Judul: Implementasi Pengenalan Suara dalam Pencarian Ayat-Ayat al-Quran Menggunakan MFCC dan Codebook
Abstrak: Pencarian teks ayat-ayat al-Quran tidaklah mudah dikarenakan dibutuhkan keahlian khusus dalam pengetahuan bahasa Arab. Oleh karena itu, dibuatlah sebuah sistem pencarian teks ayat-ayat al-Quran dengan bantuan transkripsi suara agar mempermudah pencarian ayat-ayat al-Quran. Dengan menggunakan MFCC sebagai ekstraksi ciri, suara diubah menjadi sebuah data vektor yang dapat dicirikan dan dijadikan sebuah codebook. Penelitian ini bertujuan untuk mengimplementasikan pengenalan suara ke dalam sebuah sistem pencarian teks al-Quran. Terdapat 4 potongan ayat Al-Quran yang akan diidentifikasi ke dalam ayat-ayat yang mengandung potongan ayat terebut. Penelitian ini berhasil menghasilkan sebuah sistem yang dapat mendeteksi potongan ayat al-Quran pada sebuah ayat dengan akurasi sebesar 85%

Judul: Sistem Pencarian Ayat Al-Quran Berbasis Kemiripan Fonetis
Abstrak: Searching Arabic text in the Holy Quran is not easy for users that do not have sufficient knowledge about Arabic language and script. Therefore, phonetic search can be used to facilitate users to search in the Holy Quran with their pronunciation represented in Latin script using regular alphabets. This research aims to build such search system, specifically for speakers of Bahasa Indonesia. A phonetic coding method regarding Quran recitation rules (tajweed) is proposed to match between Quran texts in Arabic script and user's queries in Latin script. Indexed trigram is used for approximate string matching. The system uses two search schemes: vowelized and non-vowelized search; two ranking methods: trigram count and trigram position ranking; and two search purposes: pronunciation and topic search. Experiment using user-generated queries and given relevance judgments shows that vowelized search performs better than non-vowelized search with 0.651 average precision (AVP) at the cost of longer search time. Trigram count ranking performs better than trigram position ranking with 0.668 AVP, although trigram position ranking can obtain higher precision at lower recall level. Pronunciation search queries perform better than topic search queries with 0.751 AVP.

Judul: Studies on growth spurt and aging in higher primates
Abstrak: single measurement that best defines the health and nutritional status of children, just as it provides an indirect measurement of the quality of life of an entire population. The pattern of human growth reflects the biocultural evolution of our species. The human pattern of growth and development (ontogeny) appears to differ markedly from patterns of ontogeny in other primate species. Three studies are reported here which deal to the growth and development of human and chimpanzee (Pan troglodytes). These three studies allow us to contrast the phenomena of adolescence growth spurt and female elderly bone loss in chimpanzee and human as chimpanzee is the closest species to humans within extant nonhuman primates. In the first, a cross-sectional study of growth of the body size and somatotype of 363 Javanese girls and 299 Javanese boys aged 4 to 20 years from Magelang Regency, Indonesia was described. In the second, cross-sectional and longitudinal studies in the growth of chimpanzee second metacarpal bone linear dimensions from individuals aged 0 to 43.6 years were used for comparison. While in the third, cross-sectional and longitudinal studies in the growth of chimpanzee body size (body mass and anterior trunk length) and second metacarpal bone mineral content were derived. In measuring the second metacarpal dimensions and mineral content, a total of 568 radiographs of chimpanzee's proximodistal left hands were used. They were taken from 68 females and 49 males aged 0 to 43.62 years old. We applied an image analysis system, Scion Image Release Alpha 4.0.3.2 software for Windows to measure bone linear dimensions and bone mineral content. Humans present complex and sinuous growth curves for both body weight and height. A clear growth spurt could be demonstrated by cross-sectional analysis in our girl subjects at around aged 11.5 years and in our boy subjects at around aged 12.5 years. In longitudinal series, not in cross-sectional, several representative chimpanzees of both sexes showed a pre-adult growth spurt on the body sizes, bone dimensions and bone mineral content. They ranged at age 4.5 to 8.5 years. This underscore the fact that adolescent growth spurt in linear dimension was not a universal feature of anthropoid primate ontogeny. Bone loss is a well established characteristic of human female aging. Based on crosssectional analyses the sequential decline of bone mass in female chimpanzee may be said to be genuine. On the other hand, we found in adulthood through elderly, male chimpanzees show a longer plateau than female chimpanzee, that is, bone mineral content is maintained in male.
