Teacher professionalism is a key factor in improving the quality of education, especially in the context of rapid changes that demand continuous competency development. Therefore, sustainable professional development for teachers has become an essential need. This article aims to examine strategies for developing teacher professionalism through reflection and the implementation of best practices in learning. The method used is a literature study with a descriptive qualitative approach, by analyzing various sources such as scientific journals, books, and relevant articles. The results show that reflection plays an important role as a means of self-evaluation that helps teachers continuously improve the quality of learning, while best practices provide concrete examples of effective and innovative teaching practices. Reflection enables teachers to identify strengths and weaknesses in their instructional processes, thereby encouraging continuous improvement and adaptive teaching strategies. Meanwhile, best practices serve as a reference for implementing evidence-based and student-centered learning approaches that can enhance classroom engagement and learning outcomes. The integration of reflection and best practices is proven to strengthen teachers' competencies holistically by combining critical self-assessment with proven pedagogical strategies. This synergy also supports collaborative learning among educators and encourages the sharing of effective teaching experiences. Thus, sustainable teacher professional development can be achieved through the consistent application of these strategies, ultimately contributing to improved educational quality and more effective learning environments in schools.

This research is motivated by the urgency of integrating humanistic values into literature learning for character building among students, as well as the lack of scientific studies that thoroughly examine the novel ‘3726 MDPL’ by Nurwina Sari. The purpose of this research is to identify and analyze the humanistic values contained in the novel and to describe its relevance as teaching material in high schools. The study employs a qualitative descriptive method with a case study design, where data is collected thru content analysis and documentation techniques, and then analyzed using the interactive model of Miles, Huberman, and Saldana. The research results show that there are six forms of humanistic values in the novel, namely respecting others opinions, cooperation, caring for others, helping each other, solidarity, and self-sacrifice. These values have significant pedagogical relevance as teaching materials in high school literature because the align the Indonesian Language Learning Outcomes Phase F and the Pancasila Student Profile, particularly in the dimensions of mutual cooperation and global diversity, thus making them an effective medium for fostering empathy and social sensitivity among students.

The moral crisis faced by the Indonesian nation is a serious challenge that can threaten the integrity and sustainability of the country's future. Phenomena such as corruption, intolerance, and weakening social integrity are clear evidence of the declining implementation of the noble values ​​contained in Pancasila. Pancasila Education has a strategic position in building national character and instilling moral values, especially in the younger generation. This article aims to examine the moral crisis in Indonesia and analyze the role of Pancasila Education in providing solutions to these problems. This study uses a literature research method to assess the relevance of Pancasila values ​​and the effectiveness of the implementation of Pancasila Education. The study results show that Pancasila values ​​such as religiosity, humanity, unity, democracy, and social justice have great potential in forming moral individuals. However, there are various challenges, including low student interest, lack of innovation in teaching, and the influence of globalization that can hinder the optimization of Pancasila Education. To overcome these obstacles, strategic steps are needed such as strengthening the curriculum, improving the quality of educators, and collaboration between families, schools, and the community. With maximum implementation, Pancasila Education can be the main key to rebuilding the nation's morality.

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.

. Malnutrition rates among children remain quite high, according to 2024 national statistics, which indicate that good eating habits in accordance with balanced nutritional needs are not yet ideal. Children's eating habits, dietary diversity, and parental understanding all impact their nutritional status. To promote optimal growth and development in children, it is crucial to monitor and establish appropriate eating habits from an early age. The aim of this study was to determine the relationship between eating habits and nutritional status of preschool-aged children. This study used a cross-sectional analytical design and quantitative methodology. Purposeful sampling was used to select a sample of 33 children from the 50 children in the study population. The study was conducted between September 22 and October 1, 2025. A Food Frequency Questionnaire (FFQ) was used to examine dietary patterns, while nutritional status was measured through weighing using a digital scale. Based on the findings, 22 children (66.7%) had a healthy diet, while 11 children (33.3%) had a poor diet. The Chi-Square statistical test showed a p value of 0.008 (p < 0.05), indicating a relationship between eating habits and nutritional status in preschool children at Taman Annisa Miruek Kindergarten, Aceh Besar Regency. According to balanced nutrition guidelines, parents should regularly assess their children's growth and focus more on the diversity and balance of their food intake. To improve children's nutritional status as much as possible, schools are required to collaborate with health workers to educate parents and children about nutrition.

