The problem addressed was the limited use of dropout prediction models, which had generally focused on algorithm performance and had not been integrated into an academic monitoring system design.This study aimed to develop a web-based prototype information system for predicting student dropout risk using the CatBoost algorithm to support academic monitoring. The development method used was Prototyping, while the prediction model was built from the Predict Students Dropout and Academic Success dataset, which was reduced to 3,399 records with two classes, namely dropout and graduate. The results showed that the developed prototype included manual prediction, CSV import, prediction monitoring, and role-based reporting features. The CatBoost model achieved 90.29% accuracy, 85.33% precision, 88.76% recall, and 87.01% F1-score. These findings indicated that the prototype had the potential to serve as a basis for developing an early detection system for students at risk of dropout.

Traffic violations are still common in the society. Traffic violation occurred due to lack of consciousness and obedience to the Society for orderly traffic so it is considered ordinary and habitual if allowed to continue. One of the traffic violation that often occurs in society is the vehicle driver breaking or crossing the traffic light when the red light is on. To overcome this problem, an application is built that can detect traffic light violation using OpenCV. In designing this traffic violation monitoring application, the author uses descriptive research design, While the data collection method used were literature study which includes scientific books, Scientific papers, scientific journals, thesis, and published sources in various media. The system analysis technique used is object oriented technique with modeling Unified Modeling Language (UML). Application design technique used Python programming language and OpenCV library, as well as database design used MySQL. This research resulted in an application of traffic violation monitoring by using OpenCV. With this application, it is expected to reduce the rate of traffic light violations. Based on research conducted, it is concluded that the built-in application can detect violations that occur at the traffic light using the OpenCV library. Keywords: Violation, Traffic Light, OpenCV

Tour guide is a profession in the field of tourism. Tour guides are responsible for accompanying tourists and providing directions and guidance to tourists. The tour guide must be able to explain the ins and outs of the places visited during the tour. Tour guides contain things that can guide visitors in exploring the entire area of tourist attractions and providing information about rides. Tourist guides are considered important because they are the reference for visitors in traveling at tourist sites. Tourism is everything related to tourism, including entrepreneurs of tourist objects and attractions and related businesses in that field. While traveling is a travel activity or part of these activities which is carried out voluntarily and temporarily to enjoy tourist objects and attractions. West Kalimantan is one of the tourist areas that has a variety of interesting tours. Most tourists visit West Kalimantan to see the natural and preserved culture and tourist attractions. Therefore, an Android-based application is designed to introduce these various tourist attractions to users, so new and appropriate innovations are needed to be better understood. So that users know some tourist attractions in West Kalimantan. This is the background for designing an application with the title "Designing an Android-Based Tourist Guide Application in West Kalimantan". The result of the research is to create an Android-based tourist guide application in West Kalimantan, which is expected to be able to provide convenience for users to find out tour guides and tourist information for West Kalimantan. The conclusion obtained by the author is that this application can display logins, registers, location of tourist attractions, show tour guides, verified status of tour guides and display detailed tour guide information.
