Improving questionnaire reliability using construct reliability for researches in educational technology
Mohd Shafie Rosli
This paper is exploring on maneuver to improve research instrument reliability in scientific research related to Educational Technology by analyzing the traditional Cronbach?s alpha reliability using SPSS software and the newer statistical tool, AMOS using Construct Reliability (CR) approach. Two sets of data were used as sample to perform the comparison. The first set of data is from a research involving Technology Enhanced Learning Environment. The second data are sampled from research in digital competency. Finding from this paper concluded that, conventional approach of using Cronbach?s alpha have lower reliability than the newer approach of using CR. Using Cronbach?s alpha show tendency toward measuring consistency instead of reliability. CR offer better definition of reliability and give a robust measurement of reliability in research. This paper had shed light into offering alternative approach to the commonly and widely uses of research reliability especially when it involves q.....

Improving novice students' computational thinking skills by problem-solving and metacognitive techniques
Nor Hasbiah Ubaidullah
Admittedly, the teaching and learning of programming courses in the computer science and information technology programs have been extremely challenging. Currently, most instructors depend on either the problem-solving technique or the metacognitive technique to help students develop a range of cognitive skills, including metacognitive skills, which are important in the development of a strong computational thinking skill required for 21st-century learning. Studies focusing on the practices of instructors in using both techniques are scarce, thus motivating the researchers to carry out this study. This study was based on a qualitative approach involving a case-study design in which five (5) male and five (5) female instructors were selected from 10 pre-university centers in Malaysia as the respondents and participants in an intervention program. The research instruments used were an interview checklist and intervention guidelines. As anticipated, the findings showed that the activities.....

Improvement of the ESA CCI land cover maps for water balance analysis in tropical regions: a case study in the Muda River Basin, Malaysia
Tan, Mou Leong
Study region: The Muda River Basin (MRB), Malaysia. Study Focus: This study proposed a framework to improve the European Space Agency Climate Change Initiative Land Cover (ESA CCI LC) products through the integration with the Annual Oil Palm Dataset (AOPD). The improved land use land cover (LULC) maps were then used to produce five LULC scenarios as input maps into the Soil and Water Assessment Tool (SWAT) model for analyzing the impact of LULC changes on water balance in the MRB. New hydrological insights for the region: The improved LULC maps have good performance in representing rubber and oil palm, with an overall accuracy up to 81 %. In addition, SWAT simulated monthly streamflow well for the MRB, with the highest R2 and NSE values of 0.84 and 0.86, respectively. During the 2001?2016 period, the MRB experienced an expansion of oil palm from 7.10%?17.36 %, a reduction of rubber from 34.93 % to 26.38 % and a slight decrease in forest from 54.23%?52.80 %. The urban expansion scenario.....

Improvement of corrosion resistance of tin coated on titanium alloy for biomedical application
Arman Shah Abdullah
This work aims to study the effect of mechanical treatment technique on titanium coated with PVD for the enhancement of corrosion resistance for the biomedical implant. First, substrates were coated with TiN via PVD then applied the mechanical treatment through ultrasonic vibration. Results show that all coated samples treated with ultrasonic vibration improve the surface of the coated sample and produce a compact coating as compared with a substrate coated without mechanical treatment. The corrosion test evaluated by Potentiodynamic polarization and Electrochemical Impedance Spectroscopy indicated that all coated samples treated with mechanical treatment showed high corrosion resistance as compared with the untreated sample. It can be concluded that mechanical treatment which is a simple technic can be used as an alternative to improve the corrosion resistance thus reduce the implant and manufacturing cost for biomedical applications. ?

Implementation strategy of primary health care in ovia communities
Mohamed Nor Azhari Azman
Primary health care is the essential health service provided at the grassroot level. Over the years the implementation of Primary Health Care (PHC) programmes in Edo state are bedeviled with associated challenges such as limited community participation, great communication gap that limit evaluation processes of PHC programme and slow pace collaboration among stakeholders. These challenges need to be averted through effective and people oriented strategies to ensure the implementation of primary health care. A descriptive research design with a population of the study comprised 1,024 primary health care stakeholders in Edo state. Multi-stage sampling technique was used to select 180 respondents for the study. The study found that intersectoral collaboration involving partnerships with community health agencies such as village health committees and ward health committees significantly influenced the implementation of PHC. Intersectoral collaboration, community mobilization strategy and c.....

