Abstract

Response Surface Methodology (RSM) has been widely employed for optimizing processes. However, the implementation of RSM in sensory studies is still limited. Moreover, most publications implementing RSM on sensory disregarded the validation stage as normally applied for process optimization. In this study, validating sensory overall acceptability with RSM was proposed by the Just-About-Right (JAR) technique. Coffee-leaf tea has great commercial potential as an ethnic beverage with unique sensory attributes but is still underutilized. Optimizing sensory acceptability level by modifying temperature and duration of brewing using the RSM was expected to obtain well-accepted coffee-leaf tea.  Robusta coffee leaf tea is brewed using combined Decoction - V60, French Press, combined French Press - V60, and V60 at 90oC to 100oC for 2 to 10 minutes. Evaluated by 110 untrained panelists, it was observed that the ideal brewing parameters for each technique were 96.6oC for 6.5 minutes for Decoction – V60, 96oC and 6.5 minutes for French Press, 90oC and 2 minutes for French Press - V60, and 90oC and 2 minutes for V60. All optimum brewing conditions based on RSM were successfully validated by overall acceptability on JAR (p-value 0.05). Thus, the JAR technique can enhance the overall sensory acceptability analysis and optimization.

Abstract

This study aims to analyze the role and urgency of utilizing media and technology in Islamic Religious Education (PAI) learning as an effort to enhance the effectiveness, relevance, and attractiveness of the learning process in the digital era. The use of media and technology is viewed as a strategic step to integrate Islamic values with contemporary developments and the needs of modern learners. The research method employed is a Systematic Literature Review (SLR) by examining various sources such as books, scientific journals, and research findings related to the application of media and technology in PAI learning. The results indicate that media and technology play an important role in helping teachers deliver PAI materials in a contextual, interactive, and inspiring manner. The utilization of digital technologies, such as instructional videos, online platforms, Islamic applications, and educational social media, can increase students’ motivation, creativity, and engagement in understanding Islamic values. Nevertheless, challenges such as the digital divide, the validity of religious information, and the risk of declining spiritual interaction must also be anticipated. The implications of this study emphasize that PAI teachers need to act as wise and adaptive digital murabbi without losing the essence of Islamic spirituality. Schools are expected to provide support in the form of training, facilities, and a conducive learning environment so that media and technology truly function as tools for da‘wah, character building, and strengthening Islamic values in the modern era.

Abstract

Abad ke-21 menandai perubahan besar dalam paradigma pendidikan yang menuntut transformasi cara belajar dan mengajar. Perkembangan teknologi digital, globalisasi, serta perubahan karakteristik peserta didik mengharuskan guru beradaptasi dengan strategi pembelajaran yang lebih inovatif, kolaboratif, dan berorientasi pada kompetensi. Artikel ini membahas dinamika perubahan paradigma pendidikan abad ke-21, tantangan utama yang dihadapi dalam penerapan pembelajaran inovatif, serta arah dan strategi transformasi yang dapat dilakukan oleh pendidik masa depan. Metode kajian yang digunakan adalah deskriptif-analitis dengan meninjau berbagai literatur dan kondisi lapangan. Hasil kajian menunjukkan bahwa meskipun teknologi telah membuka peluang besar bagi modernisasi pendidikan, banyak guru masih kesulitan mengintegrasikan pendekatan berbasis proyek, literasi digital, dan pembelajaran reflektif. Diperlukan transformasi paradigma yang menempatkan peserta didik sebagai subjek aktif, penguatan kompetensi pedagogik guru, serta dukungan sistemik sekolah dalam menciptakan lingkungan belajar adaptif, inovatif, dan berkelanjutan sesuai tuntutan abad ke-21.