This research is motivated by the reality of ethnic and cultural diversity in congregation life which reflects the dynamics of a multicultural society, where differences in cultural identity have the potential to cause social friction if not managed wisely. This research uses a descriptive qualitative approach with normative studies, with data collection techniques through interviews, observations, and documentation of informants consisting of pastors, congregation councils, and presbyters. The theory used is Ralph Linton's role theory which explains how individuals carry out social functions according to their status in society. The results of the study indicate that the life of the GMIT Sion Oepura congregation is characterized by multicultural dynamics as seen from the diversity of ethnicities such as Timor, Rote, Sabu, Flores, and Alor which not only enriches church life through cultural expressions in worship and church activities, but also gives rise to symbolic friction between ethnic groups, such as the tendency for the dominance of certain cultural symbols and the emergence of group ego attitudes in several worship activities, for example in the celebration of Language and Culture Month. In this situation, religious leaders play a role as leaders who embrace diversity, mediators in managing potential conflicts, and social and moral role models for the congregation through sermons, pastoral guidance, and various service activities that involve the entire congregation without differentiating cultural backgrounds. Despite the existence of cultural differences and the tendency for certain symbolic dominance, religious leaders are able to manage this diversity normatively so that it does not develop into open conflict. This study concludes that the role of religious leaders is very important in strengthening social solidarity and maintaining harmony in multicultural congregations.

This study examines the determinants of the Jakarta Composite Index (JCI) based on three main macroeconomic factors namely inflation, the USD/IDR exchange rate, and the SBI interest rate (BI Rate) covering the period January 2020 to December 2025, in the context of post-COVID-19 pandemic recovery and global economic turmoil. A quantitative approach was employed using the Ordinary Least Squares (OLS) method, with 72 monthly observations derived from secondary data sourced from official institutions including Bank Indonesia (BI), the Central Statistics Agency (BPS), the Indonesia Stock Exchange (IDX), and the Financial Services Authority (OJK). Classical assumption tests were applied comprising the Jarque-Bera normality test, Variance Inflation Factor (VIF) for multicollinearity, Breusch-Godfrey for autocorrelation, White Test for heteroscedasticity, and Ramsey RESET for model specification. Partially, inflation, exchange rate, and BI Rate each demonstrate a positive and significant effect on the JCI (p < 0.05). Simultaneously, all three variables exert a significant combined influence on the JCI, with a coefficient of determination R² = 0.4414, indicating that the model explains 44.14% of the variation in the JCI. The remaining 55.86% is attributed to other variables outside the model. Classical assumption test results reveal violations of normality, autocorrelation, and heteroscedasticity assumptions, although the model is free from multicollinearity. These findings confirm that Bank Indonesia's monetary policy has a significant and measurable impact on capital market performance. Further research is recommended using more advanced time series models such as GARCH or VECM to address violations of classical assumptions and improve estimation efficiency.

This study describes the fluctuating exports and imports over the past five years, from 2020 to 2024, which also influenced fluctuations in Indonesia's foreign exchange reserves. The purpose of this study is to determine the effect of exports and imports on Indonesia's foreign exchange reserves from 2020 to 2024. The research method is quantitative using secondary data obtained from the Indonesian Central Bureau of Statistics. The population in this study was 5 years from 2020 to 2024. Data analysis used classical assumption tests consisting of normality tests, multicollinearity tests, and heteroscedasticity tests. In addition, hypothesis tests were also used, consisting of partial tests, simultaneous tests, and coefficient of determination tests. The results of this study indicate that the export variable has a negative effect on Indonesia's foreign exchange reserves from 2020 to 2024. The import variable has a positive effect on Indonesia's foreign exchange reserves from 2020 to 2024. Export and import variables do not simultaneously affect Indonesia's foreign exchange reserves from 2020 to 2024. The implication of this research is that the government needs to manage export and import policies more effectively, as they do not always have the theoretical impact on foreign exchange reserves. Improvements in export quality and import controls are needed, as well as consideration of other factors such as foreign investment and economic policies to maintain the stability of foreign exchange reserves.

This study aims to analyze the influence of the TikTok application on changes in the lifestyles of teenage girls in the digital age. TikTok, as one of the most popular social media platforms among the younger generation, plays an important role in shaping the way they think, behave, and interact socially. This study uses a qualitative descriptive approach to describe the challenges faced in maintaining a positive lifestyle, as well as efforts to minimize its negative impacts. The results of the study show that TikTok has a dual impact: positively, this platform facilitates self-expression, creativity, and the development of interests; however, negatively, excessive use can trigger consumptive behavior, decreased self-confidence, and deviations from social and cultural values. Factors such as beauty trends, imitation of foreign cultures, and social pressure in the virtual world also influence the lifestyles of adolescent girls. To reduce these negative impacts, it is necessary to improve digital literacy, parental supervision, and education on social media ethics in schools. With a wise approach, TikTok can be used as a positive tool in building the character, creativity, and self-confidence of adolescent girls in the digital age.

The study underscores the need forfurther empirical research to examine the effectiveness of mindful leadership across diverse educational contexts.

