ABSTRACT:

Urban renewal is a vital process in ensuring the sustainability and modernisation of cities, enabling them to remain vibrant, safe, and conducive to contemporary living. In Malaysia, the proposed Urban Renewal Act (URA) signifies a transformative step in this direction. The act addresses challenges specific to Malaysian urban centres while incorporating insights from international models, particularly those of the UK and Japan. We need this act more than ever to better utilise our land, which is a scarce commodity in Malaysia. Urban renewal typically involves redeveloping areas that are underutilised, outdated, or in decline. Countries around the world have adopted urban renewal initiatives to combat urban decay, improve infrastructure, and enhance residents' quality of life. In the UK, the post-World War II era saw large-scale redevelopment efforts, such as the New Towns Act of 1946, which led to the construction of 32 new towns to alleviate housing shortages and decentralise population from congested urban centres. Similarly, Japan enacted its URA following World War II, focusing on the reconstruction of wartorn cities and enhancing disaster resilience through projects like Tokyo’s ARK Hills. In Malaysia, urban renewal has become increasingly essential because of aging infrastructure, congestion, and socio-economic shifts. The URA, scheduled for tabling in Parliament by the first quarter of 2025, aims to rejuvenate dilapidated urban areas while ensuring a balanced approach to development. The Housing and Local Government Ministry (KPKT) has identified 534 potential redevelopment sites in Peninsular Malaysia, with 139 located in Kuala Lumpur alone, representing an estimated gross development value (GDV) of RM355.3 billion. A significant aspect of the URA is its streamlined redevelopment process. Under the current framework, unanimous consent is required under Section 57 of the Strata Titles Act 1985 for terminating strata titles. This has often hindered redevelopment projects. The URA proposes lowering the consent threshold, making it more feasible to redevelop aging properties. Additionally, the act aims to balance development with the rights of property owners. Critics have argued that it may lead to the displacement of low-income residents, particularly among Malays and Indians in urban centres. However, safeguards are in place to ensure equitable compensation for affected property owners, with mechanisms for professional valuation services provided at no initial cost to homeowners.

ABSTRACT:

This paper discussed investigations on the Rapid Chloride Permeability Test (RCPT) and sorptivity test of concretes with replacement of cement by silica fume (SF), Ground Granulated Blast-Furnace Slag (GGBS), and glass powder (GP). The pozzolanic materials content was substituted at levels of 5%, 10%, 15%, and 20% by weight of cement. A series of concrete mixtures with varying proportions of SF, GGBS, and GP were prepared and subjected to both RCPT and water sorptivity test to measure their resistance to chloride ion penetration and rate of water absorption respectively. The specimens were cured under standard conditions and were subsequently tested at different ages. It was observed that all the concrete mixes incorporating different pozzolanic materials exhibited a similar trend in chloride penetrability and sorptivity. This observation can be attributed to the pozzolanic reaction products (CSH) effectively filling the pores between the cement pastes, which creates a denser concrete matrix and enhances durability. Consequently, it is suggested that pozzolanic concrete with up to 15–20% replacement could be suitable for various applications.

ABSTRACT:

Sodium silicate is one of the most common alkali activators for alkali-activated concrete (AAC). The production of sodium silicate leaves a high carbon footprint, which forms the basis for continuing research with a view to alternative synthesis methods using industrial waste materials. In this study, a low-temperature approach to synthesize sodium silicate from industrial by-product silica fume is described, thus eliminating high-temperature processing. Mechanical and microstructural characteristics of AAC activated by different Silica fume-sodium silicate were studied. The Silica fume-sodium silicate were produced under different synthesis regimes, including ultrasonication, heating, and combined methods. The functional groups of resulting Silica fume-sodium silicate were analyzed through FTIR, while UPV, compressive strength, and flexural strength were performed to assess the AAC performance. SEM was done to check the hydration products formed in the AAC. The method of ultrasonication under room temperature (SRT) appeared to provide the best performance compared to other methods with respect to compressive strength, achieving about 34 MPa by day 28.

