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.

Advances in digital technology have transformed the paradigm of faith proclamation, requiring the Church to optimize social media as a relevant catechetical instrument. This study aims to examine how the use of the TikTok platform can be optimized as an effective means of creative catechesis in connecting complex faith teachings for people in the digital era. The research method used is descriptive qualitative with a literature study technique, where data is collected from various scientific literature, Church documents, and relevant library sources. The research findings indicate that TikTok is an effective digital space for catechesis because it is supported by attractive audio-visual features, interactive features such as stitches and comments that enable two-way dialogue, and an algorithmic system that expands the reach of proclamation. The strategy of catechesis through short videos has proven to be able to change the perception of faith teaching that has become rigid to a more personal spiritual experience that is easily understood by all levels of society, especially the younger generation. The implications of this study emphasize the need for the Church to consistently adapt to digital culture and increase content creativity to ensure the continuity of inclusive evangelization amidst the dynamics of modern developments.

Knowledge should not only make human beings intellectually capable, but also guide them to understand the meaning and direction of life. However, in modern education, knowledge is often reduced to an instrument for obtaining grades, degrees, employment, and material success. This condition indicates a crisis of meaning in education, where knowledge grows rapidly but is not always followed by moral awareness and spiritual maturity. This article examines the Philosophy of Unity of Sciences as an alternative paradigm to restore the meaning of knowledge in modern education. This study uses library research with a descriptive-critical approach. The primary sources include the Qur’an, Hadith, Al-Ghazali’s Iḥyā’ ‘Ulūm Al-Dīn, Syed Muhammad Naquib Al-Attas’ Islam and Secularism, and the Javanese ethical text Serat Wedhatama. This article is also strengthened by the thoughts of Muslim scholars such as Al-Kindi, Al-Farabi, Ibn Sina, Al-Biruni, Ibn Al-Haytham, Al-Khawarizmi, and Ibn Khaldun. The result of this study shows that the Philosophy of Unity of Sciences views all knowledge as originating from Allah. Therefore, religious knowledge and general knowledge should not be separated or opposed to each other. Both should work together to form human beings who are faithful, rational, ethical, and responsible. In this sense, knowledge can be understood as “a way home”, namely a way to return to God, to the self, to humanity, and to nature.

This study aims to analyze student time management and its relationship to academic productivity among students in the Economics Education Study Program, Jambi University, class of 2023. This study used a qualitative approach with data collection techniques through in-depth interviews with a number of students selected purposively. The results showed that most students were unable to manage their time optimally, as reflected in the habit of procrastinating on assignments, a lack of structured planning, and an imbalance between academic and non-academic activities. Many students tended to work on assignments only close to the deadline and found it difficult to maintain a consistent schedule. Conversely, students who had a more structured time plan, such as compiling daily to-do lists and setting priorities, demonstrated better academic productivity. They were able to complete assignments on time, produce better quality work, and were more active in the learning process and class discussions. This study confirms that effective time management plays a crucial role in improving student academic productivity, both in terms of the quality of work results and the timeliness of assignment completion. Therefore, more intensive efforts are needed to increase students' awareness and skills in time management, so they can achieve optimal learning outcomes, reduce stress levels, and face academic demands more efficiently. In this context, developing good time management strategies is essential to help students maximize their academic potential.

This study examines the role of halal tourism in enhancing destination competitiveness and strengthening the Islamic economy within the tourism sector. This research employs a systematic literature review to synthesize findings from relevant academic sources. The results indicate that halal tourism contributes significantly to destination competitiveness by increasing tourist arrivals and encouraging product diversification. In addition, it supports the development of micro, small, and medium enterprises (MSMEs) and promotes local economic growth through a multiplier effect. Halal tourism also fosters ethical business practices and sustainable tourism development aligned with Islamic principles. However, its implementation faces key challenges, including limited infrastructure, complex halal certification procedures, and perceptions of exclusivity among non-Muslim tourists. Therefore, strategic efforts are required to improve Muslim-friendly infrastructure, streamline certification processes, strengthen MSME capacity through training and digitalization, and adopt inclusive branding strategies. These measures are expected to enhance the competitiveness, resilience, and sustainability of halal tourism destinations in the global market.

