Abstract

Diabetes Mellitus is a chronic condition characterized by fasting blood glucose levels of less than 126 mg/dl, which are above the normal range. DM is otherwise called the quiet executioner since it is frequently not understood and when it is found complexities have happened. Monounsaturated fatty acids (MUFA), which have anti-diabetic properties, can be found in olive oil, a functional food. Fig leaves contain flavonoid compounds, β-setosterol, and these polyphenols are accounted for to work as antidiabetics. The point of this study was to decide the impact of directing olive oil and fig leaf separate on fasting blood glucose levels in white rodents. This study employs a Pretest-Posttest Control Group Design and quantitative experimental research methods. The examples utilized were 24 mice. The independent t-test was used to process the results, and One Way Annova was used to carry on. According to the findings of the study, the group that received olive oil had a fasting blood glucose of 41.00 mg/dL (p0.004), the group that received fig leaf extract had a p value of 37.25 mg/dL (p0.005), and the group that received a mixture of olive oil and fig leaf extract had a p value of 39.00 mg/dL (p0.004). Olive oil and fig leaf extract both have an effect on the blood glucose levels of mice induced by Aloxan, but the combination yields more significant results. This is the study's conclusion.

Abstract

Death due to infection is the most common cause and is a challenge in the health sector. In 2019, 7.7 deaths were due to bacterial infections, 90 to 100 cases were urinary tract infections and Escherichia coli bacteria contributed to 90% of urinary tract infections. This research uses the Kirby Bauer Disc method to determine the effectiveness of Saliara (Lantana camara) leaves against Escherichia coli bacteria. The type of research is a Laboratory experiment using the Kirby Bauer disc method with a post-test-only control group design. Data analysis uses recording of identifying the inhibition zones formed The research showed that a sample's concentration can influence the inhibition zone's resulting diameter. Saliara leaf extract with concentrations of 100%, 150%, and 200% produced an inhibition zone of 8.55 mm; 9.59mm; 12.34 mm in the proliferation of Escherichia coli bacteria. The positive control with the antibiotic ciprofloxacin produced an inhibition zone of 19.56 mm on the growth of Escherichia coli bacteria. Control with negative distilled water does not create an inhibition zone because it does not have antibacterial activity. The conclusion is moderate inhibitory activity in Saliara (Lantana camara L.) leaf extract at concentrations of 100% and 150%. It is strong at a concentration of 200% against the growth of Escherichia coli bacteria.

Abstract

Inflammatory Bowel Disease (IBD) is a chronic intestinal disorder consisting of Crohn’s Disease (CD) and Ulcerative Colitis (UC). The highest prevalence of IBD is found in Asia and the cases often occur in the 15-35 group of age. Conventional therapy options that are commonly used have some side effects that impact IBD patients. Therefore, it is necessary to look for new strategies in order to treat IBD regarding their effectiveness, affordability and achieving minimum side effects. Resveratrol, a natural non-flavonoid polyphenolic compound, is commonly found in grapes and various types of berries. It is known to potentially overcome inflammation in IBD through various mechanisms including acting as anti-inflammatory, antioxidant, immunomodulatory effects, and its ability to influence the gut microbiota. This study is aiming for explaining and reviewing further mainly on resveratrol’s extraction method and its mechanism of actions to improve IBD. The resources for this study are done by searching through PubMed, ProQuest, ScienceDirect, MDPI, and Google Scholar with keywords (Inflammatory Bowel Disease) AND (Resveratrol), ⁠(Incidence and Prevalence) of Inflammatory Bowel Disease across Asia, (Threat) AND (Therapy) AND (Inflammatory Bowel Disease), (Bioactive) AND (Therapy) AND (Inflammatory Bowel Disease), (Extraction) AND (Method) AND (Resveratrol), and (Pathophysiology) AND (Inflammatory Bowel Disease). Based on evidence found on resveratrol’s benefits, this compound is apparently promising to alternatively treat IBD, but still needs more research to support its effectiveness.

Abstract

Busy activities make people prefer to consume ready-to-eat food which sometimes does not guarantee the level of cleanliness, so that cases of food poisoning often occur. Bacillus cereus is a bacteria that causes food poisoning which is usually found in rice. To overcome this problem, research was carried out to find new sources of medicine from endophytic fungi, namely fungi that live in plant tissue. The addition of clinical drugs derived from fungi has attracted interest in the discovery of new secondary metabolites derived from endophytic fungi. This research aims to (1) obtain endophytic fungal isolates isolated from red ginger rhizomes, (2) obtain endophytic fungal isolates that are antibacterial against Bacillus cereus. The method used is a laboratory experiment by randomizing and repeating the samples. The results showed that four isolates of endophytic fungi were successfully isolated from red ginger rhizomes with varying inhibitory abilities between isolates. The highest percentage of inhibitory power based on the in vitro dual culture assay was a cream colored isolate of 100 ± 0.0%.

Abstract

The study examines the effects of supplementing coffee grounds to commercial feed on the growth, feed utilization and survival rates of Nile tilapia (Oreochromis niloticus). Given that feed quality and environmental conditions significantly impact fish productivity, the inclusion of coffee grounds, rich in antioxidants and potential immunostimulants, was hypothesized to enhance fish growth and health. The experiment, conducted over 45 days, involved five treatments with varying coffee ground concentrations (0%, 2%, 4%, 6%, and 8%) within a Completely Randomized Design (CRD). Each treatment was replicated three times, resulting in a total of 15 experimental units. Results indicated significant improvements in growth parameters, including absolute weight and length, relative growth, and specific growth rates, particularly at the 6% concentration. However, feed conversion ratio (FCR) and feed utilization efficiency (EPP) did not show significant differences. The study concludes that a 6% coffee ground concentration is optimal for promoting tilapia growth without adversely affecting feed efficiency.

Abstract

Hospital activities generate by-products from the treatment of liquid waste, namely sludge that settles in sedimentation tanks. The sludge produced thus far has been transported by a third party in collaboration with the hospital. This study was conducted to utilize hospital wastewater treatment plant (WWTP) sludge with the aim of determining the moisture content, carbon (C) content, nitrogen (N) content, and C/N ratio in the raw WWTP sludge before and after composting compared to SNI 19-7030-2004 standards. Additionally, the study aimed to identify the average differences in each variation of WWTP sludge and rice husk composition. This research employed an experimental method. The composting process was conducted aerobically with the following variations: 95% WWTP sludge:5% rice husk (A1), 85% WWTP sludge:15% rice husk (A2), 75% WWTP sludge:25% rice husk (A3), and 65% WWTP sludge:35% rice husk (A4), with the addition of EM4 activator 55 ml + 90 ml sugar solution diluted to 300 ml. The preliminary test results for the WWTP sludge showed a moisture content of 68.76%, C content of 28.00%, N content of 14.32%, and C/N ratio of 1.95. From the results of the ANOVA statistical test and Post Hoc Duncan test, it was found that the average variation in WWTP sludge: rice husk composition had a significant difference, with the ideal composition being variation A1 (95% WWTP sludge:5% rice husk).
