Penggunaan Algoritma Naïve Bayes pada Klasifikasi Judul Proyek Akhir Berdasarkan Kelompok Bidang Kompetensi (KBK)

The Final Project is one of the graduation requirements that must be met by Caltex Riau Polytechnic students. The title of the final project is submitted by students through the SIAK system. Currently, students who submit titles will choose their own type of KBK from the inputted title. So that a problem arises where the title of the final project does not match the KBK it should or the KBK is wrong. This is due to the ignorance of students in analyzing the title data of the final project that will be submitted. For this reason, a system is needed to classify Final Project titles based on CBC automatically. The system created is a system that can classify KBK automatically based on the description of the title of the Final Project by using text mining methods and nave Bayes algorithms. The system can also detect the percentage of similarity of the entered title with the existing title in the system database. The algorithm used to generate the percentage of title similarity is cosine similarity with text mining method.

EVALUATING USER ENGAGEMENT AND READING BEHAVIOR ASPECTS OF WEB VISITORS BY ANALYZING INDICATORS ON GOOGLE ANALYTICS DATA

Nowadays, web-based technology is used as a source of information and marketing, one of which is educational institutions. This development unintentionally changes people's reading patterns, from paper to online media. However, user engagement and reading behavior on a web-based system is often overlooked while developing the plan. Understanding these two pillars can help the improvement process become more effective. Politeknik Caltex Riau has an official website that provides information about campus life and an introduction to study programs for prospective students. The information provided is quite complete and precise, yet there are many repeated questions. One example is the web visitors who are interested and asks about the registration steps, but the info is clearly on the website. Therefore, it is necessary to evaluate the understanding of the demographics, engagement, behavior, and events by implementing Google Analytics on the website. From the results, it is known that the visitors are on target. The majority of readers are high schoolers who are actively looking for university information. Many of them use smartphones to surf the website, though it is recognized that most readers do not read the content thoroughly. It can be seen from the total scroll event, which is only high at the beginning and keep decreasing while scrolling down the page. But the bounce and sessions number ​​keep rising. This phenomenon shows that the reader's engagement with the content is shallow, and reading comprehension is vague. In addition, there is also an indication of the effect of smaller screen size with the web design model as one of the reasons for the high jump rate. Thus, further studies can focus on deepening and evaluating web design and evaluating more indicators provided on Google Analytics.

An Exploratory Data Analysis for Synchronous Online Learning Based on AFEA Digital Images

The spread of COVID-19 throughout the world has affected the education sector. In some higher education institution, such as Polytechnic Caltex Riau (PCR), it is mandatory for students to participate in synchronous or asynchronous learning activities via virtual classroom. Synchronous online learning is usually supported by video conferencing media such as Google Meeting or Zoom Meeting. The communication between lecturers and students is captured as an image as evidence of students’ interaction and participation in certain learning subjects. These images can provide information for lecturers in determining students’ internal feelings and measuring students’ interest through facial emotions. Taking this reason into account, the current research aims to analyze the emotions detected in facial expression through images using automatic facial expression analysis (AFEA) and exploratory data analysis (EDA), then visualize the data to determine the possible solution to improve the educational process’ sustainability. The AFEA steps applied were face acquisition to detect facial parts in an image, facial data extraction and representation to process feature extraction on the face, and facial expression recognition to classify faces into emotional expressions. Thus, this paper presents the results obtained from applying machine learning algorithms to classify facial expressions into happy and unhappy emotions with mean values of 5.58 and 2.70, respectively. The data were taken from the second semester of 2020/2021 academic year with 1,206 images. The result highlighted the fact that students showed the facial emotion based on the lecture types, hours, departments, and classes. It indicates that there are, in fact, several factors contributing to the variances of students’ facial emotions classified in synchronous online learning.
