Abstract

The use of the discovery learning model at SMA Negeri 1 Amfoang Utara has been implemented by biology subject teachers, but student learning outcomes are still brought to KKM standards, this is caused by the lack of enthusiasm of students in learning so that it influences student learning outcomes. Therefore, to improve student learning outcomes, teachers act as guides by providing opportunities for students to learn actively and directing student learning activities in accordance with learning objectives, using the discovery learning model. discovery learning model, able to increase student activity in the classroom. The aim of this research is to determine the effect of the discovery learning model on the learning outcomes of class XI MIA students at SMA Negeri 1 AMFOANG NORTHWEST KUPANG DISTRICT for the 2022/2023 academic year. The type of research used is quantitative research with quasi-experimental methods. The population in this study were all students in class XI MIA at SMA Negeri 1 AMFOANG NORTHWEST KUPANG DISTRICT, with the research sample consisting of classes XI MIA1 and XI MIA2. The data analysis technique in this research uses descriptive analysis and inferential analysis. The research results showed that the average learning outcomes of students in the experimental class obtained a pretest score of 44.45, increasing to 84.09 after being given the posttest. Meanwhile, in the control class, the pretest score was 45.00, increasing to 77.88 after being given the posttest. The number of students who completed in the experimental class was 87.87% and those who did not complete was 12.12%. In the control class the number of students who completed was 66.66% and those who did not complete was 33.33%. Based on the results of the one-way anacova test, a probability value (sig) of 0.004 was obtained, which was smaller than the set value, namely 0.05. This shows that Ha (the discovery learning model has an effect on student learning outcomes) is accepted and H0 (the discovery learning model has no effect on student learning outcomes) is rejected. Based on the research results and discussion of the data obtained, it can be concluded that the discovery learning model influences the learning outcomes of class XI MIA students on the human body defense system material The human body's defense system at SMA Negeri 1 Amfoang northwest Kupang district

Abstract

Diversity of Echinodermata Types in the Oesina Beach Littoral Zone, West Kupang District, Kupang Regency. This research aims to determine the types of Echinoderms in the Oesina Beach Littoral Zone, West Kupang District, Kupang Regency. This research was carried out at Oesina beach, Lifuleo village, West Kupang District, Kupang Regency on 5-10 May 2023 This research uses a quantitative descriptive approach using an exploration method, namely conducting direct observations of echinoderms on Oesina beach, Lifeleo Village, West Kupang District, Kupang District. The research results found that from 4 transects in 15 plots, various types of Echinodermata were found, namely 7 species consisting of 6 families, 6 classes, 4 orders, 6 genera and 2 sub-phyla with a total of 120 individuals. The phylum Echinodermata is the class of sea stars (Asteroidea), brittle stars (Ophiuroidea), sea cucumbers (Holothuroidea) and sea urchins (Echinoidea). Species found at the observation location include Archaster typicus, Ophiarachna affinis, Protoreaster nodulosus, Echinometra oblonga, Echinometra mathae, Holothuria leucospilota, Tripneustes gratilla. The results of calculating the diversity index (H) of echinoderms on Oesina beach, Lifeleo Village, West Kupang District, Kupaten District, are in the high category The conclusion is that the level of diversity of echinoderms in the Oesina Coastal Littoral Zone, West Kupang District, Kupang Regency is 1.83135 which shows high diversity.

Abstract

The students' learning outcomes are still low due to the teaching model used by teachers being suboptimal and the lack of utilization of learning media. A teaching model that can address this issue is the Discovery Learning model. The purpose of this study is to determine the effect of the Discovery Learning model assisted by audiovisual media on the learning outcomes of Grade VII students on the topic of Interactions Between Living Organisms and Their Environment at SMPN 1 Nagawutung Lembata during the 2023/2024 academic year. This research employs a quantitative approach using a quasi-experimental method with a Non-Equivalent Control Group Design. The sampling technique used is purposive sampling. Data analysis techniques include descriptive data analysis and inferential data analysis. The study results show that the average learning outcomes of students in the experimental class applying the Discovery Learning model assisted by audiovisual media were as follows: pretest average score of 50.15, posttest average score of 81.56, and N-Gain of 0.62, categorized as high. Meanwhile, the control class using the direct teaching model had a pretest average score of 45.15, posttest average score of 66.40, and N-Gain of 0.39, categorized as low. Based on the ANCOVA test results, the significance level was 0.043 < 0.05, indicating that the null hypothesis (H?) is rejected, and the alternative hypothesis (H?) is accepted. Based on these findings, it can be concluded that the Discovery Learning model assisted by audiovisual media affects the learning outcomes of Grade VII students on the topic of Interactions Between Living Organisms and Their Environment at SMPN 1 Nagawutung Lembata during the 2023/2024 academic year.
