Variation of Addition of Nutrients (Liquid NPK) in Microalgae Cultivation of Chlorella Sp.

Anshah Silmi Afifah

Abstrak

Nutrien merupakan faktor penting dalam pertumbuhan mikroalga. Amonia merupakan salah satu sumber nutrien yang paling disukai oleh mikroalga karena langsung dapat dimanfaatkan di dalam tubuh mikrolaga. Meskipun amonia paling disukai, namun keberadaannya dalam jumlah besar dapat berdampak buruk pada mikroalga. Sifat racun pada amonia dapat menyebabkan kematian pada mikroalga. Penelitian ini bertujuan untuk mencari komposisi penambahan nutrien yang paling sesuai pada proses kultivasi mikroalga. Variasi penambahan NPK cair (nutrien) yang dipilih pada penelitian ini yaitu 0 mL; 0,3 mL; 1 mL; dan 2 mL. Penelitian dilakukan dengan sistem batch teraerasi. Variasi yang dianggap paling sesuai untuk proses kultivasi mikroalga yaitu variasi penamabah NPK 0,3 mL.
