Reinforcement of multiwalled carbon nanotubesnatural rubber nanocomposite prepared by latex technology

Abd. Aziz Azira, Abang Ismawi Hassim Dayang Habibah, A. B. Suriani, Mahmood Mohamad Rusop,

Abstract

Reinforcement of natural rubber was achieved using multiwalled carbon nanotubes (MWCNTs) dispersed with non-ionic, polymeric-based surfactant. MWCNTs were first dispersed in aqueous solution of INUTEC driven by sonication and then mixed with natural rubber latex. From these mixtures MWCNTs with natural rubber were prepared by casting method. The morphology of the reinforced latex films was investigated by FESEM and AFM. When applying adequate preparation conditions, MWCNTs were well dispersed and homogeneously incorporated in the natural rubber matrix. Mechanical and electrical test results showed an increase in the tensile strength and conductivity than to pure natural rubber. The nanocomposites possess the good tensile strength even without extensive purification on the nanomaterials produced and without any pretreatment on the natural rubber used. The approach presented can be adapted to other MWCNTs/polymer latex systems...

Pembinaan manual pembelajaran berasaskan pemikiran: “Jom Fikir KdK” bagi Kegunaan guru pelatih

Nor Azira Kamarudin

Abstract

Kajian ini dilaksanakan bagi membina sebuah manual pembelajaran berasaskan pemikiran yang dikenali sebagai ‘Jom Fikir KdK’ dan mengenal pasti persepsi guru pelatih mengenai manual yang telah dihasilkan. Pembinaan manual ‘Jom Fikir KdK’ ini dikategorikan sebagai kajian reka bentuk dan pembinaan yang berteraskan model ADDIE. Kajian tinjauan pula dijalankan bagi mengenal pasti persepsi guru pelatih terhadap manual 'Jom Fikir KdK' dari aspek kandungan, reka bentuk dan penggunaan. Kajian tinjuan ini dijalankan di sebuah universiti di negeri Perak yang melibatkan seramai 80 orang guru pelatih yang berada di semester 8 dari program Sarjana Muda Pendidikan Sains, Biologi, Fizik dan Kimia. Manual 'Jom Fikir KdK' yang dibina ini mempunyai nilai kesahan 96% persetujuan pakar dan nilai kebolehpercayaan Cronbach Alpha 0.960. Kajian tinjauan terhadap persepsi guru pelatih menunjukkan bahawa manual ini berada pada tahap yang baik bagi ketiga-tiga aspek iaitu kandungan (min=4.42), reka bentuk .....

The efectiveness of dry cupping and hot pack on pain relief and reduced functional disability for patients with non-specific low back pain

Azira Iqlima Razali

Abstract

The objective of this study was to identify the effectiveness of dry cupping and hot pack on pain relief and reduced functional disability for patients with non-specific low back pain. The study design was experimental study using pre-test and post-test measurements. A total of 39 patients with non-specific low back pain from Sultan Idris Education University, Malaysia who fulfilled the inclusion criteria were recruited as subjects using purposive sampling methods. The subjects were randomly assigned equally (N=13) into dry cupping group, hot pack group and control group. Dry cupping group received a treatment session in a week for three weeks, hot pack group received two treatment sessions twice a week, and control group received no treatment, but continue previous treatment from general practitioner. Numerical Pain Rating Scale was used to measure pain intensity and Oswestry Disability Index was used to measure functional disability before and after the intervention for al.....

Penglibatan murid-murid sekolah kebangsaan di kawasan bandar dalam pembelajaran bahasa Melayu dalam talian daripada persepsi guru bahasa Melayu

Nurul Azira Sapian

Abstract

Semua guru mendepani pelaksanaan pengajaran norma baharu sepanjang tempoh Perintah Kawalan Pergerakan (PKP) akibat wabak Pandemik COVID-19. Perubahan corak pengajaran pendidikan konvensional memerlukan guru Bahasa Melayu memilih dan menguasai kaedah pengajaran dalam talian dengan berkesan. Kajian ini bertujuan untuk meninjau Penglibatan murid dalam Pengajaran dan Pembelajaran (PdP) Bahasa Melayu dalam talian daripada persepsi guru Bahasa Melayu. Kajian secara kualitatif ini melibatkan tiga orang guru Bahasa Melayu yang mengajar di tiga buah sekolah kebangsaan di zon Keramat, Kuala Lumpur. Data temu bual dianalisis secara bertema. Dapatan kajian menunjukkan bahawa kaedah pengajaran yang pelbagai ini telah mempengaruhi penglibatan murid- murid yang amat memberangsangkan dari segi kadar kehadiran murid, penghantaran tugasan, motivasi murid dan tingkah laku murid secara menyeluruh. Murid-murid menjadi aktif belajar Bahasa Melayu secara dalam talian yang diukur daripada kadar kehadiran yang.....

Shuhadayana Azira Sarifuddin

Abstract

Kajian ini dijalankan untuk membangunkan sebuah Bahan Bantu Mengajar (BBM) bagi topik Ungkapan Algebra Tingkatan Satu yang diberi nama Kit Geboard. Terdapat tiga objektif dalam kajian ini iaitu untuk menganalisis keperluan Pembangunan Kit Geboard, untuk membangunakan Kit Geboard yang memepunyai kesahan yang memuaskan dan untuk menilai kebolehgunaan kit tersebut. Kajian ini adalah kajian kuantitatif yang menggunakan reka bentuk Design and Development Research (DDR) dengan menggunakan model ADDIE. Sampel dalam kajian terdiri daripada 92 murid daripada jumlah populasi 120 murid Tingkatan Satu di sebuah Sekolah Menengah Kebangsaan Cenderawasih Kuantan, Pahang. Instrumen kajian yang digunakan berbentuk soal selidik digunakan, yang merangkumi tiga jenis iaitu: (a) Soal Selidik Analisis Keperluan, (b) Soal Selidik Penilaian Kit, dan (c) Soal Selidik Kebolehgunaan. Data kesahan penilaian Kit Geboard dianalisis menggunakan Indeks Kesahan Kandungan (IKK), manakala data analisis keperluan dan keb.....

Factors influencing farmer adoption of climate-smart agriculture technologies: Evidence from Malaysia

Noor Hadzlida Ayob

Abstract

As technology advances, people become increasingly dependent on technological tools to increase their work efficiency and productivity. Farming methods in the agriculture sector are also undergoing a shift from conventional to technology-driven modern agriculture practices, primarily because of their benefits and potential to mitigate the effects of climate change. However, the adoption rate of climate-smart agriculture technologies (CSAT) is considered to be very slow. Thus, this study was conducted to examine the factors that lead farmers to adopt CSAT in their agricultural practices. A sample of 185 farmers was used to investigate the main influencing factors in four contexts. The developed model was analyzed using the partial least squares structural equation modeling method. The results of this study suggest that institutions play a critical role as a contextual factor that leads individuals and societies to engage with CSAT, builds confidence, and convinces farmers to adopt these.....
