      Abstract
      The objective of this research was to obtain information on species composition and structure of lowland tropical rain forest in Sentarum Lake National Park, West Kalimantan. The research was carried out from 26 to 31 December 2003 and from 20 January to 5 February 2004 on the foot slope of Semujan Hill in Sentarum Lake National Park. To carry out the research, 10 sample units (SU’S) with size of 10 m x 10 m each, were placed, based on systematic sampling with random start scheme, with distance of 10 m between each SU. On each SU, trees with diameter > 2 cm were identified and diameter (DBH) and height were recorded. Eighty four (84) tree species were found in a 0.1 ha SU, consisting of 32 families, dominated by 16 species of Dipterocarpaceae, followed by 9 species of Guttiferae and 5 species of Melastomataceae. Tree density decreased exponentially with increasing the diameter of trees.
       
      Tujuan dari penelitian ini adalah untuk memperoleh informasi mengenai struktur dan komposisi jenis hutan hujan tropis dataran rendah di Taman Nasional Danau Sentarum (TNDS), Kalimantan Barat. Penelitian ini dilaksanakan pada tanggal 26 sampai 31 Des 2003 dan 20 Jan sampai 5 Feb 2004 di kaki lereng Bukit Semujan di Taman Nasional Danau Sentarum. Dalam penelitian ini dibuat 10 unit contoh dengan ukuran masing-masing 10 m x 10 m yang peletakannya dilakukan mengikuti rancangan systematic sampling with random start, dengan jarak antar plot sejauh 10 m. Pada setiap unit contoh, pohon dengan diameter ≥ 2 cm diidentifikasi dan dicatat ukuran diameter (DBH) serta tingginya. Hasil peneliitan menunjukkan bahwa terdapat 84 jenis pohon ditemukan dalam 0,1 ha unit contoh, yang termasuk ke dalam 32 famili, didominasi oleh 16 jenis dari famili Dipterocarpaceae, disusul oleh 9 jenis dari famili Guttiferae dan 5 jenis dari famili Melastomataceae. Dalam hutan ini, kerapatan pohon menurun secara eksponensial seiring dengan bertambahnya ukuran diameter batang.
