Abstract

Online tutorials as a form of student services is expected to contribute to the success of student learning. This article is written based on the research on the online tutorial activities of Strategic Management Courses (EKMA4414) and student learning outcomes in the registration period of 2009.1 at UPBJJ-UT Batam. Data were collected using purposive sampling of 167 students registered in online tutorial. Results were analyzed descriptively. The results showed that the initiation of online tutorials materials of strategic management course were generally in line with course objectives. However, the presentation is said to be less systematically delivered by most students. This causes some students to not actively engaged in the tutorial and do the exercises and tasks. However, for students who are actively following tutorial by participating in discussion and exercises, their activities contribute to the final grade. Tutorial online sebagai salah satu bentuk layanan mahasiswa diharapkan memberiukan kontribusi terhadap keberhasilan belajar mahasiswa yang ditunjukkan oleh nilai akhir. Artikel ini disusun berdasarkan hasil penelitian tentang kegiatan tuton mata kuliah Manajemen Strategi (EKMA4414) dan hasil belajar mahasiswa masa registrasi 2009.1 di UPBJJ-UT Batam. Data dikumpulkan secara purposive dan analisa yang digunakan adalah deskriptif kuantitatif. Sampel pada penelitian ini adalah sekelompok mahasiswa berjumlah 167 orang yang melakukan registrasi tutorial online. Hasil menunjukkan bahwa materi inisiasi tutorial online Manajemen Strategi pada umumnya dinyatakan sangat sesuai dengan tujuan pembelajaran. Namun demikian sistematika penyajiannya masih dikatakan kurang baik oleh sebagian mahasiswa. Hal ini menyebabkan tidak semua mahasiswa aktif mengikuti tuton dan mengerjakan tugas-tugasnya. Namun demikian bagi mahasiswa yang aktif mengikuti tuton, berdiskusi dan mengerjakan tugas, terlihat bahwa keaktifan mereka berkontribusi dalam memperoleh nilai akhir mata kuliah yang cukup baik

Abstract

The research computed the energy levels and radial wave functions of the  Hydrogen Atom. The method used for computation was FEM (finite element method). Using the variational method approach, FEM was applied to the action integral of  Schrödinger equation. This lead to the eigenvalue equation in the form of  global matrix equation. The results of computation were depended on boundary of the action integral of Schrödinger equation and number of elements. For boundary 0 - 100a0 and 100 elements,  they were the realistic and best choice of computation to the closed  analytic results. The computation of first five energy levels resulted E1 = -0.99917211 R∞, E2 = -0.24984445 R∞, E3 = -0.11105532 R∞,           E4 = -0.06247405 R∞ and  E5 = -0.03998598 R∞ where 1 R∞ = 13.6 eV. They had relative error under 0.1% to the analytic results.

Abstract

The Kampus Merdeka lately becomes the center of attention for the education circle in Indonesia. The government via Indonesian Minister of education and culture believed that the Kampus Merdeka as an effort to freedom for the education system more supportive of students and lecturers in achieving quality learning meaningful to face the disruption of the current era. This paper presents the authors' views on "Kampus Merdeka" which was promoted by the Indonesian government. Also, the authors will underline the concept of "Kampus Merdeka" in accordance with Paulo Freire's critical pedagogy. From our point of view, we give a position this concept is developed based on the thinking of Paulo Freire. As we know, Freire's educational model offered a model of education for freedom. In this case, the term ‘freedom’ means a transformation in a real system that is competitively related and complex.

Abstract

Airfoil is a cross section from air plane wings can affect aerodynamic performance to lift force (FL). The lift force generated by airfoil has different values due to several external and internal factors, including angle of attack, flow rate and camber. To find the lift force of airfoils with different cambers and variations angle of attack and then flow rate can use computational fluid dynamics simulation. Computational fluid dynamics is simulation on a computer that can complete systems for fluid, heat transfer and other physical processes. This research using computational fluid dynamics simulation performed by SolidWorks, with NACA airfoil type which has different camber NACA 0012, NACA 4612 and NACA 6612. The angle of attack used in research was 0o, 4o, 8o, 12o, 16o and 20o. Flow rate used in research was 20m/s, 40 m/s, 60 m/s, 80 m/s and 100 m/s. From this research will be the bigger camber can produce a greater force lift. In addition, the greater airfoil flow rate can produce a greater force lift. This research also that the connection between force lift with coefficient lift (CL) is nonlinear quadratic form.
