Attempt procedure in this research cover the, bentonit drainage, analyse the raw material, attempt execution with the variation of condition operate for the (variable change) covering temperature (60 oC ; 70 oC ; 80 oC ; 90 oC ; 100 oC), time reacted (20 minute; 25 minute 30 minute; 35 minute; 40 minute), bentonit consentrate (5%; 10%; 12,5%; 20%; 25%). Process here in after analyse the result of from optimasi conducted at temperature consdition (60 oC - 100 oC), time reacted (20 minute; 25 minute; 30 minute; 35 minute; 40 minute), bentonite concentrate (5%; 10%; 12,5%; 20%; 25%) got by a cooking oil clearness best secondhand at temperature 100 0C, time reacted 20 minute, and bentonite concentrate 25 %.
