Abstract
Jumlah penduduk kota Surabaya dari tahun 2014 sampai 2015 mengalami peningkatan sebesar 4,45%. Lahan pertanian di Kota Surabaya mengalami penyusutan lahan sebesar 75 hektar setiap tahunnya. Peningkatan jumlah penduduk kota Surabaya berbanding terbalik dengan ketersediaan lahan pertanian. Solusinya adalah menerapkan konsep baru urban farming. Hasil optimasi eksisting menghasilkan intensitas tanam sebesar 289% dengan pola tanam padi-palawija-palawija, sedangkan optimasi rencana menghasilkan intensitas tanam sebesar 240% dengan pola tanam palawija-palawija (hidroponik tingkat atas), intensitas tanam sebesar 311% dengan pola tanam palawija-palawija-palawija (hidroponik tingkat bawah), dan budidaya ikan lele sistem bioflok. Kebutuhan air rencana sebesar 3,63x106 liter sedangkan ketersediaan tampungan air total sebesar 3,75x106 liter. Nilai benefit cost ratio (BCR) eksisting dan rencana masing-masing sebesar 0,09 dan 1,43. Nilai net present value (NPV) eksisting dan rencana masing-masing sebesar Rp.-115.719.410,06 dan Rp. 2.956.052.297,26. Nilai payback period (PP) eksisting dan rencana membutuhakn 12,39 tahun dan 1,7 tahun.
==================================================================================================================
The population of Surabaya city from 2014 to 2015 increased by 4.45%. Agricultural land in the Surabaya city experiences 75 hectares of land every year. The increase in the population of the city of Surabaya is inversely proportional to the availability of agricultural land. The solution is to apply a new concept of urban farming. The optimization of the existing resulted in cropping intensity of 289% with rice-vegetabele-vegetabele cropping patterns, while optimization of the plan resulted in cropping intensity of 240% with vegetabele-vegetabele cropping patterns (top level hydroponics), 311% with vegetabele-vegetabele-vegetabele cropping patterns (low level hydroponics), and catfish farming by biofloc’s system. The water demand is 3.63x106 liters while the water supply is 3.75x106 liters. BCR of existing and plans are 0.09 and 1.43. NPV of existing and plans are -115,719,410.06 IDR and 2,956,052,297.26. IDR. PP of existing and plans require 12.39 years and 1.7 years.
