Material recovery and the effectiveness of 3R’s implementation at Pulau Burung sanitary landfill: a case study / Khairunnisa Afzan Amihamzah

Solid waste is any garbage, sludge, or other discarded material resulting from industrial, commercial and residential activity. The aim of this study is to determine material recovery and effectiveness of 3R’s implementation at Pulau Burung sanitary landfill. To achieve this objective, the composition of solid waste was determined. The domestic waste was quartered until it is reached about 10 kg. Then the process of manual sorting was begun according to its type. The entire sample was taken to laboratory to determine wet mass and dry mass. The result of valuable material can be determined by the sorting process and laboratory study. Interview was done to determine the material recovery in Pulau Burung sanitary landfill. It is divided into 4 categories which are plastic (hard), plastic (soft), paper and aluminum. The observation to see the effectiveness of 3R’s implementation was successfully done within 4 weeks. Results indicated that textile give the highest value on density and moisture content while rubber, leather and glass give the lowest value for this two parameter. In total chemical composition, the food waste has the largest value of the carbon is 7.66 kg. The largest total energy content is plastic which is 29097.04 kJ. The plastic has the highest total weight which is 8.11 kg and by interview the value of plastic (hard) is RM 12.89. There must have parties which can in charge to manage the waste properly to avoid the waste is wasted. It is also will protect the environment from problem associated

Model for implementation of green construction / Afzan Ahmad Zaini

The recent shift from conventional construction to green construction has brought about efficiency and improvement to the construction industry. However, the construction industry is still reluctant to embrace this new development. This circumstance is primarily due to a fundamental problem of the lack of clarity in grasping the concept of green construction. Consequently, it has called for a need to explore the current practice of green construction in the construction industry with which this research has attempted to deal. In this research, a considerable effort was made towards identifying the solution to the problem through the establishment of a green construction model. In the process of establishing the model, four objectives were outlined; (1) To identify the current practice of green construction, (2) To investigate the level of awareness and understanding of the benefits and disadvantages of green construction, (3) To investigate factors of green construction innovation, and (4) To determine the major challenges for the implementation of green construction. The findings used for the establishment of the model were structured and analysed based on the data from 346 usable questionnaires and 25 semi-structured interviews with the aid of SPSS19 and NVivo-9 respectively

Contractors’ Approaches to Risk Management at the Construction Phase in Malaysia

Abstract - Often times, contractors failed to identify, plan, strategize, analyzed, execute, monitor, control and manage the risk involves during construction phase in Malaysia. Consequently, the contractor failed to complete the project on schedule, within client’s budget and quality. The idea of introducing formal risk management among Malaysian contractors during construction phase is seem to be a proactive approach to achieve the project objectives. This paper intends to identify the application of formal risk management among the contractors during the construction phase in Malaysia. Questionnaires and interviews were used. It was found that although the risk management process in Malaysian construction industry has been introduced, most of them are not well structured and not being implemented in a formal manner. Therefore, it is suggested that these contractors should try to implement formal risk management and hope that the construction industry in Malaysia can enjoy the benefits and lead our industry effectively into the next stage of building the nation.Keywords : Risk Management, Contractors, Construction Phase, Malaysia

Contractors’ Strategic Approaches to Risk Assessment Techniques at Project Planning Stage

Abstract — The construction industry is still plagued by poor quality, poor workmanship, poor safety and health environment, and poor practices. The current main problem in the Malaysian Construction Industry is delayed projects under the Ninth Malaysia Plan. The idea of introducing formal risk assessment among Malaysian contractors during the project planning stage is a proactive approach to achieve project objectives. Therefore, this research intends to achieve the following objectives: (1) to investigate the contractors’ approaches of risk assessment techniques at the project planning stage, (2) to investigate the consequences of risk assessment techniques at the project planning stage, and (3) to determine the appropriate risk assessment techniques in dealing with the potential risk factors at the project planning stage. The research methodology applied for this research includes literature reviews and questionnaires. Findings from this research show that the application of risk assessment techniques in the Malaysian Construction Industry is still moderate. Hence, it is suggested that these contractors should try to implement formal risk assessment techniques during the project planning stage in order to achieve the project objectives.Keywords - Risk; Risk Assessment; Contractors; Project Planning Stage; Construction Industry

Cockroaches as potential mechanical vectors for mites infestation the first report in Kuantan

Background: Cockroaches have been long hated by people due to their creepiness and considered as pests. Since mites share the same environment as cockroaches, there are a number of possibilities for mites to be found on the cockroaches. Objectives: Hence, the study aimed to identify the occurrence of mites carried by cockroaches from two food stalls and two restaurants in Indera Mahkota, Kuantan, Pahang, Malaysia. Materials and Methods: A total of 179 cockroaches from the species of Periplaneta americana were caught and processed for identification of mites. The mites were observed under light microscope. Results: Microscopic evidence showed that 102 cockroaches carried mites. The percentage of mites’ occurrence was higher in the food stalls as compared to the restaurants. Conclusions: Overall, the study found that cockroaches potentially serve as mechanical vectors for mites. By reducing the cockroach infestation in food premises, the risk of transmission of dangerous mites via cockroaches also can be reduced

Solidification of Industrial Effluents into Geopolymer Matrix

In this work, geopolymers were produced by reacting metakaolin with industrial effluent from different sources. Instead of directly treating the raw effluent, it would be useful to utilize the effluent and turn it into a value-added substance such as geopolymer, thus will sustain the environment. The right compositions of the materials were determined before mixing to form a cubic shape of geopolymer composite. Each composite will undergo several tests to investigate its properties and characteristics. Such tests include density, Scanning Electron Micrograph (SEM), Thermogravimetric Analysis (TGA), and compressive strength. All samples labeled G1, G2, G3, and G4 which comprises of mixture of metakaolin with KOH solution, OGT effluent, batik effluent, and paper & pulp effluent respectively. They were cured in an oven at temperature of 60oC for 24 hours, and later cooled down for three days at room temperature. Sample G1 showed the best characteristics of density and compressive strength compared to other samples. Similar with TGA, significant weight loss was observed in sample G1, but the other three samples experienced gain in weight after initial exposure to elevated temperature before the weight loss occurred. The reason was due to chemical reactions occurred during the heating process. As for SEM, the microstructural images of all samples were not much different
