Travertine is a non-marine carbonate rock precipitated from calcium- and bicarbonate-rich waters, commonly associated with hot springs, streams, and lakes in tectonically active regions. This study presents a systematic literature review of travertine deposit characteristics, encompassing mineralogical composition, geochemical signatures, petrographic textures, morphological types, isotopic properties, biotic–abiotic controls on formation, early diagenesis, and petrophysical implications. The synthesis indicates that travertine is predominantly composed of calcite, with aragonite forming under conditions of elevated temperature, high Mg/Ca ratios, and rapid CO₂ degassing. Travertines display exceptional textural diversity, ranging from abiotic crystalline crusts to microbially mediated fabrics such as shrub, peloidal, and stromatolitic structures. Major morphologies include fissure ridges, mounds, terraces, cascades, and slopes, strongly governed by tectonic setting, topography, hydrology, and substrate geology. Stable isotopes (δ¹³C and δ¹⁸O), strontium isotopes, trace elements, and REE patterns effectively constrain fluid provenance and distinguish thermogene from meteogene travertines. Microbial activity plays a crucial role in biomineralization, influencing precipitation rates, crystal morphology, and lamination patterns. Early diagenetic processes occurring during active deposition may significantly modify primary fabrics and geochemical signals. Travertine petrophysical properties exhibit distinctive porosity–velocity relationships, making them valuable analogues for subsurface carbonate reservoirs. This review highlights that travertines record complex interactions among physical, chemical, biological, and geological processes and hold significant value for paleoenvironmental reconstruction and carbonate reservoir studies.

The rapid development of digital technology has transformed patterns of communication, learning processes, and the ways believers access religious information in daily life. While this transformation provides easier access to information, it also fosters an instant culture characterized by fast, brief, and less reflective information consumption. This condition poses significant challenges for the Church, particularly in faith formation, as it may weaken the depth of believers’ understanding of faith. This study aims to examine the role of literate catechesis as a response to the instant culture of the digital era, while also exploring the opportunities offered by digital media in faith proclamation. This research employs a qualitative approach using a literature review method based on relevant academic sources. The findings indicate that literate catechesis plays a crucial role in fostering mature faith through reading, reflection, and critical thinking processes, enabling believers not only to consume information but also to internalize and live out their faith more deeply. On the other hand, digital media offers significant opportunities to develop catechesis that is broader, more participatory, and contextually relevant. Integrating reflective depth with creative digital approaches is essential to ensure that faith formation remains both meaningful and relevant within an increasingly instant-oriented culture.

This research is motivated by the increasing role of Artificial Intelligence (AI) in organizational transformation and the crucial function of leadership in ensuring its successful implementation. The primary objective of this study is to analyze the relationship between leadership, AI integration, and organizational performance, as well as to identify various challenges and supporting factors in the process. This study employs a systematic literature review (SLR) method by examining 30 relevant, reputable scientific articles from the Scopus and Google Scholar databases within the 2020–2026 timeframe through selection, evaluation, and thematic synthesis processes. The results indicate that AI integration significantly contributes to improving operational efficiency, data-driven decision-making quality, and organizational innovation. However, this success heavily depends on the role of adaptive, transformational, and digitally-oriented leadership capable of steering the technological vision. Conversely, major challenges were identified, such as employee resistance, limited digital competencies, and ethical issues surrounding data privacy. This study contributes to strengthening the conceptual understanding of leadership's role as a bridge between technology and organizational performance, while offering practical implications for management in designing effective, inclusive, and sustainable digital transformation strategies.

This research is motivated by the phenomenon of decreasing number of customers at Emdee Easy Beauty Clinic Batam, which indicates the need for an evaluation of marketing strategies. The purpose of this study is to analyze the influence of price, promotion, brand image, and product quality on consumer satisfaction. The research method used is quantitative associative with a sample of 91 respondents taken using simple random sampling technique. Data were collected through questionnaires and analyzed using multiple linear regression. The results showed that simultaneously, price, promotion, brand image, and product quality had a significant effect on consumer satisfaction (F count 14.111 > F table 2.47). Partially, the variables of price, promotion, and brand image have a positive and significant influence, but product quality does not have a significant effect on consumer satisfaction in this study. The implication of these findings is that clinic management needs to prioritize competitive pricing strategies, strengthen promotional activities, and maintain a positive brand image to sustain and increase customer satisfaction.

