Brokoli merupakan salah satu tanaman yang mengandung mengandung sulforaphane. Sulforaphane merupakan suatu senyawa antioksidan untuk mencegah penyakit kanker. Kandungan sulforaphane merupakan salah satu indikator kualitas sayuran. Sayuran dalam bentuk microgreens mempunyai kandungan nutrisi seperti folat, vitamin C, vitamin K, zat besi dan tinggi potasium (kalium), serta mengandung senyawa antioksidan seperti sulforaphane. Microgreens merupakan produk inovasi budidaya pertanian perkotaan. Microgreens dapat dibudidayakan di lahan sempit secara vertikultur (bertingkat) dan tidak membutuhkan radiasi matahari yang terlalu banyak. Microgereens merupakan sayuran yang dipanen pada usia yang sangat muda. Pemanenan dilakukan saat daun sejati pertama muncul dengan kotiledon sepenuhnya melebar. Microgreens tanaman brokoli ditanam di Green House Fakultas Pertanian UPN “Veteran” Jawa Timur pada bulan November-Desember 2018. Penelitian disusun menggunakan Rancangan Acak Lengkap (RAL) dengan dua faktorial yaitu media tanam yang terdiri dari 4 level dan pemberian air kelapa terdiri dari 2 level yang menghasilkan 8 kombinasi dan diulang sebanyak 3 kali. Status kandungan sulforaphane meningkat dengan adanya penambahan nutrisi dari air kelapa pada semua media tanam yang diujikan. Hasil terbaik diperoleh pada perlakuan media tanam cocopeat dengan pemberian air kelapa (M2S2).
Micro greens are vegetables harvested at a very early age, harvesting is done when cotyledon leaves and a pair of new leaves appear. Plant growth phases include germination, micro greens, baby greens, and mature in greens. This research aimed to determine the quality of microgreens broccoli (Brassica oleracea L.) that are water content, total chlorophyll, and dietary fiber due to the influence of planting media and coconut water nutrition. Broccoli microgreens are planted at the Green House of the Faculty of Agriculture, UPN “Veteran” East Java in November-December 2018. Analysis of water content using drying method(thermogravimetri), chlorophyll analysis using spectrophotometry method, and analysis of fiber content with Enzymatic-Gravimetric method. The data were analyzed using Completely Randomized Design (CRD) with the post hoc test LSD 5% and HSD 5% and correlation regression between parameters. The results of the study showed an increase in the quality of parameters and there was a close correlation between parameters. Correlation value of water content and total chlorophyll (r = 0.81) with a regression equation y = 1.907 × - 143.2, water content and fiber content (r = 0.84) with regression equation y = 2.628 × - 235.3 and total chlorophyll and fiber content (r = 0.88) with the regression equation y = 1.178 × - 32.05.
