Psychological perspective on language learning : a behaviorist approach

Abstract

The issue being presented is the reliability of the field of psychology in particular the Behaviorist approach to language learning and it’s application to computer assisted instructions namely suitable computer programs. The ideas introduced by Ivan Pavlov, E.L.Thorndike and B.F.Skinner is the main focus and teachers are shown the importance of reinforcements that occur in a classroom. The next stage is to explore the application in the classroom and how teachers can exploit the aspects learnt in the way they behave to the students or how they control the students in their behavior. Many researches have been conducted in this field mainly by psychologist and educationist to show a systematic correlation between learning excellence and reinforcement. Finally, the education system needs to restructure itself as far as psychological aspects of the knowledge giver (teacher) and the knowledge taker (students) is concerned in order to ‘educate’ the masses...

Kualiti air fiziko-kimia di hulu lembangan Sungai Bernam

Husna Nabilah Hamidon

Abstract

Kajian ini bertujuan untuk mengenal pasti kualiti fiziko-kimia air di hulu lembangan Sungai Bernam kerana terdapat pembinaan kawasan perumahan yang baru dijalankan oleh pihak pemaju. Sampel air sungai di tiga stesen dicerap sebanyak seminggu sekali dari bulan Oktober 2019 sehingga Februari 2020. Kajian ini melibatkan parameter in-situ dan analisis makmal berdasarkan enam parameter iaitu oksigen terlarut (DO), pH, kehendak oksigen biokimia (BOD), keperluan oksigen kimia (COD), ammonia nitrogen (AN) dan pepejal terampai (SS). Data yang dicerap dianalisis dengan menggunakan analisis deskriptif. Sementara itu, analisis non-parametrik iaitu ujian Mann-Kendall digunakan untuk melihat trend kualiti air di stesen Pekan Tanjong Malim dari tahun 1993 hingga 2018. Data dianalisis dengan menggunakan Statistical Software for Excel (XLSTAT) 2020. Akhir sekali, kualiti fiziko-kimia air dikelaskan untuk mengenal pasti status kualiti air berdasarkan indeks kualiti air (IKA). Dapatan kajian b.....

Water quality of selected rivers in Behrang River catchment, Perak Malaysia

Husna Nabilah Hamidon

Abstract

Water quality is essential for human health, environment, agriculture and more aspects related to human lives. This study aimed to evaluate the water quality in selected four rivers around Behrang catchments, Perak, Malaysia. Sampling was carried out from November 2017 to January 2018 in five stations twice a week to identify changes in water body. The study was implemented using in-situ parameters and water samples from the rivers to be tested in laboratory. Physicochemical parameters include temperature, conductivity (CND), total dissolved solids (TDS), dissolved oxygen (DO), potential of hydrogen (pH), biochemical oxygen demand (BOD), chemical oxygen demand (COD), ammonia-nitrogen (NH3-N), and suspended solids (SS). The water quality was determined based on (INWQS), which categorises pollution levels from clean to contaminated in the order of Classes I, II, III, IV, and V. According to the land use, agricultural activity is dominant and main contributor to the water quality in Behra.....

Adsorption of Rhodamine b by Sulfocalix(4)Arene thin films for dye removal application

Farish Armani Hamidon

Abstract

This study investigates the potential of Sulfocalix[4]arene (SC[4]) thin film for the removal and molecular-level adsorption of Rhodamine B dye (RhB), focusing on its performance in extraction and adherence. SC[4] thin films with 5, 10, 15, and 20 layers were fabricated using the spin coating method and subsequently characterised for its optical and topographical properties. Optical characterisation using Ultraviolet-Visible Spectroscopy (UV-Vis) at wavelengths from 260 to 300 nm revealed a progressive increase in absorbance across layers, notably at 277 nm and 283 nm peaks. Topographical analysis was conducted using Atomic Force Microscopy (AFM) to determine thickness and surface roughness. Results indicated a linear correlation between film thickness and the number of layers, with measurements of 58.175 nm for 5 layers, 77.626 nm for 10 layers, 84.608 nm for 15 layers, and 94.806 nm for 20 layers. Surface roughness, quantified via root mean square roughness (Rq), was significantly in.....

A comprehensive study of 4-sulfocalix[4]arene thin films with atomic force microscopy: thickness and topographical analysis

Farish Armani Hamidon

Abstract

This study aims to characterise 4-Sulfocalix[4]arene (SC[4]) thin films using Atomic Force Microscopy (AFM) in analysing its thickness and surface morphology. Quartz substrates were cleaned using ultrasonic cleaning with an Elmasonic P70H. SC[4] thin films were then fabricated on a quartz surface using WS-400BZ-6NPP/A1/AR1 model spin coater from Laurel Technologies, producing thin films with 5, 10, 15, and 20 layers. Each thin film was characterised in the tapping mode of the AFM Park System NX-10. Scans were conducted on different film areas of different scales, and the data were analysed using XEI Data Processing and Analysis Software. Height measurements obtained via Line Profile analysis revealed a progressive increase in film thickness with the additional layers, demonstrating a significant linear relationship. AFM images showed precise 2D and 3D surface topography, indicating that the thin films became uneven and non-uniform with the addition of more layers. The findings demonstr.....
