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

This study aims to determine the effect of Genially interactive media supported by the discovery learning model on students' cognitive learning outcomes in the nervous system. This research is motivated by the low level of student active engagement in learning, necessitating innovative media and learning models that support meaningful conceptual understanding. This study used a quasi-experimental method. The subjects consisted of an experimental class using Genially media supported by the discovery learning model and a control class using the expository model. The study was conducted on eleventh-grade students of SMA Negeri 5 Samarinda on the nervous system. The research instrument was an essay test administered before and after the lesson. Data analysis included normality tests, homogeneity tests, hypothesis testing using the independent sample t-test, and N-gain calculations. The analysis results showed that the data were normally distributed and homogeneous. The hypothesis test revealed a significant difference between cognitive learning outcomes in the experimental and control classes. The improvement in cognitive learning outcomes in the experimental class was in the moderate category and higher than in the control class. Thus, Genially interactive media supported by the discovery learning model is effective in improving students' cognitive learning outcomes in the nervous system.

Abstract

This study aims to determine the effect of giving independent assignments on student learning outcomes in the Histology course. The method used was a quasi-experimental design with a pretest-posttest control group design. The study subjects consisted of two classes: a treatment class given independent assignments and a control class without similar treatment. Data were collected through pretests and posttests, then analyzed using paired t-tests and homogeneity of variance tests. The results showed a significant difference between pretest and posttest scores in the treatment class (p = 0.000 < 0.05), while the control class showed no significant difference (p = 0.348 > 0.05). These findings indicate that giving independent assignments can significantly improve student learning outcomes. Thus, independent assignments are effectively implemented as a learning strategy in the Histology course to train students' independence, responsibility, and critical thinking skills.

Abstract

The excessive use of chemical pesticides has a negative impact on the environment and health, so a more environmentally friendly pest control alternative is needed. This study aims to determine the effectiveness of the combination of gamal leaf extract (Gliricidia sepium) and bintaro fruit (Cerbera manghas) as a vegetable insecticide against pests in eggplant (Solanum melongena). The research method used pure experiments with a Complete Random Design (RAL) of five concentration treatments, namely 0% (control), 10%, 30%, 50%, and 70%. The observation data was analyzed using the ANOVA test. The results showed that the combination of gamal leaf extract and bintaro fruit had a significant effect in suppressing pest populations in eggplant plants, with a Fcal value of 11.750 and a significance value of 0.000 (< 0.05). The 70% concentration is the most effective treatment in reducing the intensity of pest attacks compared to other treatments and controls. This success is supported by the content of bioactive compounds, such as flavonoids, saponins, alkaloids, and cerberins that act as contact poisons and stomach toxins in the target insects. These findings suggest that the combination of the two extracts could be a safe, economical, and sustainable alternative to plant insecticides to support the cultivation of horticultural crops without relying on synthetic chemical pesticides.

Abstract

The low level of students' understanding of Biology material, especially on the topic of the body's defense system, is often caused by limitations in the variety of learning media used. This study aims to analyze the effect of the use of flipbook-based learning media on student learning outcomes on body defense system materials, in order to support the implementation of the Sustainable Development Goals (SDGs) at SMA Negeri 2 Tenggarong. This study uses a quasi-experimental approach with purposive sampling techniques, involving 35 students divided into experimental and control groups. The research instrument consists of learning outcome tests and questionnaires, which are used to measure students' cognitive achievement. Data analysis was carried out through hypothesis tests using independent sample t-test and N-gain calculation. The results showed a significant difference between the experimental and control groups, with a significance value of the t-test of 0.00 (< 0.05), and an N-gain value of 0.73 which was categorized as a fairly effective improvement. Flipbook media has been proven to have a positive influence on student learning outcomes in the experimental group. The increase was influenced by internal and external factors, including the quality of flipbook content, the support of learning facilities, and students' motivation and interest in learning. Thus, flipbook learning media can be considered an effective alternative in increasing students' understanding of the body defense system material, as well as contributing to improving the quality of education in line with the Sustainable Development Goals (SDGs).

Abstract

Microbiological contamination is one of the factors that affect food safety, especially in wet noodles which have a high moisture content so they are easily damaged. This study aims to determine the number of Total Plate Numbers (ALT) and identify the presence of Escherichia coli in wet noodles sold at Segiri Market, Samarinda City. The research was carried out using a descriptive analytical method through laboratory testing of five wet noodle samples taken by purposive sampling. ALT testing uses the pour plate method on Plate Count Agar (PCA) media, while Escherichia coli testing is carried out by the Most Probable Number (MPN) method followed by confirmation on Eosin Methylene Blue Agar (EMBA) media. The results of the ALT test showed that two samples met the maximum limit of ALT according to SNI 2987:2015 (≤1.0 × 106 colonies/g), while three samples exceeded the threshold. The MPN test showed that four samples were below the maximum limit according to SNI 2987:2015 (≤10 APM/g) and one sample exceeded the threshold. The EMBA confirmation showed two positive samples of Escherichia coli. These results confirm the importance of applying hygienic practices in the processing, storage, and packaging to reduce the risk of microbiological contamination.

Abstract

The effect of light on stomata has been extensively studied, but studies that specifically observed the effect of light intensity on the size and number of stomata in monocot plants at the Sempaja Arboretum, Samarinda, are still very limited, including monocot plants, and have the potential to be a contextual learning resource for biology education in schools. The purpose of this study is to determine the effect of light intensity on the number and size of stomata in monocot plants in the Sempaja Arboretum. This research was carried out from February to May. This study used a Non-Factorial Group Random Design, with 3 different light intensities (morning, noon, and evening). Based on the results of statistical tests (ANOVA and Duncan's follow-up tests), not all species show statistically significant differences in size and number between times (morning, noon, evening). Some species such as Sri Rejeki (Aglonema sp) and Turmeric (Curcuma longa) show statistically insignificant changes. In other species such as Virginia Flower (Commelina virginica), Palm (Arenga pinnata), and Golden Ivory Betel (Epipremnum aureum), the difference in stomata size between times is more pronounced and significant.

Abstract

The background of this research is learning models that are limited in variation, which makes the students less active, especially in questioning skills. Because of that, this research has a purpose to find out the effect of implementing the Problem Based Learning (PBL) model based on Technological Pedagogical and Content Knowledge (TPACK) on students questioning skills. This research used a quantitative approach with a quasi experimental method and a non- equivalent control group design. The subjects of this research are 70 grade XI students in MAN 2 Samarinda, including class XI-B as the experimental class and class XI-A as the control class. The instruments used in this research are interviewing the teacher, observing the learning activities, and an assessment rubric of students questioning skills. The results of this research showed that students questioning skills in the experimental class increased significantly compared to the control class, as shown by the Mann-Whitney U test with a significance value of 0.015 < 0.05. The number of questions from students in the experimental class was more varied (20 questions) compared to the control class, which had fewer questions (5 questions). The conclusion is that the implementation of the TPACK based Problem Based Learning (PBL) model has a positive effect on students questioning skills in the cell material of Grade XI.
