Abstract

English

Rajumas wood is a type of fast-growing wood that is included in durable class IV-V. The availability of local wood is abundant and is commonly used in West Nusa Tenggara (NTB) Province. This wood has a low durability class, so it needs special treatment, namely pickling. This research aims to determine the level of absorption, retention, and penetration of rajumas wood. The samples used were the core and sapwood of Rajumas wood. This research uses a cold soaking method with 1% biocide preservative with a soaking time of 12 hours, 24 hours, and 36 hours. The results showed that the TC sample (core part; soaking time 36 hours) produced the highest absorption and penetration values, 0.2035 g/cm3 and 0.3575 cm, respectively. Meanwhile, the GC sample produced the highest retention value (sapwood; soaking time 36 hours), namely 0.0090 g/cm3. These results show that the durability of rajumas wood in the heart and sapwood is relatively high at the absorption level, while the retention level tends to be low.

Bahasa Indonesia

Kayu rajumas merupakan salah satu jenis kayu cepat tumbuh (fast growing wood species) yang termasuk dalam kelas awet IV-V. Ketersediaan kayu lokal ini sangat banyak dan umum digunakan di Provinsi Nusa Tenggara Barat (NTB). Kayu ini memiliki kelas awet rendah sehingga perlu dilakukan perlakuan khusus yaitu pengawetan. Penelitian ini bertujuan untuk mengetahui tingkat absorbsi, retensi, dan penetrasi dari kayu rajumas. Sampel yang digunakan berupa bagian teras dan gubal kayu rajumas. Penelitian ini menggunakan metode perendaman dingin dengan bahan pengawet biocide 1 % dengan lama waktu perendaman 12 jam, 24 jam, dan 36 jam. Hasil penelitian menunjukan bahwa sampel TC (bagian teras; lama perendaman 36 jam) menghasilkan nilai absorbsi dan penetrasi tertinggi, masing-masing yaitu 0,2035 g/cm3 dan 0,3575 cm. Sedangkan nilai retensi tertinggi dihasilkan oleh sampel GC (bagian gubal; lama perendaman 36 jam) yaitu 0,0090 g/cm3. Hasil ini menunjukan bahwa sifat keterawetan kayu rajumas pada bagian teras dan gubal relatif tinggi pada tingkat absorbsi, sedangkan pada tingkat retensi cenderung rendah.
