Abstract

Lingua Institute is a course institution that provides foreign language education and training. Student Management is the main service carried out by cross-functional divisions at Lingua Institute. This service focuses on student data as an object and includes matters relating to collecting, processing, storing, and distributing student data information. But Lingua Institute still has problems when running its business processes, such as the absence of rules and standard business process flow, therefore business processes run less effectively and efficiently; data recording and data storing are still manual so it is vulnerable to data loss; and delays in making learning modules. Therefore, analysis, evaluation and improvement of business processes are needed to solve these problems and to maximize the running of business processes. In this study, business processes are modeled using Business Process Modeling and Notation (BPMN), then analyzed and evaluated using the Failure Mode and Effect Analysis (FMEA) and Five Whys Analysis and finally improved by Business Process Improvement (BPI) method. Afterward, the current business process model and recommended business process model are simulated to validate and to indicate the time efficiency of the recommended business process. In a simulation of one business process, it is found that each activity is valid and there is a time reduction of 1 hour 2 minutes 16 seconds or an increase in time efficiency of 13.93%. This happens because of improvements such as changing some activities and utilizing Information System.

Abstract

Software cost estimation is an important aspect of an software project for budgeting. In the process of determining the price of a system in CV. The Profile Image Studio does not have specific estimation. because of that make often the company receive losses both financially and time. Based on this case, the cost estimation in this study will implement COCOMO II (Constructive Cost Mode IIl) method is implemented in calculating software costs suggestion for CV. Profile Image Studio. Cost estimates can be obtained after obtaining estimated effort, number of human resources and estimated system development time. COCOMO II (Constructive Cost Model) method is implemented in 2 systems that have been developed by CV. Studio Profile Image. At the end of this study, the cost comparison of system development was done by comparing estimated cost results obtained using the COCOMO II (Constructive Cost Model) with the allocation of costs by CV. Studio Profile Image. The results of applying the COCOMO II (Constructive Cost Model II) method in calculating software costs, it was found that the total estimated cost of the DBA ticket system was Rp.61.344.000 carried out by 3 people in 9 month while pintu air system was Rp.36.352.000 carried out by 2 people in 8 month. Difference in estimated cost for all software is 37,24% with time difference is 52,94 and people difference is 40%. So the COCOMO II method will be more precise in estimating cost of a project that can be minimize the losses received by the company.

Abstract

Higher education is the organizer of academic education for students where the quality of a college can be seen from the high level of success of students and the low failure rate of students. One indicator of student failure is a drop out case where it is also experienced by the study program Information System of the Faculty of Computer Science, University of Brawijaya. Based on the results of the interview obtained information that every year there are students of Information Systems who resign. The case certainly needs to be considered so as not to reduce the quality of education and university accreditation. So based on these problems a system is needed that is able to be a decision support to detect students who have the potential to drop out so that further action can be given. C4.5 algorithm is one of the algorithms in data mining that can be used to predict students who have the potential to drop out by generating rule in form of decision tree. The attributes used consist of academic data and student demographics of the study program Information Systems. The results from the calculation of confussion matrix are an accuracy rate of 98.85%. Meanwhile, based on the ROC curve, the AUC value is 0.8462. The output of this study is to make predictive applications for students who have the potential to drop out for the study program Information System by applying the C4.5 algorithm for the mining process on a system developed in the form of a website-based dashboard. Usability testing using the System Usability Scale (SUS) is 67.5 which is included in the adjective rating Good category and the acceptability level of users is included in the Marginal-High category.
