Abstract

The objective of this research is to examine the impact of the Discovery learning model, supplemented by evolution films, on concept mastery and scientific literacy in the classroom. This study involved class XII students from SMA Negeri 1 Ngaglik, Sleman Yogyakarta. The research sample was determined using a purposive sampling technique, yielding two classes: 1 class as the control class and the other as the experimental class. The data was collected using a pretest, posttest, and final assessment. Data was analyzed using SPSS 27. The research results show that the value of Asymp. Sig. (2-tailed) from the Mann-whitney test, mastery of experimental class concepts was <0.001 (p<0.05) and scientific literacy was 0.032 (p<0.05), indicating that the application of the discovery learning model assisted by evolutionary videos had an effect on increasing the mastery concepts and scientific literacy of students at Ngaglik 1 State High School.

Abstract

The hydroponic technique is a solution for agricultural activities that do not require a large area of land because it does not require soil as a growing medium but uses water. Rockwool is a commonly used seedling medium in hydroponics. Organic waste has the potential to be used as seedling media because it contains many substances and microorganisms that are beneficial for plant growth. This study aimed to determine the effectiveness of banana fronds, sugarcane stalks, and orange peel waste as seedling media for lettuce (Lactuca sativa L.) plants that are environmentally friendly in hydroponics. This study used a Non-Factorial Completely Randomized Design (CRD) with five treatments and four replications, where each replication consisted of 20 samples. The results of DMRT analysis showed that various compositions and types of seedling media had different effects on each characteristic, namely seedling height, number of leaf blades, germination percentage, water absorption, and the level of consistency of the mash. Banana fronds, sugarcane stalks, and orange peel waste in the ratio of 1:2:1 have the potential to be an environmentally friendly seedling media for hydroponic lettuce cultivation.
