Abstract


Kandungan nitrat, nitrit, dan ammonia dalam lingkungan hasil dari pelepasan pupuk urea konvensional menjadi parameter terhadap pencemaran lingkungan. Pupuk urea pelepasan terkendali diharapkan mampu mengurangi pencemaran linkungan karena mampu mengurangi kandungan nitrogen disebabkan oleh meningkatnya efisiensi penggunaan nutrisi oleh tanaman. Tujuan penelitian ini adalah menganalisis kandungan nitrat, nitrit, dan ammonia dari release pupuk urea pelepasan terkendali dalam medium air. pembuatan pupuk urea pelepasan terkendali menggunakan metode crosslink emulsi. Pupuk urea pelepasan terkendali yang terbentuk dilakukan uji release dalam medium air (aquadest). Medium release kemudian dianalisis untuk mengetahui kandungan nitrat, nitrit, dan ammonia sebagai parameter pencemaran lingkungan. Hasil analisis menunjukan bahwa kandungan nitrat dan nitrit yang di uji release mulai 1 – 30 hari masih dibawah ambang batas. Sedangkan kandungan ammonia seluruh variabel masih tinggi. Hal ini disebabkan kemungkinan kondisi medium release yang digunakan berupa aquadest dengan pH netral sehingga banyak terbentuk ammonia.
