This research aimed at knowing whether the use of TGT (Teams Games Tournament) cooperative learning model completed with Power Point media resulted better student learning achievement than the use of TGT cooperative learning model on Atomic Structure and Periodic System of the Elements lesson at the tenth grade of State Islamic Senior High School 4 Kampar in the Academic Year of 2017/2018. This research was Quasi-experiment with pretest and posttest design conducted in two classes—the first experimental group taught by using TGT cooperative learning model completed with Power Point media and the second experimental group taught by using TGT cooperative learning model. Simple random sampling technique was used in this research. The techniques of collecting the data were interview, preliminary data test that was homogeneity test, final data tests that were pretest and posttest, and documentation that was used to strengthen the obtained data. The research findings showed that posttest mean score of the first experimental group was 79 and the second group was 76,25. Final data analysis was using t-test, so it was obtained that tobserved was 2.21 and ttable was 2.02 at 5% significant level. tobserved was higher than ttable, so H0 was rejected and Ha was accepted. It meant that there was an effect of implementing TGT cooperative learning model completed with Power Point media toward student learning achievement on Atomic Structure and Periodic System of the Elements lesson at State Islamic Senior High School 4 Kampar, and the coefficient of effect was 11.38%.

AbstractThis research aimed at knowing whether there was or not an effect and increase of values of Community of Inquiry (CoI) based Blended Learning model toward student learning achievement. It was Quasi Experimental research—a research that used an Experimental group and a Control group determined the difference of two variables. The samples of this research were 2 groups—the tenth-grade students of Natural Science 4 (the Experimental group) that were 36 students taught by using Community of Inquiry based Blended Learning model and the students of Natural Science 5 (the Control group) that were 34 students taught by using Conventional learning. The techniques of collecting the data were written pretest and posttest. The collected data were analyzed by using Independent Sample t test and to see the effect of using the coefficient of determination. The final data processing results obtained tcount of 1.778 while the value of ttable at a significant level of 5% = 1.684 then H0 is rejected and Ha is accepted. Means there is an influence of blended learning model based on community of inquiry (CoI) with conventional learning models on student learning outcomes. To determine the magnitude of the effect of the treatment used the coefficient of determination formula and the results obtained by 0.04, so the coefficient of influence (Kp) obtained is equal to 4%.Keywords : Blended Learning, Community of Inquiry, Learning Achievement, Atomic Structure and Periodic System of the ElementsAbstrakPenelitian ini bertujuan untuk mengetahui ada atau tidaknya pengaruh dan peningkatan nilai model Blended Learning berbasis Community of Inquiry (CoI) terhadap prestasi belajar siswa.

AbstractGrowth and development in the industrial sector has made residents contribute to the waste that enters the environment. Imperfect waste treatment causes pollution to the environment and waters, so the water quality has decreased. The decline in water quality is caused by water pollution where foreign substances enter and leave. One of them is heavy metal. A number of studies have been carried out to treat and remove heavy metal ions in waters, one of which is the adsorption process. The adsorption method usually utilizes waste that is often disposed of and even modifications or activations are carried out in order to expand the surface area of the absorbent material. This review article discusses the adsorption method by utilizing Indonesian typical fruit peel waste for the last 10 years. From several studies collected, it was found that waste from typical Indonesian fruit peels was effective in absorbing heavy metal waste. Fruit peel waste that has high effectiveness is lemon peel waste with an absorption capacity of 98.4% on Cd metal, with an pH 8 and optimum contact time of 2 hours. This review can be an alternative for the manufacture of other absorbent materials and eliminate metal pollution in the aquatic environment.Keywords : Water pollution, Heavy Metals, Adsorption, Indonesian Fruit Peel Waste
