The implications of these findings suggest that destination managers and local government authorities should consistently enforce cleanliness policies, strengthen integrated waste management systems, and provide adequate sanitation facilities to enhance the attractiveness of Lembah Harau and support sustainable tourism development, without neglecting the need for continuous monitoring, evaluation, and improvement in these areas.

This study aims to analyze the factors that influence students' interest in continuing their education to college using a machine learning approach. Data was collected through an online questionnaire completed by 727 students between July 27 and August 22, 2025, covering 23 variables consisting of respondent identity (gender, grade level, major) as well as internal and external factors such as parental support, learning motivation, and preferred type of college. The data preparation stage was carried out through column cleaning, deletion of empty data, encoding of categorical variables, and division of the dataset into 80% training data and 20% test data. The Naive Bayes algorithm of the CategoricalNB type was used because it was suitable for the categorical nature of the data. The evaluation results showed that the model was able to predict student interest with 96% accuracy. For the class of students interested in continuing their studies, the precision, recall, and F1-score values were above 0.95, while the performance in the class of students who were not interested was slightly lower due to the smaller amount of data. These findings show that Naive Bayes is proven to be effective and reliable in classifying students' interest in continuing their studies and can be the basis for decision-making in designing more targeted educational strategies.

This study elaborates on the concept of humanism in Islamic educational philosophy by highlighting in greater depth the role of humans as caliphs on earth. Humanism from an Islamic perspective not only focuses on humans as rational beings but also emphasizes the moral, spiritual, and social responsibilities inherent in the mandate of the caliphate. This study applies a qualitative approach with a literature study, where data is obtained from various written sources such as scientific articles and academic publications that discuss humanism in Islamic education and the concept of the human caliphate. The data collection process is carried out through searching, selecting, and organizing literature relevant to the focus of the study. The collected data are then analyzed using descriptive-qualitative techniques through the stages of simplifying information, grouping findings, and formulating systematic conclusions. The results of the study indicate that the position of humans as caliphs requires the development of intellectual, ethical, and spiritual potential in an integrated manner in the educational process. Therefore, Islamic education needs to be directed towards a holistic humanization process, which not only strengthens reasoning and social character but also fosters a transcendental awareness of human relationships with God, fellow humans, and nature. Thus, humanism in Islamic education is not secular, liberal, or anthropocentric, but is firmly rooted in divine values ​​that harmoniously unite the divine and human dimensions.

This study aims to explore public perceptions of urban spatial planning policies in addressing the impacts of urbanization in Medan. Data were collected using a 15-item Likert-scale questionnaire and analyzed descriptively, using proxy factor analysis (PCA), and using cross-demographic difference tests. The initial sample size consisted of seven respondents. The results showed strong recognition of the impacts of urbanization, such as increasing land pressure, slums, and limited infrastructure. The majority of respondents also supported data-driven spatial planning to address these issues. However, there were doubts about the effectiveness of government land conversion controls, which were considered suboptimal. Nevertheless, these results demonstrate the importance of public participation in urban planning. The internal reliability of this study was relatively low, with a Cronbach's alpha value of -0.112, making the findings exploratory in nature. The researchers recommend that this study be conducted with a larger sample size and further testing to obtain more representative and valid results, as well as to delve deeper into public perceptions of urban spatial planning policies.

This study examines how children and their relationship with nature are represented through the character of Antonio in the film Encanto (2021). Antonio is portrayed as a child who can communicate with animals, reflecting innocence, empathy, and a spiritual closeness to nature. This study aims to describe how children's relationship with nature is depicted in the film and to interpret the symbolic meaning behind these interactions. The method used in this study is a descriptive, qualitative approach that draws on theories of child development, symbolism, and children's imagination. The results of this study show that among children, Antonio reflects a harmonious, loving, and open attitude towards other life forms. Animals in the film serve as moral and emotional symbols that reflect the nature of children: the jaguar symbolizes courage, the toucan symbolizes honesty and cheerfulness. In contrast, the capybara symbolizes peace of mind. This study shows that children's films can be a tool for building ecological awareness and social empathy through imagination. The implications of this study underscore the importance of strengthening empathy and environmental balance in children's education through literature and film.

