Judul: Pembangunan Data Warehouse dan Aplikasi OLAP  pada Data Akademik Fakultas  Matematika dan Ilmu Pengetahuan Alam IPB
Abstrak: Informasi mengenai nilai akademik dan perkembangan Indeks Prestasi Kumulatif (IPK) penting bagi Dekan, ketua departemen, dan bagian akademik Fakultas Matematika dan Ilmu Pengetahuan Alam – IPB untuk meningkatkan kualitas pengajaran dan kemahasiswaan. Proses analisis data nilai akademik masih dilakukan secara manual, yaitu dengan mengakses tabel data yang terhubung. Prosesnya memakan waktu lama karena masih menjalankan query secara manual ke setiap tabel data. Teknologi data warehouse dan On-Line Analytical Processing (OLAP) dapat mempercepat pemrosesan dan analisis data akademik. Tujuan dari penelitian ini adalah membangun data warehouse dan aplikasi OLAP berbasis web untuk data akademik S1 Fakultas Matematika dan Ilmu Pengetahuan Alam – IPB dengan menggunakan Mondrian 3.1.6 sebagai server OLAP. Tahapan penelitiannya adalah: proses persiapan data, pembersihan data, integrasi dan transformasi data, dan implementasi pengoperasian OLAP. Gudang data menggunakan skema galaksi. Penelitian ini menghasilkan enam dimensi (waktu, jenis penerimaan, jenis kelamin, tahun akademik, jurusan, kota asal, dan jurusan) dan sebuah fakta (fakta_akademik). Pembuatan data warehouse dan aplikasi OLAP untuk data akademik di FMIPA menghasilkan satu kubus data yang disebut kubus data akademik. Kubus data dapat divisualisasikan secara tepat, cepat, dan akurat dalam tiga tata letak berbeda, yaitu diagram batang, diagram garis, dan diagram lingkaran menggunakan Mondrian 3.1.6. Operasi OLAP yang dilakukan adalah roll-up,drill-down, dice dan slice.

Judul: Pembangunan Data Warehouse dan Aplikasi OLAP untuk Memantau Prestasi Mahasiswa Program Studi S1 Ilmu Komputer IPB
Abstrak: Many factors influence Department of Computer Science students achievement. The factors such as GPA, student supervisor, status of study, and sum of competition achievement. These factors can be analyzed with the data processing to find the information patterns that can increase the student’s achievement. The academic and non academic’s data of Program Study S1 Computer Science student spread in some location. This data make long running queries performance that complicated the analysis process. This research produce data warehouse which is integrated to online analytical processing (OLAP) that can represents data with graph and crosstab table. The OLAP server used in this research is Jedox 5.1. The data used are the academic and non academic’s data of IPB Computer Science students entry’s year 2006 to 2009. The steps being taken include analysis, design, preprocessing, and concluded with the implementation of data warehouse and OLAP operations. The data warehouse schema is created using the galaxy scheme. The result of research are three cubes (Research, Academic, and Achievement).

Judul: Posisi Filogenetik Kura-Kura Carettochelys Insculpta  (Reptillia: Testudinata)
Abstrak: Carettochelys insculpta is an endemic freshwater turtle of southern Papua and northern Australia. Phylogenetic position of this turtle is remain unresolved until now. Most of the research conducted show close relationships of C. insculpta and members of Trionychidae family. However, some of the research show distance between C. insculpta and members of Trionychidae family. This research is conducted to analyze phylogenetic relationship between C. insculpta and other members of Testudinata using 12S rRNA, 16S rRNA, and both gene as markers. DNA samples were obtained from three different organisms of C. insculpta. Two species used as outgroups were Alligator mississippiensis and Iguana iguana. Phylogenetic analysis was carried out using Neighbor-Joining method with Felsenstein 1981 (F81) modeltest. A polytomy tree of Testudinata was produced by using 12S rRNA gene. However, analysis using 16S rRNA and both genes as markers confirmed that C. insculpta was located between the Chelonidae and the Trionychidae family.
