The global ecological crisis is not only a scientific issue but also reflects the decline of human moral and spiritual awareness toward nature. This study aims to examine the acculturation approach of Islam Nusantara in Islamic Religious Education (PAI) learning as an effort to foster students’ ecological awareness. The research employed a qualitative library research method using various relevant sources, including books, national and international journal articles, and educational policy documents. Data analysis was conducted through data reduction, thematic presentation, and interpretive-analytical conclusion drawing. The findings indicate that Islam Nusantara, as a product of the acculturation between universal Islamic values and local Nusantara wisdom, contains various ecological traditions such as sasi, subak, and hutan larangan (forbidden forests), which can be contextually integrated into PAI learning. The developed learning model includes the use of local wisdom as learning resources, participatory project-based learning methods, and thematic Qur’anic interpretation related to environmental issues. The ecotheological approach of Islam Nusantara is considered effective in connecting religious teachings with students’ ecological realities, thereby fostering a religious-ecological character that views environmental preservation as part of worship. Although challenges remain in theological, pedagogical, and institutional aspects, this approach contributes strategically to shaping environmentally responsible Muslim generations.

The transition from paper-based to Computer-Based Test (CBT) in the Academic Potential Test (TPA) for state university entrance selections has significantly transformed the educational assessment landscape. This conceptual study aims to evaluate the instruments of CBT-based TPA, focusing on validity, reliability, fairness, and technological infrastructure constraints. Employing a systematic literature review approach, this research synthesizes various foundational theories of educational measurement, specifically Item Response Theory (IRT) and Computerized Adaptive Testing (CAT), alongside contemporary empirical findings from the last five years. The findings indicate that while CBT offers enhanced administrative efficiency and rapid grading, the validity of the instruments is frequently challenged by item exposure and the diverse digital literacy levels of test-takers. Furthermore, infrastructural disparities among regions pose a significant threat to testing fairness. The implication of this study suggests the urgent need for a dynamic item bank generation system and the implementation of adaptive testing to mitigate cheating and ensure equitable assessment. Future educational policies must bridge the digital divide before uniformly mandating CBT. Ultimately, this review provides a comprehensive framework for test developers to refine CBT TPA instruments, ensuring they genuinely measure academic potential rather than technological proficiency.

This study aims to develop a Strategic Learning Enabler model by reconfiguring the role of Information and Communication Technology (ICT) units to enhance Generation Z student productivity in digital higher education. The research is motivated by the gap between digital transformation demands and the predominantly technical-operational role of ICT units. Using a quantitative explanatory design, this study examines the causal relationships among ICT role reconfiguration, adaptive learning systems, and student productivity. Data were collected through questionnaires distributed to Generation Z students engaged in digital learning environments and analyzed using Structural Equation Modeling (SEM). The findings indicate that Generation Z students exhibit high responsiveness to structured tasks but lack continuity in learning activities due to weak self-regulated learning. The study also reveals that adaptive learning systems significantly mediate the relationship between ICT transformation and student productivity. The proposed model emphasizes digital governance, learning analytics, and micro-tasking structures as key components in building sustainable academic productivity. This research contributes both theoretically and practically by offering an institutional framework for digital learning transformation in higher education.

The rise of the digital age has brought significant changes to leadership dynamics and leadership development patterns within the context of Christian ministry. This paper addresses the critical issue of leadership succession failure, which is driven by a generational gap between senior leaders and young leaders-in-training, as well as the underutilization of technology in the mentoring process. Using a descriptive qualitative approach through literature review, state-of-the-art analysis, and theological synthesis, this study assesses the relevance and effectiveness of the multiplicative leadership model as a solution to the leadership succession problem. The analysis reveals that multiplicative leadership—which emphasizes discipleship, intensive mentoring, delegation of responsibility, and intergenerational collaboration—can bridge the generational gap while accelerating the multiplication of leaders in the digital age. The integration of digital technologies, such as virtual mentoring, digital training modules, and collaborative media, has proven capable of expanding the impact of the leadership development process and enhancing relational closeness between generations. This paper concludes that the multiplicative leadership model is a strategic and theological approach aligned with the biblical mandate to produce leaders capable of developing other leaders, and is relevant for addressing the challenges of contemporary Christian leadership.

