Factors Influencing The Modification Of The Single Storey Terraced House Design In Melaka Tengah

Modifikasi rumah teres telah menjadi ‘trend’ sejak kebelakangan ini. Ia telah dibuat secara berleluasa samada dengan memperolehi kebenaran bertulis dari Pihak Berkuasa Tempatan atau sebaliknya. Bagaimanapun, langkah yang betul tidak diambil untuk mengatasi masalah ini kerana modifikasi rumah teres telah menjadi satu keperluan kepada penghuni untuk menampung pertambahan bilangan isi rumah. Oleh itu, satu kajian telah dibuat dalam mengkaji tahap mengubahsuai dan persepsi isi rumah dari segi personaliti penghuni, citarasa, minat, cara hidup, nilai serta status sosial. Tapak kajian yang dipilih adalah di kawasan Melaka Tengah. Terraced house modification has been a trend in recent years. It has been done excessively either with or without consent from the local authorities. However, there are no proper steps taken to overcome this problem. The reason is that terraced house modification has become a necessity for the resident to cater for the growing number of household. Therefore, a research is done in studying the level of modification and the household’s preference in terms of resident’s personality, tastes, interest, lifestyle, values and social status

PTS and the Built Environment in George Town, Penang

Urban development is complex and contested. This complexity brings forward the realization that urban development’s success is something that depends not only on the way it is designed but also stimulated by people’s acceptance level as well as the government’s commitment. Observation on the study area and its surrounding environment shows a unique landscape where buildings were ranged into several urban development classifications. In this case specifically, this paper adopts the view that ‘...there is no distinct boundary between specific types of development [given that] the decisions on the location of the actual boundaries are frequently made quite arbitrarily’ (Zaremski, 2006 pp 315-316), between the study area and its surrounding environment. This paper investigates the complexities facing a range of key stakeholders groups in managing and developing George Town where the unique landscape suggests the presence of social, cultural and economic inequalities are still being literally instilled into George Town’s development. Keywords: Urban development, buildings and spaces, sense of belonging, self-othering and town management

A Study of Daylight Optimization in Building Design in The Student’s Residential College of UTHM Pagoh

Daylight is often used as a natural light source in order to reduce the consumption of energy in a building and maintain sustainability during the daytime. This study finds that the residential college design is lacking of passive solar control devices to control the daylight penetration into the building which causes discomfort due to direct sunlight problems. This paper identified and analyzed the daylighting performance of the residential college's living area via computer simulations. The daylight performance for the living area of the residential college has been investigated in terms of daylight factor and indoor illuminance. The excessive amount of daylight penetration in the living area can be optimized by upgrading the windows with external shading devices. An external shading device is proposed in this study to avoid the intensity of solar radiation and transfer direct sunlight into the living area. The external shading device design is chosen suitably to the building design. SketchUp software is used to simulate the building design into two 3D models, the first model is a building without shading devices and the second model is a building with shading devices. The 3D models are converted into 2D models using VELUX Daylight Visualizer software. Daylight factor and indoor illuminance are analyzed using VELUX Daylight Visualizer software to calculate the extent of daylight penetrations. Then, the results generated by VELUX Daylight Visualizer software are used to compare the building without shading devices and the building with shading devices. The results showed that the building with shading devices installation are more effective in optimizing the daylight penetration. Therefore, shading devices should be included in the design of the residential colleges to create a comfortable thermal condition for the occupants

Improvised design of grease trap for the usage at the food premises

In Malaysia, there are many pollutions that emitted from the industry. Water pollution can be caused by various sectors, one of it is the industrial sector of the food service. The food service industry in Malaysia is growing up every day and they are the major contributor to pollution that was caused by fats, oils, and grease that are highly discharged from food premises. Grease traps are widely used by most restaurants and food processing industries to reduce oil and grease to an acceptable level before it can be discharged to public sewers [1]. Grease traps are a pipeline that traps the food waste before they enter the sanitary sewer system. The food waste is from the fats, oils, and greases and is usually found in kitchen waste water. Normally, the grease traps are located under the sink because the place is usually contributed to fat, oil and grease. Among the alternatives to reduce the emission levels of fats, oil, and grease, the uses of the grease trap is required to filter the wastewater released from the premises [2]

