PENGENDALIAN JAMUR PENYEBAB BUSUK BENIH TUSAM (Pinus merkusii Jungh et de Vriese) DENGAN ASAP CAIR KAYU LABAN (Vitex pubescens Vahl)
Abstract: This study aims to
determine the effectiveness of liquid smoke from Laban wood for controlling
fungi that cause damping off on pine seeds and to determine the optimal
concentration and temperature of pyrolysis of liquid smoke from Laban wood. The
experiment was conducted at the Laboratory of Wood Technology, Faculty of
Forestry, University of Tanjungpura Pontianak. Mucor sp is the species of fungi
which used to in vitro test to determine the inhibition value. Research using
RAL Factorial methods with two treatment factors, first treatment factor is the
concentration of liquid smoke from Laban wood with 5 levels i.e. 0%, 2.5%, 5%,
7.5%, and 10%. The second treatment
factor is the temperature of the
pyrolysis liquid smoke of Laban wood with 3 levels i.e. 350ºC, 400ºC and 450ºC. Five replicates are conducted for all
treatments. Tests carried out using a PDA medium mixed with liquid smoke from
Laban wood with each concentration. Results of research showed that the concentration of liquid smoke
from Laban wood is very significant effect on the inhibition of the growth of
the fungus Mucor sp. Meanwhile the pyrolysis temperature and the interaction of
liquid smoke from Laban wood had no significant effect. Liquid smoke from Laban
wood at a concentration of 10% with a pyrolysis temperature of 400°C is the
best treatment because it can inhibited the growth of fungal Mucor sp. with the
highest value (96.33%). This antifungal activity rate fulfills the very strong
category inhibition. Liquid smoke from Laban wood can be used as biopesticide
to overcome damping off fungi on Pine seed.
