Utilization of selenium in baglog waste to increase antioxidant and storability of broccoli

Abstract

Baglog waste contains cellulose, which can absorb selenium. Selenium can increase antioxidants and vegetable storability. This study aims to determine the selenium content of baglog waste in increasing antioxidants and broccoli storability. The study was conducted from May to July 2019 in Cipadung Village, Cibiru District, Bandung using the Completely Randomized Design (CRD) consisted of 5 treatments and 5 replications. The treatment was media A = 100% baglog waste, B = baglog waste mixture 25%: 75% rice husk charcoal, C = Baglog waste mixture 50%: 50% rice husk charcoal, D = Baglog waste mixture 75%: 25% rice husk charcoal, E = 100% rice husk charcoal (control). The results showed that the combination of 75% baglog waste media with 25% rice husk charcoal was able to increase antioxidants by IC50 28.34 ppm and storability for four days at room temperature. 75% baglog waste with 25% husk charcoal can be used as a medium for supplying selenium to get good antioxidants and storability of broccoli.
