Judul: Pemadanan Kode Fonetis Secara Otomatis antara Aksara Arab dan Aksara Latin Menggunakan Transliterasi.
Abstrak: Aplikasi seperti IslamiCity dan Lafzi menerapkan sistem pencarian fonetis yang memungkinkan pencarian teks Arab di dalam Alquran menggunakan aksara Latin. Kedua aplikasi tersebut menggunakan aturan pemadanan aksara Arab-Latin tertentu untuk membuat kode fonetis sehingga hasil pencarian tidak sesuai untuk pengguna yang memiliki referensi padanan aksara yang berbeda. Transliterasi dapat digunakan untuk membantu membangkitkan kode fonetis secara otomatis dengan menggunakan algoritme silabifikasi. Penelitian ini bertujuan untuk menghasilkan pengodean fonetis secara otomatis pada aplikasi Lafzi serta membandingkan kinerja sistem dengan kinerja sistem Lafzi berkode manual untuk penutur asli bahasa Indonesia. Sistem menggunakan 2 skema pencarian (pencarian vokal [V] dan tanpa vokal [N]) dan 2 metode pemeringkatan (pemeringkatan jumlah trigram [J] dan posisi trigram [P]) sehingga terdapat 4 skema pengujian: NJ, VJ, NP, dan VP. Pengujian menggunakan 821 variasi query yang didapat dari responden serta diberikan relevance judgments. Hasil pengujian menunjukkan bahwa kinerja sistem bekerja dengan baik tanpa penurunan kinerja yang signifikan. Nilai average precision (AVP) untuk skema NJ, VJ, NP, dan VP secara berturut-turut adalah 0.644, 0.651, 0.607, dan 0.627.

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: Phylogeography and Species Limits in the Papuan White Snake (Micropechis ikaheka) (Reptilia: Serpentes: Elapidae)
Abstrak: Papua white snake, Micropechis ikaheka, has been distingushed into two subspecies M.i. ikaheka and M.i. fasciatus. However, due to lack of data on their morphology, distribution and ecology, both subspecies often ignored in scintific discussions and refers only byas , Micropechis ikaheka. This study was designed to document the differences between M.i. ikaheka and M.i fasciatus by using scales characteristics and reproductive organ or hemipenes. The study also examine, zoogeography, habitat, diet and cannibalism of both subspecies to better understanding the the ecology of one of the most venomous snakes in the world. This study consists of three topics with method and also different in the size samples, respectively. The first study is the histology and microtopography of the skin were studied using paraffin method and Scanning Electron Microscope (SEM). The second is the hemipenis were examined by following Myers and Cadle (2003), and Zaher and Prudente (2003). The third is the abdominal surgery was carried out to document diet type and the investigate phenomenon of cannibalism in the snake. Specimens for this study came from the collection from Museum Zoologicum Bogoriense (MZB) and Universitas Negeri Papua’s Laboratory (LZU). The research result also indicated that the markers of skin and hemipenis described the same structure and microornamentation in all M. ikaheka groups being compared. Based specimens examined morphological descriptions do not s support the further differentiation in Micropechis. In short, two markers that used in this study could not sufficiently indicate the differences in the level of species and subspecies of M. ikaheka. The study, however, were able to delineate zoogeography and skin color patterns, which fall into four groups: M. i. ikaheka; M. i. fasciatus. M. i. ssp. “intermediate”; and M. i. ssp “black”. This study also revealed that color variations did not overlap in their geographic distribution. It is therefore, it suggested that environmental factors may contribute to the skin color variations. It also assumed that habitat discontinuous and biogeography factors may also cause the loss of the connection between the original populations (vicarians) or follow colonization events (dispersal). The examined of 22 stomach contents of M. ikaheka shows this species is carnivorous, and prey on vertebrates such as amphibians, fish, reptiles, and Mammals. These snakes are opportunistic predators since they prey on all that can be captured, but mainly reptiles (61.5%), followed by mammals and fish (both 15.4%), and amphibians (7.7%). Although categorized as terrestrial animal, the diet study showed that M. ikaheka snakes often go into the water to hunt for fish (the sample from Yapen island), including eel (the sample from Aru island). Based on prey items indentified, there is evidence that M. ikaheka is cannibal. At this time, there still no record on reason for cannibalism, but it is assumed that cannibalism was due to competition between populations and means to control population.
