    A confined space has a limited space for entry and exit but it is large enough for workers to enter and perform work inside. It is not designed for continuous occupancy because it can contribute atmospheric hazards accidents that threaten the worker safety and industry progress. In this work, we reported the testing an instrument to assist workers for atmosphere testing during pre-entry. An electronic nose (e-nose) using specific sensor arrays is the integration between hardware and software that able to sense different concentrations of gases in an air sample using pattern recognition techniques. The instrument utilizes multivariate statistical analysis which is Principal Component Analysis (PCA) for discriminate the different concentrations of gases and the Support Vector Machine (SVM) to classify the acquired data from the air sample. The instrument was successfully tested using diesel, gasoline, petrol and thinner. The results show that the instrument able to discriminate an air sample using PCA with total variation for 99.94%, while the classifier success rate for SVM indicates at 98.21% for train performance and 95.83% for test performance. This will contribute significantly to acquiring a new and alternative method of using the instrument for monitoring the atmospheric hazards in confined space to ensure the safety of workers during work progress in a confined space.

    This technical paper presents a developing portable blood analyzer for monitoring of human blood sample. Perseverance of blood sample in hospitals is important in order to obtain a great quality of blood and therefore it able to determining the human type of disease. This is a life-threatening early step in most medical applications fields such as diagnosis, treatment and medical research. The proposed system consists of three main parts. In the first part, the use of convenient and handy device to deal with the problem of incorrect temperature value and inadequate quantity of blood sample. Most of previous human hospitality services show a fail to handle and properly in time to take human blood sample for diagnosis in a schedule time frame such as not punctual in taking blood sample from a patient in three different times in one day. The consequences is that these blood sample are not in perfect quality for a correct estimation of the human disease towards a pathology unit. The proposed method is a device that uses infrared temperature system and non-contact blood sample quantity detection. In the second part is by combining those two approaches to single programmable electronic modules that are used to minimize the size of the portable device in the resulting techniques to improve the functionality. The third part is accomplished by using a modern technique to produce an interface to provide the value of human blood sample and shows it on display for monitoring purposes. The programmable coding has been test in several different types of sensors and physical part. The experimental results show that this method able to integrate both requirement of human blood sample perseverance with a contactless method towards a blood tube, providing the output value of quality characteristic in a display and making it well-suited for a convenient practical application system. The experimental results in real time applications shows the effectiveness, reliable and efficiency in the proposed approach which able to almost accurately detect and monitor the human blood sample with the ability to detect different types of people gender and blood type. The proposed coding system can be executed at more precise time scheduling which is better than real life human monitoring system.

    This research is used to crank start automotive vehicle. There are many different system used in order to start-up vehicles using electric starter, in the time of battery low-power or totally drained. The purpose of this research is to help the driver to get out of this difficulty. Nowadays there are many people that have experienced such a bad moment, where they are stranded at road side due to malfunction starter in their car because of battery problem. Most of the vehicle electric starter failure is because of battery corrosion or battery undercharged. The importance of this research is to solve this problem. Starter is a vital part of the vehicle, without it no automotive vehicles able to operate. These starters will rotate an internal-combustion engine to initiate the engine's operation under its own power. Starters also can be malfunction too due to corroded electrical connections or an undercharged battery. This system can be used to solve this problem. This system used human energy by using mechanical parts in order to produce electrical power. In order to produce electrical current, workforce will be applied by rotating the wheel that already linked by belt and from that rotations will trigger a magnetic force and it will produce an electrical current and supply it into battery.

    This paper presents about design, analyses development and fabrication of robotic arm for sorting multi-material. The major problem that urges the initiation of the project is the fact that manufacturing industry is growing at relatively faster rate. Most of the company produce high load robotic arm. Less company creates light weight, and affordable robotic arm. As the result, light weight and affordable robot is developing to cover this issue. Plastic material was used to construct the body of the robotic arm, and an optical sensor was implemented to provide basic recognition of object to be carried. The robotic arm used five servomotors for overall operation; four for its joints, and one for the gripping mechanism. The gripper was designed and fabricated using Perspex due to the light weight and high strength of the material. The operation of the robotic arm was governed by Basic Stamp programming sequence and the device was expected to differentiate material and other objects based on reflective theory, and perform subsequent operations afterwards. The SolidWorks was used to model the detail design of the robotic arm, and to simulate the motion of the device.
