| Judul Artikel | Aplikasi Zeolit Alam pada Berbagai Kadar Nitrogen dan Tinggi Genangan Air terhadap Efisiensi N dan Hasil Padi Sawah |
| Abstrak (Bhs. Indonesia) | ABSTRAK Produktivitas padi sawah nasional Indonesia dalam skala regional cukup tinggi dan menonjol dibandingkan dengan negara-negara lainnya di Asia, kecuali Cina, Jepang, dan Korea. Namun demikian sistem pengelolaan yang kurang tepat menyebabkan menurunnya produktivitas tanah sehingga produksi tanaman tidak optimal. Usaha untuk mengatasi hal tersebut dapat dilakukan melalui pemakaian zeolite serta komposisi pupuk yang sesuai. Penelitian ini bertujuan untuk 1) Mengetahui pengaruh macam jenis zeolite tehadap efisiensi N dan hasil padi, 2) Mengetahui pengaruh komposisi N-Zeolite tehadap efisiensi N dan hasil padi 3) Mengetahui pengaruh tinggi genangan air tehadap efisiensi N dan hasil padi. Penelitian dilaksanakan pada bulan Oktober 2017 sampai Januari 2018 di Fakultas Pertanian Universitas Jenderal Soedirman. Percobaan ini menggunakan Rancangan Acak Kelompok (RAKL), terdiri dari tiga faktor perlakuan. yaitu tinggi genangan air (macak-macak; ketinggian 3-4 cm), jenis zeolit alam (Zeolit tidak termodifikasi; Zeolit termodifikasi) dan komposisi N-Zeolit (10 zeolit : 1 urea; 20 zeolit : 1 urea; 30 zeolit : 1urea; 40 zeolit : 1 urea; 50 zeolit : 1 urea). Percobaan menggunakan 20 kombinasi perlakuan dan ditambah 2 kontrol yang diulang 3 kali sehingga diperoleh 66 unit percobaan.

| Abtrak (Bhs. Inggris) | ABSTRACT The productivity of Indonesia's national lowland rice on a regional scale is quite high and prominent compared to other countries in Asia, except China, Japan and Korea. However, the inappropriate management system causes a decrease in soil productivity so that crop production is not optimal. Efforts to overcome this can be done through the use of zeolite and the appropriate fertilizer composition. This study aims to 1) Determine the effect of zeolite types on the efficiency of N and rice yield, 2) Determine the effect of N-Zeolite composition on N efficiency and yield of rice 3) Determine the effect of high water inundation on N efficiency and rice yield. The research was conducted from October 2017 to January 2018 at the Faculty of Agriculture, Jenderal Soedirman University. This experiment uses a Randomized Block Design (RAKL), consisting of three treatment factors. namely high waterlogging (macakmacak; height 3- 4 cm), type of natural zeolite (unmodified zeolite; modified Zeolite) and N-Zeolite composition (10 zeolites: 1 urea; 20 zeolites: 1 urea; 30 zeolites: 1urea; 40 zeolites: 1 urea; 50 zeolites: 1 urea). The experiment used 20 treatment combinations and added 2 controls which were repeated 3 times to obtain 66 experimental units. The variables observed covered the number of pithy grains, the number of empty grains, the wet weight of unhulled rice, the empty wet weight of unhulled rice, the dry weight of unhulled rice, the dry weight of unhulled grain, and the efficiency of N. The results of the study showed that zeolite had an effect on the number of pithy grains. The average number of rice grains that were given the modified zeolite was more than the number of rice grains that were given unmodified zeolite. The rice plants that were modified with zeolite had a mean of 932.40 grains while the unmodified zeolite rice plants had a mean of 532. 40 grains s; zeolite types affect the wet weight of rice grains. The mean wet weight of rice grains with modified zeolite was greater than the wet weight of the rice grains of rice which were given unmodified zeolite. The rice plants that were given zeolite were modified to have a mean of 29.00 g / clump while the rice plants with dubere zeolite were not modified. has a mean of 25.90 g / clump. ; and the type of zeolite has an effect on the dry weight of pithy grains. The mean wet weight of rice grains of rice plants with modified zeolite was greater than the wet weight rice grains that were given zeolite were not modified, the rice plants which were modified with zeolite had a mean of 23.80 g / clump, while the unmodified zeolite rice plants had a mean of 20.60 g / clump. The composition of N-Zeolite affects the number of pithy grains.
