Abstract

This study aims to determine the effect of inquiry learning model on student physics achievement in junior high school. The method used is experimental research. The sample used are; grade VII-D students as many as 27 people as control class, and level VII-G as many as 27 people as experimental class. The sample selection was done by purposive sampling technique. The data were collected by pre-test and post-test in both classes. The average pre-test in the experimental class is 28.04 and 30.11 for the control class. The average post-test score in the experimental class is 74.41 and 69.26 for the control class. The analysis result using t-test obtained t-test of 1.82 and t-table is 1.67. The value of t-test is greater than t-table at 5% and dk is 52. We conclude that there has been a significant influence of inquiry learning model on physics learning achievement.

Abstract

This research is purposed to develop caricatur based video as a teching media for physics subjeck to enrich student’ creative thiking ability.  The research was developed by using 4 D design which is well know as define, design, develop and disseminate. Collecting data is research. The researcher uses validity of  learning intruction test, quistionaire for students, and creative thiking ability test.  The research subject of this research is the VIII  grade students is the SMPN 5 plampang. The data analysis used in this study is descriptive qualititative approach. The result of vitur validation test shows that using  vitur as the physic teaching media to enrich students creative thiking ability can be categorized into  “valid” category in which the average score gained by the research subjects is 3,75 and the studen’ responses show the result in average 3,20. This result can be categorized  into high  category in using vitur as the physic teahing media to enrich  student’  creative thiking ability. The creative thiking ability test the was the distributed by  researcher to the reseach subjects show the result 67,25%. Ultimately, it can be inffered that vitur as the physics the teaching media is valid and properly used to enrich students’ creative thinking ability.

Abstract

[Title: Manufacture of Gold (Au) Capture Filters Using Chitin and Chitosan from Crab Shells]. This study aims to analyze the ratio of absorption capacity between chitin, chitosan and chitin-chitosan mixture from crab shells as a Gold catcher filter (Au). The preparation of chitin and chitosan from crab shells begins with demineralization using 1.5 M HCl, deproteination using 3.5% NaOH and deacetylation using 60% HCl. Chitosan that formed characterized and analyz ed its ability to absorb gold using AAS (Atomic Absorbsion Spectroscopy). The result of analysis using AAS showed that chitin was able to absorb 67.76%, chitin-chitosan mixture 83.57% and chitosan 87.82%. The result showed that chitosan had better absorption percentage to Gold (Au).

Abstract

The research is aimed to increase students’ creativity and studenst’ achievement at the seventh grade student of SMPN 1 Praya Timur. The type of this research is classroom actions research in wich the research was conducted in two cycles. Each cycle of the research comprising of three meetings in wich two meetings were planned to have the teaching learning activities and one meeting was specified to have the evaluations of the learning process. At the first cycle, it was found that the average score of the students is 55,10 and the classical acommplishment percentage is 37,95%. Whereas in the second cycle, it was found that the average score of the students 80 in wich the acommplishment percentage is 86,20%. The score of students’ activity at the firts cycle is 3,11 wich can be catagorized into “active” category meanwhile the score of the students’ activity at the second cycle is 3,76 whic is categorized inti “very active” category. Based on the data found in the two cycle of the study, it can be concluded that The Design Of Local Wisdom Based Comic As The Learning Media Can Increase Students’ Activity And Students’ Achievment At The Seventh Grade Students Of SMPN 1 Praya Timur.

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

[Title: Development of Flash Multimedia on Energy Materials to Improve Student Learning Motivation]. This study aims to develop flash multimedia on energy materials to improve student learning motivation. This study is a development research with ADDIE model. Flash multimedia validation involves 2 validators (media experts and media design experts). Validation results show on the aspect of the material with a score of 3.6 with the category "high validity" and the media aspect with a score of 3.4 with the category "high validity". The flash multimedia implementation (trial run) conducted on the 28 students of grade VIII in SMP Negeri 1 Lenangguar, Sumbawa. The results of the implementation showed the students 'motivation before using flash media with the average score of 2.47 with the category "less agree", and after using flash media with average score 3.41 with category "very agree". So it show an increase of student learning motivation. Thus the developement of flash media have eligibility to be used as a medium in learning physics of energy subject matter
