Keberkesanan cerpen dalam mempertingkatkan prestasi penulisan karangan Bahasa Melayu dalam kalangan murid

This research analyses the effectiveness of literature texts to upgrade the performance of 64 average-achiever students in Form Two. This experimental research was conducted to compare the effectiveness of the use of literature texts and conventional methods of teaching composition. Both groups were given two tests, namely pre-test and post-test to compare the performance of the overall composition, elaboration of points and sentence type. The research findings of the pre-test and post-test show that the teaching of composition using the literature texts is more effective than the conventional method

Lateral flow immunoassay for naked eye detection of Mycobacterium tuberculosis

Tuberculosis (TB) is an infectious disease caused by Mycobacterium tuberculosis. Detection and control of infectious diseases is a major problem, especially in developing countries. Lateral flow immunoassay (LFIA) has been introduced as a handheld immunoassay-based point-of-care platform for an automated detection of TB. The CFP10-ESAT6 antigen of M. tuberculosis was used as the target in early detection of TB using LFIA strip-based POC strategy. An interesting platform based on optical signals is implemented as a colour change in the detection area that is visible to the naked eye. The gold nanoparticles (AuNPs) were used as the colour probe for the detection of a target of interest. The high-resolution transmission electron microscopy (HRTEM) image and ultraviolet-visible spectrophotometer (UV-Vis) analysis confirmed that the synthesized AuNPs were appropriate for the immunoassay designed. The platform consists of AuNPs conjugated with specific antibodies (Ab) to capture the antigen of M. tuberculosis. Under the capillary effect, sandwich immunoreactions of AuNP-Ab-antigen were performed on the test pad of the immunostrip, which can be observed by the colour signal on the test line of the strip with a short assay time. Furthermore, the newly developed biosensor was utilized in CFP10-ESAT6 antigen detection in human sputum specimens with satisfactory results. The characteristic coloured bands enable visual detection (naked eye) of target analyte without instrumentation. This noninvasive diagnose system which is sputum-based detection could provide user-friendly and affordable diagnostic tests in developing countries

Keberkesanan cerpen dalam mempertingkat prestasi penulisan karangan Bahasa Melayu dalam kalangan murid (The effectiveness of literary text in enhancing the performance of Malay Language writing among students)

Kemahiran menulis merupakan kemahiran yang paling sukar diajarkan dan dikuasai oleh seseorang murid. Oleh hal yang demikian, kajian ini adalah untuk menganalisis keberkesanan penggunaan teks KOMSAS terhadap prestasi penulisan karangan 64 orang murid tingkatan dua berpencapaian sederhana. Kajian berbentuk eksperimental ini dijalankan untuk membandingkan keberkesanan menggunakan teks KOMSAS dengan kaedah pengajaran konvensional dalam pengajaran penulisan karangan. Kedua-dua kumpulan telah diberikan dua ujian, iaitu praujian dan pascaujian untuk membandingkan prestasi penulisan karangan dalam aspek karangan keseluruhan, aspek pengembangan isi karangan dan aspek penggunaan jenis ayat. Dapatan kajian dalam praujian menunjukkan bahawa bagi aspek karangan keseluruhan, skor min murid kumpulan eksperimen ialah 53.87 (SP = 9.40) dan skor min murid kumpulan kawalan ialah 48.65 (SP = 7.40). Ujian-t pula menunjukkan bahawa terdapat perbezaan skor min yang signifikan, iaitu t(31) = 2.840, p<.05. Manakala pada pascaujian pula, skor min murid kumpulan eksperimen mencatatkan 60.2 (SP = 10.44), dan murid kumpulan kawalan mencatatkan skor min 51.28 (SP = 8.53). Hasil analisis ujian-t menunjukkan terdapat perbezaan yang sangat signifikan antara kumpulan murid ini dalam aspek karangan keseluruhan pada t(31) = 4.532, p < .05. Kesimpulannya, kaedah pengajaran penulisan karangan menggunakan teks KOMSAS terbukti lebih berkesan berbanding kaedah pengajaran konvensional terhadap prestasi penulisan karangan murid. Justeru, diharap hasil kajian ini dapat memberi galakan kepada guru-guru Bahasa Melayu supaya menggunakan teks KOMSAS dengan lebih berkesan untuk membantu murid menjana idea bagi menghasilkan karangan yang baik

Electrochemical immunosensor for detection of Mycobacterium tuberculosis

A rapid and sensitive sandwich electrochemical immunosensor was developed based on the fabrication of the graphene/polyaniline (GP/PANI) nanocomposite onto screen-printed gold electrode (SPGE) for detection of Mycobacterium tuberculosis (M. tuberculosis) antigen. The chemical bonding and morphology of GP/PANI-modified SPGE were studied by Raman spectroscopy and field enhance scanning electron microscopy-energy dispersive X-ray spectroscopy (FESEM-EDX), respectively. From both studies, it clearly showed that GP/PANI was successfully coated onto SPGE through drop cast technique. Cyclic voltammetry (CV) was used to study the electrochemical properties of the modified electrode. The effective surface area for GP/PANI-modified SPGE was enhanced when compared with bare SPGE. Differential pulse voltammetry (DPV) was used to detect the M. tuberculosis antigen. This proposed electrochemical immunosensor is sensitive, low sample volume, rapid, and disposable, which is suitable for tuberculosis detection in real samples
