GARUDA : Jurnal Pendidikan Kewarganegaraan dan Filsafat 2026 International Forum of Researchers and Lecturers

This study aims to analyze the manifestation of Indonesian unity values within the local wisdom of Kresnayana in Blitar Regency, particularly through the “Hasta Brata” performance. As a multicultural nation, Indonesia possesses diversity that represents both potential and challenge; therefore, strengthening unity values through various media, including local wisdom, is essential. This research adopts a qualitative approach with a phenomenological design to explore the experiences and involvement of cultural actors in the Kresnayana performance. Data were collected through in-depth interviews, documentation, and literature review using snowball sampling techniques, and were analyzed inductively through data reduction, triangulation, data display, and conclusion drawing. The findings indicate that Kresnayana, which originates from the reliefs of Penataran Temple, functions not only as a medium for cultural preservation but also as a means of educating unity values. In the “Hasta Brata” performance, the value of unity is reflected in the complementary relationship between Arjuna and Kresna; the value of togetherness is demonstrated through the cooperation between Anoman and Arjuna; the value of patriotism is evident in efforts to maintain world peace; and the value of Bhinneka Tunggal Ika is illustrated through the unity of characters from diverse backgrounds. Furthermore, the festival serves as a contextual learning medium in Pancasila and Civic Education (PPKn) and supports the strengthening of the Pancasila Student Profile. Thus, Kresnayana represents a concrete manifestation of the implementation of unity values in community life through a local cultural approach.

Christian education plays a strategic role in shaping the faith, character, and spiritual life of learners however, learning processes often remain theoretical, limiting the internalization of faith values. This study aims to examine the concept of theological reflection using the Sharing Christian Praxis (SCP) method in Christian education, explore its application, and analyze its relevance to contemporary life. This research employs a qualitative approach with a literature study method, drawing on relevant books, scientific journals, and academic sources. The findings indicate that theological reflection is a fundamental process in Christian education that enables learners to interpret life experiences in the light of God’s Word, resulting in authentic faith transformation. The SCP method, developed by Thomas H. Groome, provides an operational framework for implementing this theological reflection through systematic stages: sharing life experiences, critical reflection, engagement with Scripture, dialogue, and commitment to action. The relationship between theological reflection and SCP is integral and synergistic; theological reflection provides direction and depth, while SCP operationalizes this process dialogically and contextually, the application of SCP in Christian education has proven effective in increasing learner engagement and connecting faith with daily life. It is recommended that Christian educators implement SCP as a primary learning method, and that educational institutions integrate it into their curriculum development strategies.

The management of essential drug inventory is a strategic component of hospital pharmaceutical services because it directly influences service continuity, cost efficiency, and the overall quality of healthcare delivery. Poor inventory control can result in excessive stock accumulation, increased risk of drug expiration, inefficient budget utilization, and potential drug shortages that may compromise patient care. This study aims to evaluate the effectiveness of essential drug inventory control at Pekerja General Hospital by applying the ABC-VEN, Economic Order Quantity (EOQ), and Reorder Point (ROP) methods. It also examines differences in inventory management efficiency between 2024 and 2025 based on inventory value, cost of goods sold (COGS), and Inventory Turnover Ratio (ITOR). A mixed-methods approach with a sequential explanatory design was used. Quantitative analysis involved a paired sample t-test comparing inventory data from 2024–2025, while qualitative data were collected through in-depth interviews and analyzed thematically using NVivo. The findings reveal a significant improvement in inventory management in 2025 (p < 0.05), reflected in reduced inventory value and COGS, along with an increased ITOR. However, the implementation of ABC-VEN, EOQ, and ROP methods has not been fully integrated, and challenges such as limited human resources and procurement bureaucracy persist.In conclusion, although inventory control became more efficient in 2025, further integration of inventory methods and strengthening of human resource capacity are necessary to ensure sustainable improvements.

