THE GROWTH OF BOTRYOCOCCUS BRAUNII MICROALGAE AS A LIPID PRODUCER IN A MIXED MEDIUM OF COCONUT WATER AND SEAWATER
ABSTRACT: Energy needs in fuel
sector tend to increase for supporting human life. Green microalgae
(Chlorophyceae) can be used as an alternative solutions for bioenergy.
Botryococcus braunii is lipid producer microalgae which can be processed
further into biodiesel. Microalgae growth medium such as Walne can be
substituted with coconut water that reducing economical cost. This research
aims to determine the growth of B. braunii using coconut water and its effect
on lipid production. The experiment conducted into five treatments of coconut
water consist of P0 (0%), P1 (10%), P2 (7.5%), P3 (5%), and P4 (2.5%) for five
days incubation and three repetitive step. Microalgae growth was calculated
according to cell count using hemocytometer. The results showed that 2.5%
coconut water substitution exhibited the best growth rate and lipid production,
i.e. the amount of 547 cells / ml and produced lipid level according to these
treatment increased 179% comparing with control.
