<![CDATA[Rhizosphere microorganisms (Plant Growth Promoting Rhizobacteria) play an important role in the plant nutrient cycle (fixation, solubilization, and nutrient supply), phytostimulator production, and plant resistance to pathogens. This study aims to identify the types of rice rhizosphere PGPR and examine secondary metabolite compounds from microorganisms that have the potential as elicitors. This study was conducted using observation and descriptive analysis methods by comparing inorganic and organic rice rhizosphere PGPR. Inorganic-rice rhizosphere soil samples were taken at Kebonsari, while organic ones were taken at Sumberjambe. The results showed that there were three types of bacteria, namely Azotobacter sp., Acetobacter sp., and Bacillus subtilis, for the inorganic rice rhizosphere, while in the organic rhizosphere there were also three types of bacteria, namely Bacillus aerophilus, Acetobacter sp., and Azotobacter sp. The GC-MS test results showed that the highest chemical compounds in the inorganic rice rhizosphere were acetic acid (CAS) and 2-pyrrolidinone, while the highest chemical compounds in the organic rice rhizosphere they were acetic acid (CAS) and 1,2,3-propanetriol. The 1,2,3-propanetriol compound (glycerol) has the potential to be an elicitor, while CAS is an antimicrobial compound.]]>
