Abstract

Sandalwood population in Timor Island has been on a decrease at an alarming rate. The decrease reached 85% in 10 years, from 1987-1988 and 1997-1998. The present status of sandalwood on the Timor Island has been included as a vulnerable specie. Sandalwood cultivation and recovery efforts is systematic, this involves a planned process. To achieve any significant success, it must be supported by data and information about the location suitable for the growth of sandalwood. This study aims to provide data and information on the land suitability for sandalwood (Santalum album Linn.) in Timor Island. The study was conducted by analysis of soil chemistry and physics and biophysical conditions overlay with FAO procedure (1976). The analysis showed an actual suitalbility area for development of sandalwood in each district are as follows: Belu of 125,216.69 ha (51.32%), Timor Tengah Utara of 163,554.16 ha (61.26%), Timor Tengah Selatan of 278,818.77 ha (70.64%), Kupang of 263,677.77 ha (44.73%), Kupang City of 8994.48 ha (49.89%) of the total land area of each district.

Abstract

This study aimed to determine mangrove forest structure and composition in Golo Sepang Village, Manggarai Barat District. Important value index and diversity index value obtained from mangrove vegetation analysis were used as indicators for determining mangrove forest structure and diversity. Transect method with square frame along the line was applied in vegetation analysis. Totally 10 lines and 30 plots were applied for getting types of mangrove, growth parametersvalue (height and diameter) and others related information. This study found that the stucture of mangrove consist of 5 familyes with 10 species, namely: Rhizophoraceae (Ceriops tagal (Perr), Rhizophora apiculata (Bi), R. mucronata Lmk., Bruguiera parviflora (Roxb.), B. sexangula (Lour) dan B. gymnorrizha (L.) Lamk.), Fabaceae (Derris trifoliata Lour), Meliaceae (Xylocarpus granatum Koen), Pteridaceae (Acrosthicum aereum Linn) and Lythraceae (Phempis acidula Forst). R. apiculata (Bi) is the most dominant species founded in 7 of 10 total sites. Two sites, Sotri and Muara Kiri, have the highest important value index (300%) for R. Apiculata species. The highest individual density is found at Sotri site, with value 1.300 tree/hectare, while the lowest density, 100 trees/hectare is found at Muara Kanan site. In diversity of mangrove, all sites were categorized as low with highest diversity index value 1,06.Keywords: Mangrove forest, structure and composition, Golo Sepang

Abstract

Perubahan kawasan mangrove menjadi tambak banyak terjadi di Kabupaten Kupang. Silvofishery merupakan model pengusahaan tambak yang terpadu dengan konservasi sehingga nilai ekonomi dan ekologinya dapat dicapai secara bersamaan. Tujuan penelitian untuk memperoleh informasi tentang besarnya pengaruh  silvofishery terhadap produktivitas tambak dan kualitas lingkungan. Penelitian ini menggunakan metode deskriptif kuantitatif dengan parameter kualitas air, pertumbuhan tanaman, dan pertumbuhan bandeng. Plot yang digunakan dalam penelitian ini meliputi plot silvofishery dan plot untuk pengukuran kualitas air. Plot silvofihery terdiri atas plot A, B, C, dan D dengan variasi jarak tanam. Plot pengukuran kualitas air meliputi: tambak dengan mangrove, tambak tanpa mangrove, dan tambak dengan mangrove yang sudah tidak dibudidayakan ikan. Hasil penelitian menunjukkan bahwa parameter kualitas air di dalam tiga plot tambak adalah: (1) salinitas yang rendah berkisar antara 7-7,7%; (2) pH netral sampai agak basa atau 7,8-8,8; (3) Chemical Oxigen Demand (COD) antara 98,2-172,9 mg/l atau dikategorikan sebagai air tercemar;  dan (4) Biological Oxygen Demand (BOD) antara 5,6-5,8 mg/l atau masih dalam batas ambang. Kegiatan silvofishery di Bipolo layak untuk dikembangkan dan menguntungkan secara finansial, dilihat dari nilai BCR >1. Rata-rata pertumbuhan tanaman dan penambahan berat ikan pada plot C lebih tinggi dibandingkan dengan plot A dan B.
