摘要
控释尿素肥是提高植物对养分吸收效率的一种解决方案，而且更环保。本研究的目的是测定控释尿素肥的产量和吸水率，并分析硝酸盐、亚硝酸盐和氨的含量作为环境污染参数。以壳聚糖为基质，采用乳液交联法制备了控释尿素肥料。将尿素溶解在壳聚糖中，然后加入油中搅拌形成乳液。然后，以戊二醛饱和甲苯(GST)为交联剂，缓慢滴注，连续搅拌2小时。对载尿素壳聚糖微球(控释尿素肥)进行了干燥分析。此外，还测定了尿素的收率、吸水率以及硝酸盐、亚硝酸盐和氨的分析。控释尿素肥产量为91.3 ~ 97.28%，吸水率为78.87 ~ 91.61%。通过对硝酸盐、亚硝酸盐和氨的分析，得出壳聚糖微球中含有尿素肥料更环保的结论。关键词:控释尿素，壳聚糖，环保型，乳液交联，肥料摘要pupuk尿素pelepasan terkendali merupakan salah satu solusi untuk meningkatkan efisiensis penyerapan nutrisi oleh tanaman dan lebih ramah lingkungan。土juan penpenelitian ini adalah menentukan产量丹达亚serap空气dari pupuk尿素pelepasan terkendali丹分析kandungan硝基，硝基，丹氨sebagai参数pencemaran lingkungan。Pupuk尿素pelepasan lambat分布在menggunakan方法交联乳剂登甘kitosan sebagai基质。尿素dilarutkan dalam larutan kitosan kemudian dimasukkan ke dalam minyak dan diaduk untuk membentuk乳剂。Selanjutnya，戊二醛饱和甲苯(GST) sebagai交联剂diteteskan secara perlahan和terus diaduk selama 2 jam。Kitosan mirosfer berisi尿素(pupuk urea pelepasan terkendali)。三叶草、梅尼图坎产量、大叶草、丹孟亚硝、丹孟亚硝、丹氨水、丹氨水、尿素阳利。Pupuk urea pelepasan terkendali diperoleh产率sebesar 91,3 - 97,28%， daya serap air sebesar 78,87 - 91,61%。硝酸钾分析，硝酸钾，丹氨达pupuk menypulkkan bahwa pupuk尿素pelepasan terkendali lebih ramah lingkungan。Kata kunci:尿素pelepasan terkendali, Kitosan, Ramah lingkungan，交联乳剂，Pupuk
Modifikasi Pupuk Urea Pelepasan Terkendali dan Pengaruhnya terhadap Lingkungan
Controlled release urea fertilizer is one solution to increase the efficiency of nutrient absorption by plants and is more environmentally friendly. The aims of this study was to determine the yield and water absorption of controlled release urea fertilizer and analyze the content of nitrate, nitrite, and ammonia as environmental pollution parameters. Controlled release urea fertilizer was prepared using the emulsion crosslinking method with chitosan as the matrix. Urea was dissolved in chitosan then added in oil and stirred to form an emulsion. Next, glutaraldehyde saturated toluene (GST) as a crosslinker was dripped slowly and then continuously stirred for 2 hours. Urea loaded-chitosan microspheres (controlled release urea fertilizer) were dried and analyzed. Furthermore, the yield, water absorption, and analysis of nitrate, nitrite, and ammonia from the released urea was determined. Controlled release urea fertilizer obtained yield was 91.3–97.28%, water absorption of 78.87–91.61%. Analysis of nitrate, nitrite, and ammonia from the study concluded that urea fertilizer contained in chitosan microspheres is more environmentally friendly.
