Abstract

Abstract— The consumption of kombucha has been increasing in recent years due to its health benefits. However, its strong and distinctive flavor can be a limiting factor for consumer acceptance. Therefore, producing kombucha beads through spherification provides an alternative method of consuming kombucha. This study investigated the effect of sodium alginate (SA) concentration on the release of total phenolic content, reducing sugar, and antioxidant capacity from kombucha beads. Additionally, the stability of kombucha beads in simulated gastric juice was investigated in terms of viable bacteria.  The microstructure of kombucha beads was investigated using a scanning electron microscope (SEM). The result showed that kombucha beads produced tear-shaped beads. Increasing the concentration of sodium alginate led to an increase in the size and hardness of the kombucha beads (P < 0.05). However, increasing the concentration of sodium alginate did not affect the release of total phenolic content, reducing sugar and antioxidant capacity (P ≥ 0.05). Interestingly, 1% SA-kombucha beads had the highest viability of bacteria (P < 0.05) after low pH simulation compared to 2% to 5% SA-kombucha beads. SEM analysis revealed that kombucha beads had cavities and deposits of NaCl at 2% and higher concentrations of sodium alginate. While the FTIR spectra showed that no new peaks were generated in the kombucha beads, stretching peaks were observed at 3000-3500 cm-1. This study highlighted the potential of alginate beads for encapsulating polyphenolic compounds as an innovative approach for food applications. Further study is needed to understand the release behavior of probiotic microorganisms in kombucha during digestion.

Abstract

Kepuasan pelanggan dapat dicapai apabila perusahaan mampu meningkatkan kualitas layanan yang diberikan. Hal ini berpotensi mendorong pelanggan untuk melakukan pembelian secara berulang. Penelitian ini bertujuan untuk menganalisis sejauh mana pengaruh kualitas layanan, fasilitas, dan promosi terhadap kepuasan pelanggan serta dampaknya terhadap niat untuk melakukan pembelian ulang. Penelitian dilakukan dengan pendekatan kuantitatif deskriptif, menggunakan teknik sensus terhadap 100 responden. Hasil penelitian menunjukkan bahwa kualitas layanan, fasilitas, dan promosi berpengaruh secara parsial terhadap kepuasan pelanggan. Selain itu, ketiga variabel tersebut juga memiliki pengaruh tidak langsung terhadap niat pembelian ulang melalui kepuasan pelanggan. Temuan lain menunjukkan bahwa hanya kualitas layanan yang memberikan dampak tidak langsung terhadap niat pembelian ulang melalui kepuasan, sedangkan fasilitas dan promosi tidak memberikan pengaruh signifikan, baik terhadap kepuasan pelanggan maupun niat untuk membeli ulang.

Abstract

This article examines the learning design of Islamic Religious Education (PAI) based on democratic and multicultural values, which can be the answer to the identity crisis experienced by the younger generation in the modern era. In the midst of the influence of globalization, technological development, and increasingly complex cultural and religious diversity, religious education is required to be more than just conveying doctrine. This approach offers learning experiences that encourage active participation, open dialogue, and reflection on students' social reality. Using a qualitative approach, this research was conducted through literature studies and case studies in schools that apply democratic values in Islamic education learning. The results show that this learning model is able to create an inclusive classroom atmosphere, strengthen a sense of empathy, and shape the character of students who are open to differences. The role of the teacher also becomes very important, namely as a value companion and dialogue facilitator, not just a text teacher. Although promising, the implementation of this approach still faces obstacles such as limited teacher understanding, lack of policy support, and lack of contextualized teaching materials. Therefore, cross-stakeholder cooperation is needed to ensure that religious learning is able to form a generation that is religious, tolerant, and ready to coexist in a diverse society.

Abstract

The rapid development of information technology in the digital era demands that teachers integrate technology into the learning process. This challenge not only requires technical skills but also a high level of work motivation. This study aims to describe and analyze the influence of the principal’s transformational leadership in enhancing teacher work motivation at SDN Rancaekek 05 in the digital era. This research employs a qualitative approach using a case study method. Data were collected through in-depth interviews, participatory observations, and document analysis. Informants included the principal, teachers, and other educational staff. The findings reveal that the principal acts as a transformational leader through four key dimensions: setting an example and providing positive influence, delivering an inspiring vision, encouraging innovation in facing digital challenges, and attending to the individual needs and potential of teachers. Strategies implemented include technology training, teacher rewards, and open, participatory communication. This study highlights how transformational leadership can practically foster an adaptive work culture and enhance teachers’ professional motivation amid the challenges of the digital age, particularly in public elementary schools operating with limited resources.

