| Summary: | <p>This experiment was conducted to compare the effectiveness of inorganic fertilizer and chicken manure on population growth and nutrient content of <em>Spirulina platensis</em>. It was found that <em>Spirulina platensis</em> cultured in inorganic medium reached a maximum population on day-9 with a density of 614.77x10<sup>3</sup> Sin/ml, containing 56.39% of crude protein and 17.92% of lipid. On the other hand, <em>Spirulina platensis</em> cultured in 250 ppm of chicken manure reached a maximum population on day-4 with a density of 434.32x10<sup>3 </sup>Sin/ml, containing 45.39% of crude protein and 12.50% of lipid.</p> <p>Keywords: spirulina, <em>Spirulina platensis</em>, culture, inorganic fertilizer, chicken manure, population maximum</p> <p> </p> <p>ABSTRAK</p> <p>Penelitian ini dilakukan untuk membandingkan efektivitas pupuk inorganik (urea, TSP dan ZA) dan kotoran ayam terhadap pertumbuhan dan kandungan nutrien <em>Spirulina platensis</em>. Hasil penelitian menunjukkan bahwa <em>Spirulina platensis</em> dikultur menggunakan pupuk inorganik mencapai puncak populasi pada hari ke-9 dengan kepadatan 614,77x10<sup>3</sup> Sin/ml, mengandungkan protein kasar 56,39% dan lemak 17,92%. Sementara itu, <em>Spirulina platensis</em> dikultur menggunakan kotoran ayam 250 ppm mencapai puncak populasi pada hari ke-4 dengan kepadatan 434,32x10<sup>3</sup> Sin/ml, kandungan protein kasar 45,39% dan lemak 12,50%.</p> <p>Kata kunci: spirulina, <em>Spirulina platensis</em>, kultur, pupuk inorganik, kotoran ayam, populasi maksimal</p> |
