Abstract

Synthesis and characterization of SnO2 thin films with various types of doping materials such as aluminum, fluorine and indium have been successfully carried out. This study aims to determine the effect of various types of doping materials on the quality of thin films such as the energy band gap produced. The results showed that the higher the doping concentration, the more transparent the layer formed. In addition, the optical properties of thin films such as band gap energy are affected by the applied doping. The direct and indirect values ​​of the largest band gap energy for the percentage of 95:5% are 3.62 eV and 3.92 eV are found in the SnO2: In thin layer. Meanwhile, the lowest direct and indirect values ​​of band gap energy are in the thin layer of SnO2:(Al+F+In) for a percentage of 85:15%, namely 3.41 eV and 3.55 eV. The greater the amount of doping given, the smaller the bandgap energy produced. In addition, the more combinations of doping mixtures (aluminum, fluorine, and indium) given, the smaller the bandgap energy produced. This shows that the quality of a thin film of SnO2 produced is influenced by the amount of concentration and the type of doping used

Abstract

This study aims to determine the effectiveness of quantum physics learning tools using blended learning models to improve the critical thinking and generic science skills of students. The learning device was developed using a 4-D model which includes the stages of definition, design, development, and dissemination. Learning devices that have been declared valid then conducted a limited-scale trial in the Physics education undergraduate program at the University of Mataram, which consisted of thirty students. Analysis of increasing critical thinking and science generic skills using the n-gain (g) test. The results of the n-gain analysis for all aspects indicate that the student's critical thinking and generic science skills are in the medium and high categories. These results indicate that the use of quantum physics learning using a blended learning model is effective in improving students' critical thinking and generic science skills

Abstract

This study aims to produce problem-based physics learning tools with the help of videos that practically improve the problem solving abilities of students. The research design used is a 4D model consisting of define, design, develop and disseminate. The learning tools developed are syllabus, lesson plan, student worksheets, videos, and problem solving ability questions. The finished learning tools were then tested in a limited way in class XI MIPA 7 SMAN 1 Mataram to find out the practicality of these devices. The results showed that the device, on average, received a positive response from students and teachers. This can be seen from the responses "agree" and "strongly agree" for each component of the questionnaire given by students and teachers. Based on these data, it can be concluded that problem-based physics learning tools with the help of videos, practically improve the problem-solving abilities of students

Abstract

This study aims to the effectiveness of guided inquiry learning tools to improve understanding concepts of students on momentum and impulse materials. The learning device was developed using a 4D model consisting of four steps, namely define, design, develop and disseminate. This research was conducted at SMAN 4 Mataram in the tenth grade of MIPA 1 with a total of 20 people. The data was obtained in the form of pre-test and post-test scores. The data were analyzed using the Shapiro Wilk test and paired sample t-test at a significance level of 5%. The results of the Shapiro Wilk test show that the data are normally distributed and meet the requirements to perform a parametric test. The results of the paired sample t-test show that the t-count (24.347) is greater than the t-table (2.093). This means that there is influence of guided inquiry learning tools improves understanding concepts of students. These results indicate that the guided inquiry learning model is effective to improve understanding concepts of students on momentum and impulse materials

Abstract

This study aims to develop a quantum physics learning device with a blended learning model to improve the critical thinking and generic science skills of students. The learning device is made with a 4D development model which includes four steps, namely: define, design, develop, and disseminate. The learning tools developed to consist of semester program plans (SPP), student activity sheets (SAS), quantum physics teaching materials, instruments to measure critical thinking skills, and generic science skills of students. The validity results show that the quantum physics learning device with the blended learning model has an average value of more than 4.20. This shows that the learning tools are very feasible to improve the critical thinking and generic science skills of students.

Abstract

This activity is a collaboration carried out with SMAN 5 Mataram. This study aims to assist teachers in increasing student motivation in the physics learning process. This study was carried out through three stages, namely preparation, implementation, and reflection. The result of this activity is to create a fun learning process for students, so that students are increasingly motivated to learn to actively explore and build their knowledge. Learning that is carried out is more student-centered
