Judul: OLAP operations and addition of aggregate functions in the food crops temporal data warehouse in Karo
Abstrak: Yearly data recorded in an organization would lead to accumulation of the data. Many organizations now already use data warehouse technology to obtain more structured information. Data warehouse could help them in making decisions by analyzing historical data, but changes in the process of recording object data such as split and merge, would complicate search in the data warehouse. Currently there's already a developed data warehouse with temporal approach to address issues such as split and merge. This study improves food crop temporal data warehouse in Karo by adding OLAP operations. Implementation of OLAP in multidimensional data would make data analysis in the data warehouse easier for the user. OLAP operations which will be developed in this temporal data warehouse is slicing, dicing, drill down, and roll up process, and also aggregate functions. Key words: Temporal Data Warehouse, OLAP Operations, Aggregate Function.

Judul: Pembuatan temporal data warehouse pada komoditi tanaman pangan dan hortikultura Kabupaten Karo, Sumatera Utara
Abstrak: Perkembangan teknologi yang semakin cepat dari hari ke hari ikut berimbas pada proses pengumpulan data, proses penyimpanan data bahkan proses penggudangan data. Perusahaan­pernsahaan maupun instansi menggunakan berbagai cara untuk melakukan proses penggudangan data dengan menggunakan data warehouse. Data warehouse merupakan salah satu metode yang dapat digunakan untuk proses penggudangan data dengan mengambil data historis yang memiliki struktur yang sama. Namun jika terjadi perubahan struktur pada data, misalnya proses pemisahan (split) data atau proses penggabungan (merge) data, maka data warehouse perlu dikembangkan lagi untuk menangani perubahan struktur yang ada. Penelitian ini melakukan perkembangan dari data warehouse dengan menerapkan pendekatan dengan aspek temporp/, sehingga data warehouse yang dihasilkan mampu untuk menangani setiap kasus yang berhubungan dengan perubahan struktur pada data, seperti split clan merge. Penelitian ini mengambil data tanaman pangan dan hortikultura kabupaten Karo, Provinsi Sumatera Utara dari tahun 2003 sampai tahun 2003. Komoditas yang terlibat adalah tanaman pangan dan hortikultura di kabupaten Karo. Ukuran yang diamati adalah produksi, luas tanam, dan luas panen.

Judul: Pengujian Virus Newcastle Disease Gen VII Isolat Lapang Sebagai Virus Standar Pada Uji Tantang Vaksin
Abstrak: This study was conducted to determine the standard of Newcastle disease virus Gene VII field isolate as a virus challenge to vaccine test. A virus suspension that has previously been tested by HA test then titrated with EID50 using 30 Specific Pathogen Free (SPF) of 10 day old chicken embryonated eggs. In addition, chicken lethal dose50 (CLD50) test were used to determine the virus titer that could cause 50% death of the chicken population. The CLD50 test was used 25 day-old-chickens (DOC) divided into 5 groups. The virus was diluted from 10-1 to 10-8. The 104 to 10-8 dilution of NDV was infected to every group of chicken via eyedrop and intranasal with 0.1 ml/chicken dosage. Haemagglutination test showed that the allantoic fluid were contain high titers of NDV is 512 HAU. The infective NDV that had been titrated by EID50 test showed the virus titers is 109 EID50/0.1 ml or 1010 EID50/ml and the virus titers of CLD50 test e.i 106.48 CLD50/0.1 ml or 107.48 CLD50/ml. These results can be concluded that the NDV Gene VII field isolates were most appropriate to be used as a standard virus to vaccine test
