Abstract

The use of biological agents such as Bacillus sp. bacteria has begun to be widely used by farmers as a new form of control. Bacillus sp. needs to require special methods in its application because it has certain living conditions, and Bacillus sp. is vulnerable to environmental pressures. Bioencapsulated formulation in the form of granules is considered effective as a form of bacterial application in soil because it is able to protect Bacillus sp. and maintain survival. This study aims to determine the best concentration of sodium alginate in maintaining the viability of Bacillus sp. at the in vitro stage and to see changes in the size of the beads. The beads were made using extrusion method by combining Bacillus sp. suspension and sodium alginate suspension at 1%, 1.5%, and 2% concentration. The concentration of sodium alginate was not a major factor in changes in bead size and viability test results experienced significant changes in each observation. 1.5% and 2% concentrations can reach the highest viability value of 3x106 CFU/mL and decreased during 1 month of observation. Changes in bead size and viability were caused by the alginase enzyme produced by Bacillus sp.

Abstract

Streptomyces sp. and Trichoderma harzianum is a biological agent that is effective in controlling Colletotrichum capsici, the cause of disease in chili plants. Different growing media can affect the growth and activity of these two microorganisms. This study aims to evaluate the growth of Streptomyces sp. and Trichoderma harzianum on various media, namely rice washing water, coconut water, and sugar potato extract. The research phase includes growing media test, effectiveness test of Streptomyces sp. and Trichoderma harzianum in chili peppers, and effectiveness test of Streptomyces sp. and Trichoderma harzianum on chili seeds. The results showed that the medium of rice washing water is more suitable for Streptomyces sp., coconut water media is more suitable for Trichoderma harzianum, and rice washing water media is more suitable for the combination of the two biological agents. Optimal growth in these media affect the effectiveness of biocontrol in suppressing the severity of anthracnose disease in chili.
