The purpose of this research is to find out the problem-solving physics by using media-based videoscribe learning. Learning with the help of a video will make students more interactive and active because students can understand the concept of abstract and solve the problem of physics related to daily life. The method used in this research was the quasi-experimental method with the research design of The Randomized Post-Test Only Control Group Design, which involved 30 students as samples in Physics Education of Indraprasta PGRI University.The technique analysis of the research using the T-test. The results showed that by using learning media videoscribe could improve the ability of problem-solving physics. We found significant positive effects of the use of videoscribe in conveying physics lessons With the help of video scribe, learning is more efficient in physics learning. The students understand abstract physics material and are able to activate students in learning. These findings are consistent with studies on the improve of the student’s problem-sloving ability on physics learning.

To help realize UNP's vision towards a research-based university, awareness of Educators is needed to be active in providing innovation in classroom learning such as transforming conventional learning into research-based learning. This aim of this study was to analyze the implementation of research-based learning in Integrated Science courses Class VII in an effort to improve the ability to think critically and creatively. The study used the Quasi Experimental Research method with the design of the Pretest-posttest Control Group Design. The study was conducted in two sample classes obtained from cluster random sampling techniques by providing research-based learning treatment to the experimental class and ordinary learning to the control class. The research data was pre-test and post-test instrument, student response questionnaire and observation sheet during the learning process. With the implementation of research-based learning, the ability to think critically and creatively students of Physics Education FMIPA UNP was expected to be able to increase.

This research aims to discover the effect of scaffolding causalitic thinking approach with preliminary task toward impulse and momentum student’s problem solving ability (PSA) at X grade. The type of this study is quasi experimental research with post-test only control group design. The research population is all student’s of X MIA SMAN 8 Mataram with 33 chosen students from X MIA 1 as experimental class and 32 chosen students from X MIA 3 as control class as the sample by using cluster random sampling. Based on the research finding, it is found that the average score of problem solving ability in experimental class is 65, while the average score of PSA in control class is 53. The PSA data of two classes were normal distributed. According to the result of homogeneity test, it was obtained that both are homogen. The PSA data were analyzed with t-test polled varians. The data analysis showed that tcount was 3,3690 and ttable with significant rate (5%) was 1,9987 which means tcount >ttable.Based on that fact, it can be concluded that there is an effect of scaffolding causalitic-thinking approach with preliminary tasks toward PSA impulse and momentum students at X grade.

Aedes aegypti is the main vector which transmits Dengue virus as causing agent of Dengue Haemmorhagic Fever (DHF). Chemical control of Ae. aegypti have an impact on the environment and humans, also burden a high cost. One of the efforts to reduce the negative impact of synthetic insecticide, which is to find out alternative natural insecticide from plant-based insecticides. The purpose of this research is to determine the killing power of the rhizome bangle extract to Ae. aegypti larvae. This research was a quasi-experimental design with post test only control group design. The concentration of extract rhizome bangle used were 0%; 0.125%; 0.25%; 0.5%; 0.75% and 1%. The mosquito sample used in this study were instar III of Ae. aegypti larvae as many as 600 larvae. Data analysis used univariate and bivariate (probit and Kruskal Wallis test). The results showed that there was an effect of the concentration of extract rhizome bangle against the mortality of Ae. aegypti larvae with p=0,002 (p<0,05). Extract rhizome bangle effectively killed Ae. aegypti larvae with LC50 and LC90 were 0.148 % and 0.338 %, with the most effective concentration is 1%. Based on this research, extract rhizome bangle has a larvicidal effect on Ae. aegypti, so it can be used as an alternative method to minimize the usage of chemical larvicides that easily applied by the community.

Abstract The GI-GI learning model is a combination of the Group Investigation and the Guided Inquiry model. The research aimed to examine the effect of the GI-GI learning model on collaboration and students’ science process skills. The type of research carried out was Quasi-Experimental and used a post-test only control group design and purposive sampling covering four high schools in the Besuki Residency, two classes as the experimental class and the control class. The research instrument used tests, observations, and documentation. The results showed a significant effect of the GI-GI learning model on collaboration and students’ science process skills. This research implies that the GI-GI learning model can condition students to research in groups to interact actively with friends and educators to exchange opinions, knowledge, or experiences, find and solve problems, and hypothesize through investigation, exploration, and discussion outside or inside in class.

The objective of the study is to identify: (1) the influence of Tabata training from the perspective of “Good” category in preliminary VO2Max level; (2) the influence of Tabata training from the perspective of “Moderate” category in preliminary VO2Max level; (3) the influence of Tabata training from the perspective of “Poor” category in preliminary VO2Max level; and (4) the appropriate preliminary VO2Max level that should be assigned on the Tabata training method. Looking at the objective of the study, the nature of the study is indeed quantitative while the method that had been implemented is the quasi-experimental research with non-equivalent (pre-test and post-test) control group design. Within the conduct of the study, the number of the sample that had been involved was 60 respondents and these samples were gathered by means of quota sampling. Then, the data that had been gathered were analysed by using the paired sample t-test in order to test the hypotheses that had been assigned. The results of the study show that the Tabata training method is appropriate to be assigned in the “Moderate” category of preliminary VO2Max level. Departing from the conclusion, it might be implied that the study might be conducted further by adding the number of the sample and by adding the different type of samples.

This study was aimed at determining the differences in the dimensions of cognitive processes between groups of students who are taught with project-based trying learning activities and groups of students who are taught with conventional learning activities. This research is a quasi-experimental study with a post-test only control group design. The population of this study was the fifth-grade students of the 2016/2017 academic year in the Curriculum 2013 Elementary School in Buleleng Regency, which amounted to 326 students. The samples were taken by cluster random sampling which amounted to 60 students. The data collected in this study were the results of the dimensions of cognitive processes by using 20 multiple-choice tests and 5 item essays on the ecosystem theme. The hypothesis was tested using inferential t-test statistics. The results show that there are significant differences in the dimensions of cognitive processes between groups of students who were taught with project-based trying activities and groups of students who were taught using conventional learning activities. The optimizing project-based trying activities has a positive effect on the dimensions of students' cognitive processes.PENGOPTIMALAN AKTIVITAS MENCOBA DENGAN BERBASIS PROYEK UNTUK MENINGKATKAN DIMENSI PROSES KOGNITIF SISWAPenelitian ini bertujuan untuk mengetahui perbedaan dimensi proses kognitif antara kelompok siswa yang dibelajarkan dengan aktivitas pembelajaran mencoba berbasis proyek dan kelompok siswa yang dibelajarkan dengan aktivitas pembelajaran konvensional.
