Abstract

Salah satu bahan pangan yang banyak dikonsumsi di Indonesia ialah ikan. Ikan mengandung kandungan protein yang tinggi dan memiliki kandungan lemak di bawah 5% sehingga lebih sehat untuk dikonsumsi dibandingkan ayam. Salah satu jenis ikan yang berpotensi dibudidayakan adalah ikan lele (Clarias sp) karena mudah untuk dibudidayakan dan dapat tumbuh dalam waktu yang relatif cepat. Permasalahan yang timbul saat pembudidayaan ikan lele adalah turunnya kualitas air kolam karena adanya pencemaran yang berasal dari kotoran lele dan sisa pakan.Upaya pengelolaan limbah dapat dilakukan melalui fitoremediasi. Pada penelitian ini digunakan tumbuhan air yang sering dianggap sebagai gulma tetapi diketahui memiliki kemampuan fitoremediasi yakni enceng gondok (Eichhornia crassipes), kangkung (Ipomea aquatica), dan apu-apu (Pistia stratiotes). Berdasarkan hasil penelitian, diketahui bahwa ketiga tumbuhan air tersebut mampu menjaga kualitas air kolam dan meningkatkan sintasan ikan lele.

Abstract

Magnetite, chemically represented as Fe3O4, is an opaque substance characterized by its black coloration. It possesses a significant saturation magnetization value, denoting a substantial magnetic strength compared to alternative materials. Magnetite (Fe3O4) has significant use across several domains, including its deployment as a catalyst and sensor in the medical sector, such as drug delivery, hyperthermia therapy, and magnetic resonance imaging (MRI). The synthesis of magnetite (Fe3O4) can be achieved using several methodologies, such as solvothermal, sol-gel, solid state, reverse micelle, microwave plasma synthesis, freeze drying, ultrasound irradiation, hydrothermal, and coprecipitation techniques. The co-preparation technique is extensively employed for magnetite synthesis due to its simplicity, ease of usage, and ability to generate magnetic particles at the nanoscale scale without elevated temperatures. The outcome of the coprecipitation process is influenced by various factors such as the nature of the salt, molar ratio, pH level, stirring rate, and reaction temperature. This article aims to examine the impact of many factors, including the salt type, molar ratio, pH level, stirring rate, and reaction temperature, on the production of Magnetite (Fe3O4) through coprecipitation. It was found that Magnetite (Fe3O4) synthesis can produce nanoparticle size material with great magnetic power, namely at pH 8, temperature 70°C, and stirring rate of 10,000 rpm by using FeCl3 and FeCl2 as precursors Fe3+ and Fe2+ with a ratio of 1.5:1 and using precipitating base NH4OH.
