Abstract

Background: One of the main challenges in yoghurt production is the potential for microbiological contamination, especially by Coliform bacteria. Meanwhile, red grapes (Vitis vinifera L.) are known to have bioactive content that has the potential to improve yoghurt quality by not only suppressing coliform bacteria, but also increasing Lactic Acid Bacteria (LAB), reducing pH and acid levels, and improving sensory preferences. Objectives: This study aims to investigate the microbiological, chemical, and organoleptic characteristics of yoghurt after the addition of red grape juice (Vitis vinifera L.). Methods: This study is an exploratory study conducted with four concentrations: K0 (without the addition of red grape juice), K1 (5%), K2 (10%), and K3 (15%). The parameters observed include the number of Coliform bacteria, LAB, lactic acid levels, pH, and organoleptic tests. Data analysis of the total number of LAB, lactic acid levels, the number of coliform bacteria and pH values ​​was carried out descriptively quantitatively. Meanwhile, the results of the organoleptic test were compared between groups using the Kruskal-Walli’s test statistics. Results: The results showed that K3 produced the highest total BAL of 2.71 × 10⁹ CFU/mL. The lowest number of Coliforms of 3 apm/mL was produced by K2, in accordance with the yoghurt quality standards based on SNI 2981:2009. The highest lactic acid content was recorded in K3 of 1.89%, while the lowest pH value was achieved in K3 with a value of 4.00. Organoleptic tests showed that K2 and K3 gave the highest average values ​​for taste, aroma, and color attributes, with a tendency for consumer preference to increase along with the addition of fruit juice concentration. Conclusion: The most favorable results were obtained at concentrations of 10% (K2) and 15% (K3), which provided an optimal balance between sensory quality, microbiological safety, and chemical stability of the product. The addition of red grape juice increased the functional value of yoghurt in microbiological, chemical, and organoleptic aspects.

Abstract

Reactive Black 5 (RB5) is an azo dye widely used in the textile industry and improper processing of this dye can harmful to the aquatic environment, including limited light penetration and potential carcinogenic and mutagenic effects on aquatic organisms. Therefore, RB5 in waters needs to be handled seriously, one of which is through bioremediation efforts using Cholera vulgaris. Meanwhile, chlorella growth is highly dependent on various light spectrums. This study aimed to examine the effect of different light spectrums (red, blue, and white) on C. vulgaris cell density-based growth and its ability to decolorate RB5. A completely randomized design with three replications was applied using 30 mg/L RB5 solution, and was conducted for 12 days at laboratoty. Cell density was measured by a hemocytometer, and dye concentration was analyzed using a UV-Vis spectrophotometer. The results showed that blue light produced the highest algal growth, reaching 2.78 × 10⁷ cells/mL on the ninth day. Meanwhile, white light produced the greatest RB5 decolorization, reaching 80% reduction on the last day. These findings highlight the role of different light spectrums in optimizing algal cell density and dye removal efficiency.

Abstract

The COVID-19 pandemic has impacted the closure of almost all learning processes in Islamic boarding schools. Only some Islamic boarding schools have succeeded in modifying learning methods, one of which is the Darul Faqih Indonesian Islamic Boarding School located in Malang Regency, Indonesia. This community service aims to support efforts to strengthen the digitalisation of Darul Faqih Indonesian Islamic boarding school and direct the development of hybrid Islamic boarding schools after the Covid-19 pandemic. This community service activity consists of two phases. First, at the beginning of the semester, teachers are given training to strengthen the use of learning management systems and mobile apps. In the second phase, the teacher was invited back to conduct a focus group discussion at the end of the implementation. At the end of this service activity, impact measurements were also carried out from a teacher's perspective. A total of 58 teachers participated in this activity. Less than half of teachers have a preference for mixed learning. However, they have high self-efficacy in implementing effective learning to support the implementation of hybrid pesantren. Constraints during mixed learning are appropriate technological and pedagogical support. Despite some challenges, teachers have so far been able to adapt to various online learning methods. Most agree that blended learning can be next as the next main effort towards hybrid pesantren.[Pandemi Covid-19 berdampak pada penutupan hampir semua proses pembelajaran di pondok pesantren. Hanya sebagian pondok pesantren yang berhasil memodifikasi metode pembelajaran, salah satunya adalah Pondok Pesantren Darul Faqih Indonesia yang berlokasi di Kabupaten Malang, Indonesia. Pengabdian masyarakat ini bertujuan untuk memberikan dukungan dalam upaya penguatan digitalisasi pesantren Darul Faqih Indonesia dan mengarahkan pada pembangunan pesantren hibrid pasca pandemi Covid-19. Kegiatan pengabdian masyarakat ini terdiri dari dua fase. Pertama, pada awal semester, guru diberikan pelatihan untuk penguatan penggunaan learning manajemen system dan mobile app. Fase kedua, di akhir penerapan, guru diundang kembali untuk melakukan Focus Group Discussion. Di akhir kegiatan pengabdian ini juga dilakukan pengukuran dampak berupa perspektif guru. Sebanyak 58 guru berpartisipasi dalam kegiatan ini. Kurang dari separuh guru yang memiliki preferensi terhadap pembelajaran campuran. Namun, mereka memiliki efikasi diri yang tinggi dalam melaksanakan pembelajaran yang efektif untuk mendukung implementasi pesantren hibrid. Kendala selama pembelajaran campuran adalah dukungan teknologi dan pedagogi yang tepat dan sesuai. Meskipun ada beberapa tantangan, guru sejauh ini mampu beradaptasi dengan berbagai metode pembelajaran daring, dan mayoritas setuju bahwa pembelajaran campuran dapat diterapkan selanjutnya sebagai upaya utama menuju pesantren hibrid.]
