Judul: Pengembangan data warehouse program tracking stasiun TV di Indonesia
Abstrak: Stasiun TV berusaha untuk meningkatkan rating, sharc dan jumlah penonton dengan memperhatikan biaya produksi yang dikeluarkan. Data stasiun TV yang berisi rating, share, jumlah penonton, dan biaya produksi adalah data program tracking. Data program tracking diterima stasiun TV dari perusahaan penyedia data setiap minggu. Data acara tersebut menjadi acuan dalam menganalisis potensi sebuah acara. Untuk mernudahkan proses analisis, maka dibuat data warehozise yang mempakan tempat penyimpanan data yang terintegrasi, multidimenri, dan menampilkan data dalam suatu bentuk yang diharapkan akan memudahkan proses analisis dalarn pembuatan keputusan.Hasii dari penelitian ini adalah suatu data warehozise untuk data program tracking dan suatu OLAP browser yang mempunyai fasilitas untuk menambah data yang datang setiap minggunya dan visualisasi berupa tabel pivot dan diagram batang dalam menampilkan data numerik dan tabel relasional untuk menampilkan data kategorik. Visualisasi ini dibuat untuk rnempermudah pengguna dalam melihat data dalam proses analisis.Kata Kunci : Data warehozise, Multidimensi, Online Analytical Processing (OLAP), Skema bintang.

Judul: Pembangunan spatial data Warehouse berbasis Web untuk persebaran hotspot di wilayah Indonesia
Abstrak: A data warehouse is a repository of data organized following a multidimensional model in order to be analyzed by On-Line Analitycal Processing (OLAP) applications. Data warehouse and OLAP systems help to interactively analyze huge volumes of data. Spatial data warehouse refers to integration of spatial data in multidimensional data model of which the analyses result is the basic of strategic decisions. In order to include spatial information as a result of decision-making process, we developed data warehouse intended to explore data related to space i.e. spatial data. This research develops spatial data warehouse and spatial OLAP for hotspot distribution in Indonesia using Geomondrian. Geomondrian is a web-based spatial OLAP integrated solution supporting spatial dimensions and measures, and providing interactive pivot tables and diagrams displays. Geomondrian as spatial OLAP server can execute OLAP operations with spatial data including roll-up, drill-down, dice, slice, and pivoting.

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.
