Abstract

The rapid development of artificial intelligence (AI) has opened new possibilities for enhancing user interaction within video games. This study presents the design and implementation of a button-based assistant system for the simulation game Story of Seasons: Friends of Mineral Town, aimed at simplifying repetitive player tasks and improving the overall gameplay experience. The proposed system leverages a hybrid approach that combines Machine Learning and Deep Learning techniques, specifically Optical Character Recognition (OCR) with Tesseract, object detection using a custom-trained YOLOv7 model, the A* pathfinding algorithm for navigation, and automated input control through scripting. The assistant is capable of reading in-game time, weather, and events directly from screen captures, recognizing non-player characters (NPCs), and automatically directing the player’s character to desired locations or NPCs based on contextual data such as day, time, and weather conditions. A database-driven module stores key information such as NPC schedules, favorite gifts, and daily events to enable informed decision-making and interaction automation. Comprehensive testing was conducted, including comparisons of pathfinding algorithms, model accuracy assessments, and user experience evaluations involving volunteers. Results showed high detection accuracy with YOLOv7 and positive user feedback on the assistant's interface and usability. Users reported a more streamlined and enjoyable gaming experience, especially in managing daily tasks and character interactions. This research demonstrates how a hybrid AI-based approach can be effectively applied to traditional video games, offering a foundation for future development in intelligent game assistance systems. The proposed methodology not only improves convenience but also provides insights into the practical integration of AI in user-centric game design.

Abstract

Internet merupakan salah satu sumber informasi yang sangat mudah diakses dan sangat lengkap pada zaman sekarang ini. Dari banyaknya konten tersebut terdapat konten pornografi yang meresahkan dan memberikan dampak buruk pada perkembangan anak-anak. Hingga tahun 2020 pemblokiran konten pornografi menyumbang 70 persen dibandingkan konten negative lainnya. Metode untuk mencegah/memblokir konten pornografi ada berbagai macam mulai dari memblokir websitenya hingga mendeteksi berdasarkan citra yang ada. Penelitian ini akan mencoba mendeteksi citra pornografi dengan bantuan Deep Convolutional Neural Network. Pembuatan model menggunakan transfer learning hingga fine tuned fine transfer learning dan mencoba model-model state of the art. Penelitian ini menghasilkan model yang mampu mendeteksi citra pornografi dengan akurasi 78%. Selain memiliki akurasi yang cukup tinggi model ini juga mampu mendeteksi bagian-bagian intim dari wanita yang menjadi fitur dari citra pornografi. Kemampuan mendeteksi fitur tersebut telah diujicoba dengan mengubah model yang digunakan penelitian ini sebagai detektor objek pada citra pornografi.

Abstract

This research discusses how the Harris Hawk Optimization (HHO) algorithm handles scheduling problems. The scheduling of thesis defenses at the Institut Sains dan Teknologi Terpadu Surabaya (ISTTS) is a complex issue because it involves the availability of lecturers, teaching/exam schedules, lecturer preferences, and limited room and time availability. The scheduling constraints in this research are divided into two categories: Hard Constraints and Soft Constraints. Hard constraints must not be violated, including each lecturer's unique availability, conflicts, and existing exam or teaching schedules. Soft constraints, on the other hand, include preferences for specific days or rooms for the defense. The complexity of scheduling due to these two types of constraints leads to longer scheduling times and an increased likelihood of human error. To automate and optimize this process, the author employs the HHO algorithm. HHO is inspired by the behavior of the Harris Hawk, known for its intelligence and ability to coordinate while hunting. The results of the HHO algorithm are translated into a slot meter, which helps to map the solution to available time slots. The HHO algorithm can generate schedules that comply with 90% of the hard constraints at ISTTS. Evolutionary algorithms typically have high complexity and computational time; in this case, the researcher experimented with multiprocessing. Multiprocessing improved the computational time by up to 39%.
