ABSTRAK
Pembuatan pupuk slow release fertilizer bertujuan untuk membuat pupuk N lebih lambat tersedia bagi tanaman. Dalam penelitian ini pupuk slow release fertilizer menggunakan perpaduan pupuk granul organik dan Urea yang diberikan perekat dari polimer alami yaitu lateks. Penelitian dilakukan dengan menggunakan rancangan acak kelompok non faktorial. Dengan faktor penggunakan pupuk urea sebagai konkrol dan pupuk slow release fertilizer dengan konssentrasi larutan perekat yaitu tanpa lateks, lateks 4%, lateks 8%, lateks10%, dan lateks 20%. Tes lebih lanjut menggunakan uji F 1% dan 5%, bila ada berbedaan dilanjukan uji BNJ 5%. Hasil penelitian menunjukkan bahwa perlakuan pupuk slow release fertilizer dengan konssentrasi larutan perekat belum bisa menyamai pupuk urea yang diaplikasikan dua kali pada budidaya tanaman padi (Oriza sativa). berpengaruh nyata terhadap parameter pengamatan tinggi tanaman umur 45 HST, tinggi tanaman umur 60 HST, jumlah anakan persempel, dan jumlah anakan produktif persempel. Pada para meter panjang malai dan 1000 benih berbedah tidak nyata. Perlakuan terbaik tetap menggunakan pupuk urea dengan dua kali aplikasi dan untuk pupuk slow release fertilizer perlakuan lateks 20% hampir menyamai penggunaan pupuk urea.
Kata kunci: Pupuk slow release fertilazer, Lateks, dan Padi.

Abstract
Making slow release fertilizer fertilizer N aims to create more slowly available to plants. In this study, slow release fertilizer fertilizer uses a combination of organic granule fertilizer and urea which is given an adhesive from natural polymer namely latex. The study was conducted using a non factorial randomized block design. With the factor of using urea fertilizer as a concubine and slow release fertilizer with the concentration of adhesive solution that is without latex, 4% latex, 8% latex, 10% latex, and 20% latex. Further tests use the F test of 1% and 5%, if there is a difference, then the BNJ test is 5%. The results showed that the treatment of slow release fertilizer with concentration of adhesive solution could not match urea fertilizer which was applied twice incultivation rice(Oriza sativa). significant effect on the observation parameters of plant height at 45 HST, plant height at 60 HST, number of tillers, and number of productive tillers. At the length of the panicle and 1000 seeds dissected is not real. The best treatment still uses urea fertilizer with two applications and for slow release fertilizer fertilizer latex treatment 20% almost equals the use of urea fertilizer.
