The impact of overtime duration variations on labor productivity in apartment construction projects: A study on engineering and disaster management in the construction sector
Get PDFBackground: Construction projects, especially apartment buildings, often face challenges such as resource limitations, unpredictable weather, and schedule delays, which lead to increased costs and reduced productivity. Overtime is a commonly adopted strategy to address these issues; however, its effect on labor productivity is complex. Methods: This study investigates the impact of varying overtime durations (1, 2, and 3 hours) on labor productivity and Labour Utilization Rate (LUR) for three critical tasks: rebar installation, concrete casting, and formwork installation in the Sky House Alam Sutera project. The Productivity Rating method and LUR analysis were used to evaluate normal productivity and productivity during overtime, with data collected through direct observation, interviews, and project documentation analysis. Findings: The results reveal that while overtime increases daily output, it also reduces productivity per hour as work hours extend. Rebar installation exhibited the most significant decline in productivity, from 493.529 kg/hour during regular hours to 345.470 kg/hour with 3 hours of overtime. Correspondingly, the LUR improved with overtime, with rebar installation increasing from 68% under normal conditions to 72% with 3 hours of overtime. Similarly, the cost of labor increased by 9%–23% due to overtime, depending on the task and duration. Conclusion: The findings suggest that the optimal overtime duration is 1 hour, balancing productivity gains, cost efficiency, and LUR improvements, while prolonged overtime may lead to diminishing returns due to worker fatigue. This study provides insights into managing overtime in construction projects, emphasizing the importance of controlling overtime durations to achieve project objectives efficiently. Novelty/Originality of this article: This study offers an original perspective by examining the impact of varying overtime durations on both labor productivity and Labor Utilization Rate (LUR) in the context of construction projects, using a detailed analysis of three critical tasks
Reputation, trust, price consciousness, and perceived value of guest booking intention: A study of co-living users
Get PDFBackground: The growth of the home-sharing accommodation industry in recent years has increased significantly. Co-living, one of the home-sharing industries, has become an attractive trend in urban real estate because it offers flexibility and shared accommodation. The intention to book co-living accommodation is an important factor in the success of the home-sharing business, especially in co-living services. This study aims to analyze the factors that influence guest booking intention using attribution theory, which consists of reputation, trust, price consciousness, and perceived value variables. Method: This research uses an explanatory type of research with a quantitative approach by distributing online questionnaires to 155 people in JABODETABEK area who have used co-living. Research data analysis using simple linear regression and the Sobel test shows a positive and significant influence between reputation, trust, price consciousness, and perceived value variables on guest booking intention. Findings: The study found that reputation, trust, price consciousness, and perceived value all positively influence guest booking intention. Reputation has a positive influence on booking intention, mediated by trust, while price consciousness affects booking intention through perceived value. Conclusion: Reputation, trust, price consciousness, and perceived value are crucial in shaping guest booking intention in the co-living industry. The mediation of trust and perceived value highlights the complex dynamics influencing booking decisions. Novelty/Originality of this article: This study provides a novel analysis of the factors influencing guest booking intention in the co-living industry, highlighting the mediating roles of trust and perceived value, with a focus on reputation and price consciousness
The influence of the international monetary fund (IMF) on economic liberalization development in Egypt: A geopolitical and economic analysis (2011-2018)
Get PDFBackground: International Monetary Fund (IMF) as an international financial institution implements a liberalism policy for countries that need loan funds. In 2016 after lengthy negotiations and numerous rejections from the public, the Egyptian Government finally made an agreement with the IMF. This agreement is the first agreement after the revolution in Egypt in 2011, which was also assessed as a result of implementing IMF policies. Egyptian society feels that the policies set by the IMF did not bring prosperity evenly. The influence of the IMF on the implementation of economic liberalization policies then becomes an interesting thing to study. Methods: This study aims to analyze the background and influence of the IMF on the development of economic liberalization in Egypt and explain how Egypt implements the policies set by the IMF. This research is a qualitative research with a descriptive analytical approach. Findings: The theory that will be used in this research is the institutional neoliberal theory developed by Robert Owen Keohane and elaborated with the concept of interdependence. Conclusion: This research concludes that the negotiation agreement between the IMF and Egypt in 2016 is because the Egyptian economy is in a state of decline. And the program agreement that was agreed with the IMF as an international organization had an influence on Egypt both in monetary, fiscal and structural terms. Novelty/Originality of this article: This study reveals that Egypt's IMF-backed reforms stabilized the economy but primarily benefited the elite, while the poor faced harsher conditions. Despite these negative social impacts, Egypt continued the reforms due to its interdependence with the IMF
