Nilai pendidikan berasaskan makna simbol seni kraf masyarakat gayo pasca konflik dan tsunami dalam konteks sosialisasi

Abstract

Kajian ini bertujuan untuk memberikan maklumat yang jelas secara teoritikal dalam disiplin seni kraf tentang bentuk seni kraf Gayo, motif-motifnya serta fungsi dalam konteks masyarakat Gayo. Seni kraf tradisional Gayo merupakan salah satu hasil kraf tangan dalam masyarakat yang terkandung didalamnya falsafah, moral dan nilai-nilai pendidikan dalam kehiduapan masyarakatnya yangdiwarisi sejak turun temurun. Pengumpulan data dilakukan dengan cara temu bual dengan tukang kraf, pentadbir pada jawatan Dewan Kraf Nasional Daerah dan masyarakat yang dianggap mengetahui tentang perwujudan makna simbol dalam Seni Kraf, serta dengan teknik pemerhatian dan perakaman visual seni kraf dan analisis dokumen dengan menghimpun penulisan artikel yang berkait erat dengan Seni Kraf. Analisis data dilakukan dengan model interaktif oleh Miles dan Huberman dan pengumpulan data dengan mengatur hasil temu bual, catatan lapangan dan benda lainnya yang berguna bagi peningkatan pemahaman pengkaji mengenai subjek k.....

Thickness dependant effective radius of an optical trapping toward water-air interface

Muhamad Safuan Mat Yeng

Abstract

This study aimed to determine the effect of sample thickness on optical trapping towards water-air interface. 3 µm polystyrene bead was diluted in deionised water and transferred to special test cell design to form 18, 70 and 141 µm. Bead was trapped by 975 nm laser from 20 to 220 kW/cm2 from the bottom glass-water interface towards water-air interface. The result showed that the bead is more confined with smaller effective radius in higher water thickness. ..

The determination of an effective radius of an optically trapped polystyrene microbead distribution near a water air interface

Muhammad Safuan Mat Yeng@Mat Zin

Abstract

The research aimed to determine the effective radius (r*) of a trapped polystyrene microbead near a water-air interface and to develop a 3-dimensional piezostage control module for optical trapping within micrometre range. This study involved the development of a control program so called PZStage and the determination of r* near the water-air interface. PZStage was developed on the LabVIEW platform to control laser focus location in the trapping medium. A 3 µm bead was trapped in water at several heights towards the free space in a special design test cell. The temporal displacement data of the trapped bead was recorded by a quadrant photodiode (QPD) and analysed by a custom made program namely OSCal to determine r*. PZStage was well developed which enabled precise laser focus control in 20 µm range in three mutually orthogonal directions. The result showed that r* was constant at any focus height at fixed water thickness and laser power. .....

Pengaruh demografi dan amalan kemahiran PAK-21 oleh guru pelatih bagi subjek Matematik semasa pandemik COVID-19

Muhammad Safuan Sahak

Abstract

Kajian ini bertujuan untuk mengukur tahap amalan kemahiran PAK-21 semasa pandemik COVID-19 oleh guru pelatih bagi subjek Matematik dan juga bertujuan untuk mengukur perbezaan amalan kemahiran PAK-21 semasa pandemik COVID-19 oleh guru pelatih bagi subjek Matematik berdasarkan faktor demografi seperti umur, jantina dan kawasan penempatan latihan mengajar. Kajian ini menggunakan pendekatan kuantitatif dengan kaedah tinjauan. Seramai 92 orang guru pelatih terlibat dalam kajian ini yang terdiri daripada dua program berbeza iaitu program Ijazah Sarjana Muda Pendidikan Matematik dan juga program Ijazah Sarjana Muda Sains (Matematik) dengan Pendidikan. Kaedah persampelan yang digunakan dalam kajian ini ialah persampelan rawak mudah. Secara keseluruhannya, kesemua objektif kajian telah tercapai dan persoalan kajian juga terjawab di mana guru pelatih yang mengamalkan kemahiran 4C dalam sesi PdPR semasa pandemik COVID-19 adalah pada tahap yang tinggi, amalan 4C dalam sesi PdPR yang diamalkan guru.....

Optical trapping of a single chloroform microdroplet in water

Muhamad Safuan Mat Yeng

Abstract

The study aims to optically trap a single chloroform (CHCl3) microdroplet in water using optical tweezers. The study also investigates the effect of the preparation procedure by sonication on the chloroform microdroplet size and its stability in water. This microdroplet can potentially act as a carrier containing active molecules and for sensor applications in a fluid. The chloroform is sonicated in deionized water to produce a chloroform microdroplet solution. The size of the resultant microdroplets is observed under the optical microscope. The stability of the chloroform microdroplets in water was studied by monitoring the absorption spectra within a specified duration of time for 1 hour. A single chloroform microdroplet in the water is trapped using a 976 nm continuous laser beam with optical tweezers. The finding shows that the average size of the produced chloroform microdroplets does not vary significantly when the sonication time is less than 10 minutes. Furthermore, Chloroform .....

Quantitative optical manipulation of a single 4-Cyano-4'-pentylbiphenyl microdroplet in water for actuating and sensing applications

Muhamad Safuan Mat Yeng@Mat Zin

Abstract

The study aims to formulate the production of 4-cyano-4’-pentylbiphenyl (5CB) microdroplets within a suitable range to be optically trapped, to optically trap a single 5CB microdroplet in water within a suitable size range, to optically micro-control the microdroplet using a circularly polarized laser, and to quantitatively determine factors affecting the optical manipulation of the microdroplet. 0.5 μL 5CB was mixed with the deionized water and sonicated to produce bipolar and radial 5CB microdroplet suspensions. The 5CB microdroplet was observed under optical microscopy and its size distribution was measured using ImageJ, while its stability was measured using UVVis spectroscopy. A linearly polarized laser beam of 976 nm wavelength was used to optically trap a single 5CB microdroplet in water at a specific laser power density. A circularly polarized laser beam was used to optically trap a single 5CB microdroplet to study its orientation control, rotatability control, an.....