This study aims to examine how faith rooted in the family has implications for children's character education. The family is the first and foremost environment in human life, where children begin to learn about life values, including faith, morals, and responsibility. In Christian families, parents play a crucial role in instilling and fostering faith through living examples, praying together, and participating in Church life. This study employed a qualitative research method with a descriptive approach. The analysis was conducted by reviewing various scientific sources and Church documents relevant to the research theme, such as Familiaris Consortio and Amoris Laetitia, which emphasize the role of the family as a "domestic Church." The documents of the Second Vatican Council, as well as relevant journals and books, were also used. The results of the study indicate that faith that lives and grows within the family has a significant influence on the formation of children's character. The values ​​of faith taught within the family, such as love, honesty, responsibility, and concern for others, form an important foundation for developing good character. Through consistent faith education within the family, children can grow into individuals with faith, morals, and the ability to live responsibly in society.

This study explores how social media–driven green marketing shapes sustainable consumer behavior through a systematic literature review. As concerns about sustainability intensify alongside rapid digital engagement, social media has emerged as a crucial platform for communicating environmental initiatives and influencing consumer responses. Despite this relevance, existing studies remain fragmented across theoretical, contextual, and methodological perspectives, limiting a holistic understanding of the topic. Using the PRISMA approach, this research reviews 42 empirical articles sourced from the Scopus database and analyzes them through the TCCM (Theory–Context–Characteristics–Method) framework. The findings show that most studies rely on intention-based theories, particularly the Theory of Planned Behavior, although there is a growing shift toward integrating social, psychological, and technology-oriented approaches. From a contextual standpoint, the literature is largely concentrated in Asian regions and younger demographics, which restricts broader generalization. Furthermore, results indicate that social media–driven green marketing does not directly affect sustainable behavior but works through important psychological mediators such as trust, engagement, and perceived value. These factors significantly influence how consumers interpret and respond to environmental messages online. The effectiveness of such marketing strategies is also shaped by cultural and demographic differences, making context a critical factor. Methodologically, most studies employ cross-sectional surveys and structural equation modeling, limiting the ability to capture causal and dynamic relationships. Overall, this study provides a structured synthesis, highlights research gaps, and suggests future directions, including cross-cultural analysis, stronger theoretical integration, and more rigorous research designs.

This article aims to explore a dialogical reflection on the values of wisdom and leadership between the Bugis local wisdom of Salipuri Temmadinging and the biblical wisdom tradition found in Proverbs 29:14. The study is motivated by the growing leadership crisis in contemporary society, which calls for ethical reflections rooted not only in modern theories but also in local and religious traditions rich in moral insight. Employing a qualitative approach with a literature-based method, this research conducts a critical and comparative analysis of cultural texts on Salipuri Temmadinging and biblical interpretations of Proverbs 29:14. The findings reveal that both traditions emphasize social justice, moral integrity, and advocacy for the poor as essential foundations of stable and legitimate leadership. Leadership is understood not as an instrument of power, but as a moral responsibility to protect, nurture, and sustain communal life. The dialogue between these traditions highlights justice as a structural principle that ensures the durability and credibility of leadership. This study implies that integrating local wisdom and biblical wisdom literature can contribute significantly to the development of ethical and contextual leadership models within Indonesia’s pluralistic society.

This study aims to analyze the contribution and potential of the Lampung Province tourism sector to national economic growth in the 2020-2025 period. Using a quantitative descriptive approach using the Location Quotient (LQ) and Shift Share methods, this study processes secondary data on Gross Regional Domestic Product (GRDP) at constant prices from the Central Statistics Agency. The analysis shows that although Lampung's macroeconomic performance is still dominated by the primary sector, the tourism sector, particularly the accommodation and food and beverage subsector, has demonstrated post-pandemic resilience with a significant positive growth trend. In 2024, the GRDP value of this subsector at the provincial level reached IDR 4,616.76 billion, with strategic areas such as Bandar Lampung City confirming the accommodation sector as a base sector (LQ > 1) with a high competitive advantage. The integration of a creative economy based on local wisdom, such as the use of Tapis cloth and digital marketing, has been proven to increase the attractiveness of destinations, capable of driving the volume of domestic tourist trips to reach 17.87 million trips by 2024. This finding confirms that Lampung's tourism sector is not only a regional economic driver, but also makes a substantial contribution to national income through a multiplier effect on job creation and increasing domestic foreign exchange. Optimizing collaboration between policymakers and accelerating infrastructure development are key to strengthening the strategic position of Lampung tourism in the future.

