This study aims to analyze in-depth cognitive learning theory and its implications for improving the effectiveness of Islamic Religious Education (PAI) teaching at the elementary school level. The adopted methodological approach is qualitative through library research, with the application of content analysis and theoretical synthesis techniques. Primary data sources were obtained from academic literature including textbooks, scientific journals, and the latest empirical research relevant within the last decade. The results of the analysis indicate that cognitive learning theory positions cognitive processes as the core of learning activities, allowing students to function as active agents in constructing knowledge through understanding, analysis, memory representation, and integration with pre-existing cognitive schemas. In the context of PAI, this approach enables meaningful learning through interactive pedagogical strategies such as collaborative discussions, problem-solving, case studies, and metacognitive reflection, which are empirically adapted to the stages of students' cognitive development. The implementation of cognitive theory significantly contributes to strengthening conceptual understanding, increasing learning engagement, developing critical thinking skills, transferring knowledge, and internalizing Islamic values. Thus, cognitive learning theory makes a substantial contribution to optimizing the effectiveness of PAI teaching in elementary schools through an interactive, systematic, and understanding-oriented approach.

This study aims to analyze the effect of cutting parameters on surface roughness in the turning process of AISI 1045 steel. The investigated parameters include cutting speed, feed rate, and depth of cut. A quantitative approach was employed using multiple linear regression analysis with SPSS software. The dataset consisted of 30 simulated experimental observations with varying cutting parameter conditions. Prior to regression analysis, classical assumption tests including normality, multicollinearity, and heteroscedasticity tests were conducted to ensure the validity of the model. The results indicated that all assumptions were satisfied. The findings reveal that simultaneously, all independent variables have a significant effect on surface roughness with a coefficient of determination of 82.1%. Partially, Feed rate and cutting speed significantly influence surface roughness, while depth of cut does not show a significant effect. Feed rate is identified as the most dominant variable affecting surface roughness, where an increase in Feed rate leads to higher roughness values. In contrast, increasing cutting speed tends to reduce surface roughness. This study highlights the importance of controlling cutting parameters, particularly Feed rate and cutting speed, to improve machining quality. The results provide practical implications for manufacturing industries in optimizing machining parameters to achieve better surface quality and process efficiency.

This article examines the urgency of strengthening Islamic creed (aqidah) as a preventive instrument in addressing religious radicalism. The rise of extremism is not merely driven by sociological factors, but is also rooted in a theological crisis, namely textual interpretations that give rise to exclusivism and takfiri doctrines. Employing a conceptual literature review method, this study deconstructs the pathology of radicalism and reconstructs the preventive dimensions of aqidah. The findings reveal that ideological mitigation is grounded in three dimensions of aqidah: Tawhid as a means of liberating reason from group arrogance, wasathiyyah (moderation) in maintaining tolerance, and the absolute integration of faith with social morality. To be effective, these values must be institutionalized within Islamic education through the transformation of critical pedagogy, the strengthening of religious digital literacy, and the development of an inclusive school culture. Strengthening aqidah is therefore not merely a transfer of dogma, but the formation of a moderate worldview as a strong shield against the infiltration of radical ideologies.

Multicultural education offers hope in addressing various social tensions that have emerged in recent times, as it is an educational approach that consistently upholds values, beliefs, heterogeneity, plurality, and diversity in all aspects of education. This study aims to describe the implementation of multicultural inclusive learning in developing students’ moral character and to identify the challenges of its implementation at MIN 2 Gunungkidul Yogyakarta. The study employed a qualitative approach with a case study design. Data were collected through observation, interviews, and documentation involving the principal, teachers, and students as sources of information. The data were analyzed through data collection, data reduction, data display, and conclusion drawing or verification. The findings show that multicultural inclusive learning was implemented through the habituation of the 5S values (smiling, greeting, addressing, politeness, and courtesy), inclusive classroom arrangement for students with special needs, and the strengthening of discipline, responsibility, independence, care, and religious activities within the madrasah environment. These practices contributed to a warmer learning atmosphere, acceptance of differences, and social interaction between regular students and students with special needs. The main challenges included the limited availability of special assistant teachers, teachers’ limited competence in handling students with special needs, and insufficient inclusive learning facilities

