Mango is a significant global fruit crop, producing over 1,000 million tonnes annually. However, postharvest losses due to pathogenic fungal infections are considerable, exacerbated by the continuous use of synthetic fungicides, which pose risks of fungal resistance and environmental harm. This study assessed the effectiveness of Origanum vulgare-b...

Xanthine oxidase is a crucial enzyme in the regulation of uric acid, with elevated levels leading to gout and hyperuricemia. To combat these conditions, a synergistic approach using antioxidants and xanthine oxidase inhibitors presents a promising treatment strategy. Given the side effects of synthetic inhibitors, this study explores the natural xa...

An infection by pathogenic fungi is one of the major problem in post-harvest stage of mangoes. Therefore, the extraction of essential oil from Melaleuca alternifolia is being tested as a natural fungicide for controlling fungus infections of selected mangoes locally known as susu mango. The extraction was performed using Solvent-Free Microwave Assi...

Water quality is an important parameter for the health and growth of aquatic species in aquaculture farming system. The threshold values of the water main parameters should be monitored continuously. Contaminated aquaculture water will affect the health, growth and ability of animals to survive. In addition, it will also affect the harvesting yield...

Antioxidant is a basic requirement for maintaining good health and antidiabetic is very important for maintaining blood glucose level of diabetes mellitus patients. In this research, natural compounds were extracted from Curcuma xanthorrhiza (Javanese turmeric). The compounds were extracted using ultrasonic assisted extraction (UAE) for in-vitro an...

This work evaluates the fungicidal effect of essential oil from Coleus aromaticus (C. aromaticus) by solvent-free microwave-assisted extraction with a yield of 0.54%. Fourier-transform infrared spectroscopy was utilised to identify the functional groups, which were O–H, C–O, C–H, and C=C. Gas chromatography–mass spectrometry analysis was performed...

Antioxidant is a basic requirement for maintaining good health. In this research, natural antioxidant was extracted from C. aromaticus by using different types of synthesized deep eutectic solvents (DES). The extracts were analysed using total phenolic content assay and DPPH radical scavenging assay. Finally, HPLC and FTIR methods were employed to...

Mangifera indica var Harumanis is one of the exotic mango cultivated in Perlis, Malaysia. It economic importance increased in recent years due to the popularity attributed to it excellent taste, sweet and aromatic fragrance. Supply of Harumanis cannot meet market demand, mainly due to the difficulty of raising the crops and the short and uncertain...

Radio waves Frequency (RF) propagating in vegetation environments usually facing much higher path loss than in environments those without vegetation. Therefore, well known of the propagation path loss through the vegetation area is critical for communication and sensing of Wireless sensor network (WSN) in such environments. Furthermore, the well kn...

Dye-sensitized solar cell (DSSC) was fabricated with seven natural dye extract; Rosella, Bawang Sabrang, Cherry Barbados, Mulberry, Ardisia, Oxalis Triangularis, and Harum Manis mango. The DSSCs are fabricated and characterized to obtain the performances of each dye under variation of extracting temperature. The dyes are extracted into water and et...

Application of plant extracts as alternative to commercial insecticides provide an eco friendly non hazardous control method. The gold dust beetle (Hypomeces squamosus L.) is among the insects that produce cuts, holes, or leaf falls, as they feed on mango leaves. A field trial (RBD, 4 replicates) was conducted to evaluate the effect of ethanol extr...
