Abstract

Rubber wood (Hevea brasiliensis) is a wood with low durability wood. In general, rubber wood is preserved by chemicals which are relatively not environmental friendly. This study was conducted to evaluate the potential of liquid smoke from pyrolysis of palm oil kernel and turmeric extract as wood preservatives. Rubber wood was soaked in 5% w/v of liquid smoke and turmeric extract, respectively for 2, 8, and 14 days which preservation was carried out for six months. Formaline and boric acids was used for comparison as well. The used parameters were preservative retention, moisture content during storage, color changes, and damage level. The results indicated that the longer the immersion, the greater the preservative retention and water content. Turmeric extract and liquid smoke provided a brownish yellow and light brown color. In general, liquid smoke for two days of immersion adequate for six months preservation whereas turmeric acid for two months.

Abstract

Kebutuhan kayu terus mengalami peningkatan. Sementara itu, ketersediaan kayu hutan semakin berkurang dan terbatas. Kayu karet dapat menjadi salah satu alternatif pengganti kayu alam. Untuk meningkatkan ketahanan kayu karet dari organisme perusak kayu seperti serangga dan jamur, perlu dilakukan pencegahan dan pengawetan. Penggunaan pengawet kimia diduga mempunyai dampak negatif terhadap lingkungan. Oleh karena itu perlu alternatif pengawet organik yang lebih ramah lingkungan. Aplikasi bahan pengawet pada kayu karet alam dapat menggunakan teknik perendaman panas. Faktor perlakuan terdiri atas jenis bahan pengawet dan lama perendaman. Bahan pengawet yang digunakan berupa asap cair 5%, ekstrak kunyit 5%, formalin 5% dan boraks 5%. Sedangkan waktu perendaman kayu karet terdiri dari 0 (kontrol), 1, 3, dan 5 jam. Parameter yang diamati yaitu retensi bahan pengawet, penyusutan berat, warna dan derajat proteksi terhadap kerusakan. Hasil penelitian menunjukkan bahwa penggunaan asap cair sebagai bahan pengawet kayu karet lebih baik dibandingkan ekstrak kunyit. Retensi dan derajat proteksi asap cair sebagai bahan pengawet tidak berbeda dibandingkan dengan bahan pengawet kimia, boraks dan formalin. Penggunaan asap cair hanya akan mempengaruhi warna kayu karet menjadi cokelat muda setelah perendaman. Warna ini akan berubah selama proses penyimpanan menjadi cokelat sangat pucat. Aplikasi terbaik bahan pengawet asap cair adalah perendaman selama 1 jam. Diterima : 12 Maret 2015; Direvisi : 28 April 2015; Disetujui : 7 Mei 2015  How to Cite : Vachlepi, A., Suwardin, D., & Hanifarianty, S.
