    A 3-D printed dielectric lens for gain enhancement of horn antenna from 18 GHz to 40 GHz is presented in this paper. Fused deposition modelling (FDM) is used to fabricate the Acrylonitrile butadiene styrene (ABS) lensas it is one of the well-known 3-D printing techniques. The results with and without dielectric lens are analyzed and compared from the simulation. From simulation results with thedielectric lens, a maximum gain of 26.7 dBi was achieved. The dielectric lens of 21.72 mm thickness was able to provide a gain enhancement up to 26.7 dBi when compared to the simulation result without the dielectric lens. The proposed dielectric lens can improve the gain of the horn antenna as good agreement between literature, simulation and measurement was achieved.

    The shift from paper-based to web-based practice is a significant trend, as paper-based practice consumes time, is prone to error, and is more prone to data loss, all of which lead to inefficiency. Smart farming or agriculture 4.0 defined the new era of agriculture that moving toward digitalization. However, the absence of a centralized information system, which results in information asymmetry among agricultural sectors. One of the keys to success is reaching out to farmers with pertinent agricultural information at the appropriate time and platform. The purpose of this study is to design and create a dynamic web-based knowledge management system for the dissemination of agricultural knowledge in Malaysia. A centralized information system capable of achieving information symmetry, in which all important information is accessible to all participants. Creating an advanced learning environment allowing for virtual engagement between external and internal stakeholders via a web-based knowledge management system.
