Judul: Implementasi program teks-ke-wicara pada kamus bahasa Indonesia-Inggris
Abstrak: Kemajuan teknologi komputer memungkinkan adanya program yang mampu mengucapkan kalimat berdasarkan input teks. Untuk mampu mengucapkan kalimat, program ini mengggunakan teknologi sintesis wicara. Sintesis wicara diaplikasikan pada komputer oleh sistem Teks-ke-Wicara dengan memanfaatkan multimedia. Pada tingkat yang sangat canggih sistem Teks-ke-Wicara telah diaplikasikan antara lain pada sistem robot. Sedangkan pada tingkat yang sangat sederhana, sistem ini dapat digunakan pada program kamus yang dapat mengucapkan kata. Tahapan yang harus dilalui sistem Teks-ke-Wicara yaitu normalisasi teks, homograph disambiguation, pengucapan kata, sintesis intonasi dan pembangkitan suara. Normalisasi teks merupakan sebuah pre- proses yang menginterpretasikan singkatan, angka, akronim, waktu, tabel, formula serta bentuk lainnya menjadi rangkaian huruf alfabet. Homograf disambiguation merupakan tahap khusus untuk mencari bentuk pengucapan homograf. Tahap pengucapan kata menguraikan teks menjadi rangkaian fonem. Untuk mendapatkan bentuk pengucapan suatu kata, sistem teks-ke-wicara pertama kali mencarinya pada leksikon. Jika tidak ditemukan pada leksikon, maka aturan huruf-ke-suara digunakan untuk menentukan pengucapan kata. Tahap sintesis intonasi bertujuan untuk menyertakan intonasi pada suara yang dihasilkan. Intonasi dibangkitkan melalui pemodelan intonasi. Tujuan utama dari model intonasi adalah membuat sistem deskripsi intonasi. Tahap pembangkitan suara menerima rangkaian fonem untuk diucapkan, mengambil suara digital dari database dan melakukan penyesuaian nada, waktu (durasi) dan volume kemudian mengirimnya ke kartu suara. Pada penelitian ini penulis mengaplikasikan sebuah sistem Teks-ke-Wicara Whistler yang dikembangkan oleh Microsoft pada sebuah program kamus bahasa Indonesia-Inggris. Whistler merupakan sekumpulan Speech Application Program Interface (SAPI). Untuk mengorganisasikan data kamus pada memori digunakan struktur data AVL Tree. Operasi pencarian, penyisipan dan peghapusan node pada AVL Tree memiliki kompleksitas O(Log n).

Judul: Transkripsi Suara ke Teks Bahasa Indonesia Berbasis Suku Kata Menggunakan Codebook dan 2-level Dynamic Programming
Abstrak: Voice to text transcription is very useful because it allows people to interact with a system more quickly. However, it is hard for a system to recognize a speech which contains of connected words. This research aims to develop a system that recognize a connected word speech. The proposed approach uses MFCC as a feature extraction, codebook as pattern recognition method, and 2-level dynamic programming as connected words recognition method. The parameters used in feature extraction using MFCC are overlap, time frame, and number of cepstral coefficients. Moreover the parameter used in K-means clustering is the number of clusters. This research uses 900 syllable’s speech data from 18 classes, and 120 connected word’s speech data which consist of 60 testing data joined from training data and 60 real testing data. The results showed that the optimum value of K was 15, with the minimum word error rate of 0.1 for the ‘Ide Anda’ words resulted from joining words of training data with the overlap value of 0.25, the time frame value of 25 ms, the number of cepstral coefficients of 13, and the number of clusters of 20.

Judul: Physiological Status, Haematocrite, Blood Mineral Plasma in Sheep Infected with Gastrointestinal Nematodes and Offered 50% Concentrate.
Abstrak: Fourteen species of gastrointestinal nematodes may infect sheep and reduce their productivity. Haemonchur contorius is the main cause of anemia in sheep. with high prevalence level of about 80%. Commercial anthelmintic is expensive and its residue may create the problem. Evaluation of alternative methods to prevent infection of nematode is necessary. Nematode infection could be reduced by improvement of Feeding balance ration and early detection of early symptoms may reduce the intensity afnemalode infection. The present experiment was conducted to detennine physiological status. blood haematocrite and mineral Ca and Mg plasma of sheep infected by gastrointestinal nematodes and offered 50% concentrate with or without Zn supplementation. Thirty six of sheep having an average initial live weight of 12.06±1.7 kg were used in the present experiment. The sheep were grouped and allocated into three treatments: 8 sheep were in TO (control), 8 sheep were in TI (infected + 30 ppm Zn supplement), and 20 sheep were D (infected). Sheep were offered hay of Pennisetum purpureum and concentrate (50:50 dry matter basis) at rate of 4% oflive weight. Drinking water was offered ad libitum. At the heginning of the experiment, the sheep were treated with a commercial anthelmintic (toloxan®) at a dose of 5 mllhead. Sheep were infected by 5,000 L3 phase nematode larva conslstmg of 80% Haemonchus con/ortus. 9% Trichostrongylus. 6% Cooperia and 5% Oesophagostonum. On the day of 18th after infection. egg count per gram feces were detennined by McMaster method at sensitivity of 1:100. A complete randomized uuhalance design was used to compare the effect of treatments on physiological status, haematocrite, and Ca as well Mg plasma. used McMaster method. Reduction value (RY) of egg count per gram feces was calculated based on a formula as follows: RV ~ (1- (K1/P1*P2/K2))*100%. Result showed that nematode infection changed the physiological status of sheep fed ration which with or without Zn supplementation. Heart beat rate increased significantly (p<0.05) on TO compared with TI and D. Rectal temperature, respiratory rate, blood haematocrite, Ca and Mg plasma were not significantly altered by nematode infection. Key Words: nematode. mineral, physiology and hematocrite.
