KARAKTER HABITAT IKAN PARI AIR TAWAR SEBAGAI DASAR PENGELOLAAN DI MIDDLE STREAM SUNGAI MUSI, SUMATERA SELATAN

Abstract

JOSHUA RUBEN BUNGARAN SIMANJUNTAK. Karakter Habitat Ikan Pari Air Tawar sebagai Dasar Pengelolaan di Middle Stream Sungai Musi, Sumatera Selatan. Dibimbing oleh ZAIRION dan AYU ERVINIA. Ikan pari air tawar memiliki nilai ekologis dan ekonomis yang penting di perairan sungai Musi, Sumatera Selatan. Namun, informasi mengenai karakter habitatnya masih terbatas, sehingga penelitian ini dilakukan dengan tujuan untuk menentukan habitat ikan pari air tawar berdasarkan parameter lingkungannya. Penelitian dilakukan secara temporal selama tiga bulan pada Maret hingga Mei 2023 dan secara spasial di tiga stasiun pada bagian middle stream Sungai Musi, yaitu Pulo Kerto, Karang Anyar, dan Plaju. Terdapat 6 spesies ikan pari air tawar di sungai Musi yang tersebar pada Pulo Kerto, Karang Anyar, dan Plaju. Karakter habitat ikan pari air tawar di sungai Musi dicirikan dengan memiliki kedalaman dari 3-10 meter dan substrat bertipe liat. Parameter fisik-kimiawi pada habitat tersebut didapati suhu dan DO yang relatif tinggi, TDS, dan kecerahan yang rendah, serta pH netral cenderung asam. Seluruh spesies ikan pari air tawar di sungai Musi berasosiasi dengan parameter fisik-kimiawi perairan yang ada. Berdasarkan analisis data, tidak ditemukan parameter lingkungan yang spesifik yang menjadi ciri habitat ikan pari air tawar di bagian tengah (middle stream) perairan sungai Musi. Kata kunci: air tawar, habitat, ikan pari, kualitas air, sungai Musi

JOSHUA RUBEN BUNGARAN SIMANJUNTAK. Characterization of Freshwater Stingray Habitats as a Basic for Management in Middle Stream of the Musi River, South Sumatera. Supervised by ZAIRION and AYU ERVINIA Freshwater stingrays hold significant ecological and economic value in the Musi River, South Sumatra. However, information regarding their habitat characterization remains limited. Therefore, this study was conducted to determine the habitat of freshwater stingrays based on environmental parameters. The research was carried out temporally over three months (March to May 2023) and spatially across three stations in the middle stream of the Musi River: Pulo Kerto, Karang Anyar, and Plaju.Six species of freshwater stingrays were found in the Musi River, distributed across Pulo Kerto, Karang Anyar, and Plaju. The habitat characteristics of freshwater stingrays in the Musi River were marked by a depth range of 3–10 meters and clay-type substrate. The physicochemical parameters of the habitat included relatively high temperature and dissolved oxygen, low total dissolved solids and brightness, and a neutral to slightly acidic pH. All freshwater stingray species in the Musi River were associated with the physicochemical parameters of the water. Based on data analysis, no specific environmental parameters were found to be significantly charaterizing the habitat of freshwater stingrays in the middle stream of Musi River.