Vegetables are an important horticultural commodity in fulfilling community nutritional needs; however, their consumption level in Indonesia remains relatively low, necessitating efforts to increase production. Spinach (Amaranthus sp.) is a promising vegetable due to its short growth cycle, ease of cultivation, and high nutritional value. Limited agricultural land, particularly in urban areas, poses a major constraint to conventional cultivation, thereby encouraging the adoption of alternative technologies such as hydroponics. The hydroponic system, especially the Nutrient Film Technique (NFT), offers efficient use of land and water while enabling better control of plant growth. This review aims to identify hydroponic cultivation techniques for spinach in greenhouse conditions and to analyze factors influencing its success, including nutrient concentration, growing media, pH, temperature, and light intensity. The findings indicate that optimal nutrient concentration ranges from 410–900 ppm, supported by proper environmental and pH management to enhance vegetative growth. The implementation of the NFT system improves production efficiency, resulting in more uniform, cleaner, and higher-quality yields. Nevertheless, challenges remain, including nutrient management, environmental fluctuations, and pest and disease risks. Therefore, proper and sustainable system management is essential to ensure successful hydroponic spinach cultivation.

Social media has brought significant changes in the way humans interact, construct meaning, and shape social identities. In Indonesia, TikTok is the most widely accessed social media platform, reaching 32% of users. TikTok is not only a medium of entertainment but also a space for the production and reproduction of values, tastes, and social standards. The TikTok algorithm presents personalized content according to user preferences, creating a continuous flow of information that is visually and repetitively consumed. From an anthropological perspective, this article aims to analyze how algorithms influence the formation of digital identity and generate new status symbols in virtual spaces. This research uses a qualitative approach with ethnographic methods and literature studies on TikTok usage practices. The results of the study show that indicators of popularity such as the number of views, followers, likes, and interaction rates become new forms of status symbols that represent users’ social influence in the digital world. From an anthropological perspective, TikTok can be understood as a new cultural space where algorithms act as structural agents that influence social practices, identity production, and symbolic hierarchies within digital society. This study emphasizes that algorithms function not only as technical technologies but also as cultural forces that shape how individuals understand themselves and their social positions within the social media ecosystem.

. The rapid development of artificial intelligence (AI) has brought significant changes in various fields, including education and church life. This study aims to examine the dynamics of the formation of prospective catechists in facing the challenges of AI use at the IPI Malang Pastoral College. This study used a qualitative, descriptive approach, through observation and interviews with students as research subjects. The results show that the use of AI has become an integral part of the learning process, helping students understand material, develop academic skills, and enhance creativity in the pastoral field. However, the use of AI also poses challenges in the form of a tendency towards instantaneous attitudes and potential dependency that can hinder critical thinking skills and deep reflection on faith. In the context of pastoral education, the formation of prospective catechists emphasizes not only intellectual aspects but also spirituality, personality, and pastoral sensitivity. Therefore, the wise and proportional use of AI is necessary, while still positioning it as a supporting tool, not a substitute for human roles. The role of lecturers and educational institutions is crucial in guiding students to be able to use technology critically, reflectively, and responsibly. Thus, the integration of technology and faith values ​​is expected to produce prospective catechists who are able to respond to the challenges of the times in a relevant and meaningful manner.

The performance of Asphalt Concrete – Wearing Course (AC-WC) is greatly influenced by the characteristics of the mixture, one of which is the void value which plays a role in stability, durability, and resistance to damage. Rainwater is the most dominant environmental factor accelerating pavement damage through stripping mechanisms, bond release, and a decrease in the structural strength of the layer. Therefore, it is necessary to conduct a study on changes in void value with soaking duration, the relationship of void value to the design life of the road pavement, and an empirical model of the design life based on void value with variations in soaking in the mixture using a laboratory test approach. Based on the results of laboratory tests, it can be seen that changes in void values ​​due to variations in soaking time using rainwater indicate that the longer the mixture is soaked, the changes in VIM and VMA values ​​tend to decrease, while VFA increases. The relationship between VIM values ​​and the design life of road pavements in AC-WC layers due to soaking variations shows that the design life decreases sharply when the VIM value is <3%. Thus, long-term immersion can reduce the road life by more than 35% of its ideal design life and based on a simple empirical model equation to estimate the design life of the pavement based on the void value and immersion conditions, N0 = 12.5 years is obtained (Ideal mix design life at VIM = 4%).
