Judul: Penelusuran data melalui pengenalan ucapan
Abstrak: Ada dua aspek dalam pengenalan ucapan, yaitu pengenalan kata dan pengenalan maksud. Pengenalan kata berkaitan dengan proses dari penerimaan sinyal masukan, proses digitasi, hingga pemodelan kata yang digunakan untuk pengenalan. Selanjutnya, dari kata yang dikenali tersebut dilakukan pengenalan maksud sesuai domain permasalahan yang telah ditetapkan. Untuk penelusuran data, pengenalan maksud adalah penerjemahan masukan menjadi bahasa query yang valid dengan menggunakan context-free grammar. Metode penelitian mengacu pada pendekatan sistem, meliputi perancangan, implementasi, dan pengujian sistem. Hasil pengujian menunjukkan bahwa tingkat pengenalan kata secara umum masih di bawah 90%, dengan tingkat pengenalan maksud mendekati 100%. Hal ini menunjukkan bahwa sistem mampu mengakomodasikan semantik dari rangkaian kata meskipun terjadi kesalahan pada rangkaian kata hasil pengenalan. Kata Kunci: pengenalan ucapan, context-free grammar

Judul: Hybrid Jaringan Syaraf Tiruan dan Model Markov Tersembunyi Untuk Pengenalan Bilangan Berbahasa Indonesia Menggunakan CSLU Toolkit
Abstrak: Sistem pengenal kata untuk bahasa Indonesia masih sangat minim dalam pengembangannya, khususnya dalam penerapannya sebagai pengenal bilangan (Continuous Digit Recognizer CDR). Penelitian ini membandingkan metode pengenalan kata menggunakan data hand-labeled, force alignment, dan Forward Backward Neural Networks (FBNN) pada pengenalan bilangan berbahasa Indonesia menggunakan CSLU toolkit. Penelitian dilakukan dengan bantuan CSLU toolkit, dengan berfokus pada akurasi pengenalan pada tingkat kata dan kalimat. Kata-kata yang dapat dikenali terbatas pada kata dasar bilangan sesuai dengan ejaan bahasa Indonesia yang disempurnakan.

Judul: Hybrid solar cells of ZnO nanoparticles/chlorophyll was modified metal ions (Zn2+ and Cu2+ )
Abstrak: Zinc Oxide (ZnO) is a n-type semiconductor with a wide the energy band (Band Gap) is 3.37 eV at room temperature and 3.34 eV at low temperature with a large exiton binding energy is 60 meV. ZnO has been synthesized by hydrothermal method, resulting in a decrease in particle size over the duration of the hydrothermal changes. Crystallographic structure of ZnO were characterized using XRD, has shown the characteristic pattern of a hexagonal wurtzite structure, the crystallite size increases to changes in particle size. Changes in particle size has also led to a change in the absorption peak of ZnO as has been demonstrated posted under test using the optical properties of UV-Vis spectrophotometer. Changes of this uptake has also led to changes in the energy band gap, which increases its band gap energy of the particle size. In electronic applications, especially in solar cells. Chlorophyll is considered less effective, because of their very nature are easily degraded as a result of several reactions which are acid, lighting and temperature. The results of the stability test using a halogen lamp 34 W/m2 for 5 hours, that the substitution of chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form more stable than natural chlorophyll. The characterization of the optical properties, the combination of ZnO / chlorophyll in the form of hybrid films has led to a shift in the absorption region of ZnO becomes more widely from the UV to Visible. ZnO/chlorophyll has absorption range of 350-515 nm, ZnO / Zn-feofitin 332-401 nm and 332-632 nm for Cu-feofitin. The combination of ZnO/chlorophyll and CuSCN as a solid electrolite in hybrid solar cell, a modified chlorophyll with metal ions Zn2+ and Cu2+ has been shown to form a more stable I-V curve. It is characterized by its fill factor value greater than natural chlorophyll. Nevertheless, solar cells with natural chlorophyll has been able to produce higher efficiency values of chlorophyll were substituted.
