Abstract

Thie aims of this research was to measure the influence of student pocket book usage by using evaluation technique on cheerful puzzle media towards activity and the learning outcomes of physic, on vibration and wave. The research implied on Quasi Experiment with the design of Pretest-Posttest Control Group Design. The research sample taken by purposive sampling technique. The research instrument used on the collecting data process is observation sheet and multiple choice test. Based on the average of student activity on the experiment class was higher than class control. Based on the data, on the experiment class found that the average of the first meeting was 73,33%, and on the second meeting was found that 81,33%. Which categorized as very good and excellent, meanwhile on the control class for the first meeting was found the average of student activity was 64% and the second meeting shown that 57,3% which categorized enough and good enough. The average of the result of study on experiment class was 52,5 and for the class control was 53,8. In tears of posttest data resulted, the average of experiment class was 70,67, and the control class was 65,17. Based on the result of t-test data, posttest resulted tcalculate > ttable (14,05>2,03) with  = 5%, and found that alternative hypothesis (Ha) accepted. Thus it can be conclude that there is influence of using pocket book for student with the evaluation technique on cheerful puzzle media towards activity and learning outcomes study on the topic vibration and wave at  SMP 11 Mataram.

Abstract

This research aims to make prototype battery from star fruit as alternative energy. In everyday life electrical energy used comes from fossils that will be used up in a period of time. Therefore, it takes an alternative energy that can reduce the use of non-renewable energy. We utilize star fruit vegetable as an alternative energy used as a replacement battery, where the battery can be used as energy. Battery of star fruit has a power of 1 Volt and almost equivalent to the battery in the market that is 1.5 V voltages.

Abstract

The purpose of this study was to determine the effect of cooperative learning model of group investigation type against scince generic skills of students. This research was a quasi-experimental. The population in the study was a grade VIII MTS Nurul Falah NW Lajut with 36 students. Sampling was derived by random sampling where the 16 students of VIII A as on experimental class and VIII B as a control class with 20 students.Based on pretest data analysis, obtained an average value of 31,25 experimental class and control class was 42,2.Posttest analysis showed an average grade of 65,75 experimental and control class was 61,6.  The data analysis technique was t-test. It show t- test= 5,80 and t-table = 1,67. Because of  t-count is greater than the  t- table, it can be concluded that there were the effect of cooperative learning model of group investigation generic against science skills of student.

Abstract

Based on the observations and interviews of some physics teachers, it was found that the teacher felt that he had tried to improve the learning techniques in the classroom. But the activity and achievement of student learning not yet according to expected result. The learning pattern applied is teacher-center learning. Therefore, this is very inconsistent with the characteristics of science learning. PhET (Physics Education Technology) application program is one of the learning tools that requires students to take an active role during the learning process. This study is a classroom action research conducted in two cycles to determine the effectiveness of learning. Each cycle takes place in two sessions. Each cycle consists of the stages of planning, implementation of action, observation, evaluation, and reflection. The subject of the research is the students of class IX.1 SMPN 2 Lingsar. The results of the evaluation of cycles I and II showed a significant increase. The average score of student learning activity increased from 7.95 to 11.39 (medium to high category) and the average student evaluation score increased from 62.5 to 76.65. We concluded that the PhET application program is effective for increasing activity and student learning outcomes.

Abstract

Physics is one of the subjects taunght in SMPN 4 Praya Tengah. The  Instructional media which used is still relatively conventional with teaching materials such as text books. This study used a learning media of animation software in a virtual learning environment to enhance the problem solving ability of students. This study was a quasi-eksperimental study. The study also included into the study of population, because the entrie student population used in the study. The data analysis technigue which used was the t-test. The results obtained are tcaculate = 2,87 and ttable = 1,72. because   tcaculate its count greater than ttable it can be concluded that there  are impact of using the virtual media laboratory of physics to student’s problem-solving abilites.

Abstract

It has been done plating a copper with process electroplating technique using a solution of nickel and chrome. The purpose of this study to find the best strength of the layer with the optimal flow. The strength of the material in the test with the impact test on a sample of coated copper at different work flows (1A, 1.5 A, 2.0 A, and 2.5 A). The results of the impact energy impact test obtained for each flow which is 2.1566 J / mm2; 2.3017 J / mm2; 1.9319 J / mm2; 1.9205 J / mm2. From the analysis concluded layer with high impact strength at an operating current of 1.5 A
