Measurement of Riverbank Erosion Rates of Pusu River Using Erosion Pins Method
Riverbank erosion is a major concern in all parts of the world due to its extensive impacts geomorphologically and economically. This study aims to quantify the rates of riverbank erosion of Pusu River using erosion pins method. Two sections of the river were selected namely site A and site B where site A is a straight section while site B is situated on the outside bend. 21 pins were installed at each site in a grid pattern. Measurement of erosion pins exposure were taken from February 2019 to April 2019. Field observation were made to identify the possible factors influencing the bank erosion. The average rates of bank erosion ranged between 0.05 cm/day to 0.21 cm/day at site A and 0.09 cm/day to 0.51 cm/day at site B. Bank failure occurred at site B towards the end of measurement period due to high flow after heavy rainfall event. Field observations suggest that rates of riverbank erosion were influenced by several factors such as the flow velocity and vegetative cover of the bank
Knowledge of Hepatitis B among undergraduate students in Universiti Teknologi MARA (UiTM) Selangor, Puncak Alam Campus / Nurul Atika Abu Bakar, Wan Nur Azrina Wan Mohd Zaid and Nur 'Aqilah Md Salleh
Background: Hepatitis is an inflammation of the liver, most generally brought on by a viral infection. In Malaysia, as indicated by Ministry of Health, there have been 5% of Malaysians infected with hepatitis B. Inadequate knowledge regarding Hepatitis B Virus (HBV) may put our teenagers at risk of the infection. Objective: This study was carried out to evaluate the knowledge of Hepatitis B among undergraduate students at Universiti Teknologi MARA (UiTM) Selangor, Puncak Alam Campus. Methods: A cross sectional study design was conducted using a survey questionnaire and was distributed to 367 undergraduate students at Universiti Teknologi MARA (UiTM) Selangor, Puncak Alam Campus. Result: The findings show that there is no statistically difference between knowledge of hepatitis B with demographic characteristics which are age, gender, ethnicity, faculty of study and years of study (p>0.05). About 66.3% of the participants do not know about Hepatitis B. Conclusion: As a conclusion, knowledge about Hepatitis B among undergraduate students was poor. There is no significance difference between knowledge of Hepatitis B and selected socio demographic data such as gender, age, faculty, and years of education
