Sengon is a multi-use type, its leaves are used for animal feed because they contain high protein, and are also used for green fertilizer because sengon roots contain many root nodules that can be symbiotic with Rhizobium bacteria which provide nitrogen in the soil. Sengon wood has high economic value because it has durability class IV-V and strength class V-VI, so that sengon wood is widely used as the basis for carpentry or building wood. This study aims to calculate the percentage of sea sengon plant health and analyze the health conditions of sea sengon plants. The method used in this study is the Scoring Method by determining the attack score on the sea Sengon seedlings. The results of this study indicate that the percentage of health of sea sengon plants is 66,95 % and is damaged by a percentage of 33,05%. Based on the damage produced there are pests, diseases, pests and diseases. Can be seen in the condition of sea sengon seedlins which are attacked by pests with a percentage of 2,55 %, attacked by a percentage of 19,1 %, attacked by pests and diseases with a percentage of 11,4 % there is type of damage to the leaves such as lumpy leaves, leaves with holes, leaves yellowing color chages, leaves have spots, leaves fall out and wither. |
