EFEKTIVITAS PENGAWETAN DENGAN TEKNIK INFUS DAN BANDAGE PADA POHON BALAM TERHADAP SERANGAN RAYAP KAYU KERING
Main Article Content
Abstract
Currently, the availability of red meranti, kulim and mersawa wood is commonly used as raw material for “jalur” construction
in Kuansing Regency, Riau Province, are increasingly scarce, while the need is getting higher. Accordingly, it is necessary to choose
alternative wood types that have similar strength and durable properties compatible with red meranti, kulim and mersawa wood to
meet specifications for the “jalur” construction. This paper studies the effectiveness of preservative treatment by infusion technique
and bandage use against dry wood termite. Balam (Macaranga conifera Muell. Agr.) was chosen as alternative wood for making
the path because currently this wood is abundant but not much used for making pathways. The results of field observations indicate
dry-wood termites attacke the path stored on land, so it is necessary to preserve the path so that they are not attacked by wood
destroying organisms, particularly the dry-wood termites. Preservation treatments on standing trees using complex boron compounds
by infusion and bandage techniques were examined to increase the durability class of balam wood. Testing of dry-wood termite
attack was carried out according to the SNI 7207-2014 method. The data were processed using a completely randomized factorial
design. The analysis results showed that the preservation by infusion and bandage techniques was significantly different in terms of
weight reduction and mortality of termites. Observation on the degree of attack visually on the control and infusion technique was
40 (hold) lower than the bandage technique 70 (moderate). The highest mortality in infusion technique was 90.67% compared to
control 86.08%, and the bandage was 61.75%. Preservation using the infusion technique showed a higher boron content compared
with the bandage technique.
