In Indonesia, pulp industry has increased in the last two decades. In 1987, the pulp production capacity was only 0.5 million tons and increased to 6.5 million ton in 2007. Until now, 70% of pulp`s raw material came from natural forest. Wood as pulp`s raw material need to be reduced due to environmental concern and its availability continue to decline. Bagasse was lignoselulose which have potential as an alternative resource for pulp. Semi chemical process were pulpmaking process that combining chemical and mechanical process. This research was studied the physical properties of pulp with liquid to solid ratio (8/1, 10/1, and 12/1) and cooking time (2, 3, and 4 hours). The result shows that bagasse pulp have yield of 58.17% - 61.04%, lignin 18.27% - 21.34%. Yield pulp from bagasse has been achieved requirement for semichemical pulp.
