Judul: Rancangan Sistem Authority Control di Perpustakaan Nasional RI
Abstrak: Authority control merupakan bentuk temu balik yang konsisten dari istilah unik yang digunakan sebagai istilah kendali dan penggunaan cross reference dari istilah yang tidak digunakan namun saling terkait, sehingga dapat meningkatkan hasil temu kembali informasi. Perpustakaan Nasional RI (Perpusnas RI) sebagai lembaga negara yang bertugas di bidang perpustakaan perlu mengembangkan sistem authority control yang efektif yang menjadi bagian dari sistem informasi di Perpusnas RI, yaitu Integrated Library System (INLIS). Sistem authority control ini dapat dijadikan alat atau sarana bagi pustakawan dalam menentukan keseragaman akses pada katalog sehingga terdapat konsistensi dalam penentuan titik akses informasi dan dapat meningkatkan hasil temu kembali informasi. Rancangan sistem authority control dalam penelitian ini menggunakan metode System Development Life Cycle (SDLC) yang terdiri dari studi kelayakan, investigasi sistem, analisis sistem, desain sistem, implementasi, review dan maintenance, dan telah selesai sampai tahap implementasi, yaitu pembuatan prototipe untuk penelusuran dan pemasukan data authority yang terdiri dari tajuk subjek, tajuk nama pengarang, dan tajuk badan korporasi.

Judul: Effectiveness Authority Control of The National Library of Indonesia
Abstrak: Many parties realize that the major problem has shifted from how to access information into select information. Increased collection and information make this activity can‟t be done manually. To solving it, librarian developed a system to control and find term each other called authority control. The concept of this system is controlling the term with a specific structure and designed to control synonyms, to distinguish homograph, cross-reference have the same meaning and terms are not used. A good data base authority is the key for effective searching in the catalogue. The purpose of this study is to analyze term structure relationships and to devise a concept of effective authority to the National Library by referring to the concept of Library of Congress Authorities. This research uses quasi-experimental methods that combined with comparative, by testing search term on the National Library of Indonesia authority and compare with the Library of Congress Authorities. It was found that term structure relationship on the authority of the National Library of Indonesia has not been functioning properly, as evidenced still not appropriate with the authority control procedure. From processing data got by conclusion that ratio of effective searching at Library of Congress is 47.23%, while at National Library of Indonesia is 21.89%. Pursuant to this research result is suggested to re-structure terms relationship on the authority National Library of Indonesia and integrate the catalogue and the authority database.

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.
