Abstract

Social media is a means of online social interaction on the Internet, where users can freely share information. Because of the freedom, it cannot be denied that some people will misuse social responsible for misusing social media as a place to spread false news. Based on a survey of 2,032 respondents conducted by DailySocial.id in 2018, it was concluded that the majority of Indonesians do not have the ability to detect hoax news. Therefore, the research aims to design and build a hoax news detection application using the Android-based Multinomial Naive Bayes algorithm. At the design stage, the application is designed to receive input in the form of textual political news headlines. It then uses the Multinomial Naive Bayes algorithm to detect hoaxes by comparing the resulting text with data sets. In the testing phase, the algorithm is tested on a confusion matrix and shows the degree of hoax detection. The accuracy of the hoax detection is 88.9%, the precision is 93.33%, the recall is 84%, the recall is 84%, and the F1 score is 88.4%. With a detection application, it is hoped that this hoax news will be able to contribute to the online environment of the Indonesian people by verifying the information before sharing it on social media.

Abstract

Plagiarism can occur anywhere and can be committed by anyone. For example, plagiarism by students when creating college assignments, where they unintentionally use someone else’s writing or ideas and forget to cite the source. Based on the above explanation, it is necessary to develop an information system to assess the percentage of plagiarism for proposed titles. After conducting an implementation test to measure the similarity accuracy and processing speed, a comparison was made between the proposed titles and the existing data, totaling 940 titles. The results showed a similarity rate of 84.13% with the Rabin-Karp method, 61.24% with the Cosine method, and 42.86% with the Jaccard method. In terms of processing speed, the Rabin-Karp method ranked first with a time of 0.5023 seconds, followed by the Cosine method with 0.5095 seconds, and the Jaccard method with 0.5103 seconds. From the test results, Jaccard Similarity is more suitable for short texts with unique word sets, but it is less precise for longer texts with important word distributions. Meanwhile, the Rabin-Karp method is not designed to measure general text similarity; instead, it is intended for fast and precise substring searches in pattern matching contexts

Abstract

The integration of technology into qualitative research has revolutionised traditional methods, providing researchers with new opportunities and challenges. This paper compares the effectiveness, strengths, and limitations of traditional versus technology-based methods for recruiting participants, conducting interviews, and transcribing data, based on the personal experiences of the researchers. The findings reveal that while traditional face-to-face interviews enable deeper personal interaction and richer data collection, they are often time-consuming and logistically challenging. In contrast, technology-based methods offer increased accessibility, efficiency, and flexibility, particularly when recruiting participants and conducting interviews among geographically dispersed populations. However, these methods may compromise the depth of data due to the challenges of maintaining non-verbal cues and transcription accuracy, particularly when using automated transcription tools. This paper recommends a hybrid approach that combines the strengths of both methods. Best practices for using technology in qualitative research are proposed to ensure the richness and contextual depth of the data while leveraging the benefits of modern tools.

Abstract

The Profile Matching method is a technique in decision support systems that is used to analyze the conformity of criteria with predetermined standards. In the context of determining mental disorder status, this method plays a role in identifying individuals based on certain mental health criteria. The process involves comparing an individual's profile with a standard profile that describes the characteristics of mental disorders. The criteria analyzed include aspects of the indicators, namely; Emotional, Physical, Behavioral and Psychological relevant to mental health. This method is able to provide objective recommendations because it uses weight-based calculations for each criterion. This Profile Matching-based decision support system can help health workers and decision makers at the village level to identify and group individuals with mental disorders, so that appropriate interventions can be determined. With this system, the process of evaluating people's mental health conditions can be carried out more accurately and efficiently. This method is one method of determining the indication that a person is classified as an ODGJ with the indicators, namely; Emotional, Physical, Behavioral and Psychological. Based on research results from 5 patients who were tested using the Profile Matching method, the following results are in the highest order; Patient F had the highest score, namely 3.7, patient R, namely 3.4, patient C, namely 3.3, patient S, namely 3.2 and the smallest was patient A, namely 3.0. It is hoped that it can increase early detection of mental disorders, as well as speed up follow-up treatment or referral to further mental health services.

Abstract

Artificial intelligence based programs are used in various fields of daily life, often without our awareness. With the increasing integration of artificial intelligence applications into the educational system, accessing information has become faster. As a result, chat programs that produce text-based answers similar to those of humans are being used as educational tools. The accuracy of the content generated by these programs has always been a topic of interest. In our study, we evaluated the success of ChatGPT, Gemini, and Copilot applications in answering dental specialty exam anatomy questions from 2012-2021. In the computer environment, free versions of ChatGpt-4, Google Gemini and Microsoft Copilot were accessed. The responses were recorded as either correct or incorrect. Out of 74 anatomy questions ChatGPT, Gemini and Copilot gave 2, 10, and 1 incorrect answers, respectively. Although the evaluated programs showed sufficient success in answering anatomy questions, their use was deemed limited due to errors in the supplementary information they provided.
