    Piper betle L. telah digunakan secara meluas dalam perubatan herba tradisional di Asia. Walau bagaimanapun, tumbuhan ini masih kekurangan data analisis terutama berkaitan kualiti, keselamatan dan keberkesanannya. Kajian ini telah dijalankan untuk menyediakan maklumat mengenai pemiawaian daun Piper betle. Kajian ini dibahagikan kepada tiga bahagian: kualiti dan keselamatan bahan-bahan mentah daun Piper betle, piawaian ekstrak Piper betle menggunakan sebatian terasing dan anti-obesiti. Daun kering Piper betle ditentukan untuk kandungan logam berat dan kandungan ujian had mikrob (MLT). Tumbuhan ini didapati berada dalam lingkungan had yang ditetapkan bagi empat logam berat Cd (0.3ppm), Hg (0.5 ppm), Pb (10 ppm) and As (5.0 ppm) dan ia bebas dari pencemaran mikrob. Pemeriksaan fitokimia awal bagi ekstrak etanol, ekstrak 50% etanol dan ekstrak air menunjukkan kehadiran sebatian terpenoid, flavonoid, fenol, sterol, koumarin dan saponin. Dua sebatian iaitu kavibetol (CHV) dan hidroksikavikol (HC) telah diasingkan dan dikenalpasti melalui data UV, FTIR, TLC, HPLC, GC-MS dan NMR. Profil kimia yang menggunakan teknik spektroskopi dan kromatografi seperti UV, FTIR, HPTLC dan GC-MS digunakan dalam kajian pemiawaian. Piper betle L. has been extensively used in traditional herbal remedies in Asia. Nevertheless, this plant still lacks of data especially on their quality, safety and efficacy. This study has been conducted to provide information on the standardization of Piper betle leaves. The study was divided into three parts: quality and safety of raw materials of Piper betle leaves, standardization of Piper betle extracts using isolation compounds and anti-obesity studies. Dry powdered leaves of Piper betle were determined to evaluate the content of heavy metals and the microbial limit test (MLT). This plant was found to be in the range of the acceptable limit of four main heavy metals Cd (0.3ppm), Hg (0.5 ppm), Pb (10 ppm) and As (5.0 ppm) and free from microbial contamination. The preliminary phytochemical screening using TLC on the ethanol, 50% ethanol and water extracts showed the presence of terpenoids, flavonoids, phenols, sterols, coumarins and saponins. Two compounds namely chavibetol (CHV) and hydroxychavicol (HC) were isolated and identified by UV, FTIR, HPTLC, HPLC, GC-MS and NMR data. The chemical profile using spectroscopic and chromatographic techniques such as UV, FTIR, HPTLC and GC-MS were used in the standardization

    The 2014 flood disaster in Kuala Krai has led to the significant destruction of property and the loss of life. This study argues that human interference in the ecosystems often invite risk and hazard in the flood drainage basin thus resulting to more frequent incidents with increasing intensity each year. Thus, the main objective of the study was to examine the effects of human and natural events that contribute to the severity of the floods in 2014 in Kuala Krai through land use change data and rainfall. In addition, a total of 300 people from three districts in Kuala Krai was used in this study evaluating the effectiveness of flood management systems.The results of the land use aspect showed many active land use activities at the survey spot mostly for sand mining, and opening of land for agriculture which covered an area of 6,930 hectars. While 34,850 hectars were for replanting, and 2,260 hectars for secondary jungle according to the 2014 data. This situation worsened when there was an unusual heavy rainfall in the Kuala Krai District in December 2014. To overcome the significant damage and the loss of lives due to flood, the government must implement the flood management system more effectively in the three phases of before, during and after the flood. According to the survey in the Kuala Krai District, the Dabong area had the the low min value (average) for the three phases: 3.04 (before), 2.99 (during) and 2.02 (after). Whereas for the Olak Jeram area the min value was 3.39 (before), 3.21 (during) and 2.30 (after). The one way ANOVA servey found that the people of Kuala Krai had different opinions about the management system of the before, during and the after phases. Whereas the satisfaction level was low at all the phases therefore giving the picture that the flood management system was unsatisfactory. This study suggests that the involvement of all parties in the flood management working draft must be integrated with the Directive 20 of the National Security Council so that future flood disaster management system would be more effective

