This article is a literature review that systematically examines leadership strategies and managerial innovation applied in type C hospitals, with the aim of identifying effective approaches in improving the quality of health services. Type C hospitals as medium-level health facilities have an important role in the referral service system, but often face challenges in the management and provision of quality services. Therefore, strengthening leadership and innovation aspects is crucial to answer the need for sustainable service reform. This study uses a systematic literature review method by analyzing national and international scientific publications published in the 2020–2025 time frame. The focus of the study was directed to the themes of transformational leadership, managerial innovation, and service quality of type C hospitals. The results of the study show that transformational leadership has a strategic role in shaping an innovative and collaborative organizational culture. This leadership style encourages changes in organizational behavior, increased motivation of health workers, and openness to digital transformation. Managerial innovations, especially in the form of digitizing services and strengthening health information systems, have been proven to improve operational efficiency, medical data accuracy, and patient satisfaction. The synergy between visionary leadership and planned managerial innovation creates an adaptive and quality-oriented healthcare ecosystem. However, the implementation of this strategy still faces obstacles in the form of resistance to change, limited resources, and low digital literacy among health workers. Therefore, managerial commitment, human resource capacity development, and consistent policy support are needed to ensure the sustainability of healthcare transformation in type C hospitals.

This study aims to describe the role of school management in developing local culture-based education. Local culture-based education is a learning approach that integrates local cultural values as a contextual, relevant, and meaningful learning resource for students. This study used a qualitative approach with a case study method in an elementary school that has successfully implemented local culture comprehensively in various aspects of learning activities. Data were collected through in-depth interviews, observations, and documentation studies. The results show that school management plays a strategic role in formulating policies, supporting culture-based learning programs, and establishing partnerships with the community for cultural preservation. The principal, teachers, and education staff actively integrate local cultural elements into the curriculum, extracurricular activities, and the learning environment. Despite facing challenges such as limited resources and lack of training for educators, this school is able to demonstrate a strong and consistent commitment to making local culture the foundation for character and identity formation for students. This study confirms that collaboration between stakeholders is key to success in realizing education rooted in local wisdom. By involving parents and the community, schools can create a more inclusive and supportive learning environment. These findings demonstrate that community involvement in the educational process not only enriches students' learning experiences but also strengthens their sense of belonging to local culture. This research significantly contributes to the development of educational models that focus not only on academic aspects but also on the development of student character and identity rooted in local cultural values. Through this approach, it is hoped that students will grow into individuals who are not only academically intelligent but also have an awareness and appreciation for their own culture.

The study of eschatology and logic in Islam represents a significant and intellectually rich area within the broader discourse of ?Aqidah (Islamic creed) and Islamic philosophy. Eschatology, derived from the Greek word eschatos meaning "last," concerns matters of the afterlife, including death, the apocalypse (al-S??ah), resurrection (al-Ba?th), judgment (al-?is?b), heaven (Jannah), and hell (Jahannam). These concepts are elaborated extensively in both the Qur'an and the prophetic traditions (?ad?th). Meanwhile, logic in Islam is not merely a philosophical exercise but serves as an epistemological framework for interpreting divine revelation and deducing legal and theological principles. Islamic logic (al-man?iq) is rooted in both Greek logical tradition—particularly Aristotelian logic—as well as unique Islamic methodologies that integrate rationality with scriptural fidelity. This research aims to analyze selected verses and prophetic traditions related to eschatology and logic, with the objective of understanding not only their linguistic and theological meanings but also their practical implications for human belief systems and ethical behavior. The study employs an interpretive and analytical method (manhaj ta?l?l? wa tafs?r?), focusing on exegesis (tafs?r) of Qur’anic verses QS. Al-A'raf: 187–188 and QS. Al-An'am: 30, as well as relevant ?ad?ths concerning eschatological events and rational thought. These verses were selected due to their direct references to the knowledge of the Hour (?ilm al-s??ah) and the human tendency to demand evidence while rejecting spiritual truth. The findings indicate that Islamic eschatology is framed not around speculative prediction but rather spiritual and moral readiness. The Qur'an clearly asserts that knowledge of the exact time of the Day of Judgment belongs solely to Allah (QS. Al-A’raf: 187), highlighting the limitations of human knowledge and emphasizing submission to divine wisdom.

This study aims to analyze the implementation of the Think Pair Share (TPS) learning model in improving problem solving skills in fractional materials for grade V students at SD Negeri 3 Mantingan. The background of this research is the low ability of students to solve fractional problems, mainly due to procedural misconceptions and lack of opportunities to discuss and construct understanding collaboratively. The method used is the Kemmis and McTaggart model Class Action Research (PTK), which consists of four stages: planning, action, observation, and reflection. The research was conducted in one cycle, involving 28 students as subjects. Data collection was carried out through evaluation tests (pre-cycle and cycle I) as well as observation of student learning activities. The results of the study showed a significant increase in problem solving ability. The average score of students increased from 36.43 in the pre-cycle to 93.21 in the first cycle, with a t-test of 25.18 and a p< value of 0.001, indicating a high significance. Learning completeness increased from 0% to 100%. The TPS model has been proven to be able to overcome misconceptions, especially through the peer scaffolding process in the "pair" stage, which helps students in identifying variables and choosing the right calculation operations. In addition, there was an increase in students' collaborative skills in terms of expressing opinions and asking questions, with an achievement range between 68% to 75%. The main obstacles faced in the implementation of polling stations are the management of discussion time and class noise. However, this was successfully overcome through the use of timers and Student Worksheets (LKPD) equipped with scaffolding questions. It can be concluded that the TPS model is an innovative and effective approach in improving mathematical problem solving skills contextually, in line with the principles of the Independent Curriculum.