ABSTRACT:

Concrete production is a significant contributor to global carbon emissions, posing substantial environmental challenges. This study investigates the complete replacement of natural river sand with quarry dust and seashells, alongside the partial substitution of cement with ground granulated blast-furnace slag (GGBS), to produce eco-friendly concrete using industrial waste by-products. Replacement ratios were tested in 10 % increments, evaluating mechanical properties, durability under accelerated acid exposure, porosity, water absorption, carbon footprint, and cost-effectiveness. Results revealed that high seashell replacement levels (80–100 %) reduced compressive strength by up to 21 % compared to the control, while medium replacement levels (30–50 %) improved compressive strength by 5 %, outperforming the control. Accelerated acid tests confirmed that 50 % seashell and 50 % quarry dust replacement offer the best balance of durability and mechanical performance, with minimal porosity and commendable resistance to acid attack. Mid-range replacement levels also reduced carbon emissions by up to 57 %, although transportation emissions increased for seashell-inclusive mixes. Cost analysis highlighted that while material costs remained similar across mixes, transportation expenses significantly influenced overall costs. This study demonstrates the feasibility of using quarry dust and seashells as sustainable fine aggregate replacements, especially at medium replacement levels, where structural integrity, durability, and environmental impact are optimized. These findings highlight the potential of integrating industrial waste materials to reduce the carbon footprint of concrete production while supporting the Sustainable Development Goals (SDGs).

ABSTRACT:

Tons of palm oil fuel ash (POFA) are currently being disposed of at landfills or left untreated in the environment, taking up valuable land space and posing significant hazard to the environment. To address this issue, this study investigates the production of artificial lightweight aggregates (LWAs) using POFA as a raw material through a cold-bonded one-part alkali-activation method. High-volume of weakly pozzolanic POFA and different combinations of GGBS (0%, 10%, 30%) as precursors, and Na2SiO3.5H2O (9% and 12%) as the activator were used to produce the artificial LWAs. The granulation process was systematically investigated, where the influence of granulation parameters (the ratio of POFA and GGBS, activator content, water content, rotation angle, and rotation speed) on granulation efficiency and granulation duration were evaluated. The physical properties including loose bulk density, water absorption, and crushing strength were also investigated. In addition, the phase change after alkali-activation was evaluated. Results showed that the water demand for the aggregates with different combination ranged from 0.3 to 0.46. Increasing the GGBS and Na2SiO3.5H2O content improved the granulation efficiency up to 87.4% and shortened the granulation duration to 7 min. Response surface methodology (RSM) modeling revealed that the optimum rotation angle and rotation speed were 55° and 50 rpm, respectively, resulting in a maximum granulation efficiency of 88.2%. The loose bulk density of POFA-based alkali-activated aggregates (PFAAs) was 595.4–730.3 kg/m3, meeting the requirement of LWAs in EN13055. After 28 days curing, the PFAAs with the GGBS replacement of 30% and 12% Na2SiO3.5H2O exhibited crushing strength and water absorption of 2.4 MPa and 22.4%, respectively. Moreover, a stronger alkali-activation was achieved with 30% GGBS replacement, which improved the performance of PFAAs, as evidenced by the phase analysis.

ABSTRACT:

The utilization of hemihydrate gypsum to produce blocks can be a more sustainable alternative to conventional cement concrete blocks. This study explores the fabrication of semi-dry gypsum-based blocks using the compression forming method to address the drawbacks associated with traditional blocks (clay block and cement concrete block) manufacturing processes, including high energy consumption and lengthy production time. However, the low mechanical strength, low water resistance, and high water absorption of gypsum-based blocks limit their application in construction. Therefore, in this study, semi-dry gypsum-based blocks were prepared using the compression forming method by investigating the interactions between the ground granulated blast-furnace slag (GGBS) content (0%, 20%, 45%), water-to-binder (w/b) ratio (0.20, 0.25, 0.30), and compaction pressure (CP) (10 MPa and 20 MPa). The compressive strength, water resistance, mineralogical composition, and microstructure of the produced gypsum-based blocks were investigated and compared with gypsum-based blocks without GGBS. It was found that adding GGBS can lead to formation of AFt and C-S-H gel when the water content reaches the required level for the reaction. These hydration products are beneficial to improve the compressive strength and water resistance. In addition, the porosity of the specimens was examined using water immersion and the mercury intrusion porosimetry (MIP) method. It was observed that when the w/b ratio is 0.25 or 0.30, a lower CP (10 MPa) should be applied. This is because higher CP (20 MPa) caused paste overflow during the forming process, resulting in undesirable pores having an adverse impact on the compressive strength. The optimal performance was obtained with GGBS content, w/b ratio, and CP at 20%, 0.25, and 10 MPa, respectively. In summary, the compression forming method could produce semi-dry gypsum-based blocks with adequate compressive strength (35.3 MPa) and water resistance (softening coefficient of 0.68).