    Keselamatan makanan : kepentingan kesedaran pengguna terhadap Halālan Ṭayyiban

    Get PDF
    Keselamatan makanan menjadi keperluan penting untuk diperhatikan oleh semua pihak termasuk pengguna. Selain halal, tayyiban merupakan salah satu kriteria penting yang digariskan Islam dalam pemilihan makanan. Aspek tayyiban merangkumi pelbagai elemen sepanjang rantaian makanan termasuk elemen kebersihan, kualiti, keselamatan dan kesihatan. Kesedaran merupakan faktor penolak yang mendorong seseorang bertindak untuk melakukan sesuatu. Namun, pengetahuan dan kesedaran tentang keselamatan makanan dalam kalangan pengguna masih berada di tahap yang tidak memuaskan. Oleh itu, kajian ini tampil untuk meningkatkan pengetahuan tentang keselamatan makanan sekali gus menampakkan kepentingan kesedaran tentang pemahaman konsep halālan ṭayyiban yang sebenar kepada pengguna melalui nas agama. Kajian ini dipraktikkan secara kajian kualitatif melalui pendekatan kajian kepustakaan dan analisis dokumen sebelum menganalisis maklumat yang berjaya dikumpulkan menggunakan kaedah induktif dan deduktif. Kajian ini mendapati pengabaian aspek keselamatan makanan akan memberi kesan kepada individu sama ada dari sudut sains atau maqasid. Pelbagai inisiatif khususnya melalui teknologi dan media sosial perlu digiatkan bagi meningkatkan kesedaran tentang keselamatan makanan. Tambahan lagi, pengguna berperanan untuk mengelak pengambilan makanan yang boleh mengundang mudarat, bahaya dan penyakit kepada diri. Oleh itu, kesedaran tentang keselamatan makanan yang sejajar dengan sumber wahyu iaitu al-Quran dan Sunnah sangat penting untuk diterapkan dalam kalangan pengguna

    Kajian ini dijalankan bagi meneroka perspektif guru berkaitan kemahiran berfikir aras tinggi (KBAT) dalam kalangan pelajar. Kajian ini menggunakan kaedah temubual separa berstruktur yang melibatkan seorang guru yang berpengalaman. Instrumen yang digunakan dalam kajian ini terdiri daripada protocol temubual dan komputer riba. Hasil kajian mendapati bahawa KBAT dalam kalangan pelajar masih perlu diperkasakan dan dipengaruhi oleh perbezaan tahap sosioekonomi dan jenis sekolah. Faktor pelajar, alat bantu mengajar, dan keadaan bilik darjah didapati mempengaruhi pemilihan strategi pengajaran bagi memupuk KBAT dalam kalangan pelajar. Hasil kajian turut mendapati bahawa teknik menyoal boleh digunakan bagi meningkatkan KBAT dalam kalangan pelajar, manakala pemberian soalan KBAT secara konsisten, penggunaan kaedah pembelajaran abad ke-21 (PAK21) dan pemberian tugasan berkumpulan boleh digunakan untuk menggalakkan aplikasi KBAT ketika pelajar menghadapi penilaian. Dapatan kajian turut menunjukkan bahawa kekangan masa dan faktor pelajar yang tidak aktif memberikan cabaran kepada guru untuk memupuk KBAT dalam kalangan pelajar. Sebagai implikasi, semua pihak perlu memainkan peranan yang sewajarnya dalam usaha meningkatkan KBAT dalam kalangan pelajar agar matlamat pendidikan dapat direalisasikan. Teachers' Perspectives on Higher Order Thinking Skills Among Students Abstract: This study was conducted to explore the perspectives of teachers related to high -level thinking skills (HLTS) among students. This study used a semi -structured interview method involving an experienced teacher. The instruments used in this study consisted of an interview protocol and a laptop. The results of the study found that HOTS among students still need to be empowered and influenced by differences in socioeconomic levels and types of schools. Student factors, teaching aids, and classroom conditions were found to influence the selection of teaching strategies to foster HOTS among students. The study also found that questioning techniques can be used to improve KBAT among students, while giving KBAT questions consistently, the use of 21st century learning methods (PAK21) and group assignments can be used to encourage the application of KBAT when students face assessment. The findings of the study also show that time constraints and inactive student factors provide a challenge to teachers to cultivate HOTS among students. As an implication, all parties need to play an appropriate role in efforts to improve HOTS among students so that educational goals can be realized.
