Endophytic bacteria derived from plant roots have the potential as a trigger for germination and plant growth with the ability to produce phytohormone, nitrogen binding, as a phosphate solvent, and are able to produce various secondary metabolite compounds that play a role in increasing plant resistance to various disease disorders. This study aims to determine the effectiveness of endophytic bacteria in spurring aromatic local rice seed germination so that it is expected to provide information for relevant parties in efforts to support environmentally friendly sustainable agriculture. The test method carried out by immersing the seeds in a suspension of endophytic bacterial isolates with a bacterial density of 108 CFU mL-1 for 24 hours as a comparison (control) used seeds soaked in sterile aquadest. Endophytic bacterial isolates used were derived from the roots of aromatic local rice plants in Central Sulawesi that had been isolated and tested for their ability in previous studies. Ten isolates were found, namely RKBK1, RKBK4, RKBL6, RKBU1, RKBU5, RKGU6, RKGU11, RKLE3, RKLE6 and RKLE7. The results showed that all endophytic bacterial isolates had the potential to promote rice seed germination. The average percentage of normal sprouts produced is = 84%. RKGU 11 isolates gave the best results on observations of the percentage of normal sprouts of 97.33%, the length of the plumula at 7.67 cm and the length of the radicles at 9.80 cm.
