Abstract

This study aims to evaluate the growth and vitamin C content of red amaranth microgreens (Amaranthus tricolor) under various nutrient concentrations and growing media. The experimental design used in this study was a Randomized Complete Block Design arranged factorially 5 x 3 (15 treatments) with 3 repetitions. The first factor was the concentration of hydroponic nutrients at levels of 0 ppm, 100 ppm, 200 ppm, 300 ppm, and 400 ppm. The second factor was the combination of growing media, namely sand + sawdust, sand + rice husk charcoal, and sand + cocopeat, with a 1:1 ratio for each combination. Data obtained from the observed variables were analyzed using variance analysis and further tested with an LSD test at a 5% significance level. The observed parameters included germination rate (%), plant height (cm), number of leaves, leaf color, root length (cm), number of roots, plant weight (mg), and vitamin C content. The results showed that the use of sand + rice husk charcoal as a growing medium was very suitable for the germination of red spinach microgreens. However, for leaf color and root length, the use of sand + cocopeat was better. The sand + cocopeat medium combined with nutrient concentrations of 300 ppm and 400 ppm produced the best plant height and sample weight compared to other treatments. Furthermore, the sand + sawdust medium was very effective in producing the number of roots and the vitamin C content of red spinach microgreens.

Abstract

Salah satu inovasi pertanian perkotaan yaitu budidaya microgreen. Microgreen merupakan tanaman dipanen berumur muda yang dapat memenuhi ketahanan pangan dalam skala rumah tangga dan memiliki kandungan antioksidan. Tujuan dari penelitian ini adalah untuk menganalisis dan mengkaji benih kacang tunggak dengaan perlakuan jarak grow light dan fitohormon ekstrak air bawang merah dan air kelapa terhadap kandungan antioksidan, susut bobot, pajang akar dan warna daun. Penelitian ini menggunakan rancangan acak kelompok (split plot) yang terdiri dari 2 faktor. Faktor pertama adalah jarak lampu terdiri atas 20 cm, 40 cm, dan 60 cm, sedangkan faktor kedua adalah jenis dan konsentrasi fitohormon terdiri atas akuades, akuades 50% + air kelapa 50%, akuades 50% + ekstrak bawang merah 50%, dan akuades 50% + air kelapa 25% + ekstrak bawang merah 25%. Jarak lampu grow light 40 cm menghasilkan hasil terbaik pada parameter susut bobot sebesar 1,04 g, sedangkan penggunaan perlakuan akuades 50% + ekstrak bawang merah 50% menghasilkan pengaruh yang baik terhadap parameter kandungan antioksidan dan susut bobot mencapai 77,62 µg mL-1 dan 0,93 g. Kombinasi perlakuan akuades 50% + air kelapa 50% pada jarak grow light 20 cm menghasilkan warna daun terbaik, hijau kekuningan tua.
