Most solutions to the problem of delivering course content supporting both student learning and assessment nowadays imply the use of computers, thanks to the continuous advances of information technology. According to Bull (1999), using computers to perform assessment is more contentious than using them to deliver content and to support student learning. In many papers, the terms computer-assisted assessment (CAA) and computer-based assessment (CBA) are often used interchangeably and somewhat inconsistently. The former refers to the use of computers in assessment. The term encompasses the uses of computers to deliver, mark, and analyze assignments or examinations. It also includes the collation and analysis of data gathered from optical mark readers. The latter (that will be used in this paper) addresses the use of computers for the entire process, including assessment delivery and feedback provision (Charman & Elmes, 1998). A typical CBA system is composed of the following. • Test-Management System (TMS) - that is, a tool providing the instructor with an easy-to-use interface, the ability to create questions and to assemble them into tests, and the possibility of grading the tests and making some statistical evaluations of the results • Test-Delivery System (TDS) - that is, a tool for the delivery of tests to the students. The tool may be used to deliver tests using paper and pencil, or a stand-alone computer on a LAN (local area network) or over the Web. The TDS may be augmented with a Web enabler used to deliver the tests over the Internet. In many cases, producers distribute two different versions of the same TDS: one to deliver tests either on single computers or on a LAN and the other to deliver tests over the WWW (World Wide Web). This is the policy adopted, for instance, by Cogent Computing Co. (2004) with CQuest LAN and CQuest Net. The TMS and TDS modules may be integrated in a single application as, for instance, Perception developed by Question Mark Computing (2004), or may be delivered as separate applications as it occurs for MicroTest and MicroGrade developed by Chariot Software Group (2004).

Modernization causes the examination process in some educational institutions that are usually done conventionally now start to change to CBT (Computer Based Test). At STMIK Atma Luhur, CBT in the form of a coding test carried out on a computer laboratory was felt to be not effective enough due to a short correction time, as well as the possibility of lossing the students work due to sudden power failure. Collection of jobs using an LAN (Local Area Network) intranet network can not be realized due to the difficult network configuration and requires not a small cost. One solution that can be offered in overcoming the above problem is to create a web-based exam application that is connected to a Wireless Local Area Network (WLAN) intranet network. The system development model and tools used in this study are prototype models and UML (Unified Modeling Language). The proposed application is effective in facilitating and accelerating the process of collecting student answer files from several client computers to a server computer. In addition, the usage of the proposed application allows the lecturer not to correct students' answers in a hurry, so that the scores that are truly objective and can be accounted for are obtained.

The number of educational institutions seeking solutions to the problems associated with the burden of expanded student numbers is increasing every day. Most solutions to the problems of delivering course content, supporting student learning, and assessment may be found through the use of computers, thanks to the continuous advances of information technology. According to Bull (1999), using computers to perform assessment is more contentious than using them both to deliver content and to support student learning. In many papers, the terms Computer Assisted Assessment (CAA) and Computer Based Assessment (CBA) are often used interchangeably and somewhat inconsistently. The former usually covers all use of computers in assessment, including reporting and marking, such as in optical mark reading. The latter is often restricted to the use of computers for the entire process, including delivery of the assessment and provision of feedback (Charman and Elmes, 1998). In this paper we will adopt the term Computer Based Assessment and we will discuss some issues related to the online assessment of students.

