The normal flora of chickens refers to the microbial communities that naturally inhabit the gastrointestinal tract and body surfaces of chickens, playing a crucial role in health, digestion, and immunity. This community consists of beneficial bacteria such as Lactobacillus, Bifidobacterium, and Bacillus, which assist in feed fermentation, vitamin synthesis, and inhibition of pathogenic growth. Additionally, the normal flora may include potential pathogenic bacteria such as Escherichia coli, Salmonella spp., and Campylobacter, which can cause diseases if microbial balance is disrupted. The diversity and balance of the microbiota are influenced by various abiotic factors, including feed quality, access to clean water, ambient temperature, humidity, and environmental hygiene. Biotic factors, such as microbial interactions, rearing systems, and contact with other animals, also play a significant role in determining microbial composition. Several studies have shown that the use of feed additives, such as probiotics and phytogenics, can enhance populations of beneficial bacteria while suppressing pathogenic bacteria. Extensive rearing systems, which provide chickens with more space and exposure to natural environments, tend to increase microbiota diversity compared to semi-intensive systems with more restricted conditions. Understanding these factors is essential for developing effective health management strategies and optimizing safe and sustainable poultry production.

This paper examines how The Picture Dorian Gray by Oscar Wilde marks a critical turn in which he critiques late-Victorian upper-class privilege and moral immunity. While previous scholarship has predominantly analyzed the novel as a moral allegory or aesthetic treatise, this study employs cultural materialism as a theoretical framework to demonstrate how Wilde uses Dorian’s isolation of his portrait and subsequent hedonistic experimentation as symbolic representations of the aristocracy’s ability to shield him from moral and social consequences. Wilde’s text reveals how the English aristocracy could embody ideals of beauty and reap princely treatment while committing debauchery without reproach. Through Culler’s close reading method toward this novel, especially chapters eight and nine, this analysis reveals how Dorian’s act of hiding the portrait symbolizes social denial, while his obsessive aesthetic consumption reflects the practices of the leisure class. This shows that Wilde hints Dorian’s social circle accepts his sensual life simply because his appearance remains unmarred–a commentary on class privilege. By examining the specific textual elements and historical context of—especially—chapters eight and nine of this novel, this study contributes to the understanding of how Wilde’s novel serves as both a product of and commentary on the class structures and moral hypocrisy of late-Victorian England.

COVID-19 is caused by the SARS-CoV-2 virus which infects the respiratory system and transmitted by droplets. This study aims to see the effect of administering Nigella sativa which has an immunomodulatory effect in reducing the clinical manifestations of COVID-19 disease by increasing the immune system. The method used is a literature review of five selected journals through a prism diagram flow from the PubMed, SpringerLink, and ScienceDirect electronic databases. Clinical manifestations of COVID-19 in patients decreased the length of patients’ hospital stay which become shorter in the intervention group compared to the control group. Nigella sativa has a positive response to increasing immunity. The immunomodulatory effect of NS is proven in increasing macrophage phagocytosis, immunoglobulin titer, lymphocyte ratio, and preventing T cell depletion and encouraging specific T cell proliferation.

This community service program aims to develop nutraceutical-based health products from temu mangga (Curcuma mangga Val.van Zip) and probiotics, called "TEMAPRO". Research and socialization were conducted in Pulau Semambu Village, South Sumatra, targeting village mothers who have limited knowledge about the benefits of herbs and probiotics. Temu mangga, which is traditionally consumed as a salad and herbal medicine, contains various active compounds that have the potential as antioxidants and anti-cancer. Combined with the probiotic Lactobacillus rhamnosus, this product is expected to support digestive health and increase body immunity. Implementation methods include education, training in making temu mangga extract, mixing with probiotics, and product packaging techniques. The results of the activities showed an increase in community understanding and skills in processing local materials into health products with economic value. It is hoped that "TEMAPRO" will not only improve the quality of public health, but also open up business opportunities in the village through local nutraceutical products.