This article examines the use of cooperative learning strategies in Christian Religious Education (CRE) as an instructional approach that emphasizes the strengthening of students’ faith and Christian character. The discussion covers the definition, objectives, conceptual foundations, principles, and operational procedures of cooperative learning, which are then connected to the theological goals of CRE. The study employs a qualitative approach using a library research method, analyzing pedagogical and theological literature to construct a conceptual framework for implementing cooperative learning within the context of CRE. The findings indicate that cooperative learning strategies are highly aligned with the essence of CRE, as they foster dialogical interaction, shared responsibility, empathy, and the internalization of Gospel values through collaborative learning processes. The effective implementation of this strategy can create a participatory, reflective, and formative learning community that enhances not only cognitive understanding but also students’ attitudes, spirituality, and Christian character. This research is significant in providing both theoretical and practical foundations for CRE educators in designing learning experiences that are relevant, relational, and transformative in accordance with the goals of faith formation.

Cutaneous fungal infections caused by Malassezia furfur remain a significant health concern in tropical regions, highlighting the need for safe and effective alternative therapies. Moringa oleifera L. leaves are reported to contain various secondary metabolites, including flavonoids, tannins, and saponins, which exhibit potential antifungal activity. This study aimed to develop a topical suspension formulation of Moringa oleifera leaf extract and to evaluate the effect of varying extract concentrations on the physical characteristics of the preparation. An experimental method was employed using four formulations: F0 as the control, and F1, F2, and F3 containing 9%, 10%, and 11% extract, respectively. Evaluation parameters included organoleptic properties, homogeneity, pH, viscosity, and adhesiveness, as well as stability testing using a cycling test method for 12 days. The results demonstrated that all formulations exhibited good organoleptic characteristics, homogeneity, and viscosity. The pH values remained within the acceptable range for skin preparations, although slight fluctuations were observed during storage. Adhesiveness also showed variations across several testing cycles. Overall, the formulations met acceptable physical quality criteria and demonstrated potential for further development as topical suspensions; however, formulation optimization is still required to enhance stability during storage.

The Celeng Behel tradition is a form of local wisdom practiced by the people of Soropadan Village, Pringsurat District, Temanggung Regency, and is carried out through the Sadranan Kali ritual. This study aims to explain the form and function of the Celeng Behel tradition in the community’s daily life. The research uses a qualitative descriptive method with folklore and semiotic approaches. Data were collected through interviews, observations, and documentation, then analyzed to understand the cultural meanings behind the tradition. The results show that the Celeng Behel tradition has two main forms. First, it exists as oral folklore in the form of stories passed down from generation to generation. Second, it appears as a ritual practice, namely Sadranan Kali, which is held every year on the 10th of Sapar at Bendung Pondoh. The ritual includes communal prayers, the preparation of offerings, and the release of ducks into the river. These activities symbolize the community’s gratitude for the water that supports their farming and daily needs. The tradition also has important functions. It serves as a way for the community to express their hopes and concerns about nature, especially related to water and agriculture. It also strengthens social rules and cultural values that have been passed down over time. From a semiotic point of view, the symbols used in the ritual have both direct meanings and deeper cultural meanings that form shared beliefs in the community. In conclusion, the Celeng Behel tradition is not only a cultural activity, but also an important way to maintain harmony between humans, nature, and spiritual values in the life of the Soropadan community.

. The effort to re-visualize regional architectural elements combined with modern touches is known as neo-vernakular architecture. In North Sumatra, there are various ethnic groups, including Batak, Mandailing, Malay, and others, each possessing rich traditional architectural values. This study aims to identify and analyze traditional architectural elements applied to the façade of the North Sumatra Regional House of Representatives (DPRD) building. The DPRD North Sumatra building is one of the government buildings that functions as a workplace for representatives of the people, council members, and the secretariat in carrying out governmental duties and public services. The building is located on Jalan Imam Bonjol with an area of approximately 8,000 square meters. This study uses a qualitative descriptive method with data collection techniques through direct field surveys and literature studies related to the façade design of the DPRD North Sumatra building. The results show that the neo-vernakular character on the building façade is represented through several architectural elements, such as exposed columns, sunshading, opening forms, and other supporting elements that reflect a combination of traditional and modern architectural features.  

