Abstrak

Bambu termasuk dalam famili Gramineae atau suku rumput-rumputan. Tanaman bambu tersebar di seluruh kawasan nusantara. Bambu berpotensi untuk mensubstitusi kayu. Penelitian ini bertujuan untuk mengetahui jenis-jenis, jumlah rumpun, kerapatan, dan penyebaran tiap jenis bambu di Blok Pendidikan dan Penelitian dalam kawasan Tahura Wan Abdul Rachman. Penelitian ini dilakukan dengan metode inventarisasi menggunakan petak ganda dengan jumlah petak contoh sebanyak 40 buah. Identifikasi bambu dilakukan dengan analisis morfologis. Analisis data dilakukan untuk mengetahui kerapatan dan frekuensi tiap jenis bambu. Hasil penelitian menunjukkan bahwa di Blok Pendidikan dan Penelitian dalam Kawasan Taman Hutan Raya Wan Abdul Rachman diperoleh 6 jenis bambu. Jenis bambu yang ditemukan yaitu bambu tali, bambu gombong, bambu hitam, bambu kuning, bambu ater batu, dan bambu betung. Bambu gombong memiliki jumlah rumpun terbanyak, yaitu rata-rata 18,125 rumpun/hektar, dengan jumlah individu rata-rata sebanyak 1.139,34 batang/hektar. Sedangkan jika dilihat jumlah individu per rumpun, maka bambu hitam memiliki jumlah paling banyak dibandingkan jenis bambu lainnya, yaitu Debri Rezki Oktiphan Bayu Hakiki sebanyak 156 batang/rumpun. Berdasarkan data frekuensi, dapat dikemukakan bahwa bambu gombong memiliki penyebaran paling luas dengan nilai frekuensi sebesar 0,725. Adapun bambu kuning, bambu ater batu, dan bambu betung menyebar secara terbatas dengan nilai frekuensi sebesar 0,025. Disarankan melakukan upaya pelestarian jenis bambu yang populasi dan penyebarannya terbatas misalnya bambu betung melalui kegiatan penanaman didalam kawasan. Kata kunci: bambu, identifikasi, taman hutan raya wan abdul rachman ABSTRACT Bamboo is classified in to Gramineae family. Bamboo is widely spread in all over of Indonesia archipelago. Bamboo has a potential to substitute wood. The research was aimed to identify the variety, the number of cluster, density, and spreading of each bamboo species in Block of Research and Education, Great Forest Park of Wan Abdul Rachman. Forest inventory with double plot was employed as the research method. Fourty plots was made as sample plots. Morphological analysis was used as bamboo identification method. Data analysis was employed to find out density and frequency of each bamboo species. The results of the research showed that there were six species of bamboo in the Block of Research and Education, Great Forest Park of Wan Abdul Rachman. The species of bamboo found were Gigantochloa apus (bambu tali), Gigantochloa verticillata (bambu gombong), Gigantochloa atroviolaceae (bambu hitam), Bambusa vulgaris (bambu kuning), Gigantochloa atter (bambu ater batu), and Dendrocalamus asper (bambu betung). Bambu gombong had the most cluster number, that was in average 18.125 clusters/hectare and the number of stem was in average 1,139.34 Debri Rezki Oktiphan Bayu Hakiki stems/hectare. Based on the number of stem per cluster, bambu hitam had the most number of stem within each cluster (in average 156 stems/cluster). Bambu gombong had the widest spreading with the frequency of 0.725. whereas other species more limited spreading with the frequency of 0.025. It is suggested to preserve the bamboo species that has low population and spreading level such as bambu betung, through planting project (reboisation).