This research is motivated by the vital role of clean water services and the need to optimize operational revenue at BLUD UPT Water Supply Management in Batam City. The study aims to analyze the influence of willingness to pay, ability to pay, and payment awareness on BLUD revenue achievement. A quantitative associative approach was employed, involving a population of 29,047 customers. A sample of 100 respondents was determined using the Slovin formula, and data were analyzed via multiple linear regression using SPSS software. The results indicate that, simultaneously, all three independent variables significantly affect revenue achievement with an F-value of 56.825 and a significance of 0.000. Partially, willingness to pay (t=8.279), ability to pay (t=11.020), and payment awareness (t=10.435) also exert a significant influence. These findings imply that higher community payment behavior directly increases institutional revenue. It is recommended that BLUD improves service quality and payment socialization to ensure sustainable revenue achievement.

Public facilities play an important role in supporting community activities, especially in sports and social interaction. However, inadequate maintenance can reduce their functionality and user comfort. This study aims to improve the function of public facilities through the revitalization of a badminton court area at the Technical Implementation Unit for Road and Bridge Management in Surabaya, making it more feasible, safe, and comfortable for use. The study employs a quantitative descriptive approach combined with Participatory Action Research (PAR), with data collected through direct observation of facility conditions before and after revitalization. The results show a significant improvement in the quality of infrastructure, both in physical condition and environmental comfort. The revitalized court supports better sports activities and increases user participation. These findings indicate that revitalization not only enhances facility quality but also promotes greater utilization, improved social interaction, and a more productive environment, demonstrating its effectiveness in optimizing public facility functions.

Using Non Performing Financing (NPF) as a moderating variable, this study looks at how profit sharing and profit margin financing affect the effectiveness and stability of Islamic banks in Indonesia. The primary topic discussed is how various Islamic financing arrangements affect the operational effectiveness and financial stability of banks, as well as whether credit risk enhances or diminishes these connections. This study aims to examine the direct impacts of financing modalities as well as the moderating influence of NPF on the performance of Islamic banks. Based on secondary data from eight Islamic banks in Indonesia between 2018-2024, this study employs a quantitative methodology using panel data regression and Moderated Regression Analysis (MRA). The findings indicate that while profit margin financing has no discernible impact on efficiency, profit sharing financing has a favorable and considerable impact. Profit margin financing has a negative and negligible impact on stability, whereas profit sharing financing has a positive but negligible impact. Additionally, by changing the direction of influence, NPF significantly moderates the association between profit sharing financing and both efficiency and stability. However, it does not significantly moderate the effect of profit margin financing on efficiency, but it does on stability. In summary, the effectiveness of Islamic financing is heavily reliant on risk management, especially credit risk control, where NPF is a key factor in evaluating whether financing can improve stability and efficiency in Islamic banks.

This article examines umpasa as the determinant of the validity of the Mangalahat Horbo ritual and as a vehicle for transmitting the cultural values of the Batak Toba people from an anthropolinguistic perspective. Mangalahat Horbo is a buffalo sacrifice ritual that functions simultaneously as a cosmological, political, and linguistic event. This study employs a descriptive qualitative approach using three theoretical frameworks: Dell Hymes' (1974) SPEAKING model to analyze the ritual as a speech event, Roland Barthes' (1968) semiotics to dissect the denotative and connotative meanings of umpasa, and Kluckhohn's (1953) theory of cultural values and Sibarani's (2014) local wisdom theory to identify embedded cultural values. The findings reveal that umpasa operates on three simultaneous layers of meaning: pragmatic-performative, social-hierarchical, and cosmological-ecological. Umpasa is not merely an aesthetic ornament but a constitutive element of the ritual that shapes the social and cosmological reality of the Bius community. Eight cultural values are identified: communicative courtesy, adat knowledge transmission, self-restraint, collective responsibility, cultural preservation, cosmological reciprocity, distributive justice, and ecological harmony. This study affirms the urgency of anthropolinguistic documentation of Mangalahat Horbo before the Parhata masters of umpasa diminish further.