Entering the third decade of the 21st century, the church faces the urgency of redefining its existence amidst the shift to a digital ecosystem. This research aims to analyze the synergy between church management and transformational leadership toward the effectiveness of leader multiplication in the Digital 4.0 era. Using a qualitative method with a descriptive-analytical approach through library research, this study explores the integration of modern management theories and theological principles. The findings indicate that church management serves as a vital infrastructure providing operational stability, while transformational leadership acts as a catalyst for innovation and behavioral change in facing VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) conditions. The synergy between these two elements creates a “Digital Shepherding” model, where the digital space is transformed into a theological medium for character formation and spiritual transmission. The study concludes that the effectiveness of leader multiplication is determined by a shift from person-centered leadership to a system-inspired approach that integrates digital capabilities with biblical integrity. Strategic implications suggest that churches must adopt a digital mindset and establish digital leadership laboratories to ensure the sustainability of their mission among Generation Z.

The phenomenon of emotional healing has become increasingly prominent in popular culture as the younger generation experiences increasing loss, emotional exhaustion, and numbness. Popular music serves as a medium of expression, representing these emotional dynamics through poetic language and symbolic structures. This study aims to analyze the emotional representation of healing in Umay Shahab's song "Perayaan Mati Rasa" using Roland Barthes's semiotic approach. The research method used is descriptive qualitative, analyzing three layers of meaning: denotation, connotation, and myth, through breaking down the lyrics into several lexicons and reading signs. The results show that (1) denotatively, the lyrics construct an emotional arc from inner tension to self-contemplation; (2) connotatively, the use of diction and imagery represents vulnerability, resilience, and emotional reflection; and (3) at the mythical level, the song constructs release as a form of emotional maturity and loss as a process of identity formation. Thus, this song functions as a cultural representation in interpreting the process of emotional healing in popular culture.

This study aims to examine the gastronomy of the traditional culinary dish Ayam Napinadar as part of Batak cultural identity, covering aspects of history, ingredients, processing techniques, cultural values, and preservation challenges. The background of this research is based on the importance of maintaining the sustainability of traditional cuisine amid modernization and changes in consumption patterns. The method used is a qualitative approach through in-depth interviews with three informants, namely an MSME (Micro, Small, and Medium Eterprises) practitioner, a traditional leader, and a consumer. The results show that Ayam Napinadar has a unique characteristic in the use of andaliman and blood (gota) as its distinctive flavor. Traditionally, the cooking process involves grilling over firewood to produce a characteristic smoky aroma, although it has now shifted to more practical methods without altering the original recipe. From a cultural perspective, Ayam Napinadar holds symbolic meaning as an expression of prayers, blessings, and joy in various Batak traditional ceremonies. However, there are challenges in its preservation, such as the declining participation of younger generations in traditional activities and the increasing influence of modern foods. In conclusion, Ayam Napinadar functions not only as food but also as a medium for preserving cultural values and ethnic identity. This study provides benefits as a basis for developing gastronomic tourism and strategies for preserving traditional cuisine through education, collaboration, and the use of modern promotional media.

The determination of a minimum marriage age is a central issue in Indonesian family law and Islamic legal discourse, particularly regarding the prevention of health, social, and psychological risks associated with child marriage. This study analyzes the alignment between the legal requirement of a minimum age of 19, as stipulated in Law No. 16 of 2019 and Constitutional Court Decision No. 22/PUU-XV/2017, and the framework of maqāṣid sharī‘ah, especially the hierarchical structure of dharuriyyāt, ḥājiyyāt, and taḥsīniyyāt. Employing a normative juridical method supported by extensive literature review, this research examines statutory regulations, classical and contemporary Islamic legal sources, works on maqāṣid, and empirical data from national and international institutions. The findings demonstrate that the minimum age of 19 substantively accords with maqāṣid sharī‘ah: at the dharuriyyāt level, it safeguards life, intellect, and lineage from medical, psychological, and social harm; at the ḥājiyyāt level, it prevents economic hardship, emotional instability, and the inability of young couples to assume household roles; and at the taḥsīniyyāt level, it preserves human dignity, ethical conduct, and the sanctity of marriage. Consequently, the regulation is not a departure from classical Islamic jurisprudence but rather an implementation of public interest (maṣlaḥah) adapted to contemporary societal realities. This study affirms that integrating maqasid-based reasoning into public policy strengthens the protection of families and future generations in Indonesia.

