Abstract

Sugarcane is needed by the community so, that demand continues to increas in line with the increasing of Indonesia population. However, in fact sugar production decrease every year due to low sugarcane productivity.Given the importance role of sugarcane in the sugar industry, it necessary to carry out intensive continuous research to be able to help icrease productivity and alternate sugarcane cultivation. One of its latest berakthroughs is the administration of Rhizobacteria or known as PGPR and FAA in the sugarcane cultivation. This research was carried out from February untill May 2022 on the land of Jember State Polytechnic. The experimental design used factorial complete randomized design consisting two pactors and three tests. The first factorial is PGPR with concentration K0 (0%), K1 (5%), K2 (10%) and K3 (15%). The second factor is FAA with concentrations M1 (0%), M2 (1%l) and M3 (2%). The observed parameters are plant height, stem diameter, number of leaves, number of saplings, root wet weight, and rot dry weight. The data were analyzed with ANOVA, the real treatment was continued using duncan multiple distance test with a level 5%. The result showed that PGPR had no noticable effect on the parameters of plant height, stem diameter, number of leaves and number of saplings. PGPR concentration of 15% has an effect on the t wet and dry weight of root. Whereas the FAA had ni noticable effect on all observational parameters.
