2024-11-06T12:28:39+08:00

Abstract: This study was carried out to identify the potential use of industrial waste known as “concrete slurry” intended for soil stabilization for road subgrade layers. Road soil sedimentation can be caused by various factors including heavy rain, construction of new infrastructure, excessive vehicle load, changes in soil properties and others. To overcome this problem, soil stabilization needs to be implemented during the construction process to increase the bearing capacity. Industrial waste such as “concrete slurry” can potentially be used in the soil stabilization process due to its properties that are similar as cement. This industrial waste was obtained from Hume Concrete Sdn. Bhd. Construction factory in Semambu, Kuantan. In order to study the potential of the waste, a total of six samples were prepared at the mixture rate of 0%, 8%, 16%, 24%, 32%, and 40% to be tested on the soil sample. The tests involved were compaction tests, sieve analysis tests, Atterberg limit tests and California Bearing Ratio (CBR) tests. The sample which has been compacted in the mould, is preserved for five days before the CBR test was carried out. Through analysis, it was found that the soil sample used in this study was of good grade with a high plasticity rate. Through the CBR test, it was found that the concrete slurry waste mixture of 32% showed the highest bearing ratio of 69% compared to the control sample of 12.5%. The total increase in soil strength was 81.88%. This shows that the use of this industrial waste can increase the strength of the soil bearing during the stabilization process and has the potential to be used as a stabilizing agent instead of cement or lime.

Determinants of Home Ownership Among the Urbanites in Melaka

2024-06-30T17:35:48+08:00

Over the past few years, the real estate market has been unbalanced in terms of supply and demand when supply exceeds demand, especially in urban areas. Although there is a high demand for affordable housing, the issue of house dumping is still a public debate. The difficulty of owning a house has always been a public issue debated by the government and the private sector in finding a solution for all stakeholders. With the current economic situation, buying a house is almost impossible due to the drastic increase in house prices in urban areas. In reality, urban communities need affordable housing to overcome the problem of renting a house, where the cost of renting is increasing. This study aims to identify whether factors such as market price, socio-economics, and community well-being affect home ownership, especially in Melaka urban areas. Data and information were obtained from house renters in some selected housing estates. The data collected from questionnaires was analysed using Statistical Package for Social Science (SPSS) 23 and Microsoft Excel software. The regression analysis method was employed for this study. The study results found that the increase in house prices affects the residents' ownership in the city, even though the demand for houses is always there. Design factors, types, and comfortable spaces are still the choices of today's home buyers. Socio-economic development factors also affect the demand of urban communities that choose housing estates near the city because of easy access, available infrastructure, and stunning green surroundings. The community well-being factor is a determining factor in the urban community's choice of a community-friendly environment and guaranteed security as one of the factors of home ownership in the future. In general, this study also helps housing developers study marketing strategies by considering the current needs of urban communities, such as market prices, socio-economic development, and a community-friendly housing environment. This study suggests that the government should make more efforts to increase homeownership in the urban community by providing quality housing and creating a united society along with development.

Implementation of Livewire Software in Output Waveform Analysis for Rectifier Circuit

2024-06-28T16:38:46+08:00

A diode performs a vital job as a rectifier, which changes alternating current (AC) into direct current (DC). Both half-wave and full-wave rectifier circuits in electronics can use diodes. Rectifiers are fundamental in electronics because many devices, such as computers, smartphones, and power supplies, require DC power. They ensure that the electrical current flows in a single direction, which is necessary for the proper functioning of these devices. The choice of rectifier type depends on the application's specific requirements, including the desired output voltage and current. The output voltage waveform can be analysed through an oscilloscope in the laboratory for education purposes. Instead of using an oscilloscope in the lab, we can also analyze output waveforms using electrical schematic software. In this study, the virtual oscilloscope offered by Livewire software's schematic simulation application will investigate the output signal from a half-wave and full-wave rectifier circuit. In conclusion, the waveform output from the rectifier circuit can be analyzed from livewire software successfully. Through the analysis obtained, we can determine the formation of each cycle for the output voltage rectifier for both half-wave and full-wave. It demonstrates how Livewire's virtual experiments can be utilized as a substitute for practical activities when learning online. Based on the Livewire simulation result, the halfwave rectifier's output only appears during the positive half cycle; meanwhile, the fullwave rectifier’s output of both half cycles appeared according to the input voltage.