ABSTRACT:

Scale deposition on pipe walls is prevalent in water distribution systems and is difficult to remove. Commonly, chemical treatment is applied to remove the hard scale. However, it is detrimental to users' health and causes adverse environmental impacts. The need for clean water production for potable and other applications is essential. This study shows the application of magnetic water treatment as a safe and effective method for scale removal in water purification. Permanent magnets were installed in the designed treatment devices that consisted of pipes with scale deposition and the effect of magnetic field on scale reduction was monitored. The scale removal efficiency was evaluated based on calcium concentration in the outlet, after passing through the magnetic field. Magnetic strength was varied between 0.1 T to 0.4 T to investigate its effect on scale reduction. The morphology were analyzed by field emission scanning electron microscope. It was found that magnetic field enhanced scale removal from pipe walls by 46.7%. With respect to the increasing the magnetic field strength to 0.4 T, the efficiency of removal also increased to 30%. Possible mechanisms involved in the magnetic treatment that affects scale reduction such as the effect of magneto-hydrodynamics and magnetically modified hydration are discussed. Magnetic technology is a simple, cost-effective and environmentally friendly treatment approach for clean water production with significant scale removal efficiency. Magnetic treatment can be used either as a stand-alone technology or in water purification systems.

ABSTRACT:

This study uses varying percentages of glass powder (GP) and ground granulated blast furnace slag (GGBS) as partial replacements for Portland cement to investigate their effects on the behavior of the concrete’s mechanical and durability properties. Due to the adverse environmental impacts of cement manufacturing, there have been efforts to replace cement with supplementary cementitious materials (SCMs) to reduce cement consumption while enhancing concrete performance. This study evaluates the effects of adding varying percentages of silica fume (SF) and ground granulated blast furnace slag (GGBFS) on the mechanical and durability properties of the modified concrete. It also evaluates their compressive, tensile, and flexural strength and conducts the Initial Surface Absorption Test (ISAT), carbonation test, and microstructure analysis using scanning electron microscopy (SEM). The research variables are partial cement replacement with varying percentages of 5%, 10%,

ABSTRACT:

Purpose: The primary purpose of this paper is to discuss the impact of urban design on community well-being and the integration of smart cities to emphasise long-term community planning. Design/methodology/approach: A comprehensive literature search was conducted to identify publications addressing smart city integration’s effects on community well-being concerning urban design. SpringerLink, ScienceDirect, Google Scholar, and ScienceDirect were accessed for relevant information, and fifty publications were evaluated in total. The publications contain various kinds of literature on the impacts of urban design on community well-being with smart city integration. The period of the review is from 2019 to 2023. After a thorough review, we will filter out literature with redundancy and deemed unsuitable. Findings: The findings revealed that community well-being focuses on urban people’s overall quality of life. In contrast, urban design emphasises urban areas’ physical layout and organisation to increase livability, and smart cities use technology to improve urban services and sustainability. Research limitations/implications: Through a rigorous, comprehensive review, this study depicts the impact of urban design on community well-being and the integration of smart cities to emphasise long-term community planning. Practical implications: This study offers several components used in community well-being, the impact of urban design and the integration of smart cities in the community. Originality/value: To the best of the author’s knowledge, little effort has been devoted to the impact of urban design on community well-being with the smart city integration. This research helps to close the gap.