Bank stock price prediction is an important topic in the application of information technology because stock price movements are dynamic, sequential, and influenced by historical market patterns. This study aims to predict Indonesian banking stock prices using the Long Short-Term Memory method and evaluate the effect of Bayesian Optimization on model performance. The data used in this study consists of daily historical stock data of BBCA, BBNI, BBRI, BBTN, and BMRI from May 4, 2020, to May 4, 2026, obtained from Yahoo Finance. The input features include opening price, highest price, lowest price, closing price, and trading volume, while the prediction target is the stock closing price. The results show that the baseline model produced MAPE values ranging from 1.892% to 3.147%. The best baseline performance was obtained on BBCA with an R² value of 0.933, followed by BBTN with an R² value of 0.902. After optimization, performance improvement occurred on BBTN, with MAPE decreasing from 3.147% to 2.482% and R² increasing from 0.902 to 0.935. For BMRI, MAPE decreased from 2.385% to 2.206%, and R² increased from 0.687 to 0.743. This study concludes that Long Short-Term Memory can be used to predict Indonesian banking stock prices, while Bayesian Optimization can selectively improve model performance depending on the characteristics of each stock dataset.

This study analyzes the integration of aesthetics and ethics in cosmetology education and its implications for strengthening the professionalism of cosmetology teachers. Cosmetology is often viewed as an applied field that primarily produces visual beauty through make-up, skin care, hair care, and cosmetic services. However, professional cosmetology practice also involves moral responsibility because it deals directly with the human body, personal identity, safety, comfort, and client trust. This article uses a normative qualitative method with conceptual and philosophical approaches through library research. The analysis is organized through three dimensions of philosophy of science: ontology, epistemology, and axiology. The findings show that, ontologically, cosmetology studies beauty and the human body not merely as physical objects, but as subjects with value, dignity, and diverse meanings. Epistemologically, cosmetology knowledge is constructed through the integration of scientific theory, practical skills, professional experience, sanitation principles, occupational safety, and service standards. Axiologically, cosmetology contains ethical values that guide beauty practices so that they remain honest, safe, responsible, and respectful of human dignity. The integration of aesthetics and ethics strengthens the role of cosmetology teachers as educators, professional models, and character builders in vocational education. Therefore, cosmetology learning should not only emphasize technical competence and visual results, but also internalize ethical awareness, reflective judgment, and responsibility in every stage of professional practice.

This study aims to map the trends, integration forms, effectiveness, and contribution of ethnomathematics in elementary school mathematics learning toward national cultural preservation. A systematic literature review (SLR) approach following the PRISMA 2020 protocol was employed. Searches across four academic databases (Scopus, Google Scholar, CrossRef, and Semantic Scholar) yielded 1,176 articles, from which 30 articles met the inclusion criteria. Results indicate that ethnomathematics research in elementary schools has increased significantly during 2023–2026, particularly following the implementation of Kurikulum Merdeka. The three most dominant forms of integration are digital modules and media (53.3%), traditional games (33.3%), and ethnomathematics-based worksheets (13.3%). Geometry and measurement is the most researched mathematics topic (50.0%), and conceptual understanding shows the most significant improvement (40.0%). Beyond improving mathematics achievement, ethnomathematics integration contributes to cultural preservation through cultural contextualization in learning (60.0%), strengthening cultural identity and values (26.7%), and active local cultural preservation (10.0%). The study recommends teacher training, curriculum policy strengthening, cross-sector collaboration, and further research to sustain ethnomathematics implementation in Indonesian elementary schools.

This study aims to examine the role of the government in implementing gender political education in schools in Bengkulu Province. Within the context of Indonesia's national education system, gender equality remains a crucial issue that requires sustained attention, particularly in formal educational institutions. As the primary policymaker, the government plays a strategic role in ensuring that educational policies, curricula, teaching practices, and school environments promote the principles of gender equality and inclusiveness. This research employs a library research method by reviewing various scientific publications, policy documents, laws and regulations, government reports, and relevant academic sources related to gender and education. The findings reveal that the government has introduced several regulations and programs to support gender-responsive education and enhance equal opportunities for all students. However, the implementation of these policies in schools across Bengkulu Province continues to face significant challenges. These include limited teacher competence in gender-sensitive instruction, inadequate availability of gender-responsive learning materials, insufficient monitoring and evaluation mechanisms, and the persistence of patriarchal cultural values that influence educational practices. Therefore, this study recommends strengthening policy implementation, providing continuous gender-based teacher training, developing inclusive learning resources, and integrating gender political education into local curriculum content to promote greater gender awareness and equality in schools throughout Bengkulu Province.

