Urea merupakan salah satu pupuk berbasis nitrogen yang paling melimpah dengan proses manufaktur yang berkembang dengan baik dan kemanjurannya dalam meningkatkan ketersediaan nutrisi dan akumulasi senyawa protein dalam tanaman. Salah satu kelemahan penggunaan granul urea sebagai pupuk adalah kelarutannya dalam air yang tinggi dari 119mg/100ml pada 200C. Karena tingginya kelarutan, perkiraan efisiensi penggunaan nitrogen diseluruh dunia hanya 20-35%. Bahan yang digunakan adalah granul urea, dilakukan pemeriksaan bahan baku dan pembuatan tablet ureanya dengan metode kempa langsung, tablet urea yang dihasilkan selanjutnya di evaluasi dan pengujian pelepasan pada media tanah dan lumpur. Dari hasil penelitian diperoleh bahwa tablet urea lebih lama bertahan di media tanah dan lumpur dibandingkan dengan granul urea. Kesimpulan Penggunaan tablet urea lebih efisien dibandingkan granul urea karena dengan merubah bentuk granul urea menjadi tablet urea dapat mengurangi laju kehilangan urea, meminimalkan dampak negatif yang berhubungan dengan penggunaan takaran yang berlebihan dan juga dapat mengurangi dampak pencemaran lingkungan.

The formation of metal nanoparticles (silver, gold, platinum) by biological methods (green synthesis) has advantages over chemical and physical methods because it is easier, faster, simpler, and environmentally friendly. One of the substances used in this method is plant extracts. The presence of secondary metabolites that act as antioxidants such as phenolics and flavonoids play roles in the formation of silver nanoparticles. In this study, phytochemical screening was carried out from several herbal plants as bioreductors in the formation of silver nanoparticles, such as Phyllanthus buxifolius, Pachira aquatica, Peperomia pellucida, Ageratum conyzoides, and Piper crocatum leaf extracts. The total antioxidant content was determined using the modified phenanthroline method, and the total phenolic content determined using the Folin-Ciocalteu method. The formation of silver nanoparticles was carried out by mixing silver nitrate solution with each plant extract. Colloidal silver nanoparticles formed were then measured for their absorption spectra. The results of the antioxidant content of the five consecutive samples were 26,90 ± 0,19; 26,09 ± 0,14; 18,25 ± 0,02; 42,76 ± 0,14; dan 30,94 ± 0,14 mg AA/g, while the total phenolic contents were 48,44 ± 0,45; 21,08 ± 0,92; 17,42 ± 0,27; 57,71 ± 0,47; dan 49,83 ± 0,60 mg GA/g. Silver nanoparticles mediated by Ageratum conyzoides leaf extracts provided the highest absorbance value compared to other plants. The antioxidants and phenolic contained in the extract acts as reducing agent from silver ions into silver nanoparticles.

Productivity of ruminant cattle can be increased by providing non-protein nitrogen, especially urea. Urea not only has benefits as a plant fertilizer, but is also used as a substitute for nitrogen sources for ruminants. The purpose of this research is to use urea more efficiently because urea in the rumen is degraded more quickly to form ammonia so that urea excretion becomes faster in the urine. In this study it was designed so that urea is released in a slow release, its use is more practical and the dosage is correct. The method used is to make urea tablets and then coat them with a coating, characterize the tablets including their shape and urea content, then test the release of the tablets in vitro in rumen fluid. Based on this, the characteristics of the tablets are using Scanning electron microscopy (SEM), Differential Scanning Calorimetry (DSC) and Fourier transform infrared spectroscopy (FTIR) methods. From the results of the study showed that urea tablets fulfilled the tablet evaluation including tests for uniformity in size, weight variation, tablet hardness and friability. Meanwhile, for testing the release of urea tablets in the rumen fluid, it can be seen from testing that 70% of the urea tablets without coating were released, while for the coated urea tablets, only 15% were released in the first minute. Sequentially the release of urea tablets from the first minute with three successive repetitions of the test was 14.641; 15.323 and 14.798 %. Meanwhile, tablets that were not coated in the first minute released as much as 71.257%. For this reason, the manufacture of polycaprolactone-coated slow release urea tablets makes urea more beneficial for ruminants without rapid excretion and lasts longer in the rumen so that rumen microbes take advantage of this nitrogen source to form microbial protein.

Urea is a source of non-protein nitrogen (NPN) which can be used to replace pure protein in ruminants. Urea is easily soluble and is degraded to ammonia by rumen bacteria, thus affecting the quality of ruminants. To increase the utilization of urea as a supplement is to try to slow its release into ammonia in the rumen so that it can be used efficiently by rumen microbes to form microbial protein. Slow release urea tablets as an alternative can control the rate of urea degradation and release of ammonia into the rumen and increase rumen efficiency. This study aims to determine the rate and pattern of release of urea tablets in the rumen so that their use is more practical and the dosage is correct. To maintain ammonia levels in the rumen, an alternative polymer-coated urea slow release tablet was designed. Based on this, it was carried out to manufacture slow release urea tablets with biopolymer polylactic acid (PLA) coating in the rumen fluid of ruminants. Furthermore, an in vitro evaluation was carried out by measuring pH into rumen fluid and measuring NH3 by UV-Vis spectro analysis at a wavelength of 630 nm. The results of the test for urea release in the rumen in formulas 1, 2 and 3 were 75.133%, 76.076% and 74.051% respectively, while the release of urea in uncoated urea tablets was 96.384%, these results indicate that tablets with lactic acid coated polyacid last longer. release compared to urea tablets without biopolymer coating.