ABSTRACT:

There are perennial challenges facing the self-organisation (collective action) of low-cost (social) housing, particularly socioeconomic constraints, complexity in management, and insufficient stakeholder support. Despite numerous housing research focusing on the physical and institutional aspects to address the collective action dilemmas, detailed analyses of the roles of social capital are relatively few. Thus, this review attempts to elucidate and synthesize significant insights utilising Schwitter's social capital framework, focusing on factors conducive to the effective self-organisation of low-cost housing communities. To this end, the review process adhered to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines, where twenty-eight (28) studies were ultimately selected for in-depth analysis. The review suggested that social capital, primarily discussed at two levels (individual and community) encompassing social networks, trustworthiness, and obligations, the collective impact of system control, system trust, and system morality, plays a role in overcoming poverty, overcoming passivity due to individual apathy, assisting local management in rules enforcement, cultivating social relations to transcend market-oriented organisation, and fostering collaboration with external stakeholders in community development. Apart from conceptualising social capital theories in low-cost housing, the findings offer policy insights and practical strategies to policy-makers and local communities.

ABSTRACT:

Rising temperatures due to climate change will impact both the indoor thermal comfort of naturally-ventilated housing and the cooling energy needs of air-conditioned housing in tropical regions. This study aims to evaluate the impact of rising temperatures based on the IPCC A2 scenario on indoor thermal comfort and cooling energy in a typical Malaysian terrace house. It addresses three key questions: 1) Can passive cooling (PC) achieve future thermally acceptable conditions? 2) How will PC impact cooling energy with air conditioning (AC)? 3) What is the effectiveness of various PC methods, individually and combined, in controlling indoor climate and saving energy under present and future conditions? We evaluated the effectiveness of eight PC measures—including shading, insulation, solar reflectivity, and nighttime natural ventilation—using EnergyPlus simulations. Results indicate that without PC and AC, indoor temperatures range from 26 to 31 °C, rising to 29–36 °C by the 2050s, often exceeding ASHRAE 55 standards. Currently, combined PC and nighttime ventilation can improve thermal comfort time fraction by up to 87 %. However, by the 2050s, this drops to 38 %, indicating PC alone will be insufficient, and AC systems will be essential. Additionally, in an AC scenario, PC measures reduce cooling energy by 6 % compared to the baseline under future conditions, yet demand is 67 % higher than current conditions. These findings underscore the need for integrating both PC measures and efficient AC systems to mitigate future greenhouse gas emissions from residential sectors in Malaysia and other developing hot climate regions.

ABSTRACT:

Inefficiencies and ineffectiveness in delivering construction projects had negatively impacted the industry for decades. However, the emergence of building information modeling (BIM) technology had influenced the construction process with its many benefits toward project success. BIM benefits included reduced project time and cost, improved team collaboration and communication, and improved project quality and performance. Consequently, BIM applications were claimed to provide more reliable working practices for quantity surveyors (QS), especially in establishing their cost estimates. Despite the well-known benefits that spurred BIM employment around the world, the usage of BIM software in Malaysia was still in its infancy, requiring greater deployment by the QS. Furthermore, the literature was scarce in comparing the use of BIM software by large organizations and Small-and-Medium Enterprises (SMEs). As a result, the primary goal of this study was to identify the numerous challenges associated with the adoption of BIM software in both large and SME quantity surveying consultancy firms. Apart from that, this paper identified the availability of BIM software in the construction sector as well as the use of BIM software in those consultancy businesses. A quantitative technique was used, with 393 questionnaire survey forms issued to Malaysian QUANTITY SURVEYING consultant businesses. The data was then analyzed using the Statistical Package for the Social Sciences (SPSS) to generate a reliable and valid result. According to the findings, Cubicost software was the most popular software used by QS specialists. Notably, the results revealed that SMEs face greater challenges than large organizations, particularly those connected to professional help, finance, and time, as well as technical issues. Because large corporations and SMEs differed in nature, this study could provide new insights to policymakers in aiding companies of various sizes in their BIM transformation process. The findings called for more policymakers to work together to improve practitioners' understanding of BIM-based technology. The difficulties of SMEs must be recognized, and policymakers must bridge the gap between large and SMEs to bring Malaysia's construction industry one step closer to a new era of digitalization.

