Abstract

English

The decreasing availability of timber from natural forests has led to the use of rapidly growing types of wood as alternative materials in order to satisfy the needs of the wood-based industry. In West Nusa Tenggara Province one such fast-growing species is rajumas wood (Duabanga moluccana Blume). Nevertheless, this species has poor natural durability and is therefore vulnerable to attack by wood-decaying fungi and subterranean termites. The present study was carried out with the aim of assessing the effectiveness of wood preservation treatments involving a fungicide, an insecticide and a combined fungicide-insecticide in enhancing the durability of rajumas wood. The wood preservation was performed by means of the cold-soaking method and was then followed by laboratory tests using the wood-decaying fungus Schizophyllum commune and field exposure tests. The data were analyzed using analysis of variance (ANOVA), followed by Duncan's Multiple Range Test (DMRT) at a 95% confidence level. The laboratory results showed that the fungicide treatment provided the highest resistance to fungal attack and was not significantly different from the combined of fungicide-insecticide treatment. In the field test, the combined fungicide-insecticide treatment provided the best protection against subterranean termite attack, although its performance was not significantly different from that of the insecticide treatment. Overall, the combined fungicide-insecticide treatment demonstrated greater potential as an effective wood preservation method because it simultaneously protected the wood against both major groups of wood-destroying organisms, thereby extending the service life of rajumas wood.

Menurunnya pasokan kayu dari hutan alam mendorong pemanfaatan jenis kayu cepat tumbuh sebagai bahan baku alternatif untuk memenuhi kebutuhan industri hasil hutan. Salah satu jenis kayu cepat tumbuh yang potensial di Provinsi Nusa Tenggara Barat adalah kayu rajumas (Duabanga moluccana Blume). Kayu ini memiliki kelas keawetan alami rendah sehingga rentan terhadap serangan jamur pelapuk dan rayap tanah. Penelitian ini bertujuan untuk mengevaluasi efektivitas pengawetan kayu rajumas menggunakan fungicide, insecticide, dan kombinasi fungicide-insecticide terhadap ketahanan kayu. Pengawetan dilakukan dengan metode perendaman dingin, kemudian ketahanan kayu diuji di laboratorium terhadap jamur pelapuk Schizophyllum commune serta uji lapangan. Data dianalisis menggunakan ANOVA dan uji DMRT pada taraf kepercayaan 95%. Hasil penelitian menunjukkan bahwa pada uji laboratorium, perlakuan fungicide memberikan ketahanan terbaik terhadap serangan jamur pelapuk dan tidak berbeda nyata dengan perlakuan kombinasi fungicide-insecticide. Pada pengujian lapangan, kombinasi fungicide-insecticide memberikan perlindungan terbaik terhadap serangan rayap tanah, meskipun tidak berbeda nyata dengan perlakuan insecticide. Secara keseluruhan, penggunaan kombinasi fungicide-insecticide berpotensi menjadi metode pengawetan yang lebih efektif karena mampu memberikan perlindungan terhadap dua kelompok organisme perusak kayu sekaligus sehingga dapat meningkatkan umur pakai kayu rajumas.
