چکیده
Abstrak. Kabupaten Aceh Besar merupakan wilayah yang beberapa kawasan nya berbatasan dengan pantai, diantaranya yaitu Desa Lambadeuk Kecamatan Peukan Bada. Kawasan desa tersebut sangat dekat di ini terdapat lahan dipengaruhi oleh pasang surut air laut kategorikan ke dalam rawa zona I. Penelitian bertujuan untuk mengetahui Karakterisasi dan Genesis Lahan Tambak Bada Besar. Metode digunakan penelitian adalah survai deskriptif kuantitatif parameter karakteristik morfologi diamati lapangan yaitu: batas kedalaman horison tanah, topografi warna matriks karatan struktur kosistensi plastisitas perakaran. Parameter fisika dianalisis laboratorium tekstur bobot isi, sedangkan kimia pH, C-organik, basa-basa dd (Ca, Mg, Na, K), asam-asam (Al H), kapasitas tukar kation, kejenuhan basa. Hasil menunjukkan bahwa karakterisasi tambak (a) morfologi: memiliki E Bw ketebalan 28 cm tanah pada zaitun abu-abu hijau tua kelabu; (b) fisika: kelas pasir berlempung Bw; serta kriteria isi sedang; (c) kimia: pH agak alkalis Bw, C-organik rendah, KTK (kapasitas kation) KB (kejenuhan basa) tinggi Bw. Faktor-faktor pembentuk bahan induk berasal dari batuan sedimen/aluvium (kerikil, pasir, lumpur), tipe iklim C (agak basah), relief datar, umur holosen (0,6 juta tahun lalu – sekarang), ordo Inceptisol. Adapun proses genesis terjadi eluviasi gleisasi.Abstract. Regency is an area where several areas are bordered by the coast, including Village, District. The village very close to beach, in this there a swamp that influenced tides of sea water which categorized into zone This study aims determine Characteristics and on Pond Village Sub-district Regency. method used quantitative descriptive survey with parameters morphological characteristics observed field, namely: boundaries depth soil horizons, topographic soils, matrix color rust, structure, consistency, plasticity, roots. physical characteristic analyzed laboratory are: texture bulk density, while chemical C-organic, bases acids cation exchange capacity, base saturation. results showed tidal swamps pond land characteristics: has horizons thickness horizon olive gray dark green ; class sandy loam sand at as well having criteria for moderate density; slightly alkaline horizon, low organic C, CEC (cation capacity), high (base saturation) horizon. Soil-forming factors ponds parent material derived from sedimentary/aluvium rock (gravel, sand, mud), climate type (slightly wet), flat relief, Holocene age (0.6 million years ago now), order processes occur eluviation gleization.
