Abstract

Research to measure the level of competency attainment of students tadris IPA Physics class A 2019 on the material of measurement, submaterial measurement’s defenition, measurement’s type and measurement’s important term in the electrical measuring instruments. This research has used a qualitative approach with descriptive research and case studies. Data collection techniques through self-application by students towards their level of competency using google serial forms. The results showed that the activeness of students in following learning is quite high. The level of readiness of students following the learning is quite good. In addition, based on the results of research can be seen that there is an improvement in material mastery competency after learning. This can be seen from the improvement of each component of competency before learning and after learning. In addition, the level of confidence in the correctness of the answers given in the pretest and posttest also increased. In addition, the research findings that students are still weak in learning competencies distinguish the level of precision and accuracy in measurement so that the material enrichment is required.

Abstract

The background of this research is that the media often used by educators is only visual, so abstract material cannot be concretized. Educators explain the material only with media in the form of whiteboards, markers, props and occasionally use power points. The learning process like this causes students to feel bored to take part in learning. The purpose of this study is to produce physics learning media using Corel Video Studio X 7 on the valid, practical and effective kinetic theory of gas material. This research is research and development (R & D). The design of the development of physics learning media using Corel Video Studio Pro X 7 on the material of Gas Kinetic Theory is using the 4D development model including: 1) define phase; 2) planning phase; and 3) develop and last stage disseminate. The instruments used in this study were validity questionnaire, practical questionnaire, and effectiveness questionnaire. The media validity test is given to 5 expert validators assessed from the material / content, media / construction, and language aspects. Practicality tests are given to educators and students, while the effectiveness test is given to students. The result of the research is that physics learning media has been produced using the valid, practical and effective Corel Video Studio Pro X 7 application.

Abstract

This research is based on low scientific literacy of students. This is due to many factors, one of which is the textbook used less able to develop the scientific literacy students. Educators are required to provide teaching materials like a module that develops scientific literacy students. This type of research is Research and Development (R & D) model 4-D models by Thiagarajan and Sammel. Instruments used are questionnaire validity and questionnaire of practicality. The result show that the characteristics of prototype are the knowledge of science, the investigative nature of science, science as a way of thinking, interaction of science and technology, and society (scientific literacy contents). At process of design, a module of digestive system based scientific literacy develop based on the as reality and good practical education. Module have been categorized as valid based on expert judgment. The learning module have been categorized as practical based on the observation, respons es of teachers and learners. In conclusion, developing a module of digestive system based scientific literacy have the relevancy and internal consistency to develop scientific literacy students.

Abstract

The building of  low voltage and cost of spin coater using DC brushless motor from the old hard disk drivers has been carried out. The spin speed of spin coater offers manual control using potensiometer. The equipment consist of the simple hardware: IC timer 555, IC shift register SIPO 74LS164, IC driver L293D, microcontroller AT889S52, LCD and then motor speed detector using a couple of photodiode and LED and using IC Schmitt trigger inverter 74LS14 as the amplifier of the sensor. The data analysis result showed that the speed up spin of  the spin coater depend on the signal frequency from multivibrator. The equipment has spin speed stability with speed range from 180 rpm until 2460 rpm. Spin coater to be tested for applications where a glass slide microscope are coated with TiO2 (Titanium Dioksida) about varies speed and show that coating result can be fliemsier with addition of speed spin the spin coater.

Abstract

Thesis is a scientific paper compiled by undergraduate students to complete their education. Many methods are used by students to obtain data or information in the preparation of this thesis. This form of activity is often used by students to obtain data by conducting field research. However, this type of research cannot always be carried out, especially in a co-19 pandemic emergency. Literature research is the right way to produce scientific work. But not all students are ready to do this library research. One reason is that there are no guidelines and examples they can guide to conducting this research. So the purpose of this writing is to provide guidelines for students and lecturers to carry out library research in the field of education.

Abstract

Student worksheets (SWS) is one of the teaching materials that can activate learners, help find the concept and make it easier to understand the subject matter. Based on the results of observation obtained information that the teacher used the teaching materials of printed books and gita but not yet the availability of teaching materials that already contain learning steps in accordance with K-13. In response to these conditions developed teaching materials in the form of  SWS Based Guided Inquiry. The purpose of this study is the production of teaching materials in the form of SWS Based Guided Inquiry on Momentum, Impulse and Collision materials  valid, practical, and effective. This study was conducted 4-D model, define, design, develop, and disseminate. SWS Validity Test obtained value 90 % with very valid category. Practicality by 6 learner was obtained by value 89.02% with very practical category, practice by 20 learner was obtained by value 86.02% with very practical category and by teacher obtained result 89.16 % with very practical category. The effectiveness obtained result with value 92.22% with very effective category. Based on research  obtained  conclusion of SWS based guided inquiry on the material of mementum, impulse and collision valid, practical and effective.
