5G antenna design for smartphones / Muhamad Nur Firdaus Munir
No full textWith the rapid development in mobile communication technologies, rapid demands for efficient 5G antennas within smartphones at middle band frequency of 3.5 GHz are also on their market increase. Two of the major challenges involved are high costs of advanced dielectric material such as Duroid RT 5880 and size constraints within smartphone designs. The aim is to design a 5G antenna that resonates at 3.5Ghz antenna into smartphones using low-cost material that is FR-4 as substrate. Next, to observe and optimize the antenna design of rectangular and circular microstrip antennas to achieve efficient and compact mid band frequency for integration into smartphones using CST Studio Suite 2023. A couple of rectangular and circular microstrip patch antennas have been modelled and simulated using the CST Studio Suites 2023. Some of the cheaper alternatives are FR-4 lossy substrate with a dielectric constant £r = 4.3 and s = 0.02; this meets most of the performance specifications. Some of the parameters which have been studied are return loss, VSWR, gain, directivity, bandwidth, and size. Simulation results indicated that the best gain was provided by the rectangular patch antenna at 2.973 dBi and smallest in size, at 35.21*29.22 mm, which made it very appropriate for smartphones. The circular patch antenna showed a better bandwidth of about 0.1329 GHz with a VSWR of 1.0574 for impedance matching. In the end, the rectangular microstrip patch antenna presents a trade-off between performance and size, suitable for mid-band 5G smartphone integration. Future work should be done on optimizing designs for better performance with minimal size to meet the ever-evolving demands of next-generation communication devices
ENT 530 Social Media Portfolio: Sambal Tempoyak Tok Ayah / Muhamad Nur Syafawi Abdul Gani
Full text linkIn my social media portfolio, I have decided to choose a business related to food and beverages due to the demand for food are seemingly high especially since the Covid-19 pandemic. However, the supply for traditional food are still at a low level even though the demand is surprisingly high. This is because most people would think that no one would want to purchase traditional food and the profit will not be as much as selling modern food.
Therefore, I have chosen to sell Malaysian traditional condiment to gain advantage in the market by demonstrating modern presentation in marketing to attract people, changing their perspectives, and make traditional food great again while keeping it up with the advancement of technologies and standard of living. Therefore, I came out with the idea of selling Sambal Tempoyak Tok Ayah and decided to be an agent for this product to expand the business not only to old generations, but also to the younger generations. Haji Bahar, or familiarly known as Tok Ayah, is a founder of this business and have been selling it for years. However, the sales of his sambal tempoyak tends to decrease as he have a problem to reach out his agents and customers due to pandemic circumstances. It is because Haji Bahar prefer to operate his business in the traditional way and depending on the agents to do any further marketing, or post delivery the product.
In the making of this portfolio, I learn a lot on how to be a real time entrepreneur by constructing plans, marketing idea, determine product pricing and using Facebook platform to reach out potential customers. I have learned precise marketing techniques in order to conduct teaser, soft sell and hard sell of the product. I also need to produce the graphic contents and editing for marketing purpose. By using Facebook page, I can easily familiarized myself on how do I starts to setup the basic profile of the business, besides starting small to deal with my anxiety by building confidence in managing online business

Influence of inhibitor on corrosion behaviour of Al-Mg alloy / Muhamad Nur Irfan Mohd Adly
No full textFrom pure aluminium to a series of aluminium alloy, the evolution of the steel led by a continuous demand for a superior and more efficient steel. Since then, aluminium alloy have been employed in numerous engineering applications such as engine parts, marine applications, and other applications demands the large volumes of aluminium alloys. However, Al-Mg are exposed to continuous attacks from corrosion, thus usage of corrosion inhibitors is necessary to enhance Al-Mg corrosion resistance. The aim of this research is to study the previous literature journal on the effect of inorganic inhibitor on Al-Mg in corrosive media and surface morphology of Al-Mg with or without inorganic inhibitors from.
Electrochemical corrosion testing was performed on Al-Mg alloy with various type corrosive media and inorganic inhibitor. The corrosion mechanism with or without inhibited on Al-Mg was observed by potentiodynamic polarization study. Scanning electron microscopy (SEM) and energy dispersive X-ray spectroscopy (EDS) were used to investigate the surface microstructure morphology. The result from the reviewed journal shows that the Al-Mg was seriously corroded under acidic corrosive media due to the aggressive ion. Addition of inorganic inhibitors such as chromates, molybdates, phosphates and nitrates proved to reduce the rate of corrosion of the Al-Mg alloy. The result from the literature also confirmed that higher concentration will give a better corrosion protection. Inorganic inhibitor molecules suppress corrosion by adsorbing to the alloy surface, forming an exterior protective coating that prevents corrosion. The result was confirmed and reviewed by the electrochemical measurements, scanning electron microscopy (SEM) as well as energy dispersive X-ray spectroscopy (EDS)

