Abstract

Aphids (Aphis gossypii) are among the most significant pests that cause considerable damage to various types of plants, making it necessary to apply effective and environmentally friendly control methods. Botanical pesticides have emerged as a promising alternative due to their active metabolite compounds such as tannins, saponins, flavonoids, and acetogenins, which can inhibit pest growth without causing negative impacts on the environment or human health. This study aimed to evaluate the effectiveness of soursop (Annona muricata) leaf extract as a botanical pesticide in controlling aphid infestations. Extraction was carried out using 95% methanol as the solvent, with extract concentrations of 0%, 30%, 35%, 40%, 45%, and 50%. The tests were conducted by spraying the extract onto aphids placed in Petri dishes, with four sprays applied at four-hour intervals over a 24-hour period. Data were analyzed using a one-way ANOVA followed by a post hoc test using SPSS version 29.0. The results showed that soursop leaf extract effectively suppressed aphid populations, with the 45% and 50% concentrations achieving a 100% mortality rate. According to the Regulation of the Minister of Health of the Republic of Indonesia No. 50 of 2017, a pesticide is considered effective if it kills ≥80% of the target insects. Therefore, a 30% concentration is considered sufficient for community use to maintain ecological balance

Abstract

This research is motivated by the rapid development of technology, which has impacted learning in preparing prospective teachers for the digital era. One of the essential competencies required for this preparation is the ability to implement the TPACK model in the learning process to improve the learning outcomes of prospective biology teacher students. This study aims to analyze the effect of implementing the Technological Pedagogical Content Knowledge (TPACK) model on the learning outcomes of prospective biology teacher students in preparing them as educators in the digital era. TPACK is a framework that integrates technology, pedagogy, and content to create more effective and interactive learning experiences. The research method used is quasi-experimental, employing a non-equivalent control group design. The results show a significant improvement in the learning outcomes of students in the experimental group compared to the control group. The implementation of TPACK also enhances students' technological skills, which are crucial for their preparation as teachers in the digital era. This study concludes that the application of TPACK not only has a positive impact on cognitive learning outcomes but also fosters a positive attitude towards the use of technology and improves students' psychomotor skills.

Abstract

This study highlights the importance of developing 21st-century competencies, particularly students’ abilities to explain scientific phenomena, design investigations, and interpret data and evidence. The topic of Protists was chosen due to its high diversity and complexity, which often makes it difficult for students to understand, requiring a learning strategy that emphasizes active exploration and concept discovery. The study aimed to examine the effect of the Discovery Learning model on students’ scientific literacy in biology. A quasi-experimental pretest–posttest control group design was employed with two purposively selected tenth-grade classes in a senior high school. The experimental class (n = 20) used the Discovery Learning model, while the control class (n = 20) received conventional instruction. A scientific literacy test based on PISA indicators was used as the instrument. Results showed the experimental class’s mean score increased from 36.33 to 83.33, with an N-Gain of 0.70 (high category). Normality (p > 0.05) and homogeneity (p > 0.05) assumptions were met, and One-Way ANOVA (p < 0.05) indicated a significant difference, suggesting that Discovery Learning effectively improves students’ scientific literacy through active exploration, data analysis, and concept discovery.
