Abstract

Asahan Regency is one of the regions in North Sumatra Province that has a relatively high level of disaster vulnerability, particularly hydrometeorological disasters such as floods, tornadoes, and landslides. The complexity of disaster risks requires a disaster management model that does not rely solely on the government but involves various actors in a collaborative manner. In line with the Pentahelix approach developed by Ranga and Etzkowitz (2013) and the concept of collaborative governance by Ansell and Gash (2008), the Government of North Sumatra Province has developed the Pentahelix Synergy Movement Program (SIGAP) as a cross-sectoral collaboration model in disaster management. This study aims to analyze the implementation of the SIGAP Program in Asahan Regency with a focus on collaboration between the local government and the business sector as the main actors in the initial stage of the application of the Pentahelix.This research uses a qualitative method with a descriptive approach through interview, observation, and documentation techniques. The results of the study show that collaboration between the government and the business sector in the SIGAP Program has made a tangible contribution to improving disaster management capacity, particularly in terms of funding, provision of logistics, and the acceleration of emergency response. The local government acts as the coordinator and controller of policy, while the business sector provides support through corporate social responsibility programs and operational partnerships. However, the implementation of SIGAP has not yet been optimal due to weak collaborative institutions, the absence of strong partnership regulations, limitations in the integrated disaster data system, and the low level of structured involvement of academics, communities, and the media.

Abstract

The decline in environmental quality due to increasing greenhouse gas emissions is now a crucial challenge amidst the rapid industrialization of the Southeast Asian region. This study aims to empirically test the validity of the Environmental Kuznets Curve (EKC) hypothesis and analyze the effects of economic growth, energy consumption, population, and urbanization on CO₂ carbon dioxide emissions in the five founding countries of ASEAN (ASEAN-5), namely Indonesia, Malaysia, Thailand, the Philippines, and Singapore. Using secondary time series data from 2009 to 2023, the analysis was conducted using a panel data regression approach through the Fixed Effect Model (FEM) method corrected using White diagonal standard errors & covariance estimates to overcome heteroscedasticity and autocorrelation bias. The estimation results show that the economic growth variable (GDP) has a positive and significant effect, while the quadratic economic growth (GDP2) has a negative and significant effect on CO₂ emissions. This combination confirms the validity of the EKC hypothesis which forms the characteristics of an inverted U-Shape curve in the ASEAN-5 region. Through mathematical calculations, it was found that the turning point for the regional economy was at a nominal GDP per capita of 69,117.65 USD. In the control variable, total population (POP) was shown to have a positive and highly significant influence as the main driver of increasing carbon emissions. In contrast, the variables of energy consumption (energy use) and urbanization rate did not show a significant influence on CO₂ emissions at the regional aggregate level during the observation period. The results of this study indicate that most developing countries in the ASEAN-5 are still on the left side of the ecological curve (below the turning point threshold). Therefore, clean energy transition policy interventions, strict carbon exchange regulations, and eco-city spatial planning are needed to reduce emissions without sacrificing the rate of macroeconomic growth.

Abstract

This study aimed to investigate the impact of digital promotion, online advertising, and customer service quality on changes in consumer purchasing behavior on the Tokopedia platform amid the growing competition within the e-commerce industry in Mataram City. The research employed a quantitative method using a survey design. A total of 100 respondents were selected through purposive sampling based on predetermined criteria, with the study focusing on active Tokopedia users who had experience conducting transactions on the platform. Data obtained from the questionnaires were processed and analyzed using multiple linear regression analysis with the support of SPSS version 27 software. The findings revealed that digital promotion, online advertising, and customer service quality significantly influenced the decrease in purchasing activity on Tokopedia. Both the partial and simultaneous tests confirmed that these variables contributed significantly to explaining variations in consumer purchasing behavior. In addition, digital promotional efforts and online advertising were shown to influence consumers’ purchasing intentions, while customer service quality emerged as an important factor in maintaining customer loyalty and continued platform engagement.

Abstract

This study aims to examine the partial and simultaneous effects of employee well-being and work motivation on Organizational Citizenship Behavior (OCB) among employees of PT Hui Shun Indonesia (HSI). The population of this study consisted of all 150 employees of PT Hui Shun Indonesia. A saturated sampling technique was employed, whereby the entire population was used as the research sample. Data were collected through questionnaires and analyzed using multiple linear regression analysis. The results indicate that employee well-being has a positive and significant effect on Organizational Citizenship Behavior, with a significance value of 0.000 (< 0.05). Meanwhile, work motivation does not have a significant partial effect on Organizational Citizenship Behavior, with a significance value of 0.105 (> 0.05). However, employee well-being and work motivation simultaneously have a significant effect on Organizational Citizenship Behavior, as indicated by a significance value of 0.000 (< 0.05). The coefficient of determination shows that employee well-being and work motivation jointly explain 43.1% of the variance in Organizational Citizenship Behavior, while the remaining 56.9% is influenced by other variables not included in this study. These findings provide practical implications, suggesting that improving employee well-being can encourage extra-role behaviors that contribute to enhanced organizational performance, productivity, and competitiveness, thereby supporting economic growth and development through the strengthening of human resource quality.

