Abstract

This study aims to investigate the reciprocal impact of Vitamin B1 and rice washing water usage, as well as the utilization of lumber + coconut husk + moss medium, to identify the most effective medium for expediting the growth of Vanda tricolor seedlings after acclimatization, as well as determining the optimal application method for Vitamin B1 or rice washing water to enhance their growth. This study is a field experiment that uses a complete factorial randomized block design, comprising 2 elements. The primary determinant is the medium composition, consisting of either lumber or a combination of lumber, coconut husk, and moss. The secondary component is the nutrient source, which can be water, vitamin B1, or rice- washing water. The research findings indicate that the growth of Vanda tricolor after acclimatization is influenced by both the kind of medium and nutritional source, specifically to disease attack parameters. Lumber is the preferred medium for promoting the growth of Vanda tricolor after it has adapted to the conditions on the slopes of Mount Merapi. Vitamin B1 is the suggested nutritional supply to enhance the growth of Vanda tricolor after it has adapted to the conditions on the slopes of Mount Merapi.
