Pengaruh Interaksi Mikroalga Chlorella Sp. Dan Bakteri Bioprisma Terhadap Penurunan Polutan Dan Produksi Lipid Pada Medum Limbah Cair Tahu
Tofu liquid waste can be utilized by microalgae Chlorella sp. as a source of nutrition for its growth.Utilization of nutrients by Chlorella sp. can reduce COD levels and total nitrogen of tofu liquid waste and also play an important role in lipid formation from microalgae Chlorella sp. The purposes of this research are (1) to know the interaction between a complex microorganism contained in Bioprisma as a decomposer agent with the addition of photosynthetic microalgae Chlorella sp. as an oxygen producer in reducing organic loads of tofu liquid waste. (2) is to determine the interaction between Chlorella sp. and bacteria contained in Bioprisma for microalgae growth and lipid production. The study conducted in batches with the bacteria addition treatment in 5 different levels, that is 0 (without the addition of bacteria), addition of bacteria as many as 0,25; 0,50; 0,75 and 1 (% v/v). The processing is carried out for 13 days with solar irradiation in the photobioreactor. As a result, the highest density and the highest growth rate are obtained from the treatment of 1% Bioprisma, with the result as many as 5,65 x 106 cell/ml and 0,21 /day. The treatment with the addition of 1% was able to produce lipids, the efficiency of COD and the totals nitrogen removal were 20,93%; 96,30% and 71,89% at the best-removing detention time, happened in days-13.
Keywords: Chlorella sp., Bioprisma, Tofu Liquid Waste, COD, Total Nitrogen, Lipid, Contact Time.
