum can significantly improve students' metacognition, leading to more independent and effective students. Therefore, widely adopting PBL in science education is recommended to achieve better learning outcomes
