Floods are a natural phenomenon that frequently occur in Malaysia. Flooding will cause water to become cloudy or turbid. In this situation, the supply of clean drinking water is the most affected component. Therefore, many researchers have designed a water filter system to overcome these problems. One of them is used chemical as purifying agen, or known as coaguland and flocculation process. In this...
Based on numerical analysis, we determine the ideal mix ratio of polyol-isocyanate content that influence the strength characteristic of polyurethane foam subjected to axial loadings. This paper focuses on compressive strength characteristics and provides the solution for ideal mix ratios of polyurethane foam. Fourteen (14) mix ratios are investigated in the numerical analyses; i.e. 1:0.59, 1:0.67,...
This paper presents the comparison of the MPC and PID control in compact hydro distillation process. Both of PID controllers and MPC undergone the performances of controller tests such as set point, set point change and load disturbances. The comparative performances of MPC and PID controllers (PIDCC and PIDZN) were evaluated and analysed based on transient responses performance and also in term of...
This paper presents on the design and development of infrared turbidity sensor for Aluminium Sulfate coagulant process. The electronic turbidity sensor operates based on the scattered light and absorption intensity with results to light scattering in solids and liquids. Natural environment is applied to this sensor to get the actual behavior of the water sample with NTU reading that is approximately...
Electro Pneumatic Trainer for educational applications is developed as supporting tools towards the existing typical teaching and learning process. The main objective is to improve the learning outcome towards student's cognitive knowledge and practical skill where the existing teaching and learning for electro pneumatic courses conducted in the classroom without emphasizing on simulation and complex...
This paper focuses on the design and development of a low cost nephelometric turbidity sensor for the continuity of domestic monitoring of water quality. The electronic turbidity sensor operates based on the scattered light intensity with regards to light scattering in solids and liquids. The electronic turbidity sensor used Light Emitting Diode (LED) as light transmitter, Light Dependent Resistor...
Floods are a natural phenomenon that occur frequently. However, the flood could turn into disasters which causing widespread damage, health problems and deaths. Consequently, these phenomena affect the ecosystems and habitats. The source of drinking water is the most affected component due to floods. Many researchers have designed the methods to purify the turbidity of water. In this study, the water...
Multiple Outputs Programmable Integrated Circuits (MOPICs) trainer for educational applications is fabricated based on unsatisfactory usage of PIC simulation which is not able to achieve the learning outcome especially in enhancing leaner's hands-on skill through circuit designing, connection and trouble shooting. Current PIC programming is done through computer simulation, cause the leaners facing...
Multiple input/output Programmable Logic Controller (PLC) module for educational purposes is fabricated because of current PLC Kit that was unable to enhance learners theoretical understanding and hands-on skill especially for programming, wiring, design of circuit and problem solving. The available PLC Kit comes with a casing which learners struggling in comprehend the theoretical knowledge, cabling...
This paper presents a review on significant parameters and techniques in water quality assessments used for drinking, domestic purposes and recreational purposes. To ensure water in good quality there are several parameters that have to be considered. Water quality index (WQI) is one of the most effective tools to an attempt to ascertain the water quality. There are many techniques on water quality...
