Abstract

The use of antimicrobials from plant extracts has not been used optimally to control pathogenic agents in dragon fruit plants. The purpose of this research was to determine the antimicrobial activity of zodia (Evodia suaveolens) leaf extracts on pathogenic agents of dragon fruit plants in vitro. The research method is laboratory research with Completely Randomized Design (CRD). The antimicrobial concentrations of zodia (E. suaveolens) leaf extract used six types including 50%, 60%, 70%, 80%, 90%, and 100% with four replications. The research sample was the leaf of zodia (E. suaveolens), Pseudomonas aeruginosa and Fusarium oxysporum strain Malang. Test the antimicrobial activity of zodia (E. suaveolens) leaf extracts on the growth of P. aeruginosa and F. oxysporum using the disc-diffusion method and wells method. The research instrument was used the observation sheet of the diameter of inhibition zone indicated by the clear zone. The diameter of inhibition zone data were analyzed using the One Way ANOVA test. The results showed that the antimicrobial activity of zodia (E. suaveolens) leaf extract significantly inhibited the growth of P. aeruginosa and F. oxysporum (P <0.05). These results recommend zodia (E. suaveolens) leaf extract as an antimicrobial agent for dragon fruit plant pathogens.

Abstract

The Microbiology learning at the Department of Biology Education IKIP Budi Utomo not used learning media that integrates digital, technology, and humans to help students understand the concept of microbiology. The purpose of this study was to determine the responses of students and lecturers to multimedia with STEM education (M-STEM) in microbiology learning. The research method is a quantitative descriptive research method through survey techniques with a sample of 43 students and 4 microbiology lecturers at the Department of Biology IKIP Budi Utomo. The research instrument wasa questionnaire consisting of 40 questions for students and 25 questions for lecturers. The results showed that students strongly agreed to use multimedia (62.8%), students were more interested in multimedia (25.6%), students rarely use STEM education (60.5%), students agree that microbiology learning uses the STEM education (58.1%), students are very interested in multimedia with STEM education (90.7%), students agree that multimedia with STEM helps them to understand the concept of microbiology (58.1%), lecturers strongly agree to use the STEM education (100%), and lecturers strongly agree to use multimedia (100%). This study concluded that students and lecturers need M-STEM in microbiology learning at the Department of Biology Education IKIP Budi Utomo.
