Abstract

The rapid development of digital technology has encouraged the creation of various intelligent systems that can support decision-making processes, one of which is an expert system. In the academic environment, students often encounter difficulties in determining appropriate thesis topics that align with their areas of interest. Therefore, this study aims to develop an expert system integrated with a WhatsApp chatbot to assist students in identifying suitable thesis themes based on their academic interests. The system employs the Depth-First Search (DFS) algorithm as a problem-solving approach due to its flexibility in exploring decision paths within the knowledge base. The expert system is implemented through a WhatsApp chatbot interface to ensure ease of use, as the messaging interface is already widely familiar among university students. This approach allows users to interact with the system naturally without the need to learn a new interface. The results of system testing indicate that the developed expert system effectively assists students in determining thesis topics. Evaluation results show an accuracy level of 95.4%, demonstrating that the proposed system provides reliable recommendations. Furthermore, the use of a chatbot-based interface enhances user accessibility and usability. In conclusion, the integration of an expert system with the DFS algorithm and a WhatsApp chatbot interface provides an effective and user-friendly solution for supporting students in selecting appropriate thesis topics based on their interests.

Abstract

Child literacy and financial literacy are important skills that need to be instilled from an early age to prepare children for future life challenges. This activity aims to improve children's literacy and introduce the basic concept of financial literacy through reading and coloring activities. The activity was carried out at the Kraton Village Library, Yosowilangun District, Lumajang Regency in August 2025, involving children from early childhood to elementary school. In this activity, children were given a storybook with the theme of financial literacy, followed by coloring activities with pictures related to the stories they read, such as pictures of piggy banks and money. The results of the activity showed that children not only improved their reading skills, but also gained a basic understanding of money management, such as saving and managing a simple budget. The involvement of parents in accompanying children also makes a positive contribution to strengthening the understanding of financial literacy at home. The success of this activity shows the importance of the role of village libraries as literacy centers that can integrate literacy and financial literacy. It is hoped that this activity can be used as a model to improve children's literacy and financial literacy in other regions in Indonesia.
