Judul: Otomasi Manajemen Instalasi dan Konfigurasi Komputer Lab Ilmu Komputer IPB dengan Chef
Abstrak: Laboratorium Komputer di Departemen Ilmu Komputer Institut Pertanian Bogor memiliki banyak komputer dan tidak sedikit aplikasi yang dibutuhkan untuk aktivitas praktikum di laboratorium tersebut. Setiap akhir semester dilakukan instalasi ulang dengan menggunakan cara yang belum sepenuhnya otomatis. Instalasi dan konfigurasi tidak efektif apabila masih menggunakan proses manual, yaitu instalasi aplikasi dilakukan satu per satu di setiap komputer. Penelitian ini mengimplementasikan manajemen instalasi dan konfigurasi menggunakan Chef. Tahapan dari penelitian ini meliputi identifikasi masalah, identifikasi kebutuhan, implementasi, pengujian di mesin virtual, dan analisis hasil dan kinerja. Hasil dari penelitian ini menunjukkan Chef berhasil melakukan otomasi instalasi dan konfigurasi komputer lab Ilmu Komputer IPB. Namun, kinerja Chef lebih lambat sekitar 3% dibandingkan Shellscript pada 4 klien.

Judul: Otomasi Instalasi dan Konfigurasi pada Komputer Lab Ilmu Komputer IPB dengan SaltStack
Abstrak: Manajemen Instalasi dan konfigurasi laboratorium Ilmu Komputer IPB selama ini menggunakan mirroring diska dan shell script. Hal ini masih dinilai kurang efektif dan efisien. Penelitian ini melakukan manajemen instalasi dan konfigurasi menggunakan SaltStack. Metode yang digunakan ialah identifikasi kebutuhan perangkat lunak lab, penerapan otomasi dengan SaltStack, validasi hasil instalasi, dan konfigurasi, dan pengujian kinerja pada mesin virtual. Pengujian kinerja berupa pengukuran waktu instalasi pada shell script (semi-otomatis) dan SaltStack dengan jumlah VM klien 1, 2, 3 dan 4. SaltStack berhasil menginstal perangkat lunak pada 1, 2, 3, dan 4 VM klien sekaligus. Berdasarkan hasil pengujian pada 4 VM klien kinerja SaltStack hanya lebih cepat 10% daripada shell script. Setiap penambahan 1 komputer klien mempengaruhi waktu instalasi pada shell script sekitar 17 menit dan 15 menit pada SaltStack. SaltStack dapat menggantikan shell script dalam manajemen instalasi dan konfigurasi laboratorium komputer Ilmu Komputer IPB. Hal ini karena SaltStack menyediakan log instalasi yang akan mempermudah jika terjadi masalah.

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
