    Penelitian ini bertujuan untuk mengetahui ada tidaknya pengaruh kemampuan diri, kesiapan kampus, dan awareness mahasiswa pada minat berkarir mahasiswa di bidang data science. Populasi penelitian ini merupakan seluruh mahasiswa Akuntansi Unika Soegijapranata yang masih aktif mengikuti perkuliahan per semester Ganjil tahun akademik 2021/2022. Pemilihan sampel menggunakan teknik simple random sampling dengan total sampel yang diperoleh berjumlah 272 responden. Pengumpulan data dilakukan melalui media online yakni Google Form. Hasil pengujian menunjukkan bahwa kemampuan diri berpengaruh pada minat berkarir mahasiswa, kesiapan kampus tidak berpengaruh pada minat berkarir mahasiswa, dan awareness mahasiswa berpengaruh pada minat berkarir mahasiswa

    Dynamic polarizability of rotating particles in electrorheological fluids

    A rotating particle in electrorheological (ER) fluid leads to a displacement of its polarization charges on the surface which relax towards the external applied field E0{\bf E}_0, resulting in a steady-state polarization at an angle with respect to E0{\bf E}_0. This dynamic effect has shown to affect the ER fluids properties dramatically. In this paper, we develop a dynamic effective medium theory (EMT) for a system containing rotating particles of finite volume fraction. This is a generalization of established EMT to account for the interactions between many rotating particles. While the theory is valid for three dimensions, the results in a special two dimensional configuration show that the system exhibits an off-diagonal polarization response, in addition to a diagonal polarization response, which resembles the classic Hall effect. The diagonal response monotonically decreases with an increasing rotational speed, whereas the off-diagonal response exhibits a maximum at a reduced rotational angular velocity ω0\omega_0 comparing to the case of isolated rotating particles. This implies a way of measurement on the interacting relaxation time. The dependencies of the diagonal and off-diagonal responses on various factors, such as ω0\omega_0, the volume fraction, and the dielectric contrast, are discussed.Comment: 6 pages, 4 figures, accepted to J.