The rapid development of technology accompanied by increasing industrial competition makes human resources a determining factor for organizational success. In this context, job satisfaction is an important indicator because it is closely related to individual welfare and employee productivity. This study aims to analyze the influence of work life balance, burnout, and motivation on the job satisfaction of employees in the production department of PG Kedawoeng PT Sinergi Gula Nusantara, Pasuruan Regency. This study uses a quantitative approach. The study population includes all permanent employees of the production department as many as 64 people, with census sampling techniques so that the entire population is used as respondents. Data analysis was carried out using multiple linear regression. The results showed that simultaneously work life balance, burnout, and motivation had a significant effect on job satisfaction (p=0.000; Adjusted R²=81.1%). Partially, work-life balance had no significant effect (p=0.386), burnout had a negative but insignificant effect (p=0.082), while motivation had a significant positive effect on job satisfaction (p=0.000). The motivation variable was the most dominant factor with a contribution of 76.1%, followed by burnout at 6.0% and work life balance at 0.6%.

This study aims to examine the impact of academic burnout on students’ mental health in the context of hybrid learning through a literature review approach. The rapid transformation of learning systems in higher education, particularly the integration of online and offline methods, has increased academic demands and adaptation challenges for students. This condition potentially triggers academic burnout, which is characterized by emotional exhaustion, depersonalization, and decreased academic achievement. This research employs a literature review method by analyzing relevant scientific articles published between 2019-2025 obtained from indexed national journals and open-access sources. The findings indicate that academic burnout is still commonly experienced by students, generally at a moderate level, and has a significant impact on mental health, including increased stress, emotional fatigue, and decreased academic performance. The study also identifies several influencing factors, including internal factors such as self-efficacy and hardiness, as well as external factors such as social support, learning environment, and academic workload. Furthermore, technological developments, particularly Artificial Intelligence, have the potential to be utilized as an early detection and prevention tool for academic burnout. This study implies the importance of developing adaptive learning strategies and psychological interventions to support students’ well-being in hybrid learning environments.

The use of building materials plays a crucial role in determining the quality of the built environment, particularly in the context of row housing in densely populated urban areas. This study aims to evaluate the types of materials used in the construction of row housing in Cemara Asri, Medan, with a focus on sustainability and environmental friendliness criteria. The methods employed include direct site surveys and literature studies related to the characteristics of both interior and exterior materials applied to housing units. The research findings indicate that most of the materials used—such as red bricks, ceramic tiles, clay roof tiles, and concrete ventilation blocks—possess good energy efficiency and durability potential. However, they do not fully meet sustainability standards in terms of production processes and waste management. The study also found that residents' awareness of environmentally friendly material selection remains limited, and the procurement of materials tends to follow local availability and economic considerations. These findings are expected to serve as a foundation for improving environmentally friendly material planning in row housing developments in other urban areas.

This study aimsmto examineiin depthvthe perspective of information technology law and human rights on the phenomenon of political buzzers on social media within the context of digital development in the era of globalization. This research is motivated by the rapid advancement of information technology, which has brought significant changes in various aspects of society, including the political sphere that increasingly utilizes social media as a means of communication and information dissemination. The phenomenon of political buzzers has become a controversial issue, particularly during election periods, as it is often associated with the spread of inaccurate information, defamation, hate speech, and the manipulation of public opinion that may harm society and disrupt social stability. This study employs a normative legal research method using statutory and conceptual approaches. The results indicate that political buzzers generally operate under the justification of freedom of expression as part of human rights. However, such freedom is not absolute and must be limited to prevent violations of others' rights and to maintain public order. In this regard, information technology law in Indonesia, particularly through regulations governing digital activities, plays an important role in controlling deviant buzzer practices. Nevertheless, the absence of specific regulations explicitly governing political buzzers has resulted in less optimal law enforcement. Therefore, strengthening regulations and increasing public awareness in the wise use of social media are necessary to create a healthy, responsible, and sustainable digital ecosystem.

Flood disasters have repeatedly affected Aceh Tamiang Regency for over fifteen years, causing significant material and socio-cultural losses. This study aims to examine the social response of the community through a literature review approach, using Jurgen Habermas's Communicative Action Theory as the analytical framework. Data were collected systematically from national journal articles, scientific proceedings, and academic reports related to flood mitigation and community social response in Aceh Tamiang. Data analysis was conducted using content analysis and thematic analysis techniques. The findings reveal that the community's response is primarily driven by local solidarity rooted in cultural values and local wisdom such as hadih maja. In Habermasian terms, this social response reflects the lifeworld domain, manifesting in voluntary collective action. However, a structural tension exists between the government's top-down system and the community's communicative rationality. Effective disaster mitigation requires the development of participatory public spaces that bridge the system and lifeworld, enabling the transformation from instrumental action to communicative action, thereby strengthening collective resilience against flood disasters.

