Effect of pine fiber on concrete compressive and flexural strength
There are having been many efforts made to increase the capacity and strength in concrete technology. The use of natural fibers in concrete technology is one of the techniques used to achieve these objectives. The use of natural fibers as an additive in concrete is not widespread and not yet found a place in the industry. This research was carried out to establish the effects of pine fiber addition on concrete compressive and flexural strength. In this study, a total of 36 cubes (150mm x 150mm x 150 mm) and 12 small beams (100mm x 100mm x 500 mm) were prepared according to three types of mixture proportion and all these samples were cured in water curing for 7 days, 14 days and 35 days.
The three types of concrete mixture used in this research were concrete containing 0.1% pine fiber, 0.2% pine fiber and 0.3% pine fiber and plain concrete as control sample. The test results showed that the 0.1% pine fiber content is the optimum percentage of pine fiber additional. Even though the compressive strength result does not show the satisfied result, but the flexural strength of concrete is increased for 0.1% pine fiber. However, the strength of concrete does not increase with increasing of fiber content. The results show a good sign for further investigation to increase the flexural strength of concrete in presence of pine fiber as additive

DEVELOPEMENT OF WIRELESS SENSOR NETWORK FOR LANDSLIDE EARLY WARNING SYSTEM
Landslide is a massive catastrophe occurring all around the world and causing thousand of fatalities throughout the year. It is also ranked as second disaster in the level of destructiveness. The awareness on landslide issue has rise since 1960s, somehow there are still lack of technology developed to mitigate the risk of landslide occurrence. The existed technologies produced are highly sophisticated plus expensive. The campaign introduce by the local authority also did not enough to enhance awareness to prepare, and to reduce the impact of landslide. To solve this, this project will develop a wireless network system (WSN) for landslide early warning system which will alert the possibilities of landslide occurrence for further action and mitigation. Several sensors will be chosen to measure monitor the significant factors which possibly induce landslide. The effectiveness and robustness of the system will also be evaluated throughout the project via slope model and data acquisition in Moteview software
Development and fabricatin of production mechanism for small and medium animal feed production plant
Livestock production levels are currently unable to meet market demand. This is because the method used to produce livestock feeds is unproductive and efficient, beside lack of technology to process livestock feed. Therefore, some improvements should be made to ensure the sustainability, speed, and quality of feed stuffs with the complete specifications. Normally, livestock production process involves the following process processes which are crushing of raw materials, drying of raw materials that have been crushed, blending of feedstuffs with certain additives, and production of the products either in the form of pellets or pads. The main objective were to develop and fabricate the improvement component in processing the animal feed, increase the production rate and increase the chef life of the animal feed. So, towards the steps to improve the livestock production, industry A was selected the design 1 for their fabrication. The components contained in design 1 are the feeder machine, roller conveyor, weight balance, and packaging system. For feeder machines, several simulated has been tested to identify the stress and strength of the feeder machine in the real situation. After feeder machine modifications have been passed all the simulation tests, an agronomic features has been applied to the design, in addition to help solving the problem of agronomic conditions to the workers. After fabricated, the feed processing machine is tested to determine the extent to which the productivity and efficiency of the food feed can be improved. With the improvement toward the machine compared to existing, the production rate of the industry shows double increment from its original state. For the packing system, to ensure that the feed product can last a long time, the plastic that should be used is a plastic with thickness of 0.8mm, and the air contained in the plastic should be removed by using industrial vacuum. With this method the livestock feed will be long lasting
The association of nutritional status and perceived on disease among Auxiliary Police in UiTM Selangor, Malaysia / Muhammad Syafiq Zainol
A cross-sectional study was done in Universiti Teknologi MARA (UiTM) Selangor campus in order to assess the degree of perceived on disease among auxiliary police. The campuses that included in this study are UiTM Shah Alam, UiTM Puncak Alam, UiTM Puncak Perdana and UiTM Sungai Buloh. Objective of the study was to determine the association of nutritional status and perceived on disease among auxiliary police aged 18 to 65 years old in UiTM Selangor. Auxiliary police (n=122) were recruited and answered questionnaire in a booklet (hardcopy) form. The questioQJ1aire consist of demographics criteria including age, gender, academic level and income. Another part of the questionnaire was used to measure the perceived on disease among respondents including their behavioural and cue to action. Nutritional assessment are done consisting of anthropometric assessment and dietary assessment. Height and weight were measured in order to calculate body mass index (BMI). Dietary assessment is done by two days 24 hours diet recall (24-HDR) via face to face interview and analysed using Nutritionist Pro Software. 42 out of 122 respondents are criterion has high level of perceived on disease (34.4%) and the remainder 80 persons have low level of perceived on disease (65.6%). Results show that there are association between academic levels and perceived on disease among respondents (p=0.042). However, there are no association between age, gender and income with perceived on disease. Majority of auxiliary police in UiTM Selangor are overweight (n=51). Result shows that there are significant association between BMI and level of perceived on disease among respondents (p <0.05). However, there are no significant correlation between perceived on disease and dietary intake. Perceived on disease had been identified significant to behavior of reading nutrient labelling, searching health information through internet, mass media and consultation with professional health care. The findings from this study showed that level of perceived on disease among auxiliary police in UiTM Selangor are low and if they continue being unconcern, it will lead them to get disease in future
