| Abstrak (Bhs. Indonesia) | Penelitian ini bertujuan untuk: (1) mengetahui pengaruh campuran pupuk organik hayati dan pupuk kimia bersamaan dengan metode konservasi lahan terhadap hasil kentang, (2) mengetahui pengaruh campuran pupuk organik hayati dan pupuk kimia bersamaan dengan metode konservasi lahan terhadap laju erosi lahan dan (3) mengetahui hubungan antara hasil kentang dan laju erosi dengan perlakuan pupuk organik hayati dan pupuk kimia bersamaan dengan metode konservasi lahan. Penelitian dilaksanakan di Kawasan Kaligua, Kecamatan Paguyangan, Brebes dan Laboratorium Ilmu Tanah Fakultas Pertanian, Universitas Jenderal Soedirman. Penelitian berlangsung selama 9 bulan dari bulan Maret 2017 sampai Desember 2017. Penelitian menggunakan Rancangan Acak Kelompok Lengkap dengan 3 faktor dan 3 kali ulangan, yaitu 1) pupuk organik (P) dengan 6 taraf yaitu P1 (kontrol), P2 (POH 20 ton/ha), P3 (POH 15 ton/ha), P4 (POH 10 ton/ha), P5 (POH 5 ton/ha) dan P6 (POH 2,5 ton/ha); 2) pupuk kimia (K) dengan 4 taraf yaitu K1 (kontrol), K2 (dosis anjuran urea 300 kg/ha, SP-36 500 kg/ha, 300 kg KCl) + 200 kg kapur, K3 (1/2 dosis anjuran) + 200 kg kapur dan K4 (1/4 dosis anjuran) + 200 kg kapur dan 3) lereng dengan 3 taraf yang terdiri dari L1 (bedengan kontrol), L2 (bedengan sejajar kontur miring 10%) dan L3 (bedengan sejajar kontur). Variabel yang diamati yaitu tinggi, jumlah daun, porositas, C organik, permeabilitas dan total produksi. Hasil penelitian menunjukkan bahwa hasil kentang berbanding terbalik dengan laju erosi, semakin tinggi laju erosi, maka hasil kentang akan semakin rendah dan sebaliknya. |

| Abtrak (Bhs. Inggris) | This research aims to: (1) find out the influence of mixture of biological fertilizer and chemical fertilizer in conjunction with methods of land conservation against the results of the potatoes, (2) find out the influence of mixture of biological fertilizer and chemical fertilizer in conjunction with method of land conservation against the pace of erosion of the land and (3) find out the correlation between production of potatoes and the pace of erosion of the land with the influence of mixture of biological fertilizer and chemical fertilizer in conjunction with land conservation metdods. The research was carried out in the area of Kaligua, Paguyangan distric, Brebes and soil science laboratory the Faculty of Agriculture, Jenderal Soedirman University. The research lasted for 9 months from March 2017 until December 2017. This research used a Randomized Complete Design Group with 3 factors and repeats three times, i.e. 1) biological fertilizer (P) with 6 levels i.e. P1 (control), P2 (POH 20 tons/ha), P3 (POH 15 tons/ha), P4 (POH 10 tons/ha), P5 (POH 5 tons/ha), and P6 (POH 2.5 ton/ha ); 2) chemical fertilizers (K) with 4 levels i.e. K1 (control), K2 (the dose recommended by 300 kg/ha of Urea, SP-36 500 kg/ha, 300 kg of KCl) + 200 kg of lime, K3 (1/2 dosage recommendations) + 200 kg lime and K4 (1/4 dosage recommendations) + 200 kg lime and 3) the slopes with 3 levels i.e. L1 (Unidirectional beds slopes), L2 (Seedbed contour parallel with 10% slant) and L3 (Seedbed contour parallel). The observed variables i.e. height, number of leaves, porosity, permeability, organic carbon and total production. The results of this research indicate that potato yield is inversely proportional to the pace of erosion. The results showed that the potato yield is inversely proportional to the pace of erosion, when the pace of erosion is higher, then the potato yield will be lower and vice versa. |
