Abstract

Epiphytic weeds living on oil palm trunks will complicate harvesting activities. In addition, the presence of this weed can increase the risk of accidents being hit by fruit during harvesting. The objective of this research was to obtain herbicide and its efficient concentrations to control epiphytic weeds using root infusion method. The research was arranged in a single factor completely randomized design (CRD) with five treatments and five replications. Active ingredients of herbicide that used were methyl metsulfuron at a concentration of 20%, 30%, and 40%, glyphosate 30%, and triclopyr + diesel fuel at a ratio of 1:19. All treatments except triclopyr were diluted in 100 ml water for each epiphytic weed. Weed mortality rate (%) was observed every week for one month. The results showed that a solution of 30% methyl metsulfuron herbicide in 100 ml of water and 30% glyphosate in 100 ml of water was the most optimal treatment in controlling epiphytic weeds. Cutting the entire suction root of epiphytic weeds can increase the chance of weed mortality.

Abstract

Harvesting fresh fruit bunches (FFB) is an important activity in the oil palm plantation industry. This study aimed to analyze the potential content of palm oil at the level of loose fruit that falls on the oil palm circle. Observations were made on five fresh fruit bunches with criteria 1, 3, and 5 respectively loose fruit per bunch that falls on the oil palm circle from oil palm trees that were 22, 16, 12, and 7 years old. All sample fresh fruit bunches were analyzed for potential oil to bunch ratio and oil to wet mesocarp ratio in the analytical laboratory of Bumitama Gunajaya Agro. Content of oil to wet mesocarp ratio in loose fruit 1, 3, and 5 were 48.50%, 51.98%, and 53.21% respectively. While the content of oil to bunch ratio in loose fruit 1, 3, and 5 were 24.19%, 25.52%, and 25.71% respectively. Based on variable of oil to wet mesocarp ratio, the highest potential for oil content occurs in ripe palm fruit with a level of five loose fruit   per bunch that falls on that oil palm circle. Five loose fruit per bunch on the oil palm circle can be used as an indicator for harvesters to harvest ripe fruit with optimal oil content.
