Keanekaragaman Arthropoda pada lahan bawang merah semi organik dan anorganik Desa Torongrejo Kota Batu

INDONESIA:

Bawang merah merupakan komoditas sayuran yang cukup banyak dibudidayakan di daerah Batu. Budidaya bawang merah yang ada di Desa Torongrejo Kota Batu menggunakan konsep pertanian semi organik dan anorganik. Penggunaan pestisida yang tinggi menyebabkan turunya keanekaragaman arthropoda. Keanekaragaman arthropoda dapat digunakan sebagai indikator kestabilan ekosistem, sehingga penelitian ini bertujuan untuk mengidentifikasi Arthropoda, mengetahui keanekaragam pada pertanian bawang merah semi organik dan anorganik Desa Torongrejo Kota Batu.

Penelitian ini dilakukan di Desa Torongrejo Kota Batu dan identifikasi arthropoda dilakukan di laboratorium Ekologi Jurusan Biologi Universitas Islam Negeri Maulana Malik Ibrahim Malang, pada bulan Juni sampai Agustus 2012. Penelitian dilakukan pada lahan pertanian bawang merah seluas 600 m2 dengan menggunakan metode mutlak (Pengamatan Langsung) dan metode relatif (Pit Fall Trap).

Hasil penelitian pada lahan bawang merah semi organik 10 ordo 18 famili dan 1136 individu meliputi herbivora ( 8 famili), dan predator (10 famili, sedangkan lahan anorganik terdiri dari 9 ordo, 17 famili dan 1153 individu meliputi herbivora (7 famili), predator (9 famili), dekomposer (1 famili). Keanekaragaman (H’) arthropoda dengan pengamatan langsung semi organik yaitu 2,27 dan anorganik yaitu 2,21, sedangkan dengan metode relatif (pitfall Trap) semi organik yaitu 1,76 dan lahan anorganik 1,59.

ENGLISH:

Shallots are a fair amount of vegetables cultivated in the Stone. Onion cultivation in the Torongrejo village of Batu using the concept of semi organic and inorganic farming. Using high pesticide causes fall of arthropod diversity. Arthropod diversity can be used as an indicator of ecosystem stability, so that the study aims to identify arthropods, knowing the importance of diversity the spring onion farm semi organic and inorganic Torongrejo village of Batu.

The research was conducted in the Torongrejo village of Batu and performed identification of arthropods in the laboratory Ecology Biology Department of the State Islamic University Maulana Malik Ibrahim Malang, from June to August 2012. The study was conducted on onion farms covering 600 m2 using the absolute method (direct observation) and the relative method (Pit Fall Trap).

The results on the field of organic spring onions 10 orders 18 families and 1136 individuals include herbivores (8 families), and predators (10 families, while the inorganic soil consists of 9 orders, 17 families and 1153 individuals include herbivores (7 families), predators (9 families), decomposers (1 family). Diversity (H) arthropods by direct observation is semi organic and inorganic 2.27 is 2.21, while the relative method (Pitfall Trap) is semi organic and soil inorganic 1.76 1, 59.
