Abstract

Biology learning at the senior high school level requires the support of interactive learning media to help students understand complex and abstract biological concepts. This study aims to analyze the need for interactive biology learning media among tenth-grade students at SMA Negeri 5 Tuban. A quantitative descriptive method was employed, using non-test data collection techniques in the form of questionnaires and teacher interviews. The instrument was developed using a Guttman scale (Yes/No) consisting of 15 items grouped into three aspects: learning media needs, accessibility and ease of use of learning media, and learning motivation and interest. The subjects of this study were tenth-grade students of SMA Negeri 5 Tuban. Data were analyzed descriptively to determine the level of students’ needs for interactive biology learning media. The results showed that the learning media needs aspect reached 92%, accessibility and ease of use reached 85%, and motivation and learning interest reached 99%, with an overall average of 92%, categorized as a very high level of need. These findings indicate that students have a very high demand for interactive biology learning media, highlighting the importance of developing interactive biology learning materials that align with students’ needs and characteristics.

Abstract

The increasing intensification of dragon fruit (Hylocereus sp.) cultivation is followed by an increase in disease attacks that have the potential to reduce plant productivity. This study aims to isolate, identify, and test the pathogenicity of bacteria that cause dragon fruit stem rot in Pematang Donok Village, Kepahiang, Bengkulu. Bacterial isolation was carried out from disease-infected stem tissue, followed by isolation purification. Bacterial identification was carried out based on colony morphology and Gram staining, while pathogenicity and hemolysis tests were carried out on potatoes and blood agar media, respectively. The data were analyzed descriptively qualitatively through observation of colony morphological characteristics and Gram staining, as well as pathogenicity tests on potatoes and hemolysis tests on blood agar. The isolation results obtained two bacterial isolates, namely isolates BBNK1 and BBNK2 with different colony morphology characteristics. Both isolates are Gram-positive bacteria with bacillus and coccus cell shapes. Pathogenicity tests on potatoes showed that both isolates were able to cause soft rot symptoms such as tissue softening, discoloration, and mucus formation compared to the control. Hemolysis tests showed that only isolate BBNK1 showed hemolytic activity with the formation of a clear zone around the isolate. The findings of this study offer foundational data to support future research on molecular identification and the development of more environmentally friendly and sustainable disease management strategies.
