Beef is one of the most important sources of animal protein with high nutritional value. This study aimed to identify the presence of Salmonella bacteria in beef sold at Pasar Tavip Binjai and Pasar Kebun Lada, Binjai City. The research was conducted using laboratory testing methods at the Medan Veterinary Center Laboratory during October–November 2025. A total of 13 beef samples were collected through random sampling, consisting of 10 samples from Pasar Tavip Binjai and 3 samples from Pasar Kebun Lada. Each 100-gram sample was placed in a sterile plastic bag, transported using a coolbox with ice packs, and analyzed through pre-enrichment in 225 ml Lactose Broth (LB) for 24 hours at 37°C, enrichment with Tetrathionate Broth (TTB) and Rappaport Vassiliadis Broth (RV), isolation on Hektoen Enteric Agar (HE), Xylose Lysine Deoxycholate Agar (XLD), and Bismuth Sulfite Agar (BSA), and biochemical confirmation using Triple Sugar Iron Agar (TSIA), Urease, and Lysine Decarboxylase Broth (LDB) in accordance with the National Standardization Agency standards (2008). The test results showed that all samples were negative for Salmonella (100%). No specific Salmonella colonies were found on the selective media, and no positive reactions occurred in the biochemical tests. These results indicated that the beef in both traditional markets was free from Salmonella contamination during the sampling period.

Beef is a highly nutritious food source and is essential for fulfilling human nutritional needs. Good-quality meat can be obtained in traditional markets with hygienic conditions and minimal microbial contamination. Inadequate sanitation can trigger various diseases; therefore, proper sanitation practices in traditional markets are crucial as preventive and monitoring measures to prevent the spread of infectious diseases in the community. Serdang Bedagai Regency is one of the regencies in North Sumatra whose main source of animal protein comes from beef. There are several traditional markets in this regency, such as Sei Rampah Public Market, Bedagai Market, and Bengkel Market. These three locations are the centers of beef sales in Serdang Bedagai Regency. This study aims to analyze microbial contamination in beef sold in several traditional markets in Serdang Bedagai Regency. The study used a descriptive method to determine bacterial contamination in beef. Research parameters included observation of Total Plate Count (TPC) and microbial contamination analysis, including E. coli, Staphylococcus aureus, and Salmonella spp. contamination. The results showed the highest TPC at SR3 with 2 × 10⁷ CFU/g, the highest E. coli contamination at TB2 with 78 × 10³ CFU/g, the highest Staphylococcus aureus contamination at SR3 with 378 × 10² CFU/g, and only the SR3 sample was positive for Salmonella spp. contamination. Based on the Indonesian National Standard (SNI) No. 7388-2009 on the maximum limit of microbial contamination in food, the test results for TPC, E. coli, and Staphylococcus aureus contamination exceeded the threshold, and one sample was found to contain Salmonella spp.

This study was conducted in Rambung Susu Village, Simalungun Regency, North Sumatra, at the end of 2025, aiming to analyze the feasibility and income of beef cattle farming. The research method used was a descriptive quantitative approach, with data collected through observation and interviews using questionnaires. The sample was determined using purposive sampling with criteria including farmers having at least 3 years of experience, owning ≥5 cattle, and implementing an intensive management system. The data used consisted of primary and secondary data. The analysis was carried out by calculating total cost (TC), total revenue (TR), net income, and the business feasibility ratio (R/C). The results showed that the average total production cost was IDR 62,015,416.67, while the total revenue was IDR 78,566,666.67, resulting in a net income of IDR 16,551,250. The R/C Ratio value of 1.27 indicates that beef cattle farming is feasible and profitable, where every IDR 1 of cost generates IDR 1.27 in revenue. Thus, beef cattle farming in the study area has good economic prospects and strong potential for sustainable development to improve farmers’ welfare.
