Judul: Evaluation of Comprehensive Knowledge Archive  Network (CKAN) as a Research Data Repository of IPB Computer Science  Department
Abstrak: Aspek kunci dari manajemen data tidak hanya melibatkan penyediaan artikel, tetapi juga data atau materi, yang digunakan untuk melakukan penelitian tersebut. Sebagai salah satu bagian dari salah satu perguruan tinggi di Indonesia, Departemen Ilmu Komputer IPB berencana membangun repositori data penelitian, sebuah ruang penyimpanan bagi sivitas akademika untuk menyimpan kumpulan data yang terkait dengan penelitian mereka. Platform yang dipilih sebagai dasar dalam penelitian ini adalah Comprehensive Knowledge Archive Network (CKAN). CKAN adalah sistem manajemen data yang digunakan untuk mempublikasikan, berbagi, dan menggunakan kembali data. Dalam penelitian ini, peneliti menggunakan Design Science Research Method (DSRM) untuk menganalisis sejauh mana CKAN dapat berperan sebagai repositori data penelitian yang efektif. Analisis dilakukan dengan cara mengevaluasi kemampuan CKAN dalam memenuhi kebutuhan dan praktik manajemen data penelitian (FAIR principles). Kebutuhan yang dianalisis dikelompokkan berdasarkan tema, yaitu search and discovery, access, user interface dan other special features. Selain itu, dalam penelitian ini, peneliti juga mendesain berbagai jenis peran pengguna, metadata yang digunakan untuk menjelaskan data penelitian, serta mengkustomisasi tampilan platform. Ditemukan bahwa CKAN menawarkan fitur-fitur yang mumpuni dalam memenuhi kebutuhan manajemen data penelitian dan membantu peneliti dalam menemukan kembali data penelitian (findable), mengakses data tersebut (accessible), berbagi data (interoperable), dan menjaga keutuhan data sehingga dapat digunakan kembali (reuseable). Dari hasil temuan ini, dapat disimpulkan bahwa CKAN dapat digunakan sebagai repositori data penelitian di Departemen Ilmu Komputer IPB., The key aspect of data management involves not only providing articles but also the data or materials used for conducting the research. As a part of one of the universities in Indonesia, IPB Department of Computer Science plans to build a research data repository, a storage space for the academic community to store their research-related datasets. The chosen platform as the basis for this research is the Comprehensive Knowledge Archive Network (CKAN). CKAN is a data management system used for publishing, sharing, and reusing data. In this research, the researchers utilize the Design Science Research Method (DSRM) to analyze the extent to which CKAN can serve as an effective research data repository. The analysis is conducted by evaluating CKAN's capabilities in meeting the needs and practices of research data management (FAIR principles). The needs that were analyzed were grouped by theme, namely search and discovery, access, user interface and other special features. In addition, in this study, the researcher also designed different types of user roles, metadata used to explain the research data, and customized the appearance of the platform. It was found that CKAN offers robust features for meeting the requirements of research data management and helping researchers in finding back research data (findable), accessing the data (accessible), sharing data (interoperable), and maintaining data integrity so that it can be reused (reuseable). Based on these findings, it can be concluded that CKAN can be used as a research data repository at IPB Department of Computer Science.

Judul: Kajian User Experience pada Repositori Institusi Institut Pertanian Bogor
Abstrak: Institutional Repositories adalah platform pengelolaan asset pengetahuan untuk membantu institusi mengatur ruang penyimpanan yang berpusat dengan tujuan mengoleksi, mengatur, menampilkan, melestarikan dan menyebarkan artefak pengetahuan secara sistematis. Repositori IPB merupakan salah satu repositori kampus terbaik di Indonesia. Pengembangan Repositori IPB sebelumnya hanya memerhatikan dari segi fungsionalitas, sehingga masih banyak beberapa task dan konten yang dianggap membingungkan pengunjung dalam mencari suatu dokumen pada Repositori IPB. Penelitian ini berfokus pada pengembangan Repositori IPB yang memerhatikan aspek user experience (UX) menggunakan metode five plane user experience elements. Metode tersebut memiliki lima lapisan yang memiliki keterkaitan antar lapisannya. Tahap pengembangan dilakukan dari lapisan bawah menuju lapisan atas, meliputi lapisan strategy plane, scope plane, structure plane, skeleton plane dan surface plane, Setelah penelitian ini diharapkan Repositori IPB bisa mendapatkan respon yang baik dari admin dan pengunjung dengan meningkatkan layanan yang memerhatikan UX sehingga branding dan pengunjung Repositori IPB bisa terus meningkat., Institutional Repositories is a knowledge asset management platform to help institutions organize centered storage space with the purpose of collecting, organizing, displaying, preserving and disseminating knowledge artifacts in a systematic. Repository IPB is one of the best institutional repositories in Indonesia. Development of IPB Repository previously only noticed in terms of functionality, so many multiple tasks and content considered to confuse the visitor in finding a document on IPB Repository. This research will be focusing in aspect of user experience (UX) using five planes user experience elements to development IPB Repository. The method has five layers that have linkages between the layers. The development phase is done from the bottom layer to the upper layer, includes layer strategy plane, scope plane, structure plane, skeleton plane and surface plane. After this research will expect Repository IPB can get a good response from the admin and visitors by improving services noticed UX so that branding and visitors Repository IPB increase significantly.

Judul: Hamiltonian formulation for linear waves motion in two layers fluid
Abstrak: The surface wave could be considered as a wave that separates two fluids, namely water and air. Based on this assumption, it is introduced the interfacial wave, a wave between two layers of fluid with different density. The formulation of interfacial waves motion begins with deriving the base equation of irrotational ideal fluid. Furthermore, according to irrotational fluid assumption, the base equation can be stated in velocity potential. In this derivation, the fluids domain is assumed to be restricted by rigid lid boundary conditions, both at the upper and lower limit. Therefore, the interfacial waves motion can be explained in a hamiltonian formulation. In the hamiltonian formulation, total energy is defined as the sum of kinetic and potential energy. The hamiltonian system is obtained from reduction of kinetic energy by using the Dirichlet Neumann Operator. The resulted kinetic energy equation is nonlinear. Therefore, this form is linearized by first part of the Taylor expansion. This linearization gives a dispersion relation of linear wave. Based on this dispersion relation, the phase speed of the linear wave depends on the density ratio of the two layers fluid.