Implementation of video modeling in the occupational therapy intervention process for children and adolescents with special needs: a scoping review
Kadar, Masne
This scoping review explores the implementation of video modeling (VM) by occupational therapists during the intervention process for children and adolescents with special needs. Four primary electronic databases were used to conduct the scoping review: PubMed, Scopus, CINAHL, and Proquest (Nursing and Allied Health). Research methodologies by Arksey and O?Malley were used as a framework to perform the review process. From the review, two themes emerged: (1) implementing VM by occupational therapists during the intervention process can successfully improve a client?s desired skills; (2) VM can be applied through several types of technologies. The findings support occupational therapists? use of VM during interventions to positively enhance and promote desired skills among children and adolescents with special needs. Also, it can be incorporated into technological devices to suit a client?s specific needs. ? 2021 Taylor & Francis Group, LLC...

Implementation of the AHP method to determine the priority of recharge areas in the Semarang City
Qudus, Nur
the selection of a certain region as an area for groundwater recharge requires priority on the development of a region. Groundwater recharge area has an important role in maintaining a clean water supply in an urban area.One of the impacts of the environmental damage is the damage to the potential for groundwater supplies. This environmental damage is caused by changes in land use, especially in areas of groundwater recharge, residential and industrial development as well as uncontrolled pumping of groundwater. If this happens for a long period, it can disrupt the hydrological cycle system which results in decreased quality and quantity of groundwater, flood, erosion and landslides, and seawater intrusion. Therefore, the selection of a certain region as an area for groundwater recharge requires priority on the development of a region. Groundwater recharge area has an important role in maintaining a clean water supply in an urban area. The urban area is an area that experiences rapid de.....

Impact of sandwiched strain periodic multilayer AlN/GaN on strain and crystalline quality of a-plane GaN
Anas Kamarundzaman
We demonstrated high-quality single crystalline a-plane undoped-gallium nitride grown on a nonpatterned r-plane sapphire substrate via metal?organic chemical vapor deposition. The effect of four different numbers of sandwiched strain-periodic AlN/GaN multilayers on the strain state, crystal quality, optical and electrical properties was investigated. Field emission scanning electron microscopy and atomic force microscopy showed that the surface morphology was improved upon insertion of 120 pairs of AlN/GaN thin layers with a root-mean-square roughness of 2.15�nm. On-axis X-ray ?-scan rocking curves showed enhanced crystalline quality: the full width at half maximum decreased from 1224 to 756 arcsec along the [0001] direction and from 2628 to 1360 arcsec along the [1?100] direction for a-GaN grown with 120 pairs of AlN/GaN compared to a-GaN without AlN/GaN pairs. Reciprocal space mapping showed that a-plane GaN with a high number of AlN/GaN pairs exhibits near-relaxation strain states.....

Impact of crystallinity towards the performance of semi-polar (11-22) GaN UV photodetector
Supangat, Azzuliani
Crystal engineered semi-polar (11?22) GaN-based UV photodetectors have been fabricated which exhibit two dissimilar photo-responses depending on the crystal quality. The higher crystal quality evaluated via x-ray rocking curve (XRC) exhibited remarkable narrow full width half maximum (FWHM) along [-1?123] and [1?100] of 0.11� (396 arcsec) and 0.28� (1008 arcsec), respectively. Integration of the high crystalline structure with the metal?semiconductor-metal type photodetector resulted in notably lower dark current of 4.6?A. The responsivity value is significantly enhanced from 117 mA/W to 325 mA/W with higher crystalline epilayer. The photo-response of the detector made with the enhanced crystal epilayer is measured to be as low as 170 ms with a recovery time of 241 ms by which is the fastest switching time ever reported in semi-polar (11?22) GaN metal?semiconductor-metal UV photodetector. ? 2020 Elsevier B.V...
