Abstract

Degradasi hutan di Indonesia, yang menyebabkan penyusutan luas tutupan hutan, memotivasi pelaksanaan Kegiatan Rehabilitasi Hutan dan Lahan (RHL). Kegiatan RHL bermaksud untuk memulihkan hutan dan lahan agar dapat berfungsi secara normal dan lestari sebagai sistem penyangga kehidupan. Pentingnya data yang mendukung dan strategi pemilihan jenis tanaman yang tepat menjadi kunci dalam meningkatkan efektivitas pelaksanaan RHL. Penelitian ini bertujuan untuk mengetahui komposisi dan struktur tegakan di kawasan hutan RPH Temutung, KPH Ropang. Metode yang digunakan dalam penelitian ini adalah metode deskriptif kuantitatif. Luas areal lokasi penelitian ini adalah 281,4 ha dengan intensitas sampling 1% sehingga diperoleh 70 plot pengamatan. Pengambilan data dilakukan menggunakan plot berukuran 20 x 20 m dan 200 x 150 m. Data yang dikumpulkan meliputi jenis vegetasi, jumlah pohon, tingkat pertumbuhan, diameter pohon, tinggi pohon, dan luas tajuk pohon. Hasil dari penelitian ini ditemukan sebanyak 41 jenis, 39 marga, dan 20 suku. Jenis dengan INP tertinggi pada tingkat pohon yaitu Tectona grandis (43,07%), pada tingkat tiang yaitu Tectona grandis (55,07%), pada tingkat pancang yaitu Psidium guajava (66,52%), dan  tingkat semai yaitu Eupatorium odoratum (57,31%). Indeks Keanekaragaman kawasan hutan RPH Temutung termasuk dalam kategori sedang.  Indeks Kemerataan vegetasi tingkat pertumbuhan semai dan pancang rentan terhadap gangguan. Indeks Kekayaan jenis rendah menuju sedang. Indeks Dominansi menunjukkan terdapat jenis yang dominan pada setiap tingkat pertumbuhan. Struktur tegakan hutan RPH Temutung secara horizontal dan vertikal dinyatakan normal dan masih memiliki regenerasi yang baik, sedangkan pola persebaran profil tegakan vegetasi yang berada di kawasan hutan produksi terbatas RPH Temutung tersebar secara acak, sedangkan pada kawasan hutan lindung tersebar secara bergerombol.

Abstract

The sustainable management of forest resources has become increasingly important, particularly in community-managed forests where non-timber forest products (NTFPs) play a crucial role in local livelihoods and biodiversity conservation. This study aims to identify the types of NTFPs, the density and diversity of vegetation, and the average growth of NTFPs in the Community Forest (HKm) of Aik Bual. The research utilized a descriptive method and was conducted from August to September 2022 on HKm land in Aik Bual Village, Central Lombok, which received enrichment assistance for NTFP plants. The study population consisted of 164 HKm farmers, with an average land ownership of 50-60 ares. The sample used in this study comprised 20 plots managed by farmers. On these plots, a main plot of 25 m x 40 m and subplots of 20 m x 20 m and 10 m x 10 m were established. In the 25 m x 40 m plots, all NTFPs were surveyed, while other vegetation at tree and pole levels was measured in the 20 m x 20 m and 10 m x 10 m subplots. Parameters measured included diameter, height, and vegetation type. The analysis included vegetation diversity, density, dominance index, and NTFP growth. The results showed that there are nine types of NTFPs in the Community Forest of Aik Bual, namely avocado, durian, guava, mango, jackfruit, cocoa, silk cotton tree, melinjo tree, and sapodilla. Additionally, five types of non-wood forest products were identified. The vegetation density at the tree level in HKm Aik Bual was 515 individuals/ha, while at the pole level it was 545 individuals/ha. The highest importance value index (IVI) at the tree level was recorded for rajumas and mahogany, with values of 82% and 78,70%, respectively. At the pole level, durian and avocado had the highest IVI, with values of 123,69% and 70,08%, respectively. The dominance index at the tree level was dominated by rajumas and mahogany with a value of 0,07, while at the pole level, durian dominated with a value of 0,17. The average diameter growth for avocado at ages 1, 4, 5, 10, and 20 years was 1,49 cm/year, 2,42 cm/year, 2,55 cm/year, 1,98 cm/year, and 1,64 cm/year, respectively. For durian, the average diameter growth at these ages was 1,43 cm/year, 2,76 cm/year, 2,35 cm/year, 1,68 cm/year, and 1,71 cm/year. The average height growth for avocado at ages 1, 4, 5, 10, and 20 years was 1,33 m/year, 1,42 m/year, 1,62 m/year, 1 m/year, and 0,60 m/year, respectively. For durian, the average height growth at these ages was 1,24 m/year, 1,39 m/year, 1,50 m/year, 1,07 m/year, and 0,71 m/year. Keywords: NTFS, Growth, Dominance Index, Vegetation Density
