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 study aims to analyze the effect of using cassava (Manihot esculenta crantz) as a carbohydrate-based feed ingredient on body weight gain in beef cattle. The review was conducted using a descriptive literature study approach based on sixteen scientific articles discussing the nutritional composition, processing methods, and performance responses of beef cattle fed cassava-based diets. The analysis shows that cassava contains 17.45–88.6% dry matter, 2.4–21.45% crude protein, and 11.35–92.2% nitrogen-free extract, with variations influenced by plant part, processing method, and hydrocyanic acid (HCN) content. Processing techniques such as fermentation and ensiling can reduce HCN levels by more than 70% while increasing crude protein content up to 25%, thereby improving digestibility and feed efficiency. The inclusion of cassava in the form of flour, dried chips, pulp, or fermented peel consistently enhances dry matter intake and average daily gain (ADG) of beef cattle at inclusion levels of 20–50% in the diet. Overall, cassava has strong potential as a locally available, economical, and sustainable feed ingredient to improve beef cattle productivity.

This study aims to improve the effectiveness of facility arrangement at Pabrik Oncom Bu Nana by analyzing interactions among production activities and designing spatial layouts based on their priority levels. The current layout presents several critical issues, particularly because the equipment sanitation area is combined with the toilet, creating a significant risk of contamination and reducing hygiene during production. In addition, irregular material flow and excessive worker movement lead to inefficient work processes and may affect the quality of the final product. To address these issues, this study employs the Activity Relationship Chart (ARC) to evaluate the functional closeness among production areas, as well as the Total Closeness Rating (TCR) to determine facility placement priorities based on the intensity of inter-stage relationships. The results of the ARC analysis indicate that the fermentation room has the strongest link to the main stages of oncom production, requiring its placement to be closer to the preparation and molding areas. Findings from the TCR further emphasize that fermentation should become the primary focus in the layout redesign. Based on both methods, a more organized layout design is proposed by relocating the fermentation room to the beginning of the production flow, separating the toilet and sanitation room into two distinct areas, and restructuring the storage, molding, and drying spaces. This redesigned layout is expected to enhance cleanliness, improve material flow, and strengthen the operational effectiveness of Pabrik Oncom Bu Nana.

This study aims to analyze the effect of nutrient types on kombucha fermentation using Sosro Tea as a medium. The practicum was conducted with two variations, namely honey as a natural nutrient and Tropicana Slim as a low-calorie sweetener. Parameters observed included color changes, aroma, SCOBY layer formation, pH, and microbial contamination. The results showed that fermentation using honey produced the best combination, which was characterized by a brighter color change, a stable sour aroma, the formation of a thick and pure white SCOBY, and a stable pH of around 4. In contrast, fermentation using Tropicana Slim failed to achieve optimal results. This low-calorie sweetener cannot be metabolized by microbes, resulting in a thin SCOBY and the appearance of green-black mold. Based on these results, it can be concluded that the success of kombucha fermentation is greatly influenced by the availability of simple sugars, which are the main energy source for the SCOBY. In addition, the culture's resistance to microbial contamination also plays an important role in the fermentation process.
