Abstract

Penelitian ini dilakukan untuk mengetahui kebutuhan nitrogen pada tanaman sawi pakcoy ( Brassica rapa L.) yang dibudidayakan dengan sistem hidroponik Nutrient Film Technique (NFT) di Kebun Sayur Surabaya. Kegiatan berlangsung dari 28 Juli hingga 23 Agustus 2025 dan bersifat observatif-deskriptif melalui pengamatan langsung terhadap pertumbuhan serta kondisi fisiologis tanaman. Variabel yang diamati meliputi tinggi tanaman, jumlah daun, tingkat kehijauan daun menggunakan Leaf Color Chart (LCC), dan bobot segar saat panen. Hasil menunjukkan bahwa ketersediaan nitrogen berpengaruh nyata terhadap pertumbuhan vegetatif pakcoy. Tanaman dengan tingkat kehijauan daun LCC 4–5 tumbuh paling optimal, memiliki tinggi rata-rata 25,8 cm, jumlah daun 11–12 helai, serta bobot segar mencapai 175,7 gram. Sementara itu, tanaman dengan nilai LCC 2–3 menunjukkan pertumbuhan lebih lambat dan daun berwarna kekurangan akibat kekurangan nitrogen. Penggunaan LCC terbukti efektif sebagai metode sederhana dalam menilai kebutuhan nitrogen tanpa analisis laboratorium, sehingga dapat dijadikan acuan bagi pelaku budidaya hidroponik dalam pengelolaan nutrisi. Hasil penelitian membuktikan bahwa pengaturan nitrogen yang tepat menjadi kunci dalam meningkatkan pertumbuhan, produktivitas, dan kualitas sawi pakcoy pada sistem hidroponik yang efisien dan berkelanjutan.

Abstract

The growth of shallot plants using conventional soil methods is often constrained by the limited efficiency of water use and uneven nutrient availability. This study aims to analyze the effectiveness of an aquaponic system with various growing media (gravel, charcoal, cocopeat, and hydroton) compared to conventional soil cultivation. The experimental method was conducted by observing leaf length (cm) and the number of leaves over 15 days in each growing medium. The results showed that the aquaponic system significantly enhanced shallot growth compared to the soil method. Hydroton medium provided the best results, with leaf length reaching 28 cm and 7 leaves within 15 days, outperforming other media. Growth efficiency in hydroton reached 84.21% at the 5-day observation. The study concludes that the aquaponic system is more efficient in supporting shallot growth than the soil method, offering better water savings, more consistent nutrient availability, and supporting the concept of sustainable agriculture.
