Abstract

Kepok tanjung banana (Musa paradisiaca var. balbisiana) is a priority commodities that has challenges in conventional seedling development because it is susceptible to disease. This study aims to evaluate the effect of non-toxic microbial inoculants isolated from tropical rainforest soil on the growth of Kepok tanjung banana seedlings in tissue culture seedlings. The method used was an experiment with a completely randomized design (CRD) involving a control and various microbial inoculation treatments (bacteria, fungi, and microbial consortium). Results showed that treatments SP8 and SP3 (bacteria) gave the highest stem height, 88.5 cm and 87.0 cm, respectively, and the largest stem diameter (SP3: 27.2 mm). In addition, the highest leaf length was found in SP8 (49.0 cm) with greener leaf color (score 5). All microbial treatments showed non-toxic results, with media pH remaining stable (6.3-6.6). The bacterial and fungal consortium (KJB) treatment, showed better results than single inoculants in improving nutrient availability and pathogen control. This research supports sustainable agriculture and contributes to the SDGs, particularly SDG 2 (Zero Hunger) and SDG 12 (Responsible Consumption and Production) with an environmentally friendly solution for the efficient and sustainable propagation of banana seedlings.