Study on the compressive strength of concrete using construction and demolition waste as aggregates / Muhamad Nur Syafiq Mokhtar
No full textThe disposal of construction and demolition waste in landfills has caused major environmental concerns in country such as Malaysia, Hong Kong and European Union. Government of Malaysia sources indicate that there is an acute shortage of landfill space in Malaysia. To overcome this problem, suggestion to recycle the construction and demolition waste to be used in concrete mix as a coarse aggregate was given. To prove that this idea can be used, some experiment need to be done. The four types of concrete that will be mix and test are normal concrete, concrete with containing 10% construction and demolition waste aggregate, concrete with containing 20% construction and demolition waste aggregate and concrete with containing 30% construction and demolition waste aggregate. The sizes of specimen are 100mm x 100mm x 100mm cube for compressive strength test. The testing have been carried out at the age 7,14 and 28 days for all specimens of concrete. The scope relates to the material and equipment that involved in this study and full fill the requirement according to standard BS 1881: Part 116:1983.According to the experiment test result, the value of compressive strength with 0% contents of construction and demolition waste are the highest, follow by the value of compressive strength with 10% contents of construction and demolition waste, than follow by the value of compressive strength with 20% contents of construction and demolition waste and the lowest value of the compressive strength fall to 30% contents of construction and demolition waste. The value of compressive strength that produced by all the three different percentage of construction and demolition waste, it show that all the three concrete mix comply and pass the target of concrete that use for this experiment it is Grade 20. Because of that, once again we can conclude that the construction and demolition waste can be used as a coarse aggregate in the concrete mix

Muhamad Nur Rivaldi (2023) : PEMBERIAN NAFKAH KELUARGA DARI
HASIL PENAMBANGAN EMAS DI
KECAMATAN KUANTAN MUDIK
MENURUT TINJAUAN HUKUM ISLAM
Penelitian ini dilatar belakangi oleh menipisnya lapangan pekerjaan dan
juga masih banyaknya pengangguran membuat persepsi tentang nafkah itu sendiri
juga mengalami perubahan yang menyesuaikan perkembangan. Maka dari itu,
masyarakat mulai mengembangkan alat untuk menambang emas yang mana
bertujuan untuk menaikkan pendapatan emas perharinya dan alat inilah yang
kemudian dikenal masyarakat sekitar dengan Dompeng. Namun dengan naiknya
pendapatan emas perhari dengan menggunakan alat ini, menimbulkan masalah
lain bagi lingkungan sungai.
Adapun yang menjadi permasalahan dari penelitian ini adalah pertama,
bagaimana pemberian nafkah keluarga dari hasil penambangan emas di kecamatan
Kuantan Mudik, kedua, bagaimana tinjauan hukum Islam terhadap penambangan
emas di kecamatan Kuantan Mudik.
Penelitian ini adalah penelitian yuridis sosiologis, karena didasarkan pada
penelitian lapangan yaitu dengan mengumpulkan data dari observasi, wawancara,
dan dokumentasi yang memiliki kaitannya dengan permasalahan yang
mengggunakan analisis data deskriptif kualitatif, menghasilkan data deskriptif,
dan disimpulkan dengan metode berfikir deduktif.
Dari hasil penelitian didapatkan bahwa nafkah dari hasil dompeng yang
dilakukan masyarakat tidak sesuai dengan hukum Islam, disimpulkan bahwa,
pertama, berpindahnya mata pencaharian utama yang sebelumnya merupakan
petani karet menjadi pendompeng ini didasarkan pada pendapatan yang
didapatkan dari hasil pendompengan lebih menjanjikan dibandingkan dengan
bertani karet. Kedua, dilihat dari kaidah kepemilikan dan perizinan kegiatan
pendompengan di kecamatan Kuantan Mudik tidak sesuai dengan konsep
kepemilikan dalam Islam yang menyebutkan kalau sungai yang dijadikan tempat
untuk pendompengan tersebut, merupakan suatu pemilikan negara yang tidak
dapat dimiliki secara individu.
Kata Kunci : Pemberian Nafkah - Penambangan Ema
