Judul: Model Optimasi Jadwal Ujian Dan Implementasinya Pada Universitas Terbuka
Abstrak: Universitas Terbuka (UT) merupakan perguruan tinggi negeri yang menerapkan sistem pendidikan terbuka dan jarak jauh di Indonesia, yaitu sistem pendidikan di mana pengajar dan mahasiswa terpisah secara fisik atau geografis. UT berperan sebagai fasilitator dalam proses belajar mahasiswa yang bersifat akademik dan nonakademik seperti menyediakan beragam pilihan bahan ajar, media pembelajaran, layanan bantuan belajar, dan pilihan penilaian hasil belajar. Untuk menjalankan peran tersebut maka salah satu tugas yang dilakukan adalah memberikan informasi lebih awal, lengkap dan akurat kepada mahasiswa. Informasi diberikan langsung dari Kantor Pusat UT di Pondok Cabe, Tangerang, Banten dan unit program belajar jarak jauh (UPBJJ) UT yang tersebar di 37 kota di seluruh Indonesia. Contoh informasi yang diberikan adalah jadwal ujian akhir semester (UAS). Jadwal UAS dapat diketahui melalui katalog UT atau dapat diperoleh mahasiswa pada saat melakukan registrasi mata kuliah setiap semester di UPBJJ. UT menawarkan semua mata kuliah setiap semester dan masingmasing mata kuliah dilengkapi informasi jam ujian. Adapun tujuan diberikan jadwal ujian sejak awal adalah agar mahasiswa dapat memilih mata kuliah yang akan diregistrasi pada suatu semester. Mata kuliah yang dipilih adalah mata kuliah yang diujikan pada jam yang berbeda.

Judul: Evaluasi Efektivitas Sistem Distribusi Toko Buku Online Di Universitas Terbuka
Abstrak: One of the disadvantages faced by UT as an institution with distance learning system is the difficulty of distributing materials to students who are spread throughout the country, in this case UT has applied model of learning materials distribution through online, or better known as online book stores TBO-UT. This study aims to describe the distribution system of TBO-UT. The results shows that, (1) UT’s distribution system is able to increase the level of service in providing the learning materials for students, (2) the current distribution system capable of reducing the cost for students in obtaining the learning materials, (3) the current distribution system could increase the sales volume of learning materials as shown by the increase sales of UT’s modules from time to time. The results of this study also shows that students still face an obstacles in obtaining UT’s modules, this is due to several factors, (1) the delivery of learning materials is usually late from the schedule, (2) students have trouble paying the cost of learning materials since Bank Mandiri is rarely available at their residence, (3) access to UT’s website often does not run smoothly. However for students who work full-time, the service of UT TBO is really helpful. But for students who are unable to access the internet, this would be a barrier in obtaining learning materials.

Judul: Characterizations of low alloy steel sae 4422  plated with chromic acid (Cro3)
Abstrak: Characterizations of low alloy steel SAE 4422 plated with chromic acid (CrOrO3) was use Optical Microscopy (OM), Scanning Electron Microscopy (SEM), X-Ray Diffraction (XRD), RD),Energy Dispersive Analysis of X-Ray (EDAX), Hardness Test and Roughness Test. Microstructures analysis exhibits cracks and grain boundaries microcracks as a characteristics of chrome metal found at plating metal. Perlite and Ferrite as grains of steel found at base metal with grain boundaries around it. Phase analysis of plating metal appropriate to chrome metal with lattice constant (a) is 2.559 Å and phase analysis of base metal appropriate to iron ferrite with lattice constant (a) is 3.318 Å. Both plating and base metal have cubic system. Chemical analysis of plating metal at surface section exhibits that cracks area have highest value of carbon element compare with grains and grains boundaries area. While chemical analysis of base metal at cross section exhibits that perlite have highest value of carbon element compare with ferrite and grain boundaries. The hardness value of plating metal at surface section and cross section are 753 and 637 VHN. While, the hardness value of base metal and interface area at cross section are 205 and 373 VHN. The roughness value at measurement points of chrome surface for as received sample are 0.445 μm. Observation used Optical Microscopy and Scanning Electron Microscopy exhibits surface irregularities combine to form surface texture of plating metal at surface section.