Abstract

Yoghurt merupakan susu fermentasi yang manfaat yang baik untuk tubuh. Adanya penambahan antioksidan seperti senyawa polifenol dari berbagai variasi air seduhan teh dapat memberikan dampak yang lebih baik bagi tubuh.Tujuan penelitian ini adalah untuk mengetahui perubahan karakteristik kimia Caspian Sea Yoghurt yang ditambah dengan air seduhan teh hijau, hitam dan putih. Penelitian ini dilakukan dengan 7 perlakuan terhadap variasi teh yang ditambahkan pada yoghurt yaitu 10% air seduhan teh hijau (10g teh/100ml air), 50% air seduhan teh hijau (5g teh/100ml air), 10% air seduhan teh hitam, 50% air seduhan teh hitam, 10% air seduhan teh putih, 50% air seduhan teh putih dan yoghurt tanpa penambahan teh. Fermentasi dilakukan pada suhu ± 30oC selama 12 jam. Hasil penelitian menunjukkan bahwa penambahan air seduhan teh dan lama waktu fermentasi berpengaruh nyata terhadap kadar asam laktat, nilai pH dan kadar polifenol pada yoghurt teh. Makin banyak penambahan air seduhan teh maka kadar asam laktat dan pH yoghurt akan semakin rendah, namun kadar polifenol akan semakin tinggi. Sedangkan untuk waktu fermentasi, makin lama waktu fermentasi maka pH yoghurt akan semakin rendah sedangkan kadar asam laktat semakin tinggi. Kadar polifenol tertinggi terdapat pada yoghurt dengan penambahan air seduhan teh hijau sedangkan kadar polifenol terendah terdapat pada yogurt dengan penambahan air seduhan teh putih.

Abstract

Usaha Mikro, Kecil, dan Menengah (UMKM) memiliki peran penting dalam perekonomian, namun masih menghadapi tantangan terkait standar keamanan pangan dan legalitas produk. Salah satu upaya peningkatan daya saing adalah melalui penerapan Cara Produksi Pangan Olahan yang Baik (CPPOB) serta pendaftaran izin edar Pangan Industri Rumah Tangga (P-IRT). Program pengabdian kepada masyarakat ini bertujuan meningkatkan pemahaman dan keterampilan UMKM kluster olahan makanan nabati di Kota Bandung melalui pelatihan CPPOB dan pendampingan pendaftaran P-IRT. Metode pelaksanaan meliputi seleksi peserta, pelatihan tatap muka, pendampingan penyusunan manual mutu CPPOB, serta kegiatan gap analysis melalui kunjungan langsung ke tempat produksi. Hasil kegiatan menunjukkan bahwa dari 35 UMKM pendaftar, 5 UMKM lolos seleksi akhir dan mengikuti pelatihan. Peningkatan pengetahuan peserta tercermin dari kenaikan nilai rata-rata post-test (92,8) dibandingkan pre-test (88,75). Evaluasi kuesioner juga menunjukkan tingkat kepuasan tinggi (rata-rata skor 4,7/5) terhadap kualitas materi, metode penyampaian, dan interaktivitas pelatihan. Selain itu, seluruh UMKM peserta berhasil menyusun dokumen manual mutu CPPOB sebagai prasyarat pengajuan izin edar, serta memperoleh catatan perbaikan melalui gap analysis untuk meningkatkan standar keamanan pangan. Pelatihan CPPOB dan pendampingan P-IRT mampu meningkatkan kapasitas UMKM dalam penerapan keamanan pangan dan memperkuat daya saing produk. Disarankan agar program serupa diperluas dengan cakupan peserta lebih banyak serta dilakukan pendampingan lanjutan hingga tahap implementasi penuh CPPOB dan sertifikasi izin edar.