ABSTRACT:

Property stigma refers to some characteristics, features, social values, or an event relating to land and buildings that can create a negative perception of a building, land, project, or neighbourhood area. It was identified as a significant factor contributing to the number of overhang residential units in Malaysia. This paper aims to develop a Conceptual Framework of a stigmatized dimension model for residential overhang properties that can assist the decision-making of the property market players (developers, planners, and property consultants). This study utilizes a desktop analysis that reviews previous scholars' conceptual frameworks. The conceptual paper develops four (4) stigma-related variables: Environmental stigma, phenomena stigma, neighbourhood stigma, and structural stigma. However, it is not an empirical investigation of property overhang since this paper needs to review in detail all the factors that influence the property overhang. The proposed conceptual framework will provide valuable insights into the stigmatized dimension of property overhang from the buyer's perspective. This paper provides an essential conceptual framework that will assist the property market players enhance their housing development and sales strategy, thereby increasing the bottom line. Subsequently, this will improve the property market efficiency and meet the demand and supply requirements.

ABSTRACT:

Artificial intelligence (AI) is a key driving force of the fourth technology revolution, and it has become a trend in a variety of professional industries, including the construction sector like BIM. The emergence of ChatGPT has led to numerous research investigating the possibility that using AI chatbots in the workplace will be more productive. Nevertheless, there have been limited studies and no holistic understanding of the feasibility of the new and emerging AI technology in the Quantity surveying (QS) industry. With an assistance of AI chatbot, the role of QS will have significant changes. This research aims to review the existing research on the impacts of AI on QS and if it will eliminate the need for QS. Eighteen (18) relevant journal papers were carefully selected using the PRISMA statement. A thematic analysis was carried out to determine the relevant topic's themes and sub-themes. This study presents three (3) major themes: types, limitations, and impacts, followed by twenty-one (21) sub-themes. The research findings suggest that while AI chatbots have the potential to influence the QS professions, the specific nature and significance of these impacts remain uncertain, warranting further investigation.

Numerous studies have revealed the personality impacts on career development variables, including career choices, vocational interests, career decision-making and work satisfaction. Despite these advancements, a gap remains in understanding how personality differences impact the construction industry. This paper aims to synthesise research on personality typologies in the built environment by utilising Myers-Briggs Type Indicator (MBTI) as a framework. A systematic literature review, guided by the PRISMA 2020 flowchart, analysed 14 scholarly articles. This paper identified a composite profile of effective personality preferences across various built environment roles, including architects, interior designers, project managers, engineers, general construction workers and built environment undergraduates. The findings indicated that individuals in built environment predominantly exhibit Extroversion (E), Thinking (T) and Judging (J) traits. Certain personality types, such as ISTJ and ESTJ were the most frequently observed personality types across the built environment, while ENTP, INFP, ESFJ, ISFJ and ISFP were less common. The greatest difference across construction disciplines were found in their preferences for information-gathering, namely the Sensing/Intuition (S/N) dimension. The implications of these similarities and differences are discussed in both organisational and academic settings. The review also examined how these personality preferences affect teamwork and leadership, project management success, academic performance, work productivity, safety behaviour and risk preferences, creativity and career decision-making. Assuming that certain personality types can be attracted to a certain field or profession, the implications of these findings extend to practical applications for employers in retaining individuals with specific personality types. This paper contributes significantly to the temporal development of personality research by elucidating the personality distribution in the built environment over the past decade (2013-2023). This paper also demonstrates the utility of MBTI as a personality assessment tool in guiding undergraduates seeking alignment with their professional interests.

ABSTRACT:

In what way could a new unproven board offer solutions when Rehda and PPK members are already admitted as registered property managers under BOVAEP and its representatives are board members of BOVAEP?

The current debate on the property management-building management issue can be examined from the public policy perspective. The proposal to establish a rival regulatory Board of Building Managers (BOBM) versus the Board of Valuers, Appraisers, Estate Agents and Property Managers (BOVAEP) by the Ministry of Housing and Local Government (KPKT)  impinges on public policy affecting the property management industry.

Public policy refers to the decisions, actions and programmes implemented by governments to address societal issues or achieve specific goals. The creation of a new regulatory board is a deliberate government action aimed at influencing behaviour, regulating industries or protecting public interests. It falls within the purview of public policy as it involves the formulation and implementation of rules and regulations that have significant implications for society. The affected stakeholders are the graduates of property management, strata property owners, tenants, occupiers, joint management bodies (JMBs), management corporations (MCs), property management professionals, professional bodies, etc.

