Abstract

Red lettuce (Lactuca sativa var. Crispa) is a leaf vegetable plant that has curly or wavy leaf shapes and reddish green color. This plant is favored by urban communities in the city because it has good nutritional value, is easy to grow, and is aesthetically pleasing. The limited space owned by the grower is the main obstacle in the cultivation of red lettuce in the city so that vertical or vertical cultivation techniques are needed. The vertical technique used is Wiremesh Tower Garden (WTG) verticulture. The aim of the study was to compare the effectiveness of the growth and production of red lettuce in WTG with conventional cultivation in the field. The environmental design used was a Randomized Block Design (RAK) which consisted of two factors, namely cultivation techniques as the first factor consisting of WTG and conventional/open land. While the spacing is the second factor which consists of 10x12 cm and 20x24 cm. The results of this study indicate that the wiremesh tower garden planting technique provides more efficient results in the cultivation of red lettuce. Spacing of 10x12 cm in the WTG planting technique gave good results for the variables of leaf width, number of leaves, crown fresh weight, root wet weight, production weight, and vitamin C content. The use of WTG planting technique with a spacing of 10x12 cm gave effective results in red lettuce cultivation, because the results of growth and production were not significantly different from planting techniques on land at the same spacing

Abstract

Salah satu isu dalam pertanian perkotaan adalah pengelolaan limbah. Banyaknya limbah di perkotaan belum banyak dikelola secara baik. Salah satu limbah yang dapat dikelola dan dimanfaatkan adalah limbah perikanan sebagai bahan baku pupuk organik. Tujuan dari penelitian ini mengetahui respon pertumbuhan dan hasil panen pakcoy terhadap pemberian pupuk organik cair limbah perikanan. Metode penelitian menggunakan RAKL secara faktorial diulang empat kali. Faktor pertama adalah dosis pupuk urea dengan lima taraf (0, 25%, 50%, 75%, dan 100% dari dosis rekomendasi 250 kg ha-1), dan Faktor kedua adalah konsentrasi pupuk cair organik dari limbah perikanan dengan lima taraf (0, 2, 4, 6, dan 8 ml L-1). Terdapat 25 kombinasi perlakuan dengan 6 tanaman per satuan percobaan, sehingga ada 600 sampel tanaman yang diteliti. Penelitian ini dilakasanakan di Kebun Bergizi, dan Laboratorium Agroekoteknologi, Universitas Trilogi, pada bulan September sampai Oktober 2018. Hasil penelitian menunjukkan kombinasi perlakuan 50% pupuk urea dan 2 ml L-1 pupuk cair organik memberikan hasil yang lebih baik dibandingkan dengan kontrol perlakuan lainnya pada indikator pertumbuhan. Pada peubah jumlah daun layak konsumsi dan berat segar tanaman pada kombinasi perlakuan 50% pupuk urea dan 2 ml L-1 yaitu 19.11 helai, dan 220.77 g lebih berat dari perlakuan 100% dosis urea yang digunakan.
