Abstract

The problem found in the field is that the e-books available in schools do not contain the 4C skills that students should have in the 21st century. In addition, the existing e-books have not shown any learning model syntax that is in accordance with the 2013 curriculum. The e-books used have not been able to involve students effectively. directly in finding the concept of learning. So, it takes a discovery learning-based e-book that is integrated with 4C skills. The purpose of this research is to produce an e-book based on discovery learning integrated 4C skills in physics learning with valid, practical, and effective categories. This type of research is research and development. The e-book development uses the ADDIE development model which consists of the analysis, design, development, implementation, and evaluation stages. Research data in the form of preliminary study data, validation, practicality, and effectiveness. The research instrument consisted of a preliminary questionnaire, validation instrument, practicality instrument, and effectiveness instrument. Data analysis was carried out using the ADDIE development method which consisted of analysis, design, development, implementation and evaluation, including aspect of knowledge, attitudes, and 4C skills; critical thinking skills, creative thinking skills, and communication skills. Based on the research conducted, it can be concluded that the physics e-book based on discovery learning integrated 4C skills is valid, practical and effective. so that it can be used to improve student learning outcomes.

Abstract

This research aims to determine the performance and design specifications of the system measuring the intensity of solar radiation using BH1750 sensor based on  internet of things with smartphone display. In agriculture, Soil fertility is closely related to maximum yield. Soil fertility and plant growth are determined by many factors, one of the most important is the intensity of solar light. The tools used in the field are still quite simple, where to measure the intensity of solar light still using a lux meter and even though the data read  from a digital lux meter cannot be seen anywhere. This measuring instrument is built using the BH1750 sensor, namely as a sensor of solar radiation intensity, NodeMCU ESP8266 as a microcontroller programmed using the Arduino IDE programming language to access the internet network so that it can be sent to the Thingspeak server, and data from Thingspeak is displayed on an Android smartphone using the APP Inventor application, and the data can be displayed. displayed on the Thingspeak server, and also can be stored in memory Micro SD. Based on the results of the development of a measuring instrument for the intensity of solar radiation, it is obtained Data where the highest solar intensity occurs on average between 02.55 – 03.38 UTC ± 0 and between 04.00 – 06.20 UTC ± 0, Each plants has a different need for solar intesity  for photosynthesis because the more solar that is sufficient on the plant, so the plants it will become optimal growth.

Abstract

Research on the degradation of methyl orange has been carried out using the photosonolysis method with the help of a TiO₂ catalyst. This study aims to determine how the effect of adding catalyst mass to the degradation of methyl orange and to determine the optimum time to degrade methyl orange. The variation of the mass of the catalyst used to degrade the methyl orange dye is from 0 grams to 0.25 grams, while the time variation is in the range of 30 minutes to 150 minutes with a 30 minute interval. The results of the measurement of the maximum wavelength and the color of methyl orange using a UV-Vis spectrophotometer were 462.8 nm with an absorbance value of 0.772. In the variation of the catalyst mass, the maximum mass obtained at 0.1 grams of TiO₂ catalyst with %D obtained was 23.46% while for the variation of the degradation time the optimum time was obtained at 120 minutes with the %D result of 32.04%. In this study, the presence of hydroxyl radicals produced during the photosynthesis process plays an important role in the process of degrading methyl orange.

Abstract

The PBL model has relevance and potential in developing 21st-century skills. This study uses the Systematic Literature Review method to identify PBL research trends in science courses at universities. A literature search using the app Publish or Perish with the Scopus database and data from journals indexed by SINTA (Science and Technology Index) in the last 10 years, from 2012 to 2021. In this study, there are 32 articles about PBL research in science lectures, including physics, chemistry, biology, and natural science.  The trend seen is a rise in publications addressing various facets of critical thinking abilities. Among research publications, quantitative research is the most common type. Quasi-Experimental designs are most often chosen by researchers, while RD designs are still little used. Chemistry is a subject that is most often chosen as a research subject. Meanwhile, the test is the most commonly used instrument for collecting data on 21st-century student skills

Abstract

Physics has an important role in development and technology. Physics is concerned with experiment. From the results of research that has been carried out, it is known that there is no linear motion of  kinematics experiment with speed control and the use of an inclined plane for the sliding plane of the linear motion experiment. The limitation of the instrument in displaying physical measurement quantities is one of the reasons. To overcome this limitation, a modeling tool assisted by a remote control toy car and analyze it using tracker software  is created. The purpose of this study is to determine the performance specifications of the modeling tool for linear motion experiments assisted by a remote control toy car, determine the value of the accuracy and precision of the modeling tool, and also determine the correlation of physical quantities in linear motion experiments. Based on the results of data analysis using tracker software, there are three results can be explained. First, the performance specifications of linear motion experimental modeling tool with the length of the glide plane being 2 m and a width of 30 cm. The use of a dc motor, bluetooth module using an android connected to the HC-05. Second, the accuracy of the measurement of time and speed in the LMCV experiment was 98.4% and 97.2%. The accuracy values for the measurement of acceleration and velocity in the LMCA experiment were 95.53% and 95.5%. Third, in LMCV the correlation between position and time is in the form of a linear line, the correlation between velocity and time is in the form of a straight line with a constant value

Abstract

The purpose of this study was to determine Science Process Skills (KPS) by applying the learning model to class VII materials on Temperature and Heat at Dr. Private Middle School. Wahidin Sudirohusodo for the 2022/2023 Academic Year conducted this research against the background of the low Science Process Skills (KPS) in Science for the last five years to 2021/2022, so that student learning outcomes were unsatisfactory. This was because students considered Science to be a difficult subject, especially Science Physics because it is necessary to use learning methods and models that can improve students' science process skills. This study used the classroom action research (PTK) method whose model was developed by Kemmis and McTaggart. Data collection techniques in this study used pretest and posttest test instruments with a population of 210 students spread across 7 parallel classes and one class was taken with 30 students as a sample. Data analysis using descriptive analysis was carried out by interactive analysis. The use of the inquiry training learning model has a good influence on improving science process skills. The research was conducted in pre-cycle and two cycles. In the pre-cycle with the pretest with a completeness score of only 16.67%, in the first cycle the completeness was 76.67%. Then the learning improvement was carried out again in cycle II, with inquiry training, completeness 83.33% So there was an increase in students' Science Process Skills.
