Abstract
Haris et al, 2019. The Analysis of Water Suitability for Floating Net Sprouts in Sirah Pulau Padang, Ogan Komering Ilir District, South Sumatra Province. JLSO 8(1):20-30.The purpose of this study is to analyze the level of water suitability of the floating net sprouts in sirah pulau padang, ogan komering river, Serdang Menang Village, OKI South Sumatra Regency based on water physical and chemical parameters. This study was conducted on July - August 2018 at the Komering River, Ulak Jermun village, Terusan Menang Village, and Mangun Jaya Village, OKI District, South Sumatra. The data of sampling was divided into 3 stations, they were; station 1 was Ulak Jermun Village (3 ° 18'45.48 "LS and 104 ° 53'5.32" BT), station 2 was Terusan Menang Village (3 ° 17'14.13 "LS and 104 ° 52'46.78 "BT), and station 3 was Mangun Jaya village (3 ° 18'14.92" LS and 104 ° 52'59.48 "BT). The data of Samples were tested at the chemical laboratory in Palembang Public Water Fisheries and Extension Research Institute directly. The results of the study was for Station 1, Station 2, and Station 3 with a value was 48% with a good feasibility information. The results of measurements of water quality parameters, the pH was about 6.6 - 6.7, temperature was about from 24., 53 - 26.93oC, DO 3.93 - 4.36 mg / l, ammonia was about 0.78 - 0.16 mg / l, water brightness was about from 34.67 - 43.33 cm, CO2 4.53 - 5.03 mg / l, depth 2.36 - 2.47 m, current velocity was about 0.38 - 0.44 m / s, nitrate was about 0.37 - 0.439 mg / l, phosphate was about 0.009 - 0.225 mg / l and the bottom substrate of water was mud.

Summary
Waktu dan Tempat Penelitian ini dilakukan di sekitar perairan desa Ulak Jermun, Desa Mangun Jaya dan Desa Terusan Menang kecamatan Sirah Pulau Padang Kabupaten Ogan Komering Ilir Sumatera Selatan yang banyak budidaya ikan dalam keramba. Setiap parameter diberi bobot sesuai peranannya bagi kelayakan budidaya perikanan dengan diberi nilai 1 – 3. Total nilai kesesuaian actual dibagi total nilai kesesuaian maksimal untuk menentukan tingkat kelayakan kawasan budidaya perikanan yang dapat dinyatakan (Praptokardyo dan Wellem, 2008) : 80 – 100 % = Kelayakan sangat baik (Excelent). Kegiatan evaluasi perlu dilakukan atas kesesuaian biofisik, smberdaya dan lingkungan bagi produksi budidaya perikanan system KJA). Kesesuaian lahan didasarkan pada parameter biofisik yang dievaluasi dan diberi nilai atas dasar kriteria: S1 = Sangat sesuai. Parameter kesesuaian lahan perlu diberikan nilai peranannya bagi fungsi produksi dengan pembobotan [3, 2], dan 1 sesuai dengan peranan parameter yang bersangkutan. Kesesuaian lahan bagi keramba jaring apung (KJA) ditentukan oleh parameter kualitas air (pH, Suhu, DO, Arus air, Amonia, Nitrat, CO2, Subtrat Dasar, Kedalaman, Kecerahan) dengan kriteria S3, S2, S1, N1, dan N2 dengan nilai berturut – turut [3, 4, 5, 2], dan 1. Setiap parameter diberikan bobot peranannya bagi pengembangan usaha antara 1 – 3
