AB  - In this work, suspended and immobilized Saccharomyces cerevisiae yeast in 
      alginate was utilized as a biocatalyst to interact with different concentrations 
      of tofu wastewater for microalgae microbial fuel cell (MMFC) application. 
      Operating conditions are one of the factors that impact the MMFC's performance, 
      thus they must be optimized. The response surface approach was used to optimize 
      operating conditions, which involved CCD-randomized by five levels of two 
      variables. With an average voltage of 0.13 V, power density of 13.94 mW.m(-2), 
      and current density of 102.20 mA.m(-2), bioelectricity output produced more 
      suspended yeast than immobilized yeast. The average voltage of MMFC with 
      immobilized yeast was 0.123 V, the power density was 11.25 mW.m(-2), and the 
      current density was 91.82 mA.m(-2). Immobilized yeast, on the other hand, led in 
      faster stabilization of the resulted electrical output. When compared to 
      suspension yeast, immobilized yeast removed more COD. The best conditions were 
      reached with a yeast concentration of 10.89% w/v and a wastewater concentration 
      of 56.94%, resulting in a power density and COD removal of 11.25 mW.m(-2) and 
      31.82%, respectively. The effect of yeast and wastewater concentrations on power 
      density and COD removal revealed that the model was well supported by 
      experimental results.
