This study aimed to determine the feasibility of Bacteria magz as alternative learning resources on the bacteria concept of senior high school. The method used in this research is a product feasibility test using a Likert scale. We used three experts to validate the Bacteria magz that have an expertises and experiences in learning media, bacteria concept, and alternative learning sources. The results of the expert test evaluation on the aspect of the media were 93,25%, while on the material aspect was 87,5%. The average value of the Bacteria magz as alternative learning sources was 90,37%. The Bacteria magz as alternative learning resources on bacteria concept was very suitable for ten grade students of senior high school.

Plant Growth Promoting Bacteria Rhizobacteria (PGPR) is one of the potential bacteria to enhance of Capsicum annuum through inhabitation the growth of pathogenic fungi. This study aimed to characterize PGPR in chili plants (Capsicum annuum). PGPR was isolated from the soil habitat of the red chili plant in Cilegon, Indonesia. Screening was then carried out with the dual culture method on Petri dishes and tested through in vivo method on the red chili plant. The selected bacteria were characterized morphologically, biochemically, and physiologically. The results revealed that there were 14 single isolates of bacteria from the roots of the red chili plants. The five single bacterial isolates, namely Azostobacter, Azospirillum, Pseudomonas, Serratia, and Beijerinckia have good potential as PGPR based on multiple culture screening by producing clear zones and positively effect the growth of chili plants.
