- PublicationKnowledge and prevention practices of hand, foot and mouth disease (HFMD) among parents who visited Hospital Pakar Universiti Sains Malaysia (HPUSM)(2025-08)Hand, Foot and Mouth Disease (HFMD) is a highly contagious viral illness that primarily affects children. While typically mild, severe complications may arise without timely intervention. This cross-sectional study aimed to assess the level of knowledge and preventive practices regarding HFMD among parents who visited Hospital Pakar Universiti Sains Malaysia (HPUSM), and to examine the relationship between knowledge and preventive behaviour. A total of 191 parents participated using a validated, self-administered questionnaire adapted from previous studies. The instruments measured socio-demographic characteristics, knowledge of HFMD, and preventive practices. Responses were classified using Bloom’s cut-off points. Results showed that 52.8% of respondents had a high level of knowledge, 44.6% moderate, and 0.5% low. In terms of preventive practices, 87.2% reported good practices, 10.8% moderate, and none reported poor practices. Common measures included frequent handwashing, avoiding crowded areas during outbreaks, and cleaning toys and surfaces. However, some misconceptions persisted, particularly regarding modes of transmission and the severity of the disease. Pearson’s correlation analysis revealed a weak, positive but statistically insignificant relationship (r = 0.118, p = 0.103) between knowledge and preventive practices. This suggests that knowledge alone may not sufficiently influence behaviour, and that other factors such as risk perception and social norms may also play a critical role. Overall, the study indicates a generally high level of knowledge and good preventive practices among parents at HPUSM. Nonetheless, targeted health education initiatives remain necessary to address knowledge gaps and promote sustained hygiene practices to curb the transmission of HFMD
- PublicationAssessing knowledge and awareness of multiple sclerosis among adults attending Hospital Pakar Universiti Sains Malaysia (HPUSM) outpatient clinics(2025-08)Multiple sclerosis (MS) is a chronic, idiopathic autoimmune disease characterized by inflammation of the central nervous system, leading to demyelination and subsequent axonal degeneration, and typically affecting young adults (Calabresi, 2004). This study aimed to assess the level of knowledge and awareness of MS among adults attending the outpatient clinic at Hospital Pakar Universiti Sains Malaysia (HPUSM) and to determine whether there is any association between knowledge or awareness and selected socio-demographic factors. A cross-sectional study was conducted among 147 adult participants at HPUSM outpatient clinic using a validated self-administered questionnaire, the MS Knowledge Questionnaire (MSKQ-25) and awareness questionnaire. Data were analyzed using descriptive statistics and Chi-square tests to identify associations between knowledge and awareness levels and socio-demographic variables. The mean knowledge score was 7.88 ± 4.626 with 84.4% of participants demonstrating poor knowledge. The mean awareness score was 2.90 ± 1.98, and only 22.4% of participants had high awareness. There was a statistically significant association between source of information and awareness level (p = 0.018). However, no significant associations were found between knowledge and age (p = 0.363), gender (p = 0.076), or educational level (p = 0.119). In conclusion, the findings indicate a generally low level of knowledge and awareness about MS among the studied population
- PublicationKnowledge and attitude toward providing oral healthcare for older adults among degree nursing students at School Of Health Science, Universiti Sains Malaysia(2025-08)This study investigates the knowledge and attitudes of degree nursing students toward providing oral healthcare for older adults at the School of Health Science, Universiti Sains Malaysia. Oral healthcare is an important aspect of overall health, especially for older adults. However, this aspect is still underemphasised in nursing education. The objectives were to determine the levels of knowledge and attitude toward oral healthcare provision for older adults and to examine the correlation between these two factors among nursing students. A cross-sectional study was conducted using convenience sampling. A total of 107 degree nursing students participated in this study through a structured questionnaire distributed online. Data were collected through a structured questionnaire adapted from Bhagat et al. (2023), focusing on knowledge, attitude, experience in providing oral healthcare to older adults, and personal oral health behaviours. Analysis revealed a weak positive correlation (r = 0.017, p = 0.068) between students’ knowledge and attitude levels, indicating no statistically significant correlation. These findings indicate the need for specialised modules and practical training on oral healthcare in the nursing curriculum to enhance knowledge, positive attitudes, and holistic care for older adults
- PublicationKnowledge and attitude towards long acting- reversible contraceptive (LARC) among married women who attended the outpatient clinic at Hospital Pakar Universiti Sains Malaysia (HPUSM)(2025-08)Long-acting reversible contraceptives (LARC) are modern contraceptive methods known for their high effectiveness and long-term protection with minimal user intervention. This study aimed to assess the level of knowledge and attitude towards LARC among married women who attended the outpatient clinic at Hospital Pakar Universiti Sains Malaysia (HPUSM). A cross-sectional study was conducted at HPUSM from January to March 2025 involving 136 conveniently selected married women, using a self-administered questionnaire to assess their knowledge and attitude. The questionnaire included items on socio-demographic data, knowledge of LARC methods (such as IUCD and Implanon), and attitudes regarding their use. The findings showed that 32.4% of respondents had high knowledge, 39.7% moderate, and 27.9% low knowledge; while 30.1% had a positive attitude, 24.3% moderate, and 45.6% negative attitude toward LARC. The mean age of respondents was 35 years (SD = 7.89), ranging from 19 to 49 years. A significant association was found between knowledge and attitude levels (p < 0.001), and socio-demographic factors such as age, occupation, education, and parity were also significantly associated with knowledge and attitude (p < 0.05). In conclusion, although general awareness of LARC exists among married women at HPUSM, detailed knowledge and positive attitudes remain limited, highlighting the need for targeted educational interventions to improve informed contraceptive choices