The problem concerning key storage at Politeknik Tun Syed Nasir Syed Ismail (PTSN) systems is a lack of systematic administration, leading to uncontrolled and insecure essential management procedures. Consequently, the objective is to create an intelligent key tracking system (SKTS) utilizing radio frequency identification (RFID) and Arduino Mega to establish a secure and properly organized key storage system with efficient data management. This project introduces the monitoring system with automated and real-time data collection. SKTS design uses an Arduino Mega 2560 microcontroller and an ESP8266 Node MCU Wi-Fi module that sends data over the cloud. The project also utilizes the Telegram chat application bot to notify and monitor the keys' retrieval and return. It is also equipped with an RFID reader as a sensor. As the authorized user, once the RFID card is swept, type the selection key number; the solenoid lock for the selected key will open, and the key is free to be picked. The liquid crystal display (LCD) will show the authorized user data and selected room number. A signal will send the information to the Telegram application through a mobile phone to notify the other authorized user. This project successfully achieves its objective by utilizing the Telegram application to notify critical users and authorized individuals when keys are returned. These real-time notifications are visible to all registered group members on the Telegram application. The Likert Scale, which has two points, is established by utilizing data responses from the rubrics form, with evaluators consisting of industrial designers and researchers. The results are subsequently synthesized using qualitative percentages. The responses to the item provided via the rubric assessment form show that the SKTS meets the design, ideal, and functional aspects.

UV LED Printing Device for PCB Fabrication

2024-11-08T17:07:11+08:00

Photolithography is commonly used to fabricate printed circuit boards (PCBs) in micromanufacturing. It involves UV exposure to pattern portions of a thin film of a substrate before a geometric design is transferred from a photo mask to a light-sensitive substance (photoresist) on the substrate using light. Conventionally, metal halide lamps and UV fluorescent bulbs make up most of the exposure systems during photolithography. However, both systems are highly costly in educational establishments and consume high electrical energy. Moreover, they also have too broad UV radiation and are not appropriate for the sizes of PCBs that need to be mounted on the apparatus. Hence, this innovation aims to create a low-cost, portable UV exposure system that works well in educational settings by utilizing LED illumination technology. In order to manage time, relay, and LCD, these UV LED exposures were built using a combined LED circuit with a controller board. With a dimension of 120 mm by 190 mm and 3 mm LEDs, the UV LED circuit generates a wavelength of 400 to 405 mm for the UV exposure system. Due to its powerful and flexible design capabilities, LED lighting may be integrated in any shape to create highly efficient illumination. The testing result shows that LED lights have higher application efficiency due to its ability to concentrate light in one area. Therefore, well-designed LED illumination systems may deliver light to the intended spot more effectively. They also brighten up instantly when powered on and can be turned on and off repeatedly. This research has highlighted the advantages of LEDs for infrastructure projects, such as exposure systems, which could be further developed for future technology.

The Smart LPG Regulator is designed to oversee the regulation of pressurized steel gas cylinders in residential households. The primary goal of this project is to prevent the potential risks associated with LPG gas leaks, including the loss of life, injuries, and health concerns. The system is equipped to identify gas leaks and issue auditory and visual alerts through a buzzer, a display, and a servo motor, which promptly closes the gas cylinder regulator to terminate the gas supply. The LPG Gas Detector (MQ6) is a suitable sensor with high sensitivity to Liquid Petroleum Gas (LPG), including propane, proficient, isobutene, and natural gas. It is also capable of detecting easily flammable gases, mainly methane. Data collected by the MQ6 sensor is processed by the Atmega 328P microcontroller and presented through the output components. The LCD screen will display 'GAS LEAK,' the buzzer will sound an alarm, and the servo motor will continue to close the regulator valve on the gas cylinder. The MQ6 sensor can identify gas leaks from the gas cylinder, gas pipes, or kitchen stove burners. One significant advantage of this system is its ability to shut off the gas cylinder supply, indirectly preventing accidents and injuries. The system's design is tailored to accommodate the standard size of gas cylinders used in residential homes, with domestic consumers as the target user group.
