Pulp and paper sludge contains cellulose which has a possitive potential as compost material. This study aims to examine responses of jabon ( Anthocephalus cadamba ) seedlings planted in Ultisol and peat media with addition of pulp and paper sludge compost. Before composting, the sludge was air drained to reduce water content from 80.92% to around 60-70%. Bio decomposers consist of a combination of P. citrinum and P. oxalicum with a density of 10 7 ml/spores were inoculated to the sludge and incubated for six months. Compost of sludge was added to grow media (ultisol and peat) with doses equal with 2, 4, 6, 8, 10, 12, 14 and 16 (ton/ha). Control treatment consists of fertile soil as a negative control, and Ultisol and peat soil with chicken manure compost addition as a positive control. Seedlings height and diameter measurement were held for six months. Both in ultisol and peat media, the addition of chicken manure compost was better in raising seedlings height and diameter. However, the sludge compost addition in peat media was better in raising the seedlings biomass than those added with the chicken manure compost.
