Respondents had a low intensity of reading the Koran, namely (1.4%), a moderate intensity of reading the Koran was (94.3%), while those in the high category were (4.3%). Conclution: From the results of this research, it can be concluded that students at the Faculty of Islamic Studies at the Sultan Agung Islamic University, Semarang, have proven that there is no strong relationship between the intensity of reading the Al-Quran and the level of self-confidence (p value > 0.05) using the Spearman test.

Port logistics efficiency is determined not only by the adequacy of infrastructure and the advancement of technology but also by the motivation of the workforce and the overall quality of the work environment. This study investigates how these two factors influence employee performance in the Warehouse Division of PT Yusen Logistics Indonesia. The research employed qualitative methods, gathering data through semi-structured interviews, field observations, and document analysis, with participation from warehouse workers, supervisors, and safety officers. Through thematic analysis, the study found that employee recognition and active supervisory engagement were key contributors to workforce motivation. The work environment, characterized by equipment reliability, safety culture, and yard capacity, directly impacted employee productivity. When both motivation and work environment were favorable, employees exhibited greater procedural compliance, increased throughput, and improved safety practices. In contrast, inadequate motivation and unfavorable work conditions resulted in inefficiencies, downtime, and higher risk-taking behaviors. This study’s findings provide insights into three key areas: maritime economics by highlighting labor’s critical role in port operations, social management by establishing the link between environmental quality and workforce productivity, and vocational education by shaping the training of cadets and practitioners. It underscores that sustainable port operations require human-centered strategies, in addition to infrastructure development. For better performance, companies should prioritize motivating their workforce and improving the work environment to foster a more efficient and safer operational setting.

The implementation of a system commonly known as Good Governance refers to the extent to which the government is able to meet the needs and expectations of society through its policies, programs, and actions. The application of Good Governance is not only related to the effectiveness of bureaucracy but also emphasizes principles of transparency, accountability, participation, and fairness in governance. This is crucial because it has a direct impact on improving the quality of public services, which is one of the key indicators of government success. However, achieving the goals of Good Governance is not an easy task, as in practice, there are various challenges and obstacles that must be addressed. One of the most common barriers is the weakness of internal control systems, which should serve as oversight of employee performance. In addition, there remains a shortage of employees with adequate competencies, as well as work environments that do not fully support the implementation of accountable behavior. These conditions can hinder the achievement of the expected standards of Good Governance. Therefore, deepening and internalizing accountable behavior among government employees is highly important. Accountable behavior is not only related to an individual’s responsibility for their tasks but also to the outcomes of their work, which directly affect the wider community. The findings of this study indicate that accountable behavior has been practiced by employees, yet its implementation must be carried out consistently and continuously. Strengthening accountable behavior is thus expected to enhance the assessment of Good Governance implementation, particularly in the Greater Jakarta (Jabodetabek) region, which is characterized by high levels of governmental complexity and public service demands.

Dengue Hemorrhagic Fever (DHF) is an infectious disease caused by the dengue virus and transmitted through the bite of the Aedes aegypti mosquito. The high risk of dengue transmission is greatly influenced by the density of mosquito larvae which correlates with environmental conditions and community behavior. This study aims to describe the density level of Aedes aegypti mosquito larvae in the working area of the Gandus Health Center in Palembang City in 2025 through the measurement of House Index (HI), Container Index (CI), Breteau Index (BI), Larvae-Free Numbers (ABJ), and Density Figure (DF). The method used was descriptive observational with a purposive proportional random sampling technique on 100 households in three RTs. Data was collected through direct observation using checklist sheets. The results showed that the HI was 66%, CI was 44%, BI was 107%, and ABJ was only 34%, which indicates that the larval density is very high and far below the WHO standard (≥ 95%). The DF value is in the range of 7–9, reinforcing the finding of high vector density. This condition shows that the area is at high risk of dengue transmission. Interventions are needed in the form of regular mosquito nest eradication (PSN), increasing public education, and strengthening the role of jumantic cadres in sustainable vector control.