Rapid population growth in Sidoarjo Regency has triggered massive land-use changes, resulting in increased surface runoff and reduced performance of the drainage system. This study aims to evaluate the hydraulic capacity of drainage channels in the Pondok Sidokare Indah Housing area against design flood discharges with return periods of 2, 5, and 10 years. The method used is a descriptive quantitative approach, involving hydrological analysis using maximum daily rainfall data from 2015–2025 and hydraulic modeling of the existing channel along 350 meters. The frequency analysis results indicate that the Log Pearson Type III distribution is the most suitable method based on statistical parameters and the Smirnov-Kolmogorov goodness-of-fit test. The calculation of design flood discharge using the rational method yields values of 0.749 m³/s (2-year), 1.003 m³/s (5-year), and 1.164 m³/s (10-year). Meanwhile, the maximum capacity of the existing channel ranges only between 0.534 m³/s and 0.733 m³/s. The comparison between hydrological load and channel capacity shows that all observation points (Sta 0+000 to Sta 0+350) are in overflow condition, even for the lowest return period flood discharge. This condition confirms that the current channel dimensions are no longer adequate and require normalization to mitigate annual flooding in the area.

This study was conducted to examine the integration of spiritual intelligence into Islamic Religious Education (PAI) learning as an effort to strengthen students’ character. At MA Al-Amien Bugih Pamekasan, some students still demonstrate a lack of discipline, responsibility, and honesty in the learning process. To address these issues, PAI teachers integrate spiritual values through religious activities and the cultivation of positive habits during classroom instruction. This study aims to describe the implementation of spiritual intelligence integration, the strategies used by teachers, and its implications for students’ character development. This research employed a descriptive qualitative approach. Data were collected through observations, interviews, and documentation involving purposively selected informants, namely PAI teachers and students. Data analysis followed the Miles, Huberman, and Saldana model, including data reduction, data display, and conclusion drawing. The validity of the findings was ensured through source and technique triangulation. The results indicate that the integration of spiritual intelligence in PAI learning has been implemented systematically through planning, implementation, and evaluation stages. Teachers incorporate spiritual values through religious practices, role modeling, learning reflections, discussions of moral values, and character assessments. These strategies contribute positively to the development of students’ character, particularly in fostering discipline, responsibility, honesty, cooperation, empathy, and independence. Although several challenges remain, including differences in students’ backgrounds, limited instructional time, and external environmental influences, the integration of spiritual values continues to support sustainable character development among students. The findings highlight the important role of spiritual intelligence in creating meaningful learning experiences and promoting positive character formation in Islamic educational settings.

This study aims to analyze the forms of tasybīh ḍimnī in Dīwān al-Imām al-Syāfi‘ī by Imam al-Shafi‘i, identify its elements (musyabbah, musyabbah bih, and wajh al-syabah), and examine the Islamic educational values contained within it. This research employs a descriptive qualitative approach using the content analysis method. The data consist of poetic verses containing tasybīh ḍimnī, focusing on 10 representative stanzas selected from 279 poems. The results show that tasybīh ḍimnī is an implicit form of simile that does not explicitly employ comparative particles, but is instead understood through contextual meaning relations. From the perspective of balaghah, this form is characterized by its implicit and argumentative nature, as well as its ability to construct meaning through logical analogy. The elements of tasybīh can still be identified through meaning reconstruction, even though they are not directly stated. Furthermore, the study reveals Islamic educational values encompassing the dimensions of īmān, islām, and ihsān. The value of īmān is reflected in dependence upon Allah, the value of islām in social life practices, and the value of ihsān in the cultivation of moral virtues such as patience and qanā‘ah (contentment). Thus, tasybīh ḍimnī functions not only as an aesthetic element, but also as an integrative educational medium.

