Avian Influenza (AI) virus is pathogenic agent that can spread from one area to another area through the transportation of infected animals or their products such as feathers. This research was aimed to inactivated AI virus with 775 ppm sodium hypochlorite and 0.1% chloroxylenol to examine the difference of treatment by time (day) for inactivation AI virus on the feathers. AI virus isolate A/chicken/sidrap/ 07160336‐2/2016 used in this research was obtained from Balai Besar Veteriner Maros. The treatment of disinfectants were performed on the first day (the day of disinfectan solutions were prepared), the third day and the seventh day by soaked the feathers in disinfectant solution for 10 minutes. The effectiveness of disinfectans were evaluated by inactivation index. The result show that the average of inactivation index of 775 ppm of sodium hypochlorit was 4.17 for the first day, 5.17 for the third day, and 4.20 for the seventh day, while the average of inactivation index of 0.1% chloroxylenol was 5.50 for the first day, 6.43 for the third day, and 5.77 for the seventh day. Our result indicated that the sodium hypochlorit and chloroxylenol were effective for inactivation of AI virus. The 0.1% of chloroxylenol was more effective for inactivation AI virus than 775 ppm of sodium hypochlorit, whilst the most effective duration for the treatment is the three days.

The Mx gene is an antiviral gene used to determine the resistance or the susceptibility to different types of viruses, including the Avian Influenza (AI) virus subtype H5N1. The AI virus subtype H5N1 infection in chickens causes Mx gene polymorphism. The Mx+ gene shows resistant to the AI virus subtype H5N1, whereas the Mxgene shows signs of susceptible. The objective of this research was to detect the Mx gene in wild aquatic birds using the Polymerase Chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) method with the primer pairs F2 and NE-R2/R and the RsaI restriction enzyme. DNA samples were obtained from eight species of wild waterbirds with positive and negative exposure to the AI virus subtype H5N1. DNA amplification results showed that the Mx gene in wild aquatic birds is found in a 100 bp fragment, which is the same as the Mx gene found in chickens. However, unlike chickens, the Mx gene in wild aquatic birds did not show any polymorphism. This study proves that Mx- based resistance to AI virus subtype H5N1 in different in wild birds than in chickens.

Avian Influenza (AI) is one of the strategic animal diseases still considered a priority for control by the Indonesian government. This study aimed to examine the immune response of chickens to various types of H5N1 subtype AI vaccines in Indonesia and to determine the correlation of factors influencing the post-vaccination AI antibody response. Serum samples were tested using the hemagglutination inhibition (HI) test with the standard AI antigen subtype H5N1 strain A/Chicken/Barru/BBVM/41-13/2013 (Clade 2.1.3) and strain A/Chicken/Semarang/04141225-07/2014 (Clade 2.3.2). Antibody titer was calculated using the Geometric Mean Titer (GMT). The correlation analyses were performed to assess the correlation of antibody titer against each of the following factors: age of chicken at the time of sampling, the interval between sampling time and the previous vaccination, and the number of vaccinations performed. The results showed that the average antibody titer value against the AI antigen subtype H5N1 strain A/Chicken/Barru/BBVM/41-13/2013 (Clade 2.1.3) was highest in samples from the South Sumatra Province, namely, Palembang City, which was 26.42 HIU. The results showed a significant correlation (p-value <0,05) between antibody titer and the interval between sampling time and the previous vaccination, the number of vaccination performed and age of chicken at the time of sampling. Therefore, results showed that the immunity developed from vaccination using the AI vaccine seed subtype H5N1 could induce immunity with a protective value of ≥16.

Antibody production is becoming a trend, especially during a pandemic like now, although there have been many developments in antibody production in previous research. Antigen synthesis and characterization is one of the determining factors for the success of antibody production. This research developed a method of antigen characterization using the Nuclear Magnetic Resonance (NMR) method. The research conducted in these 4 stages begins with antigen synthesis, then continues with antigen characterization using NMR, then antibody production, and the last stage is antibody characterization using the Enzyme Linked ImmunoAssay (ELISA) method. The results of antigen characterization using NMR show that NAS has been perfectly conjugated with BSA and produces a NAS-BSA conjugate. This is shown by the presence of 1 methylene (CH2) olefinic at δH chemical shift of 6.27 ppm with an integral of 4 and having 1 piece of methine (CH) sp2 at δH chemical shift of 5.73 ppm with an integral of 2. NAS-BSA antigens have been shown to successfully produce antibodies. This is shown from the anti-NAS-BSA, NAS, and Acrylamide antibodies that begin to appear in the second, third and fourth boosting (respectively)

Abstract This study aimed to evaluate the acceptance and effectiveness of an Augmented Reality (AR)-based English language learning system, ELSA, among students. Through the analysis of Technology Acceptance Model (TAM) questionnaire data and statistical tests, it was found that students had a positive perception of the usefulness and ease of use of the AR system. The use of ELSA significantly improved students' English language proficiency, particularly in vocabulary and pronunciation. Moreover, ELSA was also able to increase student motivation. However, this study identified disparities in student abilities and a lack of relevance of the material to the local context as challenges. Efforts have been made to address these issues, such as adjusting learning groups and revising materials. Overall, the results of this study demonstrate the great potential of AR in revolutionizing English language learning, especially for young learners, by providing a more interactive, personalized, and effective learning experience.
