Abstract

This study aims to determine the effect of giving neem leaf extract (Azadirachta indica A. Juss) as a vegetable pesticide against Helopeltis antonii pests on cocoa plants (Theobroma cacao L.). This research was conducted in Hebing Village, Mapitara District, Sikka Regency, which lasted for one month, from March 1 to March 31, 2023. The research method used was an experimental method with a Randomized Block Design (RBD). The factor studied was the effect of neem leaf extract on the number of punctures by Helopeltis antonii on cocoa pods, which consisted of 5 treatments and 4 replications. The treatments used in this study were P0: Without neem leaf extract (control), P1: 30ml neem leaf extract, P2: 60ml neem leaf extract, P3:90ml neem leaf extract, and P4: 150ml neem leaf extract. The parameter measured was the number of punctures by Helopeltis antonii. Research data were analyzed by normality test and homogeneity test. The normality test shows that the significance value is 0.200, which is a significant value > 0.05, meaning that the data is declared normal. The homogeneity test shows a significance value of 0.372, which is a significant value > 0.05 so the data is declared homogeneous. Based on the results of the ANOVA test, it was concluded that the administration of neem leaf extract affected the number of Helopeltis antonii pest pricks between treatments.

Abstract

Bilingual instruction is a learning strategy that can help students understand learning materials while bridging the gap between the language used at school and the language spoken in daily life. This study aims to analyze the effect of bilingual instruction on students' understanding of the Ecosystem topic at SDK Gusung Karang, Koja Gete Village. The study was motivated by the fact that students predominantly use the Sikka language in their daily communication, making it difficult for them to understand lessons delivered solely in Indonesian. This study employed a qualitative approach with a descriptive method. The research participants consisted of the fourth-grade homeroom teacher and fourth-grade students at SDK Gusung Karang. Data were collected through observations, interviews, and documentation and analyzed using data reduction, data display, and conclusion drawing techniques. The findings indicate that bilingual instruction has a positive impact on students' understanding of the Ecosystem topic. The use of the Sikka language helps students comprehend basic concepts, increases classroom participation, and enhances their confidence during the learning process. Meanwhile, Indonesian strengthens students' mastery of scientific terminology and academic language skills. Although students still experience difficulties in consistently using scientific terms in Indonesian, bilingual instruction improves their understanding and connects learning concepts with their real-life experiences. The effectiveness of this strategy depends on teachers' ability to manage language switching in a structured and consistent manner.
