One of the efforts to increase the growth of pepper cuttings (Piper nigrum L.) and encourage environmentally friendly and sustainable agricultural development (SDGs) is by utilizing Plant Growth Promoting Bacteria (PGPR). This study aims to determine the effect of PGPR concentration on the growth of pepper cuttings. The research design used in this study was a Completely Randomized Design with four PGPR concentration treatments, namely 0 g.L-1, 0.5 g.L-1, 1.0 g.L-1, 1.5 g.L-1. Data obtained from observations and measurements were analyzed statistically using analysis of variance and Duncan's multiple range test. The results showed that PGPR treatment can increase the vegetative growth of pepper cuttings. PGPR concentration of 1.0 g.L-1 gave more effective and significant results compared to treatment without PGPR in stimulating the growth of shoots, leaves, and roots of pepper cuttings.
