Abstract

This study was carried out to survey on the implementation of Integrated Science Process Skills (KPSS, it acronym in the Malay language) in Form Two KBSM Science Curriculum in secondary schools as implemented in the Hilir Perak District. The study was carried out by observing the teachers as individuals who are directly involved in the implementation process to get the picture of how the integrated science process skills that was being recommended in the science curriculum is being implemented in the Hilir Perak District. The Test of Integrated Science Process Skills (TIPS) was used to test the science teacher’s mastery level in the five key aspects of KPSS in the secondary schools in the Hilir Perak District. A case study, focusing on the five key aspects was constructed. Interviews and observations were carried out to look in detail the ability of the teachers in performing and implementing KPSS in the classrooms. The findings based on TIPS shows that overall the mastery level of t.....

Determination of mercury(II) by single-walled carbon nanotubes paste electrode modified with zincaluminium layered double hydroxide-3(4-methoxyphenyl) propionate nanocomposite

Sharifah Norain Mohd Sharif

Abstract

This study aimed to develop a mercury(II) sensor and to identify its ability in mercury(II) determination. A mercury(II) sensor was developed by using singlewalled carbon nanotubes (SWCNTs) paste electrode modified with ZnIAl layered double hydroxide-3(4-methoxyphenyl)propionate nanocomposite (ZnIAI-LDH-MPP). Determination of optimum conditions for the detector was done by voltammetry method and subsequently confirmed by the double potential-step chronocoulometry. The results show that the optimum conditions were observed at electrode composition 2.5% (w/w) of ZnIAI-LDH-MPP/SWCNTs, OA M potassium chloride, pH 4.0, and scan rate of 100 mV S-I. The sensor exhibited wide linear range from 1.0 x l O" M to 1.0 x1O-3 M mercury(II) and 1.0 xl O" M to 1.0 xlO-7M mercury(II), with a detection limit of 1.0 xlO-lO M mercury(II). The high sensitivity of the proposed electrode towards mercury(II) was confirmed by double potential-step chronocoulometry which indicated these values; diffusion coeffic.....

Soffi Siti N. Shahshina, M. Sharif Ahmad,

Abstract

Kejayaan transformasi pendidikan vokasional yang dilancar oleh kerajaan Malaysia pada 2014, banyak bergantung kepada daya kepimpinan pengarah dan prestasi tenaga pengajar kolej vokasional yang dinaik taraf. Sejajar dengan senario masa kini, kajian ini berhasrat untuk menyingkap kepimpinan transformasi pengarah kolej vokasional dan juga efikasi kendiri pensyarah kolej vokasional. Kajian ini juga bertujuan untuk mengukur pengaruh kepimpinan transformasi pengarah kolej vokasional terhadap efikasi kendiri pensyarah kolej. Sampel kajian terdiri daripada 152 orang pensyarah yang dipilih secara rawak daripada tujuh buah kolej vokasional di Negeri Sembilan dan Melaka. Borang soal selidik mengandungi dua instrumen, Multifactor-Leadership Questionnaire (MLQ) dan Teacher Sense of Efficacy Scale (TSES) masing-masing bagi mengukur tahap kepimpinan transformasi dan efikasi kendiri. Analisis data melibatkan kekerapan, min, peratusan, sisihan piawai, ujian-t, ANOVA dan regrasi berganda. Kajian menunju.....

Controlled release formulation of paddy pesticides intercalated layered metal hydroxide via polysaccharide encapsulation

Sharifah Norain Mohd Sharif

Abstract

This research aimed to synthesis intercalated nanocomposites of paddy pesticides for controlled release formulation (CRF), namely zinc/aluminium–layered double hydroxide–quinclorac (Zn/Al–LDH–QC), zinc hydroxide nitrate–sodium dodecylsulphate–bispyribac (ZHN–SDS–BP) and zinc hydroxide nitrate–sodium dodecylsulphate–imidacloprid (ZHN–SDS–IC) using coprecipitation method. Surface modification of the nanocomposites, were then performed using carboxymethyl cellulose (CMC) and chitosan coatings. The physicochemical properties, CRF and kinetic behaviour were monitored using powder X–ray diffraction (PXRD), thermogravimetric analysis, Fourier transform infrared spectroscopy (FTIR), elemental analysis, field emission scanning electron microscopy (FESEM), gas sorption analysis and ultraviolet–visible spectrometer. The appearance of intercalation peaks at lower 2θ angle in the PXRD pattern, 15.8–16.7 ? (Zn/Al–LDH–QC), 28.2–28.6 ? (ZHN–SDS– BP).....

