摘要：Penelitian ini dilakukan untuk mempelajari kelarutan Si tersedia antara trass bakar dan non bakar dan penentuan formula terbaik untuk dijadikan sebagai pupuk silika. Penelitian ini dilakukan di Laboratorium Kimia dan Kesuburan Tanah, Departemen Ilmu Tanah dan Sumberdaya Lahan, Institut Pertanian Bogor. Rancangan Percobaan yang dilakukan adalah split plot dengan petak utama terdiri dari trass bakar dan non bakar, dan anak petak terdiri dari dosis trass yang dikombinasikan dengan CaCO3 yaitu 100% trass, 83.33% trass+16.67 CaCO3, 66.67.% trass +33.33% CaCO3, masing-masing perlakuan diulang sebanyak tiga kali, sehingga total satuan percobaan ada 18. Hasil penelitian menunjukkan bahwa trass bakar menunjukkan hasil kelarutan silika tersedia tertinggi dibandingkan trass non bakar. Kombinasi 83% trass+ 17% CaCO3 menunjukkan Si tersedia tertinggi yaitu 120.02 ppm, 72.67 ppm dan 53.43 ppm berturut-turut dengan pengekstrak ammonium asetat pH 4.8, 0.5 M HCl dan H2O.
其他摘要：This research was conducted to determine the available Si between burned trass and unburned trass, also to determine the best formula to be used as silica fertilizer. This research was conducted at the Laboratory of Soil Chemistry and Fertility, Department of Soil Science and Land Resources, Faculty of Agriculture, IPB University. The experimental design was the split-plot with the main plot consisted of burned trass and unburned trass, and the subplot consisted of combination dosage of trass and CaCO3, those were 100% trass, 83.33% trass + 16.67 CaCO3, 66.67.% trass + 33.33% CaCO3, each treatment was replicated three times, resulting in 18 experiment units. The result showed that the burned trass showed the highest available Si compared to the unburned trass. The combination of 83% trass + 17% CaCO3 showed the highest available Si of those were 120.02 ppm, 72.67 ppm and 53.43 ppm, respectively with extractant of ammonium acetate pH 4.8, 0.5 M HCl and H2O.
