Abstract

Java long pepper (Piper retrofractum Vahl) is classified as a medicinal and spice plant. It can be propagated through seeds, climbing branch cuttings, ground branch cuttings, and fruit branch cuttings. The success rate of propagation using climbing branch cuttings is around 75%, ground branch cuttings 66%, and fruit branch cuttings 38%. The use of growth stimulants and fertilizers also plays an important role in the propagation process. This study aims to analyze the growth response of Java long pepper seedlings using biological resources such as rice washing water, Jakaba, and fermented cow urine. The study employed a Completely Randomized Design with DMRT for data analysis. The results showed that the application of these biological resources had a significant effect on the growth response of Java long pepper seedlings in all treatments, influencing parameters such as plant height, number of leaves, number of nodes, internode length, and root length, with the use of auxin hormone, Jakaba, fermented cow urine, and rice washing water.
