Abstract

Keanekaragaman cacing tanah pada suatu habitat dapat dipengaruhi oleh kondisi fisik kimia dan habitat tersebut. Penelitian mengenai keanekaragaman cacing tanah pada tiga tipe habitat di Kecamatan Pontianak Kota telah dilakukan pada bulan Desember 2012. Penelitian ini bertujuan untuk mengetahui keanekaragaman cacing tanah di Kecamatan Pontianak Kota dan faktor lingkungan yang mempengaruhinya. Plot sampling ditentukan secara acak sebanyak 5 plot berukuran 5x5 m2 pada setiap lokasi. Sampling menggunakan metode kuadrat berukuran 30x30 cm2 dan hand-sorting. Komposisi cacing tanah tertinggi terdapat di kebun langsat dan lahan terlantar sedangkan yang terendah di persawahan. Genus Pontoscolex memiliki kepadatan tertinggi sedangkan yang terendah dari genus Pheretima. Keragaman jenis tertinggi terdapat di lahan terlantar (H’=1,2438) karena memiliki vegetasi yang beragam dan rapat. Keragaman terendah ditemukan pada lahan persawahan (H’=0,6931), hal itu terjadi salah satunya akibat pemakaian pupuk dan bahan kimia pertanian secara intensif.
