Abstract:This study examines the reaction of the Indonesian capital market to the escalation of the Iran conflict in 2026 using an event study approach focusing on energy sector firms listed on the Indonesia Stock Exchange. Market…
t reactions are measured using Average Abnormal Return (AAR) and Trading Volume Activity (TVA). The observation period includes an 11-day event window (t−5 to t+5) and a 100-day estimation period. Statistical tests employed include the Shapiro–Wilk normality test, one-sample t-test, paired sample t-test, and Wilcoxon Signed Rank Test.
The findings indicate that abnormal returns are only significant around the event date but do not differ significantly between pre- and post-event periods. In contrast, trading volume activity shows consistent and significant changes. These results suggest that geopolitical conflict information is more strongly reflected in trading behavior than in price adjustments. This study contributes to the literature by providing sector-specific evidence from an emerging market and highlighting behavioral market responses.
Abstract:This study aims to analyze the effect of Capital Adequacy Ratio (CAR), Non Performing Loan (NPL), and Operating Expenses to Operating Income (BOPO) on Net Interest Margin (NIM) in conventional banks listed on the Indonesia…
ia Stock Exchange during the 2020-2024 period. This study uses a quantitative approach with an associative research design. The sample was selected using purposive sampling and consisted of 11 conventional banks, resulting in 55 firm-year observations. The data were obtained from annual financial reports, official publications, and relevant banking sources. The data were analyzed using multiple linear regression with IBM SPSS Statistics 25, while the Cochrane-Orcutt method was applied to correct positive autocorrelation in the final model. The results show that CAR has a positive and significant effect on NIM, while NPL and BOPO have negative but insignificant effects on NIM. Simultaneously, CAR, NPL, and BOPO have a significant effect on NIM. The adjusted R-square value of 0.099 indicates that the independent variables explain 9.9% of the variation in NIM. These findings imply that capital adequacy remains an important internal factor in maintaining net interest margins, while credit risk control and operational efficiency should continue to be improved.
Abstract:Mental health is a strategic issue in economics because it affects the quality of human resources and regional economic productivity. This study aims to analyze the impact of schizophrenia, depression, and suicidal ideation…
ion on economic losses across provinces in Indonesia and to examine the role of depression treatment as a mediating variable. The study employs a quantitative approach using explanatory research and a cross-sectional design based on secondary data from 2023. Data were obtained from the Indonesian Health Survey (SKI) by the Ministry of Health of the Republic of Indonesia and Regional Gross Domestic Product (PDRB) data from the Central Statistics Agency, with 38 provinces in Indonesia as the units of analysis. Data analysis was conducted using descriptive statistics, multiple linear regression, and causal mediation analysis. The results of the study indicate that schizophrenia, depression, and suicidal ideation have a significant negative effect on economic loss, as proxied by per capita GRDP. Depression is the variable with the greatest negative impact on regional economic productivity. Furthermore, treatment for depression was found to act as a significant mediator capable of mitigating the negative impact of depression on economic loss. These findings indicate that improved access to mental health services contributes to increased community economic productivity and a reduction in regional economic losses. This study makes a theoretical contribution to the development of development economics and health economics research through the integration of mental health variables and regional economic productivity. Practically, the research results underscore the importance of integrating mental health services into regional development policies to improve the quality of human resources and reduce economic loss in Indonesia.
Abstract:Influencer marketing has emerged as a dominant strategy within the digital marketing landscape, particularly in the Indonesian beauty industry. This study investigates how consumers in Makassar City develop and sustain trust…
rust in influencer-based marketing content on social media platforms. Employing a qualitative descriptive approach, in-depth semi-structured interviews were conducted with 20 purposively selected participants who actively consume beauty content on Instagram, TikTok, and YouTube. Data were analyzed using thematic analysis encompassing open coding, axial coding, and selective coding procedures. The findings reveal five core themes: (1) authenticity as the primary driver of trust formation; (2) the negative impact of excessive commercialization on perceived credibility; (3) the role of influencer expertise and product knowledge in legitimizing recommendations; (4) parasocial relationships as amplifiers of emotional attachment and brand loyalty; and (5) consumer skepticism as an emerging critical evaluation strategy. The study demonstrates that trust remains the central mediating variable linking influencer characteristics to purchase intentions. Consumers exhibit nuanced evaluation behaviors, distinguishing between genuine advocacy and sponsored content. The research contributes theoretically by integrating Source Credibility Theory, Parasocial Interaction Theory, and the Trust-Commitment Theory within the influencer marketing context. Managerially, the findings suggest that brands should prioritize authentic, transparent, and expertise-driven influencer collaborations rather than high-volume promotional campaigns.