This study aims to examine the development of teachers’ multicultural competence at SMA Ta'miriyah Surabaya. The study employed a qualitative approach using a case study design. Data were collected through interviews, observations, and documentation involving the principal and teachers as research informants. Data analysis applied the interactive model of Miles, Huberman, and Saldana, which consisted of data condensation, data display, and conclusion drawing. The findings revealed that the development of teachers’ multicultural competence at SMA Ta'miriyah was carried out through three main pathways. First, training programs that implicitly integrated multicultural values into general educational programs, such as the teacher mobilization program. Second, organizational development grounded in Islamic values as the foundation for fostering tolerance and respect for diversity, implemented through curriculum integration, school regulations, teacher role modeling, and collaboration among teachers. Third, career development, which remained primarily focused on academic aspects and had not explicitly incorporated indicators of multicultural competence. Teachers’ multicultural competence at SMA Ta'miriyah was reflected in three main dimensions. In terms of knowledge, teachers acquired understanding through teaching experience, formal education, and training. In terms of attitudes, teachers demonstrated tolerant and inclusive behavior when interacting with students from diverse cultural and ethnic backgrounds. In terms of skills, teachers were able to manage classroom diversity harmoniously through adaptive and responsive pedagogical approaches that accommodated students’ differences.

Geometry learning at the Junior High School (SMP) level frequently faces challenges due to the abstract nature of the objects, which impacts students' low spatial literacy. This issue is exacerbated by the dominance of conventional teaching methods that lack interactive digital media. This community service activity aims to enhance students' spatial literacy at SMP IT Qoshrul Muhajirin through learning assistance using ethnomathematics-based digibooks. The method employed consists of four stages: Planning, Acting, Observing, and Reflecting. Data were collected through observation, student response questionnaires, as well as pre-test and post-test instruments. The results indicate a significant improvement in students' spatial literacy by 22.70%, with the average score increasing from 43% in the initial stage to 65.70% following the assistance. Furthermore, 91.3% of students provided positive responses regarding the ease of use of the media, and 90.4% felt more motivated in learning. It can be concluded that the use of ethnomathematics-based digibooks is effective as an innovative learning solution capable of integrating digital technology with local cultural values to optimize students' spatial abilities.

Human happiness does not lie in physical pleasure, victory, wealth, honour, worldly power, a beautiful body, or the senses. People in religious communities seek something deeper, contemplating and acknowledging the highest value in union with God. Thomas Aquinas, in his Summa Contra Gentiles, arguments that human happiness lies in the contemplation of God, through which one attains peace and fulfilment in total self-surrender to God. However, in the lived experience of religious communities, a fear of matters related to sexuality is evident. Indeed, some misunderstand and misinterpret these matters, resulting in monks and nuns who become cold, dry, and rigid, acting in ways that violate sexual morality, thereby disrupting or even destroying—their ministry due to such improper conduct. Based on this, the author recognises the importance of education and the appreciation of sexual values for religious communities. Using a literature review method involving relevant books, journals, articles, and Church documents with a theological approach, it was found that the education of religious people requires aspects of happiness and sexuality education. The results of the study indicate that Thomas Aquinas’s concept of happiness can bridge religious life with sexuality education, which is one aspect that must be understood and lived out. Therefore, the happiness of love and the sexuality education of religious people need to be explored and lived out in the course of living and experiencing life as a religious person.

The role of citizenship education is fundamental in internalizing the values of nationalism and ethics within a society. This research is motivated by the increasing challenges of globalization and moral degradation that threaten the national identity of the younger generation. The primary objective of this study is to analyze the strategic role of citizenship education in shaping and strengthening national character within the Indonesian context. The research employs a qualitative descriptive method, utilizing literature reviews and thematic analysis of educational policies and social phenomena. The findings indicate that citizenship education serves as a vital instrument not only for transferring political knowledge but also for fostering civic disposition, including integrity, tolerance, and social responsibility. Furthermore, the integration of local wisdom within the curriculum significantly enhances the effectiveness of character building. The implications of this study suggest that a revitalized citizenship education curriculum, which adapts to digital era challenges, is essential for maintaining social cohesion. Stakeholders in the education sector must prioritize interactive and participatory pedagogical approaches to ensure that national character values are not merely memorized but practiced in daily life, thereby ensuring the long-term sustainability of the nation's democratic values.
