Abstract:Maintaining employee commitment is particularly important in palm oil mill operations, where shift work, physical demands, and limited career development opportunities may affect employees’ attachment to the organization.…
on. This study examines the influence of work-life balance and career development on the organizational commitment of operational employees at the Rimba Belian Palm Oil Mill Unit, Region 5, PT Perkebunan Nusantara IV. A quantitative associative design was employed, involving all 114 operational employees through a census approach. Data were collected using a five-point Likert-scale questionnaire and analyzed through multiple linear regression after completing instrument and classical assumption tests. The findings indicate that work-life balance and career development each have a positive and significant influence on organizational commitment. Both variables also jointly contribute significantly to strengthening employees’ commitment to the organization. Work-life balance showed a relatively stronger contribution, suggesting that employees’ ability to manage work demands and personal responsibilities is particularly important in a shift-based operational environment. This study extends the discussion of organizational commitment to the palm oil agro-industry, which remains less frequently examined than service and public-sector organizations. The findings imply that management should improve shift arrangements, rest periods, access to training, and the transparency of promotion and career development processes to maintain employees’ long-term commitment
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.

d forecasting inflation in Ethiopia and its components using a VAR model. The analysis was based on annual data from 1992 to 2021, encompassing 30 years. The results indicated that all five series were non-stationary at the level but stationary after their first differencing at a 5% level of significance. Johansen's cointegration tests were conducted. The results indicated the presence of at least one co-integration relationship between the variables. The Vector Error Correction Model (VECM) was fitted to model short run and long run relationships among inflation and other macro-econometric series such as GDP growth, government expenditure, money supply, and imports, and the result indicated that the coefficient of error correction term is negative (-0.279), which indicated that the fitted VECM model continues to move toward long run equilibrium and converges. Granger causality tests were employed to explore potential causal relationships. Impulse response analysis and variance decomposition were used to determine the short-run interactions among the variables. Finally, using the fitted model, out-of-sample forecasts were produced, yielding forecasted plots and values for the endogenous variables. According to the forecasted inflation rates for the next five years, prices are projected to decrease by approximately 18.0% in 2022, 6.8% in 2023, and then increase by approximately 8.3% in 2024. Subsequently, prices are expected to decrease by approximately 2% in 2025 and 5% in 2026 over the specified time periods.

Meanwhile, the investment cash flow variable partially has a significant effect on the level of liquidity. And the partial funding cash flow variable has no significant effect on liquidity. Simultaneous research results (F test) state that operating cash flow, investment cash flow and funding cash flow have a value of Fcount > Ftable (3.275 > 2.95) and a significance value of < 0.05 (0.003 < 0.05), So it can be concluded that the operating cash flow, investment cash flow and funding cash flow variables simultaneously have a significant effect on the level of liquidity.
Abstract:This study aims to analyze the determinants of dividend policy and their implications for stock returns among companies listed on the Indonesia Stock Exchange (IDX) during the 2019–2024 period. Specifically, the study examines…
examines the effects of Return on Assets (ROA), Current Ratio (CR), Debt-to-Equity Ratio (DER), Sales Growth (SG), and Firm Size (SIZE) on Dividend Payout Ratio (DPR), as well as the impact of DPR on stock returns. The research employs a quantitative approach using secondary data obtained from the annual financial reports of dividend-paying companies listed on the IDX. The sample consists of 822 firm-year observations selected through purposive sampling. Data analysis was conducted using path analysis with multiple regression models, supported by classical assumption tests including normality, heteroscedasticity, multicollinearity, and autocorrelation tests. The results indicate that during the overall period of 2019–2024, ROA, DER, and SG significantly and negatively affect DPR, while CR and SIZE do not have significant effects. Furthermore, CR negatively affects stock returns, whereas SG and DPR have positive and significant effects on stock returns. The findings also reveal that the relationships among financial performance, dividend policy, and stock returns vary across pre-crisis, crisis, and post-crisis periods. Overall, dividend policy plays an important mediating role in influencing stock returns, particularly during and after periods of financial uncertainty. These findings provide valuable insights for investors, corporate managers, and policymakers in formulating dividend and investment decisions under different economic conditions.
Abstract:Abstract: Roemah Donat Lezat carries out many sales transactions every day because the prices are affordable and the flavors and toppings are increasingly varied, this affects the supply of raw materials at Roemah Donat…
Lezat In managing raw material inventory, you must ensure sufficient inventory for sales, minimizing the time and costs required. So far, the owner of Roemah Donat Lezat does not have a method for anticipating how much supply of basic ingredients there is and only predicts without clear and precise calculations, therefore, sometimes Roemah Donat Lezat takes too little stock even though customer needs at the time the trend is increasing, causing no fulfilling customer requests and sometimes taking too much stock even though customer demand is decreasing resulting in losses, therefore Roemah Donat Lezat always finds it difficult and confused to estimate stock supplies for the following month To overcome the problems above, the author provides a solution using method comparison forecasting calculations, because it can provide a deeper and more detailed understanding of the advantages, weaknesses and relative performance of the two methods used to achieve a goal or solve a problem The method used is Single Exponential Smoothing, which is forecasting used for the short term or usually only for the next month Single Moving Average is a technique for calculating the average of a number from the latest actual values, updated as new values available for use in forecasting in subsequent periods.

s proven to be insufficient to ensure operational continuity. This research aims to design and implement an automated monitoring system to transform this manual approach into a preventive and proactive security framework. The method used is the implementation of an open-source stack consisting of Prometheus to collect metrics from specialized exporters (Blackbox and Domain Exporter), and Grafana for informative centralized dashboard visualization. The system is also integrated with early warning notifications via Telegram for rapid incident response. The result is a functional system with a centralized dashboard that visually displays the remaining validity period of assets using color markers (green for safe status, yellow for early warning, and red for critical status). System testing showed very high accuracy, reaching 100% for domains (MAE 0 days) and 99.45% for SSL certificates (MAE 1.0 days). This system has successfully transformed manual processes into automated and preventive ones, significantly mitigating the risk of human error and ensuring the reliability of digital services.

Abstract:The digital era has significantly transformed lifestyles, particularly in Indonesia, where computer-mediated communication (CMC) now plays a prominent role in human interactions. In public spaces, individuals often prioritize…
itize their digital devices over engaging with those around them. The rise of the internet generation has integrated media and communication into essential elements of daily life. This study focuses on the analysis of hashtag trends related to general elections, such as #capres2024, #cawapres2024, and #pemilu2024, on Instagram, and their influence on user perceptions. It examines the role of hashtags in CMC practices on Instagram during electoral periods. Through the analysis of seven samples, the study reveals that while certain posts align with the electoral purposes of the hashtags, others use these hashtags for visibility without relevance to the elections. The research underscores Instagram’s potential for reshaping political branding and enhancing voter engagement. It demonstrates that the strategic application of hashtags, combined with high-quality visuals and interactive features, can amplify the visibility and impact of political messaging. By integrating CMC and political branding theories, this study presents a framework for understanding how digital tools can foster a more engaged and informed electorate.
