PENGIKATAN KARBON DIOKSIDA DENGAN MIKROALGA (CHLORELLA VULGARIS, CHLAMYDOMONAS SP., SPIRULLINA SP.) DALAM UPAYA UNTUK MENINGKATKAN KEMURNIAN BIOGAS
ABSTRACT: Biogas is gas which
the main contents are 55-75% methane and 25-45% carbon dioxide. Removing CO2
content in biogas will improving biogas’s quality itself, so that the calorific
value on biogas will be higher. One way
to removing CO2is with utilize microalgae’s ability to absorb CO2in
photosynthesis phenomena. Purposes of this research are to measure the optimal
amount of CO2 absorbed by microalgae and determine the type of microalgae is the
best at absorbing CO2. This research designed with variety types of microalgae
such as Chlorella vulgaris, Chlamydomonas sp., and Spirulina sp. and variety
gas flow rate variabels are 20, 60, 100, 150, 200, 300 mL / min. From analysis
results, at gas flow rate 20 mL / min
each microalgae can absorb CO2optimally. Spirullina sp. has the highest
percentage of absorbed CO2 among Chlorella vulgaris and Chlamydomonas sp.,
which is by 8,91%. This study also
showed that Spirullina sp. has 0,136 g/L biomass enhancement, and that
is the highest biomass enhancement among Chlorella sp. and Chlamydomonas sp.,
which only has 0,136 g/L and 0,130 g/L biomass enhancement.
