KOMPOSISI DAN STRUKTUR TEGAKAN PENGHASIL KAYU BAHAN BANGUNAN DI HUTAN LINDUNG TANJUNG TIGA, MUARA ENIM, SUMATERA SELATAN (Composition and Structure of Tree that Produce Building Materials in The Tanjung Tiga Protected Forest, Muara Enim, South Sumatra)

Abstract

ABSTRAK

Hutan Lindung Tanjung Tiga adalah hutan hujan tropis yang tersisa di Muara Enim berada pada ketinggian di atas 1300 m dpl. Keberadaan hutan ini sangat penting baik sebagai pengatur hidrologis maupun sebagai penghasil kayu. Pada umumnya bangunan rumah masyarakat di desa Tanjung Tiga masih menggunakan beragam kayu hutan, sementara keberadaan pohon penghasil kayu-kayu utama untuk bangunan ini sudah mulai berkurang. Penelitian mengenai kondisi hutan, khususnya komposisi dan struktur tegakan penghasil kayu bahan bangunan telah dilakukan pada bulan April 2013. Penelitian ini bertujuan untuk mendapatkan informasi tentang famili pohon-pohon penghasil kayu bangunan di Hutan Tanjung Tiga sebagai bahan acuan tindakan konservasi hutan baik bagi masyarakat maupun pemerintah setempat. Penelitian dilakukan dengan metode transek dan petak contoh kuadrat di tiga areal berbeda. Hasil penelitian menunjukkan adanya tiga famili penting yaitu Myrtaceae, Fagaceae dan Lauraceae, namun baik jumlah maupun diameter batangnya sangat rendah sehingga perlu segera upaya pencegahan penebangan lebih lanjut dan tindakan konservasi yang menguntungkan semua pihak. 

ABSTRACT

Tanjung Tiga protected forest is a remnant of tropical rain forests, which are located at an altitude above 1300 m asl. The existence of this forest is very important both as a regulator of hydrological, as well as the timber resources. In general, rural residential buildings in the village still use a variety of forest timber. While the presence of trees producing the main timber for the building has begun to diminish in nature. Research on the condition of forests, in particular the composition and structure of the building material stands have been carried out in April 2013. This study aimed to obtain information on trees family that produce building material in forests as a reference for forest conservation efforts both for society and local authorities. The research was conducted with nested sampling plots in three different blocks. The results showed the presence of three important families are Myrtaceae, Fagaceae and Lauraceae, but both the number and diameter of the stem so low that it needs immediate effort to prevent further logging and conservation measures that benefit all parties.
