      Abstract
      Teknik pengolahan air yang dapat digunakan untuk menghasilkan kualitas air yang baik bagi budidaya ikan koi salah satunya adalah dengan penerapan Recirculating Aquaculture System (RAS). Penelitian ini bertujuan untuk menganalisis kesesuaian adsorpsi dari multimedia filter dan karbon aktif yang digunakan dengan model isoterm adsorpsi. Penelitian dilakukan dengan mengukur konsentrasi parameter amonia, nitrit, TSS, alkalinitas, suhu, pH, dan DO pada kualitas air dengan menerapkan beberapa variasi pada ketebalan dan debit multimedia filter. Variasi debit yang digunakan antara lain 45 L/menit dan 22,5 L/menit, serta variasi ketebalan media zeolite yang digunakan antara lain 30 cm, 60 cm, dan 90 cm. Kemudian melakukan analisis isoterm adsorpsi dengan menggunakan model isoterm adsorpsi langmuir, freundlich, temkin, halsey, dan khan. Kualitas air influen dan efluen pada unit filter karbon aktif menunjukan penurunan konsentrasi amonia, nitrit, dan TSS. Dari beberapa variasi yang digunakan, variasi ke-5 (ketebalan zeolite 90 cm dan debi 45 L/menit) merupakan variasi yang terbaik. Model isoterm adsorpsi khan merupakan model yang paling sesuai dikarenakan memiliki tingkat kesesuaian regresi yang paling tinggi.
       
      One of the water treatment techniques that can be used to produce good water quality for koi fish farming is the application of the Recirculating Aquaculture System (RAS). This study aims to analyze the adsorption suitability of the multimedia filter and activated carbon used with the adsorption isotherm model. The research was conducted by measuring the concentration of ammonia, nitrite, TSS, alkalinity, temperature, pH, and DO parameters on water quality by applying several variations on the thickness and discharge of the multimedia filter. Variations in the discharge used included 45 L/min and 22.5 L/min, and variations in the thickness of the zeolite media used were 30 cm, 60 cm, and 90 cm. Then analyze the adsorption isotherm using the Langmuir, Freundlich, Temkin, Halsey, and Khan adsorption isotherm models. The quality of the influent and effluent water in the activated carbon filter unit showed a decrease in the concentration of ammonia, nitrite, and TSS. Of the several variations used, the fifth variation (zeolite thickness 90 cm and debi 45 L/min) is the best variation. Khan adsorption isotherm model is the most suitable model because it has the highest level of regression suitability.
