Abstract

The objective of this research was to evaluate the natural durability of Nine Indonesian lesser known species against subterranean termite (Coptotermes curvignathus Holmgren) and dry wood termite (Cryptotermes cynocephalus Light) attacked grown in Dramaga campus Bogor Agricultural University. Sap and hearth woods from nine wood species namely mangium (Acacia mangium Wild), durian (Durio zibethinus), nangka (Arthocarpus heterophyllus), angsana (Pterocarpus indicus), afrika (Maesopsis eminii Engl), rukam (Flacourtia rukam Zoll), trembesi (Samanea saman (Jacquin) Merrill), bisbul (Diospyros discolor Willd), and ki sampang (Evodia latifolia Dc) were used in this experiment. Evaluation of natural durability of wood against termite attacked referred to SNI 01.7207-2006. The results indicated that the weight loss of wood after baited to C.curvignathus and C.cynocephalus were varied among species and positioning wood (sap and hearth woods). It was observed that hearth wood part of nangka wood was the most durable wood against C.curvignathus attacked and it was classified into 2nd class. bisbul, rukam and trembesi woods both sap and hearth wood part and heart wood of angsana wood were classified into 3rd class. mangium and afrika woods both sap and hearth wood parts were classified into 4th class. Ki sampang and durian woods both sap and hearth wood parts and sap wood part of nangka and angsana woods were classified into 5th class. Sap wood part of rukam wood was the most durable wood against C.cynocephalus attacked and it was classified into 2nd class. Bisbul, mangium, ki sampang, afrika, nangka, durian, angsana and trembesi woods both sap and hearth wood parts and heart wood part of rukam wood were classified into 3rd class.
