Green grass jelly (Premna oblongifolia Merr) is a plant that belongs to the Verbenaceae family with the Premna genus. The genus Premna
has about 200 species in the Verbenaceae family which are spread in tropical to subtropical areas such as Asia, Africa, and Australia. This
plant has potential as antibacterial, antipyretic, anti-inflammatory and antioxidant. This research was conducted to make an extract of
endophytic bacteria obtained from green grass jelly plants by maceration method. The extract obtained was tested for its antibacterial activity
by disc diffusion method. Extracts with the highest antibacterial activity were identified by FTIR and GCMS. The results showed that the
methanol extract of endophytic bacteria of green grass jelly plants had broad spectrum antibacterial activity because it was able to inhibit the
growth of Gram-positive bacteria (Bacillus subtilis) and Gram-negative bacteria (Pseudomonas aeruginosa). The results of FTIR and GCMS
showed that the active compounds contained in the endophytic bacteria of green grass jelly plants were thought to be Nerolidol compounds
or 3,7,11-trimethyl-1,6,10-dokatrien-3-ol which are secondary metabolites of the sesquiterpene alcohol group and play a role in as an
