Judul: Pengembangan Modul Extract, Transform, Load Data Warehouse Hasil Komoditas Pertanian Indonesia Menggunakan Talend
Abstrak: Kementerian Pertanian Indonesia menghimpun data hasil komoditas pertanian Indonesia dalam fail yang tidak saling terintegrasi. Solusi terbaik untuk melakukan integrasi data tersebut adalah data warehouse dengan proses extract, transform, load (ETL). Penelitian ini membangun ETL data warehouse hasil komoditas pertanian Indonesia yang memungkinkan praproses dan pembersihan data lebih cepat sebelum dimuat ke data warehouse. Pembangunan ETL diawali dengan merancang data warehouse menggunakan skema bintang dan merancang pemodelan ETL untuk melakukan transformasi. Transformasi dilakukan dengan membagi fail menjadi header dan body file. Implementasi model transformasi dilakukan menggunakan tool Talend. Hasil pengujian transformasi menunjukkan bahwa proses ETL berjalan dengan baik. Pengujian nilai menunjukkan bahwa nilai keluaran pada DBMS dan operasi OLAP menghasilkan nilai yang sama dengan nilai masukan yang berasal dari fail masukan.

Judul: Modul Extract, Transform, Dan Load Untuk Data Warehouse Tanaman Hortikultura Menggunakan Kettle
Abstrak: Kualitas data, kompleksitas sumber data, hubungan dalam data, logging, kepakaran internal, dukungan, ruang penyimpanan dan penjadwalan merupakan faktor-faktor yang mempengaruhi kualitas data warehouse. Proses extraction, transformation, dan loading (ETL) merupakan penghubung antara sumber data dan data warehouse yang bertujuan untuk meningkatkan kualitas data warehouse. Proses ETL pada data berukuran besar jika dilakukan secara manual merupakan cara yang tidak efisien karena variasi data dari sumber data yang berbeda-beda akan membutuhkan waktu yang lama. Efisiensi waktu, sumber daya, dan biaya dalam implementasi data warehouse membutuhkan tool yang dapat melakukan proses ETL secara otomatis. Penelitian ini membuat modul ETL untuk data warehouse tanaman hortikultura dengan menggunakan Kettle. Data yang digunakan dalam penelitian ini adalah data tanaman hortikultura di Indonesia dari tahun 1960 sampai tahun 2014. Hasil penelitian ini berupa modul ETL berupa fail transformation dan job serta data warehouse tanaman hortikultura. Penelitian ini melakukan 2 pengujian yaitu pengujian ETL dan pengujian data warehouse.

Judul: Morphofunction changes of gonadal and mandibular glands of the cave swiflets (Collocalia linchi) during nesting and reproductive period
Abstrak: The present study aimed to study the morphological and histochemical changes and possible correlation between the gonads and mandibular glands of the cave swiflets (Collocalia linchi) during reproductive and nesting period. A total of seventy two adult birds were used in this study. The birds, three males and three females, were collected each month during a period of one year. After being sacrificed, samples of gonads and mandibular salivary glands were taken out and processed routinely for light microscopy. The present result showed that the gonads were active during the period of February - June. In the testis, the size of the testicle were similar throughout the year, but the testis had different color according to month. The testis in June - January were black in color, and were white and black in February, March, May and were all white in April. The size and structure of the ovaries were also increase towards February - May. Therefore the period of February - June was regarded as reproductive period of the cave swiftlet. The size and structure of mandibular glands were also clearly increased and the glands were more active during the nesting and reproductive period. Histochemically, the bindings of some lectins in the gonad and mandibular glands were also increase in the number of reactive cells and in the intensities of the positive reactions during the nesting and reproductive period, suggested that certain carbohydrates were involved and may play important roles in the reproductive function of the cave swiftlet. The present result showed that there were clear signs on the functional and structural changes of the gonads and mandibular glands of the cave swiftlets during the active nesting and reproductive period, suggested a possible regulatory mechanism of the mandibular gland through gonadal hormones pathway.