Muhamad Shazielan Sharif

Abstract

Kajian ini bertujuan untuk menentukan pengaruh aspirasi kerjaya dan kepuasan pekerjaan terhadap perkembangan kerjaya wanita dalam bidang pekerjaan teknikal. Reka bentuk tinjauan telah digunakan dalam kajian ini. Di samping itu, pendekatan kualitatif dalam bentuk temu bual telah dijalankan dalam kajian ini bagi menyokong data kuantitatif yang diperolehi. Sampel kajian seramai 105 orang pekerja wanita yang terdiri daripada 41 jurutera, 26 juruteknik dan 38 penyelia telah dipilih secara rawak berkelompok di sektor pembuatan di Semenanjung Malaysia. Instrumen kajian terdiri daripada satu set soal selidik dan protokol temu bual yang telah disahkan oleh tujuh orang pakar. Data kajian dianalisis secara deskriptif menggunakan kekerapan, peratusan, min dan sisihan piawai. Statistik inferens iaitu korelasi dan regresi juga telah digunakan untuk menguji 10 hipotesis.....

Kursus Asuhan Permata: implikasi terhadap kualiti amalan pengasuhan kanak-kanak

Muhammad Haziq Mohd Sharif

Abstract

Kualiti perkhidmatan Taman Asuhan Kanak-kanak (TASKA) bergantung kepada kualiti pengasuh. Oleh itu, kajian ini bertujuan untuk mengenal pasti perbezaan kualiti amalan pengasuhan antara pengasuh TASKA yang memiliki dan tidak memiliki Sijil Kursus Asuhan PERMATA (KAP). Kajian kes ini melibatkan empat orang pengasuh daripada empat buah TASKA swasta yang dipilih secara persampelan bertujuan. Data diperoleh melalui temu bual semi struktur dan pemerhatian bukan struktur menggunakan catatan nota lapangan. Hasil analisis tematik mendapati kedua-dua orang pengasuh yang memiliki Sijil KAP dengan pengalaman lebih tiga tahun dan kurang tiga tahun menunjukkan amalan pengasuhan yang lebih baik dalam penjagaan dan pengurusan keperluan asas kanak-kanak dan pelaksanaan aktiviti bersama kanak-kanak berbanding dua orang pengasuh yang tidak memiliki Sijil KAP dengan pengalaman lebih tiga tahun dan kurang tiga tahun. Dua orang pengasuh memiliki Sijil KAP tersebut juga mengakui KAP sebagai keperluan meni.....

The effect of swellable carboxymethyl cellulose coating on the physicochemical stability and release profile of a zinc hydroxide nitrate-sodium dodecylsulphate-imidacloprid

Sharifah Norain Mohd Sharif

Abstract

The environmental pollution that results from the excessive usage of pesticides has been threatening the communities for decades. In this study, carboxymethyl cellulose (CMC) is proposed as a coating agent to encapsulate zinc hydroxide nitrate?sodium dodecylsulphate?imidacloprid (ZHN?SDS?IC) for the implementation of controlled release formulation (CRF) in pesticide. The physicochemical properties of the ZHN?SDS?IC?CMC were characterised so that their crystallinity, thermal behaviour and surface morphology could be examined. The findings from the release study revealed the potential for CMC to prolong the release of imidacloprid (IC). A strong hygroscopic and adequate swelling characteristic enabled the CMC to develop an external gel layer on the surface of the ZHN?SDS?IC?CMC that acted as an additional barrier and slowed the release of the intercalated IC. The ZHN?SDS?IC?CMC that was synthesised can contribute to overcoming the environmental issues due to excessive usage of pesticides.....
