WHEY TAHU SEBAGAI PENGHASIL BIOLEKTRISITAS PADA SISTEM MICROBIAL FUEL CELL DENGAN LACTOBACILLUS PLANTARUM
ABSTRACT: Bioelectricity of
soy whey in Microbial Fuel Cell system with Lactobacillus plantarum has been
performed. This study aims to determine the capacity of soy whey as a substrate
in the MFC system and determine the influence of the speed of agitation against
potential difference generated. The potential difference compared to different
substrates, namely soy whey, glucose and lactose. Determination of the
potential difference in speed variation agitation performed with variations 30,
60, 90, 125 and 250 rpm. The potential difference at the maximum voltage
variation of the substrate obtained by soy whey by 33.3 mV / 100 mL at the 15th
hour, whereas glucose and lactose reaches the maximum potential difference at
the 12th hour with a relatively similar value. Agitation speed that generates
the highest potential difference in soy whey substrate was obtained at 90 rpm
with maximum potential difference of 63.1 mV / 100mL at the 14th hour.
