Abstract

ABSTRAK Kebutuhan akan alternatif nutrisi hidroponik yang ramah lingkungan dan ekonomis semakin mendesak, terutama bagi petani pemula dan rumah tangga skala kecil. Larutan AB mix memang efektif namun dinilai kurang terjangkau dan tidak berkelanjutan untuk jangka panjang. Salah satu alternatif yang menjanjikan adalah eco enzyme, yakni larutan hasil fermentasi limbah organik yang kaya akan nutrisi dan dapat dibuat secara mandiri dengan proses sederhana dan biaya yang sangat rendah. Penelitian ini bertujuan untuk mengevaluasi efektivitas eco enzyme sebagai pengganti larutan AB mix dalam budidaya caisim (Brassica juncea L.) menggunakan sistem hidroponik wick. Penelitian ini menggunakan metode eksperimen kuantitatif dengan Rancangan Acak Lengkap (RAL) yang terdiri dari enam perlakuan: kontrol positif (AB mix), kontrol negatif (air bersih), serta larutan eco enzyme dengan konsentrasi 1,5%, 3%, dan 4,5%, masing-masing diulang sebanyak tiga kali. Parameter yang diamati meliputi tinggi tanaman, lebar daun, jumlah daun, dan berat basah tanaman selama masa pertumbuhan. Hasil penelitian menunjukkan bahwa perlakuan AB mix menghasilkan pertumbuhan tanaman terbaik, yaitu tinggi tanaman rata-rata ±33 cm, lebar daun ±12,33 cm, jumlah daun ±8 helai, dan berat basah ±100 gram. Perlakuan eco enzyme 4,5% memberikan hasil terbaik di antara konsentrasi lainnya, dengan tinggi tanaman ±20,75 cm dan berat basah ±48gram. Meskipun belum melebihi efektivitas AB mix secara statistik, eco enzyme menunjukkan kontribusi nyata terhadap pertumbuhan tanaman dan berpotensi besar dikembangkan sebagai nutrisi hidroponik alternatif yang ramah lingkungan, terjangkau, mudah dibuat, berkelanjutan, dan aplikatif dalam skala rumah tangga maupun pertanian urban modern. Kata Kunci: AB mix, Caisim, Eco enzyme, Hidroponik wick, Pertumbuhan tanaman. iii ABSTRACT The need for environmentally friendly and economical hydroponic nutrient alternatives is becoming increasingly urgent, especially for novice farmers and small-scale household growers. While AB mix solution is known to be effective, it is considered unaffordable and unsustainable for long-term use. One promising alternative is eco enzyme, a fermented liquid derived from organic household waste that contains essential nutrients and can be made independently using simple methods at a very low cost.This study aims to evaluate the effectiveness of eco enzyme as a substitute for AB mix solution in the cultivation of mustard greens (Brassica juncea L.) using a wick hydroponic system. The research employed a quantitative experimental method with a Completely Randomized Design (CRD) consisting of six treatments: a positive control (AB mix), a negative control (clean water), and eco enzyme solutions at concentrations of 1.5%, 3%, and 4.5%, each repeated three times. The observed parameters included plant height, leaf width, number of leaves, and fresh weight throughout the growth period. The results showed that the AB mix treatment produced the best plant growth, with an average height of ±33 cm, leaf width ±14.13 cm, number of leaves ±8, and fresh weight ±100 grams. The 4,5% eco enzyme treatment yielded the best results among the concentrations tested, with a plant height of ±20.75 cm and fresh weight of ±48grams. Although it has not statistically outperformed AB mix, eco enzyme demonstrated a clear positive effect on plant growth and has great potential to be developed as an alternative hydroponic nutrient that is eco-friendly, affordable, easy to produce, sustainable, and applicable in household and urban farming systems.
