Ficus deltoidea var. deltoidea (Mas Cotek): A Promising Natural Antioxidant Agent

Ficus deltoidea var. deltoidea or locally known as ‘Mas cotek’ is a medicinal plant which have been used traditionally to treat toothache, wound, rheumatism, sores as well as to improve blood circulation. This present study was conducted to determine phytochemicals and antioxidant activity of the n-hexane, ethyl acetate and methanol extracts of the leaves of F. deltoidea var. deltoidea. Total phenolic content (TPC) was determined according to the FolinCiocalteau colorimetric method, while the antioxidant activity was carried out using 2,2diphenyl-1-picryhydrazyl (DPPH) radical scavenging assay. Phytochemical screening on the n-hexane extract revealed that this extract consisted of terpenes and steroids, while the ethyl acetate extract contained phenolics, saponins, tannins, terpenes and steroids. Flavonoids, phenolics, tannins and glycosides were found to be present in the methanol extract. Among the three extracts, the methanol extract gave the highest total phenolic content (323.74 mg GAE/g extract) and also exhibited the strongest DPPH radical scavenging activity (IC 50 129.27 µg/mL). This study suggested that the leaves of F. deltoidea var. deltoidea might be useful as a promising natural antioxidant for pharmaceutical purpose

A scenario CTF-based approach in cybersecurity education for secondary school students

Cybersecurity education topics require technical understanding. However, it is a challenging task for any teacher to introduce topics to students who have no technical background. Recently, the concept of gamification has been implemented as a tool to inculcate student’s interest using a variety of popular in-games techniques and applying them to educational modules. Extending from this notion, it was found that Capture the Flag (CTF) competition style is a successful way of introducing students to various technical concepts in the standard computer science curriculum. During the 2019 school holiday, a CTF for secondary school students was run at Universiti Tenaga Nasional (UNITEN) with the primary goal of introducing secondary school students to various cybersecurity topics and also to inculcate their interest in cybersecurity. The method that we used is different from other CTF or similar events, in which we use a scenario-based approach. We found that this method attracts participants in solving each challenge in a competitive environment
