Utilization of Wood Waste Mahang (Macaranga sp.) From Sawmill Industry For Making Wood Vinegar
ABSTRACT: Wood vinegar is the
result of condensation and combustion products directly or indirectly. One of
the methodes to make wood vinegar is by condensing the smoke products of incomplete
combustion (pyrolysis). Materials used for the manufacture of wood vinegar is
mahang wood waste from the sawmill industry in the form of sawdust, shavings
and slashes. This study aims to determine how much rendement, chemical
constituents of wood vinegar (phenol, total acid and pH) as well as
the colors of the various forms of raw materials. This experiment was carried
out using a completely randomited design (CRD) consist of 3 treatments and 5
replications with parameters analyzed were rendement, chemical content and
color wood vinegar produced. These results indicate that the form of raw
materials affect rendement, chemical content, and color. Sawdust (C1) rendement
yield of 14.66 %, phenol content of 15,48 mg/l, total acid of 5,08 %, pH of 2,1
and color of wood vinegar is yellow light brown. Chips (C2) rendement yield of
20,67 %, phenol content of 18,61 mg/l, total acid of 5,78 %, pH of 2,0 and
color of wood vinegar is yellow brown. Slashes (C3) rendement yield of 38,98 %,
phenol content of 18,80 mg/l, amount 7,72 % total acid, pH of 1,9 and color of
wood vinegar is yellow dark brown. Recommended for more efficient utilization
of wood waste mahang (Macaranga sp.). As materials are shaped blade of wood
vinegar, because it has the highest rendement and good quality wood vinegar.
