Production of biomass and protein of freshwater microalgae cultured in fish farm wastewater / Siti Aisyatul Humairah Abdullah

By follow the Final Year Project Programme, our groups which consists by 4 members decided with supervisor to choose Cultivation of Microalgae as our FYP research. Based on my research, our purpose in this report to talk about result that we produce of biomass and protein of microalgae cultured in fish farm wastewater. We applied fish farm wastewater as media replaced regular media to cultivate microalgaes. Follow sustainable development program, our research related to make sure our product and application doesn't affect to environment give benefits to biodiversity. As a future engineer, I take responsible to make sure how I can produce a product saving cost and environmentally friendly. We use 4 main components, which is Fish farm wastewater, 3 types of microalgae, Chlorella Vulgaris, Spirulina, and Nannochloropsis, and commercial media( Urea and NPK) We use several methods, example like HACH method for method analysis, and method cultivation microalgae that we regular found in journalists, based on discussion we decided to make ratio 100% Fish farm Wastewater , 50% FF 50% Commercial Media, and 100% CM. We use several equipment like TTS, Oven, centrifuge machine, CHNS Elemental Analyzer, colorimeter and moisturizer. Examples apparatus that we used are bottle bioreactor, shrimp, centrifuge tube, conical flask, pipet, measuring cylinder, and beaker. We combined our 4 main components in different cultured and our different discussed ratios. We put the cultured components in bottle bioreactor and under lighting for 24 hours with pump conditioning that working 24 hours. I make assumption that the best cultivation method is under 50 % Fish Farm Wastewater 50% Commercial Media.