Anemia is a common health problem among adolescent girls, especially in developing countries like Indonesia. This condition is generally caused by insufficient iron intake, an unbalanced diet, and increased iron requirements during growth. Anemia not only impacts physical health but also affects concentration, productivity, and quality of life. Therefore, interventions based on nutrition education and the utilization of local food sources are crucial in sustainable anemia prevention efforts. One potential complementary therapy alternative is the consumption of herbal drinks based on moringa leaves (Moringa oleifera). Moringa leaves are known to be rich in iron, vitamin A, and antioxidants that play a role in red blood cell formation. This community service activity aims to increase the knowledge and skills of adolescent girls in utilizing moringa leaves as a natural source of iron. The target group is grade 10 and 11 female students at SMA Sejahtera Palembang, which was held in June 2025. The activity methods included a nutrition lecture on anemia and the importance of iron, an interactive discussion on the benefits of moringa leaves, and hands-on practice in making herbal moringa drinks (such as moringa leaf tea and moringa juice). The material was delivered using a communicative and participatory approach to actively engage participants. The results of the activity showed an increase in participants' understanding of the causes of anemia, the benefits of moringa leaves, and their willingness to consume herbal drinks as a preventative measure. Most participants also expressed interest in trying to make their own moringa herbal drink at home. This activity is expected to become part of school-based promotional and preventive efforts to address anemia in adolescent girls.

This research explores the influence of customer satisfaction on the financial performance of Perumda Tirtanadi, with a particular focus on the digital service system as a moderating factor. The study is driven by the growing urgency for digital innovation in public service sectors, particularly in the wake of the COVID-19 pandemic, which significantly altered customer engagement patterns. A quantitative method is adopted, employing Partial Least Squares–Structural Equation Modeling (PLS-SEM) using the SmartPLS 4 software to process the collected data. The analysis demonstrates that both customer satisfaction and digital services have independent and significant positive effects on financial outcomes. However, the interaction between these two variables does not show a statistically significant moderating effect. These findings underline the value of digital infrastructure as a strategic internal resource that supports financial growth. Nevertheless, the minimal moderating impact suggests that a portion of customers either lack access or sufficient skills to effectively utilize the available digital platforms. This study adds to the current body of knowledge by examining the interplay between digital transformation and customer satisfaction in shaping financial performance, framed through the Resource-Based View (RBV) theory. The research suggests that improving digital literacy and promoting better adoption of digital tools among customers is essential to fully capitalize on the benefits of technological advancement. Furthermore, it highlights the need for continuous training and support to ensure that all customers can engage with digital services effectively, thereby enhancing overall satisfaction and financial performance. By addressing these gaps, organizations can foster a more inclusive digital environment that benefits both the customers and the service providers.

This study aims to analyze the role of mental health as a moderation variable in the relationship between work facilities and employee job satisfaction. Adequate work facilities are generally thought to be able to increase job satisfaction, but these effects can vary depending on the individual's psychological condition, particularly mental health. This research is motivated by the importance of a holistic approach in human resource management, which includes both physical and psychological aspects of the work environment. The research method used was a quantitative approach with survey techniques to 150 respondents working in the public service sector in urban areas. The data collection instrument was in the form of a closed questionnaire with a Likert scale, and hypothesis testing was carried out through moderation regression analysis using the help of SPSS software. The results of the study show that work facilities have a positive and significant influence on employee job satisfaction. In addition, it was found that mental health played a significant role as a significant moderation variable in the relationship. This means that the influence of work facilities on job satisfaction becomes stronger or weaker depending on the level of mental health possessed by employees. These findings underscore the importance of organizations not only focusing on improving physical work facilities, but also paying attention to and managing employees' mental health as an integral part of strategies to improve well-being and work productivity. Interventions such as counseling programs, work-life balance, and stress management training need to be considered as part of the organization's policies. This research makes a theoretical contribution in enriching the understanding of the role of psychological variables in job satisfaction dynamics, as well as a practical contribution to management in designing a healthier and more productive work environment.

This study aims to analyze in depth the structure of production cost components and determine a reasonable and competitive selling price for shrimp farming in the Venambak Shrimp Farm. The background of this study is the need to determine the cost efficiency and profit potential of shrimp farming activities, so that business actors can make the right decisions and be oriented towards sustainability. The study uses a quantitative descriptive approach with the full costing method to calculate the total production costs, and the cost plus pricing method to determine the selling price. The data used consists of primary data, such as details of operational expenses during one cultivation cycle (six months), as well as secondary data obtained from internal company reports and records. The results of the analysis show that the total production costs incurred in one shrimp cultivation cycle reached Rp16,085,208,000, with a total harvest of 1,000,000 kg. Based on these figures, the cost of goods manufactured (COGS) was obtained at Rp16,085 per kg. In determining the selling price, the company used the cost plus pricing method and set the selling price at Rp80,000 per kg. Thus, the profit margin obtained by the company reached Rp63,915 per kg. Gross profit generated during one cultivation cycle reached Rp63,915,000,000. If cultivation were conducted in two cycles per year, the annual gross profit could potentially increase to Rp127,830,000,000. These findings indicate that with efficient cost management and the right pricing strategy, shrimp farming has significant profit potential. Therefore, intensive and sustainable shrimp farming development at the Venambak Shrimp Farm is highly feasible to improve the competitiveness and welfare of fisheries business actors.