Abstract:This study examines the implementation of the Quality Control Circle (QCC) system to enhance employee engagement and productivity at Contemporary Amperex Technology Co., Limited (CATL) headquarters and its Indonesian branch.…
nch. As a global leader in lithium-ion battery manufacturing, CATL integrates innovative technology with employee participation to improve work processes and operational performance. QCC is applied as a structured approach that empowers employees to identify workplace problems, develop solutions, and collaborate in continuous improvement activities using quality management tools and the PDCA cycle. The research employs a case study and comparative analysis method to explore differences between the standardized QCC system at CATL headquarters and the more flexible, localized implementation in Indonesia. The study involved permanent employees from both organizations using saturated sampling, with a total of 10 respondents. In addition, a five-day productivity training program was conducted in China and Karawang through lectures, case studies, and project-based learning, evaluated using pre-test and post-test assessments. The findings indicate that QCC significantly improves employee understanding of productivity management, strengthens communication, enhances product quality, reduces quality-related costs, and increases employee engagement, motivation, and organizational commitment in both operational environments
Abstract:The development of financial technology has encouraged the transformation of the digital payment system in Indonesia, one of which is through the implementation of the Quick Response Code Indonesian Standard (QRIS) developed…
oped by Bank Indonesia to integrate various QR code-based payment services. This payment system is expected to be able to improve transaction efficiency, speed up the payment process, and expand financial inclusion for Micro, Small, and Medium Enterprises (MSMEs). However, the adoption rate of digital payment technology in the MSME sector still faces various challenges, both related to technological aspects, user psychological factors, and the influence of the social environment. This study aims to systematically examine the influence of constructs in the Unified Theory of Acceptance and Use of Technology (UTAUT3) on the interest of MSMEs in using the QRIS payment system at Bank Syariah Indonesia with trust and perceived ease of use as mediation variables. The research method used is Systematic Literature Review (SLR) with the PRISMA approach to identify, select, and analyze relevant scientific articles in the 2020–2025 period. The literature search process produced 2,395 articles from a database of reputable scientific journals, then an elimination process was carried out based on inclusion and exclusion criteria so that 71 articles were obtained that were eligible for further analysis. The study stages were carried out systematically through the process of identification, screening, feasibility assessment, and determination of final articles. The results of the study show that the main constructs in the technology acceptance model such as performance expectancy, effort expectancy, social influence, and facilitating conditions have an important influence on interest in using digital payment technology. In addition, additional factors such as trust and perceived ease of use have been proven to act as mediating variables that strengthen the relationship between technology construct and the intention to use QRIS by MSME actors. Trust in system security and ease of use of technology are crucial factors in increasing user confidence in digital payment services, especially in the context of Islamic banking-based financial services. The findings of this study provide a theoretical contribution to the development of a digital payment technology acceptance model based on UTAUT3 and provide practical implications for financial institutions and regulators in increasing the adoption of QRIS among MSME actors. The next research is suggested to develop an empirical model with a quantitative approach to test the relationship between variables more comprehensively in the context of the digital economy in Indonesia.

Abstract:This narrative review explores whether high-potential workers (HiPo) within Indonesian organizations across various sectors consistently exhibit elevated levels of emotional intelligence (EI), and it assesses the relevance…
ce of the Competency Based Model proposed by Boyatzis in the identification and development of HiPos. The review compiles freely accessible scholarly articles from 2024 to 2025, with a focus on research from Indonesia and includes one primary benchmark study on high-potential individuals for comparison, as studies specific to Indonesian HiPo are scarce. Findings reveal that being classified as a HiPo does not necessarily correlate with having high EI. Research directly related to high potential employees indicates that cognitive-intrapersonal skills such as initiative, desire for learning, and the ability to think outside conventional limits are stronger indicators of high potential than emotional-interpersonal skills. Research from various Indonesian sectors, including manufacturing, energy, construction, and public services, suggests that while EI plays a significant role in enhancing employee productivity, work performance, job satisfaction, and effectiveness in management, its influence typically operates through mediating factors instead of serving as a direct predictor. Furthermore, talent management research in Indonesia shows that numerous organizations still depend on performance evaluations and fragmented methods instead of comprehensive competency frameworks. This review concludes that the Competency Based Model is relevant in Indonesian organizations across different sectors; however, it should be viewed as encompassing a range of competencies rather than a single attribute. While EI is valuable, it is not an essential or sufficient criterion for determining high-potential employees.
Abstract:This study conducts a bibliometric analysis of literature (2015-2025) on Indonesian stock market resilience to Federal Reserve monetary policy shocks. Data were collected from Google Scholar using Publish or Perish 8 with…
h relevant keywords. A total of 82 publications with 476 citations (h-index = 9) were identified. VOSviewer was used for bibliometric analysis to map keyword co-occurrence in titles and abstracts. Network visualization revealed three dominant clusters: (1) Federal Reserve monetary policy and capital flow spillovers, (2) market volatility and investor behavior, and (3) financial resilience and domestic policy responses. The overlay timeline indicated a shift from spillover and volatility issues in mid-decade to resilience topics in recent years. The literature suggests that while the Indonesian stock market remains sensitive to Fed rate changes, it has shown growing resilience due to proactive domestic policy interventions
Abstract:This study aims to analyze the influence of international prices, the rupiah–rupee exchange rate, non-tariff measures, and India’s import volume on the export value of Indonesian cloves to India. The research utilizes secondary…
s secondary data for the period 2015–2024. The analytical method employed is the Autoregressive Distributed Lag (ARDL) model to examine both short-run and long-run relationships, complemented by stationarity tests, cointegration tests, ECM estimation, and diagnostic and stability tests. The results show that international prices have a positive and significant effect on Indonesia’s clove export value, consistent with export-supply theory which states that higher global prices increase export incentives. The rupiah–rupee exchange rate displays a positive but insignificant relationship, indicating that exchange rate volatility is not sufficiently strong to influence changes in export value. Non-tariff measures, including SPS and TBT standards, are found to have a significant effect, reflecting the role of regulations in increasing compliance costs while simultaneously enhancing Indian consumer confidence in the quality of Indonesian cloves. India’s import volume also has a significant influence, showing that India’s domestic demand remains a major driver of Indonesia’s export value during the study period. This study is expected to provide insights for policymakers and industry players in strengthening trade strategies, particularly in enhancing the competitiveness of Indonesian clove exports through quality improvements, exchange rate stability, and compliance with non-tariff standards.
