Abstract

This study aims to determine the effectiveness of the team games tournament learning model assisted by the monopoly game in improving student learning outcomes and activeness in the material of classification of living things for grade VII at SMP Negeri 48 Samarinda. The selection of this school was based on the problems found, namely the learning process that still tends to be teacher-centered, low student participation in learning activities, and the existence of a school policy that does not allow students to bring mobile phones, thus limiting the use of digital learning media in the classroom. The method used was a quasi-experiment with a pretest–posttest control group design, with samples determined through cluster random sampling techniques, so that two classes were obtained, namely the experimental class and the control class, each consisting of 24 students. The research variables included cognitive learning outcomes and student activeness, with instruments in the form of tests (pre-test and post-test) and an activeness questionnaire. Data analysis was carried out using normality tests, homogeneity tests, and independent sample t-tests. The results showed that the average pre-test scores for both classes were relatively similar, while the average post-test scores for the experimental class were higher than those for the control class. The percentage of student activity in the experimental class was in the very active category, while the percentage of student activity in the control class was in the active category. The t-test results showed a significance value of 0.000 < 0.05, indicating a significant difference between the two classes. Thus, the Monopoly game-assisted team games tournament learning model is effective in improving student learning outcomes and engagement.

Abstract

The study aimed to determine the effect of Asian Ticktrefoil leaf extract (Desmodium heterocarpon (L.) DC.) and Pineapple Weevil (Ananas comosus (L.) Merr.) as botanical pesticides on the intensity of insect pest attacks on Green Mustard (Brassica juncea L.) plants. This type of research is an experimental study conducted in the Agricultural Land of Jalan Jayakarta RT. 19, Rawa Makmur Village, Palaran District, Samarinda City. The research design used a Randomized Block Design (RBD) with 5 treatments, namely: T0 (control), T1 (detergent + water), T2 (50% Asian ticktrefoil leaf extract), T3 (50% pineapple weevil extract), and T4 (50% combination of Asian ticktrefoil leaf and pineapple weevil extract) with 5 replications. The data analysis results showed that the calculated F for each treatment, respectively, was (457.05) > F (4.77) at a significance level of 1%. This demonstrates a highly significant effect of the application of Asian Ticktrefoil (Desmodium heterocarpon (L.) DC.) leaf extract and Pineapple Weevil (Ananas comosus (L.) Merr.) as botanical pesticides on the intensity of insect pest attacks on mustard greens (Brassica juncea L.). These findings demonstrate the potential of locally sourced botanical pesticides as an environmentally friendly pest control alternative in mustard greens cultivation.
