Abstract

Queues can be found in all aspects of life, especially in the service industry, including at Binus University in the Student Service Center. Sizeable number of students at certain arrival time, has led to a long queue and this affects student discomfort in waiting. Queue information systems that exist today should bedeveloped further in order to improve the comfort of the user, such as information that is integrated with a student desk, both in seeing a queue number, and knowing the history queue. The research method used is thethree phases of the Software Development Life Cycle methods Problems and Opportunities, System Requirements and System Design. The result of this research is a framework that can be used for queuing system so as to provide the freedom of time and space for the user waiting queue.

Abstract

If there is a stack in a service center, then the customers need to form a queue. There are increasing number of consultations in a specific time at Student Advisory Center (SAC) Bina Nusantara University. The increased needs for consultation lead to high waiting time that must be passed by the students who need the service. Therefore an information system queue is required to replace the current manual queue process. This study aims to create an automation using six stages FAST Methodology which includes Scope Definition, Problem Analysis, Requirement Analysis, Logical Design, Decision Analysis, Physical Design and Integration. The results of this research is the design of the application queue screen can be applied to SAC Bina Nusantara University.

Abstract

Sorting is a basic algorithm studied by students of computer science major. Sorting algorithm is the basis of other algorithms such as searching algorithm, pattern matching algorithm. Bubble sort is a popular basic sorting algorithm due to its easiness to be implemented. Besides bubble sort, there is insertion sort. It is lesspopular than bubble sort because it has more difficult algorithm. This paper discusses about process time between insertion sort and bubble sort with two kinds of data. First is randomized data, and the second is data of descending list. Comparison of process time has been done in two kinds of programming language that is C programming language and FORTRAN programming language. The result shows that bubble sort needs more time than insertion sort does.

Abstract

The purpose of this study was to determine the extent to which the use of a web application to improve efficiency and effectiveness of administrative work. The research method used consisted of the analysis phase, study libraries to support application design and data collection based on observations. Results of evaluation and observation data before and after implementation of the system showed that the use of a web application to improve efficiency and effectiveness of administrative work, e.g. by decreasing the length of time the making of letter, an increase in the percentage of the making of timeliness, accuracy of data validation and provide facilities for students in order letter as well as convenience for staff in the making of letter. Another thing is the ease in monitoring the accuracy of the making of letter.

Abstract

Mentoring supports the success of student’s study in almost all colleges. Mentoring activities include consulting, mentoring and enrichment materials, and monitoring the achievement of study for all students. Along with the growing number of students, encountered several obstacles in the process of mentoring such as the limitations of time and place to hold mentoring, the availability schedule given by the mentor, and the inadequate number of mentors. Research methods used include field studies, literary studies, problem identification, and problem analysis. To provide appropriate solutions in response to the existing problems, an information system of mentoring is designed.

Abstract

This study aims to determine the benefits of a web application in improving the efficiency and effectiveness of services to lecturers. The research method consists of literature study and data collection analysis based on observations. Implementing a web application, an observation is conducted followed by a comparison on data prior to the implementation. The evaluation results show that the implementation of a web application improves efficiency and effectiveness in the use of time and resources in providing services to lecturers in information access.

Abstract

This research aims to help universities that do not have an academic information system and facilitate EPSBED data report to Directorate of Higher Education (DHE). The method used is the three first stages in the System Development Life Cycle (SDLC), which are systems engineering, requirements analysis, and design system. The result is a design of university business process, design of database, and design of user interface. This research finds that DHE has a specific data structure that can represent the basic activities of a study program. Therefore, this system design can be used for reporting of EPSBED data as well as for data collection of study program activities.
