Judul: Development of Asset Information System Using  QR Code with Prototyping Methode
Abstrak: Institut Pertanian Bogor (IPB) merupakan salah satu perguruan tinggi negeri terbesar di Indonesia memiliki kebijakan dalam tata kelola aset dan inventaris Barang Milik Negara (BMN) maupun Barang Milik IPB (BMI). Ditemukannya beberapa aset atau barang milik negara yang rusak, hilang maupun berpindahpindah sehingga diperlukan suatu sistem yang dapat melalukan pelacakan (tracking) aset tersebut dalam melakukan pengelolaan terhadap aset serta identitas yang dapat menjadi sebuah ciri terhadap kepemilikan barang. Pengembangan sistem pada penelitian ini menggunakan metode prototyping sebanyak dua iterasi. Tujuan dari penelitian ini adalah melakukan pencatatan aset pada kantor DSITD, memberikan informasi terkait dengan aset secara lengkap. Pengembangan sistem berbasis web telah dilakukan menggunakan framework Laravel 8 dengan API dari sistem I-Promise untuk mendapatkan data barang. Sistem yang telah dikembangkan digunakan oleh pengelola aset DSITD IPB. Keluaran dari pengembangan sistem pada penelitian ini adalah menerapkan QR Code untuk dicetak dalam bentuk stiker atau label yang berfungsi sebagai identitas terhadap aset barang. Pengujian sistem ini telah dilakukan dengan menggunakan metode blackbox dengan hasil sistem dapat berjalan dengan baik dan benar sesuai dengan kebutuhan utama pengguna dan sistem.

Judul: Pembangunan sistem informasi manajemen inventarisasi barang milik Negara dengan metode agile unified process (AUP)
Abstrak: Government assets inventory in the Secretariat of the Vice-President office is still carried out manually. Assets are recorded into the main book only for new assets or goods, however unused assets have not been well recorded. This condition raises several problems, such as time consuming for assets recording process, difficulty in data collection of inventory items, difficulty in goods inventory in the warehouse, unidentified asssets condition (damaged items) for the elimination of the goods and the lack of accurate data on the number of items in the warehouse. Therefore, this study is carried out to design a management information system of government assets inventory in the Secretariat of the Vice President office. The management information system development consists of four stages: inception, elaboration, construction and transition stages. Development of a web-based system is conducted by using PHP programming language. A black-box testing technique is used to test the system. The developed system is expected to assist in conducting a better and well organized government assets inventory process. Government assests inventory management information system will also be more user-friendly especially for inventory.

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.
