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
