Judul: Modul Extract, Transform, Load (ETL) untuk Data Warehouse Akademik Departemen Ilmu Komputer IPB Menggunakan Kettle
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 Pengamatan Cuaca Menggunakan Kettle.
Abstrak: Data warehouse merupakan teknologi yang dinilai dapat menangani permasalahan penumpukan data yang berukuran besar. Tahapan penting dalam pembangunan data warehouse adalah proses extract, transform, dan loading (ETL). ETL merupakan penghubung antara sumber data dengan data warehouse. Proses ETL secara manual dinilai tidak efektif dan efisien karena data yang cukup besar dan tersebar di berbagai sumber. Pada penelitian ini dilakukan perancangan dan implementasi modul ETL untuk data warehouse pengamatan cuaca yang dibuat dengan menggunakan perangkat lunak Kettle. Data yang digunakan penelitian ini adalah data pengamatan cuaca dari tahun 1986 hingga tahun 2016 yang diperoleh dari 170 stasiun cuaca di Indonesia, data lokasi stasiun cuaca dan data peta wilayah administratif Indonesia. Pengujian dilakukan dengan melakukan verifikasi dan validasi terhadap modul ETL yang dibangun. Penerapan modul ETL diharapkan dapat meningkatkan efisiensi sumber daya dan menekan biaya dalam implementasi 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
