Paddy cannot grow optimally on saline soil, one of which is due to the low production of plant hormones. One crucial plant growth hormone is auxin, the Indole Acetic Acid (IAA). The application of saline-resistant bacteria producing IAA can promote the paddy growth of saline fields. This study aimed to explore saline-resistant bacteria capable of producing IAA from paddy fields around Jetis beaches, Kebumen, Central Java, and to test them on hydroponic systems and to develop the bacteria into biofertilizer. The following steps were followed for this study, soil sampling, bacterial isolation, bacterial selection using saline medium, IAA production measurement, and screening in planta with hydroponic systems. The results showed that five isolates of saline-resistant bacteria produced IAA. Isolates JB 2 exhibited the highest IAA (26.34 ppm). Screening in planta showed that JB2 addition to the growing media had higher plant heights and weights.
