Judul: Efektivitas Asam Organik Cair dalam Menginaktivasi Virus Newcastle Disease
Abstrak: Penelitian ini dilakukan untuk mempelajari kemampuan asam organik cair dalam menginaktivasi virus Newcastle Disease (ND). Pengujian diawali dengan uji toksisitas asam organik pada embrio ayam menggunakan telur embrio tertunas (TET). Uji dilakukan menggunakan TET karena pengujian kemampuan inaktivasi asam organik terhadap virus ND dilakukan pada telur ayam berembrio. Uji toksisitas asam organik dilakukan dengan menginokulasikan asam organik konsentrasi 0%, 0.2%, 0.3%, dan 0.4% kedalam masing-masing 5 butir telur dengan rute ruang allantois. Peubah yang diamati pada uji toksisitas adalah daya hidup dan bobot badan embrio. Uji kemampuan inaktivasi asam organik terhadap virus ND dilakukan pada 50 butir TET yang dibagi kedalam 5 kelompok masing-masing kelompok 10 butir. Virus ND titer 105 EID50/mL diinkubasi sebanyak 2 mL dengan asam organik 0%, 0.2%, 0.3%, dan 0.4% sebanyak 2 mL kemudian di inkubasikan pada suhu 27 ºC selama 30 menit. Masing-masing suspensi diinokulasi kedalam 10 TET dan di inkubasikan selama 2-7 hari. Setelah 2 hari 5 butir telur dari masing-masing konsentrasi asam organik yang belum mati dimatikan dan diamati adanya pertumbuhan virus dan perubahan patologi anatomi serta bobot badan embrio. Sisa TET yang masih hidup di inkubasikan sampai hari ke 7. Pada hari ke 7 semua TET dimatikan dan diamati adanya pertumbuhan virus dan perubahan patologi anatomi serta bobot badan embrio. Hasil toksisitas menunjukkan bahwa asam organik konsentrasi 0.2%-0.4% tidak menyebabkan kematian embrio. Asam organik konsentrasi 0.2%, 0.3%, 0.4% masing-masing mampu menginaktivasi 50%, 100%, dan 90% virus ND. Dari hasil uji ini menunjukkan asam organik cair konsentrasi 0.3% dapat meninaktivasi virus ND secara in vitro.

Judul: Studi Kemampuan Vaksin ND-IB Lived: Pembentuk Kekebalan dan Perlindungan terhadap Paparan Virus Newcastle Disease pada Ayam Pedaging
Abstrak: The objective of this study was to measure the antibody titer of broilers were vaccinated with lived ND LaSota-IB H120 vaccine, and to observe the clinical signs and pathological lesions on challenged group. As much as 60 commercial Day Old Chicks were used in the experimental. Twenty chickens were bleed at day one to measure maternal antibody against Newcastle Disease (ND) using Hemaglutination Inhibition (HI) Test. The remaining fourty chickens were divided into four groups. Each group consisted of ten broilers. Group K1 and K2 were unvaccinated. Group K3 and K4 were vaccinated on the 2nd day according to the manufacture procedure. Challenge was carried out on 14th day (12th day post vaccination) to group K1 and K3 with ND Indonesia isolate virus. Blood samples from unvaccinated and vaccinated group were taken on 7th, 14th, and 22nd day. The result showed that chickens had high maternal antibody titer. The combination of intranasal and oral vaccination was able to produced protective antibody against ND viral infection. Vaccination was able to reduced lethargy and petechiae cecal tonsil. The clinical signs and pathological lesions were more severe on unvaccinated group.

Judul: Addition of preposition word graph generator module in bogor_delft_construct application
Abstrak: Knowledge graph is a new method used to analyze text and represent in a graph form. Word graph consists of concept and relation which represents the meaning of a word in a graph form. Ontology used in a word graph structure consists of 8 binary relationships, 4 frame relationships, and a focus. Bogor_Delft_Construct is an application that implements knowledge graph method to analyze text written in Bahasa Indonesia, However, this application still has some limitations in analyzing vocabularies such as prepositions. This research aims to add a module to the application that could generate word graph of preposition based on preposition patterns prosposed by Wulan (2009). The addition of preposition word graph generator module that was done in Bogor_Delft_Construct could recognize 23 prepositions which were followed by its auxiliary words. The preposition’s auxiliary words were divided into 12 documents; each has different nominative meaning.
