Biuret, Urea, prillAbstract
Biuret merupakan hasil samping dalam sintesa pembentukan urea. Kandungan biuret yang tinggi dalam produk urea dapat menjadi racun bagi tanaman sehingga keberadaan biuret harus ditekan. Salah satu faktor terbentuknya biuret adalah temperatur yang tinggi. Penelitian ini bertujuan untuk menentukan temperatur operasi optimum terhadap penurunan kadar biuret dalam urea prill. Analisa dilakukan terhadap enam variabel temperatur operasi 137 oC, 138 oC, 139oC, 140oC, 141oC, dan 142oC. Sampel dari Evaporator berupa produk urea prill diambil dari belt conveyor, kemudian dilakukan uji kandungan biuret menggunakan spektrofotometer dan kadar air urea prill dengan metode aquatitrator. Hasil penelitian menunjukkan bahwa temperatur operasi optimum pada evaporator adalah 138oC, karena mampu menghasilkan kadar biuret yang rendah sebesar 0,798% dengan kadar air yang juga rendah sebesar 0,44%, dan tingkat efisiensi penggunaan steam sebesar 211,541 kg/jam.
