Banda Aceh City has high vulnerability to tsunamis due to its coastal location directly facing the sea and being situated in an active tectonic zone. This study evaluates the spatial distribution of tsunami risk and assesses coastal conditions as disaster mitigation efforts using a mixed-method approach that combines quantitative analysis based on Geographic Information Systems (GIS) and qualitative analysis through field surveys and expert assessments. Three beaches were selected as study locations: Ulee Lheue Beach, Syiah Kuala Beach, and Alue Naga Beach, with risk assessment calculated using the formula Risk = (H × V) / C according to the BNPB framework and overlay techniques in GIS to create risk distribution maps. Coastal condition evaluation focused on coastal vegetation and protective coastal structures assessed using an ordinal scale of 1–5. Results show that Ulee Lheue Beach has the highest mitigation capacity with a score of 64.5% (good category), Syiah Kuala Beach reaches 57.5% (fairly good), while Alue Naga Beach has the lowest score of 28.3% (poor). Correlation analysis yielded a coefficient of r = 0.97, indicating a very strong positive relationship between coastal vegetation and protective coastal structures. Therefore, the study recommends strengthening mitigation strategies through improved protective infrastructure and optimization of coastal vegetation functions, particularly in high-risk areas, to reduce tsunami impacts in the future.

This Study analyzes the fulfillment of dowry requirements as mutamawwal property according to KHI Articles 30-38 and assesses the suitability of crypto assets as dowry under the positive law regime of the Marriage Law, including its implications for the protection of wives’ rights and legal certainty in the digital era. The research employs a qualititative method with a normative juridical approach through literature study of primary sources (the Qur’an, hadith, KHI, Law No. 1 of 1974, Bappebti and OJK regulations, an MUI fatwas) and secondary sources comparising journals, theses, and dissertations on crypto dowry and maqasid syariah, analyzed descriptively-analitycally and comparatively bertween Islamic law and positive law. The findings that demonstrate that normatively, crypto assets can be classified as valuable property within the KHI framework provided they meet the following criteria: possessing economic value, having clear specifications regarding type and amount, being transferable through legal mechanisms (such as gifts or wallet transfers), and being mutually agreed upon by boh parties. Consequently, they are valid as dowry with the value determined at the time of the marriage contract to minimize the impact or price volatility. However, it still poses potential value disputes, necessitating the strengthening of administrative guidelines at the KUA (office of Religious Affairs) and the enhancement of digital forensic capacty in Religious Courts. The study recommends further harmonization among the KHI, crypto asset regulations, and religious fatwas through the development of technical guidelines for crypto dowries oriented toward mashlahah and the protection of wives’ rights in the 4.0 era.

Diarrhea and Tuberculosis (TB) remain significant public health problems in Indonesia, including Rembang Regency. This study aims to analyze the spatial distribution and temporal changes of Diarrhea and TB cases in Rembang Regency during 2023–2024 using a Geographic Information Sistem (GIS) approach. A descriptive-analytic method was applied using secondary data, including administrative boundary shapefiles, disease case data, and health facility data at the sub-district level. Spatial processing and analysis were conducted using QGIS to produce thematic maps and compare disease distribution patterns between years. The results indicate that Diarrhea and TB cases were unevenly distributed across sub-districts and formed distinct spatial patterns. Case changes between 2023 and 2024 varied spatially, reflecting dynamic disease trends. The integration of disease maps with health facility distribution shows that areas with high case numbers were not always supported by adequate health facilities. The implementation of GIS-based maps into a web platform enhances accessibility and supports spatial-based public health decision-making.

This study aims to examine the effect of Corporate Social Responsibility (CSR) costs and financial characteristics on tax avoidance practices among publicly listed companies with the largest market capitalization in Indonesia. The study is motivated by Indonesia’s relatively low tax ratio compared to other emerging economies in the ASEAN region, which suggests the persistence of tax avoidance practices, particularly among large corporations. Grounded in legitimacy theory and agency theory, this research empirically investigates the influence of CSR costs, profitability, leverage, liquidity, activity ratio, growth ratio, and operating cash flow on tax avoidance. The research sample consists of 50 companies with the largest market capitalization listed on the Indonesia Stock Exchange over the 2020–2024 period, employing a census sampling method and unbalanced panel data. Secondary data were obtained from annual financial reports and analyzed using panel data regression techniques. Tax avoidance is measured using the Book-Tax Differences (BTD) approach, while model selection is determined through the Chow test, Hausman test, and Lagrange Multiplier test. The results indicate that, simultaneously, all independent variables have a significant effect on tax avoidance. Partially, the activity ratio has a negative effect on tax avoidance, whereas the growth ratio and operating cash flow have a positive effect on tax avoidance. Meanwhile, CSR costs, profitability, leverage, and liquidity do not show a significant effect. These findings suggest that asset utilization efficiency tends to restrain tax avoidance behavior, while corporate growth dynamics and strong operating cash flows encourage more aggressive tax management strategies. This study provides empirical evidence from an emerging market context and offers insights for tax authorities and regulators in designing more effective, risk-based tax supervision policies.

