Abstract

Natural resource management is one of the primary needs of all living things, both for consumption and supporting other activities. Batu City, East Java Province, is a tourist area and a water catchment area that has the potential to be a source of ground water. However, the development of infrastructure as a espoused of tourist areas need serious undermining of the sustainability of the land water source. In 2001 the environmental carrying capacity ratio was 1.75 with a conditional safe status. In 2011 and 2015 the status of environmental carrying capacity has been exceeded with a ratio of 0.85 and 0.62. In 2017 there is a conditional safe status with an environmental carrying capacity ratio of 1.24.Keywords: Demand Water Resources, Ratio of carrying capacity, Supply water resources,

Abstract

Tujuan penelitian untuk mengetahui pengaruh pemberian kotoran sapi terhadap sifat kimia tanah, pencucian nitrat dan pertumbuhan tanaman jagung manis. Aplikasi pupuk kandang sapi diduga dapat memperbaiki sifat kimia tanah, mengurangi pencucian nitrat dan memperbaiki pertumbuhan jagung manis. Penelitian di rumah kaca, menggunakan Rancangan Acak Lengkap (RAL) sederhana. Perlakuan dosis pupuk nitrogen : 0, 100, 200, 300, 400, 500 kgN /ha. Perlakuan pupuk kandang sapi: tanpa pupuk kandang, pupuk kandnag dosis 39.72 ton/ha (setara 76.39 g/pot). Hasil penelitian menunjukkan bahwa pemberian pupuk nitrogen yang dikombinasikan dengan pupuk kandang sapi memperbaiki sifat kimia tanah,  menurunkan pencucian nitrat rata-rata sebesar 13.68 % dibandingkan kontrol, dan  memperbaiki pertumbuhan tanaman jagung manis. Kombinasi perlakuan K1N2 ( Nitrogen 200 kg/ha + BO 76,39 g/pot (setara 39.72 ton/ha) menghasilkan serapan N tanaman paling tinggi (383.76 mg/tanaman) dan efisiensi penggunaan nitrogen sebesar 69.00 kg/ha dibandingkan perlakuan lainnya. Kata kunci: pupuk kandang sapi, nitrogen, jagung manis
