Abstract

The development of technology in the education sector today is not accompanied by wise use by students. One way to increase the productivity of technology use by students is through schools, where teachers act as facilitators. This certainly poses a challenge for teachers to maximize the role of technology in schools despite differences and limitations so that learning becomes effective. Teachers' perceptions of technology are important to analyze in efforts to improve the quality of technology-based learning. This study aims to determine teachers' perceptions of the effectiveness of biology learning based on technological knowledge at Samarinda Ulu District High School and the factors influencing it. The methods used are qualitative and quantitative, with measurement tools in the form of questionnaires and interview sheets. Data were analyzed using descriptive statistical analysis. Based on the questionnaire responses from 7 biology teachers at SMA Kecamatan Samarinda Ulu, the analysis of teachers' perceptions of the effectiveness of technology-based biology learning revealed a score of 71.42%, indicating that the majority of teachers have a very positive perception of the effectiveness of technology-based learning. Factors influencing this include teachers' and students' ability to use technology, the availability of infrastructure, the suitability of technology to the material presented, the diversity of applications used in learning, and discipline and motivation in learning.

Abstract

Insect pest attacks are one of the main obstacles in cultivating striped spinach (Amaranthus tricolor L.), because they reduce the quality and quantity of the harvest. Long-term use of synthetic pesticides has a negative impact on the environment and health. This study aims to test the effectiveness of the combination of soursop leaf extract (Annona muricata L.) and garlic (Allium sativum) as a botanical pesticide on the intensity of pest attacks. The study was conducted using a Randomized Block Design (RBD) with five concentration treatments (0%, 25%, 45%, 65%, and 85%) and five replications. Data were analyzed using ANOVA and BNT test at the 1% level. The results showed that the botanical extract treatment had a significant effect on reducing the intensity of pest attacks, with a concentration of 85% giving the most effective results (Fcount 236.05 > Ftable 4.77). The treatment of plant leaves showed lower damage than the control. This effectiveness is thought to be due to the content of active compounds, such as flavonoids, saponins, tannins, acetogenins, and alkaloids which are toxic to pests. In conclusion, soursop leaf and garlic extracts have the potential to be environmentally friendly botanical pesticides and can be used as an alternative to control striped spinach plant pests.

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

This research is motivated by the lack of variety in learning models implemented at SMPN 45 Samarinda, which causes students to tend to be passive and lack creative thinking skills. This study aims to analyze the effect of the Project-Based Learning (PjBL) model with a Design Thinking approach on the creative thinking skills of seventh-grade students. The method used was a quasi-experimental design with a nonequivalent control group design. The sample consisted of two classes: VIIA as the experimental class and VIIB as the control class, each with 25 students. The research instrument was a pre-test and post-test essay test based on creative thinking indicators. Data analysis used an Independent Sample t-Test with a significance level of 5%. The results showed that the calculated t value (20.545) > t table (1.677), so H0 was rejected and Ha was accepted. Thus, the implementation of the Design Thinking-based PjBL model had a significant effect on improving students' creative 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).
