Based on data from the Ministry of Education and Culture Indonesian in April 2020, the Analysis of the Quick Survey of Learning From Home in Covid-19 Prevention Period, stated that the number of students who carried out interactive learning online with their teacher was less than 40% and the majority of students learned by doing questions from the teacher and learning independently from textbooks. The ideal teacher competence in online learning is a teacher who can implement video conferencing and can create online teaching materials. The pandemic came suddenly and the readiness of teachers and students in online learning is a factor in the effectiveness of teaching and learning activities in Indonesia. This educational social media design is purpose to facilitate teachers and students in collaborative learning that can be carried out by all teachers and students in Indonesia. This research produces output of educational social media design in the form of data flow diagram and interactive flow of application. The research method used is a combination of literature study and field study in order to obtain effective social media references for education category.</em></p> <p><em>The results of the research are in the form of data flow diagrams and interactive flow which can describe the concept of educational social media before being implemented into applications. Data flow diagrams are used for database design and database relationship on application data requirements, while interactive flow is the initial stage in making user interfaces application. So with the results of this research, a prototype of educational social media applications can be drawn as collaborative learning.</em></p> 2022-01-26T00:00:00+00:00 Copyright (c) 2022 Conference Series Prediction Of Graduation Time For Students Faculty Of Computer Science Amikom University Yogyakarta Using Naïve Bayes Method 2022-01-25T13:57:26+00:00 Adhy Syahputra Rum Mohamad Andri K. Rasyid Istiningsih Istiningsih Ardi Surwiyanta Haile Qudrat Djojodibroto Edy Anan <p><strong>The graduation rate on time in college cannot be taken lightly. In many cases, it is found that there is an imbalance in the number of students who enter and who have completed their studies so that there is a high accumulation of the number of students in each batch. It is necessary to know the factors that cause students not to graduate on time. Data classification techniques can be used to predict the timeliness of student graduation. The algorithm used is the Naïve Bayes algorithm with data from 122 students from the Informatics Engineering and Information Systems study program at the Faculty of Computer Science, AMIKOM University, Yogyakarta.

The success of teacher placement is determined by the minimum total distance between the teacher and the school, with the aim that teacher performance is maintained. In computer science this problem is an NP-hard problem that takes a very long time to achieve optimal results when done with conventional methods. Another approach to solve this problem is to use heuristic algorithms, one of which is by using genetic algorithms. To further improve the performance of genetic algorithms, one way is to narrow the search space. In this study, the problem will be broken down first through a clustering process so that the search space becomes narrower, before being subjected to genetic algorithm processes. This study will cluster the original data, before being subjected to a genetic algorithm to solve the problem of teacher placement. The clustering method used is the K-Means clustering method while the Genetic Algorithm uses the Ordered Crossover (OX) operator and the Partial Shuffle Mutation (PSM) mutation operator. From this study, it was found that by performing K-Means clustering before the optimization process using the Genetic Algorithm turned out to get better results than without using clustering. The total distance without clustering is 11751 km while with clustering it 9259 km. Also the total running time to execute this program turned out to be much shorter (from the order of hours to the order of minutes).</em></p> 2022-01-25T00:00:00+00:00 Copyright (c) 2022 Conference Series PCA Implementation In Identifying Risk And Return of LQ45 Stocks 2022-01-20T17:56:25+00:00 Irawan Wingdes Sahrul Nurfaizi Muhamad Rifki <p><em>Stock investing is a high-risk investment, so investors are constantly looking for ways to reduce risk while adapting returns. Lower risk stock groups are represented in Indonesia by the LQ45 index, which includes stocks with high liquidity, large capitalization, and good fundamentals. However, the index contains 45 members with varying risk and return. As a result, the price action analysis of the index's stock members is required to further reduce risk. This study employed principal component analysis to identify the index's various price action groups. PCA was used in Python 3 and produced two groups that explain 70.91% of the variance in the index's price movement. The stock groups derived from PCA were further analyzed, and ANOVA revealed that the groups differed significantly in return but not significantly in risk. The implemented PCA demonstrated potential return for a variety of investors interested in LQ45 stocks. </em></p> 2022-01-25T00:00:00+00:00 Copyright (c) 2022 Conference Series Feature Selection Technique for improving classification performance in the web-phishing detection process 2022-01-23T06:47:04+00:00 Anggit Ferdita Nugraha Dwiky Alfian Tama Dewi Anisa Istiqomah Surya Tri Atmaja Ramadhani Bayu Nadya Kusuma Vikky Aprelia Windarni <p><em>Web phishing is a type of cybercrime that occasionally threatens the online activities of website visitors. Web phishing uses a phoney website page that closely mimics the legitimate Website in order to fool its target into providing crucial information. Web phishing attacks also continue to grow in popularity year after year. As a result, it is vital to design a web phishing detection system in order to reduce the number of victims and financial losses caused by web phishing attacks. The development of a web phishing detection system continues to this day, with machine learning being the most often used model. Unfortunately, the construction of a machine learning-based web phishing detection system frequently employs only a single classification step; however, the feature selection process enables an increase in the performance of the resultant classification. Thus, an experiment was conducted in this paper by using a feature selection procedure based on the Pearson correlation algorithm prior to doing machine learning modelling utilizing popular algorithms such as Naive Bayes, Decision Tree, and Random Forest. As a result, using a web phishing dataset from the UCI Machine Learning Repository, it was determined that the addition of the feature selection process based on the use of decision tree and random forest algorithms resulted in an increase in accuracy of up to 94.60 percent and 95.50 percent, respectively, and a slight decrease in accuracy of 0.4 percent when implemented in the Naive Bayes algorithm.</em></p> 2022-01-25T00:00:00+00:00 Copyright (c) 2022 Conference Series Cheng's Fuzzy Time Series Method Implementation In Predicting The Number Of Covid-19 Positive Cases In Indonesia 2022-01-20T09:44:52+00:00 Andi Rafianto Rum Mohamad Andri Kristiyanto Rasyid Bernadhed Istiningsih <p><strong><em>At the beginning of 2020, citizens </em></strong><strong><em>all </em></strong><strong><em>around the world were </em></strong><strong><em>streaked</em></strong><strong><em> by the Corona Virus (Covid-19) pandemic which caused terror </em></strong><strong><em>far and near</em></strong><strong><em>.
