Abaca is a type of banana plant used as paper material for securities industries, therefore, it has high economic value. This study therefore aims to determine the effect of Benzyladenine (BA) and thiamine in the induction of Abaca banana shoots in vitro. It was conducted at the Biotechnology laboratory of UPN "Veteran" Yogyakarta with the laboratory experiments arranged in a 2-factor Complete Randomized Design. The first factor in the experiment was the concentration of BA (3 ppm, 4 ppm, 5 ppm) and the second was the concentration of thiamine (10 mg/L, 20 mg/L, 30 mg/L). The results showed an interaction with plantlet height parameters in the treatment of BA 3 ppm and Thiamin 20 mg/L. 5 ppm Benzyl Adenine resulted in the highest yields on shoots length, the number of leaves, and fresh weight plantlets.10 mg/l Thiamine resulted in highest yields on shoots length, number of leaves, and fresh weight plantlets.
