This study aims to determine the effect of different composition of BAP and NAA concentration added to Murashige and Skoog (MS) basic media on the in vitro multiplication of Indonesian ^Kepok^ banana variety. The research was conducted at the Tissue Culture Laboratory of the Bonto-Bonto Horticultural Plant Seed Center. A completely randomized design (CRD) was employed with two factors tested. Four concentrations of each BAP and NAA used were 0 ppm, 4.5 ppm, 5 ppm, and 5.5 ppm for BAP, and 0 ppm, 2 ppm, 2.5 ppm, and 3 ppm for NAA resulted in 15 composition of BAP:NAA in addition to control (without the hormones). The results show no interaction between the BAP and NAA treatments, BAP concentration of 5 ppm gave the best result on parameter time of shoots appearance (7.50 DAP). NAA concentration of 2.5 ppm gave the best results on root emergence time (8.61 DAP), plantlet growth time (11.72 DAP), number of roots (4.81 fruit) and root length (5.93 cm).
