Abstract

The era of the industrial revolution, which was all technological, made all aspects continue to innovate so that they remained optimal, especially in the world of education. The current educational challenge is that there is still a lack of more interactive learning media using ICT, so that educators or teachers must be more extra in mastering technology in the manufacture and development of learning media. This study aims to develop learning media using classpoints that are easier on learning materials taught by each educator. With the same explanation as the previous ppt media with this feature there are many things to develop, especially in questions that the teacher can directly make on slides with various types of answers. The research model used applies ADDIE (Analysis, Design, Development, Implementation, and Evaluation) with a quantitative descriptive approach using interviews and questionnaires. A total of 36 students were the subjects in this study. With the results of the study showing that students answered above the range > 60% to 100%, it means that students agree to strongly agree that classpoint learning media is fun and interactive and easy to use.

Abstract

Generally, new prospective students often experience confusion in choosing a major in Computer Science, Informatics Engineering Program at Universitas Al Washliyah Labuhanbatu that truly matches their academic abilities and interests. Often, the decision to choose a major is influenced by the environment, such as following close friends or advice from parents, without considering the students' true potential and talents. However, choosing an inappropriate major can negatively impact their academic future and career. Therefore, it is crucial for prospective students to recognize and understand their academic abilities as well as their special interests and talents. The expert system for major determination developed using the Certainty Factor method is expected to provide an effective solution by combining various indicators of interests, talents, and academic abilities of prospective students. This method utilizes established rules to calculate the certainty level (CF value) for each possible major based on the data and characteristics possessed by the student. By combining CF values from various facts, the system can provide recommendations for the major that best fits the student's greatest potential. This model does not rely solely on academic scores but also considers special interests such as social, creative, and artistic talents possessed by students, making the major selection decision more precise and directed. Thus, this Decision Support System can assist the Faculty of Computer Science, Informatics Engineering Program at Universitas Al Washliyah Labuhanbatu in selecting truly potential new students and providing appropriate recommendations, thereby minimizing the risk of wrong major choices and increasing the likelihood of academic and career success for prospective students.

Abstract

Scientific article writing training is an essential skill for students and academics in conveying their research findings and scientific thinking. However, various challenges such as limited academic vocabulary, writing structure, and time often become obstacles. This study aims to develop effective writing strategies and evaluate Artificial Intelligence (AI)-based training as an innovative solution to improve the quality and productivity of scientific article writing skills and understand the ethics of using AI in academic writing. The method used was a quasi-experimental model with a structured training model, utilizing AI-based tools such as ChatGPT, Grammarly, and SciSpace. The results showed a significant increase in the quality and productivity of the training participants' writing. This training provides evidence that an AI approach can be an effective tool in academic literacy.