This study aims to investigate the influence of academic qualifications, managerial capabilities, and Perceived Organizational Support (POS) on emotional exhaustion and its implications for employee productivity at Sunan Kudus Islamic Hospital. Using a quantitative approach, data were collected via a questionnaire from 138 respondents. Instrument evaluation procedures were conducted through validity and reliability tests, while hypothesis testing was analyzed using Structural Equation Modeling (SEM). The findings reveal that academic qualifications and POS have a significant negative effect on emotional exhaustion, indicating that increased intellectual competence and strong organizational support are effective in reducing staff emotional exhaustion. Conversely, managerial capabilities were found to have no significant influence on emotional exhaustion. In the context of performance, the analysis results show that academic qualifications, managerial capabilities, and POS have a partial, positive, and significant effect on work productivity. Practically, this study suggests that hospital management prioritize human capital development and the strengthening of a supportive organizational climate to mitigate emotional exhaustion while accelerating operational efficiency in a sustainable manner.

This study examines the effect of transfer pricing, thin capitalization, and intangible assets on tax avoidance among manufacturing companies listed on the Indonesia Stock Exchange (IDX) during 2022-2024. Using a purposive sampling method, 90 firms were selected, yielding 262 firm-year observations after removing 8 outliers from an initial pool of 270. Tax avoidance is proxied by the Cash Effective Tax Rate (CETR); transfer pricing by the Related Party Transaction ratio (RPT); thin capitalization by the Debt-to-Equity Ratio (DER); and intangible assets by the ratio of intangible assets to total assets. The results indicate that transfer pricing has a significant negative effect on tax avoidance, thin capitalization has a significant negative effect on tax avoidance, and intangible assets do not significantly affect tax avoidance. The model is jointly significant (F = 25.422; p < .001) with an Adjusted R² of 21.92%, indicating that 21.92% of the variation in tax avoidance is explained by the three independent variables. These findings carry important implications for tax authorities seeking to strengthen oversight of related-party transactions and the capital structures of multinational enterprises.

This study aims to analyze the effectiveness of corporate zakat management in reducing economic inequality from the perspective of muamalah. The research employs a library research method with a qualitative-descriptive approach by examining various literature sources, empirical data, and regulations related to corporate zakat in Indonesia. The findings reveal that corporate zakat management achieves optimal effectiveness when zakat funds are distributed through a productive zakat scheme. This scheme is implemented through six main stages: preliminary surveys of beneficiaries, regular assistance, provision of business capital, business partner guidance, motivational training, and periodic evaluations of beneficiaries’ business development. However, practical implementation still faces several challenges. The allocation of funds for business capital among economically disadvantaged communities has only reached approximately 0.4%, while the majority of zakat funds, around 97.1%, are still utilized for consumptive assistance. This condition indicates that the economic empowerment function of zakat has not yet been fully optimized. Therefore, integrative solutions are required, including institutional strengthening through the establishment of Islamic microfinance units such as Baitul Maal wat Tamwil (BMT) internally, as well as stronger government regulations through tax deductible incentive policies externally to support the sustainable optimization of corporate zakat distribution.

The phenomenon of growth in Indonesia’s beauty industry has intensified competition among both global and local skincare brands, including Avoskin. This situation impacts consumer trust Instagram. Avoskin must compete to build brand trust amid the higher exposure and engagement dominance of global brands on social media. Challenges such as the presence of negative reviews and unfavorable consumer perceptions that lead to dissatisfaction represent significant threats to Avoskin’s ability to sustain brand trust. This study aims to determine the influence of electronic word of mouth and brand image of @avoskinbeauty toward brand trust. The research adopts a quantitative approach using the simple random sampling method, involving 400 active Instagram users as respondents. Data were collected through Google Forms and analyzed using IBM SPSS Statistics 30.. The T - test results show that Avoskin’s electronic word of mouth on Instagram has a positive and significant effect on brand trust, with a tcount greater than the ttable value (8.335 > 1.965) and significance < 0.001 < 0.05. Similarly, Avoskin’s brand image also has a positive and significant impact on brand trust, with a tcount greater than the ttable value (22.462 > 1.965) and significance < 0.001 < 0.05. The F - test results indicate that electronic word of mouth and brand image simultaneously have a significant effect on brand trust, with an Fcount greater than the Ftable value (870.240 > 3.02) and significance < 0.001 < 0.05. In conclusion, electronic word of mouth and brand image play essential roles in enhancing brand trust. The implication of this study is that skincare companies should continuously strengthen their digital presence, consistently manage their brand image, and actively facilitate and respond to electronic word of mouth, especially on social media platforms.

