Jatiluih is a mountainous area with a very beautiful view International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 9 Number 8 (2020) Journal homepage: http://www.ijcmas.com Jatiluih Village is a cool, mountainous area in Penebel sub-district, Tabanan regency is a World Cultural Heritage area (World Herritage). This area is visited by many foreign tourists and is one of the famous tourism areas in Bali. The tourism object in this area is the natural beauty of terraced rice paddies and in the paddy fields there are many cowshed as a source of organic fertilizer, accompanied by a strong survival system of irrigation culture called Subak. The famous rice production in this area is brown rice, Jatiluih local brown rice is very popular with urban communities because besides it is organic, it also tastes fluffier and fragrant but if it is cooked it doesn't need to be mixed with white rice. Thus the improvement of brown rice cultivation should be carried out by involving growth-promoting bacteria (PGPR) whose application is to seed treatment in the proper carrier matrix, from the results of research obtained; A matrix containing with one PGPR bacterium can increase seed germination capacity, and brown rice plant height compared to control without PGPR. Organic fertilizer in the form of a matrix containing 4 types of bacteria Serratia marcescens, Achromobacter spanius, Providencia vermicola and Myroides adoratimimus can increase seed germination by 2 times, plant height and number of plant leaves 1.5 times compared to control. In terms of Stimulated the growth of rice plants, between the PGPR bacteria, it turns out that A. spanius and P. vermicola bacteria have a fairly good ability to increase the number of tillers in rice plants by 1.5 times the control, and it is expected that later production of brown rice will increase to 1.5 times as well. Likewise, rice plants that received PGPR bacteria produced higher, higher number of leaves and chlorophyll compared to controls that did not get PGPR bacteria. In the chromatographic image the GCMS results clearly showed the content of the compounds in the control ie plants without being given PGPR, the number of compounds was far less than in rice that was treated by PGPR bacteria. Rice with PGPR contains 9, 12, 15-Octadecatrienoic acid which is anti-bacterial and anti-fungal, while Neophytadiene and 2-Methoxy-4-vinylphenol can increase plant growth.
