Judul: Uji Usability Dengan Metode Cognitive Walkthrough pada Situs Web IPB Connect.
Abstrak: Keterlibatan pengguna secara aktif dalam mengembangkan antarmuka situs web IPB Connect menjadi sangat penting. Salah satu cara mengevaluasi antarmuka situs web dengan melakukan uji usability. Penelitian ini dapat memberikan rekomendasi perbaikan antarmuka situs web IPB Connect agar menjadi lebih user friendly. Pengujian dilakukan dengan metode Cognitive Walkthrough. Hasil perhitungan pengujian yang dilakukan oleh 10 orang responden dengan memberikan tahapan skenario menghasilkan success rate 100% lalu pengujian dengan tidak memberikan tahapan skenario mencatat waktu tercepat 0:31:03 detik. Kemudian waktu terlama 0:33:04 detik, dan waktu rata-rata mencatat 0:32:44 detik. Lalu dibandingkan dengan pengujian yang dilakukan oleh developer dengan waktu total 0:11:07 detik. Efisiensi skenario tugas berdasarkan ukuran 2n yaitu waktu maksimum bagi responden. Nilai n adalah jumlah waktu pengerjaan bagi developer, sehingga nilai untuk responden harus maksimal 2 kali dari jumlah waktu developer. Dari hasil tersebut dapat disimpulkan bahwa antarmuka situs web IPB Connect perlu dilakukan perbaikan di sisi view layout karena belum memenuhi standar user friendly agar pengguna lebih nyaman saat menggunakan IPB Connect.

Judul: Pengujian Usability pada Ijah-Webserver dengan Menggunakan Metode Cognitive Walkthrough.
Abstrak: Indonesia Jamu Herbs Webserver (Ijah-Webserver) adalah perangkat lunak aplikasi berbasis web yang memberikan kemudahan untuk mendapatkan informasi konektivitas antara senyawa bioaktif dari suatu tanaman dengan protein. Ijah- Webserver selalu mengalami perkembangan. Pengembangan Ijah-Webserver perlu memperhatikan aspek usability. Pengujian usability bertujuan untuk menentukan apakah Ijah-Webserver bermanfaat, diterima pengguna dan bertahan lama dalam penggunaannya. Penelitian ini melakukan usability testing pada Ijah- Webserver dengan menggunakan metode Cognitive Walkthrough yaitu metode berbasis skenario tugas. Usability testing mencangkup dua komponen yaitu efektivitas dan efisiensi. Berdasarkan hasil analisis usability testing ditemukan hal-hal yang menyebabkan rendahnya usabilitas antarmuka Ijah-Webserver yaitu kurangnya informasi cara menggunakan Ijah-Webserver, penempatan menu/button yang kurang tepat dan keluaran yang masih sulit dibaca. Rekomendasi perbaikan antarmuka Ijah-Webserver berdasarkan hasil analisis yaitu menampilkan pedoman atau petunjuk cara menggunakan Ijah-Webserver, merubah letak menu/button agar mudah ditemukan pengguna dan merubah hasil keluaran serta format unduhan.

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
