Pengaruh Pupuk Tauge Kacang Hijau (Phaseolus Radiatus) Terhadap Kepadatan Dan Kandungan Karotenoid Dunaliella Salina
Abstract
Dunaliella salina is a group of green algae that produces pigment (chlorophyll and carotenoids) and used as live feed in hatchery especially for marine commodities. Nitrogen and phosphorus are needed by D. salina can be obtained from P. radiatus extract. The purpose of this research is to know the effect and optimal dose of P. radiatus extract at media culture toward density and carotenoid content of D. salina. The research was conducted on March-May in the Natural Feed Laboratory, BBPBAP Jepara Central Java. The research method was used completely randomized design. The treatments used is P0 (control) (Walne 0,5 mL/L), and P. radiates extract is treatments P1 (60 mL/L), P2 (120 mL/L), P3 (180 mL/L), with 3 replicates. The results showed that the P. radiatus extract as a media culture gives an effect on the density and carotenoid content of D. salina. Phaseolus radiatus extract showed the best density and carotenoid content at dose 60 mL/L. The amount of density in the exponential phase was 476.67 x 104 cells/mL with a carotenoid content of 0.967 µg/mL.
