2014 | Skripsi | BIOLOGISerangga air merupakan kelompok serangga yang sebagian hidupnya berada di badan air. Serangga air termasuk dalam makrozoobentos. Serangga air sangat penting dalam sistem ekologi karena berbagai alasan. Serangga air adalah bioindikator dalam badan air seperti sungai. Kali kuning adalah sungai yang terletak di bagian selatan Gunung Merapi, termasuk dalam Kecamatan Cangkringan, Kabupaten Sleman, Provinsi D.I Yogyakarta. Kali kuning merupakan salah satu sungai yang dilewati aliran lahar hujan ketika Gunung Merapi meletus, dengan demikian maka terjadi perubahan lingkungan di Kali Kuning. Tujuan Penelitian ini untuk mengetahui keanekaragaman dan potensi peranan serangga air di ekosistem. Peneltian menggunakan metode Purposive Random Sampling. Pengambilan sampel menggunakan jaring Surber. Sampel yang diperoleh diidentifikasi dan dianalisis menggunakan indeks Shanon-Wiener. Serangga air yang diperoleh di kelompokan pada 6 Ordo terbagi dari 10 Famili dan 4 Genus. Indeks keanekaragaman Shanon-Wiener H’ : 3,6 menunjukan keanekaragaman serangga air yang tinggi di hulu kali Kuning tinggi. Berdasarkan SIGNAL 2 grade, serangga air anggota Ordo Ephemeroptera, Trichoptera dan Coleoptera yang ditemukan bersifat sangat sensitif dan sensitif dapat digunakan sebagai indikator kualitas air. Kali Kuning dalam kondisi perairan yang baik
Aquatic insects are groups of insects that most of their life in the water body. Aquatic insects are part of macrozoobenthos. Aquatic insects are very important roles in the ecological system due to various reasons. Insects are bio-indicators of water in water bodies such as rivers. Kali Kuning is a river located in the Southern part of Merapi Mount, included in Cangkringan, Sleman District, Yogyakarta Province. Kali Kuning is one of the times through which the river flews lava from the Merapi Mount when the Merapi Mount erupted, and thus a change in the environment at Kali Kuning. The aims of the study were to determine the diversity and the potential roles of aquatic insects in the Kali Kuning ecosystem. The research method used purposive random sampling method. The sampling of the data was conducted by Surber nets. The samples obtained were identified and analyzed using the Shannon-Wiener index. The result consist of 6 Orders, 10 Families and 4 Genus were founded. According to the Shannon-Wiener diversity index of (H'), the diversity of aquatic insects in the upper Kali Kuning was higher than the bottom part of the river with value of H’ was 3,6. By using SIGNAL 2 grade, Order Ephemeroptera, Trichoptera and Coleoptera were grouped to be very sensitive and a sensitive insect therefore those can be used as indicator for water quality. It can be concluded that Kali Kuning was in good water conditions