Citizen Lawsuit (CLS) is a legal instrument through which citizens file lawsuits against the government for its negligence in fulfilling and protecting public rights. This study aims to analyze juridically the ruling in the CLS case concerning Jokowi’s diploma based on Decision Number 211/Pdt.G/2025/PN Skt. The method employed is normative legal research using both the statute approach and the case approach. Primary legal materials consist of court decisions, while secondary legal materials include relevant literature, journals, and legal doctrines. The findings indicate that the judges’ considerations in this case focused on the plaintiff’s legal standing and the government’s responsibility to fulfill citizens’ rights. The judges appear to have adopted a more progressive perspective in assessing state responsibility, although the implementation of the ruling still faces obstacles due to difficulties in effective enforcement. This study emphasizes the strategic role of CLS as a mechanism for monitoring public policy while also highlighting the urgency of strengthening regulations and ensuring consistency in judicial decisions to provide optimal protection of citizens’ rights.

The development of digital technology has transformed trading patterns through the emergence of live shopping, a phenomenon that enables real-time interaction between sellers and consumers. Although it offers marketing efficiency, this model poses significant legal risks, including misleading information, promotional manipulation, and product non-conformity. This study aims to analyze legal certainty in consumer protection within live shopping transactions, examine the forms of business actors’ liability for consumer losses, and identify obstacles to regulatory implementation along with efforts to strengthen supervision.The research method employed is normative legal research using both a statute approach and a conceptual approach. The results indicate that legal certainty in consumer protection within this ecosystem is grounded in the integration of Law No. 8 of 1999 (Consumer Protection Law) as the lex generalis and Government Regulation No. 80 of 2019 (Electronic Commerce/PMSE) as the lex specialis, which recognizes the validity of real-time electronic contracts. The legal liability of business actors is strict liability in nature, in accordance with Article 19 of the Consumer Protection Law, and may also be construed as a tort (Article 1365 of the Civil Code) in cases involving distortion of visual information.However, the effectiveness of these regulations is hindered by the ephemeral nature of transactions and low levels of digital literacy. This study recommends the implementation of technology-based supervisory systems (suptech), strengthening the oversight function of platforms (PPMSE), and policy synchronization between the Ministry of Trade and the Ministry of Communication and Informatics in standardizing business actor verification to ensure the security of the digital commerce ecosystem.

Family communication plays a crucial role in shaping the character and behavior of adolescents, especially in facing social challenges such as online gambling. This study aims to determine how parental communication patterns influence adolescents' involvement in online gambling activities in Lalang Village, Rana Mese District, East Manggarai Regency. Furthermore, this study also identifies various efforts made by parents to address this problem. The method used was a descriptive qualitative approach, with data collection through interviews, observation, and documentation. The results indicate four family communication patterns implemented by parents: pluralistic, consensual, protective, and laissez-faire. The pluralistic pattern is characterized by open communication and equal discussion, which encourages children to avoid online gambling. The consensual pattern combines warm communication with an emphasis on shared values. Conversely, the protective pattern tends to be dominant, where parents supervise without providing space for dialogue, resulting in children becoming withdrawn. The laissez-faire pattern, with minimal communication, makes children feel free to engage in gambling. This study uses the symbolic interaction theory, namely mind, self, and society. In addition to communication patterns, this study also found that parents undertake various efforts, such as limiting digital device use, providing advice, and increasing supervision of their children's social environment. These efforts demonstrate that their effectiveness is highly dependent on the quality of communication within the family.

