IDENTIFIKASI KESEHATAN BIBIT BALANGERAN (Shorea Balangeran K) DI PERSEMAIAN Health Identification of Balangeran (Shorea Balangeran K) seeds in nursery

Balangeran (Shorea balangeran Korth.) is a genuine type of peat swamp plant that has rapid growth so it has the potential to be developed in the framework of peat swamp forest development. The success of planting can not be separated from the provision of good quality seeds in the nursery. Pests and diseases are one of the critical success factors in the cultivation of this plants. This study aims to identify the causes and types of damage that attacked balangeran seedlings, analyzing pest and disease attacks on balangeran seedlings.The object of this research is balangeran seedlings that come from seed (generative) which has 6 months old in nursery Tumbang Nusa Central Kalimantan. The data were obtained through field observation by observing the sample of balangeran seed.The next data are processed according to standards and criteria of crop research results based on  the standards and the codes of the Environmental Monitoring and Assessment Program (EMAP). Based on the result of the research,  from 220 seed balangeran that was observed 164 seeds (74,24%) are sick and 56 seeds (25,45%) are  healthy. The intensity of total attack is about 74,54%,  the intensity of pest attack is about  42,27% and disease attack intensity is 39,54% with highest attack severity 20-29%.Keywords: Enviromental Monitoring and Assessment; the health of the seed; BalangeranBalangeran (Shorea balangeran Korth./Burck) merupakan jenis asli tanaman rawa gambut yang memiliki pertumbuhan cepat sehingga memiliki potensi untuk dikembangkan dalam rangka pembangunan hutan rawa gambut.
