Abstract

Kayu jelutung (<i>Dyera costulata</i>) merupakan salah satu jenis tanaman endemik di Kalimantan yang mulai langka. Tujuan penelitian ini adalah untuk menganalisis karakteristik pertumbuhan kayu jelutung yang dibudidayakan oleh masyarakat di Kalimantan Tengah di lahan gambut. Pengolahan lahan dengan tanpa bakar menjadikan hutan tanaman rakyat (HTR) ini ramah lingkungan. Sebanyak 38 pohon jelutung dari 1 blok HTR diukur diameter dan tinggi pohonnya, selanjutnya dikelompokkan dalam kategori pertumbuhan cepat, sedang, dan lambat. Dari masing-masing kelompok diambil 1 pohon yang memenuhi persyaratan. Sampel setebal 2 cm diambil dari ketinggian 1,3 m dari permukaan tanah dan setiap 2 meter ke arah ujung pohon untuk pengukuran kadar air (KA), berat jenis (BJ), anatomi kayu, nilai turunan serat, dan kandungan kimia kayu. Hasil pengujian menunjukkan bahwa kayu jelutung memiliki BJ rendah dan serat pendek sehingga termasuk kelas 2 untuk pembuatan pulp dan kertas. Kandungan kimia kayu jelutung menunjukkan kandungan ektraktif larut alkohol benzena yang cukup rendah dan bisa digunakan sebagai bahan baku pulp dan kertas. Selain itu, kayu jelutung juga sesuai untuk digunakan sebagai bahan kayu lapis. Characteristics of Jelutong Wood ((<i>Dyera costulata</i>) from Community Forest in Central KalimantanAbstractJelutong wood (<i>Dyera costulata</i>) is one of the endemic tree species in Kalimantan which is starting to become scarce. This research aims to analyze the growth characteristics of jelutong wood planted by the community in peatland in Central Kalimantan. Land processing without burning makes this community plantation forest environmentally friendly. Thirty-eight trees of jelutong from one block were measured diameter and three height, end then categorized to fast, medium, and slow-growing. One tree from each category was harvested. Two centimeters of the disk were collected from each harvested trees from a 1.3 meter height and continued every 2 meters to the peak of trees to measure water content, specific gravity, anatomical properties, derived wood, and chemical content of jelutong wood. From the analyses, jelutong has low specific gravity and short fibers, categorized into class two for pulp and paper raw materials. Extractive content in alcohol benzene from jelutong wood was low that preferable for pulp and paper. On the other hand, jelutong wood is suitable for plywood raw materials.