This study aims to examine the effect of debt policy and transfer pricing on tax avoidance, with audit quality as a moderating variable. The object of this study is non-banking companies included in the LQ45 index listed on the Indonesia Stock Exchange during 2021-2024, with a total sample of 117 firm-year observations. The data were analyzed using multiple linear regression and subgroup analysis (and chow test), by comparing the regression results between companies audited by Big Four and non-Big Four audit firms. The results indicate that debt policy has a positive and significant effect on tax avoidance, while transfer pricing does not have a significant effect on tax avoidance. Audit quality is proven to moderate the relationship between debt policy and tax avoidance by weakening the effect. However, audit quality does not moderate the relationship between transfer pricing and tax avoidance. These findings suggest that corporate financing decisions through debt remain an important mechanism in tax planning practices, while audit quality plays a crucial role as an external monitoring mechanism in limiting aggressive tax avoidance behavior.

The development of digital technology in the Society 5.0 era presents both challenges and opportunities in history teaching, particularly regarding teachers’ ability to integrate technology and adapt to changes in students’ learning styles. This study aims to analyse the challenges faced by teachers and the strategies employed in digital-based history teaching. The method used is a Systematic Literature Review (SLR) employing the PRISMA approach, involving the stages of identification, screening, eligibility assessment, and inclusion of scientific articles published between 2020 and 2025. From the selection process, 25 relevant articles were identified for qualitative descriptive analysis. The findings indicate that teachers’ digital literacy levels remain at a moderate level and are unevenly distributed, thereby affecting the sub-optimal integration of technology into teaching. Furthermore, changes in students’ learning styles which are increasingly technology-oriented require more interactive and contextual pedagogical innovations. On the other hand, the use of digital media has proven capable of enhancing student motivation and learning outcomes, although this is still hindered by limitations in infrastructure and teachers’ technical competencies. The abundance of historical information on the internet also poses challenges regarding the validity of sources, thus necessitating the strengthening of digital literacy and critical thinking. The implications of this research underscore the importance of the ongoing development of teachers’ digital skills, the improvement of educational facilities, and the implementation of innovative teaching models to ensure that history teaching becomes more relevant and effective, and is capable of fostering critical thinking skills in pupils in the digital age.

Breast tumors are classified into two types, namely benign and malignant tumors, the latter commonly referred to as breast cancer. Breast cancer is one of the major health problems affecting women worldwide, including in Indonesia. According to WHO data in 2022, there were 2.3 million breast cancer cases with 685,000 deaths globally, while in Indonesia, 396,914 cases and 234,511 deaths were reported. The high incidence rate is exacerbated by low public awareness in recognizing early symptoms and performing early detection, resulting in 60–70% of cases being diagnosed at an advanced stage, supported by findings that 65.6% of female students still have a low level of knowledge. Female students were selected as research subjects because they are in a vulnerable reproductive age group and have an important role in increasing awareness of early detection, yet they still have limited knowledge. Based on this, this study aims to design a web-based early detection system for breast tumor risk using the Forward Chaining method, which functions as a tool to identify early symptoms, assess risk levels, and provide information on prevention and initial management. This study employed the method with the Expert System Development Life Cycle (ESDLC) model, consisting of the stages of assessment, knowledge acquisition, design, testing, and documentation, along with the Forward Chaining inference method.

Homemade food is increasingly dominating the choices of consumers who are oriented towards a healthy lifestyle. However, the belief that self-cooking is synonymous with food safety is not always supported by scientific evidence. This Narrative Review aims to build an in-depth thematic synthesis of the various dimensions of food safety risks that arise in the process of preparing healthy homemade food, ranging from biological and chemical contamination, to human behavioral factors as the main agents of contamination. The study was conducted against seven reputable sources of scientific literature published between 2010–2025, including observational, experimental, cross-sectional, and review studies. Four main themes were identified: (1) risky behaviors in the household kitchen as the dominant factor; (2) unexpected cross-contamination pathways including table salt as a vector; (3) chemical and biological contaminants hidden in "healthy" materials; and (4) evidence-based interventions that have been proven to be effective. This review confirms that homemade food safety is a behavioral issue, not just a technical one, so the intervention approach must be multidimensional and sustainable.