- PublicationNutritive and physical quality analysis of black pepper dried with optimized-hybrid solar drying systems(2025-01)Black pepper holds significant commercial importance in Malaysia. Consumer preference is driven by its nutritional and physical properties. While open sun drying (OSD) is widely used in tropical countries by virtue of its cost effectiveness, it presents several limitations, including labour intensive, time consuming, weather dependency and contamination risks. Hybrid Solar Drying System (HSDS) have emerged as an alternative to address these limitations. Hence, this study aims to evaluate the efficiency of HSDS compared to OSD and assess the nutritional composition and physical quality of HSDS-dried black pepper relative to commercial black pepper. The efficiency of HSDS drying the black pepper was evaluated by plotting a moisture removal graph to analyse the equilibrium moisture content (EMC) in the curve. Nutritional composition (moisture, ash, protein, oil, crude fiber and carbohydrate (CHO)) of HSDS-dried and commercial samples were determined using standard methods. Physical properties including colour, density, geometric mean diameter, and sphericity, were also analyzed. Drying kinetics demonstrated that HSDS was more efficient than OSD in removing moisture from black pepper. Proximate analysis revealed significantly higher oil content (6.23%) and lower ash content (3.08%) in HSDS-dried pepper compared to commercial pepper (4.71% and 3.70% respectively, p < 0.05). No significant differences were observed in moisture, protein, crude fiber, carbohydrate, density, geometric mean diameter, sphericity and a* value between HSDS-dried and commercial black pepper. Significant differences were observed in L* and b* values, indicating that HSDS-dried pepper exhibited a darker colour and a bluish hue compared to commercial black pepper which increase the market value. dE*ab value of 4.50 represented significant colour difference between HSDS-dried black pepper and commercial black pepper. In conclusion, these outcomes highlight the effectiveness of Black pepper holds significant commercial importance in Malaysia.

- PublicationSurface roughness analysis of co2 laser cutting of 304-stainless steel(2008-04-01)In this project, top, bottom and average surface have been investigated repetitively. Samples of stainless steel-304 were cut on a CO2 laser cutting system and the combined effects of power cutting speed and gas pressure on surface roughness and striation pattern have been studied. Design of Experiment (DOE) method will be used to understand the effect of various laser processing parameters changes on the surface finish. Analysis of Variance (ANOVA) was used to determine the significant factor and the percentage of contribution that affect the quality of surface roughness. For the range of operation conditions tested, it was observed that cutting speed had a major effect on surface finishing which increase the surface roughness of the 5mm stainless steel, while power affects were secondary. Low feed rates gave good surface roughness and low striation. Taguchi method was used to determine the optimum parameter to produce minimum surface roughness on 5mm thickness stainless steel- 304 by COs laser cutting.
- PublicationIntegration Of Sodium Alginate With Bacillus Subtilis As Microbial Composite For Fertilizer Coating Towards Green Agriculture(2022-06)Coating is a protective material that is applied to an object's surface such as fertilizer for various purposes. In this research, microbial composite film was fabricated by integrating sodium alginate with different mass of Bacillus subtilis. The films were tested on its physical, mechanical, chemical, and microbial properties. Then, study was conducted to improve the conductivity, moisture content and added micronutrient of microbial composite films for plants as supplement. Subsequently, organic goat manures as fertilizers were coated with different layers of microbial composite films coating via different drying techniques. Next, plant growth analysis and soil nutrients analysis were conducted by applying fertilizers of no coating, sodium alginate coating, and microbial composite coating (1-layer coating and 2-layer coating) to the plants to see its effect on the nutrients transfer. Furthermore, mathematical modelling was developed for soil nutrients analysis. It is found that 0.5 g bacterial cell mass from log phase had the most significant effect on the properties of the films. Then, by mixing microbial composite solution with 40 ppm copper ions and 1% glycerol render the highest conductivity to the films which is helpful in plant growth. It is also found that both 30-minutes drying and 24-hour drying technique did not give significant difference on the thickness of films and hence, 30-minutes drying technique was chosen as it saved time and cost in the process.

- PublicationEffect of membrane selectivity and configuration on purity and recovery of hydrogen from syngas(2021-01-01)In this thesis, simulation of a membrane gas separation system for purification of hydrogen from syngas has been discussed. The simulation was done to study the effects of membrane selectivity, flow configuration, stage cut and feed pressure on the purity and recovery of hydrogen from syngas. In order to model the membrane, a complete mixing model was applied to study these effects. The mathematical modelling involved in the simulation was done in Mathcad and the results were analysed using the analysis of variance (ANOVA) under the Response Surface Methodology (RSM) method. In order to produce high purity hydrogen that is accepted as commercial industrial grade hydrogen, we studied two types of flow configuration models. Configuration 1 involves a carbon dioxide permeable membrane while configuration 2 model involves a hydrogen permeable membrane. As a result, it is noticed that in the first configuration, at the stage cut of 0.2, feed pressure of 5 bar and CO2/H2 selectivity of 1500, the highest purity of hydrogen at 52.24% and recovery of 59.58% at the permeate stream is achieved. Meanwhile in the retentate stream, the purity and recovery of carbon dioxide achieved is 52.21% and 55.53% respectively. The second configuration is when a hydrogen permeable membrane is applied. This configuration results in the highest possible purity of hydrogen of 100% with recovery of 32.52% and carbon dioxide purity and recovery at 27.35% and 90.42% respectively, at stage cut of 0.2, feed pressure of 25 bar and H2/CO2 selectivity of 500.
