Judul: Dashboard OLAP pada Sistem Informasi Manajemen Kinerja IPB
Abstrak: Sistem Informasi Manajemen Kinerja (SIMAKER) adalah sistem informasi yang bertujuan untuk mengukur dan menganalisis kinerja di Institut Pertanian Bogor (IPB). Saat ini, pengukuran dan analisis kinerja masih menggunakan basis data transaksional. Padahal, basis data transaksional tidak tepat jika digunakan untuk pengukuran dan analisis. Untuk mengatasinya, diperlukan infrastruktur dan alat analisis untuk melakukan pengukuran dan analisis kinerja seperti data warehouse dan online analytical processing (OLAP). Saat ini, IPB telah memiliki data warehouse yang menyimpan data dari berbagai sistem sumber yang ada di IPB. Namun, data warehouse tersebut belum dimanfaatkan untuk melakukan analisis data sehingga penelitian ini bertujuan untuk mengembangkan dashboard OLAP untuk menganalisis data pada SIMAKER. Model data multidimensional pada OLAP mampu menganalisis data yang berukuran besar secara cepat, dinamis dan intuitif. Hasil analisis OLAP ditampilkan melalui dashboard menggunakan Microsoft PowerBI. Penelitian ini berhasil mengembangkan dashboard yang menampilkan informasi yang dibutuhkan SIMAKER dan mengimplementasikan operasi-operasi OLAP seperti drill-down, roll-up, slice dan dice.

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.
