Studi Efektivitas Polinasi Jambu Air (Syzygium aqueum) Oleh Lebah Klanceng (Trigona spp.) Di Kebun Agrowisata Medan Istana Jambu, Sidirejo, Kabupaten Deli Serdang

Abstract

The use of Trigona sp. as a pollinator is one of the meliponiculture techniques to increase plant pollination. Klanceng bees (Trigona sp.) are a type of stingless bee that has an important role as a plant pollinator. This study aims to analyze the effect of Trigona sp. utilization on Syzygium aqueum fruit production. The study was conducted using a Randomized Block Design (RBD) with several treatments, the first being open and the second with the presence of Trigona sp. Observation parameters of this study included physical environmental factors, number of fruits, fruit weight, and fertilization duration. The results showed that treatment with the presence of Trigona sp. increased fruit production, although not significantly. Treatment with the presence of Trigona sp. produced the highest fruit weight, namely 270.00 ± 22.64a compared to the treatment without insect net cover 202.33 ± 14.18a. The percentage of water apple pollen obtained was 11.4% and 10.8%. The pollen collected consisted of 13 species, five of which were unidentified. Physical environmental factors observed showed that air humidity was inversely proportional to temperature and light intensity, indicating that bee visitation increased when temperature and light intensity were high and humidity was low. The results indicate that Trigona sp. plays a crucial role as a plant pollinator, increasing the productivity of cultivated plants.
