Abstract
Fertilizer is one of the most important products of the agrochemical industry. Urea is a fertilizer that contains high levels of nitrogen (N) of 45% - 56%. The nitrogen element is very beneficial for plants for growth and development. The strategy is to increase efficiency by using environmentally friendly fertilizers. An innovation that can be made to increase the efficiency of fertilizer absorption and reduce environmental damage is the encapsulation process. The encapsulation method that can be used is crosslink emulsion. This method is easy and simple, and can be used for both soluble and insoluble mixtures. In determining the %Yield, the effect of 4% chitosan concentration produced the largest %yield with 97.28% and the stirring speed on the %Yield also produced 97.28% but only the oil variety had the largest %yield of 94.33% which was produced by the oil variation 300 ml. The lowest nitrate content produced by this fertilizer is 0.205 mg/L while the highest is 1.802 mg/L. The lowest nitrite content was produced from controlled release urea fertilizer which used a concentration of 3% with a release time of day 1, namely 0.002 mg/L and the highest was 0.074 mg/L. The highest content of ammonia was produced by soaking controlled release urea fertilizer with a concentration of 2% on the 30th day, it was 26.978 mg/L.

| Additional Information: | Pupuk merupakan salah satu produk yang paling penting dari industri agrokimia. Urea adalah pupuk yang mengandung nitrogen (N) berkadar tinggi sebesar 45% - 56%. Unsur nitrogen tersebut sangatlah bermanfaat bagi tanaman untuk pertumbuhan dan perkembangan. Adapun strategi yang dilakukan untuk meningkatkan efisiensi dengan menggunakan pupuk yang ramah terhadap lingkungan. Inovasi yang dapat dilakukan untuk meningkatkan efisiensi penyerapan pupuk dan mengurangi kerusakan lingkungan adalah proses enkapsulasi. Metode enkapsulasi yang dapat digunakan adalah crosslink emulsi. Metode ini mudah dan sederhana, serta dapat digunakan untuk campuran yang larut dan tidak dapat larut. Pada penentuan %yield pengaruh konsentrasi kitosan 4% dihasilkan %yield terbesar sebesar 97,28 % dan pada kecepatan pengadukan terhadap %yield nya menghasilkan sebesar 97,28 %. Kandugan nitrat terendah yang dihasilkan yaitu 0,205 mg/L sedangkan kandungan tertinggi adalah 1,802 mg/L. Kandungan nitrit terendah yang dihasilkan dari pupuk urea pelepasan terkendali sebesar 0,002 mg/L dan tertinggi adalah 0,074 mg/L. Kandungan tertinggi amonia yang dihasilkan oleh perendaman pupuk urea pelepasan terkendali dengan konsentrasi 2% pada hari ke-30 yaitu sebesar 26,978 mg/L. | ||||||
