    Experimental Analysis of Flight Altitude for Enhanced Agricultural Drone Spraying Performance
    Effective rice field management and the proper application of agricultural chemicals are crucial for ensuring agricultural product quality. These chemicals control weeds and protect against insect pests, which can harm crop yields and quality. This research explores the relationship between the altitude at which agricultural drones spray chemicals, spray uniformity, and chemical dispersion. The study assesses drone operations at heights of 1m, 1.5m, and 2m above hollow cone nozzles in 2.8m/s wind conditions. It aims to evaluate droplet uniformity and dispersion on water-sensitive paper placed on paddy plants, analyzed with ImageJ software. Results show that at 1.5m height, there's a significantly higher average droplet density, with 162.7 deposits/cm² in the upper region and 161.8 deposits/cm² in the lower region. Additionally, coverage is notably increased, at 55.21% for the upper region and 51.4% for the lower region. This research highlights the importance of optimal drone altitude for efficient chemical application in rice fields, improving crop protection and yield.

    Nowadays, there are lot of concrete waste were produced from demolition, destruction and others. The usage of concrete is not environmentally friendly due to depletion of reserve natural resources, high energy consumption and disposal issues. Construction debris give a large fraction of solid waste disposal problem, and constitutes the large component. By recycling concrete waste for brick production as replacement the other materials, it can reduce the usage of natural resources and disposal problem that have been occur. The aim of this study to determine the sustainability of the recycled concrete by producing a brick using recycled coarse concrete aggregate at nominal size 10mm. An experiment done by comparing the result of the control specimen using 100% natural sand with specimen that have replaced the sand with recycled concrete aggregate for 0%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100%. The result showed the optimum recycled concrete to produce a brick is at 90% replacement of RCCA where the compressive strength and flexural was achieved 9.7MPA and 3.53MPA respectively with 16133.33 kg/m3 of density. The water absorption of green brick is 9.23% and the cost of brick have been reduced from Rm0.26 to 0.20.

    Towards the implementation of inclusive sustainable cities development as one of the Sustainable Development Goals, the imbalance ratio of existing buildings to new construction became overwhelming challenges. Therefore, refurbishment of existing buildings is considered the possible solution to minimizes the environmental impact and upgrading the performance of an existing building to meet new requirements. However, building refurbishment is well-known as a project that comprehends riskier compared to new building projects which lead to limited applicability in current risk management implementation. Thus, in line with an era of digitization construction of the fourth industrial revolution (IR 4.0), the traditional risk management needs improvement from a manual basis to magnifying efficiency using integration of Building Information Modelling (BIM) application. BIM is defined as an advanced technology that assists construction players to produce, communicate, and analyse building models by providing visual tools and a set of data. Therefore, the objective of this research is to identify the potential building refurbishment risk categories and to determine the most critical project lifecycle phase in implementing the BIM applications in order to mitigate the potential building refurbishment project risk. Also, to discover the relationship strength between these two variables. The quantitative method is applied by using a questionnaire form to the certified BIM experts. This research contributes a solid understanding and useful guideline for future practice reference and improvement within the Building Refurbishment Project.

    Complexity factors in influencing the relationship between critical success factors and performance of building refurbishment projects
    Building is an important sector of today’s human life, where it meets the basic needs of modern humans for shelter and as a place for social activity and also to protect from the environmental threat. The importance of this sector is growing in line with the increasing number of population in need of new building development. Unfortunately, the high demand for new building development has become increasingly difficult due to the limited of vacant land available for development as a building development project. Consequently, refurbishment of existing buildings is one way to overcome this issue. However, recent studies have found that the success of the building refurbishment project is still not satisfactory. Previous studies have been conducted to determine the Critical Success Factors of building refurbishment projects, but they do not take into account important aspects of current development namely sustainability, technology and policy as well as Complexity Factors that are synonymous with building refurbishment projects compared to new building projects. Therefore, this study was conducted with the aim of establishing a multi-dimensional model of a building refurbishment project. To achieve this, Critical Success Factors are identified taking into account the sustainability, technology and policy aspects as well as Complexity Factors in influencing the building refurbishment project performance success. In this regard, the study was conducted through a quantitative method using the questionnaire form as a research medium to obtain feedback from the construction organization on the Critical Success Factors and the successful performance of the building refurbishment project. The questionnaire developed was distributed by employing self-administered method among managers to represent construction organizations operating in Kuala Lumpur and Selangor. As a result, 204 of the 240 questionnaires were fully completed. The analysis showed that all of the Critical Success Factors were categorized as critical to the success of the building refurbishment project and even had a strong relationship with the success of the building refurbishment project. The study also found that Complex Factors not only directly influence the success of the building refurbishment project but also have a significant impact on the relationship between the four Critical Success Factors and the success of the building refurbishment project namely project management, environment, economic and policy. Overall, this study met the goals and objectives of the study. Finally, this study outlines strategies that can be implemented by construction organizations that carry out building refurbishment projects not only to achieve better project success but also to impact the construction industry on leading a competitive industry and creating a better human environment

    The Contractors' Perception on the Development of Green Building Projects in Penang
    A strategy to lessen the substantial effects of the building development on the environment, society, and economy is green construction. However, despite the positive effects of green buildings on society, numerous market hurdles prevent the growth of green buildings, particularly in Malaysia. This happens because of the lack of awareness regarding the development of green buildings. Therefore, this study aims to explore the contractor perception of the development of green building projects in Penang. A set of questionnaire survey was distributed among eighty-three (83) contractors representing construction organizations in Penang. The analysis showed that the contractors mostly agreed with the benefits of green building, indicating that the respondents are aware of green building. The results shows that financial factor with mean value of 4.66 is the main factor hampering the development of green buildings, followed by law and regulation factor (x ., = 4.60) and quality factor (x ., = 4.54). Besides, most of the respondents also agreed that improving the professional knowledge among contractors (x ., = 4.70) will encourage the development of green buildings. Immediate action should be taken on the strategy either from their sides or from other authorities. Overall, this research provides insight into the perception of the development of green building projects among contractors, which can increase awareness on green building and contributing to a better environment.
