Abstract

The Argulus sp infection in freshwater fish including tilapia (Oreochromis niloticus) causes the serious problem in aquaculture. Despite the scarce of the preventive action in parasite infection, the application of salt mostly have been done in fish farming to overcome these parasites. The sodium chloride (NaCl) was used in farm because it was safe for water environment as well as it was inherent therein. The effectiveness of sodium chloride to control ectoparasites Argulus sp in tilapia juvenile was tested in laboratory. The fishes were infected by Argulus sp. and they are treated short term dip with three doses of sodium chloride namely 3 ppm, 6 ppm and 9 ppm for ten days. The  prevalence of parasites, the parasites intensity, and survival rate were examined and the results  were evaluated using statistic. The result showed that the NaCl salt application significantly affected the prevalence, the parasite intensity and the survival rate of fishes. The best dose that give the lowest prevalence, the lowest parasite intensity and the highest survival rate was the G3 (9 ppm dose).

Abstract

Bacteria from animals raised for food that have developed antimicrobial resistance (AMR) may serve as a vehicle for its transmission from animal to human. Nevertheless, the antibiotic resistance profile of Escherichia coli from raw meat is scarcely reported, especially in North Sumatra. The aim of this investigation was to investigate the retail raw meat for the presence of E. coli and its antimicrobial resistance pattern. We purchased 80 packages of fresh meat products from four traditional markets located in Deli Serdang and Medan. Escherichia coli was isolated by an established microbiology test and a phenotypic antimicrobial susceptibility test was conducted by the method of disk diffusion. The data analysis of antibiotic resistance and multi-drug resistance (MDR) levels was performed by using WHONET 5.6. The antibiotic resistance dissimilarity between the two regencies was analyzed by using chi-square analysis. This study observed about 19 E coli isolates (23.7%) were obtained from raw meat. Resistance toward the antibiotics listed as critically important for veterinary and human therapy is increasing concern for public health. The isolates were highly resistant to ampicillin and tetracycline. Meanwhile gentamycin is susceptible. The MDR level of E. coli in both regencies of North Sumatra was about 21.05%. This finding contribute essential information on AMR in food animals and can be used to improve local and regional plans for the administration of antibiotics to livestock.

Dewi, R.R, Sihombing, J.M., & Ma’arif, I. (2024). A Survey of health manajemen practices on livestock farm located in Binjai, North Sumatra. In: Herlinda S et al. (Eds.), Prosiding Seminar Nasional Lahan Suboptimal ke-12 Tahun 2024, Palembang 21 Oktober 2024. (pp. 69–75). Palembang: Penerbit & Percetakan Universitas Sriwijaya (UNSRI).Practicing good health management in livestock is critical in controlling infectious diseases in livestock. This study attempts to evaluate the health management practices implemented by ruminant farmers in Binjai, North Sumatra. The study aimed to was carried out utilizing a survey method combined with interview techniques and field observations. This study included 56 ruminant farmers who raised cattle (37; 66.1%), goats (14; 25%), and sheep (5; 8.9%). The findings of this study revealed that approximately 68% of farmers have implemented sanitation and disinfection on their farms, whereas only a small percentage of farmers have received animal health training (8.9%), and there is little veterinary support in dealing with disease (16.1%). In treating their animals, farmers use anthelmintic drugs about 26.8% and the majority of farmers prefer antibiotics (42.9%) to herbs (7.1%) There is no significance difference between farmers' knowledge about health and sanitation application, veterinarian supports and drugs application among farmers. The majority of Binjai farmers have implemented farm sanitation measures. However, most farmers who have inadequate knowledge of livestock health have no support from veterinarians in diagnosing and treating the diseases. This possibly leads to inappropriate use of drugs by farmers. Farmers in Binjai should receive training regarding livestock health management to elevate a sustainable livestock productivity.

Abstract

The cultivation of Trigona honey bees by the "Kelompok Tani Peduli Pesisir" (Coastal Care Farmer Group) has strong potential for rapid development due to the abundant availability of food plants that support the life of kelulut bees (Trigona spp.), particularly from home gardens in mangrove areas. The diversity of plant species is crucial for ensuring a steady supply of nectar, pollen, and resin, which directly impacts honey production. However, limited community knowledge about suitable plant species and the lack of plant variety pose challenges to sustainable Trigona spp. beekeeping. This community service initiative aims to introduce potential food sources for kelulut bees and provide plants to enrich the variety of feed sources, ensuring availability year-round. Activities include 1) preparing plant materials and planting media, 2) planting fruit trees, and 3) conducting educational outreach. As a result, farmers’ knowledge and the diversity of beneficial perennial plants such as mango (Mangifera indica), jackfruit (Artocarpus heterophyllus), and water apple (Syzygium aqueum) have increased, contributing to the sustainable development of Trigona spp. bee cultivation.