This study discusses the legal problems faced by tobacco farmers in Sukorejo Village, Kotaanyar District, Probolinggo Regency due to the closure of large tobacco warehouses that force them to depend on middlemen. This condition causes legal uncertainty, an imbalance in the bargaining position, and alleged violations of the principle of healthy business competition, thus having a direct impact on the economic sustainability of farmers. The focus of this research is to describe the practice of business competition and its impact on tobacco farmers and explain the form of legal protection from the perspective of business competition law and sharia economic law. The research method used is empirical law with a sociology approach to law and legislation, through observations, interviews, and documentation from farmers, middlemen, and factories. The results of the study show that there is dominance of middlemen in cooperation with large factories so that farmers lose freedom in determining prices. This condition does not reflect the principles of fairness and transparency in business competition. Legal protection is still weak because there is no regulation of the basic price or a definite buying and selling mechanism. In the perspective of sharia economic law, the practice violates the principles of al-adl (justice) and al-amanah (honesty). In conclusion, preventive legal protection is needed in the form of price regulation and the establishment of marketing cooperatives, as well as repressive protection through law enforcement against unfair business competition practices.

This study aims to analyze the effect of transformational leadership (X1), work experience (X2), and social support (X3) on employee performance (Y) at PT Putra Sentosa Mandiri. This research also seeks to determine the partial effects of each independent variable as well as their simultaneous effect on employee performance. The research method used is a quantitative approach with primary and secondary data sources. The sampling technique applied was saturated sampling, in which the entire population was used as the sample, consisting of 34 employees of PT Putra Sentosa Mandiri. Data were collected through questionnaires, interviews, literature studies, and documentation. The data analysis techniques included validity tests, reliability tests, normality tests, linearity tests, heteroscedasticity tests, multicollinearity tests, multiple linear regression analysis, t-tests, F-tests, and the coefficient of determination (R²). The results indicate that transformational leadership has a positive but not significant effect on employee performance, work experience has no positive and insignificant effect on employee performance, while social support has a positive and significant effect on employee performance. Simultaneously, transformational leadership, work experience, and social support do not have a significant effect on employee performance at PT Putra Sentosa Mandiri.

Financial literacy and lifestyle are two important factors influencing students' ability to manage their personal finances. Students are in a transitional phase toward financial independence and are therefore required to make rational financial decisions amidst the influence of modern lifestyles. This study aims to understand how students interpret financial literacy and lifestyle in their daily financial management practices. This study used a qualitative approach with descriptive methods. Data were collected through in-depth interviews and observations of active students from various backgrounds. The results indicate that students generally understand the basic concepts of financial literacy, such as managing pocket money and preparing a simple budget. However, the application of this financial literacy is often suboptimal due to the influence of a consumptive lifestyle and social pressures. This study provides important implications for the development of contextual financial literacy education programs in higher education environments. The implication of this research is the importance of developing financial literacy education programs that are more contextual and relevant to students' lifestyles so they can manage their personal finances more wisely and effectively.

This study aims to conduct a Systematic Literature Review (SLR) regarding the influence of career development on organizational commitment. Based on the analysis of various scientific articles, career development is an important approach in human resource management, which focuses on improving employees’ skills, enthusiasm, and readiness to face job challenges and promotion opportunities. On the other hand, organizational commitment refers to the emotional connection that employees have with their workplace, which includes aspects of emotional attachment, obligation, and enduring bonds. The results of the systematic literature review indicate that many previous studies have found a strong and positive correlation between career development and organizational commitment. Workers who are aware of support for their career development, including training programs, mentoring, or predetermined career paths, generally show a higher level of dedication to their organization. Furthermore, various studies have shown that career development can also have an indirect effect on organizational commitment through mediating factors such as job satisfaction, work motivation, and employee performance. However, several studies have shown that career development does not always have a significant impact on organizational commitment, particularly in organizations without a structured career system or when employees have negative perceptions of career opportunities. These varying results highlight the existence of contextual factors that influence the relationship between variables. Overall, this study offers in-depth insights into the significance of career development as a strategic factor in enhancing organizational commitment, along with suggestions for organizations and future researchers conducting similar studies.

