<![CDATA[This study aims to determine the effect of concentration and soaking time of aloe vera gel on the growth of robusta coffee cuttings. The research was arranged in a Randomized Complete Group Design (RAKL) with a factorial experiment (4x2) consisting of two treatment factors and repeated three times as a block. The first factor is the concentration of aloe vera gel with levels of 0, 20, 40, and 60%. The second factor is the length of soaking with levels of 5 and 10 hours. The results were analyzed using variance analysis, treatments that had a significant effect were further tested with Orthogonal Polynomial for the first factor and interaction and the Least Significant Difference (LSD) test for the second factor. The results showed that 40% aloe vera gel concentration produced the highest root dry weight. The treatment of aloe vera soaking time for 5 hours produced the longest root length. The interaction between aloe vera gel concentration of 20% and soaking time for 5 hours produces the longest root length.]]>
