| Abstrak (Bhs. Indonesia) | Masalah utama dalam budidaya kentang dilahan miring adalah erosi. Upaya menekan erosi tanah diantaranya adalah tindakan konservasi mekanik dan penambahan bahan organik. Penelitian ini bertujuan untuk: (1) mengetahui pengaruh campuran pupuk organik hayati dan pupuk anorganik bersamaan dengan pola tanam sejajar kontur terhadap hasil kentang, (2) mengetahui pengaruh pola tanam sejajar kontur terhadap laju erosi lahan. Penelitian dilaksanakan di Kawasan Kaligua, Kecamatan Paguyangan, Brebes dan Laboratorium Ilmu Tanah Fakultas Pertanian, Universitas Jenderal Soedirman. Penelitian berlangsung selama 6 bulan dari bulan Oktober 2017-Maret 2018. Penelitian ini menggunakan Rancangan Acak Kelompok Lengkap (RAKL) dengan 3 faktor dan 3 kali ulangan, yaitu (1) arah guludan (L) dengan 3 taraf yaitu L1 (guludan miring 10% terhadap kontur), L2 (guludan miring 20% terhadap kontur) dan L3 (guludan tegak lurus terhadap kontur); (2) pupuk organik hayati (POH)(O) dengan 6 taraf yaitu O1 (Chicken manure 20 t/ha), O2 (POH 20 t/ha), O3 (POH 15 t/ha), O4 (POH 10 t/ha), O5 (POH 5 t/ha) dan O6 (POH 2,5 t/ha).; (3) pupuk anorganik (A) dengan 4 taraf yaitu A1 (ZA 1 ton/ha dan Phonska 250 kg/ha), A2 (dosis anjuran urea 300 kg/ha, SP-36 500 kg/ha, 300 kg KCl), A3 (1/2 dosis anjuran) dan A4 (1/4 dosis anjuran). POH dibuat dari Chicken Manure, Humat vulvat, Bio-P, Bio-T, dan N-HSL. Variabel yang diamati yaitu tinggi, jumlah daun, C organik, permeabilitas dan total produksi. Hasil penelitian ini menunjukkan bahwa perlakuan arah guludan miring 20% terhadap kontur memberikan pengaruh baik terhadap hasil kentang dibandingkan perlakuan lain dan mampu mengurangi laju erosi guludan tegak lurus terhadap kontur sebanyak 66,16%. |

| Abtrak (Bhs. Inggris) | The main problem in the cultivation of potatoes on the slopes is erosion. Efforts to reduce soil erosion include mechanical conservation measures and the addition of organic matter. This research aim was: (1) to know the effect of mixture of organic bio-fertilizer and inorganic fertilizer along with parallel planting pattern of contour to potato yield, and (2) to know the influence of parallel pattern of contour to land erosion rate. The research was carried out in the area of Kaligua, Paguyangan distric, Brebes and soil science laboratory of the Faculty of agriculture, Jenderal Soedirman University. The study lasted for 6 months from october until March 2017 2018. This study used a Randomized Complete Design Group (RAKL) with 3 factors and repeats three times, namely (1) the slopes with 3 levels i.e. L1 (sloping contours parallel dike wall 10%), L2 (sloping contours parallel dike wall 20%) and L3 (bunds perpendicular to contours); (2) organic bio-fertilizer (OBF) (O) with 6 levels i.e. O1 (Chicken Manure 20 tons/ha), O2 (OBF 20 tons/ha), O3 (OBF 15 tons/ha), O4 (OBF 10 tons/ha), O5 (OBF 5 tons/ha), and O6 (OBF 2.5 ton/ha ); (3) chemical fertilizers (A) with 4 levels i.e. A1 (1 ton/ha of ZA and 250 kg/ha of Phonska), A2 (the dose recommended by 300 kg/ha of urea, SP-36 500 kg/ha, 300 kg of KCl, A3 (1/2 dosage recommendations) and A4 (1/4 dosage recommendations).OBF made of Chicken Manure, Humat vulvat, Bio-P, Bio-T, and N-HSL. The observed variables i.e. height, number of leaves, permeability, organic C and total production. The results of this study indicate that sloping contours parallel dike wall 20% good effect on potato yield compared to other treatments and able to reduce erosion rate perpendicular to contour of 66,16%. |