The establishment of a rival regulatory board, while intended to address certain perceived shortcomings, can also introduce new challenges and weaknesses. Here are some potential drawbacks:

1. Increased costs and inefficiencies

With a significant overlap between the functions and roles of property management and building management, the two bodies may duplicate their regulatory efforts, leading to increased costs for both agencies and the professional practice they regulate.

The two different boards may adopt conflicting or overlapping regulations, creating confusion and uncertainty for the practising professionals, strata management bodies, Commissioner of Building (COB), etc. Why reinvent the wheel when the current regulatory system has already been in place since 1981?

Competition between the two boards can lead to bureaucratic conflicts and a lack of cooperation, hindering effective regulations with dire consequences on the well-being of strata owners, tenants and users.

2. Regulatory capture

The new regulatory board itself could be captured by special interests or specific industry groups, thereby defeating the purpose of its creation. The proposal on BOBM is led by developers with vested interest and the proposed board smacks of conflicts of interest. In contrast, BOVAEP is a semi-statutory body supported by the Federal Department of Valuation and Property Services, the National Institute of Valuation (Inspen) and National Property Information Centre (Napic). As a public body, the impartiality of BOVAEP is clear. Why is there a need to transfer some of the property management functions of a public entity to a new board which is controlled by the private sector, especially developers?

3. Undermining public trust

The existence of two regulatory bodies can create confusion and uncertainty among the public, eroding trust in the regulatory system introduced by the Government. The perception of duplication and inefficiency can lead to a loss of public confidence in the government's ability to regulate effectively.

4. Regulatory overreach

The creation of a new regulatory board could lead to increased regulatory burdens on JMBs and MCs. The professionals and management committees of strata properties will need to report to two boards.

With building management being a subset of property management, the two agencies may have overlapping jurisdictions, leading to conflicting regulations and unnecessary monitoring costs resulting in inefficiencies and waste of public funds.

The unnecessary competition between professionals will stifle growth and innovation in the property management industry hindering the competitiveness of the real estate industry in the Asian region.

5. Political motivations

The establishment of a rival regulatory board could be motivated by political considerations rather than genuine concerns about regulatory effectiveness. Political motivations may lead to short-term policy decisions that do not address the root causes of regulatory problems. It is questionable why the Real Estate and Housing Developers' Association Malaysia (Rehda) and Malaysia Shopping Mall Management Association (PPK), having been board members of BOVAEP since 2018, need to request for the establishment of a separate new board while suggestions and recommendations from them could have been offered for deliberations and implementations by BOVAEP for the well-being of the industry. 

6. Unproven to be effective

The creation of a new regulatory board may simply reinforce existing problems or create new ones, rather than addressing the underlying issues. The new agency may be constrained by the same factors that have limited the effectiveness of the existing regulatory regime. In what way could a new unproven board offer solutions when Rehda and PPK members are already admitted as registered property managers under BOVAEP and its representatives are board members of BOVAEP?

Weigh drawbacks against benefits

In conclusion, while the establishment of a rival regulatory board may be seen as a potential solution to certain regulatory challenges, it is important to carefully consider the potential drawbacks and weigh them against the expected benefits. A more effective approach may be to reform the existing regulatory system or to create a more collaborative and coordinated regulatory framework, which the current BOVAEP is practising with an inclusive approach.

ABSTRACT:

The Malaysian economy has gone from the doldrums to being a juggernaut, which has posed many challenges to the health care industry-especially hospitals. Public hospitals in Malaysia have faced an uphill task in upgrading health care services to levels compatible with international standards. In this book, Hong Poh Fan, a senior adviser on facility management for a hospital developer, explores the transition that public hospitals have undertaken with the support of the private sector. The author zeroes in on critical issues, including: - successes and challenges of privatization implementation; - hospital experiences in a Southeast Asian context and how those experiences can be applied elsewhere; and - ways that private development of hospitals has changed over time as well as the rationale of privatization. When people think of what the hospital industry needs, they often focus on having enough doctors and nurses, but when facilities management is lacking, services can be compromised no matter how employees are working at a facility. Join the author as he shares lessons learned over a fifteen-year period of hospital privatization in this detailed examination of how to improve health care.