This study aims to analyze the issue of online gambling in Indonesia and examine the urgency of extradition agreements as a legal instrument to prosecute online gambling operators who conduct their activities from abroad. Although gambling has been declared a criminal act under the Indonesian Criminal Code (KUHP) and the Electronic Information and Transactions Law (ITE Law), its enforcement has not been effective due to the transnational nature of this crime, in which gambling operators run their platforms from other countries, placing them beyond the direct reach of Indonesian jurisdiction. The research employs a normative legal methodology, examining statutory regulations, principles of criminal law, and relevant legal literature. The objects of study include the 1945 Constitution, the Criminal Code, and the ITE Law as the legal foundations for combating online gambling, as well as provisions concerning extradition within the framework of international cooperation. The findings indicate that although Indonesia normatively possesses legal grounds to prosecute perpetrators abroad through the principles of personality and protection, implementation remains hindered by state sovereignty and jurisdictional limits. Government efforts to block gambling websites have proven ineffective, as new sites continually emerge. Therefore, extradition agreements are essential and urgent as a solution to overcome jurisdictional barriers, enabling the transfer of offenders to Indonesia for prosecution and ensuring state protection for citizens from the harmful impacts of online gambling.

Traditional food is a national asset. It not only serves as a source of energy for the community, but also serves as a form of food security, an economic driver, a source of healthy food, and a culture steeped in noble values. The widespread consumption of unhealthy foods by students, especially elementary school students, is one of the reasons for this outreach activity. The health issues surrounding junk food must be addressed by offering healthy alternatives, such as traditional foods. Traditional food is not only related to food, but can also be linked to ethnomathematics, where culture in the form of food is studied from a mathematical perspective. Elementary school students not only consume traditional foods but also interpret these foods in mathematical contexts, such as geometry and numbers. In this way, students will be able to visualize mathematical elements not only when reading math textbooks but also when consuming traditional foods that are part of their daily environment. Despite their traditional nature, students actually enjoy some traditional foods. This is a frequent conflict between the current generation and traditional culture. They better understand how to prepare traditional foods, appreciate the richness of local culture, and develop a love for their culture and homeland.

The development of educational tourism villages is one of the sustainable tourism strategies that integrates learning activities, environmental conservation, and local community empowerment. This study aims to analyze the potential and development strategies of Belawa Village as an educational tourism village in Cirebon Regency. The research employed a qualitative method with a case study approach. Data were collected through field observations, in-depth interviews with managers and community members, and literature review. The results indicate that Belawa Village has strong tourism potential, particularly in educational tourism based on the conservation of the Belawa softshell turtle (Amyda cartilaginea), nature-based tourism, and local cultural tourism. Educational activities such as outing classes, animal introduction programs, environmental education, and cultural arts training have been implemented and fulfill the elements of something to see and something to do in educational tourism. However, the development of this educational tourism village has not yet been optimal due to limitations in destination management, supporting facilities and infrastructure, promotion, and human resource capacity. Therefore, integrated development is required through the packaging of educational tourism attractions, improvement of human resource competencies, provision of supporting facilities, and collaboration among the government, community, academics, and tourism stakeholders. The development of Belawa Village as an educational tourism village has the potential to provide economic, social, and educational benefits while supporting environmental conservation and strengthening local cultural identity.

The danger of cadmium contamination in water sources remains a crucial environmental issue due to its persistent nature and high toxicity level, which poses serious risks to human health and ecosystems. Cadmium is a non-biodegradable heavy metal that can accumulate in living organisms over time. The presence of these toxic Cd²⁺ ions is known to trigger damage to vital organs such as the liver and kidneys; therefore, reducing their concentration in aquatic environments is of paramount importance for environmental protection and public health safety. Among various treatment methods, adsorption is considered one of the most effective and economical techniques for removing heavy metal ions from contaminated water. In this study, the capability of mesoporous silica MCM-48-NH₂ as an adsorbent for Cd²⁺ ions was systematically evaluated. The adsorption performance was examined by investigating several important parameters, including contact time, solution acidity level (pH), and initial Cd²⁺ concentration. Furthermore, the adsorption mechanism and interaction between Cd²⁺ ions and the adsorbent surface were analyzed using Langmuir and Freundlich isotherm models. The results demonstrate that the adsorption process of Cd²⁺ ions onto MCM-48-NH₂ tends to follow the Langmuir isotherm model, indicating monolayer adsorption behavior, with a maximum adsorption capacity of 0.66 mmol g⁻¹.

