The residual soil is one of the major soils in the peninsular region of Malaysia. Because of this, engineering activities can employ this kind of residual soil in the building industry, such as retaining walls and high-rise building. Yet, because it is structurally complicated and has substantial weathering in most locations, the residual soil often brings in heterogeneities, which can lead to the failure of a structure. Finding the value of the shear strength parameters as a geotechnical properties is the key to solving this problem, which may be done here. After the soil samples had been compacted, they were put through a series triaxial tests, namely Consolidated Drained (CD) and Consolidated Undrained (CU) tests. A total of eight soil samples, four for each test were used for this study. As a consequence of the tests that have been carried out, the value of the cohesion parameter, c', as recorded by the CD test is greater than that recorded by the CU test. On the other hand, the value of the friction angle, ϕ ', as recorded by the CU test is greater than that recorded by the CD test. In the meantime, with regard to the stress-strain behaviour, the brittle failure pattern was seen in each and every sample that was put through the CD test. The pattern that was seen in the results of the CU test was also seen in the results of the CD test. The output of this study makes it abundantly evident that the maximum values for pore water pressure, lateral stress, and axial strain would be significantly increased if the effective confining stress that was applied to the sample was increased to a higher value.
It is a fact that windstorm is a natural disaster that can create enormous damages. Thus, the article aims to serve as a guideline in establishing the damages scale as the supporting tool in the windstorm disaster management. The purpose of the scale is to mitigate impacts of windstorm via early warning system, so that local authorities and public at the affected area are able to know the worst-case scenario if windstorm occurred and could make early preparation in minimising the impacts. The damage scale is established based on the current damage criteria as an early warning of windstorm occurrences was adopted from the damages scale which was established outside Malaysia. On the other hand, there is no damages scale originally established in the country. In order to establish this supporting tool, 51 windstorm occurrences in year 2012 to 2016 from 6 districts in Peninsular Malaysia were selected as a study case and 246 damages were assessed. Besides windstorm damages, gust speed, wind direction, rainfall and radar images as raw data, the study also acquires local conditions wind multiplier map coordinated with meteorological station and overlaid with wind direction map at the study area as well. All the damage locations for each windstorm occurrence will be coordinated in the local conditions wind multiplier map. However, the damages which located underneath the same convective cluster with meteorological station, in position with wind direction and gust speed greater than hazard threshold only will be determined its associated intensity. The scale listed each potential damage according to categories either building, property, or tree. The gust speeds at 1-minute in the scale are between 9.0 m/s to 19.3 m/s. From the study, damages scale has similar hierarchy of level damages with existing damages scale but much lower intensity.
KNOW YOU APP' was developed for the public to properly identify individuals. An individual in any organization can be identified by simply typing the organization and the individual's name; consequently, the detailed biodata and the photo of that individual will be displayed. Additional, this app include the recording of meetings so that in the future when they meet again, these records can provide information like when, where and why they met before. 30 respondents were selected from among the UiTM Pahang staff to provide feedback as users and by using SPSS analysis, a very positive feedback was found with 95% respondents gave a mean score of 4.0 to 5.0 to show the effectiveness level of this mobile application. © 2020MySE, FSPU, UiTM Perak, All rights reserved
Studies on soil erodibility in Malaysia were critically reviewed. Soil erodibility is the only factor of Universal Soil Loss Equation (USLE), which requires laboratory work and analysis complexity to estimate soil loss. Therefore, the main objective is to review soil erodibility studies to enhance understanding of Malaysia’s soil erosion impacts. These studies were summarized in their application, purpose, value, utilization method/approach, and study location. On the other hand, a summarization of what, why, where, and how the soil erodibility was used was analyzed. Therefore, the importance of soil erodibility as input for environmental management and conservation practices can be addressed. For a large-scale area, the soil erodibility factor will be analyzed as one of the USLE variables in estimating the erosion rate. As for a small-scale area, this factor is an adaption of the ROM Scale, which use to identify the slopes or riverbanks prone to landslides induced by erosion. However, the determination of this factor requires extensive artistry, time, and cost. These would be an obstacle to the holistic assessment of soil erosion impacts since only a little soil sampling will be analyzed. Therefore, the simplified version for the determination of soil erodibility without any requirement of laboratory works will be an extra mile, especially for an area that does not have any information on soil series.
