dc.description.abstractThe study about the diversity of macrozoobenthos had been done in Lau Biang River, Karo District in May to June 2016. The aim of this study is to analyze the diversity of macrozoobenthos due to physical-chemical environment factors in Lau Biang Rivers, Karo District. The study conducted by Purposive Sampling method with 3 different locations based on the activity. Macrozoobenthos collections were conducted by Surber net in 10 plots each locations. The result is 2 phylums, 3 classes, 6 orders, 15 families, and 16 generas of macrozoobenthos. Baetidae genera is the most dominated. Density index was ranged from 1,11 - 17,7 individuals/m2, and the diversity was categorized low. Temperature, water pH and dissolved oxygen were relatively strong affected the diversity of macrozoobenthos.en_US
dc.description.abstractPenelitian mengenai keanekaragaman makrozoobentos telah dilakukan di sungai Lau Biang, Kabupaten Karo pada bulan Mei – Juli 2016. Tujuan dari penelitian ini adalah menganalisis keanekaragaman makrozoobentos dengan faktor fisik-kimia air di sungai Lau Biang Kabupaten Karo. Penelitian dilakukan dengan menggunakan metode Purposive Sampling pada 3 stasiun berdasarkan perbedaan aktivitas. Sampel makrozoobentos diambil dengan menggunakan surber net pada 10 plot di setiap stasiun. Hasil penelitian yang didapat adalah 2 filum, 3 kelas, 6 ordo, 15 famili, dan 16 genera makrozoobentos. Genera Baetidae merupakan genera yang paling banyak dijumpai. Nilai kepadatan yang diperoleh antara 1,11 – 17,7 individu/m2, keanekaragaman tergolong rendah. Suhu, pH air dan kejenuhan oksigen berpengaruh sangat kuat terhadap keanekaragaman makrozoobentos.en_US
