    Earthing systems acts as a significant part of the safety of the electric system. Under standard and failure situations, it should be necessary to be functioning efficiently in electrical system safety throughout all times. This project is to study the effect of Natural Enhancement Material (NEM) by using Fall of Potential Method to the eartihing resistivity. The NEM material used is Kenaf, Straw Rice ash and Palm Oil Residue Ashes. The measurement took part for 60 days. The purpose of this project is to compare the effect of the NEM as the additive material to the earthing system between three situations, Reference as bare soil, Kenaf with Straw Rice Ash and Kenaf with Palm Oil Residue Ashes. With two NEM material has been conducted, the analysis shown which the better material combing can improve the earth resistivity.

    Nowadays, demand for electricity is increasing every single day. This is due to the deep requirements in current economy. Generating electricity is an important element to ensuring a system operates in good condition and not being affected. At the same time, some problems have arisen as a phenomenon of transient stability. Hence, analysis needs to be done to control energy stability in rivalling current demand. Power system stability can be further divided into 3 sub-analysis starting with rotor angle stability which is the ability of synchronous machines of an interconnected power system to remain in synchronism after being subjected to a disturbance, voltage stability which is the ability of a power system to maintain steady voltages at all buses in the system after being subjected to a disturbance and also frequency stability which the ability of a power system to maintain steady frequency following a severe system disturbance resulting in a significant imbalance between generation and load. This analysis is used the IEEE Bus System 14 and analyzed using Power World Simulator (PWS) software. The variations in power angle, bus voltage and system frequency were studied with the help of three-phase balanced fault. Fast fault clearing times were analysed for a three-phase balanced fault in order to re-establish the stability of the system. Furthermore, impact of fault location on system was also computed to observe whether it affected the stability of the systems.

    This study investigates the effect of interactional justice (IJ) and organizational citizenship behaviour (OCB) on burnout (BO) among housemen in Malaysia Public Hospital. This study involve 15 urban hospital in Malaysia. Quantitative method was used in the study to analyse the questionnaire. The questionnaire will distribute to the 800 housemen in 15 urban public hospital in Malaysia. The questionnaire will analyze by using PLS-SEM statistical tool. From the analyze the hypothesis are accepted and significant. The IJ and OCB can reduce the value of BO among housemen in public hospital. The information based on this study will be a valuable guide to the Ministry of Health (MoH) in and decrease the level of burnout among housemen in Malaysia. The hospital management also can use the information based on the study to upgrade the policy and standard operating procedure (SOP) towards the management of the housemen. Also, this study can be the basis to help the Malaysian housemen to identify the causes of burnout and improve their perspectives upon this issue. Not only that, knowing the dimensions of burnout and its causes can create a positive vibe in the medical environment, particularly among the ministry, hospital management, housemen, and patients.

    In Malaysia, the El-Nino phenomenon happen in 2016 was caused the used of home appliances increasing including air-conditioner, fan and air cooler which are used frequently compared to other appliances. This report presents prototype development System for Security and Temperature Control using Microcontroller Based with Smartphone Application. The system has beneficial to reduce human labour besides energy saving and designed for special purposes which can easily maintain the temperature in sorrounding home. The system used several sensors for input parts including LM35 for temperature sensor and Passive Infra-Red (PIR) sensor for motion detector. For security system, the Radio-frequency Identification (RFID) has been used as security input user identification. A microcontroller arduino uno type is used as the system brain in the process part. In outputs part, servo motor has been used as door application while Light-Emitting Diode (LED) and buzzer as indicators when RFID is in use. A smartphone application is implemented in the system which allows the user to control a device remotely including home appliances through Bluetooth module. All data will display in Liquid Crystal Display (LCD) as user reference.

    Design of controller for boost converter to regulate voltage output
    ( 2015)
    Aminudin Anuar
    Capacitor can be used as an energy storage element to supply small power in replacing a battery. The advantage of using capacitor is the charging time is much faster than charging a battery. But the disadvantage is that the capacitor voltage value is not constant to supply a load. From that, a dissertation project has been conducted to design a controller using boost converter to regulate the capacitor voltage output. The boost converter used to control the voltage level. The boost converter circuit is constructed with power switch MOSFET. To generate pulse width modulation (PWM) to the MOSFET, a PIC16F877 used to drive PWM at specific switching frequency. The output voltage will step up from input voltage and use to operate the load. In this project, the complete circuit is designed using Matlab Simulink software with a specific value of parameter components. The design parameter is simulated and implemented into hardware and tested to get the result. There are two experiment has been handled. The first is the measurement of voltage output capacitor when connecting with or without controller and second is the controller design is connected to a load. From the experiment, the output voltage capacitor for circuit without boost converter has the result proportionally to the voltage input and the effect of the load. The circuit with boost converter is maintained at 24V for every voltage input and also connected to various load.