Abstract

The trade war between the United States and China, which began in 2018, has triggered shifts in trade flows and the relocation of investments to various Asian countries. These developments have the potential to affect fiscal revenue through changes in international trade tax revenue. This study aims to analyze the effects of imports, Gross Domestic Product (GDP), exchange rates, and the trade war on international trade tax revenue in five Asian countries during the period 2010–2023. This study employs panel data regression using the Fixed Effects Model (FEM). The results indicate that imports and exchange rates have a positive and significant effect on international trade tax revenue. Conversely, GDP has a negative effect, suggesting a shift in the government’s revenue sources from trade taxes toward domestic taxes as the economy grows. The trade war dummy variable also has a positive and significant effect, indicating that the U.S.–China trade war increased international trade tax revenue in several Asian countries through the diversion of trade flows and the relocation of economic activities. These findings suggest that global trade dynamics play an important role in shaping a country’s fiscal revenue.

Abstract

Indonesian female workers still face gender inequality in the labor market, which is reflected in the low wages they receive despite their relatively high levels of productivity. This study aims to estimate the effects of female workers, female labor productivity, females’ years of schooling, and female’s life expectancy on female workers' wages in Indonesia from 2020 to 2024 a panel data regression method with a Fixed Effects Model (FEM) approach. The data was obtained from the Central Statistics Agency (BPS) in 34 provinces in Indonesia from 2020 to 2024. The results show that female workers and females’ life expectancy have a positive effect on female workers’ wages. Meanwhile, female worker productivity and females’ mean years of schooling have no effect on female workers’ wages. These findings indicate the importance of strengthening labor policies that support gender equality through expanding formal employment opportunities for women, improving the quality of women's health and education, strengthening protection for female workers and implementing a fairer wage system without gender discrimination in order to sustainably improve the welfare of female workers in Indonesia.

Abstract

This study aims to analyze the influence of motivation and communication on employee retention in educational institutions, with organizational citizenship behavior (OCB) serving as a mediating variable. Data were collected via questionnaires from employees across various educational institutions and analyzed using Partial Least Squares Structural Equation Modeling (PLS-SEM). The results indicate that motivation has a positive and significant impact on both employee retention and OCB. Communication also plays a crucial role in enhancing employee retention and, notably, has a significant effect on OCB. OCB was found to be a significant mediator in the relationship between motivation and employee retention. However, the moderating effects of communication on the relationships between motivation and OCB, as well as between OCB and employee retention, were not significant. These findings highlight the importance of boosting employee motivation through career development programs and reward systems, alongside open and transparent communication, to foster OCB and improve retention within educational institutions. This study offers both theoretical and practical contributions to understanding the mechanisms underlying employee retention in the education sector.

Abstract

This study examines digital marketing strategies employed by PT Seema Electra Sejahtera to enhance corporate competitiveness in the environmental consulting services industry. A qualitative approach with an intrinsic case study design was adopted to obtain an in-depth understanding of the company's digital marketing practices within its organizational context. Data were collected through semi-structured interviews with the President Director, Marketing Manager, and marketing staff, supported by non-participant observation, documentary analysis, and tertiary sources. Data credibility was ensured through source and methodological triangulation, member checking, and an audit trail, while analysis followed the interactive model of Miles and Huberman, including data reduction, data display, and conclusion drawing. The findings reveal that the company utilizes its corporate website, social media platforms, and search engine optimization (SEO) to improve visibility, disseminate service information, and strengthen its professional image. However, digital marketing has not yet become the company's primary marketing strategy because project acquisition remains largely dependent on LPSE, e-procurement systems, professional networks, corporate reputation, service quality, and repeat clients. Although supported by competent human resources and adequate technological infrastructure, the effectiveness of digital marketing is constrained by limited dedicated personnel, inconsistent digital marketing management, and the absence of systematic performance evaluation. The study recommends strengthening digital marketing integration to improve organizational competitiveness.

Abstract

This study examines the role of financial influencers, financial content exposure, social influence, fear of missing out (FOMO), and self-control in Generation Z's investment decision-making in the digital era. A quantitative associative research design was employed involving Accounting students at Universitas Muhammadiyah Surakarta from the 2022–2024 cohorts. A total of approximately 310 respondents were selected through purposive sampling from a population of 1,386 students (Sugiyono, 2023). Primary data were collected using an online questionnaire with a five-point Likert scale and analyzed using SPSS through descriptive statistics, validity and reliability tests, classical assumption tests, and multiple linear regression, followed by the coefficient of determination (R²), F-test, and t-test at a 5% significance level (Ghozali, 2021). The findings reveal that financial influencers and self-control have positive and significant effects on Generation Z's investment decisions. In contrast, financial content exposure, social influence, and fear of missing out (FOMO) do not significantly influence investment decisions. These results suggest that investment decisions among Generation Z are primarily driven by trusted financial sources and the ability to exercise self-control rather than by social pressure or extensive exposure to financial content.
