Abstract

Urban farming is an adaptive strategy to address land limitations and food security in densely populated urban areas. This study aims to identify and classify yard land potential for urban farming development in Sario Subdistrict, Manado City. A spatial analysis method was employed using overlay techniques on datasets including residential buildings, land parcels, land use, and administrative boundaries, with additional location verification by Google Earth. The results identified 3,019 land units with a total potential area of 47,43 hectares, categorized into three levels of potential: high potential (>50 m²) around 93,53%, moderate potential (10–50 m²) around 6,37%, and marginal potential (<10 m²) around 0,11%. These things indicate substantial opportunities for household-based agriculture. Recommended agricultural systems vary based on available yard area, including horizontal gardening, vertical farming, and modular hydroponics. These findings highlight the need for integrated policy support and community empowerment to promote adaptive and sustainable urban farming in high-density residential areas like Sario Subdistrict.

Abstrak

Pertanian perkotaan menjadi strategi adaptif dalam menghadapi keterbatasan lahan dan ketahanan pangan di wilayah perkotaan padat penduduk. Penelitian ini bertujuan untuk mengidentifikasi dan mengklasifikasikan potensi lahan pekarangan untuk pengembangan pertanian perkotaan di Kecamatan Sario, Kota Manado. Metode yang digunakan adalah analisis spasial berbasis overlay data bangunan rumah hunian, bidang tanah, penggunaan lahan, dan batas administrasi, dengan validasi visual melalui Google Earth. Dari hasil analisis, ditemukan sebanyak 3.019 unit pekarangan rumah hunian dengan luas total 47,43 hektar yang diklasifikasikan menjadi tiga kategori potensi: sangat berpotensi (>50 m²) sekitar 93,53%, cukup berpotensi (10–50 m²) sekitar 6,37%, dan berpotensi marjinal (<10 m²) sekitar 0,11%. Hal ini menunjukkan peluang besar pengembangan pertanian berbasis rumah tangga. Strategi sistem pertanian yang direkomendasikan disesuaikan dengan luasan pekarangan, meliputi pertanian horizontal, vertikultur, dan hidroponik modular. Temuan ini menegaskan pentingnya dukungan kebijakan yang terintegrasi serta pemberdayaan masyarakat dalam mendorong pertanian perkotaan yang adaptif dan berkelanjutan di kawasan permukiman padat seperti Kecamatan Sario.

Kata Kunci: pertanian perkotaan, pekarangan, analisis spasial
