Judul: Pencarian Informasi Dengan Metode Trigram
Abstrak: Unluk mencari suatu informasi yang berbasis teks biasanya dibutuhkan atribut-atribut tertenlu, dalam hal ini judul, nama peneliti, penerbit, dan tahun terbit. Untuk rekord berisi teks seperti judul dokumen, abstrak alau ringkasan suatu dokumen, identifikasi yang digunakan adalah kata kunci atau kata indeks dari sualu dokumen. Pada saat jumlah kala yang dipunyai semakin banyak, proses lemu kembali yang dilakukan akan membutuhkan waktu yang cukup lama, juga media penyimpanan di kompuler. Pada penelitian ini Inverted file digunakan sebagai tempat menyimpan sekumpulan dokumen yang dicirikan olch sekumpulan istilah. Sedangkan algoritme trigram dipakai sebagai algoritme untuk memeriksa istilah dalam quely yang mirip dengan istilah dalam basisdata.

Judul: Sistem Temu Kembali Nama Ilmiah dengan Menggunakan Algoritme Fonetik
Abstrak: This research did document retrieval by its scientific name as the search keywords. The approach was taken by using the phonetics algorithm, Soundex, Phonix, and Metaphone. The purpose of this research is to apply the three algorithms phonetic similarity with combined technique, in terms of using exact matching, binary (N-Grams), and levensthein distance. So that expected to overcome the issue by using the search word two syllables. Documents used in this research were 100 documents that have been tagged. The word that has been tagged will be converted into specific code in accordance with phonetic algorithms, which will be calculated similarity with the input word. Search scientific name combined with similarity techniques succeed to solve the problem, whether it’s wrong typing or spelling words wrong as well as similarities in handling the search by using two syllables. This is indicated by the percentage of average precision (AVP) from the search result is equal to 77.8% (Soundex), 88% (Phonix), and 97.5% (Metaphone).

Judul: Antibody Responses against Newcastle Disease and Evaluation of Infectious Bronchitis Maternal Derived Antibody on Vaccinated Layers.
Abstrak: Information of maternal derived antibody (MDA) and onset of immunity after vaccination is important to determine appropriate vaccination programme of chickens. The aim of this study was to evaluate duration of Infectious Bronchitis (IB) MDA and evaluate onset of immunity Newcastle Disease (ND) vaccination among layers. All layers were vaccinated using live ND and Infectious Bursal Disease (IBD) at one day old age, and received Avian Rhinotracheitis (AR) vaccine at 4 day old age. Serum samples were collected at various ages: 7, 10, 14, 20, 22, 24, 29 and 35 day old. The presence of ND antibodies was measured by the hemagglutination inhibition (HI) test, whilst the presence of IB antibodies was measured by enzyme-linked immunosorbent assay (ELISA). Our study showed that ND antibodies were at positive level until 24 day old age, and reached protective level ≥ 25 only at 7 day old age, whilst IB MDA were positive up to 17 day old age. This result indicating the needs of ND booster vaccination at least at 24 day old and IB vaccination at 17 day old age.
