ATTACKING OF Ficus spp STRANGLER ON OIL PALM PLANTATION; SRIWIJAYA UNIVERSITY CAMPUS AREA CASE
Abstract
Palm oil (Elaeis guineensis Jacq.) is an important commodity in Indonesia, but the presence of hemiepiphytes of the genus Ficus can inhibit its growth and productivity through a strangulation mechanism. This study aims to identify Ficus species that attack oil palm, evaluate the attack rate, and analyze the influence of stem diameter on plant health. The research was conducted in the roadside area of Sriwijaya University, Indralaya, using a descriptive survey method. The results showed that three species of Ficus attacked oil palm: Ficus benjamina (415 individuals), Ficus retusa (2 individuals), and Ficus sundaica (1 individual). The attack rate reached 24%, belonging to the category of light attack, with 2% of the plants experiencing death. Most Ficus have a small diameter (64.11%) in the range of 1 - <10 cm, with an estimated lifespan of ±5 years, while some individuals >35 cm are estimated to be ±35 years old. The Ficus attack has the potential to reduce palm oil productivity by up to 6% of total production. The results of the study show that Ficus hemiepiphyte has a significant impact on oil palm crops and its population can continue to increase if not controlled.
