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

The low learning outcomes of students in science learning, particularly biology, are due to the perception that biology material is difficult and boring. One way to improve students' learning outcomes is by using the guided inquiry learning model. This study aims to determine the effect of the guided inquiry learning model on the learning outcomes of Grade VII students in the topic of interactions between living organisms and their environment at SMPK St. Agustinus Adisucipto Penfui Kupang.The sample for this research consisted of Grade VII C students as the experimental class, using the guided inquiry learning model, and Grade VII D students as the control class, using the direct instruction model. The type of research employed was quantitative with a quasi-experimental design. The research design used was the Nonequivalent Control Group Design. Data analysis techniques included descriptive analysis and inferential analysis. The results of the study showed that the average learning mastery of students in the experimental class had a pretest score of 53.23 and a posttest score of 81.61, with an N-Gain of 0.60, categorized as high. Meanwhile, the control class had an average pretest score of 45.5 and a posttest score of 72.5, with an N-Gain of 0.48, categorized as moderate. Based on the ANCOVA test results, the significance value was 0.001 < 0.05, which led to the rejection of the null hypothesis (Ho) and the acceptance of the alternative hypothesis (Ha). Thus, it can be concluded that the guided inquiry learning model significantly affects the learning outcomes of Grade VII students in the topic of interactions between living organisms and their environment at SMPK St. Agustinus Adisucipto Penfui Kupang.

Abstract

Methicillin-resistant Staphylococcus aureus (MRSA) refers to a group of bacteria that cause infections and present a challenge in treatment due to their resistance to several antibiotics. Therefore, research is needed to discover endophytic bacteria from Catharatus roseus capable of producing new antibiotics. This study aims to identify endophytic bacteria from C. roseus plants originating from Timor Island, as producers of effective antibacterial compounds against MRSA. Antibacterial activity tests were conducted on two types of test bacteria, namely MRSA and Escherichia coli. DNA extraction was performed using the PrestoTM Mini dDNA kit Bacteria, and amplification of the 16S rRNA gene was carried out. The research found bacterial isolates showing morphological similarities to Bacillus sp. Screening results indicated that four bacterial isolates exhibited high potential antibacterial activity against MRSA, as evidenced by the formation of inhibition zones with diameters of approximately 25 mm-35 mm. Amplification of the four endophytic bacterial isolates from C. roseus identified them as Paenibacillae FaCH2, Bacillae BoCH3, Aneurinibacillae BoCH5, Aneurinibacillae BiCH8, which are new species based on 16S rRNA gene similarity of less than 97%. In conclusion, endophytic bacteria from C. roseus producing antibacterial compounds against MRSA have been successfully identified. This is beneficial to society because the antibacterial compounds produced can serve as a basis for developing new drugs that are effective against MRSA infections, considering the increasing antibiotic resistance against MRSA.
