Abstract

This study examined the prevalence of Escherichia coli bacteria producing Extended-Spectrum Beta-Lactamase (ESBL) and modeled the ingestion rate in closed-house farms in Sukabumi. The results of the Monte Carlo simulation showed a range of daily fecal exposure (EED) between 0.0016 and 0.2417 grams per day, reflecting variations in worker activity, contact type, and cleanliness of the farm environment. Factors such as ingestion rate, the weight of stool adhering to gloves, and the frequency of hand-to-mouth contact affect exposure to pathogenic microbes, with higher ingestion rates associated with increased risk. Exposure is influenced by the type of activity, duration of contact, and level of hygiene; activities such as feeding and cleaning cages have the potential to cause high contamination. Monte Carlo-based probabilistic models and bootstrapping effectively describe the distribution of exposure and account for the uncertainty in the data, providing a basis for health risk mitigation policies related to exposure to resistant E. coli. These findings are important for the development of antimicrobial resistance control policies in the livestock sector, particularly for improving biosecurity measures to reduce AMR exposure in livestock workers.

Abstract

Penggunaan kebutuhan kalor yang sangat besar pada industri. Untuk mengatasi kebutuhan kalor yang besar ini maka perlu dilakukan usaha untuk meningkatkan efisiensi pada kalor tersebut . Cara yang paling efektif untuk mengurangi permintaan adalah dengan menggunakan energi lebih efektif. Salah satu cara pengaplikasiannya yaitu penukar panas. Alat penukar panas (heat exchanger) adalah perangkat yang menyediakan aliran energi termal anatra dua atau lebih cairan pada suhu yang berbeda. Dalam proses perpindahan panas di setiap heat exchanger melibatkan dua fluida tube Tujuan dari penelitian ini untuk mendapatkan data konsentrasi fluida etilen glikol - polyethylen glikol terhadap nilai U pada alat heat exchanger shell and tube 1-1 mengunakan fluida sistem polyethylen glikol- ethylen glikol dengan aliran co-current. Variable yang digunakan dalam penelitian ini adalah suhu fluida panas masuk berkisr 40,45,50,55,60 0C, suhu fluida dingin masuk 15,20,25,30 0C, Nilai koefisien perpindahan panas overall paling besar diperoleh pada temperatur fluida masuk 50°C yaitu sebesar 135,4576 W/m2°C pada aliran co-current.

Abstract

Antimicrobial resistance (AMR), particularly Extended-Spectrum Beta-Lactamase–producing Escherichia coli (ESBL-Ec), poses a global threat to human, animal, and environmental health. Intensive broiler farms serve as important reservoirs of ESBL-E.coli, exposing workers through ingestion during routine activities. This study aimed to assess ESBL-Ec prevalence and estimate ingestion exposure among workers in closed-house broiler farms in Sukabumi City. Laboratory and field analyses were conducted using spread plate methods, MCA-CTX selective media, and ESBL confirmation by Double Disk Synergy Test (DDST) on samples from workers’ Footwear. The concentration of E. coli bacteria on the surface of the sandals in the dry season was (1.37 ± 0.02) × 103 CFU/cm2), while in the rainy season it was (1.16 ± 0.05) × 10³ The confirmed concentration of ESBL-Ec bacterial colonies was (0.42 ± 0.02) × 10³ CFU/cm²). Meanwhile, for the rainy season, the ESBL-Ec concentration obtained was (0.14 ± 0.03) × 10³ CFU/cm².The results of this study confirm that workers' footwear in closed-house broiler farms is a real reservoir for the spread of ESBL-E.c bacteria. The high concentrations of bacteria found, both in the dry and rainy seasons, indicate the need for stricter biosecurity protocols and routine sanitation of work equipment to mitigate the risk of transmitting antimicrobial resistance from the farm environment to humans.
