Abstract:This study examines the development of the Rammang-Rammang karst landscape in Maros Regency, South Sulawesi, into a prominent ecotourism destination, through an anthropological perspective. Utilizing qualitative methods—including…
��including in-depth interviews, participant observation, and focus group discussions—this research explores how the local community navigates the rapid shift from a traditional agrarian and riverine lifestyle to a tourism-based economy. Anthropological analysis reveals that while ecotourism provides alternative livelihoods and fosters local pride, it also introduces challenges regarding cultural commodification, shifts in communal values, and spatial contestation. The findings indicate that the local community exercises significant agency by integrating their ancestral kinship networks (siri’ na pacce) into modern tourism management. This cultural adaptation serves as a mechanism for community resilience, ensuring that external commercial pressures do not fully erode local identity. This study concludes that sustainable tourism development in heritage sites like Rammang-Rammang depends on recognizing local communities not merely as stakeholders, but as active cultural custodians of the karst landscape

ve approach. Data were collected through interviews, observations, and documentation. The study analyzes organizational effectiveness based on four indicators: Human Relations (focusing on organizational involvement), Open System Model (adaptation and innovation), Internal Process Model, and Rational Goal Model (productivity and goal achievement). The results show that in Kampung Jaya Makmur, the head of the farmer group association has never conducted socialization or training for farmer groups on how to produce or provide natural fertilizers using locally available materials, despite the uncertainty of continuous fertilizer supply. The effectiveness of farmer group associations in empowering the community is highly needed to support farmers in becoming more independent. Farmer group associations can provide services such as access to technological information and capital, as well as establish partnerships with external parties. This study recommends that farmer group associations strengthen participation and member involvement through more regular deliberation forums and active engagement of all levels of farmers. It also emphasizes the need to enhance the use of technology and alternative agricultural methods, such as organic fertilizers, and to expand training and mentoring programs so that farmers can reduce their dependence on chemical fertilizers.

Abstract:This research discusses the influence of social media content on the emergence of Fear of Missing Out (FOMO) behavior and its connection to increasing consumerism in Generation Z. This generation grew up in a digital ecosystem…
system saturated with visualizations of ideal lifestyles disseminated through platforms like TikTok, Instagram, and Twitter. Constant exposure to such content creates anxiety about missing out on seemingly important social experiences. FOMO then triggers consumptive actions, not due to functional needs, but because of symbolic impulses and social pressure to remain relevant within digital communities. This study employs a descriptive qualitative method with in-depth interviews of informants aged 20–26 years. The analysis results show that content such as unboxing, product reviews, and personal lifestyles have a significant impact on creating social pressure and shaping consumption-based identity. These findings underscore the importance of digital literacy and critical awareness so that Generation Z does not get trapped in a cycle of impulsive consumption, which poses risks to both mental and financial health. As an alternative, the Joy of Missing Out (JOMO) approach is introduced to build healthier and more authentic digital relationships.
Abstract:The development of digital technology has brought significant changes to Sunday School ministry and children’s faith education in the modern era. Children, as digital native generations, are increasingly connected to visual…
isual media, audiovisual content, and internet use, causing conventional learning methods to become less engaging and less effective in fostering active learner participation. This study aims to analyze Sunday School strategies in addressing the opportunities and challenges of digitalization, the utilization of digital media for children’s spiritual growth, and the roles of teachers, churches, and families in developing relevant and transformative spiritual learning. The research employed a qualitative approach with a library research design enriched through phenomenological analysis of digitalization practices in Sunday School ministry. Data were obtained through a review of literature on Christian educational theology, child pedagogy, digital literacy, and reflective observation of the use of Bible animation videos, social media, and online learning platforms. The findings indicate that the digitalization of Sunday School ministry through Bible animation videos, YouTube, Zoom, Google Meet, and Christian learning applications enhances children’s interest, participation, and understanding of God’s Word through learning experiences that are more interactive, communicative, and contextual. The challenges of digitalization are reflected in gadget-related distractions, digital dependency, reduced learning concentration, and unequal access to technology among certain families. The study concludes that the success of digital Sunday School requires the integration of technology, teacher competence, parental guidance, digital literacy, and continuous spiritual formation. The novelty of this study lies in the development of a digital Sunday School ministry model that integrates technological media, pedagogical strategies, family supervision, and children’s spiritual formation in a holistic manner, thereby ensuring that church ministry remains adaptive, inclusive, and centered on children’s faith development in the digital era.
Abstract:Educational program evaluation serves as a strategic element to ensure the improvement of learning quality at the elementary school level, particularly as schools are required to be adaptive to students’ diverse learning…
ng needs. A major issue frequently encountered is teachers’ limited capacity to implement evaluation models that are simple, sustainable, and relevant as a basis for instructional decision-making. This study aims to analyze the application of simple evaluation through formative and summative approaches as a systematic effort to enhance the quality of learning in elementary schools. The formative approach is employed throughout the instructional process to provide immediate feedback, identify students’ learning difficulties, and adjust teaching strategies in real time, while the summative approach is applied at the end of the instructional period to assess the level of goal attainment and the overall effectiveness of the program. The findings indicate that a balanced implementation of both approaches enables teachers to design learning activities that are more responsive, measurable, and oriented toward continuous improvement. Practically designed simple evaluations also encourage teachers to take an active role as controllers of learning quality rather than merely as curriculum implementers. The conclusion of this study confirms that the integration of formative and summative evaluation in a simple yet systematic manner effectively improves learning quality while strengthening a reflective culture in elementary school settings. The novelty of this study lies in its emphasis on an evaluation model that is easy to apply, contextual, and oriented toward teachers’ daily pedagogical decision-making, thereby offering a practical alternative for elementary schools with limited formal evaluation resources.

ct concepts in science subjects. These limitations necessitate innovative learning media capable of optimizing information processing through alternative sensory modalities, namely auditory and tactile. Audio-tactile media represents an innovation that simultaneously integrates sound and touch stimulation to facilitate multisensorial conceptual understanding and enhance the cognitive construction of visually impaired students. This study employs a qualitative descriptive approach utilizing observation, in-depth interviews, and documentation techniques to evaluate the effectiveness of audio-tactile media in the context of science learning within inclusive classrooms. The results indicate that audio-tactile media significantly improves conceptual understanding, learning motivation, and active participation among visually impaired students. Additionally, this media strengthens social interaction among students and supports teachers in delivering material inclusively and responsively to individual learner needs. The novelty of this research lies in the application of learning media that combines two sensory modalities as an innovative pedagogical strategy to overcome cognitive barriers caused by visual impairment, while simultaneously enriching the multisensorial learning experience. These findings contribute significantly to the development of an adaptive, inclusive, and equitable science learning model for students with special needs. Accordingly, audio-tactile media is recommended as an effective alternative to create an inclusive and high-quality learning environment.
