Education is a conscious and structured effort aimed at creating an environment and process that actively facilitates learners in developing their full potential. This includes nurturing their spiritual and moral values, self-control, intelligence, strong character, and essential life skills required for personal development and meaningful contributions to society, the nation, and the global community. At its core, education serves to empower students to realize and utilize their capabilities for future life challenges. It acts as a foundational medium through which younger generations acquire essential life skills, enabling them to integrate effectively into society. Moreover, education plays a pivotal role not only in the personal growth of individuals but also in the advancement of a nation. High-quality education is defined by its capacity to equip students with the competence to confront and resolve real-world problems. This notion becomes increasingly critical as learners transition from academic settings to the workforce and community life, where they are expected to apply their knowledge and skills practically. However, the success or failure of educational outcomes is largely determined by the curriculum. A well-designed curriculum should cultivate critical awareness and empower students to navigate complex social and professional environments. It should also promote creativity, critical thinking, and collaboration, which are essential skills in today’s rapidly changing world. Furthermore, education should not be viewed merely as a means to acquire knowledge but as a holistic process that fosters emotional intelligence and social responsibility. By integrating various disciplines and encouraging interdisciplinary learning, education can help students develop a broader perspective on global issues, such as climate change, social justice, and economic inequality. In addition, the role of educators is crucial in this process.

This study aims to comprehensively examine the concept of gratitude (shukr) from the perspective of the Qur'an by employing a thematic interpretation approach ( tafsīr al-maw ḍ ū'ī ) combined with the grounded theory method. This dual approach allows for an in-depth exploration of Qur'anic verses related to gratitude while also constructing theoretical frameworks derived directly from the primary data—namely, the Qur'anic text itself. The research adopts a qualitative, library-based methodology, where relevant verses are collected, categorized, and regularly analyzed to understand how gratitude is depicted, what forms it takes, and how it influences human life. The findings reveal that gratitude in the Qur'an goes beyond verbal expressions of gratitude to God. It encompasses inner awareness, acknowledgment of divine favor, wise utilization of blessings, and concrete actions that reflect obedience to God. Gratitude is presented as an active response to divine grace, resulting in positive behavior, spiritual closeness, and the strengthening of ethical and social dimensions in a believer's life. Moreover, the Qur'an affirms that those who are grateful are not only spiritually elevated but also promised an increase in blessings and a noble status in the sight of God. In the current socio-religious context, the value of gratitude holds significant relevance as a foundation for character development and emotional resilience. This study affirms that gratitude is a universal Islamic value that integrates theological, psychological, and ethical aspects. Thus, it is expected that this research contributes both theoretically and practically to the development of thematic Qur'anic studies and a deeper understanding of spiritual consciousness.

This study aims to analyze the factors influencing the optimization of green open space (GOS)-based tourism object development at Panatapan Panyabungan Park, Mandailing Natal Regency. This area possesses high ecological and visual potential, yet its management remains suboptimal in terms of facilities, community participation, and institutional support. The study employs a mixed methods approach, combining quantitative methods using multiple linear regression analysis on 150 respondents, and qualitative methods through in-depth interviews with key informants. The results show that simul-taneously, the four independent variables—GOS quality (X1), tourism facilities and infrastructure (X2), community participation (X3), and local government support (X4)—significantly influence the optimization of tourism development (Y). However, partially, only X2 has a significant positive effect, while X1 and X3 have significant negative effects, and X4 has no significant effect. Qualitative findings reveal that the community is not involved in decision-making, and the local government has not demonstrated concrete intervention in managing the area. These findings suggest that the strategy for developing GOS-based tourism objects should emphasize improving basic facilities, establishing participatory governance, and strengthening the structural role of local governments. A collaborative and community-based approach is key to realizing a sustainable tourism area in environmental, social, and economic aspects.

This research is an evaluative study of the old urban area of Kesawan in Medan City, which has been part of the city’s revitalization efforts initiated by the Medan City Government. Kesawan possesses strong historical and colonial architectural character but has undergone functional and visual degradation due to uncontrolled modern urban development. One of the key issues identified is the presence of inactive urban spaces, disconnected from the public realm and lacking social meaning—phenomena recognized in urban theory as lost space. This concept serves as the foundation for evaluating the effectiveness of the revitalization program implemented since 2021. The study employs a qualitative approach using a single-case study method, focusing on Kesawan as a complex urban space. Data were collected through field observations, in-depth interviews with five categories of informants (building owners, visitors, security personnel, street vendors, and architects), and visual documentation. The analysis adopts the theoretical framework of Finding Lost Space by Roger Trancik (1986), which comprises three main approaches: Figure-Ground Theory, Linkage Theory, and Place Theory. These were further elaborated into six evaluative indicators: connectivity, continuity and circulation, enclosure, accessibility, visual orientation, and the meaning and perception of space by the public. The findings indicate that revitalization has brought significant visual improvements and physical enhancements, particularly along the main corridor of Jalan Ahmad Yani I–VII. However, many secondary streets and non-priority areas still exhibit characteristics of lost space, such as disconnected pedestrian paths, underutilized voids, weak spatial integration, and limited social engagement. These conditions suggest that the revitalization outcomes remain uneven and predominantly cosmetic in certain areas. The study recommends integrating spatial and social approaches in future urban revitalization policies to ensure that public space functions can be restored holistically, sustainably, and contextually in line with local identity.

