Patchouli oil is found in all vegetative part of Pogostemon cablin. Therefore, a high biomass is important to increase production of patchouli oil. Biomass production is on of plant growth indicator. Plant growth is a effected by genetic and environmental factor. Light intensity will effect to chlorophyl syntesis, photosynthetic rate, transpiration and hormonal balance. The aim of this research is to study effect of light intensity on biomass production of Pogostemon cablin. Design of research is CRD (Complete Randomized Design), with one factor which is light intensity. There were difference of light intensity that use as treatments. These are : 96 LUX, 340 LUX and 780 LUX. Each treatment was replicated five times. Result indicated that, light intensity affect biomass production of Pogostemon cablin. At light intensity of 96 LUX, biomass productions is the most optimum. An increase of light intensity, biomass production of Pogostemon cablin is reduction. Key words : biomass, Pogostemon cablin, light intensity.
