Abstract

The purpose of this study to determine the effect of POC and AB Mix on the growth and yield of pakchoy. This research was conducted in February and March 2016. Starting from seeding to harvest. Research located in the village Sepakat, District Tenggarong Seberang, Kutai Kartanegara. The study used a randomized block design (RAK) with factorial analysis 2 with repetition as much as (3). The treatment is a liquid organic fertilizer (P), which consists of 4 levels, namely p0 (control), p1 (5 ml POC L-1 water), p2 (10 ml POC L-1 water), p3 (15 ml POC L-1 water) and provision of AB Mix (N), which consists of 4 levels, namely n0 (control), n1 (AB Mix 600 ppm), n2 (AB Mix 1,200 ppm), n3 (AB Mix 1,800 ppm). The results showed that treatment of liquid organic fertilizer results showed no significant effect on all parameters but treatment provision Mix AB showed a highly significant effect on all parameters with results of the highest weight at treatment plants n3 (AB Mix 1,800 ppm).Keyword : Hydroponik, pakchoy, AB mix

Abstract

The leaf of five selected medicinal plants namely Mangifera indica, Muntingia calabura, Phaleria macrocarpa, Morinda citrifolia and Garcinia mangostana were investigated to determine their therapeutic potential to inhibit key enzymes in carbohydrate metabolism, which has relevance to the management of hyperglycemia and type 2 diabetes. The free radical scavenging activity was also assessed using DPPH assay. The studied plants exhibited varied free radical scavenging and α-glucosidase inhibition activities. The most potent antioxidant activity was demonstrated by M. indica extracted using 50 % ethanol with an IC50 value of 15.79±1.79 μg/mL. Both 50 and 100 % ethanol extracts of G. mangostana and 50% ethanol extract of M. calabura also showed strong antioxidant activity with IC50 values of 21.77 ± 6.97, 25.99± 1.37 and 36.90 ± 6.89 μg/mL, respectively. Of all the plants examined for α-glucosidase inhibition activity, M. calabura extracted with 50 % ethanol exhibited higher activity with IC50 value of 0.48±0.12 μg/mL. The results obtained in this study showed that M. indica leaves as the most potent antioxidant and could be suggested as a potential natural source of antioxidant compound. Meanwhile, M. calabura leaves have good potential for the management of hyperglycemia, diabetes and the related condition of oxidative stress.
