Abstract

The Chaetoceros is a genus of microalgae that belongs to the diatom group with the class of Bacillariophyceae. These microalgae are often found in Indonesia marine waters. Chaetoceros calcitrans is a species of microalgae that is widely used as natural feed in the fisheries sector because it has a high nutritional content. The cultivation process of C. calcitrans is influenced by physical and chemical factors. The aim of this research was to determine the nutritional content of C. calcitrans in culture media with different fertilizers. The Treatment fertilizers were (P1) = Urea (0.1 g/L); Silica Fertilizer (0.015 g/L), (P2) = NPK (0.1 g/L); Silica Fertilizer (0.015 g/L), (P3) = NPK (0.1 g/L); Urea (0.1 g/L); Silica Fertilizer (0.015 g/L), Control (P0) = Diatom Fertilizer (1 ml/L), Thiamine (1 ml/L), Silica (1 ml/L) and Vitamins (1 ml/L). Proximate analysis was used as a method to determine the nutritional content. The results of the study showed that the carbohydrate content of C. calcitrans was P0 67.48%, P1 66.80%, P2 55.37%, and P3 56.28%. The highest moisture content was found in P2 treatment 14. 67%, the highest ash content in P3 was 0.6%. Meanwhile, the fat content for P0 had the lowest value 2.13%, and the highest fat content in P2 was 8.07%. The protein content in all treatments had almost the same value, it was around 21%. The study demonstrates that fertilizer type significantly alters the biochemical composition of C. calcitrans, with agricultural fertilizers promoting lipid accumulation, while the protein content remained consistently high across all treatments.
