Publication Functional Group And Phytochemical Properties Detection Of Peperomia Pellucida Leaves Extract(ASIAN SCHOLARS NETWORK, 2023) ;Nurul Syamimi Norisham ;Faiqa Husna Mohamad Mulfazir ;Muhammad Zulfikar Firas Putra Zulpakar ;Luqman Nur Hakim Paharudin ;Ahmad Hakimi Shaffie ;Liyana Amalina Adnan ;Ehwan NgadiRahayu AhmadSince prehistoric times, medicinal plants, often known as medicinal herbs, have been identified and employed in traditional healing practises. Because of the existence of phytochemical ingredients, medicinal plants synthesise hundreds of chemical compoundsand are a key source of molecules with therapeutic qualities. Wild herb leaves were taken from the green region of Universiti Sains Islam Malaysia, specifically Peperomia pellucida, also known as 'sireh cina' in Malaysia. The dried wild herb leaves were crushed. For 48 hours, the powdered materials were treated to a solid-liquid extraction method utilising hot water and ethyl acetate as a solvent. For all examined samples, a phytochemical screening test of hot water and ethanolic leaves extract confirmed the presence of antioxidant chemicals such as flavonoid and phenolics. Meanwhile, resins were only found in ethanolic leaves extract, and steroid was not found in any of the studied samples. Fourier-Transform Infrared Spectroscopy (FTIR) was used to study the organic component in greater depth by evaluating the chemical ingredients in the crude extracted samples of ethyl acetate. The study of FTIR spectra revealed that the hydroxyl group, alkanes, alkyl groups, benzoic compounds, and phenols were the primaryfunctional groups. The identification of functional groups indicates a possible source of antioxidants and highlights a potential prospect for the development of natural products from these wild plants in the drug discovery business. Disc diffusion analysis of antibacterial properties exhibited significant clear zone formation against Gram-positive and Gram-negative tested bacteria. - Some of the metrics are blocked by yourconsent settings
Publication Kecenderungan Minat Murid Pintar Dan Berbakat Muslim Dalam Bidang Sains(2022-11-29) ;Muhammad Abrar Zamri ;Norazlina Subani ;Rosita Zainal ;Ehwan Ngadi ;Mohamad Azani Abd Kadir Jailani ;Liyana Amalina Adnan ;Ahmad Hakimi Shaffie ;Faizatul Atirah Fadzil ZabideeAdnan Mohamed YusoffMurid pintar dan berbakat mempunyai kebolehan dalam mempertingkatkan potensi diri untuk memastikan prestasi yang cemerlang dan seterusnya memperoleh pencapaian tertinggi jika dibanding dengan murid lain seusia mereka. Sehubungan itu, murid pintar dan berbakat mendapati sistem pendidikan semasa berada pada tahap yang rendah atau sederhana selaras bedasarkan umur akal mereka. Satu kajian telah dilaksanakan tentang pemetaan kecenderungan sains dan hafazan Al-quran dalam kalangan murid pintar dan berbakat muslim di Malaysia. Soal kaji selidik telah digunakan sebagai penanda aras kecenderungan murid. Seramai 466 orang murid Kolej GENIUS Insan telah dikenalpasti sebagai responden dalam kajian ini. Tujuan kajian ini dijalankan adalah untuk mengenal pasti dan mengelaskan kecenderungan murid terhadap bidang sains yang memfokuskan pemikiran logik dan juga hafalan seperti Matematik, Matematik Tambahan, Fizik, Kimia dan Biologi melalui soal kaji selidik yang telah dijalankan di kalangan murid pintar dan berbakat muslim.
