Abstract
Shorea javanica is a featured tree of Lampung Province. The dammar of this species, locally known as damar mata kucing (cat-eye resin). The population of S. javanica is mostly in Repong Damar and grows naturally in Bukit Barisan Selatan National Park. Within a decade, the damar mata kucing production was decreased. The threat of deforestation, land degradation, and the scarcity of regeneration were some of the causes. One of the important efforts that can be done was to procure quality seeds in the nursery. Knowledge of the health condition of seedlings in a nursery is very important in supporting the success of plant regeneration. Plant pests and diseases were one of the determining factors. This study aims to determine the health of S. javanica seedlings in South Lampung Permanent Nursery, which BPDASHL WSS manages. This seed health identification activity used the Systematic Random Sampling method with a sampling intensity of 10%. The samples obtained were carried out by identifying the type of damage, location of damage, and severity of all S. javanica seeds sampled using criteria and standards for crop assessment results according to the International Center's Environmental Monitoring standards Assessment Program (EMAP). Based on the result of the research that was observed, 75% of seeds are sick, and 25% of seeds are healthy. The intensity of total attack is about 75%, the intensity of pest attack is about 41%, and disease attack intensity is 32%, with the highest attack severity 30-39%. The results showed that the live percentage of S. javanica seedlings was 98% which was in the very good category.
