PublicationDemographic disparities in 5G technology adoption among paddy farmers in Kedah: a comprehensive study( 2024-03)This research aims to investigate the adoption of 5G technology within the agricultural sector, specifically among rice farmers in Kedah, Malaysia, and understand the demographic disparities in 5G adoption. It also addresses the challenge of equitable 5G technology adoption and explores how demographic factors such as gender, age, ethnicity, and income levels influence adoption patterns. A mixed-methods approach, comprising surveys, interviews, and field observations, is employed to collect data from a diverse sample of farmers. The study utilizes theoretical frameworks related to automation, productivity, and connectivity to analyze the impact of 5G technology on agricultural practices. Only descriptive analysis of demographic characteristics will be reported after the survey is conducted using a questionnaire through the What'sApp application. The research reveals significant gender imbalances in adoption rates, with implications for equitable access to technological advancements. It also highlights the influence of age and income on adoption patterns. The study underscores the importance of tailored strategies to ensure the adoption of inclusive 5G technology in the agricultural sector

PublicationPerformance of Chlorella vulgarisin Phycoremediation of livestock effluent( 2024-03)Livestock effluent is known to contain significantly higher concentrations of organic matter and challenging-to-degrade organic compounds compared to urban wastewater. This makes the effluent treatment challenging and adversely affects nearby aquatic environments if improperly treated. Phycoremediation uses microalgae in water and wastewater treatment. This research aim was to evaluate pollutant removal efficiencies, including chemical oxygen demand (COD), total suspended solids (TSS), nitrate (NO₃-N), turbidity, and phosphate (P), using microalgae Chlorella vulgaris (C. vulgaris) cultivation systems for livestock effluent treatment. The biomass weight of C. vulgaris in the cultivation systems was also observed. In this study, C. vulgaris was cultivated in closed cultivation systems in 5 L water bottles with different dilutions (100%, 75%, 50%, and 25%). The water effluent was compared to permissible values using the National Water Quality Standard (NWQS) class II for recreational water use. TSS was significantly removed by 61.97%, while COD and P were removed by 39.1% and 36.4%, respectively. The biomass growth was observed through the dry weight of the C.vulgaris. Therefore, the removal of nutrients from cattle farm effluent by phytoremediation using C. vulgaris demonstrates potential for treatment efficacy.

PublicationHot air drying of Brazilian spinach leaves( 2024-03)Brazilian spinach is one of the best leafy vegetables with tons of nutrients and has a range of health benefits. Its quality also determines the acceptance of customers to buy and consume it. The common method to extend the shelf life of the spinach is through drying treatment and preserving the color and texture quality of the leaves. Therefore, this study aimed to determine the drying characteristics of Brazilian spinach and investigate the effect of drying temperature on the color and texture quality of Brazilian spinach. Brazilian spinach leaves were dried using a hot air dryer under different temperatures (30, 50, 70 and 90C). Results showed that the drying rate increased when temperature increased. It was found that the Midili model gave the best fitting to the experimental moisture ratio for a specific drying treatment. Drying the Brazilian spinach leaves at 50C was the best condition for preserving their color and texture properties.

PublicationPhytochemical screening and insecticidal activity of Cyperus iria, Fimbristylis globulosa and Fimbristylis miliacea toward Sitophilus oryzae L.( 2024-03)The rice weevil, Sitophilus oryzae is one of the famous insect pests that cause the low quality of the rice seeds. Fimbristylis miliacea, Fimbristylis globulosa and Cyperus iria are sedge weeds that are common near swampy areas. These weeds are classified as potential due to their high nutritional value and chemical compound content. Natural compounds from plant extracts prove the potential to develop as a new natural bio-insecticide in terms of agriculture usage. Cyperus iria, Fimbristylis globulosa and Fimbristylis miliacea extracts were screened for their secondary metabolite constituents. All extracts at a concentration of 1% were also evaluated for their feeding and fumigant toxicity against Sitophilus oryzae. Phytochemical analysis showed the presence of terpenoids, saponin, and phenolics in Fimbristylis miliacea extract. Fimbristylis globulosa extract contains flavonoids, terpenoids and phenolic. Phenolic and flavonoid compounds are also included in Cyperus iria extract. However, Fimbristylis miliacea extract showed the strongest feeding toxicity against Sitophilus oryzae at a mortality of 100% at the highest concentration starting after 6 hours, while the other extracts had moderate feeding toxicity with a mortality rate (50-80%) at a low of concentration. Fimbristylis miliacea extract also showed a higher repellency in the fumigant toxicity at (100%) maximum in 5 hours.

PublicationAssessing changes in soil moisture distribution for before and after irrigation in a Harumanis Greenhouse( 2024-03)Soil moisture is an essential factor in determining the quality of crop production in farming areas, particularly in a greenhouse. It is important to ensure that the irrigation in the greenhouse can provide ample water needed by trees. This study aims to assess the status of soil moisture and map its distribution in a greenhouse following the irrigation supply. Soil samples were collected at forty randomly chosen locations at two different intervals of before and after irrigation supply. The soil moisture content is determined by the gravimetric method in the laboratory. Two soil moisture distribution maps were developed using soil moisture data and the coordinates of the sample locations. Based on the maps, the soil moisture distribution of before irrigation was classified into two classes: low and moderate at about 50% coverage each, while 100% of the greenhouse area was within the high soil moisture class for after irrigation. The statistical results demonstrate that both soil moisture data before and after irrigation are different, with the mean soil moisture content increased by 8.73%, thus proving that irrigation systems installed in the greenhouse work effectively by providing ample water to the soil to achieve high soil moisture content in the greenhouse.
