Abstract

This is quasy experiments research aimed to find out the differences of physics study result through problem based learning model with comic physics assist and conventional learning on students of grade VIII SMPN 1 Labuapi in academic year 2013/2014. This research used design of Posttest Only Control Group Design, while the sampling technique used is cluster and purposive sampling. Population of this research is students SMPN 1 Labuapi of grade VIII while the sampling are the students of grade VIII B as experiment group and the students of grade VIII C as control group. The data of this study is analyzed by using two tail t-test of polled varians, those are 6,25 for  thint and 2,0294 for ttable with degree of freedom 36 and significantce 5%. This result ( thint > ttable ) H0 will be rejected and Ha will be accepted which indicates that the physics study result through problem based learning model with comic assist is different from that through conventional learning on  students of grade VIII SMPN 1 Labuapi in academic year 2013/2014.

Abstract

This research is a quasy experiment which aimed to finding out the effect of contextual learning model implementation assisted by media flash on the understanding concept of physics in SMPN 1 Labuapi. The population is all class VIII which filled by 117 students, while the sample of this research is class VIII B with 23 students as experiment group and grade VIII C with 23 students as control group. The sampling technique used is purposive sampling. The research design used is nonequivalent control group design. The hypothesis is tested by t-test separated varians. Based on by calculation hypothesis testing obtained that there is a difference of understanding concept of physics between experiment group which is given treatment with contextual learning model assisted by media flash and control group which is given treatment as convensional learning. The mean of the posttest for experiment group is greater than control group, so it can be obtained that contextual learning model assisted by media flash given positive result for understanding concept of physics in grade VIII SMPN 1 Labuapi. N-gain test given that for all of sub materi of light showed that the increasing of understanding concept of physics of class experiment is higher than control class, so it can be obtained that the increasing of understanding concept of physics of experiment group is higher than control group.

Abstract

The present study aims at expressing and partially purifying PtpB in active form. To achieve this, Mtb PtpB gene has been cloned into pET30a vector and overexpressed in Escherichia coli BL 21(DE3) under IPTG induction in the form of an inclusion body. Following resolubilization by urea and dialysis, the resulted PtpB has been shown to be active against para-Nitrophenyl phosphate. It is concluded that the resulted PtpB has had been recovered from inclusion body to give the active form of the enzyme, and thus the success in overexpressing PtpB provides the required material to investigate the biochemical properties of the pathogen virulence factor further.

Abstract

Tujuan dari kegiatan pengabdian kepada masyarakat yang dilakukan oleh tim pengabdian yaitu membimbing guru-guru dalam membuat media permainan edukatif yang meliputi program aplikasi findthatword dan eclipse pada Guru-Guru MIN 3 Cakranegara. Metode yang digunakan adalah metode ceramah, pembimbingan penyusunan media permainan edukatif, diskusi dan Tanya jawab. Hasil pengabdian para guru dapat mendesain sendiri media permainan edukatif yang meliputi media permainan acak kata dan TTS sesuai dengan materi pelajaran yang  diajarkan masing-masing, para guru sangat antusias dan semangat mengikuti kegiatan pengabdian ini karena bagi mereka kegiatan ini sangat bermanfaat, membantu para guru dalam mempersiapkan proses pembelajaran dan merupakan salah satu alternative media permaianan yang efektif sehingga proses  pembelajaran berjalan optimal dan menyenangkan bagi peserta didik.Training of Educative Game Media Development in MIN 3 Teachers CakranegaraAbstract: The purpose of the community service activities carried out by the dedication team is to guide teachers in making educational media games that include findthatword and eclipse application programs for MIN 3 Cakranegara Teachers. The method used is the lecture method, guiding the preparation of educational media games, discussions and question and answer. The results of the dedication of the teachers can design their own educational media games which include random word and TTS game media in accordance with the subject matter taught respectively, the teachers are very enthusiastic and enthusiastic in participating in this service because for them this activity is very useful, helping the teachers in preparing the learning process and is an alternative game media that is effective so that the learning process is optimal and enjoyable for students.