Towards a sustainable blue economy: An evaluation of Indonesia's post-production non-tax state revenue policy using Dunn’s criteria
Get PDFBackground: The Government of Indonesia has regulated the Non-Tax State Revenue (PNBP PHP) policy in relation to the vision of developing a blue economy-based capture fisheries sector. The policy aims to make a substantial transformation in the fiscal policy landscape. This study attempts to evaluate the PNBP Post-Production policy using Dunn's three policy evaluation criteria. Methods: In relation to these objectives, the researcher uses a post-positivist approach to obtain research results. Data collection was conducted through qualitative methods with several stages, namely in-depth interviews, field observations, and literature studies. Findings: The results show that the Post-Production PNBP policy can provide benefits for payers and tax authorities because PNBP is levied on the weight of real catches, not on estimates as regulated by Pre-Production PNBP. However, the PNBP policy does not meet Dunn's three criteria related to effectiveness, efficiency, and fairness. Based on the efficiency criterion, the policy is burdensome for payers and tax authorities. PNBP policy when viewed from the criteria of justice has fulfilled the benefit receive principle. However, the tariff index has not fulfilled the principle of nondiscrimination due to the differentiation of tariffs between vessel sizes which is no longer relevant. Conclusion: The government needs to further evaluate the policy of the Non-Tax State Revenue Policy for Collection of Fishery Products (PNBP PHP) in order to support the development of the capture fisheries sector based on the blue economy, at least the Post-Production PNBP policy must fulfill the three Dunn criteria. Novelty/Originality of this article: This research suggests the adoption of technology in each port that can meet the criteria of policy effectiveness and efficiency. In addition, it is necessary to reformulate the tariff index to meet the criteria of fairness
Impact analysis of forest and peatland landscape change: Socio-economic and environmental implications
Get PDFBackground: Peat forest land is highly susceptible to burning and releasing stored carbon and greenhouse gas emissions into the earth's atmosphere when its water content is used for plantations, agriculture and other uses. This study was conducted to analyze the progress of forest and peatland landscape development in Katingan District, Central Kalimantan Province and its potential ecological impacts on the environment. Methods: This research approach uses a quantitative approach to analyze landscape changes that occur within five years, namely in 2015 and 2020. The research was conducted by examining secondary data only. Finding: The results of this study show that the contrast in land increase between forest and peat land and non-forest land is not significant, as shown by the ratio of forest and peat land/non-forest land which increased by only 0.02 or 2% between 2015 and 2020. If the area of non-forest land continues to increase in the future, Katingan Regency is predicted to have a higher vulnerability to natural disasters. Conclusion: The results of land cover/landscape change in Katingan District, both forest and peatland (consisting of primary dry forest, secondary dry forest, secondary mangrove, swamp, swamp scrub, and secondary swamp forest) and non-forest land, both increased in area, respectively by 26,532.61 ha and 4813.64 ha from 2015 to 2020. Novelty of This Study: This study provides a unique perspective on the ecological impact of land cover changes in Katingan District by analyzing a five-year landscape transformation using a quantitative approach
International marriage migration from Thailand to India: The socio-cultural and religious intermediary in the digital era
Get PDFBackground: This qualitative study examines the factors driving the international marriage migration of Thai women to Indian men in the digital age, focusing on how socio-cultural and religious themes are expressed through their YouTube channels and Facebook pages. Methods The research uses a desktop methodology to analyze secondary data, including publicly available videos, posts, comments, and interactions from six selected YouTube channels, each boasting over 100,000 views and active user communities relevant to the topic. Data collection occurred from September to November 2024. The study integrates concepts from globalization, Robert Sternberg’s Triangle Theory of Love, intercultural communication, identity, and diaspora to dissect these dynamics by content analysis. Key findings include the stages of meeting and falling in love, the adaptation process to new family environments, and content produced on social media addressing themes like food culture, religious practices, cultural values, and child-rearing methods. The audience's reflections on these topics were also analyzed. Finding: Although India's population of Thai wives is relatively small, their YouTube and social media platforms have attracted international attention. This visibility can foster greater socio-cultural and religious understanding between India and Thailand, promoting interconnectedness and cooperation in the region. If the Thai embassy and consulates in India were to facilitate a network for these Thai wives, they could effectively champion “Thainess” within the context of “Indianness.” As “civilian ambassadors,” these women could enhance cultural diplomacy between the two nations, contributing to stronger ties and mutual respect. Conclusion: No studies have investigated Thai wives in India functioning as YouTubers. This research underscores the meaningful and authentic socio-cultural and religious perspectives disseminated by these women through digital channels, perspectives largely unacknowledged within the Thai context.
