Abstract

The current era of globalization has succeeded in creating various problems and challenges of human life. The ability to solve problems and challenges of life is very necessary. The place for education, especially science, is the main key so that citizens are able to live their lives well. The phenomenon of the low mastery of integrated science content of students at the basic education level cannot be separated from the dimensions of their literacy attitude. These dimensions include the application of science, knowledge of science, the process of science, and patterns of behavior towards science. The aim of this study was to describe the scientific literacy skills of students in learning with factual texts. The type of research used is descriptive qualitative research. A total of 40 students were used as sources of information to view and obtain a literacy competency profile in science learning. Data were collected through observation and tests through a number of questions to obtain information on the dimensions of students' literacy attitudes. The research finding is that there is an increase in learning progress based on the results of the pretest and posttest with a difference of 15.8 points for the overall PISA competency aspect. The competence aspect of explaining scientific phenomena obtained the lowest average result, while the competence aspect of evaluating and interpreting the data obtained a higher average result. Thus, it can be concluded that the implementation of science learning in schools should be more meaningful for students so that they are able to have higher literacy skills, especially scientific literacy. This can be achieved by applying holistic and integrative learning in science learning

Abstract

The background of this research is the lack of variation in teaching materials and the reliance on traditional teaching methods, which affects the low causality thinking skills of students in schools. The aim of this research is to create digital teaching materials in the form of a scrapbook that can serve as a tool to improve students' causality thinking skills in history learning at SMA N 1 Banuhampu. This research uses a mixed-method approach with data collection techniques through observation, interviews, and reinforced by administering simple tests to students. In this way, the researcher can analyze the needs in developing digital scrapbook teaching materials. Based on these findings, the researcher found that there is a lack of variety in teaching materials, and many teachers and students still use conventional teaching materials during learning. Considering the problems that have been identified, the researcher plans to develop teaching materials utilizing technology. The use of technology will help create diverse learning styles that can be adapted and serve as support in enhancing students' causal thinking skills. The digital scrapbook teaching materials developed by the researcher in this study provide an opportunity for students to better understand the learning material, thereby improving their causal thinking skills in history learning.

Abstract

The 1-phase controlled full-wave rectifier is one of the main components in power electronics technology that functions to convert alternating voltage (AC) into direct voltage (DC). This circuit is used in various applications, such as battery charging systems and DC motors in industry. Controlled rectifiers use a Silicon Controlled Rectifier (SCR). The use of SCRs in controlled rectifiers provides the advantage of more precise current control. The controlled rectifier uses a Silicon Controlled Rectifier (SCR), which is controlled with a microcontroller through an SCR driver. The SCR driver serves for isolation so that the converter circuit does not damage the microcontroller due to current surges. This circuit also requires a zero crossing detector to determine the intersection of point 0 on the AC wave. This research aims to design and build a 1-phase full wave rectifier system using SCR as the main controlling component. With a deep understanding of SCR characteristics, it is hoped that this research can contribute to the development of modern power supply technology that is more efficient and can be controlled with precision.
