The increasing global energy demand drives the search for efficient and sustainable renewable energy solutions. Solar panels have become one of the most widely used technologies; however, their efficiency remains limited when installed in a static position. This research aims to analyze the performance of a single-axis auto tracking system on a 10WP solar panel integrated with the Internet of Things (IoT) for real-time monitoring, specifically in powering a portable powerbank. The research method employed was a quantitative experimental design with three testing scenarios: powerbank charging using an auto-tracking solar panel, a static solar panel, and conventional household electricity as a comparison. Charging data were collected via an IoT system integrated with the Blynk application in real-time. The results indicate that the auto-tracking system increased charging efficiency by around 10%, compared to only 6% with a static panel in one hour. This performance is nearly equal to household electricity charging, which reached approximately 10–11%. The study concludes that the single-axis IoT-based auto-tracking system significantly enhances the performance of small-scale solar panels and holds strong potential for portable energy solutions in remote areas.

This classroom action research investigates efforts to enhance sixth-grade students’ ability to work together in Natural and Social Sciences (IPAS) learning at UPT SDN Unjuruiya No. 45 Selayar Islands by implementing the Team Pair Solo cooperative learning model. The study was conducted to address students’ low collaboration skills and limited positive learning attitudes, which impeded the achievement of optimal learning outcomes.

Data were collected through observation, field notes, and learning attitude assessments, then analyzed descriptively to determine changes in performance. The findings indicated a significant improvement in students’ cooperative skills, as reflected in the increase in the average percentage of collaboration indicators from 69% in Cycle I to 92% in Cycle II, covering aspects of participation, communication, responsibility, tolerance, and emerging leadership. Furthermore, students’ learning attitudes also improved, with mastery increasing from 45% in the initial condition to 100% in Cycle II, and an average score of 87 surpassing the minimum completeness criterion (KKTP) of 70. These results demonstrate that the Team Pair Solo model effectively fosters collaboration while strengthening students’ discipline, responsibility, and enthusiasm in learning. Thus, the model is proven to be a relevant strategy for enhancing cooperative skills and positive learning attitudes in IPAS instruction at the elementary level.

This study examines how changes in company value are affected by profitability, liquidity, and asset structure using a case study of PT Bank Central Asia Tbk from 2017 to 2024. The Fixed Asset Ratio (FAR), which serves as a proxy for asset structure, the Return on Assets (ROA), which measures profitability, and the Current Ratio (CR), which measures liquidity, are the independent variables in the Price to Book Value (PBV) ratio. The study data came from BCA's public annual financial reports, and SPSS software was used to do multiple linear regression analysis. The findings demonstrate that changes in firm valuation are significantly positively impacted by profitability, suggesting that improved profit performance fosters favorable investor attitudes. On the other hand, throughout the observation period, changes in the company's value are not significantly impacted by liquidity or asset structure. This result is consistent with some earlier research, although it varies in the area of liquidity's impact, indicating a lack of consistency among investigations. Practically speaking, banking management may utilize the study's findings to develop financial plans that emphasize boosting profitability in order to optimize business value. Academically, this study adds to the body of knowledge on the elements that influence corporate value, particularly in the Indonesian banking sector, and addresses the present research gap on the impact of liquidity and asset structure.

This study provides an in-depth examination of the relationship between the implementation of administrative ethics and the quality of civil service performance within the framework of good governance principles in Kota Palangka Raya. Employing a qualitative–descriptive approach grounded in literature-based analysis, this research explores various empirical findings related to public service practices, bureaucratic transparency, regional asset management, and the integrity of civil servants. The analysis reveals that administrative ethics have not been fully internalized, as evidenced by persistent delays in service delivery, employee absenteeism, convoluted procedures, low responsiveness, and weak accountability and regulatory compliance. These conditions indicate a substantial gap between ideal ethical standards and actual administrative practices. The findings further confirm that core values of administrative ethics—such as integrity, discipline, responsibility, transparency, and professionalism—play a determinant role in realizing good governance principles, including transparency, effectiveness, efficiency, accountability, and the rule of law. This study asserts that strengthening administrative ethics is a strategic prerequisite for improving civil service quality and restoring public trust. The implications highlight the need for continuous capacity-building, enhanced integrity among civil servants, and strengthened oversight mechanisms to establish an equitable, accountable, and citizen-oriented system of governance.

