Abstract

Microalgae is potential microorganism that grow in the water and has many benefits. Nannochloropsis sp. is a potential green algae that is widely used because it is easily cultivated and contains high nutrition. Nannochloropsis sp. commercially used as food ingredients, agricultural fertilizers, biomass energy, and the pharmaceutical industry. IAA and BAP are plant growth regulator that affect the growth and biochemical content of several species of microalgae. The Objectives in this study to determine the growth profile of Nannochloropsis sp. on culture media by treating a combination of IAA and BAP in various concentrations. The methods in this study are preparation and sterilization of tools and culture media, making Conway fertilizer, making stock solutions of IAA and BAP, determining starter time, and microalgae cultivation with a combination treatment of IAA and BAP. The variation of IAA and BAP concentrations consisted of 0; 0.1; 1; 10 mg/L. Data analysis is used quantitatively with a theoretical approach. We showed that the highest growth was in the treatment of IAA 0.1 + BAP 1 mg/L with an OD value of 1.358 at the end of the exponential phase. Our result showed that combination IAA and BAP can increase growth of Nannochloropsis sp.