This study examines the comparative volatility of gold and Bitcoin over the period January 2020 to August 2025, using monthly data and employing descriptive statistics, the Augmented Dickey-Fuller (ADF) test, GARCH (1,1), and the Dynamic Conditional Correlation Generalized Autoregressive Conditional Heteroskedasticity (DCC-GARCH) model estimated with EViews 13. The results show that Bitcoin is characterized by extreme and persistent volatility, reflecting its speculative nature, whereas gold remains stable and functions as a conventional safe-haven asset. Correlation analysis indicates that the relationship between gold and Bitcoin is generally weak but dynamic, as the strength and direction of their co-movements change across different market conditions. These findings highlight the potential role of gold as a hedge and Bitcoin as a speculative diversifier, offering insights for portfolio diversification and risk management. These results also suggest that investors should carefully consider their risk tolerance and investment horizon when allocating assets between traditional and digital commodities.

The increasing volume of online hotel reviews provides valuable insights into customer perceptions but poses challenges for manual analysis due to its unstructured nature. This study aims to compare the performance of Recurrent Neural Network (RNN) and Bidirectional Encoder Representations from Transformers (BERT) in hotel review sentiment analysis.

Hypertension is a major public health problem with an increasing prevalence and is often undetected due to its asymptomatic nature, leading to serious complications if not properly controlled. Low levels of public knowledge and poor adherence to preventive behaviors, routine health checks, and treatment remain significant challenges in hypertension management at the community level. This community service program aimed to improve public knowledge and awareness of hypertension through the implementation of the CERDIK and PATUH approaches. The program employed a community-based promotive and preventive method, including health education, blood pressure screening, and interactive discussion and counseling. The activity was conducted in RW 013, Kapuk Subdistrict, Cengkareng District, involving 60 adult and elderly participants. Knowledge levels were assessed using pre-test and post-test questionnaires and analyzed descriptively. The results demonstrated a substantial improvement in participants’ knowledge after the health education intervention, with the mean knowledge score increasing from 35 before the intervention to 80 after the intervention. In addition, the variation in knowledge levels among participants became more homogeneous following the educational activities. High community enthusiasm and active participation during the program reflected positive acceptance and engagement with the hypertension education initiative. This community service activity confirms that community-based health education using the CERDIK and PATUH approaches is effective as a promotive and preventive strategy to enhance public knowledge of hypertension. Improved knowledge is expected to encourage healthier lifestyle behaviors and greater adherence to hypertension control practices, thereby supporting sustainable and independent blood pressure management within the community.

Injustice against women in contemporary Islamic law practice is still a serious problem, especially in cases of divorce, child custody, and the division of common property, which are often decided textually without considering the social, economic, and psychological aspects of women. This phenomenon shows that the application of Islamic law is still normative and does not fully reflect substantive justice as the purpose of maqāṣid al-syarī'ah. This research aims to analyze the nature of justice for women in the modern era, identify the steps needed to realize this justice, and formulate Islamic legal solutions based on maqāṣid al-syarī'ah that can be applied contextually in the religious justice system. The research method used is qualitative with a normative-empirical approach through literature analysis, case studies, and empirical data from religious court decisions and reports of official institutions such as Komnas Perempuan. The results of the study show that justice for women can only be achieved through a dynamic maqāṣid approach, by placing the interests of women and children above the legal-formalities of classical fiqh. The efforts needed include the integration of empirical data in judges' decisions, reform of religious justice policies, increasing the capacity of judges in understanding maqāṣid, and empowering women through legal literacy.