This study aims to answer two questions. First, why were there only single candidates in 37 regions in the 2024 simultaneous regional elections? Second, what are the risks of single candidates to democracy and the performance of political parties? The methods used are normative juridical methods with a legislative and conceptual approach. The research focuses on the phenomenon of single candidates in regional elections and its impact on democracy and the performance of political parties in Indonesia. The results of this study show that the phenomenon of single candidates in regional elections indicates weak local democracy and poor performance of political parties in carrying out their functions of regeneration and leadership recruitment. Elite domination, high political costs, and the strong influence of oligarchs make the nomination process non-competitive and reduce the space for alternative candidates. As a result, regional elections are only procedural without substance, widening the democratic deficit and opening space for local bossism and unhealthy power consolidation. If this condition continues, local democracy will move further away from the principles of openness, accountability, and fair competition.

This study aims to provide a comprehensive understanding of how psychological well-being (PWB) influences employee performance through a Systematic Literature Review approach. By analyzing a range of relevant and open-access studies, this review synthesizes key findings to identify patterns that explain the relationship between psychological well-being and work outcomes. The analysis reveals that PWB is a crucial internal factor shaping productive, stable, and consistent employee behavior. Individuals with higher levels of psychological well-being tend to demonstrate stronger motivation, higher discipline, and better adaptability when facing pressure or organizational changes. Beyond its direct influence, PWB also acts as a connecting variable between other determinants such as job satisfaction, work-life balance, and organizational support and improved performance. Overall, the review highlights that psychological well-being is not merely a personal condition but a strategic resource that significantly contributes to long term organizational productivity. Therefore, enhancing employee well-being should be integrated into human resource management practices as both a preventive measure and a long term capacity building strategy.  

This qualitative literature review examines the dysfunctional costs that emerge within Management Control Systems (MCS), a critical organizational mechanism designed to align employee behavior with strategic objectives. Although prior studies have extensively explored the benefits of control systems, discussions on the unintended and often hidden costs remain fragmented. This article aims to synthesize theoretical insights and conceptual debates surrounding four major categories of dysfunctional costs: behavioral displacement, game-playing, operating delays, and negative attitudes. Using a traditional literature review approach, the study integrates foundational theories including agency theory, behavioral control theory, and goal-setting theory with contemporary conceptual findings to identify key behavioral mechanisms that trigger dysfunctional outcomes. The review reveals that overly rigid controls, inappropriate performance targets, and misaligned incentives frequently prompt short-termism, budget slack, manipulation, bureaucratic delays, and psychological strain among employees. These dysfunctional costs can surpass direct control costs and reduce organizational adaptability and long-term performance. The study highlights the need for context-sensitive control design, balanced use of results and action controls, and enhanced attention to behavioral responses when implementing MCS. The implications underscore that effective control is achieved not through tighter rules alone but through thoughtful alignment between control mechanisms, human behavior, and organizational context.

This study aims to examine the effects of workload, job stress, and work spirit on employee performance at PT Victory International Futures Surabaya, a financial services company operating in the highly demanding futures trading industry. Employing a quantitative descriptive–correlational approach, data were collected using a Likert-scale questionnaire and analyzed through multiple linear regression using JASP and Partial Least Squares–Structural Equation Modeling (PLS-SEM) using WarpPLS, which is suitable for addressing multicollinearity issues and relatively small sample sizes (n = 37). The findings reveal that workload and job stress have significant negative effects on employee performance, whereas work spirit has a significant positive effect and emerges as the most dominant predictor. These results reinforce the Job Demands–Resources (JD–R) theory, which posits that job demands such as workload and stress can reduce performance when not balanced with adequate psychological resources like work spirit. Practically, the study recommends that management optimize workload distribution, implement stress management strategies, and strengthen employee motivation to improve performance sustainably. The study is limited by its small sample size and single-company focus, suggesting that future research should expand the organizational context and incorporate additional variables such as job satisfaction or organizational commitment.  

