Abstrak: Extraction, transformation, and loading (ETL) are processes which have important role to determine data warehouse quality. ETL is bridging between data source and data warehouse. Activities such as cleaning, integration, and data loading at data were done in this process. Making ETL manually is inefficient, because data that will grow and data with different sources become problematic in data integration. This research performs ETL using special tools that are expected to simplified the ETL process and consistently of data output. ETL tool which used are Kettle, while designing a data warehouse using Pentaho Schema Workbench and result are visualized in OLAP in Mondrian to test the ETL process. The result in this research is a data warehouse having integrated and dynamic ETL.

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: Systematics of Desmos (Annonaceae) in Malesia
Abstrak: Desmos is a woody climbing genus of Annonaceae which has been widely used as traditional medicine in several countries such as China, Indo-China, Thailand, and Peninsular Malaysia to treat dysentery, vertigo, fever, and postpartum. Phylogenetic studies on Desmos showed a close relationship between Desmos and Dasymaschalon. They share similar moniliform monocarpic fruits, but their flowers are different. It has been debated among Annonaceae researchers whether both genera should be treated as the same or distinct genus. Therefore, investigation on the taxonomic delimitation of Desmos species and Dasymaschalon will be necessary. Plastid genome (plastome) identification, leaf epidermal section of Desmos species and Dasymaschalon species, a taxonomic revision of Desmos in Malesia using morphological data, the spatial distribution of Desmos species in Malesia, and morphological and genetic variation in Desmos chinensis population using ISSR marker were used to investigate taxonomic delimitation of Desmos. Plastome study of Desmos chinensis and Dasymaschalon dasymaschalum was carried out to determine the origin, evolution, phylogenomics, and identify marker candidates for Desmos and Dasymaschalon or with other genera in Annonaceae. We discovered that the plastome of Desmos chinensis was circular with the size of 167,677 bp (smaller than Dasymaschalon dasymaschalum), consist of 111 genes, including 78 protein-coding genes, 29 transfer RNAs, and 4 ribosomal RNAs. The plastome showed a typical quadripartite structure, i.e., large single copy (LSC), small single copy (SSC), and two inverted repeats (IRs). The plastome of Dasymaschalon dasymaschalum was 191,488 bp in length, which also exhibited a typical quadripartite structure (LSC, SSC, and two IRs). Desmos chinensis and Dasymaschalon dasymaschalum showed different copies of accD, ndhD, ndhF, rps18, and ycf2. Protein coding genes of rpoB, rpoC1, rbcL, matK, rpl32, infA, and rpl36 were identified based on nucleotide diversity, sequence variability, and parsimony-informative sites. The genes are defined as molecular marker candidates of plastome for phylogenetic, barcoding, and population genetic research. We predicted that Desmos chinensis and Dasymaschalon dasymaschalum separated at ca. 64 million years ago during the Paleocene. Leaf anatomical feature study was carried to support the taxonomic delimitation of interspecific Desmos and intergeneric of Desmos and Dasymaschalon. Leaf anatomy in the paradermal section of 20 taxa (12 species of Desmos, eight species of Dasymaschalon) have been carried out. According to the leaf epidermal section, Desmos and Dasymaschalon are two distinct genera mainly distinguished based on the anticlinal wall undulation of epidermal cells and supported by variation of the crystal type and size. The anticlinal wall undulation of Desmos was almost straight to slightly wavy and never sinuous; meanwhile, Dasymaschalon varies from almost straight to deeply sinusoid. The crystals of Desmos consist of rhombohedral, druse type A, and druse type B crystals, whereas Dasymaschalon has prism, druse type A, druse type B, and druse type C crystals. The recent taxonomic revision using the morphological data was mainly based on the examination of about 1374 specimens from BO, L, WAN, ANDA, SING, SAN, K, P, HUH herbaria. The Desmos species in Malesia consists of eight species: D. acutus, D. chinensis, D. chryseus, D. dunalii, D. pedunculosus, D. subbiglandulosus, two new records: D. lawii and D. macrocarpus, and one