BACKEND DESIGN OF WIDEBAND LOW NOISE AMPLIFIER USING 130 NM RF CMOS TECHNOLOGY
Low Noise Amplifier (LNA) is widely applied nowadays for amplify very weak signals usually captured by antenna with reduced noise due to the gain of the LNA. Thus the main concern in this paper is in designing an LNA for ultra-wideband which cover frequency ranging from 3.1 GHz to 10.6 GHz. The design of the circuit is implemented using the 130 nm complementary metal-oxide semiconductor (CMOS) technology. Comparative studies have been done between inductive degeneration and common gate configuration with special consideration in terms of the corresponding noise figure
Experimental Works and Analysis to Determine the Degradation of Permanent Magnet Force under Cyclic Magnetic Field
Permanent magnet is widely used in today’s application such motors we used in car or generator in power stations. Materials commonly used are neodymium, alnico, and also soft ferrites. Its unique ability to retain its magnet force for such a long time is one of the attributes it excels in. However, loss of magnet’s strength or demagnetization can bring major impact in applications. External field or electric current is one of the method where a magnet can be magnetized and demagnetized by altering the number of domains of electrons which the mechanism of magnetism is present. Permanent magnet – permanent magnet interactions in cyclic motion resembles what happen in both motor and generators. Their magnetic strength is indeed all acting differently before, during and after the application to be specific, in cyclic motion. Hence, further research must be done followed by in-depth analysis to know how these magnets would react under cyclic motion
The Study of Flow Dynamics in Long Pipeline for the Transport of Carbon Dioxide (CO2)
Carbon dioxide (CO2) capture and storage (CCS) is usually considered as a chain consisting three separate elements; capture, transport and storage of the CO2. The capture and the storage are the two most studied parts of the CCS chain; however, the transport also gives the important roles in this system. For this study, the title of the project is to study the dynamics of the flow in the long pipeline for the transport of CO2.
The dynamics flow of the CO2 transport in a long pipeline was studied and analyzed. At first, before the study is carried out, the author thinks of the uncertainties that will arise in the transport of CO2. Some of the uncertainties that might occur are the effect of the flow, the pressure drop and the changes of the temperature but for this research, the author will do the study of the effect of the flow and the changes in the velocity and the pressure in long pipeline of the CO2 transport.
For the completion of this study, the author used two main methods which is using the research methodology and construction of the pipeline model using the Computational Fluid Dynamics (CFD) software. The research is carried out for the project’s concept understanding. The research had been done by reading the technical articles, and the previous related research from various author. Later the model is constructed using the CFD software.
As expected, for a very long and open ended pipeline, the pressure will drop as the length of the pipeline increases. Besides that the bending angle of the pipe also give impact to the flow of the CO2; the greater the bending angle of the pipeline, the higher the CO2 flow pressure will loss. In addition, in the bending pipeline, there will be a back flow occurred to the CO2 flo
Innovative Design of a Ball Injection Device for a Rapid Kill of Offshore Blowout Wells
This project makes an innovative design of ball injection device for a well blowout response system. Blowout is an uncontrolled flow of gas, oil or other formation fluids into the atmosphere or another zone. If this flow of hydrocarbons is not stopped in time, the hydrocarbon can ignite into a deadly firestorm call blowout. Because of the immense cost and danger associated with oil well blowouts, the well control industry resolves around the prevention and avoidance of blowouts. Unfortunately, well blowout still occurred such as Montara gas well blowout in 2009, Macondo well blowout in 2010 and recently in 2013, a blowout in Gulf of Mexico
The potential of sugarcane bagasse as antibacterial agent / Muhammad Syafiq Kamaruzaman
Sugarcane (Saccharum officinarum) is one of main agricultural resources that used by various industries. It is the important raw material in production of sugar and healthy drinks for people. From the industry, a lot of leftover called sugarcane bagasse been produced in a bulk every day. For every metric tonnes of sugarcane, it can produce 270 kg of sugarcane bagasse. Improper treatment of bagasse from agricultural and industrial sector can contaminates land, water and air. The accumulation of excess baggage can bring a waste problem for the sugar industry. This study is aim to determine the potential antibacterial activity of sugarcane bagasse and to compare antibacterial activity on different concentration. The sample was extracted by using methanol extraction method. Four series of sample concentration were used, 100%, 75%, 50% and 25%. Antibacterial effects of the extract were tested on Gram positive and Gram negative bacteria. The sample was tested with Gram positive bacteria (Bacillus subtilis and Staphylococcus aureus) and Gram negative bacteria (Escherichia coli and Salmonella sp.). On both Gram positive and Gram negative bacteria, the result shows that sugarcane bagasse has the potential to be antibacterial agent and the best concentration to inhibit Gram positive and Gram negative bacteria are 100 %, 75% and 50% with the exception of Salmonella sp. where it can be inhibition zone presence at all concentration
