The rapid increase in population results in a transformation of agricultural land into residential areas. Household yards emerge as an option to sustain food security. Microgreens, vegetables harvested within the age range of 7-14 days after seeding, are the focal point of this study. The research aims to assess the impact of LED light colours and the concentration of liquid organic fertilizer (LOF) from moringa leaves on the growth and yield of pakchoi microgreens. The study is conducted at Jalan Sam Ratulangi No.39, Kota Kediri, East Java, from May 2022 to June 2022. A Randomized Complete Block Design (RCBD) Split Plot method is employed with two treatment factors replicated three times. The main treatment factor involves four LED light colours, and the research findings indicate a significant interaction between LED colours and the concentration of moringa leaf LOF concerning leaf quantity at 14 HST and leaf area. The best combinations were treatments L1S3 (blue light irradiation and 45 ml/litre concentration of moringa leaf LOF), L4S1 (yellow light irradiation and 15 ml/litre concentration of moringa leaf LOF), and L2S1 (red light irradiation and 15 ml/litre concentration of moringa leaf LOF). The application of moringa leaf LOF at 15 ml/litre separately also significantly affected the seed germination capability of pakchoi at 14 DAP. Additionally, LED irradiation showed significant differences in leaf quantity at 7 DAP and plant height at 7 HST.
Dampak dari pertumbuhan penduduk yang cepat menyebabkan perubahan fungsi lahan pertanian di area pemukiman. Sebagai upaya untuk memastikan ketahanan pangan, halaman rumah menjadi opsi yang dipilih. Penelitian ini berfokus pada microgreens, yaitu tanaman sayuran yang dipanen dalam rentang usia 7 hingga 14 hari setelah penanaman. Tujuan dari penelitian ini adalah untuk mengevaluasi pengaruh warna lampu LED dan konsentrasi larutan POC daun kelor terhadap pertumbuhan dan hasil microgreens pakcoy. Lokasi penelitian berada di Jalan Sam Ratulangi No. 39, Kota Kediri, Provinsi Jawa Timur, pada bulan Mei hingga Juni 2022. Metode yang digunakan adalah rancangan acak lengkap (RAL) split-plot dengan dua faktor perlakuan dan tiga ulangan. Faktor utama melibatkan empat warna LED, dan terdapat interaksi signifikan antara warna LED dan konsentrasi POC larutan daun kelor terhadap jumlah dan luas daun pada 14 HST. Kombinasi optimal melibatkan lampu biru dengan konsentrasi POC daun kelor sebesar 45ml/liter, lampu kuning dengan konsentrasi 15ml/liter, dan lampu merah dengan konsentrasi 15ml/liter. Perlakuan individu POC daun kelor sebanyak 15 ml/liter juga berpengaruh pada perkecambahan biji bok choy pada 14 HST. Di samping itu, pencahayaan LED menunjukkan perbedaan yang signifikan pada jumlah daun pada usia 7 HST dan tinggi tanaman pada usia 7 HST secara independen.
