Abstract

ABSTRAK Penelitian ini bertujuan untuk menganalisis aliran permukaan yaitu debit dan kecepatan aliran permukaan pada areal pertanaman wortel dengan tindakan teknik konservasi tanah dan air yaitu guludan tradisional dan teras guludan dengan penutupan mulsa plastik. Lokasi penelitian terletak di Kelurahan Rurukan, Kecamatan Tomohon Timur. Metode yang digunakan adalah metode petak kecil dengan dua perlakuan teknik konservasi tanah dan air yaitu guludan tradisional dan teras guludan dengan penutupan mulsa plastik. Hasil penelitian menunjukkan bahwa aliran permukaan pada areal pertanaman wortel dengan teknik konservasi tanah dan air dengan penutupan mulsa plastik lebih tinggi dibandingkan dengan tanpa penutupan mulsa plastik yaitu guludan tradisional. Volume aliran permukaan lebih tinggi 130% dan koefisien aliran permukaan lebih tinggi 100%. kata kunci: aliran permukaan, Rurukan, konservasi tanah dan air

Abstract

ABSTRACT The purpose of this study was to determine the effect of compost on land mined gold and knowing which one is the best type of compost to the early growth of the plant jackfruit. This research used Completely Randomized Design (CRD) factorial with 2 faktoral namely Factor A: types of compost with three levels while the B factors and three levels of fertilization and repeated 3 times so have 27 pot experiment. The results composting on mined land can improve soil chemical properties in this case the addition of the nutrients N, P, K and C-organic. Nutrient content of compost can be seen that the highest N content contained in compostable materials made of peanuts is 0.8%. While the highest available P in compost bins gamal is 16.79 ppm, the highest available K in compost market is 55.3 ppm and C-gamal organic compost is the highest at 9.11%. Jackfruit plant growth height and number of leaves both the best in the mined soil compost bins given market.
