This study aimed to determine the utilization of research results of the selection of marine fungi for milkfish ("Chanos chanos") feed. The study was conducted in stages, starting with identifying the issues in the learning activities of biotechnology concepts, followed by experiments to identify research methods and products, selecting an adaptation of research findings as the learning source content, and application and development of research findings as learning. The data and information were gathered through an interview grid and a questionnaire, and the findings of the surveys were then analyzed qualitatively. The results of a selection study of marine fungi from Dua Island, Banten, Indonesia as feed for milkfish related to basic competency (KD) 3.10 and 4.10 can be used as learning resources as digital magazines for class XII high school students. Thus, media can help student in learning process.

The challenge for a teacher in the learning process is to engage students with the subject and help them comprehend biology using creative and efficient learning media. The research aims to provide information on the postharvest fungi as well as their role as contaminant fungi in Bantenese emping melinjo chips as the contents in the poster as learning media and to determine its effect on assisting student knowledge and critical thinking skills. The Research and Development was conducted using the ADDIE model. The information was gathered through the use of interview guidelines, validation sheets, and students' response questionnaires. The research findings informed that a total of 35 species of post harvest fungi have been successfully isolated from eight different locations in Banten Province. The evaluation results of the poster as learning media showed that it was considered very valid by media and material validators. Student responses showed that the developed poster was categorized as very feasible media. The student knowledge and critical thinking skills achievement facilitated by the poster as e-learning media was significantly higher compared to another class. The produced poster was found to be suitable to be used as e-learning media in the Biology subject.

Pandeglang is one of the banana producer regencies of Banten, Indonesia, that produce 924 tons per year. However, information regarding the diversity of banana germplasm in this region is unavailable. This study explored districts Cadasari, Banjar, Jiput, Labuan, and Menes. Morphological characters were noted and used to identify the cultivars, subspecies, or varieties. In total, 22 accessions were collected from 22 collection sites. Based on morphological characters, we described 14 banana accessions of 10 cultivars, three accessions of wild Musa acuminata and one of Musa balbisiana. Considering its genome composition, five genome types we described among these banana cultivars, i.e., AA (divided into AA and AA wild), BB, AAA, AAB, and ABB. In this study, we did a principal component analysis and saw that AA wild and AAB were clearly separated, but the other genome types were clustered partially or included in one cluster. Our study expands the information on banana diversity in Indonesia. Further study on the potential of this banana germplasm to be used as a genetic resource to find resistance to banana diseases is needed. [ABSTRACT FROM AUTHOR]