This research aims to analyze in depth the level of understanding among Islamic Religious Education (PAI) students at the Islamic Institute of Nahdlatul Ulama (IAINU) Tuban regarding the concept of Ihsan and its implementation in community life. The urgency of this study is based on the strategic role of PAI students as future educators who are required to integrate spiritual dimensions and social ethics into their personalities. This research employs a quantitative approach with a descriptive survey method. Data were collected through a Likert scale questionnaire instrument that had been tested for validity and reliability, distributed to a sample of students selected through proportional random sampling. Data analysis was carried out systematically using descriptive statistics to calculate the mean value and categorization percentage across cognitive, affective, and applicative dimensions. The results indicated that the overall level of understanding of Ihsan among PAI students at IAINU Tuban falls into the low category, with a total mean score of 1.909. In detail, the affective dimension recorded the lowest score, indicating a weakness in the internalisation of spiritual consciousness, while the applicative dimension showed a slightly higher score but remained within the low category. It is concluded that there is a significant gap between the idealism of the Ihsan concept and the actual understanding of students in the field. These findings provide important implications for the need to reconstruct character-building strategies and the PAI curriculum, emphasizing the aspect of inner spiritual internalisation over mere formalistic cognitive knowledge transfer to produce graduates with authentic social piety.

This study aims to determine the effectiveness of the use of the artificial intelligence-based application (AI-Based Application) Duolingo in improving vocabulary mastery of EFL (English as a Foreign Language) students in Indonesia. This study used a descriptive quantitative approach with a single-group pre-test and post-test design involving 20 students of class VII C of SMP Negeri 1 Mappakasunggu. Data were collected through vocabulary tests, questionnaires, and classroom observations. The results showed a significant increase in students' vocabulary mastery, marked by an increase in the average score from 61 (fair category) in the pre-test to 78 (good category) in the post-test. Most students gave a positive perception of the use of Duolingo, especially regarding the gamification features, instant feedback, and simple and attractive display, which can increase motivation and learning engagement. The results of the observation also showed that students were more active and enthusiastic in using this application compared to traditional learning methods.

Listening skills are fundamental in English language learning because they are the main gateway to language proficiency. However, students often face obstacles such as differences in accents, the speed of native speakers, and limited vocabulary. This study aims to describe the use of the Spotify application as a learning medium to improve students' listening skills. This study uses a descriptive qualitative approach. The research subjects were third-semester students of the English Education Study Program at UIN Sumatera Utara (UINSU) in class TBI 2. Data were collected through questionnaires covering content usage patterns, duration, and application feature utilization. The results showed that: Students actively use Spotify (music and podcasts) as a source of authentic language input independently. Using Spotify has a positive impact on vocabulary comprehension, pronunciation, intonation, and conversation comprehension skills. The playback speed feature helps students control the audio speed according to their ability level, making the learning process more flexible and personalized. Consistent listening duration (15–30 minutes) is effective in supporting the development of listening skills without causing cognitive fatigue.

This study analyzes Tretan Muslim's Mutant series as a digital cultural text containing social criticism through the approach of Karl Marx's literary sociology. Amidst the limited academic studies on digital humor as a medium of social representation, this study investigates how class relations, social conformity, and symbolic domination are represented through the humorous interactions of the characters. Using qualitative methods with content analysis, data were obtained from in-depth observations of several key scenes and supported by literature on Marxism, social criticism, and digital culture. The results show that humor in Mutant works through three main layers: (1) class representation, (2) critique of conformity culture, and (3) commodification of identity. Thus, this study confirms that Mutant functions not only as entertainment, but also as a medium of social criticism that reveals the mechanisms of domination and resistance in contemporary society. These findings contribute to the expansion of the study of literary sociology in the context of digital culture and open up new reading spaces for humor as a means of social reflection.

This study examines deep learning as an educational approach within the Indonesian education system by exploring its conceptual foundations, policy frameworks, and practical implementation. The background of the study arises from ongoing challenges in Indonesian classrooms, where teacher-centered instruction and surface learning practices remain dominant, limiting students’ critical thinking, engagement, and real-world application of knowledge. The study aims to analyze how deep learning, characterized by mindful, meaningful, and joyful learning, is conceptualized in educational theory, reflected in national education policies, and implemented in classroom practices. Using a qualitative literature review method, data were collected from peer-reviewed national and international journal articles, academic books, and research reports related to deep learning in education. The data were analyzed through thematic synthesis to identify patterns concerning implementation strategies, learning outcomes, and implementation challenges. The findings indicate that deep learning contributes positively to students’ cognitive development, motivation, engagement, and 21st-century skills, particularly critical thinking, collaboration, and creativity. However, its implementation in Indonesia faces several obstacles, including limited teacher competence, inadequate assessment systems, insufficient contextual learning materials, and unequal technological infrastructure. The study concludes that successful deep learning implementation requires integrated policy support, continuous teacher professional development, contextualized curriculum design, and equitable access to learning resources. These findings provide practical implications for educators, curriculum developers, and policymakers in strengthening sustainable and humanistic education in Indonesia.