This study aims to analyze the comparison of the impact of financial and non-financial compensation effectiveness on turnover intention among Generation Z employees. The high turnover rates within Generation Z, despite receiving adequate financial compensation, indicate a shift in their preferences regarding the workforce. Generation Z tends to seek more than just financial compensation, such as flexibility, a supportive work environment, and opportunities for growth. The method used in this study is a literature review, analyzing various relevant scholarly journals related to strategic compensation, Generation Z characteristics, and turnover intention. The research findings show that non-financial compensation has a more significant impact in reducing turnover intention among Generation Z compared to financial compensation. Therefore, companies need to focus on aspects such as work-life balance, career development opportunities, and an inclusive and supportive work culture. These findings provide valuable insights that companies should adopt a more holistic reward approach through the total rewards concept, which includes both financial and non-financial compensation, in order to enhance loyalty and retention of Generation Z employees in the long term.

The digital era has fundamentally revolutionized human interaction and information processing, particularly for Generation Z as digital natives. This research aims to identify the characteristics of digital information consumed by Generation Z and evaluate their long-term memory (LTM) capacity in the digital age. Using a Systematic Literature Review (SLR) method with a qualitative approach, 15 relevant studies published between 2021 and 2026 were analyzed from databases such as Scopus, Google Scholar, and ScienceDirect. The findings indicate that digital information characteristics—which are often "bite-sized," visual, and rapidly consumed—tend to encourage shallow encoding and digital amnesia. However, the study also found a dual impact: while high cognitive load and constant multitasking can hinder memory consolidation, structured digital use and interactive learning modules can significantly enhance memory retention. These results imply that optimal cognitive function in the digital era highly depends on digital literacy and effective information management strategies to balance technological use with natural cognitive sharpness.

Therefore, strengthening household waste separation, improving operational management, and increasing community participation are recommended to enhance waste reduction and support sustainable urban waste management systems.

Generators are one of the important auxiliary aircraft needed on ships for power generation. During the operation of a diesel generator, continuous rotation occurs resulting in friction and erosion of the moving parts. The supporting factor for the smooth running of a diesel engine is a lubrication system that is supported by good lubricating oil quality, besides that it also needs to be supported by an adequate and good cooling system. The use of lubricants is one of the most important factors to ensure the performance of diesel engines. The lubricant is in charge of maintaining the condition of the engine so that it remains stable. This study aims to analyze the effect of using lubricating oil beyond the operating hours limit on engine heat. Furthermore, it also discusses steps to ensure diesel engine temperatures remain normal. This research was carried out during the practice of sailing on a ship for approximately one year. This study uses a descriptive quantitative research method. The primary data obtained directly utilizes observation methods, and documentation. Secondary data was obtained from existing articles and journals. The data analysis techniques used are descriptive analysis and inferential analysis. The results of this study show that the working hours of lubricating oil use have a significant influence on the increase in the temperature of diesel generator engines as evidenced by hypothesis tests on two engine units, namely AE1 and AE2. In the AE1 unit, a t-value of 18.467 with a significance of 0.000 was obtained, while in AE2 the t-value was 14.289 with a significance of 0.000. The significance value in both units is less than 0.05 so it can be concluded that the working hours of lubricated oil have a significant influence on the temperature of the genarato diesel engine on the ship.

