Bagapit is a traditional game from Central Kalimantan. This game is usually done in free time or after doing daily tasks. This traditional game has begun to be forgotten, because of the rapid development of technology. In this day and age, people prefer to play games with gadgets. Therefore, to preserve and introduce this game to the wider community who are already familiar with technology, it is necessary to create a mobile-based bagapit game application. This game was made using the Multimedia Development Life Cycle (MDLC) method. This method consists of 6 stages, namely concept, design, collecting material, assembly, and testing. In this research, the system design is made by making use case diagrams, activity diagrams, storyboards, and User Interface designs. The material collected at the material collecting stage consists of background, object images, and audio. To determine the steps in the game, the Alpha Beta pruning algorithm and the MTD(f) algorithm are used. The making of this bagapit game uses the Godot Engine which uses the GDScript programming language. Testing is carried out using the black box testing method to ensure all functions in the game can function properly. This game consists of 3 levels that players can choose from. It is hoped that this game can introduce, provide insight, and preserve the bagapit game which is a traditional game typical of Central Kalimantan to the general public.

The enthusiasm of students to join online tuition centers is rising from time to time. It affects the number of tutors who have the important roles as the instructors. In the meantime, the students usually get information regarding the tuition centers from their colleagues or relatives. This affects the number of the students which is still minor. This indicates that the information about the existence of online tuition centers among societies has not been spread out widely. Mirroring on the lack, there is an idea appears. It is necessary to design a specific website for the online tuition centers. Besides its function as the promotion media, the website also provides access to learning materials. The learning materials which will be offered include theories, academic data manager and tabulation, and exercises with the tricks of how to finish them easily. This aims to help the students improve their achievements at school. The design of the application of these online tuition centers was constructed by the language program of PHP, MySQL basis data, and the methodology of waterfall. All stages of waterfall were started from analysis systems with business process, system design with DFD which includes diagram context, DFD Level 1, and DFD Level 2, ERD, and Data Dictionary. The process of managing and tabulating data which are in the system includes administrators, instructors, applicants and parents, where everyone has the access to the specific features.

Deep Belief Networks are deep learning models that utilize stacks of Restricted Boltzmann Machines (RBM) or sometimes Autoencoders. Autoencoder is a neural network model that has the same input and output. The autoencoder learns the input data and attempts to reconstruct the input data. The solution in this study can provide several tests on DBN such as detecting recall accuracy and better classification precision. By using this algorithm, it is hoped that we as users can overcome problems that occur quite often such as brute force attacks in our accounts and within the company. And the results obtained from this DBN experiment are with an accuracy value of 90.27%, recall 90.27%, precession 91.67%, F1-score 90.51%. The results of this study are the data values of accuracy, recall, precession, and f1-score data used to detect brute force attacks are quite efficient using the deep model of the deep belief network.
