AbstractThe lack of learning resource availability developed in the school constituted a background of this research. Thus, developing chemistry pocket book teaching material with Green Chemistry oriented Chemo-Entrepreneurship approach on Acid Base Lesson was designed in this research. 4-D development model was used in this research until Develop stage. The subjects of this research were a media expert lecturer, a material expert teacher, 2 Senior High School teachers for media practicality test, and 10 students at State Senior High School 4 Pekanbaru for knowing the response to the media. Data collected in this research were in the forms of interview and questionnaire. Instruments of collecting data were validity and response questionnaires. The data obtained were analyzed by using qualitative and quantitative descriptive analysis techniques. Based on the research findings, the media validation percentages were 91.30% by the material expert and 89.28% by the media expert with very valid assessment criteria, the percentage of teacher practicality test was 95% with very practical criterion.Keywords : Pocket Book, Chemo-Entrepreneurship Approach, Green Chemistry, Acid Base

AbstractThe aim of this research was to know the influence of applying Contextual Teaching And Learning model by using Prezi Desktop mediatoward the students’ outcome on colloid learning. This research was experimental research by using pretest-posttest control group design and. The technique of collecting data was using test, observation, and documentation. The sample of this research was using random sampling. 32 students of 11th-grade science 5 serve as an experimental class. They were given the treatment of Contextual Teaching And Learning by using Prezi Desktop media, while 33 students of the 11th-grade science class 4 serve as a control classthat was given the conventional technique. The research found the final data used t pooled variance,so it was foundtquantification = 2,11and ttabel= 2,00 on the significant part and showed that tquantification>ttable. Thus, Ho was rejected and Ha was accepted. The coefficient category is 6.60%. So it can be concluded that Contextual Teaching and Learningmodelby using Prezi Desktop mediacan give a positive effect on the students outcome of chemical achievement especially on colloid learning of 11th-grade science class at State Senior High School 4 Pekanbaru.Keywords: Contextual Teaching And Learning, Prezi Desktop, Outcome

AbstractThis research is prompted by students’ low learning outcomes. One of the ways that can be performed to increase students’ learning outcomes is Student Teams Achievement Division (STAD) learning method by using virtual laboratory. This research is aimed at looking at the effect of STAD learning method by using virtual laboratory toward students’ learning outcomes in Redox Reaction material of grade 10 students at State Senior High School 1 Mandau. This research is a quasi-experiment research by using Pretest-Posttest Control Group Design with two sample classes: Class X 3 as experiment research and Class X 4 as control class. In this research, the meeting was conducted for four times. The techniques of collecting the data in this research are Homogeneity test as initial data, Pretest and Posttest as final data, Interview, and Documentation. Initial and final data are analyzed by using t-test. This research shows that there are some differences on students’ learning outcomes between experiment class and control class. Final data analysis generates the value of tcounting = 2.8904 and ttable = 1.9983 that shows tcounting > ttable. As Ho is rejected, it can be concluded that there is an effect of applying STAD learning method by using virtual laboratory toward students’ learning outcomes which is as much as 11.70%.Keywords: STAD, virtual laboratory, redox reaction
