Abstract

Ficus spp. merupakan salah satu tumbuhan dari suku Moraceae yang sering dikenal dengan beringin-beringinan atau pohon ara. Jenis tumbuhan Ficus melimpah di hutan dataran rendah dan memegang peranan penting dalam ekologi. Kawasan hutan Tangkahan merupakan salah satu kawasan hutan konservasi yang terletak di Sumatera Utara dan lokasi ditemukan jenis Ficus spp. Hal ini bertujuan untuk menganalisis faktor ekologi tumbuhan Ficus spp. dan memperoleh informasi mengenai pemanfaatannya di kawasan hutan Tangkahan, yang dilaksanakan pada bulan Maret hingga Juni 2020. Pengambilan sampel dilakukan dengan menggunakan metode purposive sampling yaitu memilih lokasi secara sengaja. Data vegetasi di analisis dengan nilai kerapatan (K), Indeks Keanekaragaman (H’), Indeks Keseragaman (E) dan Indeks Similaritas (IS). Karbon tersimpan dianalisis dengan persamaan allometrik Kettring’s dan unsur hara tanah dianalisis di laboratorium. Diperoleh 12 jenis Ficus dengan 576 individu/ha. Kerapatan jenis Ficus spp. pada seluruh tingkat pertumbuhan berkisar antara 1–11 individu/ha. Indeks keanekaragaman seluruh tingkat pertumbuhan tergolong sedang dan Indeks keseragaman seluruh tingkat pertumbuhan tergolong tinggi. Indeks Similaritas berkisar antara 16.67–75%. Karbon tersimpan pada lokasi ini sebesar 8.74 ton C/ha. Analasis unsur tanah dilakukan pada katagori C-organik, N-total, P-Bray I, K-dd, Ca, Mg dan pH.

Abstract

Water is a basic necessity for living things. The catchment area (DTA) is very important to be conserved to maintain water availability and prevent the exploitation of springs. Studies on water and land conservation in Beji Village, Ngawen Sub-district are still very limited, especially DTA outside Wonosadi indigenous forest area. This study aims to study structure and composition of tree vegetation in DTA Wonosadi, Gunungkidul. Determination of DTA analyzed by using ArcGIS 10.2 with overlay of Hydrogeology Map, Indonesian Earth Map (RBI), and QuickBird Image. Analysis of vegetation in the analysis using Microsoft Excel software. Tree vegetation analysis used 10 m x 10 m square plot (40 plots) on each vegetation density class of DTA. The results showed that area of DTA Wonosadi was 23.300.924 m2. S. macrophylla King has highest density overall. S. macrophylla King, Tectona grandis L and Tectona grandis L has the highest Importance Value Index (IVI) of each vegetation class. This research concluded that tree vegetation structure in DTA Wonosadi is dominated by poles growth form. Tectona grandis L. is species that has the highest INP, which potentially affect ground water availability and reduce water discharge.
