Pengaruh Konsentrasi Nitrat Dan Fosfat Terhadap Biomassa Spirulina Platensis Pada Skala Indoor

---

One of the microalgae that is widely used in the industrial world is
Spirulina platensis which has high nutritional content of protein, fatty acids,
vitamins and antioxidants. In its growth, this microalgae requires media and the
addition of macronutrients nitrate and phosphate which greatly affect the growth
and productivity of S. platensis biomass. This study aims to determine the effect
of nitrate and phosphate concentrations on S. platensis biomass on an indoor scale
and to determine the optimal nitrate and phosphate concentrations to achieve
maximum biomass. This research was conducted in August 2020 as an
experimental method, with culturing S. platensis with the addition of different
concentrations of nitrate and phosphate. The design used in this study was a
Completely Randomized Design consisting of 5 treatments that is 0 ppm, 10 ppm,
20 ppm, 30 ppm, and 40 ppm, each treatment with 3 repetitions. The source of
nitrate and phosphate used is NPK. Water quality parameters during culture with
temperatures ranging from 29-30oC, salinity 25-26 ppt, and pH 8. The optimal
concentrations of nitrate and phosphate to achieve the maximum biomass is in
treatment C (30 ppm) with a total of biomass 0.43 g. Whereas in treatment D (40
ppm) the biomass did not show a significant increase because the dose was too
high with a total of biomass only 0.299 g.
