Abstract

Penelitian ini bertujuan untuk mengetahui aktivitas dari ekstrak daun Sterculia comosa Wallich terhadap pertumbuhan bakteri Klebsiella pneumonia dan Streptococcus viridans. Ekstraksi dilakukan dengan metode maserasi. Pengujian antibakteri dengan menggunakan metode dilusi. Berdasarkan hasil penelitian menunjukkan bahwa ekstrak daun Sterculia comosa Wallich berpengaruh sangat nyata terhadap pertumbuhan bakteri Klebsiella pneumonia dan Streptococcus viridans. Konsentrasi ekstrak daun Sterculia comosa Wallich yang berpengaruh dalam menghambat pertumbuhan bakteri Klebsiella pneumonia adalah pada konsentrasi 200 mg/ml dengan rata-rata jumlah koloni bakteri yang hidup 163 CFU dan konsentrasi tertinggi 1600 mg/ml dengan rata-rata jumlah koloni yang hidup sebanyak 75 CFU, sedangkan pertumbuhan bakteri Streptococcus viridans terhambat pada konsentrasi minimal 200 mg/ml dengan rata-rata jumlah koloni bakteri 147 CFU dan konsentrasi tertinggi pada 1600 mg/mL dengan rata-rata jumlah koloni yang hidup sebanyak 63,67 CFU. Sementara konsentrasi yang dapat membunuh bakteri dalam penelitian ini belum ditemukan untuk kedua bakteri tersebut. Hasil penelitian ini berimplikasi pada pengembangan penelitian dan memperkaya temuan pada tumbuhan berpotensi obat.

Abstract

This study aims to explore the perceptions of tenth-grade students regarding the effectiveness of the Problem-Based Learning (PBL) model in Biology classes at SMA Negeri Kie. Employing a descriptive quantitative method, the research focuses on analyzing students' responses across six key indicators of PBL implementation. The findings reveal that the indicator of PBL application in Biology learning received a response rate of 84%, the influence of PBL on learning motivation reached 81%, active participation and engagement scored 80%, problem-solving skills were rated at 78%, the impact on learning outcomes reached 79%, and the influence on overall involvement and activity was 78%. The average response across all indicators was 80%, indicating that students' perceptions of the effectiveness of the PBL model fall into the "very good" category. These results suggest that the implementation of the Problem-Based Learning model positively contributes to the learning process in Biology, particularly in enhancing students' motivation, engagement, and critical thinking abilities.

Abstract

Education is the primary means of improving the quality of human resources, thus the success of the learning process is an important indicator of educational quality. One of the internal factors that plays a major role in determining student learning success is learning motivation. This study aims to determine the relationship between learning motivation and learning outcomes in Integrated Science subjects for grade VIII students at the UPTD of SMPN 1 Kupang Tengah. This study uses a quantitative approach with a correlational research type. The study was conducted in March of the 2024/2025 academic year with a sample of 60 students from grades VIII C and VIII D. The research instruments were a learning motivation questionnaire and a document of Integrated Science learning outcomes. Data collection techniques were carried out through questionnaires, observations, interviews, and documentation studies. Data analysis used the Pearson Product Moment correlation test with the help of the IBM SPSS Statistics 22 program, and was supported by validity, reliability, normality, homogeneity, and hypothesis testing. The results of the correlation analysis obtained a value of r = 0.594 with R Square = 37.21% which means that learning motivation contributes 37.21% to student learning outcomes. The hypothesis test shows a calculated F value = 90.850 with a significance of 0.000 < 0.05, so it can be concluded that there is a positive and significant relationship between learning motivation and learning outcomes. Thus, the higher the student's learning motivation, the better the Integrated Science learning outcomes achieved

Abstract

The Problem Based Learning (PBL) model is a problem-based learning that trains activeness, critical thinking, and problem-solving skills through educational interactions. This study aims to improve motivation and learning outcomes of Global Warming material for class X IPA students of SMA Negeri 9 Kupang through the PBL model assisted by animated videos. This type of research is Classroom Action Research which is carried out in two cycles, including the stages of planning, implementation, observation, and reflection. The research subjects were 20 students with data collection techniques in the form of observation, tests, and questionnaires. The results of the study showed a significant increase in cycle II. The average value of student learning outcomes increased with a completeness level reaching 90%. Student learning activities also increased to 92.85%, where the researcher's activities in both cycles were categorized as successful. Student learning motivation increased from 76.31% in cycle I to 87.75% in cycle II. It was concluded that the application of the Problem Based Learning model assisted by animated videos effectively increased student motivation and learning outcomes on global warming material at SMA Negeri 9 Kupang.

Abstract

This study aims to determine the improvement in student learning outcomes through the influence of the SSCS learning model on the circulatory system in eighth-grade students at SMP Negeri 2 Kupang City in the 2025/2026 academic year. This study was a quasi-experimental study with a pretest-posttest control group design. Two sample classes were used: the experimental class using the SSCS learning model and the control class using the conventional learning model. Random sampling was used for sampling. The assessment instrument consisted of 10 multiple-choice questions and 5 essay questions. Learning outcome data, in the form of pretest-posttest results from both classes, were analyzed quantitatively using t-tests, preceded by prerequisite tests for normality and homogeneity. Based on the results of the treatment of the two classes, the normality values ​​of the pretest-posttest of the experimental class were obtained (0.063 > 0.05) and (0.100 > 0.05) while in the homogeneity test on the pretest of the control-experimental class (0.803 > 0.05) and posttest of the control-experimental class (0.172 > 0.05) so that the data were normally distributed and homogeneous, and the average posttest learning outcomes in the control class were 64.53 in the very low category while the average posttest results in the experimental class were 73.09 in the medium category, and supported by the results of the t-test with the results that there was an influence of the SSCS learning model on the Learning Outcomes of Class VIII students at SMP Negeri 2 Kupang City on the Circulatory System Material. This shows that the influence of the SSCS learning model can influence student learning outcomes to increase in class VIII of SMP Negeri 2 Kupang City.

Abstract

Contemporary learning developments in the 21st century demand adaptations in teaching methods, where project-based assignments foster creativity, collaboration, and real-world problem-solving among prospective biology teachers. Initial observations indicated students lack innovation without lecturer guidance, necessitating response analysis to evaluate effectiveness. This study adopted a descriptive quantitative approach, collecting data through a Likert-scale questionnaire (strongly disagree, disagree, moderately agree, agree, strongly agree) covering 8 aspects: topic understanding, creativity and innovation, collaboration, time management, product quality, project presentation, reflection/process, and benefits. It involved 84 student respondents, with data processed using Microsoft Excel and SPSS version 21.Analysis results showed student responses to the project-based assignment model in contemporary learning lectures fell into the "very good" category, averaging 82.20%. The highest response was on the indicator of real benefits from projects in developing knowledge, skills, and general learning experiences (85.00%). The lowest was on efficient project completion time management (79.76%). These findings demonstrate the model's high effectiveness for current biology education.
