Abstract

To obtain high learning outcomes, a teacher is required to teach students to use the right learning model. This study aims to analyze the effect of Problem Based Learning on the interaction of living things with their environment on learning outcomes in junior high schools. Experimental research with pretest posttest nonequivalent control group design. The object of this study is the results of student learning on the cognitive, affective, and psychomotor aspects. The sample used was two classes of students, as an experimental class and a control class and each of 28 students. Data collection techniques used were pretest-posttest, observation, and documentation. The research data were analyzed using the Independent Sample T-Test and the N-Gain test. The results showed that the average learning outcomes in the experimental class were higher than the average learning outcomes in the control class (N-gain 76>36.54); on Affective (73.21> 64.73) and Psychomotor (77.68> 65.62) aspects. Then analyzed using the Independent sample T-test. Based on the analysis of research results and discussion, it can be concluded that Problem Based Learning learning in the interaction of living things with their environment has an effective effect on junior high school student learning outcomes.

Abstract

This study aims to examine the Implementation of Indigenous Knowledge-Laden Leaflets on Student Learning Outcomes on Global Warming Material. This study used a quasi-experimental method with a Nonequivalent control group design. This study used classes XA, XD, XE and XF, each class consisting of 36 students. In the class there is a selection of criteria, for class XA with high class criteria, class XD with medium class criteria, class XE with low class criteria, and class XF as a control class (Biology Teacher document). The research instrument is in the form of cognitive, affective, and psychomotor results. Data analysis of learning outcomes using one way anova test with normality test and homogeneity test. The results of the calculation of learning outcomes with one way anova test obtained a significance value (2-tailed) of (0.000) < (0.050) then the null hypothesis (H0) is rejected. And then the further test obtained a significance probability value of (0.917) > (0.050), therefore (H0) is accepted. This means that the treatment has an effect on student learning outcomes and the results of further tests have no effect on the learning outcomes of experimental classes (high, medium, and low clas).

Abstract

The purpose of this study was to determine the biology learning outcomes of SMA Negeri 1 Teras class X students using teaching materials containing indigenous knowledge in the 2023/2024 school year on environmental change material. This type of quantitative research with a Quasi Experiment design, this form of Quasi Experiment uses Nonequivalent Control Group Design. This research was conducted in two classes, namely the control class and the experimental class. In this study, an initial test (pretest) was conducted before treatment and a final test (posttest) was conducted after treatment. A total of 72 students were sampled in this study. The research instrument was a test of cognitive, affective, and psychomotor learning outcomes. Analysis of learning outcomes data using normality test, homogeneity test and independent sample t-test test. The results of the calculation using the independent sample t-test test obtained a significance value (2-tailed) of 0.033 <0.050, so the null hypothesis (H0) is rejected. It can be concluded that the use of teaching materials containing Indigenous Knowledge is better and proven to have an effect on the learning outcomes of Biology class X students of SMA Negeri 1 Teras in the 2023/2024 school year on environmental change material.

Abstract

Effective and efficient broiler management is necessary. The smaller the feed conversion ratio value, the more effective and efficient chicken maintenance. Efforts to reduce feed conversion include reducing feed consumption by adding EM-4 probiotics and herbal spices. The purpose of this study was to determine the effect of the addition of EM-4 probiotics and herbal spices on the feed conversion ratio of broiler chickens (Gallus doemesticus). Experiments were conducted using a sample of 20 broiler chickens aged 14 days, with treatments P0H0 (control), P0H1 (6g herbs), P1H0 (0.6% probiotic EM-4), P1H1 (6% Probiotic EM-4 + 6g Herbs) which were divided into four treatment groups with 5 replicates. The results showed that the treatment with 0.6% EM-4 probiotics + 6 g herbal spices had the lowest feed conversion. Then the effect of probiotics and herbal spices on broiler feed conversion rate was analyzed by Anova test, followed by Duncan test. It can be concluded that the addition of 0.6% EM-4 probiotics and 0.6% herbs is the most optimal feed ratio. These findings can help farmers, entrepreneurs or the general public who use EM-4 and herbs that can optimize their income by reducing the feed conversion ratio of broiler chickens.
