Preparation of avian influenza H5N1 and Newcastle disease antigens for hemagglutination inhibition assay applications
No full textBackground Avian influenza (AI) and Newcastle disease (ND) are major poultry diseases in Indonesia, where monitoring of vaccination efficacy commonly relies on the hemagglutination inhibition (HI) assay. The HI assay requires viral antigens, which are generally obtained commercially from PUSVETMA. However, independent antigen preparation would be beneficial for private laboratories.
Objective This study aimed to prepare and validate in-house AI and ND antigens as HI assay reagents.
Methods Viruses were propagated in embryonated chicken eggs (ECE), inactivated using buffered neutral formalin (BNF), precipitated with polyethylene glycol (PEG-6000), and preserved with glycerol. Validation was conducted by parallel HI testing of 24 chicken sera for AI and 22 chicken sera for ND using both in-house and PUSVETMA’s antigens. Antibody titers were analyzed using analysis of variance (ANOVA), with sensitivity (Se), specificity (Sp), and kappa (κ) tests performed for agreement.
Results ANOVA revealed no significant differences in geometric mean titers between in-house and PUSVETMA’s antigens (P<0.05). Both the AI and ND in-house antigens demonstrated Se and Sp values of 100% and κ values of 1, indicating perfect agreement.
Conclusion These findings confirm that in-house AI and ND antigens are comparable to their commercial counterparts and can serve as reliable and cost-effective reagents for HI testing in private laboratories

There are gaps in author collaboration and thematic focus. Furthermore, some studies still focus on separate theoretical models. This study is expected to contribute to the accounting literature and serve as a reference for more innovative and contextually relevant further research
Analisis Ikon, Indeks, dan Simbol Semiotika Karakter Juki dalam Naskah Sumur Tanpa Dasar Karya Arifin C. Noer
No full textThe theory of semiotics was first coined by two experts, namely Ferdinand de Saussure and Charles Sanders Peirce. In this research, the author uses descriptive qualitative method with Peirce's semiotic approach. The object of this research is the play Sumur Tanpa Dasar by Arifin C. Noer. Sumur Tanpa Dasar is a play that was first performed in 1964 in Yogyakarta. The results show that Juki's character depicts deep symbols about the absurdity of life, time travel, complicated relationships, and thirst for freedom. Of the three forms of signs, icons are found the most. This research makes a new contribution by examining Sumur Tanpa Dasar from the point of view of Peirce's semiotics, which was previously analyzed more with structural approaches and literary psychology. This research is relevant for the development of literature, philosophy, and art studies, as well as a reference for similar research in the future.ABSTRAK
