Abstract

This study aims to analyze the level of junior high school students' knowledge of the Nature of Science (NOS) based on school type (public and Islamic junior high schools) and gender. This study is a descriptive quantitative research involving 180 students with details of 81 students from public junior high schools and 99 students from Islamic junior high schools determined by random sampling technique. The sample consisted of 104 female students and 76 male students. The research data were collected using an instrument in the form of a questionnaire that has been tested for validity and reliability based on a Likert scale developed based on NOS aspects. The results showed that (1) there was a significant difference in the understanding of NOS between students of public and Islamic junior high schools, where students of public junior high schools had a higher level of understanding (good category) than students of Islamic junior high schools (moderate category); (2) there was no significant difference in the understanding of NOS based on gender.

Abstract

This study aims to determine the effect of cocopeat and hydroton growing media on the growth of tomato plants (Lycopersicum esculentum Mill.) in polybag cultivation systems. The research used an experimental method with a Completely Randomized Design (CRD), comprising six treatments and four replications. Observed parameters included plant height, leaf number, root length, and fresh and dry plant weights. The results showed that treatment P5 (50% soil + 50% hydroton) yielded the best outcomes across most parameters, such as plant height (47.75 cm), leaf number (12.50), root length (24.75 cm), and fresh stem weight (24.75 g). Conversely, treatment P2 (100% cocopeat) showed the lowest growth results. The study concludes that a combination of soil and hydroton is the most effective growing medium for supporting tomato plant growth. Further research is recommended through the generative phase to evaluate yield effects.
