Abstract

Sapi perah merupakan hewan ruminansia yang menghasilkan susu untuk konsumsi sehari hari masyarakat Indonesia karena mengandung sumber kalsium yang baik bagi tubuh. Namun, saat ini kendala yang dihadapi oleh peternak adalah menurunnya produksi susu sapi perah sehingga menyebabkan kerugian ekonomi yang cukup besar. Salah satu penyakit yang menyebabkan penurunan produksi susu pada sapi perah adalah Bovine Viral Diarrhea (BVD). Bovine Viral Diarrhea telah menyebar di seluruh dunia termasuk di Indonesia. Pemerintah Indonesia belum menetapkan kebijakan vaksinasi BVD. Tujuan penelitian ini adalah untuk mengetahui seroprevalensi dan faktor resiko mengenai infeksi Bovine Viral Diarrhea (BVD) di tingkat peternak di Kabupaten Sleman Yogyakarta. Metode penelitian ini adalah dengan melakukan wawancara terhadap peternak melalui kuesioner dan metode sampling yang digunakan pada penelitian ini adalah teknik sampling tahapan ganda serta dianalisis secara univariat dan bivariat. Sampel penelitian ini adalah 96 peternak terpilih yang memiliki sapi perah dan dilakukan pengujian Bovine Viral Diarrhea (BVD) dengan metode Enzyme-linked Immunosorbent Assay (ELISA) antibodi. Berdasarkan analisis univariat, diperoleh seroprevalensi penyakit BVD pada sapi perah sebesar 56,25%. Berdasarkan analisis bivariate, hasil yang diperoleh adalah tidak terdapat hubungan antara variabel yang diuji dengan adanya penyakit BVD pada sapi perah di Kabupaten Sleman, yang ditunjukkan dengan nilai p_value > 0.05.

Abstract

Java, situated in the Pacific Ring of Fire, is one of the most seismically active regions in the world, with frequent earthquakes posing significant risks to its dense population and critical infrastructure. This study aimed to analyze the spatial distribution and intensity patterns of earthquakes in Java from 2022 to 2024 using data from the Meteorology, Climatology, and Geophysics Agency (Badan Meteorologi, Klimatologi, dan Geofisika, BMKG). Spatial interpolation techniques—inverse distance weighted (IDW), nearest neighbor, and Thiessen polygon—were applied to evaluate their effectiveness in mapping earthquake intensity patterns. The dataset included the earthquake magnitude, location, and occurrence time, with performance evaluated using mean absolute percentage error (MAPE) and mean absolute error (MAE). Results showed that the nearest neighbor method achieved the highest accuracy (MAPE of 12.27%, MAE of 0.37), followed by IDW, while the Thiessen polygon method demonstrated limited suitability for continuous seismic phenomena. These findings underscore the importance of selecting appropriate interpolation methods for seismic risk mapping, providing actionable insights for disaster preparedness and urban planning in Java.

Abstract

Lumpy Skin Disease (LSD) is an infectious dermatological condition affecting ruminant animals, particularly cattle, and is caused by the Lumpy Skin Disease Virus (LSDV). This virus possesses DNA genetic material derived from the Capripoxvirus genus within the Poxviridae family. The World Organization for Animal Health (WOAH) states that LSD has a mortality of 1-5% and a morbidity of 10-20% and can spread quickly if not handled properly. This study aimed to determine the prevalence of LSD and to identify associated risk factors in Pakem District, Yogyakarta. This research used a cross-sectional study. Samples were taken using a double-stage sampling technique with a total sample of 262 cattle. The study employed primary data collected through interviews with farmers. Data was analyzed descriptively and analytically. Data in the form of frequencies and percentages were analyzed using univariate methods. The relationship between risk factors and the incidence of LSD was analyzed using bivariate Chi-Square methods. The results showed that the prevalence of LSD in the Pakem District was 7.6%. The presence of ticks was identified as a risk factor for LSD disease, with a probability value of p<0.05. The association’s strength was indicated by an odds ratio (OR) of 2.64, suggesting that ticks may elevate the risk of contracting LSD by a factor of 2.64. The prevalence of LSD in Pakem District was 7.6%, and the presence of ticks 2.64 times increases the risk of LSD incidents. Control measures can be improved by carrying out livestock management in handling vectors.

Abstract

Colibacillosis remains a prevalent issue in breeder superior native chickens (KUB). This study aims to isolate, characterize, and assess the antimicrobial susceptibility of E. coli from breeder KUB chickens in Yogyakarta, Indonesia. Samples, including infertile eggs (n=113), day-old chick (DOC) deaths (n=53), drinking water (n=17), feed (n=25), eggshells (n=117), and fluff (n=113), were collected through random sampling from breeder KUB chickens. Isolation and identification of E. coli were carried out via biochemical methods, whereas serological tests were performed with antisera for O1:K1, O2:K1, and O78:K80. Hemolytic E. coli strains were identified through culture on blood agar, and antimicrobial susceptibility was evaluated via the disk diffusion method. A total of 31 E. coli isolates were obtained from various sources: infertile eggs (15.04%), DOC-contaminated eggs (13.20%), drinking water (35.29%), feed (8.00%), eggshells (8.00%), and fluff (20.25%). Among the isolates, 22.62% were hemolytic, and 77.38% were nonhemolytic. The serotype distributions were as follows: 11.9% O1:K1, 9.52% O2:K1, and 9.52% O78:K80. E. coli isolates were susceptible to tetracycline, oxytetracycline, enrofloxacin, and sulfamethoxazole but resistant to ampicillin, streptomycin, and erythromycin. E. coli, the causative agent of colibacillosis, has been isolated from KUB breeder chickens in Yogyakarta. Therefore, strengthening biosecurity measures and implementing effective antibiotic management strategies are crucial for mitigating the risk of antibiotic resistance.

Abstract

Background and Aim: Antibiotics are one of the most used treatments by farmers, both in commercial and non-commercial livestock operations. The use of antibiotics in animals directly impacts the environment, which can become a significant factor in the spread of antibiotic resistance. The environment plays an essential role for both animals and humans, and contamination caused by uncontrolled environmental factors can lead to health impacts on surrounding populations. One of the contaminants that can threaten the health of animals and humans is the presence of Escherichia coli. The aim of this study was to determine the antibiotic resistance profile of E. coli in environmental samples collected from a non-urban livestock region in Playen, Gunung Kidul Regency, Yogyakarta.Materials and Methods: The data in this study consisted of fifty samples, including fishpond water, wastewater, drinking water, water source, water tank, feces, and soil. The methodology involved bacterial isolation using biochemical tests and antimicrobial resistance testing conducted through the KirbyBauer disk diffusion method.Results: The antibiotics used in this study were streptomycin, penicillin, enrofloxacin, oxytetracycline, and sulfamethoxazole. The results showed that 5% of the samples were resistant to streptomycin, 92% were resistant to penicillin, 0% were resistant to enrofloxacin, 12.8% were resistant to oxytetracycline, and 2.5% were resistant to sulfamethoxazole.Conclusion: The findings indicate a high prevalence of Penicillin-resistant E. coli in environmental samples from non-urban livestock areas, highlighting the potential risk of environmental antibiotic resistance transmission.
