Abstract

Genetic diversity of Robusta coffee plants (Coffea canephora) can be known by identifying morphological characters. Local Robusta coffee is found in the Karang Mountain area. This study aims to determine the diversity of morphological characters and characteristics that distinguish between plant samples in the Karang Mountain area. This research is an exploratory and descriptive survey with a purposive sampling technique. The variables observed were vegetative and generative morphological characters of plants. The results showed that there was a diversity of plant morphological characters and there were characteristics that distinguished between Robusta coffee plant samples in the Gunung Karang area. Vegetative characters include plant stature, plant height, plant shape, stem stature, stem branching shape, stipule shape, young leaf color, leaf shape, leaf tip shape, leaf edge shape, leaf length, and leaf width. Generative characters include fruit color, fruit shape, fruit width, fruit thickness, seed width, seed thickness, seed color, and seed shape.

Abstract

This research aimed to evaluate the effects of organic material concentrations and soaking durations on the growth of var. Citra water apple (Syzygium aqueum) stem cuttings. The experiment was conducted using a factorial Randomized Block Design with two factors: organic material concentration Z1 (100% coconut water), Z2 (10% aloe vera extract), and Z3 (100% coconut water + 10% aloe vera extract), as well as soaking durations P1 (8 hours), P2 (10 hours), and P3 (12 hours). These factors produced 9 treatment combinations, each repeated 3 times, resulting in 27 experimental units. Observed parameters included sprout emergence time, number of sprouts, sprout height, number of leaves, number of roots, root length, and survival rate. The research indicate that the combination of young coconut water and aloe vera extract (Z3) significantly influenced the number of leaves at 4 Weeks After Planting (WAP), with an average of 11,44 leaves. The soaking duration had a significant effect on sprouting time, with the 8-hour soaking treatment (P1) resulting in the earliest sprouting at an average of 7,16 days. Additionally, the number of shoots at 3, 4, and 5 WAP in the P1 treatment had average heights of 9,94 cm, 10 cm, and 8,33 cm, respectively. The number of leaves at 4 WAP in the P1 treatment averaged 11,55, while the number of roots at the end of the study averaged 10,83 in the P1 treatment. Keywords: Stem cuttings, Var. Citra, water apple, coconut water, aloe vera, growth regulators, soaking duration.