In many developing regions, the level of savings among employees remains relatively low, making it crucial to understand the factors that encourage or hinder saving behavior. This study aims to examine the influence of financial inclusion, lifestyle, and financial planning on the saving behavior of private sector employees in Jombang Regency, Indonesia. The research employed a quantitative approach by distributing structured questionnaires to 100 respondents who met the eligibility criteria. The participants were selected using a purposive sampling technique to ensure that only employees with sufficient financial exposure and employment stability were included. The instrument used a Likert-scale to measure perceptions and behaviors, and the data collected were analyzed using the Partial Least Squares (PLS) method with the assistance of SmartPLS version 3 software. The findings reveal that financial inclusion, lifestyle, and financial planning each exert a significant and positive effect on saving behavior. Employees who have greater access to financial services and products are more likely to engage in consistent saving practices. Likewise, individuals who adopt a prudent lifestyle and maintain effective financial planning demonstrate stronger saving discipline. These results underscore the importance of integrating financial literacy and planning strategies with broader financial inclusion programs. In conclusion, promoting financial inclusion, encouraging simple and sustainable lifestyle choices, and strengthening financial planning skills can collectively enhance saving behavior among employees. This study provides valuable insights for policymakers, financial institutions, and employers seeking to foster long-term financial resilience and economic security for the workforce.

This study aims to analyze the role of digital communication between parents and schools in improving the effectiveness of student attendance administration and scholarship management at SMA XYZ, and to identify factors influencing its implementation within a sustainable educational ecosystem. The research employed a narrative literature review approach with a comprehensive literature analysis from major academic databases, including Google Scholar and ProQuest Education Database, covering publications from 2010 to 2024. Data were collected through systematic searches using keyword combinations of digital communication, parent-school communication, educational technology, student attendance, scholarship administration, and family engagement, followed by thematic analysis to identify patterns and research gaps. Digital communication demonstrated high intensity (4.2/5 score) with WhatsApp as the dominant platform (65%). While 70% of parents increased their academic involvement, only 45% provided appropriate emotional support. Significant barriers included digital divide (30% infrastructure constraints), digital literacy gaps (25%), and boundary management issues (40% of teachers contacted outside working hours). Digital communication improved administrative transparency and real-time monitoring, though communication patterns remained predominantly unidirectional, with only 35% of parents providing active feedback. The study contributes to Digital Education Communication Theory by identifying paradoxes in digital parental engagement and confirming Digital Divide Theory in educational contexts. Findings expand Family Engagement Theory by revealing how real-time information access can create surveillance parenting behaviors that may be counterproductive to student well-being. Results indicate an urgent need for comprehensive digital communication policies, parent digital literacy programs, and infrastructure support to create an equitable and sustainable digital educational ecosystem that balances accessibility with professional boundaries.

Tuberculosis (TB) is an infectious disease that remains a public health problem in Indonesia, including in Banjarmasin City. Low public knowledge and awareness of clean and healthy living behaviors (PHBS) are also factors in the high rate of TB transmission. Health education is a strategic step in addressing this problem. This study aims to determine the effect of health education using lecture methods and audio-visual media on increasing knowledge in TB prevention efforts in the Alalak Tengah Community Health Center working area. The research design used was a pre-experimental study with a one-group pre-test post-test design approach. The study sample consisted of 51 respondents selected by purposive sampling. The research instrument was a questionnaire administered before and after the education, then analyzed using the Wilcoxon test. The results showed a significant increase in knowledge after the education intervention (p value <0.05). Before the education, most respondents were in the sufficient and poor knowledge categories, while after the education, most respondents moved to the good knowledge category. This indicates that the combination of lecture methods and audio-visual media can effectively increase public understanding. Delivering information through visualization has proven to be more engaging and easier to understand for a wide range of audiences. The conclusion of this study is that this outreach method is effective as a medium for educating the public about TB prevention. A similar approach can be implemented more widely in other regions to support the national TB control program. Consistent and sustainable education programs are essential to maintain high levels of public knowledge. The involvement of health workers, cadres, and community leaders is also a crucial factor in the success of outreach. This strategy is expected to be replicated in other regions with a high TB ​​burden.

