An assessment of workplace skills acquired by students of vocational and technical education institutions.

This study was performed to identify the employability skills of technical students from the Industrial Training Institutes (ITI) and Indigenous People’s Trust Council (MARA) Skills Training Institutes (IKM) in Malaysia. The study sample consisted of 850 final year trainees of IKM and ITI. The sample was chosen by a random sampling procedure from a population of 2520 students from both institutions. Trainees’ employability skills were measured using a 40 item questionnaire adapted from the Secretary’s Commission on Achieving Necessary Skills (SCANS) report. In general, the majority of the trainees possessed a moderate level of employability skills (Mean= 3.88, S.D= .49). Their basic skills were at the moderate level (Mean= 3.83, S.D= .9); thinking skills (Mean= 3.73, S.D= .56); source skills (Mean= 3.83, S.D= .57); informational (Mean= 3.61, S.D= .76); interpersonal (Mean= 3.92, S.D= .57); technical and system skills (Mean= 3.81, S.D= .67); and self-qualities (Mean= 4.14, S.D= .55). There were no significant differences of employability skills between trainees from IKM and ITI in term of gender, work experience, and between courses

Spectrophotometric determination of benzoic acid based on inhibitive effect on tyrosinase enzyme

A simple method for detection of benzoic acid in food products has been developed based on inhibitive effect on tyrosinase enzyme. A mixture of tyrosinase, phenol and 3-methyl-2-benzothiazolinone hydrazone (MBTH) gave a maroon coloured solution which was bleached upon addition of benzoic acid. The wavelength at maximum absorbance was determined as 504 nm. The biosensor demonstrated optimum activity at pH 7. The relative standard deviation (RSD) of the reproducibility of this method was very good with RSD value of 1.91 %. The dynamic range of benzoic acid concentration was found to be between 50-700 ppm with the detection limit of 109 ppm. The kinetic parameters Michaelis-Menten constant (KM) and maximum absorbance (Absmax) in the absence and in the presence of benzoic acid were also evaluated. The kinetic analyses show that the inhibition of benzoic acid on the tyrosinase activity is reversible and competitive with an inhibition constant of 90.9 ppm. The proposed method was compared with HPLC and satisfactory agreement was achieved

A tapered fibre optics biosensor for histamine detection

Purpose: This paper aims to estimate the level of histamine in fish and fish products, as it is very important because of their implication in fish poisoning in humans; hence, ascertaining histamine levels in the aforementioned serves as a chemical index for spoilage. Design/methodology/approach: A technique was developed to immobilize an ordered multilayer of diamine oxidase (DAO) by means of chemical cross-linking on the biconical taper surface stepwisely alternating between chitosan, glutaraldehyde and the enzyme. A spectrophotometric signal results from horseradish peroxidase catalyzed reduction of H2O2, a secondary product of the oxidative deamination of histamine monitored at 450 nm. Findings: The biosensor showed a linear response range up to 1.5 mM, a good sensitivity of 0.64 mM-1 with detection and quantification limits towards histamine of 0.086 mM (15.8 ppm) and 0.204 mM (37.7 ppm) and a linear response range of 0-1.5 mM. It showed a response and recovery time of 14 sec and operational stability up to 40 repeated analyses without significant loss of sensitivity. Practical implications: The developed biosensor has a good potential for use in the quantitative determination of histamine in seafood. Originality/value: The paper described an outcome of an experimental work on tapered fibre optics (taper)-based biosensor coated with DAO embedded into a chitosan membrane to measure histamine
