Judul: Pengembangan IPB Reality Browser Menggunakan Usability Engineering Lifecycle
Abstrak: Digital media enables the process of information sharing services. One of these information services is application of augmented reality (AR). AR application is a practical application to obtain information through interactive media and provide a lot of interesting experiences for the users by displaying digital objects that are combined with the state of the surrounding environment. AR application can be accessed by utilizing digital media such as computers, tablet PCs, and mobile phone. The main idea of this research was to create a prototype for user interface application which includes visibility, usability, learnability, and user experience based on the usability engineering lifecycle. The prototype was tested according to the usability goals that has been formulated, and it was found that the prototype result in good learnability, user retention over time, and error rate. Learnability is shown by the successful completion of all given task, where as user retention over time is shown by the reduction of time required by the tester in completing the task. The prototype’s small error rate indicated that the prototype is usable.

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: Mitochondrial DNA Gene Organization and Phylogenetic Relationship of Naja siamensis
Abstrak: Naja siamensis is one of Asiatic cobra in the Family of Elapidae, known as a cryptic snake. It has many morphological variations that lead to misidentification. Misidentification can cause the wrong concept in developing antivenom types due to high snakebite cases occur in Thailand. Thus, an accurate species identification using a molecular approach is crucially required. Mitochondrial DNA has been used widely in snake molecular studies. These studies were aimed to determine the arrangement of the N. siamensis partial mitochondrial genes using reptile-oriented primers and to reveal the phylogenetic relationship among other species of Asian cobra. DNA extraction was carried out based on the standard DNA salting-out protocol and was conducted by bioinformatics analysis using BLASTn and MEGA 6 software. Gene annotation was performed against N. kaouthia complete genome. A total of 3121 bp of N. siamensis mtDNA genes were sequenced consisting of partial of six regions: 16S rRNA, ND1, tRNA-Ile, CRII region, tRNA-Leu, tRNA-Gln, and COI genes. The mtDNA gene organization of N. siamensis was predicted to has a similar pattern with the common Elapidae mtDNA gene organization. This study showed that there is a monophyletic form in Naja genus and N. kaouthia is the closest species with N. siamensis based on partial 16S rRNA and ND1 gene.
