This research discusses about online games which become ones of the most popular commodities, particularly among adolescents. It is suggested that they prefer spending time by playing online games to studying. Consequently, the phenomenon of online game addiction gets significant. The study aimed to explain and describe the use of Certainty Factor Method with expert system to diagnose online game addiction on adolescents. Its setting was Java island by involving some students as subject of the study. Survey method was employed to obtain the data while its instrument in terms of questionnaire was provided in Google forms and distributed to the students. An interactive qualitative approach was deployed to analyze the data combined with certainty factor method to show the level of game online addiction. The result shows from the sample of data which have analyzed addiction level toward online games is relatively moderate. Most of the users are adolescents between 12 and 15 years old and spend about 4 until 6 hours in a day. This condition becomes worse if there is no treatment for adolescents. Hence, there is a need of parents' control and awareness toward children's activity in playing online games since it renders negative impacts particularly on children's learning activity and motor development.

“…Certainty Factor has a function to provide accommodation to an expert from the uncertainty of thought. Certainty Factor provides a statement into an event either in the form of facts or hypotheses based on evidence or through expert judgment (Pakpahan et al, 2019). Certainty Factor is used as a measuring tool to determine the level of accuracy, honesty and trustworthiness when giving an assessment to a predicate.…”

Alignment of students with learning styles greatly affects the quality of learning of students in educational units. With good learning quality, the passing rate of students in an educational unit will also increase and can produce quality graduates. So far, the learning process implemented in this school has been going well when viewed based on the number of students graduating with the number of students present, but so far no further research has been conducted regarding this suitability so that the effectiveness of student learning is still not optimal. Based on this, the research objective is to build an Expert System with the Certainty Factor method to adjust the learning styles of students at SMK PGRI 5 Denpasar. Based on the results that will be obtained through the system designed and built in this research, it is hoped that it will make it easier for educators to prepare learning models and strategies that will be given to students from the results of determining student learning styles. The research results obtained from the test results show 100% suitability in giving dominant results to students' learning styles. In this study the students who were used as the test sample had different learning style percentage accuracy so that it could be used to determine the right learning style for each student.

“…The Certainty Factor method is claimed to be able to analyze conditions based on experience or experts and is able to provide solutions to problems that occur (Widians, Puspitasari, & Ameilia, 2018). The steps in using the Certainty Factor method to diagnose a disease or symptom are: make a list of each symptom (Safira, Irawan, & Setiningsih, 2019), create a disease and symptom code (Sembiring et al, 2019), build the weight of the CF rule of each symptom (Pakpahan et al, 2019), Building a table of interactions between diseases and symptoms (Pakpahan et al, 2019;Sembiring et al, 2019), build a CF user (Safira et al, 2019), dan calculating the CF value based on the Certainty Factor formula (Pakpahan et al, 2019;Safira et al, 2019;Sembiring et al, 2019). The results of the study will provide easy selfdiagnosis of Mathematics teaching efficacy beliefs of mathematics teachers.…”

Research on the design of an expert system to diagnose Mathematics Teaching Efficacy Beliefs (MTEB) using the Certainty Factor method was the first to be developed. The MTEB instrument was first initiated by Enoch and transformed into an expert system application using the paradigm of modified waterfall software development to sequential or sequential testing steps, ranging from analysis, design, coding, and testing. Data calculation and analysis using the certainty factor method assumes the user's choice is not exact and is at a certain interval. The weighting of expert values from MTEB items is carried out by two experts in the field of mathematics education. Meanwhile, the weight of user consultation uses five approval options, namely strongly agree, agree, simply agree, disagree, and disagree, successively represented by -0.2, -0.1, 0, 0.1, and 0.2. The results of the study gave success to each page of the diagnosis application, and the accuracy rate of the MTEB diagnosis was about 98%. The implication of this research is recommendations for related stakeholders to be followed up so that the MTEB of mathematics teachers becomes even better.