A compact flat lens antenna with aperture-coupled patch elements

A compact 7 x 7 flat lens antenna design for Xband applications is presented in this paper. A new design with aperture-coupled E-shaped patch elements at 10 GHz is simulated and analyzed. This antenna design is realized by using two back-to-back printed patches with slotted common ground plane and feed horn antenna. The transmission loss obtained of 2.2 dB is sufficiently low. A 320º transmission phase range for the E-shaped patch unit cell is achieved with less than 1.5 dB of deviation in the transmission loss level.The proposed design uses a simple technique and less manufacturing complexity for transmission phase control

An Investigation of Toilet Cleanliness Assessment and People Monitoring at Rest and Service Area (R&R) X and Y

Facility management services are essential for maintaining the effective functioning and safety of buildings. Soft facility management services aim to enhance the work environment by improving efficiency and safety. Poor toilet hygiene due to inadequate care poses a threat to human health and safety. The objectives are to measure the effect of public toilet cleanliness based on the number of people and to analyse the relationship between the level of toilet cleanliness and the number of people. Observation methods were employed to monitor the number of people and evaluate toilet cleanliness from 9:00 a.m. to 17:30 p.m. at R&R X and Y. Linear regression analysis were conducted to determine R2 values for each location and using a one-way ANOVA. The R2 values represent the relationship between the star rating and the number of people. The result shows the R2 valuesfor men’s and women’s toilets at R&R X on weekdays and weekends are R2 = 0.7643, R2 = 0.7784, R2 = 0.2479, and R2 = 0.2245. For men’s and women’s toilets at R&R Y on weekdays and weekends, R2 = 0.1733, R2 = 0.2583, R2 = 0.5591, and R2 = 0.6939. In conclusion, it was found that the R2 values on the men’s toilets at R&R X and the women’s toilets at R&R Y had a strong and moderate relationship to the number of people and star rating. Meanwhile, women’s toilets at R&R X and men’s toilets at R&R Y have a weak relationship between the number of people and the star rating. It important to maintain the cleanliness, user comfort and safety, as well as the overall satisfaction of use, to maintain 5-star rating to ensure thatusers who use public toilets feel comfortable

Study on energy efficiency using building information modelling (BIM) at shared library Pagoh higher education hub

Structures in Malaysia, particularly commercial buildings, have been exceeding the benchmark of building energy usage over the past few years. By maintaining thermal comfort of building under hot climate in Malaysia, air-conditioning system became a basic demand which incessantly operating to fulfil comfort requirement for the occupants in the library.

Experimental study on strength performance of soil reinforced with coconut fibre for PANCHOR–MUAR road

Laterite soil is a typical earthfill material used in road construction base and sub-base layers. Regrettably, such soil becomes soft and saturated under high water content and causes an unsatisfactory performance in withstanding loads from proposed structures. Recently, the use of fibres to improve the soil layer, thereby increasing its geotechnical properties, has been attracting worldwide attention. Therefore, the present study takes a holistic approach to utilise coconut fibre (CF) as sustainable fibre reinforcement to enhance the strength performance of local laterite soil at Panchor - Muar, Johor. It then is used as an earthfill material for construction work. This research focuses mainly on investigating the compaction parameters and bearing capacity of CF–laterite soil. Standard compaction test and California bearing ratio (CBR) test were performed on soil randomly included with three different CF proportions (0%, 0.5%, and 1.0%). Results indicate that the optimum moisture content increased and the maximum dry density decreased as the proportion of CF increased to 1.0%. The CBR value of the reinforced soil recorded a significant increase to 17.42% and 26.14% after being mixed with 0.5% and 1.0% CF proportions, compared with unreinforced soil (7.58%). The coconut fibrereinforcement makes the stabilised soil ideal as a subbase material for road pavement applications. In addition to enhancing soil strength efficiency, CF reuse would also reduce the amount of agricultural waste disposal to landfills and prevent environmental problems