The phenomenon of unregistered marriages in Indonesia is a complex issue that continues to spark debate between religious legitimacy and legal validity under national law. From an Islamic legal perspective, marriage is considered valid if it meets the essential pillars and requirements, such as the presence of a guardian, two witnesses, a dowry, and the consent (ijab qabul) both the bride and groom. However, according Indonesian national law, specifically Law Number 1 of 1974 concerning Marriage and the Compilation of Islamic Law (KHI), every marriage must be officially registered to receive legal recognition and protection. This discrepancy between the two legal systems raises serious problems, particularly regarding the legal status of wives and children, inheritance rights, and legal protection for women in both the private and public spheres. This study aims analyze the issue of unregistered marriages in Indonesia from the perspectives of Islamic law and national law, and to identify the social and legal impacts unregistered marriages. The approach used is normative-juridical, by analyzing legislation, classical and contemporary Islamic legal literature, and empirical case studies in the community. Research findings indicate that although unregistered marriages are considered valid religiously, they lack legal force the eyes of the state, leading to unequal rights for women and children. This situation results in difficulties obtaining birth certificates, inheritance rights, and legal protection cases divorce or domestic violence. This research emphasizes the need for synchronization between Islamic and national legal systems through strengthening regulations and public education regarding the importance of marriage registration.

This study aims to analyze the effectiveness of enforcement actions undertaken by the Business Competition Supervisory Commission (KPPU) in Indonesia in 2025 against various forms of unfair business practices. Using a juridical-normative approach combined with an analysis of recent market data, this article examines the KPPU’s strategic response to the challenges posed by the digital economy. The study focuses on the enforcement of competition law against cartel practices, algorithmic collusion, abuse of dominant positions, and anticompetitive vertical integration, particularly in the logistics and food sectors. The findings indicate that 2025 marks a significant turning point in Indonesian competition law enforcement, characterized by a shift toward more aggressive and data-driven supervision. Strengthening enforcement authority, particularly in the execution of fines, along with the adoption of algorithmic audits, has enhanced the KPPU’s ability to detect and deter anticompetitive behavior. These measures aim not only to preserve market efficiency and fair competition but also to ensure that national economic growth is not concentrated among a small number of dominant firms, thereby promoting more equitable opportunities for micro, small, and medium enterprises (MSMEs).

This study aims to conduct an in-depth analysis of the psychological journey of the character Rangga Raja in the novel 0 MDPL by Nurwina Sari. The main focus of the study is to identify the inner conflicts experienced by the protagonist as well as the dynamics of the personality structure consisting of the Id, Ego, and Superego that shape his psychological development throughout the storyline. This research employs a literary psychology approach using a qualitative descriptive method, conducted through a literature review and document analysis of the novel text as the primary data source. The findings indicate that Rangga Raja experiences complex emotional conflicts resulting from past trauma, experiences of loss, and failures in romantic relationships. These conditions are reflected through the tensions and interactions between the Id, Ego, and Superego within himself. The process toward the “zero point” (0 MDPL) is interpreted as a symbol of an identity crisis phase as well as a stage of self-reconstruction, in which the protagonist undergoes processes of reflection, self-acceptance, and openness to change. In addition, Rangga’s interactions with other characters, such as Andini, La Nina, and Nadia G. Sahara, play an important role in his psychological recovery and healing process. This study confirms that the novel 0 MDPL represents a profound reflection on human psychological dynamics, the search for identity, and the gradual process of inner healing.

Multatuli Area 4 is highly susceptible to flooding due to its close location to the Deli River and inadequate environmental management, which exacerbate the risk during the rainy season. Despite this vulnerability, community preparedness remains limited, leaving residents exposed to potential damage and loss. This study employed a descriptive qualitative approach, collecting data through in-depth interviews and direct observations with purposively selected informants who have knowledge of local flooding experiences. The findings reveal that while residents are generally able to recognize early signs of flooding, their responses are largely reactive rather than proactive. Several factors contribute to this low level of preparedness, including limited perception of risk, insufficient economic capacity to implement preventive measures, declining social cohesion and cooperation, and underutilization of available mitigation facilities and infrastructure. These conditions highlight the need for improved community awareness, better access to resources, and strengthened disaster management strategies to enhance flood preparedness in Multatuli Area 4.