This research aims to design and develop a prototype wave power plant that utilizes the vertical motion of a buoy as a source of mechanical energy, which is then converted into electrical energy using a recoil starter mechanism. The system is designed to be installed at the stern of a prototype ship. The vertical movement of the buoy caused by ocean waves is transmitted to the recoil starter through a drive rope, producing a stable one-way rotational motion. This rotation is further transmitted to a gearbox to increase rotational speed before driving a DC generator. The electrical energy generated is stored in a 12 VDC battery, supported by a buck–booster converter to stabilize the output voltage. This study employs an experimental engineering approach to evaluate system performance based on empirical test data. The main components of the system include a buoy as a wave energy collector, a recoil starter as the initial rotating mechanism, a DC generator as the electrical energy producer, a buck–booster converter as a voltage regulator, a 12 VDC battery as an energy storage unit, and a monitoring system based on an ESP32 microcontroller integrated with a PZEM-017 sensor. Experimental results show that the recoil starter operates effectively in driving the generator under both no- load and buoy-loaded conditions. Increases in generator rotational speed are directly proportional to increases in output voltage and current. The PZEM-017 sensor demonstrates a high level of measurement accuracy, approaching 100% when compared with a multimeter. Overall, the proposed wave power generation system functions reliably and shows potential for further development as a small-scale alternative renewable energy source.

The increasing demand for electrical energy and the limited availability of fossil fuels have driven the development of renewable energy sources, including marine current energy, which remains underutilized in coastal and remote maritime regions. This study presents the design and realization of a small-scale marine current power generation prototype using a horizontal axis propeller turbine with a NACA S814 blade profile and analyzes the effect of turbine rotational speed on electrical power output. The system converts marine current kinetic energy into mechanical energy through turbine rotation and subsequently into DC electrical energy using a generator, which is stabilized by a Buck–Boost Converter and Maximum Power Point Tracking (MPPT) for charging a 12 VDC battery. Real-time monitoring of electrical and mechanical parameters is implemented using an Internet of Things (IoT)–based system comprising an ESP32 microcontroller, a PZEM-017 sensor, and an RPM sensor. Experimental results demonstrate a positive correlation between water flow rate, turbine rotational speed, and generator output voltage. The system begins operating at a minimum flow rate of 35.2 L/s at 56 RPM, producing 0.2 V, while optimal performance is achieved at 45.3 L/s and 516 RPM, generating up to 13.3 V. These results indicate that the proposed prototype is a viable alternative renewable energy source for marine applications.

Kampar Kiri District faces challenges in the form of low public understanding of anti-corruption values, which has an impact on hampering the development of the people's economy and transparency of local governance. This Community Service (PKM) activity aims to increase critical public awareness and internalize the value of integrity in sharia-based economic activities. The implementation method is carried out through a participatory approach that includes socialization, education on moral-religious values, and interactive discussions.

The results of the service show a positive response from the local government and high enthusiasm from the younger generation in maintaining integrity. Through the involvement of expert speakers from the Riau Anti-Corruption Counseling Forum and the Kampar Inspectorate, the community gained a comprehensive understanding of the dangers of corruption from a legal and religious perspective. This program has succeeded in laying the foundation for the formation of an honest, transparent, and accountable social ecosystem to realize a blessed community economy.

Religious culture that is still quite strong in the community is an important capital in the implementation of youth development programs. However, the influence of social media, promiscuity, and the lack of religious activities that are attractive to the younger generation have led to a decrease in adolescents' interest in religious activities in mosques. Therefore, this research aims to form the character of discipline, responsibility, and cooperation in the group through Islamic hadrah art activities. This study uses the Asset Based Community Development (ABCD) method, which is a community empowerment approach that focuses on the strengths and potentials possessed by the community, not on existing shortcomings or problems. In this approach, the community is invited to identify various assets they have, such as human resources, local institutions, cultural values, and social networks that can be used to overcome the problems they face. The results of the study showed that the adolescent participants experienced improved skills in playing hadrah and understanding of religious values. In addition, there has been a change in behavior towards being more disciplined, active, and caring for religious activities in the mosque environment.
