Pertumbuhan Spirulina Platensis Pada Media Dengan Konsentrasi Pome (Palm Oil Mill Effluent) Dan Pupuk Yang Berbeda
ABSTRACT
Spirulina platensis is a microalgae from Cyanobacteria that used as a natural food
in fish hatcheries and also as a food supplement for humans. This is due to its high
nutritional value, including 63-68% protein, 18-20% carbohydrates, and 2-3% fat.
Increased production of palm oil has serious side effects on the aquatic
environment due to the disposal of palm oil mill effluent (POME). Cultivating
algae using waste is an alternative. POME which is still rich in minerals such as
N, P, K are thought to be suitable for use as nutrients and media in plants. This
study aimed to determine the effect of POME with different nutrient variations on
the growth of these microalgae. This study used a randomized block design
(RBD) with 2 factors, namely factor A (POME concentration) which consisted of
3 levels of concentration, namely 20 ppm (treatment A1), 40 ppm (treatment A2),
and 60 ppm (treatment A3) and factor B (media) namely Walne (treatment B1),
and Guillard (treatment B2) with 3 repetitions. The results showed that the
addition of POME had positive effect on the growth of S. platensis. The higher the
POME concentration the better the growth rates obtained for both types of media.
For Walne medium, the best growth was obtained on day 10 of A3B1 treatment
(173.62 x 104 sins/ ml). Meanwhile, for Guillard medium, the highest growth was
achieved on day 8 of A3B2 treatment (205.07 x 104 sins/ ml).
