Abstract

21st-century skills that students need to have are creative thinking skills and digital literacy. Efforts to improve creative thinking skills and digital literacy can be done through the development of Augmented Reality (AR)-based learning media. Augmented Reality is a current technology that combines real objects (the physical world) with the digital world and will obtain clear and detailed information from objects that are made as if alive. In the field of education, the use of Augmented Reality can produce interesting learning media and facilitate the student learning process. Based on the results of observations conducted on students, the empowerment of creative thinking skills and digital literacy has not been optimally implemented. However, basically the school has recognized the importance of empowering creative thinking skills and digital literacy for students. Creative thinking skills and digital literacy that have not been optimally implemented are not supported by the availability of learning media, especially in science subjects that are in accordance with facts or real objects around them. Creative thinking skills and digital literacy are not optimal and there is no development of science learning media that activates students so that researchers conducted research to develop AR learning media. The purpose of this research is to develop AR-based science learning media to improve creative thinking skills and digital literacy of eighth-grade students. The research and development method is the Lee and Owens method. Results indicate AR learning media developed can improve creative thinking skills and digital literacy of grade 8 students.

Abstract

This study aimed to analyze the marketing efficiency of buffalo livestock in the cultural context of Kodi, Kodi Bangedo District, Southwest Sumba Regency. The research used a mixed-methods approach (quantitative and qualitative) through surveys of 30 farmers, in-depth interviews with traditional leaders and stakeholders, and field observations. The results show that the total marketing value from producers was IDR 1,521,000,000 (98 heads), and the end consumers' purchase value was IDR 1,661,000,000, resulting in a marketing margin of IDR 140,000,000. The average marketing efficiency rate was 27.99%, indicating the marketing system is not yet optimal. Kodi culture plays a significant role in determining distribution patterns and price mechanisms, where transactions are still dominated by social relationships and local networks. This study recommends developing shorter marketing channels and integrating cultural values into marketing strategies to improve farmers' economic efficiency.