This study aims to analyze the influence of training and work discipline on employee performance in CV. Nina Etik Garment Indonesia. The approach used is a quantitative method by distributing questionnaires to 40 respondents who are permanent employees of the company. The independent variables in this study are training and work discipline, while the dependent variables are employee performance. The results of the study show that training has a positive effect on performance, but this influence is not optimal because there are still obstacles in the form of lack of understanding of the material by some employees. This shows that the effectiveness of training needs to be improved, both in terms of delivery methods, the quality of instructors, and the suitability of materials with work needs. Meanwhile, work discipline has been proven to have a significant influence on improving employee performance. Discipline factors, such as punctuality, compliance with rules, and responsibility for completing tasks, are important aspects that drive productivity. This research also found that undisciplined behavior still often occurs, such as being late or not complying with work procedures, which ultimately has an impact on decreasing the effectiveness of the company's operations. Simultaneously, training and work discipline have a significant effect on employee performance, so these two factors need to receive serious attention from management. The practical implication of this research is the need for companies to improve the quality of training programs, both technical and non-technical, so that employees are able to master skills relevant to their work. In addition, the implementation of a more firm, consistent, and measurable work discipline supervision system is also an important strategy to form a professional work culture.

In an organization, human resources are the main asset that plays an important role in achieving organizational goals. One of the factors that affect the effectiveness of employees' work is organizational culture. Organizational culture reflects the values, norms, and habits that are embraced by the same and serves as a code of behavior for all members of the organization. A strong and positive culture can create a conducive work environment, improve work morale, as well as encouraging employee loyalty and productivity. Conversely, a culture that is not aligned with organizational goals can lower motivation and negatively impact performance. Therefore, it is important to understand the extent to which organizational culture affects employee performance.

This study explores the impact of emotional intelligence and work–life balance on organizational commitment, with job satisfaction serving as a mediating variable, in the context of couriers at JNE Denpasar. Utilizing a quantitative research design, the study applies Partial Least Square (PLS) Structural Equation Modeling (SEM) to analyze data collected from 56 participants through a census sampling method. The findings reveal that emotional intelligence has a direct and significant effect on organizational commitment, indicating that employees with higher emotional intelligence tend to demonstrate stronger loyalty and dedication to their organization. However, emotional intelligence does not show a significant influence on job satisfaction, suggesting that other factors may contribute to employees' overall contentment at work. Conversely, work–life balance significantly affects job satisfaction, highlighting the importance of maintaining a healthy equilibrium between professional and personal responsibilities. Despite this, work–life balance does not directly influence organizational commitment. Further analysis indicates that job satisfaction fully mediates the relationship between work–life balance and organizational commitment, demonstrating that employees who achieve a better work–life balance are more likely to be satisfied with their jobs, which in turn enhances their commitment to the organization. However, job satisfaction does not serve as a mediator between emotional intelligence and organizational commitment, implying a more direct pathway between these two variables. These results align with the Theory of Planned Behavior, emphasizing that positive attitudes, reflected through job satisfaction, play a critical role in fostering behaviors associated with organizational commitment. From a practical perspective, the study highlights the importance for companies, particularly in the logistics industry, to invest in initiatives that enhance emotional intelligence and promote effective work–life balance strategies. By doing so, organizations can cultivate stronger employee loyalty, improve engagement, and foster a more committed workforce, ultimately contributing to better organizational performance and stability.

This study aims to analyze the influence of the Problem Based Learning (PBL) model in science education on students’ environmental literacy and science communication skills at SMK Negeri 3 Pekanbaru, focusing on the topic of disaster mitigation. The research employed a causal comparative approach with a post-test only design, comparing two student groups: an experimental class using the PBL model and a control class using conventional teaching. The results revealed a significant difference in environmental literacy, with the experimental class achieving a higher average score (81.86) compared to the control class (62.05). This indicates that the PBL model is effective in enhancing students' understanding, awareness, and environmentally responsible behavior. The PBL approach encourages active student engagement and the application of knowledge to real-world scenarios, which is particularly beneficial in the context of environmental issues and disaster mitigation. By working through problems related to environmental challenges, students are likely to gain a deeper understanding of the topic, which fosters a sense of responsibility towards environmental sustainability. In terms of science communication, although the experimental class showed a higher average score (75.78) than the control class (72.92), the difference was not statistically significant. This may be due to a lack of intensive training in scientific discussions and presentations. While PBL encourages collaborative problem-solving and idea-sharing, students may still require more structured practice in presenting and communicating their findings clearly and persuasively. The integration of more structured activities focusing on science communication skills could further enhance the effectiveness of the PBL model. Overall, the PBL model demonstrates positive potential in improving both environmental literacy and science communication. However, to achieve its full impact, its implementation must be consistent, with a focus on providing students with additional opportunities to develop their communication skills.
