Judul: Rekayasa kebergunaan pada sistem informasi kehumasan IPB
Abstrak: This research proposes the dissemination of information about IPB to users who are on campus location. It also aims to build an information system that applies usability methods during system development so it can build a user-friendly and also easy–to-learn system. This information system will be installed into touch screen that will make users able to interact with system directly. Today‟s touch screens are often durable and robust and work well in environments where it will be exposed to wear. Another advantage is that touch screens are intuitive to use. However, good and rich content is not enough to make users explore it. The content has to be easily accessible and presented in a usable and experiential way. Based on the analysis of Computer System Usability Questionnaire (CSUQ), the development of Sistem Informasi Kehumasan IPB managed to perform a well usability. This is shown by the value of overall satisfaction (OVERALL) = 5.48, and obtained a value for each attribute, the system usefullness (SYSUSE) = 5.69, information quality (INFOQUAL) = 5.39, and interface quality (INTQUAL) = 5.20 on a 7 point-scale.

Judul: Analysis of Satisfaction Level and Net Benefit IPB  Undergraduate Students towards the Use IPB Mobile for Student Application
Abstrak: IPB University melakukan penerapan sistem informasi manajemen berbasis mobile melalui aplikasi IPB Mobile for Student untuk mendekatkan inovasi teknologi serta mewujudkan transformasi menjadi digital campus. Penelitian ini bertujuan untuk menganalisis persepsi kualitas, tingkat kepuasan dan net benefit yang dirasakan mahasiswa S1 IPB terhadap aplikasi IPB Mobile for Student. Penelitian ini merupakan penelitian kuantitatif dengan menggunakan desain eksplanatori. Penelitian ini dilakukan pada mahasiswa IPB dengan menggunakan teknik voluntary sampling sehingga didapatkan responden sebanyak 306 orang. Data dikumpulkan melalui alat bantu berupa kuesioner yang disebarkan secara online menggunakan google form. Data yang diperoleh diolah menggunakan Microsoft Excel, SPSS versi 25, dan SEM-LISREL 8.80. Hasil uji pengaruh menunjukkan adanya pengaruh positif dan signifikan pada persepsi kualitas terhadap kepuasan pengguna dan kepuasan pengguna berpengaruh positif signifikan terhadap net benefit. Saran yang bisa diberikan adalah pengguna diharapkan memberikan masukan mengenai kekurangan pada aplikasi sehingga IPB University sebagai pengembang aplikasi dapat meningkatkan kualitas pada aplikasi IPBMfs., IPB University implements a mobile-based management information system through the IPB Mobile for Student application to bring technological innovation closer and realize the transformation into a digital campus. This study aims to analyze the perceived quality, level of satisfaction and net benefits felt by IPB undergraduate students on the IPB Mobile for Student application. This research is a quantitative research using an explanatory design. This research was conducted on IPB students using voluntary sampling technique so that 306 respondents were obtained. Data were collected through a tool in the form of a questionnaire distributed online using a google form. The data obtained were processed using Microsoft Excel, SPSS version 25, and SEM-LISREL 8.80. The results of the influence test show that there is a positive and significant effect on perceived quality on user satisfaction and user satisfaction has a significant positive effect on net benefits. Suggestions that can be given are that users are expected to provide input regarding deficiencies in the application so that IPB University as an application developer can improve the quality of the IPBMfs application.

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.
