Non enzymatic and enzymatic antioxidant activities in aqueous extract of different Ficus deltoidea accessions
Ficus deltoidea was used in this study due to its reputation in reducing risk of cancer, diabetes and
heart diseases. In this study 13 accessions of F. deltoidea were selected and they were divided into two groups, generally named as, female and male plants based on leaf sizes and the spots present. The signature of F. deltoidea is that this plant has black spots representing the female leaf while red spots for the male leaf. For non enzymatic antioxidants, several methods were used, they were 2,2-diphenyl-1-picrylhydrazil (DPPH) free radical scavenging assay and ferric reducing antioxidant power (FRAP) assay for total antioxidant content. In addition, total polyphenol, flavonoid, phenolic acid and vitamin C content were also analyzed. Enzymatic antioxidants of F. deltoidea leaf extracts were assayed; ascorbate oxidase, peroxidase, catalase and ascorbate peroxidase. For DPPH assay, F1 has 99.87% of inhibition while the lowest is in M10 (32.86 %). F13 has the highest total percentage of antioxidant for
FRAP method and the lowest is in M4. Total polyphenol content showed F13 has the highest (1.30 mg/g FW) and M10 the lowest (0.49 mg/g FW). Similar trend was observed for total phenolic acid and flavonoid content. For both assays, F1 has the highest content while M10 is the lowest. For total vitamin C content, F8 and F7 have the highest and lowest content with 6.78 and 0.61 mg/g FW, respectively.
Ascorbate oxidase, peroxidase, catalase and ascorbate peroxidase were calculated using respective coefficient extinction and expressed as mg/g FW protein content. This study suggested that the extracts of the female leaves are better than male leaves in most of the assays. This is the first documented report on the antioxidants of F. deltoidea
Antioxidative properties of leaf extracts of a popular Malaysian herb, Labisia pumila.
A study was undertaken to examine the presence of antioxidative activities of two varieties of Labisia pumila; L. pumila var. Alata and L. pumila var. Pumila using DPPH, FRAP and β-carotene bleaching methods. In addition, ascorbic acid, β-carotene, anthocyanin, total flavonoid and total phenolic content were also analyzed. In eight methods studied, six of them showed high activities of antioxidant in L. pumila var. Alata compared to that of L. pumila var. Pumila. The results obtained showed that L. pumila var. Alata contained higher antioxidative activities in all three methods applied compared to var. Pumila. In DPPH, FRAP and β-carotene bleaching methods, L. pumila var. Alata had high antioxidant activities with 299.84 µM trolox/g db, 164.16 µM trolox/g db and 89.22%,respectively. The same pattern of antioxidant activities also can be observed in ascorbic acid, β-carotene and anthocyanin in L. pumila var. Alata compared to var. Pumila with 0.022, 3.175 and 0.328 mg/g FW, respectively. L. pumila var. Pumila had higher total flavonoid content than L. pumila var. Alata with 1.281 mg/g FW. For total phenolic content, no significant different was observed because the amount of total phenolic content ranging from 2.53 to 2.55 mg/g FW. There is a positive correlation between antioxidant capacities and individual antioxidative compounds in the following order β-carotene>flavonoid>vitamin C>total anthocyanins >phenolics

From digital learning to artificial intelligence: Enhancing autonomy among students of Islamic education
The digitalization of education has significantly broadened access to diverse learning resources, including Artificial Intelligence (AI)-powered tools, thereby offering new avenues for students to cultivate greater autonomy in their learning. This study investigates the level of learner autonomy, the contributing factors, and the potential of AI in supporting autonomous learning among undergraduate students of Islamic Religious Education in the digital learning era. Employing an explanatory mixed-methods design, the research integrates quantitative and qualitative approaches. Quantitative data were collected through a structured questionnaire distributed to 103 students and analyzed using descriptive statistics, while qualitative insights were obtained through semi-structured interviews with four participants. Quantitative findings reveal a high overall level of learner autonomy (mean = 3.66), particularly in students’ ability to access learning materials independently (mean = 4.07), utilize digital resources effectively (mean = 4.02), and select appropriate learning strategies (mean = 3.91). However, limitations persist in students’ reliance on lecturers for digital resource utilization (mean = 2.92) and moderate digital proficiency (mean = 3.56). Key contributing factors include the accessibility of digital learning resources (mean = 3.96) and lecturer guidance (mean = 3.76). Qualitative results highlight the promising potential of AI tools, such as chatbots, intelligent tutoring systems, and adaptive learning platforms, in providing personalized support, instant feedback, and motivation for independent learning. These findings underscore the importance of integrating AI technologies and tailored instructional strategies to foster learner autonomy. The study offers empirical evidence to inform curriculum development and policy initiatives that strengthen self-directed learning in Islamic higher education

Oil Palm Frond Juice as Future Fermentation Substrate: A Feasibility Study
Oil palm frond (OPF) juice is a potential industrial fermentation substrate as it has high sugars content and the OPF are readily available daily. However, maximum sugars yield and storage stability of the OPF juice are yet to be determined. This study was conducted to determine the effect of physical pretreatment and storage duration of OPF petiole on sugars yield. Storage stability of OPF juice at different storing conditions was also investigated. It was found that OPF petiole squeezed by hydraulic pressing machine gave the highest sugars recovery at almost 40 g/kg, accounting for a recovery yield of 88%. Storage of OPF petiole up to 72 hrs prior to squeezing reduced the free sugars by 11 g/kg. Concentrated OPF juice with 95% water removal had the best storage stability at both 4 and , when it was stored for 10 days. Moreover, concentrated OPF syrup prepared by thermal processing did not give any Maillard effect on microbial growth. Based on our results, OPF juice meets all the criteria as a good fermentation substrate as it is renewable, consistently available, and easy to be obtained, it does not inhibit microbial growth and product formation, and it contains no impurities
