Abstract

Information on the availability of parking spaces is needed for drivers. Drivers walking around looking for parking spaces have negative impacts, including traffic jams, waste of fuel, increasing pollution and even causing driver panic. Classification of parking spaces properly and quickly becomes a solution to present information on the availability of parking spaces. Based on the technology used, parking space classification usually uses sensors or computer vision. However, computer vision is lower in cost usage because a single camera can classify multiple parking spaces simultaneously. Convolutional Neural Network (CNN) is a popular method in dealing with vision problems. mAlexnet is one of the CNN architectures that has succeeded in classifying parking spaces well, but its accuracy still needs to be improved. A better architecture of mAlexnet needs to be made to improve classification accuracy and speed. In this study, we designed a CNN architecture named ParkingNet. Based on testing using sub-dataset camera B from the CNRPark dataset, ParkingNet is better than mAlexnet, both in terms of accuracy, the number of parameters, and FLOPs. ParkingNet managed to outperform mAlexnet's accuracy by 0.68%. Although not significant, ParkingNet is faster in classification due to the smaller number of parameters and FLOPs. The number of ParkingNet parameters is 4/5 mAlexnet parameters and the number of ParkingNet FLOPs is 2/5 mAlexnet. ParkingNet can be implemented in a smart parking system to classify parking spaces with lower computational costs.

Abstract

Augmented Reality is an activity that combines the appearance of virtual and real objects (objects) in real life and at that time will also display 3D objects that we want to see in real time. The process of combining virtual and real objects using technology that continues to develop rapidly in the world of design, interactivity is aimed at the input devices needed to support the goals to be achieved. Augmented reality technology at the Indonesian Army Attributes application is an application that uses the Markerless method with the Pattern Matching technique to display augmented reality 3D objects at the Indonesian Army Attributes. This application system can help users, especially prospective students (cassis) to make it easier for prospective students (casis) to achieve their goals of becoming an Indonesian Army Soldier, starting from the recruitment level and selection of units on duty. This technology can guide users to directly view 3D Indonesian Army Attributes objects without having to browse, not to mention network constraints when accessed, which takes longer. This application system is based on Android and can be accessed and used offline.

Abstract

Internet technology that is growing rapidly can be felt and is very much needed in arious fields of business in marketing their products online. such as building a marketplace application, Marketplace is an e-commerce service that becomes a meeting place between sellers and buyers online to process buying and selling transactions. With this marketplace, it can help companies offer their products and compete in a healthy manner, one of which is the Umrah and Hajj travel agency business, the Umrah and Hajj travel marketplace helps travel companies in marketing their products, healthy competition can occur, and prospective pilgrims have a lot of travel and activities. the desired departure package, in this application prospective pilgrims can order packages online and in real time, this application also has an attractive appearance and provides a menu so that it helps the congregation in carrying out their worship. This application is packaged in the form of an android-based application created using the dart programming language, flutter framework, and MySQL database
