Abstrak Penelitian ini bertujuan untuk menganalisis pertumbuhan dan produksi tanaman kemangi (Ocimum basilicum) yang menggunakan pupuk organik cair air cucian beras diperkaya MSG sebagai nutrisi hidroponik wick system. Penelitian ini dilaksanakan dari Bulan April hingga bulan Agustus 2024 di Green House Nino Park Universitas Syiah Kuala. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan dan 4 kali ulangan. Perlakuan terdiri dari POC 20 mL/2000 mL (P1), POC 40 mL/2000 mL (P2), 60 mL/2000 mL (P3), 80 mL/2000 mL(P4) dan perlakuan positif (P+) yaitu AB MIX 20mL/2000 mL. Parameter pertumbuhan yang diukur adalah jumlah daun, tinggi tanaman, panjang daun, lebar daun, berat segar serta pengamatan karakteristik fisik POC. Hasil penelitian menunjukkan bahwa pemberian pupuk organik cair air cucian beras yang diperkaya MSG memberikan pengaruh yang nyata terhadap pertumbuhan jumlah daun, tinggi tanaman, panjang daun, lebar daun, dan berat segar tanaman. Perlakuan P2 (40 mL+2000 mL) menghasilkan rataan jumlah daun, tinggi tanaman, panjang daun, lebar daun, dan berat segar tertinggi pada seluruh taraf perlakuan POC. Pengamatan karakteristik fisik POC yang dilihat berdasarkan warna, aroma dan pH pada penelitian ini sudah sesuai dan dapat digunakan. Warna POC setelah fermentasi dan penambahan MSG pada penelitian ini adalah kuning kecokelatan, aroma asam segar (khas tape), dan pH 5,5.

This research aims to analyze growth and production of basil plants (Ocimum basilicum) using liquid organic fertilizer from rice washing water enriched with MSG as nutrient in wick system hydroponic. This research had been carried out from April to August 2024 at Green House Nino Park, Syiah Kuala University. This study used a completely randomized (CRD) with 5 treatments and 4 replications. The treatment consisted of AB mix 20 mL/2000 (P+), and four variations of POC solution, namely POC 20 mL/2000 mL (P1), 40 mL/2000 mL (P2), 60 mL/2000 mL (P3), 80 mL/2000 mL (P4). The parameters measured were leaf count, plant height, leaf lenght, leaf width, plant fresh weight and physical characteristics of POC. The result showed that the application of liquid organic fertilizer made of rice washing water enriched with MSG has a significant effect on the growth of leaf count, plant height, leaf length, leaf width and fresh weight of the plant. Treatment P2 (40 mL + 2000 mL) resulted in the highest average values for the number of leaves, plant height, leaf length, leaf width, and fresh weight among all levels of POC treatment. The POC's color, aroma, and pH characteristics assessed in this research were suitable and could be recommended for use. The color of the POC obtained after fermentation and the addition of MSG in this study is yellow-brown, with a fresh, sour aroma characteristic of fermented cassava, and a pH of 5.5.
