Judul: Drywood Termite Preference of Seven Species of Community Wood on Various Moisture Content Values
Abstrak: Kayu rakyat umumnya termasuk dalam Kelas Awet IV-V. Salah satu organisme perusak kayu adalah rayap kayu kering. Kondisi lingkungan seperti kadar air (KA) memengaruhi preferensi rayap kayu kering, namun belum diketahui KA ideal bagi kehidupan rayap kayu kering. Penelitian ini bertujuan untuk menganalisis preferensi rayap kayu kering terhadap tujuh jenis kayu rakyat yaitu kayu manii, akasia, jabon, karet, mahoni, pinus, dan sengon pada berbagai nilai kadar air yaitu KA segar ( >70%), KA 40-45%, KA kering udara (11-14%), dan KA kering tanur (0%) serta mengetahui mortalitas rayap kayu kering. Metode pengujian mengacu pada SNI 01 7207:2014. Hasil penelitian menunjukkan bahwa kayu jabon lebih disukai oleh rayap kayu kering dibandingkan jenis kayu lainnya pada berbagai KA yang diuji. Selain itu, rayap kayu kering cenderung lebih menyukai kayu pada KA kering udara dan KA kering tanur. Sementara itu, mortalitas rayap kayu kering pada KA segar, KA 40-45%, KA kering udara, dan KA kering tanur berturut-turut berkisar antara 78-100%, 30-100%, 24-100%, dan 16-100%., Wood from community forests generally classified into Durable Class IV-V. One of the woods destroying organisms is dry wood termites. Environmental conditions such as moisture content (MC) affect the preference of drywood termites, but the ideal MC is not yet known which is suitable for the life of the drywood termites. This study aims to analyze the preferences of drywood termites to seven species of community wood, namely manii, acacia, jabon, rubberwood, mahogany, pine, and sengon at various moisture content values, namely green MC (>70%), 40-45% MC, air dry MC (11-14%), and kiln dry MC (0%) and to know the dry wood termite mortality. The method of testing based on SNI 01 7207:2014. The results showed that jabon wood was preferred by drywood termites compared to other species of wood in various tested MC. In addition, drywood termites tend to prefer wood on air dry MC and kiln dry MC. Meanwhile, the mortality of drywood termites in green MC, 40-45% MC, air dry MC, and kiln dry MC is 78-100%, 30-100%, 24-100%, and 16-100% respectively.

Judul: Keawetan Alami Beberapa Jenis Kayu Indonesia Kurang Dikenal dari Kampus IPB Dramaga terhadap Serangan Rayap
Abstrak: 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.