Lau Kawar Lake, a natural tourism area located on the slopes of Mount Sinabung in Karo Regency, North Sumatra, holds significant potential for the development of nature and culture-based tourism. However, the growth in tourist visits has not yet met expectations due to limited accessibility across various dimensions. This study aims to formulate strategies for improving physical, informational, and institutional accessibility in support of sustainable regional development.The research adopts a mixed methods approach, emphasizing primary data collection through field observations, interviews with key stakeholders and village officials, as well as surveys of 60 tourist respondents. Findings reveal that, overall, the three dimensions of accessibility are still rated as "fair," with average scores ranging from 3.28 to 3.36. The main barriers identified include inadequate road infra-structure within the area, lack of dedicated public transportation for tourists, limited official digital promotional content, and weak institutional coordination in area management. A synthesis of the quantitative and qualitative results indicates that the development of Lau Kawar Lake requires an integrative approach that combines spatial planning, community-based governance, and local policy interventions.Based on these findings, several strategic recommendations are proposed: (1) improvement of access roads and landslide-prone areas through Special Allocation Fund (DAK) for infrastructure; (2) provision of dedicated public transportation for tourists with fixed routes and schedules from the nearest city center; (3) installation of directional signs and visual information boards in aesthetically pleasing formats and bilingual language; (4) establishment of a Digital Promotion Team involving local actors and institutions; (5) capacity-building programs for the community in tourism services, home stay management, and culinary entrepreneurship; and (6) formation of a Cross-Sectoral Accessibility Coordination Forum for Lau Kawar Tourism as a medium-term planning and monitoring platform.This study contributes contextually to strengthening the accessibility dimension as a key prerequisite for advancing local tourism destinations towards sustainable, inclusive, and locally grounded development.

Mursala Island is one of the potential coastal tourism areas in Central Tapanuli Regency, known for its natural uniqueness and rich local culture. However, tourism development in this area re-mains unstructured and unsustainable. This study aims to analyze the current conditions, infrastructure readiness, accessibility, community participation, and the level of local socio-cultural resilience toward tourism in order to formulate strategies for sustainable coastal tourism development. A mixed-methods approach was employed, with primary data collected through observation, in-depth interviews, and a questionnaire distributed to 100 respondents.The results show that local socio-cultural resilience is the most strategic variable in supporting tourism interest (mean = 4.06), followed by community participation (3.82), infrastructure readiness (3.61), and accessibility (3.26). Qualitative findings reinforce these results, revealing that while the community actively maintains cultural traditions, they face access barriers and lack participatory institutions. A SWOT analysis led to realistic strategies such as establishing a Local Customary Tourism Unit, developing permanent piers and sea transportation, and drafting a village regulation (Perdes) on culture-based tourism.This study concludes that sustainable coastal tourism development in Mursala Island must be grounded in the strength of local social capital, cultural preservation, and improvements in accessibility and infrastructure. The findings contribute theoretically to strengthening the concept of Community-Based Tourism (CBT) and practically to informing policy direction for locally-based coastal tourism area development.

Changes in building functions in urban areas have become an inevitable phenomenon, especially in developing cities such as Binjai City. This study aims to analyze the factors influencing building function changes in the area, using a Mixed Methods approach that combines quantitative analysis through multiple linear regression and qualitative documentation based on field observations. Four independent variables were examined: inconsistency with the Spatial Plan (RTRW), accessibility, economic motivation, and law enforcement.The results show that economic motivation and accessibility have a significant influence on building function changes. Meanwhile, the variables of RTRW inconsistency and weak law enforcement did not show statistically significant effects. These findings are supported by visual field evidence indicating a massive conversion of building functions without effective spatial planning control. Photographic documentation reveals a tendency among the community to adapt building functions for economic activities in strategically accessible areas.The study concludes that building function changes in Binjai City are driven by economic needs and urban spatial dynamics that are not matched by supervision and enforcement of spatial planning regulations. Recommendations include strengthening spatial supervision, providing socio-economic-based incentives, simplifying permit processes, and implementing community-based public education. This research offers valuable contributions to adaptive urban planning while upholding the principles of spatial order and community aspirations.
