Abstract

In maintaining student satisfaction during online learning period, Petra Christian University conducted a survey to know student’s response. The result then processed manually and takes a long time to gather an information. Therefore, a sentiment analysis application is needed which will help to collect information from survey in a shorter time by classifying sentiments and topics related to online learning. The method used to classify topics and sentiments is the Naive Bayes Classifier. Data will be prepared through preprocessing, by eliminating the same sentence, changing abbreviated words, stemming, and stop word removal.The classification model produced and used in this application can classify student survey data related to the implementation of online learning based on positive and negative sentiments, also based on the topic, material, lecturers, learning media, and supporting facilities. The accuracy of the classification model is 89% for sentiment classification and 80% for topic classification.

Abstract

Currently, the process of working on a project or group assignment from the teacher will often experience a lack of control over the process.  The whole of a group work is only seen from the results and accuracy in the collection.  In fact, in addition to results and timeliness, teachers also need to know the process of each individual to understand their level of ability.Looking at the background of the problem, an application is designed that improves individual performance control in project work or group assignments.  This application will use a special framework to solve control problems, and can manage project work management to make it better.  Applications will be created using the PHP programming language and MySQL as a database. The results obtained from this application include the creation of a working website with a framework for project control to regulate existing work processes.

Abstract

Game-based Learning becomes one of the most developed learning methods in this 21st century. Game-based Learning is a good learning method because it can create a virtual world where players can simulate real world problem solving. Business process is a series of interrelated activities to achieve certain business goals which are executed sequentially or parallel, both inside and outside the company. The complexity of business processes causes the learning process to be less than optimal if only in the form of theoretical exposure. Practices are needed so that students can hone their business process management skills, but if they practice in the real world, of course it will be very high risk. Therefore, this research develops business process simulation game to facilitate students in practicing their business process management skill. The author analyzed the existing business process simulation games, determined the game system design, developed the game, tested the game, and distribute questionnaires to users. Based on the results of testing and implementing the system that has been done, the game developed in this research give a positive impact on users. The features in the game are running well and as expected. The game provides benefits to users, both teachers and students, so this game is suitable for being used as retail companies’ business process learning tool.