The development of social media in the digital era has significantly changed children’s social interaction patterns. Besides providing benefits such as easier access to information and opportunities for creativity, social media also brings negative impacts on children’s psychological, social, and moral development. This study aims to analyze the restriction of social media use among children from the perspective of Jürgen Habermas, especially regarding the concepts of the public sphere, communicative rationality, and the colonization of the lifeworld. This research uses a literature study method with a qualitative descriptive approach through the collection and analysis of relevant scientific articles. Data validity was strengthened through inclusion and exclusion criteria as well as source triangulation. The findings indicate that social media use among children has an ambivalent impact. Positive effects can emerge when there is strong parental supervision, while weak supervision increases the risk of exposure to harmful content, psychological problems, and reduced quality of social interaction. Restricting social media use through time regulation, content control, and digital education is considered important for protecting children’s development. From Habermas’s perspective, children are vulnerable in the digital public sphere because of their limited communicative rationality. Therefore, restrictions are viewed as efforts to protect children’s values and rationality from distortion by the digital media system.

Employee engagement is critical to organizational performance, employee well-being, and long-term sustainability. In hybrid work contexts, generational differences have become increasingly evident, particularly between Generation Y and Generation Z employees. Generation Y tends to emphasize work–life balance, career development, and meaningful collaboration, while Generation Z prioritizes flexibility, job security, digital integration, and the use of technology in the workplace. This study adopts a systematic literature review (SLR) approach by synthesizing findings from various peer-reviewed studies related to employee engagement and hybrid work practices across generations. The review focuses on identifying key factors that influence employee engagement in modern work environments. The results indicate that hybrid work can significantly enhance employee engagement when organizations provide flexibility, autonomy, adequate technological support, professional development opportunities, and fair reward systems. In addition, supportive organizational culture and effective leadership are important in maintaining employee motivation and commitment. However, differences in generational expectations require organizations to implement adaptive managerial strategies, including flexible work policies, personalized communication approaches, and inclusive leadership practices to strengthen employee engagement across different generations in hybrid work settings.

The development of Artificial Intelligence (AI) has transformed how business organizations manage operations, process information, and make strategic decisions, thereby creating a need for leadership patterns that are more adaptive, visionary, and responsive to digital transformation.

The findings show that AI Leadership represents a modern form of leadership that emphasizes not only technological understanding but also the ability of leaders to direct organizational change, foster data-driven decision making, manage collaboration between humans and technology, and implement responsible AI governance. The study also finds that the main strategies required by leaders in the AI era include strengthening digital literacy, developing adaptive managerial capabilities, enhancing human–AI collaboration, and integrating ethical principles into technology implementation. This article contributes conceptually by reinforcing AI Leadership as a leadership framework that is highly relevant to modern organizations and offers practical implications for the development of business leadership in the era of digital transformation.