ABSTRACT:

As concrete is one of the most commonly used construction materials, there is a massive production of cement, which causes cement manufacturing to be an energy-intensive industry. A significant amount of the cost of cement production, ranging from 20% to 25%, is attributed to thermal energy. In addition, the action of mining and burning fossil fuels results in the unfavorable emission of hazardous compounds into the environment. Therefore, the switch from conventional fossil fuels to alternative fuels (AFs) in the cement manufacturing business has attracted attention due to environmental and financial concerns. In this paper, four commonly used AFs are discussed, which are waste tires, municipal solid waste, meat and bone meal, and sewage sludge. It is found that each AF has a unique calorific value and properties, attributed to its source, treatment, and technology. Furthermore, the availability of AF is important as the amount varies depending on the location. In addition, their effects on gaseous emissions from the cement plant and the quality of clinker are found to be inconsistent. Thus, there will not be a single best type of AF option to be used in the cement industry. A good AF should be able to provide sufficient thermal energy while reducing the environmental impacts and costs. A careful analysis and multicriteria decision-making approach are always vital when employing AFs in order to prevent environmental problems, cost increases, as well as clinker quality degradation.

ABSTRACT:

Street art is promoted in most countries to intensify the cultural elements of the cityscape. Although street art provides cultural and social values, its impact on the prices of prewar historic property is still unknown. Therefore, an empirical study that examines the relationship between prewar shophouse prices and street art is needed to improve real estate professionals’ understanding of the historic preservation market. Using pre- and post-models for the years 2009 to 2019, this study systematically determined the actual location of 119 street art objects (in the form of sculptures and murals) and the 852 prewar shophouses sold in George Town, Penang. The price change of prewar shophouses correlates with the number of street art objects within 100 m, 500 m, and 1000 m of the properties. Due to the heterogeneous characteristics of the properties, six primary hedonic models were developed to extract the price premium of street art. This study has shown the impact of street art on a prewar commercial building, where an additional unit of sculpture could increase its price by 8.32%, 1.62%, and 0.74%, based on radii of 100 m, 500 m, and 1000 m, respectively, in the post-model (after 2012–2019). However, a mural painting has no significant effect on the price change of prewar shophouses. In addition, the position of street art (representing visibility) in the model was tested. The result shows that, unlike sculptures that were located at the back of prewar houses, such street art effects contributed positively to the price premium when they were located at the front of the buildings, with each additional unit of sculpture increasing the price premium of prewar houses by 1.13%. Sculptures as street art thus created a positive externality for the city, particularly with respect to the price premium for prewar shophouses.

ABSTRACT:

Malaysia's Shared Prosperity Vision 2030 Strategic Thrust 1 stated that the business and industry ecosystem to be strengthened and expected to contribute almost 50% of the country's GDP. This agenda is indeed in line with Goal 11 of UN-SDG that aims to develop sustainable and resilient cities and communities by 2030. However, due to the result of the global pandemic in 2020, many micro, small and medium enterprises (MSMEs), particularly tourism-services oriented, were heavily affected and, unfortunately, the last to recover. The industry suffered a significant decline in revenue due to halting of operations, travel bans, and lockdowns resulting in delays to the continuity plan of business operations. As a result, there was a reduction in workforce and some of MSMEs were forced to cease their operations. Based on questionnaire-guided interviews of 53 respondents, this paper firstly will deliberate extensive review of the impacts of COVID-19 pandemic on MSMEs in East Malaysia state of Sabah, particularly in tourism-centric regions of Kundasang and Kota Belud areas. Secondly, the explanation of smart GIS solutions through network analyses, in helping MSMEs rejuvenate their business operations as soon as possible during and after the disaster events. The results from GIS Network Analysis for disaster event simulation and outputs show that each case study region reflected differently according to different disaster types and intensities. From the outputs, the study proposed an integrated framework consisting of MSMEs' capital of economic, social, and environmental problem-solving phase, together with an operational framework of Disaster-Business Continuity Plan (DBCP).
