Judul: Search Engine Dua Bahasa Berbasis Kamus Menggunakan Sphinx Search
Abstrak: Cross Language Information Retrieval (CLIR) systems allow users to input the keywords in their own language and then the system will retrieve the relevant documents that written in the other language from database. This research implements a CLIR system that will retrieve relevant documents in Bahasa Indonesia and English by entering the query in Bahasa Indonesia or English. In order to translate the query, we use bilingual dictionaries. For indexing and retrieval process, we use BM25 and proximity algorithms from Sphinx. Performance of the system is determined using recall and precision with maximum interpolation. In the evaluation we conduct comparisons among Bahasa Indonesia search engine, English search engine, and Bilingual search engine. The test results show that the performance of monolingual search engine is better than bilingual search engine. The influence factors are the amount of translations, the combination of the wrong translation, and the amount of the document collections

Judul: Query Expansion on Indonesian Information Retrieval System using Bilingualism Dictionary.
Abstrak: The most frequent problem on information retrieval is the users inability in representing information they need, in a query form. Thus, one of the solutions to overcome such situation is by applying query expansion technique. By applying the method, query will be expanded, and the new query produced will be used to do the search task. One of the approaches in determining the term of the expansion is Translation with Bilingualism Dictionary, which works through query translation process using dictionary, and the calculation of weight from each expanded candidate terms. In order to increase the relevance of the search result, this research uses Translation with Bilingualism Dictionary as the method to apply. Acknowledging the influence of the method, the research trial and error through the observation of the eleven recall precision number is applied to the produced retrieval result by using different expansion terms. Based on the observation of the produced precision number, it is identified that the use of Translation method in this research has not been successfull in increasing the relevance of the search results. The more expansion terms used, the smaller the precision number produced. Keywords: query expansion, query translation, information retrieval, bilingualism dictionary

Judul: Pengaruh tingkat asetilasi terhadap daya tahan papan partikel dari serangan jamur pelapuk kayu
Abstrak: Papan partikel dapat dibuat dari semua jenis kayu dan tidak membutuhkan persyaratan bahan baku yang tinggi. Salah satu jenis kayu yang dapat digunakan sebagai bahan papan partikel ini adalah Kayu Karet (Hevea brasilliensis Muell.Arg.). ersity Papan partikel yang terbuat dari kayu karet memiliki sifat higroskopis sehingga menimbulkan kelemahan yang berarti yaitu stabilitas dimensinya yang rendah dan memiliki resiko kerusakan yang lebih besar terutama oleh serangan bakteri, jamur dan mikroorganisme lainnya. Perlakuan pendahuluan terhadap partikel kayu berbentuk selumbar (flake) merupakan suatu usaha untuk memperbaiki sifat papan partikel, sebelum partikel mengalami proses lebih lanjut. Salah satu bentuk perlakuan pendahuluan ini adalah dengan menggunakan bahan kimia, dalam hal ini adalah anhidrida asetat (asetilasi). Penelitian ini bertujuan untuk mengetahui pengaruh asetilasi pada tingkat persen penambahan berat (Weight Percent Gain, WPG) yang berbeda pada papan partikel kayu karet terhadap serangan jamur pelapuk kayu Schizophyllum commune Fr. ...