Laparotomy is a major surgical procedure associated with a high risk of acute postoperative pain. According to Gan (2017), if pain is not properly managed, it can progress to chronic pain. (Toro et al., 2018) reported that severe pain on the first postoperative day is still commonly found in laparotomy patients, while (Small & Laycock, 2020) indicated that moderate to severe pain within the first 24 hours following major surgery remains a significant clinical issue. This study aims to evaluate the effectiveness of pharmacological pain management following laparotomy under general anesthesia, specifically to identify the types of opioid analgesics used, analyze their effectiveness in reducing pain intensity, identify side effects, and examine administration techniques and routes. This study employed a Systematic Literature Review (SLR) method following the PRISMA guidelines. Literature searches were conducted in the PubMed, ScienceDirect, and SpringerLink databases covering the years 2015–2026. The included studies comprised randomized controlled trials (RCTs), cohort studies, and retrospective studies addressing opioid pharmacological pain management in adult patients following laparotomy under general anesthesia. Study quality assessment was performed using the Joanna Briggs Institute (JBI) instrument. A total of 11 studies met the inclusion criteria. The results of the systematic literature review indicate that opioids are effective in reducing postoperative pain following laparotomy under general anesthesia. The most commonly used opioids are morphine, fentanyl, and oxycodone. Of all the opioids reviewed, oxycodone provided the best pain control, while intrathecal morphine was most effective in reducing the need for supplemental opioids during the early postoperative period. Other opioids, such as extended-release dinalbuphine sebacate and tegileridine, are also effective, but the number of studies is still limited. The most common side effects are nausea, vomiting, pruritus, sedation, and dizziness. Pharmacological pain management using opioids is effective in reducing the intensity of postoperative pain following laparotomy under general anesthesia. Morphine, fentanyl, and oxycodone are the most commonly used opioids. Oxycodone and intrathecal morphine have shown good results in improving pain control and reducing the need for supplemental opioids. The selection of opioid type, dosage, and administration technique must be tailored to the patient’s clinical condition to achieve optimal analgesia with minimal side effects.

The development of artificial intelligence (AI) has transformed organizational landscapes and driven fundamental changes in leadership practices and strategic management. This article aims to critically examine AI-based leadership by highlighting its opportunities, risks, and implications for strategic management. The study employs a qualitative literature-based approach using an integrative literature review strategy. The data consist of secondary scholarly literature relevant to AI, leadership, governance, innovation, and strategic management, which were analyzed through qualitative thematic analysis and conceptual content analysis. The findings show that AI-based leadership creates opportunities in the form of improved decision quality, faster strategic analysis, operational efficiency, stronger innovation, and enhanced organizational agility. However, AI integration also presents risks, including algorithmic bias, limited decision transparency, technological dependency, accountability challenges, and ethical concerns. This study confirms that AI does not fully replace human leaders; rather, it fosters a hybrid leadership model that requires technical, adaptive, transformational, and ethical capabilities. The study implies that the effectiveness of AI-based leadership depends on responsible governance, organizational cultural readiness, and balanced human–machine collaboration in supporting strategic management.

Irregular sleep patterns are a common issue experienced by university students and are often considered a normal part of academic life. However, such conditions can have negative effects on students’ learning concentration and cognitive function. Poor sleep patterns are generally influenced by various factors, including high academic workload, habitual late-night activities, poor time management, and excessive use of electronic devices at night. This study aims to examine the relationship between sleep patterns and students’ learning concentration, identify factors contributing to irregular sleep patterns, and analyze constraints as well as propose solutions to improve sleep quality in order to enhance learning concentration. The method used in this scientific paper is a literature review, which involves examining relevant scientific sources such as research journals and academic literature related to sleep patterns and students’ learning concentration. The results of the review indicate that students with poor sleep patterns tend to experience physical fatigue, decreased immune function, cognitive impairment, and difficulties in maintaining focus and concentration during the learning process. In the long term, these conditions have the potential to reduce academic achievement and learning motivation. Therefore, it can be concluded that effective time management, limiting the use of electronic devices before bedtime, creating a conducive sleep environment, and support from universities through health education play an important role in improving students’ sleep patterns. With regular and high-quality sleep, students’ learning concentration is expected to improve, allowing the learning process and academic achievement to proceed optimally.

The issue of forest degradation caused by illegal logging in Indonesia poses a serious threat to ecosystem balance and the survival of wildlife. This condition highlights the need for effective visual communication media to deliver environmental education messages in a communicative and easily understandable manner. This study aims to design a 2D educational animation that illustrates the impact of illegal logging on forest ecosystems from the perspective of an endemic animal, the surili. The method used is a qualitative approach with animation production stages consisting of pre-production, production, and post-production. The pre-production stage includes idea development, research, scriptwriting, storyboard creation, and visual design. The production stage involves the creation of visual assets, backgrounds, and animation processes to construct the storyline. The post-production stage includes visual editing, audio integration, and rendering as the final output. The result of this study is a 2D animation entitled “Jaga Lingkungan Hindari Kepunahan Alam,” which presents a structured narrative to effectively convey educational messages. The implications of this work indicate that animation as an educational medium can enhance public awareness of the impacts of illegal logging and emphasize that forest destruction affects not only wildlife but also humans as part of the ecosystem.