This study aims to analyze the impact of bullying on adolescents’ mental health through a literature review. The method used is a literature review, which involves the collection and analysis of various relevant scientific articles published in the last five years.  Data were obtained from journals and related scientific works, then systematically analyzed to identify patterns of association between bullying and adolescents’ mental health. The results of the review indicate that the majority of studies reveal a negative impact of bullying on mental health, such as the emergence of anxiety, depression, stress, low self-esteem, and difficulties in social interaction. However, some studies found that this relationship was not statistically significant, suggesting the role of other factors, such as social support, family circumstances, and an individual’s ability to cope with stress. In addition to affecting victims, bullying also impacts perpetrators and bystanders, making it a complex phenomenon. Therefore, comprehensive prevention and intervention efforts are needed through collaboration between schools, families, and the community.

This article explores the map of Christian education approaches from theological, pedagogical, psychological, and contextual perspectives. Christian education plays a vital role in shaping the faith, character, and spirituality of students in a comprehensive manner. Using a literature review method, the study analyzes various sources on Christian education theology. The findings reveal that the theological approach emphasizes the Bible as the primary foundation for learning, while the pedagogical approach focuses on active and participatory teaching methods. The psychological approach tailors instruction to the developmental stages of students, and the contextual approach links faith with students' real-life experiences. Each approach has its strengths and limitations, and Christian educators are encouraged to integrate these approaches to achieve holistic learning goals. The study emphasizes the importance of collaboration among schools, families, and churches to create an educational ecosystem that fosters the spiritual and character growth of students. By combining these approaches, educators can better equip students for both spiritual and personal development.

The implementation of smoking prohibition policies in Islamic boarding schools continues to depend largely on manual monitoring methods, which often face challenges related to consistency and supervision range. This study aims to design an Internet of Things (IoT)-based cigarette smoke detection system as an alternative monitoring approach that is more effective, measurable, and sustainable. The system design combines an MQ-2 gas sensor with a NodeMCU ESP8266 microcontroller programmed through the Arduino IDE platform. When smoke levels detected by the sensor exceed the predetermined limit, the system automatically triggers a buzzer and LED as warning indicators while simultaneously sending monitoring data to cloud-based platforms such as Firebase or ThingSpeak for real-time observation through web interfaces. The research outputs include a comprehensive system design consisting of system architecture, electronic circuit schematics, flowcharts, and pseudocode that are systematically arranged to support future prototype development and implementation. Through this design, the proposed system is expected to provide an initial technological solution that can enhance the effectiveness of monitoring and enforcing smoke-free regulations within Islamic boarding school environments.

Anemia is a common nutritional problem among adolescent girls and can affect health, learning ability, and the quality of future generations. Hemoglobin (Hb) levels can be influenced by dietary intake, such as folic acid and vitamin C, as well as consumption behaviors, including tea drinking habits and adherence to iron supplementation (TTD). This study aimed to examine the relationship between folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption with hemoglobin levels among adolescent girls in senior high schools in Tuban District. This study used a cross-sectional design with a sample of 325 respondents selected through probability sampling. Data on folic acid and vitamin C intake were obtained using a 24-hour dietary recall method, while tea drinking habits and adherence to TTD consumption were collected through questionnaires. Hemoglobin levels were measured directly using a hemoglobin testing device. Data analysis was performed using the Spearman correlation test. The results showed significant relationships between folic acid intake and hemoglobin levels, vitamin C intake and hemoglobin levels, adherence to iron supplementation and hemoglobin levels, and tea drinking habits and hemoglobin levels, with a negative direction of association. This study concludes that folic acid intake, vitamin C intake, tea drinking habits, and adherence to TTD consumption influence hemoglobin levels in adolescent girls. Efforts to prevent anemia should focus on improving dietary patterns, proper use of iron supplementation, and regulating tea drinking habits.

Social media has become a primary means of communication for adolescents in the digital era, yet excessive use can create complex impacts on their academic, social, and psychological well-being. The positive effects include expanding cross-regional friendships, improving communication skills, strengthening social relationships, and increasing learning motivation through peer interaction and support. Conversely, the negative effects include declining academic performance due to reduced focus, neglect of responsibilities, weakened language skills caused by the dominance of informal language, a higher risk of digital crimes such as fraud and identity theft, as well as mental-health issues including anxiety, depression, social-comparison pressure, and cyberbullying. To minimize these risks, preventive efforts are needed, such as enhancing digital literacy for both adolescents and parents, promoting ethical and safe online behavior, regulating screen time, strengthening parental guidance, implementing digital-wellness policies in schools, providing counseling services, developing more youth-friendly platforms, and enforcing government regulations on online safety. This study emphasizes that the wise, safe, and productive use of social media can only be achieved through collaborative efforts involving adolescents, families, schools, communities, platform providers, and the government.
