Abstract

Ikan betutu (Oxyeleotris marmorata Bleeker, 1852) merupakan jenis ikan air tawar yang dapat ditemukan salah satunya di Waduk Panglima Besar Soedirman. Penyakit pada ikan dapat disebabkan oleh parasit, salah satunya dari golongan ektoparasit. Serangan ektoparasit dapat mengakibatkan penurunan kualitas ikan, seperti kerusakan pada bagian tubuh ikan (sirip gripis, timbul luka), pertumbuhan lambat dan penurunan berat badan. Penelitian ini tentang keanekaragaman dan kelimpahan ektoparasit pada ikan betutu (O. marmorata Bleeker, 1852) di Waduk PB. Soedirman. Tujuan penelitian ini yakni untuk mengetahui keanekaragaman dan kelimpahan ektoparasit serta mengetahui organ yang paling tinggi tingkat serangan ektoparasitnya pada ikan betutu (O. marmorata Bleeker, 1852) di Waduk PB. Soedirman. Penelitian ini menggunakan metode survey, pengambilan sampel secara purposive random sampling yang dilakukan selama bulan Agustus 2020 sampai September 2020 dalam dua kali pengambilan sampel di Waduk PB. Soedirman dengan tiga titik lokasi (Karang Kemiri, Wanadadi dan Karang Jambe). Jumlah sampel yang didapat yakni 60 ekor dan jenis ektoparasit yang ditemukan adalah Oodinium sp., Dactylogyrus sp. dan Glochidium. Kesimpulan pada penelitian ini, keragaman ektoparasit pada ikan betutu adalah kategori sedang, sebesar 1.06. Kelimpahan ektoparasit tertinggi didapatkan pada Oodinium sp. 45%, kemudian Dactylogyrus sp. 32.2% dan terendah Glochidium sebesar 22.8%. Organ yang paling banyak terinfeksi ektoparasit adalah organ insang yaitu Oodinium sp. sebesar 62.7%, Dactylogyrus sp. 99% dan Glochidium 91.8%.

Abstract

Apis cerana honey bees are members of the order Hymenoptera, Family Apidae, Sub Family Apinae and Genus Apis. A. cerana bees need feed in the form of nectar and flower pollen (pollen). When the dry season occurs, the availability of natural food sources is difficult to obtain, so alternative feed for bees is very important and necessary. This study aims to determine the concentration of sugar solution preferred by A. cerana bees, to determine the distance to the preferred feed source for A. cerana bees and to determine the direction of the preferred feed source for A. cerana bees. The method used in this research is the split-split plot experimental method with the main plot is the direction, the sub plot is the distance, and the sub-plot is the sugar concentration. The sugar concentration used was 0%, 15%, 35%, and 50%. The distances used are 1 m, 4 m and 7 m which are located in 4 cardinal directions from the bee colony. The data obtained were analyzed using descriptive statistical methods, conservative non-parametric Kruskal Wallis (KW) using SPSS software. The results of this study were the concentration of sugar preferred by A. cerana bees, namely the concentration of sugar 50%, the distance of the preferred feed source for A. cerana bees from the beehive, namely a distance of 7 m, and the direction of the preferred source of feed by A. cerana bees from the beehive, namely east direction.
