Analisis Kandungan Flavonoid, Klorofil, dan Karotenoid Microgreen Kemangi ( Ocimum Bassilicum L.) pada Berbagai Media Tanam Inovasi Urban Gardening

Abstract

Microgreen crops are a solution to urban gardening innovation, the choice of yard vegetable production is easy to produce in urban areas where land is often a limiting factor for both farmers and vegetable consumers. One of the plant options that can be grown is microgreen basil. Microgreen basil can be consumed as fresh juice and as a vegetable salad that contains flavonoids, chlorophyll and carotenoids. The added value of basil microgreens can be increased through various growing media. The purpose of this study was to determine the effect of various planting media on increasing the content of flavonoids, chlorophyll and carotenoids of microgreen basil urban gardening innovation. This research was conducted in the community house yard, Taman Setiabudi Indah complex, Kel. Tj. Sari, Kec. Medan Selayang, Medan City in September - November 2023, using Non Factorial Randomized Group Design (RAK) with several treatments namely Topsoil (Control), Topsoil: Husk Charcoal (1:1), Topsoil: Cocopeat (1:1), Topsoil: Vermiculite (1:1), Topsoil: Cocopeat: Vermiculite (1:1:1). The parameters measured were plant height, plant fresh weight, flavonoids, chlorophyll and carotenoids. The results showed that the growing media had a significant effect on increasing plant height, plant fresh weight, chlorophyll A, chlorophyll B and total chlorophyll, carotenoid content but had no significant effect on flavonoid content in basil microgreens (Ocimum basillicum L.). In conclusion, Topsoil + Cocopeat + Vermiculite (1:1:1) planting media has a significant effect in increasing plant height, chlorophyll a, chlorophyll b, total chlorophyll and carotenoid content. Topsoil + Cocopeat (1:1) had a significant effect in increasing fresh weight. Total flavonoid content showed an increase in all growing media but was not significant in basil microgreens (Ocimum basillicum L.).
