Pemupukan merupakan upaya untuk meningkatkan ketersediaan hara dalam tanah guna menunjang pertumbuhan tanaman yang optimal. Sistem usahatani padi sawah intensif di Indonesia, sejak era revolusi hijau hingga sekarang tidak terlepas dari peran pupuk kimia yang bernama urea. Penelitian bertujuan untuk mengetahui pengaruh pemberian bahan penghambat nitrifikasi alami terhadap pertumbuhan, hasil dan efisiensi pemupukan N pada tanaman padi. Penelitian rumah kaca untuk mengetahui efektivitas pengunaan pupuk N + nitrat inhibitor (NI) alami dilakukan di rumah kaca Fakultas Pertanian Universitas Gadjah Mada. Rancangan yang digunakan adalah Acak Lengkap dengan perlakuan sebagai berikut; N0 = tanpa urea tanpa NI (kontrol); N1 = urea tanpa NI; N2 = urea + NI dari bubuk kulit bakau pada dosis 20 % dari urea; N3 = urea + NI dari bubuk kulit bakau pada dosis 30 % dari urea; N4 = urea + NI dari bubuk biji mimba pada dosis 20 % dari urea, dan N5 = urea + NI dari bubuk biji mimba pada dosis 30 % dari urea, diulang sebanyak 4 kali. Hasil penelitian menunjukkan bahwa (1) Perlakuan NI rata-rata mampu mempertahankan nilai kandungan klorofil pada daun padi pada umur 60 hst berada diatas batas kritis, (2) Perlakuan terbaik adalah bahan NI yang berasal dari serbuk biji Nimba dengan takaran 20 % dari dosis urea yang diberikan, yang memberikan kenaikan hasil sebesar 9,6 %, dan (3) Penggunaan pupuk urea + serbuk biji Nimba 20 % lebih efektif dengan nilai efektivitas (RAE) sebesar 34 % dan efisiensi agronomi (AE) sebesar 50 g g-1 dan lebih tinggi dibandingkan perlakuan yang lain.

The experiment of addition of N on Liquid Organic Fertilizer (LOF) for ratoon rice crop has been done In Padang City, September 2017 to January 2018. The aimed was to obtain an appropriate combination of nitrogen administration to LOF to ratoon rice crop. The experiment was arranged in a split plot, the main plot being a pruning consisting of 2 levels ie; not pruned and pruned. The subplot of fertilizer foliar consists of 4 types namely; 0 (F1); 800 mg L-1 Urea (F2); 25 ml L-1 + Urea (F3); 50 ml L-1 POC + Urea (F4), 3 replications. Data were analyzed statistically by using ANOVA α 5%, if treatment had real effect done with BNT test α 5%. Parameters include; weight of crop forage, plant height, percentage of productive tillers, flowering age and harvest, straw and paddy production per hectare. The results was that administering 800 mg L-1 of single N fertilizer from Urea or adding it to LOF was not favorable for growth and yield of ratoon rice. Pruning did not reduce grain yield reaching 5.37 t ha-1 , and earn farming can still be offset by the existence of HPT of 3.63 t ha-1 .

This study aims to determine the effect of adding microorganic mineral and Silage of cassava leaves to TDN (Total Digestible Nutrient) and digestible energy based on palm oil waste on heifer. The study was conducted in March-May 2018 at the Animal Nutrition and Feed Laboratory, Department of Animal Husbandry, Faculty of Agriculture, University of Lampung. The material of this study using 9 Ongole cattle grade and grouping based on body weight. This study used a randomized block design with 3 treatments and 3 replications. The research treatment consisted of R0 (ration control), R1 (R0 + organic minerals (Zn 40 ppm, Cu 10 ppm, Cr 0.30 ppm, and Se 0.10 ppm) and R3 (R1 + 15% cassava leaves (branched amino acid source / brand chain amino acid) The results showed that: The provision of rations based on oil palm waste significantly affected TDN (Total Digestible Nutrient) and did not significantly affect digestible energy in the Ongole Breeders cow, fermented waste palm oil rations (R2) p...
BRIKET ARANG TANDAN KOSONG KELAPA SAWIT DAN SEKAM PADI DENGAN PEREKAT Palm Oil Mill Effluent : OPTIMASI LAMA WAKTU SLOW PYROLISIS, 2019
Tandan kosong kelapa sawit merupakan limbah dari pengolahan kelapa sawit dan sekam padi adalah limbah dari pengolahan beras, keduanya merupakan limbah dari industri yang sebenar nya bisa diolah lebih lanjut. Untuk menambah nilai dari tandan kosong kelapa sawit dan sekam padi maka diolah kembali menjadi briket arang yang dapat di jadikan energi biomassa alternatif. Penelitian ini bertujuan mencari variasi optimum dari briket arang dengan menggunakan variasi lama waktu pirolisa menggunakan drum bekas selama 3, 4, 5, dan 6 jam dengan penambahan kapur 1% serta mengunakan perekat dari Palm Oil Mill Effluent.Variasi lama waktu pirolisa dengan hasil optimum pada penilitian kali ini terdapat pada variasi lama waktu 6 jam dengan nilai kadar air (4.2016 %), Kadar abu (27.1722%), Kadar Karbon terikat (56.8925%) , nilai drop test (18.6593%) dan kadar zat menguap (15.9353 %).

This research aimed to study the effect of different forage composition in diet on nitrogen balance andmicrobial population of Bali cattle. Randomized Block Design consisted of four feed treatments with 3block of weight live as replicates were used in this study. Body weight of male bali cattle used rangedbetween 181-265 kg. These four treatments based on dry matter were: A (45% elephant grass + 0% ricestraw + 15% glyricidia + 10% calliandra + 30% concentrate); B (30% elephant grass +10% rice straw + 20%glyricidia + 10% calliandra+ 30% concentrate) ; C (15% elephant grass +20% rice straw + 25% glyricidia+10% calliandra + 30% concentrate) and D (0%elephant grass + 30% rice straw + 30% glyricidia + 10%calliandra+ 30% concentrate) . Variables measured were nitrogen balance and rumen microbial population.The collected data were analyzed by analysis of variance. The result showed that nitrogen intake in cattlefed with diet C was significantly (P 0.05) among all treatments, but the popula...

This study aims to determine the effect of the C/N ratio of a mixture of dairy cow dung and kirinyuh leaves on the quality of extraction or Liquid Organic Fertilizer (POF). The treatment consisted of a mixture of dairy cow manure and kirinyuh leaves with different C/N, namely P1=16, P2=18, P3=20, P4=22. The treatment was decomposed for 14 days then extracted and incubated for 14 days. Observations included a decrease in C-organic content (%), total N-total (%), C/N ratio, P content (%), K content (%), the number of P-solvent bacteria (CFU/ml), Azosprillium (CFU/ ml) and Azotobacter (CFU/ml). The results showed that the effect of the C/N ratio only had a significant effect on the N parameter of composting where the best results were seen at a C/N ratio of 16. Meanwhile for the POC quality the parameters C, N and P had no significant effect, while for K parameter, total of Psolubilizing bacteria, Azosprillium and Azotobacter had a significant effect. The highest levels of K and the total of Azotobacter were found at the initial C/N ratio of 16. Meanwhile, the highest total of P-solubilizing bacteria and the highest total of azosprillium were found at the initial C/N ratio of 22. Therefore an initial C/N ratio of 16 is recommended for composting dairy cow faeces. with kirnyuh leaves. While the extraction results are recommended to be focused on making biological fertilizers.
