A reliable directory system was needed to guide people to the stores they wanted to visit. The developed mobile directory application was developed using a hybrid method that used the scrum method. A hybrid application is built using standard web technologies such as HTML, CSS, and JavaScript. To ensure the highest quality, a scrum development method is used so that the maximum value is produced. With the scrum method, a software product can be developed using stages that align with the requirements of its end users or clients. The stages taken in designing the system start from collecting data, identifying problems, analyzing user needs, designing applications, and implementing the system. As a result of the study, it was concluded that the scrum method facilitates the design and development of the application on time and precise, so that the intensive system development time efficiency will be achieved.

Abstract

Blood scarcity can be one of the main factors of life and death for patients who need blood. Therefore, organizations working in blood management Indonesian Red Cross try to spread information to invite people to donate blood. The spreading of information about blood donation is often done through social media. Twitter is one of the social media used in spreading this information. The method used to complete the system is waterfall by doing requirements analysis, design, development, testing and implementation. The information spreaded has very large amount. Each information can be classified into several data groups. There are many ways to classify information data, one type of classification used in making the system is unsupervised classification where the classification is carried out without supervision or often called clustering. The clustering method used is the k-means method. This technique can classify large amounts of data relatively quickly and efficiently. In clustering k-means method, the optimal number of clusters is needed so the results of clustering are better. To determine the optimal number of clusters, the Elbow method is used to obtain the best cluster value. The results of data grouping are presented in the form of visualizations, so that information becomes easier to understand quickly because it is supported by graphs and tables as well as responsive colors. The output of this research is a web-based analysis system that can classify the spreading of information obtained from the Indonesian Red Cross twitter account and visualize it in the form of diagrams.

Abstract

The Institute for Courses and Training is a non-formal education that provides various special training to educate students' skills. However, there are things that often become obstacles for prospective students, namely being confused about choosing courses according to their preferences. Therefore, the purpose of this research is to design an online course application with a recommendation system for the Content-based Filtering method. In addition, this research also applies the cosine similarity algorithm to determine courses that are similar to the course history that has been accessed by the user. The dataset used to run the recommendation system algorithm was taken from the Kaggle website entitled “Udemy Course” with a total of 3,682 records. The final result of this research is an online course application that can provide course recommendations based on the highest similarity value from the cosine similarity algorithm.