This study aims to analyze the relationship between leadership style and effective communication in the decision-making process within an organizational environment. The leadership style applied by a leader is highly instrumental in determining the quality of communication established between the leader and employees. Effective communication characterized by the clear transmission of information, openness to input, and the ability to listen actively can enhance the accuracy of information, speed, and quality of decisions made. Using a qualitative descriptive approach, this research illustrates how leaders employ specific communication styles to foster employee engagement, strengthen coordination, and minimize misunderstandings during the decision-making process. The findings indicate that the more effective the leader's communication style, the better the quality of the resulting decisions, as the process involves a transparent, participatory, and responsive exchange of information. Thus, effective communication is a key element connecting leadership style with successful decision-making within an organization.

This study examines the influence of transparency and accountability on the performance of public service delivery in Pakpak Bharat Regency.

The findings reveal that both transparency and accountability have a significant positive effect on public service performance, with transparency demonstrating a stronger influence compared to accountability. These results indicate that improving openness in governmental decision‑making processes and strengthening accountability mechanisms in the execution of public duties are essential strategies for enhancing service quality. The study provides practical implications for local governments, emphasizing the need to formulate policies that promote transparent governance and reinforce accountability structures to increase the effectiveness and efficiency of public service delivery. Overall, this research contributes to the growing body of literature on public sector governance by highlighting the critical role of transparency and accountability in improving public service outcomes at the regional level.

This study discusses the design and development of an automatic safety system for a wood cutting machine using Arduino Uno, a PIR (Passive Infrared) sensor, and a servo motor as the main components. The system is designed to automatically stop the movement of the wood cutting machine when human motion is detected around the cutting area, thereby minimizing the risk of work-related accidents. The research method includes hardware design, microcontroller programming, and system response testing using two types of test objects: the human body and a wooden block. The results show that the system operates according to the programmed logic. When the PIR sensor detects human motion, the servo motor stops and the red LED lights up as a danger indicator. In contrast, when no human motion is detected, the servo motor continues to move normally and the green LED remains on as a safe indicator. The system’s average response time is 0.6 seconds, indicating a fast and accurate performance. Therefore, the designed system is considered effective and can serve as a prototype of a simple safety tool to enhance operator safety in wood cutting machines.

Sugar consumption in Indonesia remains high, with diabetes affecting 20.4 million people. This condition has prompted the government to introduce an excise policy on Minuman Berpemanis Dalam Kemasan (MBDK) to reduce sugar intake. Social media, particularly the X platform, serves as a medium for the public to express their opinions regarding this policy. This study aims to analyze public sentiment toward the MBDK excise policy using a lexicon-based approach for data labeling and the Multinomial Naive Bayes algorithm with unigram and bigram feature extraction. The initial results show that the highest performance was achieved using 5-Fold Cross Validation, with an average accuracy of 83%, precision of 84%, recall of 75%, and an F1-Score of 77%. After applying data balancing using Stratified Cross Validation combined with Borderline-SMOTE and limiting the features to the 700 most frequent terms, the model’s performance improved. The best results were obtained with 10-Fold Cross Validation, achieving 86% accuracy, 84% precision, 83% recall, and an F1-Score of 83%. These findings indicate that the Multinomial Naive Bayes model can effectively classify public sentiment regarding the MBDK excise policy after the data balancing process.

This study investigates the impact of intrinsic motivation, workload, and competence on job satisfaction, exploring its implications for employee performance, with job satisfaction serving as a mediating variable. A quantitative approach was employed, utilizing Partial Least Squares Structural Equation Modeling (PLS-SEM) for data analysis collected via questionnaires. The results reveal that intrinsic motivation has a positive but insignificant impact on job satisfaction and performance. Workload significantly improves job satisfaction but does not affect performance, while competence significantly enhances both job satisfaction and performance. Additionally, job satisfaction positively affects employee performance. The mediation analysis reveals that job satisfaction mediates the relationship between competence and workload on performance, but does not mediate the relationship between intrinsic motivation and performance. These findings highlight the critical roles of competence and job satisfaction in improving employee performance, suggesting that intrinsic motivation and workload may require additional factors, such as compensation and work environment, to be more effective.

