Abstract

This study aims to determine the effect of the group investigation cooperative learning model assisted by audio visual aids on the motivation and learning outcomes of class X SMAN 3 Pekanbaru. This research was conducted in class X of SMAN 3 Pekanbaru in the 2022/2023 Academic Year. The research design used was quasi-experimental, using the matching only pretest posttest control design. The research sample was class X students with 36 experimental and 36 control classes respectively taken by Simple Random Sampling. Data collection was carried out through pretest, posttest and observation sheets. Based on the research results obtained for the learning motivation questionnaire value in the control class was 2.48 with a percentage value of 62.10% in the medium category, while for the learning motivation questionnaire value in the experimental class given the treatment of cooperative learning model group investigation type of 2,97 with a percentage value of 74.47% in the high category. Based on these categories, there was an increase in learning motivation in the experimental class which was given treatment with the group investigation type cooperative learning model assisted by audio-visual aids. For the mean N-Gain in the control class 0.29 (low), while in the experimental class 0.52 (moderate). On the results of the N-Gain t-test the value of Sig. (2-tailed) Equal variances not assumed on the output of the Independent sample test value is 0.000 <0.05 then reject Ho which means that there is a significant difference between the N-Gain control class which is given treatment with conventional learning and the experimental class which is given treatment with cooperative learning model with the type of group investigation assisted by audio visual which shows an increase in learning outcomes. Thus learning using the cooperative learning model type group investigation assisted by audio visual aids in virus material affects the motivation and learning outcomes of class X SMAN 3 Pekanbaru in the 2022/2023 Academic Year.

Abstract

According to data from the 2019 IUCN Red List, the Aquilaria malaccensis species is included in the "Critically Endangered" category and the Castanopsis argentea species is included in the "Endangered" category. This study aims to determine the comparison of abundance and associations of Aquilaria malaccensis Lam. and Castanopsis argentea (Blume) A.DC. in Sultan Syarif Hasyim Forest Park, Riau Province. Data collection is carried out by making observation plots. In this research, an observation plot will be made measuring 20 m x 20 m to analyze tree vegetation. The research plot was determined deliberately (purposive sampling) and measurements were carried out in places where there were Aquilaria malaccensis and Castanopsis argentea trees. The population in this study is the area of ​​Tahura Sultan Syarif Hasyim in Siak Regency, namely, 2,400 Ha. The sample in this study was taken with a sampling intensity of 0.1%. So, the sample in this study covers an area of ​​24,000 m2. The type of data collected is primary data consisting of data on the abundance and association (with other plants) of Aquilaria malaccensis and Castanopsis argentea in Tahura SSH, Riau Province as well as secondary data in the form of the general condition of the research location, maps and the results of research that has been carried out, thesis or journals related to the title to be researched. Data analysis in the form of an Important Value Index, Diversity Index, and associations with other types. The results of data analysis can determine the abundance and associations of Aquilaria malaccensis Lam. and Castanopsis argentea (Blume) A.DC. in Sultan Syarif Hasyim Forest Park, Riau Province. The research results show that the Castanopsis argentea species has a higher abundance of 0.03 than Aquilaria malaccensis, which is 0.003. The highest association of Castanopsis argentea was 0.5 with Palaquium burkii, while the highest association of Aquilaria malaccensis was 0.8 with Sloetia elongata.