Performa sebuah server saat ini menjadi salah satu kunci untuk menilai apakah sebuah servis yang bergerak dibidang aplikasi digital termasuk baik atau tidak. Salah satu servis yang sering digunakan pada saat ini adalah sistem ujian online atau yang lebih dikenal dengan istilah CBT (Computer Based Test). Dimana pada servis ini membutuhkan performa server yang mumpuni untuk melayani siswa dalam mellihat soal dan juga mengoreksi jawaban siswa secara realtime. Permasalahan yang ada saat ini adalah para penyelenggara CBT seperti sekolah, institusi pendidikan dan lain sebgainya belum memiliki patokan server yang efisien dalam menentukan spesifikasi server yang sesuai dengan kebutuhan. Terlebih lagi teknologi mikro server saat ini yang banyak dikembangkan di luar negeri memberikan sebuah kesempatan untuk menerapkan servis ujian online ini lebih marak dan dapat digunakan untuk masyarakat Indonesia secara luas. Pada penelitian kali ini server akan diuji menggunakan metode pengujian yang bertumpu pada 2 bidang besar yakni sumber daya server dan juga jaringan komputer. Dimana untuk sumber daya server kali ini kita akan melihat bagaimana penggunaan sumber daya mikro server saat menjalankan servis ujian online/ CBT. Berikutnya adalah pengujian dari sisi jaringan komputer dimana pada sisi jaringan komputer disini kita menggunakan metode simple network testing tools dan melihat bagaimana aktifitas jaringan komputer yang berjalan pada mikro server saat menjalankan servis ujian online/ CBT. Hasil yang dapat ditarik dari metode pengujian yang telah dilakukan adalah dari sisi sumber daya server adalah penggunaan prosesor lebih dominan digunakan daripada penggunaan RAM pada mikros server hal ini dibuktikan dengan rata-rata pengujian didapatkan hasil penggunaan prosesor adalah 55,5% dari 100% sedangkan penggunaan RAM adalah 35,7% dari 100% hal ini dikarenakan prosesor memproses jawaban yang telah dikirim oleh siswa dan dilanjutkan pada proses input pada database yang ada pada server, sedangkan RAM berfungsi sebagai menyimpan beberapa komponen web yang akan ditampilkan pada client dimana semakin besar file yang digunakan pada sistem CBT juga akan mempengaruhi berapa besar RAM yang akan digunakan. Dari sisi jaringan komputer didapatkan hasil pengujian ping menuju server memiliki rata-rata keberhasilan mengantarkan paket 95% dan memiliki rata-rata kegagalan mengantarkan paket 5% hal ini diakibatkan oleh keterbatasan perangkat jaringan komputer khususnya perangkat jaringan wifi yang memiliki keterbatasan dalam memproses paket yang keluar dan masuk. Berdasarkan penelitian diatas dapat disimpulkan bahwa penggunaan mikro server pada sistem ujian online/CBT dengan jumlah 35-40 siswa dapat digunakan secara lancar. Sehingga dengan hasil ini maka sekolah yang ingin menerapkan sistem ujian online dapat memanfaatkan mikro server sebagai alternatif pengganti server yang mahal. Terlebih lagi penggunaan mikro server dapat menghemat dari sisi biaya pembelian dan juga biaya listrik dikarenakan mikro server memiliki spesifikasi yang rendah dan juga penggunaan listrik yang sangat kecil dan memungkinkan dapat menggunakan baterai.

System Use

A local area network of six microcomputers provided 32 seventh-grade, LD and Chapter One students and their teachers with increased capabilities to access information associated with academic performance. Specific information in the system included descriptions of all academic tasks assigned to students, as well as such basic specifications as date due and point value. As each quarterly period of instruction within the school year progressed, the system accumulated a complete performance record for each student. Students, resource teachers, and mainstream teachers were able to request up-to-the-moment reports of pending assignments, missing work, grades on particular tasks, and estimated overall course grade. Findings obtained during a 27 week field test underscored the feasibility and potential significance of such a system. System use by students and teachers occurred at high levels. All participants indicated that system use was a positive experience and that system operation was important. A significant, positive correlation was obtained for student use and completion of academic tasks. Further potentials for such a computer-assisted information system are evident, including significant forms of home-school linkage and automatic recognition of student performance.

This report focusses on the planning and realization of an interdisciplinary local area network (LAN) for medical research at the University of Heidelberg. After a detailed requirements analysis, several networks were evaluated by means of a test installation, and a cost-performance analysis was carried out. At present, the LAN connects 45 (IBM-compatible) PCs, several heterogeneous mainframes (IBM, DEC and Siemens) and provides access to the public X.25 network and to wide-area networks for research (EARN, BITNET). The network supports application software that is frequently needed in medical research (word processing, statistics, graphics, literature databases and services, etc.). Compliance with existing “official” (e.g., IEEE 802.3) and “de facto” standards (e.g., PostScript) was considered to be extremely important for the selection of both hardware and software. Customized programs were developed to improve access control, user interface and on-line help. Wide acceptance of the LAN was achieved through extensive education and maintenance facilities, e.g., teaching courses, customized manuals and a hotline service. Since requirements of clinical routine differ substantially from medical research needs, two separate networks (with a gateway in between) are proposed as a solution to optimally satisfy the users’ demands.
