The Effect Of Hydrogen Peroxide (H₂O₂) in Yoghurt (Lactobacillus bulgaricus and Streptococcus thermophilus) on Inhibiting the Growth of Streptococcus pyogenes
No full textYoghurt is a food product made from milk fermented with lactic acid bacteria (LAB), which provides various health benefits, including enhancing immunity through the production of lactic acid, hydrogen peroxide, diacetyl, and bacteriocins. Several studies have reported that LAB-fermented yoghurt can inhibit the growth of pathogenic bacteria. Streptococcus pyogenes is a gram-positive bacterium that forms chain like colonies, is small, round in shape, has a smooth surface, and produces grayish-white pigmentation on blood agar. S. pyogenes can cause respiratory infections such as pharyngitis, and skin infections such as impetigo, cellulitis, and erysipelas. This study aimed to investigate the role of hydrogen peroxide in yoghurt (L. bulgaricus and S. thermophilus) in inhibiting the growth of S. pyogenes. This was an experimental study using a post-test-only control group design. Bacterial colony counts were performed using a colony counter. A total of 60 samples were used, with three repetitions, two dilutions, and ten concentration groups (0%, 5%, 10%, 15%, 20%, 25%, 30%, 35%, 40%, 45%), with 0% serving as the control. Data were analyzed using the Kruskal-Wallis test, followed by the Spearman Rho test. The results showed that yoghurt inhibited the growth of S. pyogenes, and the 30% yoghurt concentration, containing 0.32 mmol/L hydrogen peroxide, was the minimum inhibitory concentration. Kruskal-Wallis analysis showed significant differences among groups (p<0.05), and the Spearman Rho test indicated a significant correlation (p<0.05) between the variables

In Vitro Antifungal Activity Test of Garlic Extract (Allium sativum L.) Againts Aspergillus niger
No full textBackground: Aspergillosis that caused by Aspergillus niger is one of the leading causes of death in Aspergillosis cases, with the highest mortality rate. Resistance of A. niger to various antifungal drugs continues to increase each year. Garlic (Allium sativum L.) is a potential alternative antifungal therapy due to its bioactive compounds such as allicin, saponin, flavonoid, and tanin. Objective: To determine the antifungal activity of garlic (Allium sativum L.) extract at concentrations of 40%, 60%, 80%, and 100% against A. niger isolates in vitro. Methods: This study used a true experimental posttest-only control group design. The antifungal activity was assessed using the well diffusion method with garlic extract concentrations of 40%, 60%, 80%, and 100%, along with positive, negative, and 10% DMSO controls. Data were analyzed using the Kruskal-Wallis test due to the non-normal and non-homogeneous distribution, followed by the Games-Howell post hoc test. Results: The garlic extract produced inhibition zones that were considerably smaller than those in the positive control group. For this research, wells with a diameter of 6 mm were used. The inhibition zones for 40%, 60%, 80%, and 100% concentrations were 7.25 mm, 6.5 mm, 6 mm, and 6.75 mm, respectively. The positive control (itraconazole 8 µg/mL) produced an inhibition zone of 17 mm. Conclusion: Garlic extract did not exhibit significant antifungal activity against A. niger, as indicated by the minimal inhibition zones compared to the positive control

T Transformasi Sistem Ekonomi Terpusat di Vietnam: Pelajaran bagi Reformasi Ekonomi Indonesia
No full textTransformasi sistem ekonomi Vietnam sejak penerapan kebijakan Đổi Mới tahun 1986 menjadi rujukan penting bagi negara-negara berkembang dalam membangun perekonomian yang tangguh dan adaptif. Penelitian ini bertujuan untuk mengeksplorasi keberhasilan strategi reformasi ekonomi Vietnam dan mengevaluasi relevansinya terhadap upaya reformasi ekonomi Indonesia pascakrisis 1998. Pendekatan kualitatif deskriptif digunakan melalui metode studi kasus komparatif, dengan dukungan analisis kebijakan publik dan kerangka reformasi struktural dari OECD. Hasil penelitian menunjukkan bahwa keberhasilan Vietnam tidak hanya disebabkan oleh liberalisasi sektor ekonomi, tetapi juga oleh konsistensi arah kebijakan, penguatan institusi publik, serta pengelolaan makroekonomi yang stabil. Sebaliknya, Indonesia masih menghadapi hambatan struktural akibat reformasi yang kurang terkoordinasi dan lemahnya kapasitas kelembagaan. Dengan demikian, pengalaman Vietnam memberikan pelajaran penting bahwa reformasi ekonomi yang efektif membutuhkan visi jangka panjang, sinergi antarsektor, dan perbaikan tata kelola secara berkelanjutan untuk mewujudkan pertumbuhan yang inklusif dan resilien
