The Development of Tubular Photobioreactor for Spirulina Paltensis Cultivation

Abstract

The purpose of this research is to build a 105 liter Tubular Photobioreactor and to cultivate Spirulina Platensis. The condition includes Zarrouk Medium and air velocity at 0.07 meters per second. The duration between the dark and light was set to 16:8 hours, the light intensity of 8,900 lux , ambient temperatures between 35-40 ° C, and pH set between 8.5 to 11. The Growth behavior of algae was measured by the Dry weight Determination for the possibility amount of biomass. This can be done through the comparison between an Optimal Tubular Photobioreactor and the based Tubular Photobioreactor. The result showed that the model created of Optimal Tubular Photobioreactor boost up the cultivation of Spirulina Platensis at 25% over the based tubular
