Kultur Biofilm Spirulina sp. dengan Flash chamois synthetic Sebagai Substrat
Microalgae in aquaculture are mainly used as natural food for fish and shrimp larvae and as the main food in shellfish cultivation. In addition, microalgae flour has also begun to be tested for its use as a protein source in artificial feed. The challenges in microalgae biomass production were harvest efficiency and the high amount of water demand. One of the efforts to increase biomass production and to minimize water use was by culturing microalgae biofilms. This research was conducted at Politeknik Kelautan dan Perikanan Bone by examining the use of substrate to grow Spirulina sp. biofilm. The study was conducted following a completely randomized experimental design with two treatments, such as culture with the substrate in the form of synthetic flash chamois and culture without substrate (conventional). Spirulina sp. was cultured for 7 days and its productivity was measured based on dry weight. The results showed that the dry weight of Spirulina sp. cultured with substrate and without substrate was significantly different (P <0.05). The results of this study indicated the potential use of flash chamois synthetic as substrate in the culture of Spirulina sp. biofilm.
