Implementasi Project-Based Learning Di Sekolah Menengah Kejuruan

The present study was aimed at mapping the model configurations of project-based learning implemented as curricular activities in several vocational schools in the municipality of Malang. For the purpose, an exploratory survey and in-depth observation were performed at 8 vocational schools, offering 14 vocational programs and involving 24 teachers and 62 groups of students, each of whichconsisting 2-5 students. The study found: 1) the project-based learning modes in several vocational schools in Malang could be categorized into three model configurations characterized by the implementation of the very simple to the complex and ideal ones. The first configuration placedproject work as a medium for the development of vocational skills and the teachers played dominant roles in the completion of students' project works. The second configuration placed project work as a medium for putting theoretical and practical learning as close as possible, but teachers' control over project completion was still greatly dominant. The third configuration placed project work as amedium for integrating theoretical-practical learning, collaborative learning of solutions to contextualproblems provisioning more autonomy to the students in the decision making process for project work completion. The third configuration was considered as the most ideal model in project-based learning

Factors associated with newly diagnoses HIV-positive among antenatal mothers in prevention of mother to child transmission (PMTCT) program in Kelantan

Background: Vertical transmission is common and important mode of HIV transmission in children and without intervention, 30% to 45% will be infected with HIV from the mother during pregnancy, the delivery of the baby or breast feeding. Malaysia embarked on national PMTCT Program in 1998. It covers four strategies: a) primary prevention of HIV for PMTCT; b) preventing unintended pregnancies among HIV-positive women; c) preventing vertical transmission or HIV transmission from women to their infants; and d) providing care, treatment and support for mothers with HIV and their children. Safer modes of delivery which usually caesarean section are applied in these strategies and replacement feeding to baby born from HIV positive mothers will be supplied by MOH until the baby is 24 months old. Objective: This study aims to describe and determine associations of sociodemographic, obstetric history and risks of mothers and husband with newly diagnosed HIV-positive antenatal mothers in PMTCT program in Kelantan from 2009-2017

Influence of Deposition Parameter to Wear Behaviour of Tungsten Carbide-Nickel (WC-Ni) High Velocity Oxyfuel (HVOF) Coating

This study is done to investigate the influence of deposition parameter to the hardness and wear resistance of the tungsten carbide nickel (WC-Ni) High velocity oxy-fuel (HVOF) coating which is sprayed on the AISI 1040 medium carbon steel. Three different spraying parameters were used with the oxygen flowrate of each being changed and all other parameters and its value is kept constant. Oxygen flowrate of 30, 45 and 60 LPM were used. The result of hardness, wear rate and surface morphology were compared between the coatings. To compare the surface morphology of the three different parameter HVOF coatings, a scanning electron microscope was used. No significant changes shown on the surface of the coatings where all shows the same lump and crevices structure. X-ray diffraction was used to observe the elemental composition on the three coatings, all the coatings have the same elements present on them. It can be seen that all the coatings contains nickel, tungsten carbide, tungsten (II) carbide and oxygen. The method used for hardness test was the Vickers microhardness tester while weight loss test was used to study the wear resistance. Following the test, it is found that the hardness and wear resistance increased as the oxygen flowrate was increased. The highest hardness and wear resistance can be found in the coating with 60 LPM oxygen flowrate

A Non-Invasive Method for Extraction of Fetal Heart Sound Signals using a Statistical Tool

In this paper, we present a novel approach to analyze and process the fetal heart sound signals (FHS). The proposed enhanced method extracts fetal heartbeat signals from the signal recorded by placing the mics on the mother?s womb. The signals collected are processed by signal processing approach based on Blind Source Separation (BSS) technique. The approach shows that ICA can be efficiently used as a statistical tool for Blind Source Separation (BSS) and to process acoustic phonocardiograph. The experimental results obtained by the proposed technique are encouraging and shows the accurate extraction of the fetal heart sound signals. The output of the proposed method can be further used to analyze the heart rate of the fetus

Deposition of ZnO-Al (AZO) thin films for optical properties

Zinc Oxide (ZnO) is an inorganic compound and it is doped with aluminum to increase its capabilities. Aluminum Zinc Oxide (AZO) thin films are semiconductor materials that have band gap energy of 3.3eV. Various method of deposition have been study to growth AZO thin films. It has been extensively use in solar cell application, display application, gas sensing purposes, and thin film transistors (TFTs). In this work, sol gel method and spin coating was used to deposited AZO thin films. The ZnO sol-gel were synthesized using zinc acetate dihydrate as precursor, isopropanol as solvent, diethanolamine as sol stabilizer, and distilled water as oxidation agent. Then, synthesized ZnO were doped with different mole ratio of aluminum nitrate nanohydrate to produced AZO. The glass substrate was used as substrate and AZO thin films were then calcinated at 300°C and 500°C. The characterization of AZO thin film were done using X-ray Diffraction (XRD), Atomic Force Microscopy (AFM), Ultraviolet-visible spectroscopy (UV-Vis), Field Emission Scanning Electron Microscope (FESEM), and Energy Dispersive X-ray spectroscopy (EDX). The XRD results show that the ZnO with hexagonal wurtzite-type structure and temperature does have effect on the film intensity which related to crystallinity of thin films. Through AFM analysis, the value of RMS decreases from 3.018 nm to 2.240 nm as the temperature increases. Meanwhile, from UV-Vis result, it can be seen that AZO thin film have a high transmittance percentage above 90% after wavelength 400 nm with band gap value of 3.3 eV. FESEM image show that the grain boundary of AZO decrease with both parameter (mole ratio and calcinations temperature). Both parameters do have effect on AZO thin film. EDX analysis shows that there are existence of zinc, oxide, and aluminum

Abrasive wear behaviour of conventional and large-particle tungsten carbide-based cermet coatings as a function of abrasive size and type

Abrasive wear behaviour of materials can be assessed using a wide variety of testing methods, and the relative performance of materials will tend to depend upon the testing procedure employed. In this work, two cermet type coatings have been examined, namely (i) a conventional tungsten carbide-cobalt thermally sprayed coating with a carbide size of between ∼0.3 – 5 μm and (ii) a tungsten carbide-nickel alloy weld overlay with large spherical carbides of the order of ∼50 – 140 μm in diameter (DuraStell). The wear behaviour of these two materials has been examined by the use of two abrasion tests, namely the micro-scale abrasion test using both silica and alumina abrasives (typically 2-10 μm in size), and the dry sand-rubber wheel test (ASTM G65), again with both silica and alumina abrasives (typically 180 – 300 μm in size). It was found that when the abrasive particles were of the same scale or larger than the mean free path between the hard phase particles, then the matrix phase was well protected by the hard phases. Testing (in both test types) with alumina abrasives resulted in wear of both the hard carbide phases and the matrix phases in both the thermally sprayed coating and the weld overlay, with the thermally sprayed coating exhibiting lower wear rates. The wear behaviour of the materials with the more industrially relevant silica abrasive was more complex; the thermally sprayed coating exhibited a lower wear rate than the weld overlay with the fine abrasive in the micro-scale abrasion test due to effective shielding of the matrix from abrasive action due to the fine reinforcement particle size. In contrast, with the coarser silica abrasive in the dry sand-rubber wheel test, the weld overlay with the large carbides was able to provide matrix protection with low rates of wear, whereas the thermally sprayed coating wore by fracture of the more brittle microstructure. These findings demonstrate the importance of selection of appropriate laboratory test procedures and abrasives to simulate behaviour of materials in service environments
