<![CDATA[Â The purpose of this research was to make learning media in a kind of Van de Graaff Generator to explain the static electric concept. The stages of this research were designing, making, and testing the effectiveness of Van de Graaff Generator. The making of Van de Graaff generator used simple devices and materials that have already available in local market, such as steel ball, electric motor, elastic belt, metal brush, and DC power supply. The testing was done qualitatively and semi qualitatively to the contents of the ball by measuring the voltage of the ground-ball. The maximum voltage ball is 942V which was produced from entry voltage on the strengthener series 6V, with the motor voltage 18V. The Van de Graaff generator can be made as learning media because can prove the existence of gathered charges at the ball.]]>

<![CDATA[ The quality of learning in the classroom is stated to be good if the learning objectives are achieved which is marked by increased student activity and learning outcomes. For that, we need alternative learning strategies that are more effective and efficient, one of which is to use the cooperative learning model type Numbered Heads Together (NHT). This study aims to improve the activity and learning outcomes of physics on wave material through the application of the NHT learning model. The research subjects were students of class XI MIPA3 of SMA Negeri 2 Tembilahan. This research is a classroom action research conducted in 2 cycles. Data collection instruments used were activity observation sheets and written tests of learning outcomes in the form of daily tests with data collection techniques in the form of observations and giving the test. The data analysis technique used is descriptive analysis to determine the extent of increased student activity and learning outcomes by applying the NHT learning model. The results of data analysis obtained an increase in student learning activities in the first cycle from 29.60% increased to 66.40% in the second cycle with a very good category. Improved learning outcomes from 12 students completed with a percentage of 48.00% in the first cycle, to 19 students who completed the second cycle with a percentage of 76.00%. Thus it can be concluded that the use of the NHT learning model can improve the activities and physics learning outcomes of students of class XI MIPA3 in SMA Negeri 2 Tembilahan on wave material.]]>

<![CDATA[ The creation of interactive learning activities can be influenced by the availability of media and learning resources as a useful tool in teaching and learning activities. The effectiveness of students' absorption of difficult and complicated learning materials can be achieved with the help of the demonstration tool as a media. The purpose of this research is to produce an earthquake demonstration tool, as a valid learning media for use in the learning process of physics in junior high schools. This development research uses the R & D method which was adapted from Nieveen & Folmer with three-phase, namely: preliminary research, development or prototyping phase, and the formative evaluation within the development stage. The evaluation of the validation of the media uses the instrument of validation of the earthquake demonstration tool with 5 indicators and the assessment of validation of the guidebook with 4 indicators. The results of the design of the media obtained the validation score for the earthquake demonstration tool with a score of 4.5 where a very valid category and the handbook obtained a validation score of 4.4 with a very valid category. Based on the results of this research, an earthquake demonstration tool had been successfully made and a guidebook for its use as a physics science learning media is valid and suitable for use in junior high schools.]]>

<![CDATA[ This research purpose to design an instrument capable to run directly bipolar transistors function as an amplifier in current, AC voltage, and as switching. This type of research is research and development, which is developing a basic application instrument for bipolar transistors. The testing to bipolar transistor elementary application instrument use measuring instrument of microampere meter, voltmeter, a generator function, and digital oscilloscope. The reached result indicates that this instrument can prove to gain the current and gain voltage of the transistor. That thing is seen from existence mean gain current 119,99 - 480. While voltage gain 1,46 - 5,29.

<![CDATA[ COVID-19 attacked Wuhan city in December 2019 where the number of cases increased rapidly, but the clinical information of infected patients was limited. One of the negative effects related is the education sector. COVID-19 also changed the learning model drastically, all learning activities were carried out online. This causes students difficulties in learning. The purpose of the research was to analyze the difficulty factors of physics education students in distance learning during the COVID-19 pandemic. This type of research is descriptive research. Data collection techniques using a questionnaire. Research subjects were 80 students from Physics education at FKIP Riau University. The results of research online learning difficulties come from two factors, namely external and internal factors. External factors include non-current internet networks and very many student assignments. Internal factors related to students' learning difficulties, students generally have difficulty communicating and discussing both fellow students and with lecturers, misconceptions occur, difficulties in summarizing the material, and eye discomfort due to cellphone and laptop radiation.]]>
