Abstract

The nutmeg tree (Myristica fragrans Houtt.) is a tree that produces fruit and seeds that have high economic value.The productivity of nutmeg fruit and seeds at the area cultivated by the Harapan Baru III Forest Farmer Group in the Wan Abdul Rachman Grand Forest Park has decreased, allegedly due to pest and disease attacks.Therefore, research was conducted at the forest farmer group's cultivated area to determine the types of damage as signs of pest and disease attacks, analyze the area of attack and the level of attack, and analyze the distribution of pest and disease attacks on nutmeg trees.Data collection was carried out through vegetation surveys with systematic sampling and a sampling intensity of 2.8%.Twenty nested sample plots were arranged in a nested rectangular plots design.The data collected includes the species of trees that make up the forest garden stands and the types of damage that occur to the nutmeg tree organs.The results of the research showed that there were 11 types of damage as signs of pest and disease attacks, namely open wounds, necrosis, leaves with holes, leaves curl, black spots on the leaves, yellow spots on the leaves, leaf rust, insect bites on the leaves, brown spots on the fruit, black spots on the fruit, and fruit cancer.The extent of attack reached 100% of the 66 individual nutmeg trees that was observed.However, the level of pest and disease attacks on the nutmeg tree population is in the very light category (average percentage of tree organ damage is 5.68%).The distribution of signs of pest and disease attacks on nutmeg trees was found in all sample plots.
