Pengaruh Kompos Limbah Batang Pisang Terhadap Pertumbuhan Bibit Pisang Kepok Tanjung dengan Metode BIT (Bonggol Induksi Tunas)
Abstract
Kepok Tanjung banana is one of the banana varieties that has high economic value, but its development is still constrained by the availability of superior seeds. One alternative to propagating seedlings is the shoot induction hump (SIT) method by utilizing banana stem waste as organic compost. This study aims to determine the effect of banana waste compost on the growth of Banana Seedlings in Kepok Tanjung using the SIT method. The research was carried out descriptively at the experimental garden of Padang State University, Muaro Sijunjung, in June–November 2024. The tools used include polybags, scales, meters, and simple agricultural tools. The main ingredients consist of banana stem waste, dolomite, EM4, bran, soil, sand, and Kepok Tanjung banana humps. Five levels of compost dose treatment (0, 125, 250, 375, and 500 g per polybag) were tested with two replicas. The parameters observed included bud emergence age, number of buds, number of leaves, bud height, stem circumference, leaf width, and transplant age. The observation data are described descriptively and presented in the form of tables and standard deviations. The results showed that the administration of banana waste compost at a dose of 500 g of stems gave the best results in increasing the average amount of tuna (11.5 ± 2.12) compared to controls (8 ± 2.83). However, in the early phases, the addition of compost tends to slow the emergence of shoots due to the decomposition process and possible phytotoxic compounds. The conclusion showed that the application of banana stem waste compost on the Kepok Tanjung banana hump had a real effect on several vegetative growth parameters. A dose of 500 g of compost gives the best results for an increase in the number of shoots and the circumference of the bud stem, while a dose of 375 g is most optimal for tall shoots, and a dose of 250 g accelerates the life of transplantation.
