Muhammad Aji Darussalam, 2013. Development on Online Exam Application for University. Diploma III in Information Engineering, Faculty of Mathematics and Natural Sciences, Sebelas Maret University, Surakarta. Online examination system is part of the distance learning information system through the medium of internet technology. The concept of online exams \ud that are not limited by space and time, can be a solution to the problems that exist in the conventional test methods. This system aims to facilitate lecturers and students in examinations. Correction exam answer process that directly conducted by the system, makes the test more effective and efficient. Students can view the results at the end of test execution directly. The study was conducted by observing the system directly to obtain the results of the analysis of system requirements. As a basis and reference for making an online exam system, the literature study was conducted and then created a system and database design using DFD and ERD. The programming language was used PHP and MySQL as the database. In this system there are 3 levels of user : Administrator, Lecturers and Students. There are 4 types of questions options MCSA (Multiple Choice Single Answer), MCMA (Multiple Choice Multiple Answer), Essay and Ordering Answer. It can be concluded that the online exam application has been completed and has several main features, including the user data management, course management, news management, exam management, exam questions management and exam results management.

Analisis Rangkaian Pembagi Tegangan dan Perbandingan Hasil Simulasinya Menggunakan Simulator Offline

This paper reveals the voltage divider circuit to better understand the fundamental working principles in detail. The approach was simulated using popular offline simulators (i.e., Pr, CW circuit, and virtual mode, EWB, Mu, P, Ye, TS, QUCS, LTS, SI, and PhET). Two scenarios were carried out: measuring the output voltage (Vout) with known R1, R2, and DC source (Battery) as a voltage input (Vin), then looking for R1 and R2 using four different calculation methods to obtain Vout as expected. Afterward, the value of R1 and R2 were inserted into the simulation circuit to guarantee if the current Vout value matched the initial Vout. Finally, the simulation results were compared with the calculation results. All simulators provide an attractive GUI, capable of simulating voltage measurements with 100% accuracy in terms of DC analyses, which is DC voltage (except the CW software, which is only 98%), and can be entered in any resistor value (except Ye and PhET software). Surprisingly, the results of this study can provide insight for beginners to understand essential topics in electrical engineering studies, e.g., the circuit topology, fundamental theory, and working principle of a voltage divider circuit. Besides, the student will understand an offline electronic-based simulator suitable for measuring voltage parameters. Furthermore, they are expected to apply this circuit to various electronic circuit cases
