Abstract : This study aims to determine the improvement of student achievement by applying collaborative learning strategy type of predict discuss explain observe discuss explain (PDEODE) to improve student’s of hydrocarbon in class X SMA Negeri 1 XIII Koto Kampar. The study was an experiment with randomized control group pretest-posttest. The sample in this research is class X3 as experiment class and class X1 as control class which is determined randomly after normality test anda homogeneity test. The experimental class is treated with the application of collaborative learning strategy type of predict discuss explain observe discuss explain (PDEODE) while the control class without the application of collaborative learning strategy type of predict discuss explain observe discuss explain (PDEODE). Data analysis for hypothesis testing is done using right-t test. Based on the results of data analysis obtained tct = 3,13 and ttable = 1,67 with = 0,05, dk = 56. tcount>ttable is 3,13 > 1,67 means the application of collaborative learning strategy type of predict discuss explain observe discuss explain (PDEODE) can improve student achievement on hydrocarbon subject in class X SMA Negeri 1 XIII Koto Kampar.

Abstract

Abstract: This research aims to increase students learning achievement by implementation of ARIAS learning model on the chemical bonds subject in the class X MIA SMAN 12 Pekanbaru. The type of research is experimental research with randomized control group pretest-posttest design. The population consisted of 3 classes and the sample consisted of 2 classes randomly selected, namely the X MIA 5 class as the experimental class and the X MIA 6 class as the control class chosen randomly after homogeneity test. The experimental class is applied to the ARIAS learning model, while the control class does not apply the ARIAS learning model. Hypothesis testing uses the right-t-test, based on the results of data analysis obtained that t count> t table is 5.84> 1.67 meaning the implementation of ARIAS learning model can improve student learning achievement on the chemical bonds subject in the class X MIA SMAN 12 Pekanbaru with category increase in learning achievement high that is 0,83Key Words: ARIAS Learning Model, Learning Achievement, Chemical Bonds

Abstract

Isolation, characterization, and in vitro testing against murine leukemia P-388 cell of flavonoid compounds from Bauhinia hullettii Prain stem bark have beenperformed. Isolation was carried out by extraction and fractionation. Extraction usedmeceration method at room temperature to obtain n-Heksana extract, dicloromethaneextract, and etil acetate extract. Based on phytochemical testing, etil acetate extractcontain flavonoid compounds. Extraxct etil acetate was fractionated by vacumcolumn chromatography, gravitation column chromatography, and flash columnchromatography. The fractionation resulted yellow crystal that having melting pointof 188oC - 189oC. The in vitro testing against murine leukimia P-388 cell of isolatedflavonoid compounds show “medium” activity with IC50 = 22,5 μg/ml.Key word : Bauhinia hullettii Prain, Flavonoid, Murine Leukemia P-388 Cell
