Judul: Pengembangan sistem repositori pengetahuan berbasis ontologi dan jaringan semantik studi kasus pada perpustakaan Unika ST. Thomas Medan
Abstrak: Peran signifikan perguruan tinggi dalam pembangunan bangsa terdapat pada konsep "Tri Dharma Perguruan Tinggi", yang meliputi pendidikan, penelitian, dan pengabdian pada masyarakat. Dari ketiga dharma perguruan tinggi, fungsi penelitian adalah fungsi yang belum terlaksana dengan baik. Data tahun 2008 menunjukan bahwa dosen yang melakukan penelitian di Indonesia masih di bawah 10% (Jalal, 2008).

Judul: Studi Kelayakan Pengembangan Sistem Perpustakaan Digital Berbasis Web Di Perpustakaan Sekolah Tinggi Perikanan (STP) Jurusan Penyuluhan Perikanan (Jurluhkan) Bogor
Abstrak: Pesatnya kemajuan TI, ledakan informasi, tuntutan pengguna dan pemberdayaan sumberdaya pengetahuan serta peningkatan daya saing layanan harus mampu diimbangi dan diantisipasi pesatnya kemajuan perpustakaan sebagai salah satu information provider dan knowledge repository. Salah satu strateginya dengan mengembangkan perpustakaan digital berbasis web. Sejalan dengan itu perpustakaan STP Jurluhkan Bogor dalam mendukung visi dan misi lembaga induknya bertugas memberikan pelayanan terbaik dalam penyediaan, penyimpanan dan pelayanan informasi, serta sebagai mitra dosen dan taruna (mahasiswa) berkepentingan untuk dapat memberdayakan sumber pengetahuan yang dimiliki (knowledge resources). Untuk itu perlu dilakukan studi kelayakan (feasibility study) pengembangan sistem perpustakaan digital berbasis web di perpustakaan STP Jurluhkan Bogor. Pengembangan perpustakaan digital berbasis web tersebut perlu didukung oleh elemen dasar (basic elements) perpustakaan digital yang ideal, yaitu: SDM, koleksi, infrastruktur, SOP, manajemen dan anggaran yang berpedoman pada grand design perpustakaan digital Pustaka Bogor. Karena itu perlu dikaji kondisi obyektif elemen dasar Perpustakaan STP dan membandingkannya dengan kondisi elemen dasar ideal perpustakaan digital berbasis web. Tujuan penelitian untuk mengetahui seberapa besar tingkat kelayakan elemen dasar yang dimiliki dan memformulasikan saran dan rekomendasi mengenai kelayakan elemen dasar yang harus dimiliki oleh Perpustakaan STP Jurluhkan Bogor. Penelitian dilaksanakan di perpustakaan STP Jurluhkan Bogor dan Pustaka Bogor.

Judul: Bioelectricity Production from Citrobacter freundii GBH253 and Chlorella pyrenoidosa on Microbial Fuel Cell Anode with Different Carbon Sources
Abstrak: Microbial Fuel Cell (MFC) development has significantly increased from various aspects to get higher and more stable electricity. Developing MFC on microorganism aspect is very important because it plays a crucial role in the MFC system. C. freundii GBH253 is one of the potential exoelectrogen bacterium that could be developed for the MFC system. Integrating C. freundii GBH253 and electricity-producing microalgae, such as C. pyrenoidosa, in the anode of MFC could get more stable and higher electricity. In this study, C. freundii GBH253 and C. pyrenoidosa were coupled to produce electricity from different substrates. C. freundii GBH253 and C. pyrenoidosa were tested on three different media types before being tested on MFC. They were also examined for the co-cultivation test to determine the symbiotic relationship between the two microorganisms. The MFC test was conducted using the Randomized Block Design Factorial and the Tukey test to see significant differences from each treatment. The parameters observed in this study were voltage, power density, Chemical Oxygen Demand (COD), Coulombic Efficiency (CE), pH, and volatile fatty acid (VFA). C. freundii GBH253 cannot grow on microalgae medium, while C. pyrenoidosa could grow on bacterial medium and a mixture of bacterium and microalgae media. The bacterium gained benefit from co-culture with microalgae. In the MFC test, electricity was generated in all treatments, which bacterium + microalgae with acetate treatment could generate power density up to 211,97 mW/m2 and the most stable compared to others. Production of electricity in bacterium-microalgae combination dominated by the bacterium; hence, microalgae still help bacterium by producing electricity and raised the COD value. The pH value of all treatments was higher than the initial pH. Acetate and phenol were VFA produced in all treatments, whereas butyric acid and propionic acid were found in some treatments. Pearson correlation showed that some VFA highly correlated with power density.
