Abstract

This study aims to determine the effect of the combination of keji beling leaf extract (Strobilanthes crispus) and singkil leaf (Premna corymbose Rottl. et Willd) on the intensity of insect pest attacks on green eggplant (Solanum melongena L.). The study used a Randomized Block Design (RBD) with five treatments, namely control (water) and a combination of extracts at concentrations of 25%, 40%, 55%, and 70%, each repeated five times. The extract was made by maceration method using water as a solvent and additional natural adhesive (3 g detergent). Application was carried out twice per week, and the intensity of insect pest attacks was observed on days 11, 25, 39, and 53 DAP. Data were analyzed using ANOVA and the Least Significant Difference (LSD) test at a significance level of 1%. The results showed that the combination of extracts had a very significant effect on the intensity of insect pest attacks (F count > F table). The 70% concentration gave the lowest attack intensity, which was around 15%. This combination of extracts has the potential to be an environmentally friendly botanical pesticide for controlling insect pests on green eggplant plants.

Abstract

This study aims to determine the influence of the STEM-SDGs approach on improving scientific skills and student learning outcomes on Excretory System material at SMA Islam Samarinda. This study uses a quasi experiment method with a non-equivalent control group design. The research sample was selected through a purposive sampling technique consisting of two groups, namely the experimental class of 26 students and the control class of 26 students. Data analysis was carried out using an independent sample t-test. The results of the study show that the STEM-SDGs approach has a significant effect on improving students' scientific skills, especially in the aspects of observing, reasoning, and communicating, as well as on learning outcomes shown through improving post-test scores. The engineering aspect is the most influential component, because it trains students to design and create projects based on the use of used goods according to the SDGs. Thus, it can be concluded that the STEM-SDGs approach is effective in improving students' scientific skills and learning outcomes through integrative and contextual project-based learning.

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

The purpose of this study is to determine the effect of the differentiated learning approach assisted by Lumio media on critical thinking skills and student learning outcomes in class VII ecosystem materials at SMP Negeri 26 Samarinda. This study uses a Quasi-Experimental method with a Non-Equivalent Control Group Design. The sampling technique was carried out by purposive sampling. The research instruments were in the form of a test of critical thinking skills and learning outcomes which were analyzed using the T-Test test with a significant level of 0.05, and N-Gain to analyze the results. The results showed that the N-Gain of critical thinking skills in the experimental group was 0.62 (medium category), and in the control group was 0.50 (medium category). On the other hand, the N-Gain for learning outcomes in the experimental group was 0.63 (moderate category), while in the control group it was 0.51 (moderate category). The results of the hypothesis test analysis, critical thinking skills, and learning outcomes each had a significant value of 0.00<0.05, so that there was a significant influence of the Lumio-assisted differentiated learning approach on critical thinking skills and student learning outcomes. Thus, this approach is effectively used to improve the quality of learning in the ecosystem material of junior high school grade VII SMP Negeri 26 Samarinda.

Abstract

Technological progress requires innovation in all components of education, one of which is by integrating the Sustainable Development Goals (SDGs) into learning through practicum-based breathing system e-modules. This study aims to analyze the influence of practicum-based respiratory system e-modules on the learning outcomes of grade XI students of SMA Negeri 13 Samarinda in the cognitive, affective, and psychomotor domains in supporting the achievement of SDGs 3. The research method used a quasi experiment type of non-equivalent control group with two subjects (30 students each), one class as an experiment and one class as a control. Instruments include cognitive tests (pretest–posttest) as well as affective and psychomotor observations. Cognitive data analysis used an independent t-test, while affective and psychomotor were analyzed descriptively and converted to qualitative categories. The results showed significant differences in cognitive learning outcomes (sig. 0.000 < 0.05). The affective learning outcomes of both classes were in the good category, with the experimental class showing a higher score of 78.89, while the control class was 74.11. The psychomotor learning outcomes of the experimental class were in the skilled category with an average of 75.09, while the control class was quite skilled with an average of 69.17. Therefore, it is concluded that practicum-based e-modules are effective in improving learning outcomes while fostering health and environmental awareness in accordance with SDGs 3.
