This study aims to determine the difference in learning outcomes of 'Wave courses' between groups of students using cooperative learning models based on inquiry and conventional methods. The sample of this research is Student of Physics Education Department in FPMIPA IKIP Mataram class A and B determined by random sampling technique. Data retrieval was performed with tests for cognitive learning outcomes. Research data were taken through pre-test and post-test scores. The research hypothesis was tested by using t test statistic. The results showed that there were differences in students' cognitive learning outcomes between groups of cooperative learning models based on inquiry with conventional learning model expressed by t-test (2.36)> t-table (1.96) at 5% significance level.

[Title: Implementation of Physics Learning Tools Based on Inquiry Learning with Conflict Cognitive Strategies to Facilitate Critical Thinking Ability]. This study aims to implement physics learning device based on inquiry with conflict cognitive strategy to facilitate student’s critical thinking on the fluid material. The device is implemented in the first semester students of Physics Education Study Program IKIP Mataram academic year 2017/2018 with test design using one group pre-test post-test design. Data collection methods used were questionnaires, tests, and observations, while data analysis techniques used qualitative and quantitative descriptive analysis. The results of the implementation obtained some findings, namely: learning activities can be done well with the high degree of reliability. Student response to learning is very positive with the interest of students to follow the learning. The students' critical thinking skills after the experimentally developed learning tools are critically developed. Based on the results of this study can be concluded that learning tools that are implemented practical, and effectively used to facilitate students' critical thinking skills.

This study aims to analyze the effect of chitosan stirring time from shrimp shells as gold absorber. Experimental research was conducted in this study, where the manufacture of chitosan from shrimp shells began with demineralization (mineral removal) using 1.5 M HCl, deproteination (protein removal) using 3.5% NaOH and deacetylation (acetyl removal) using 60% HCl. The chitosan formed was weighed 0.1 gram (as many as five samples) and then stirred in a 10 ppm Au solution, with a stirring time of 0, 10, 20, 30, and 40 minutes, and its absorption ability to gold was analyzed using AAS (Atomic Absorbsion Spectroscopy) and obtained percentage of absorption respectively 24.79%, 50.89%, 45.64%, 40.52% and 37.87%. From the results of the study, it was found that there was an effect of chitosan stirring time from shrimp shells as gold absorber and the highest absorption at 10 minute stirring was 50.89%.

This study aims to determine the effect of cooperative learning 'STAD type' on physics learning outcomes of students class X SMA Muhammadiyah Masbagik Academic Year 2012/2013. This research is quasi experiment and its population is all class X high school student. The sample of research is 2 classes that have been determined with purposive sampling technique, that is 25 people from class X-1 as experiment class and 24 person from class X-2 as control. The experimental class used the STAD-type cooperative model and control class using the conventional learning model. The normalized gain-averaged scores for the experimental class were 0.45 (medium category) and 0.33 (medium category) for the control class. We conclude that the experiment class is better than the control class. Based on hypothesis test result t-test = 2.12> t-table = 2.012. That is, there is a significant influence of the STAD model on learning outcomes rather than conventional.

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.