This study aims to examine the implementation of audit procedures on accounts payable at PT XYZ by KAP Ramli & Rekan, with a focus on compliance with Auditing Standards and effectiveness in detecting material misstatements. Accounts payable are a key component of financial statements representing the company’s obligations to suppliers, requiring accurate presentation for assessing liquidity and capital structure. The study applies a descriptive qualitative method, collecting primary data through interviews with audit staff at KAP Ramli & Rekan and secondary data from relevant literature. The findings show that the audit procedures comply with professional standards, covering comprehensive stages including engagement acceptance, audit planning, risk and materiality assessment, and substantive testing. The planning process incorporates the COSO framework for evaluating internal control, establishes audit objectives based on the five management assertions, and utilizes ATLAS software and Microsoft Excel. KAP Ramli & Rekan apply control testing and substantive procedures, including external confirmations, inspection of supporting documents, review of aging payables, and subsequent payment testing. Risk assessment indicates low inherent and control risks, while detection risk is mitigated through substantive procedures. Overall Materiality is set at 60% of revenue and profit before tax, Performance Materiality at 3% of Overall Materiality, and Threshold Materiality at 3% of Performance Materiality. The study concludes that the audit procedures implemented by KAP Ramli & Rekan align with applicable Auditing Standards and are effective in addressing audit risks related to accounts payable.

This study examines the interrelationship between the implementation of administrative ethics in civil service, the professionalism of State Civil Apparatus (ASN), and the quality of public service delivery at the Provincial Department of Energy and Mineral Resources of Central Kalimantan, employing a qualitative case study approach. Through in-depth interviews, structured observations, and document analysis, the research finds that integrity, transparency, and ethical accountability function not merely as moral norms but as structural foundations that reinforce ASN professionalism in performing service functions, particularly within licensing processes that demand administrative certainty and responsiveness. Empirical findings indicate that professionalism—reflected in technical competence, procedural discipline, and ethical commitment—acts as a catalyst linking ethical values to effective and adaptive public service performance. Nevertheless, the study also identifies structural and cultural impediments, including regulatory inconsistencies, fragmented coordination, and limited training opportunities, all of which hinder the internalization of ethical principles and professional practice within the bureaucracy. Theoretically, the study posits that harmonizing administrative ethics and professionalism is a prerequisite for achieving key indicators of good governance, such as responsiveness, service effectiveness, and institutional accountability. Practically, the study recommends strengthening ethics training, enhancing ASN professional capacity, and advancing managerial reforms grounded in modern governance as strategic efforts to sustainably improve public service quality.

This study presents a comprehensive analysis of reconstruction strategies for mental health services in post-conflict regions of the Middle East, based on a meta-synthesis of 87 policies and intervention programs issued between 2010 and 2023. The findings indicate that 73.4 percent of initiatives did not meet their intended targets due to infrastructural limitations, resulting in a service dropout rate of 62.8 percent. The implementation of the Stepped Care Model shows a 47.2 percent improvement in service access (p = 0.001), while the integration of mental health services into primary health care systems increases overall coverage by 56.3 percent (p = 0.001). Task shifting to community health workers enhances efficiency by 38.9 percent (p = 0.01) with a cost-effectiveness ratio of 1 to 2.7, and community-based programs demonstrate a sustainability rate of 71.2 percent compared to 43.5 percent in conventional approaches. These findings build upon the work of Hamamra et al. (2025) and Werner et al. (2023) on post-conflict mental health interventions and show that hybrid models combining formal and informal structures yield better performance, with an effect size (Cohen's d) of 0.82. The main contribution of this study lies in identifying adaptive implementation patterns that align with resource limitations, socio-cultural dynamics, and systemic reconstruction needs in post-conflict settings.
