ABSTRAK

Hutan rakyat berpotensi menjadi solusi defisit kebutuhan kayu secara lokal maupun nasional. Optimalisasi peran hutan rakyat memerlukan perencanaan yang tepat dan data yang akurat. Penelitian ini bertujuan untuk menentukan potensi dan komposisi kayu penyusun hutan rakyat di Malimada, Kecamatan Wewewa Utara Kabupaten Sumba Barat Daya, Nusa Tenggara Timur. Penelitian menggunakan pendekatan diskriptif kuantitatif dengan metode sampling kuadrat. Sampel berjumlah 10 plot yang diambil secara puposive. Indeks Nilai Peneting (INP) digunakan untuk menggambarkan potency kayu dan komposisi jenis penyusun hutan rakyat. Hasil penelitian menunjukkan bahwa mahoni (Swietenia macrophylla King) mendominasi tegakan dengan nilai INP pada tingkat sapihan, tiang dan pohon berturut-turut adalah 188,28; 211,28 dan 246,04. Struktur tegakan yang ada memiliki karakteristik yang hampir sama dengan hutan alam,  hal ini terlihat dari grafik distribusi tingkat pertumbuhan yang berbentuk (J) terbalik (reverse J-shape).

ABSTRACT

Private forests potentially solve the problem of local and national wood deficit. Optimizing the role of private forests, needs proper plannings and accurate data. This study aimed at determining wood potency and composition on private forest of Malimada, North Wewewa sub district, Southwest Sumba District of East Nusa Tenggara. This research used quantitative descriptive approach. Samplings purposive used quadrat methods with 10 plots were established. Important Value Index (IVI) was employed in order to depict wood potency and trees composition of private forest. The research results revealed that standing stock predominantly by mahogany (Swietenia macrophylla King.) with IVI at saplings, poles, and trees level were 188.28; 211.28 and 246.04 respectively. The existing structure stock has similar characteristics to the nature forest, this was indicated by reverse J-shape level of growth distribution curve.