From awareness to action: Understanding urban community participation in tree planting initiatives
Get PDFBackground: Tree planting activities in urban areas are an important strategy to enhance the environmental quality for the communities living in those regions. Tree planting offers numerous benefits that can be experienced in daily life, which is why it is essential to raise awareness, particularly among urban communities, to engage in tree planting around their residential area. In addition to the benefits gained from tree planting, there are also potential drawbacks that can arise from planting trees in urban areas. This article aims to examine the awareness behaviour of tree planting and the barriers faced by urban communities in this regard. Methods: Through a literature review and a study of the perceptions of the community in Tangerang City, this research identifies the factors influencing individual decisions to engage in tree planting and measures the positive impacts generated by such initiatives. Findings: The primary motivations of residents for tree planting are to improve air quality, reduce temperatures, and simultaneously enhance the beauty and aesthetics of the surrounding environment. Additionally, participation in urban tree planting is often influenced by environmental awareness, community support, and government policies. Some of the benefits of tree planting include improved air quality, CO2 emission absorption from human activities, and the enhancement of green spaces that positively impact public health. Conclusions: This study concludes that increasing awareness of the benefits of tree planting, along with support from the government and communities, can encourage broader participation in these activities. Policy recommendations include promoting tree planting programs, providing incentives for participants, and strengthening cooperation among stakeholders, all of which are expected to achieve more optimal outcomes in urban environmental management. Novelty/Originality of this Article: This study offers a novel perspective by exploring the awareness behavior and barriers faced by urban communities in tree planting, particularly in Tangerang City, Indonesia. Unlike previous studies that primarily focus on environmental impacts, this research integrates social perceptions to provide a comprehensive understanding of community motivations and challenges
The impact of sedentary behavior on blood glucose levels in type 2 diabetes mellitus patients: A literature review
Get PDFBackground: Sedentary behavior, characterized by prolonged sitting or lying down, is increasingly recognized as a major health risk, particularly for individuals with type 2 diabetes mellitus (T2DM). Previous studies have shown that sedentary lifestyles can exacerbate glucose control issues, leading to poor glycemic regulation and an increased risk of complications. This study aims to explore the relationship between sedentary behavior and blood glucose levels in T2DM patients, highlighting the potential benefits of interrupting sedentary time with physical activity. Methods: This research utilized a comprehensive literature review methodology, analyzing studies published over the past decade to assess the impact of sedentary behavior on glycemic control in T2DM patients. The review focused on both observational studies and experimental trials, employing data from clinical studies and patient monitoring. Findings: Prolonged sedentary behavior was found to be associated with worsening glucose control, including prolonged hyperglycemia and reduced euglycemia. Interrupting sedentary time with short bouts of physical activity (e.g., walking or light exercise) was shown to significantly improve glucose uptake in skeletal muscles, providing effects similar to anti-diabetic medications. Consistent and frequent interruption of sedentary behavior resulted in improved daily blood glucose control, potentially offering a non-pharmacological intervention for T2DM management. Conclusion: The study underscores the importance of reducing sedentary behavior in T2DM patients as a strategy to enhance blood glucose control and prevent complications. Regular physical activity interruptions can serve as a critical non-pharmacological intervention to manage and control blood glucose levels. Novelty/Originality of this article: This review contributes to the growing body of evidence on the health risks of sedentary behavior in T2DM patients, emphasizing the potential of simple lifestyle interventions to improve glycemic control, which has been insufficiently explored in previous literature.
The effect of audit delay, audit fee and audit opinion on auditor switching: Empirical study of energy sector companies on the Indonesia Stock Exchange in 2020-2023
Get PDFBackground: The energy sector requires large long-term investments for infrastructure and technology development. Therefore, transparency in financial reporting is very important to provide a clear picture of the company's financial performance and prospects for investors.
