Abstract

Infection symptoms are physical or mental characteristics that indicate a disease condition, especially those visible to the patient. The World Health Organization (WHO) issued a document containing symptoms of infection by the Covid-19 virus, including fever, dry cough, fatigue, and shortness of breath. These symptoms have similarities with illnesses caused by Influenza and Cold viruses, and it is difficult for most people to distinguish the differences between them. We proposed a Research and Development (RnD) study, developing an android app that embeds a Simple Additive Weighting (SAW) algorithm. However, this article will not cover the development process of the android app, but mostly how the algorithm works. This study aims to help people differentiate Influenza, Cold, and Covid-19 virus infections based on their symptoms through an Android-based application. We used weights provided by WHO and several related studies to be processed by the SAW decision-making algorithm, one of the Multi-Criteria Decision Making (MCDM) algorithms, a method that makes decisions based on multiple conflicting criteria. The user can get the most similar type of infection by entering the symptoms. The app showed its potential in achieving research objectives and the feasibility of being applied in the community.

Abstract

Computer network learning is learning that prioritizes practice compared to theory to be able to understand the material more clearly. Therefore, computer network learning requires real learning media to support learning effectiveness. However, because the cost of procuring computer network learning media is quite large, it is one of the main obstacles. By using a computer network simulator application is one way to overcome these obstacles. At this time there are several computer network simulator applications that can be used to support computer network learning activities to run efficiently. In this study, researchers evaluate and analyze several network simulation applications, to find out which applications are more efficient to use in learning computer networks, seen from the application capabilities in IP Address configuration, Subnetting, Routing. This study uses the observation method of computer network simulator applications that have been determined, namely the application of (1) Cisco Packet Tracer, (2) GNS3, (3) EVE-NG, (4) Boson Netsim, using the LORI research instrument version 1.5. This research has several stages, namely data collection, data reduction, scoring, data presentation, drawing conclusions and measured using a Likert scale. The results of this study indicate that the application (1) Cisco Packet Tracer ranks first with a value of 89.1%, (2) Boson Netsim is in second place with a score of 86.6%, (3) GNS3 ranks third with a value of 85.4%, (4) EVE-NG ranks fourth or lowest with a score of 83.3%.

Abstract

This study aims to group students into study groups (classes) based on learning styles utilising K-Means Clustering technique  and Sum of Squared Error for cluster assessment. This study used type of learning style developed by Felder and Silverman, which includes four dimensions: (1) the learning process; (2) perception of learning; (3) information input; and (4) understanding of information. This study subjects were Universitas Sebelas Maret's students majoring in informatics Education consisting of 58 respondents. The results showed that the K-Means clustering approach with cluster evaluation using Sum of Squared Error produced the best clustering when the number of clusters was k=2. The cluster analysis showed that each class has different learning styles and characteristics. The first cluster (group) consists of 26 respondents and has the features of an active learning style in the learning process dimension, sensing in the learning perception dimension, visual in the information input dimension, and a balance between global and sequential in the information understanding dimension. Meanwhile, the second cluster (group)  consists of 32 respondents and has a reflective tendency in the learning process dimension, sensing in the learning perception dimension, visual in the information input dimension, and global in the information understanding dimension.

Abstract

The problem of data security is essential because data must be maintained securely and in its integrity, starting with the sending procedure and ending with the intended recipient. One way to maintain data security is to use cryptographic techniques, which use data encryption characteristics to transmit messages in secret (information encoding). Information can be encrypted using the Caesar Cipher and One Time Pad, symmetric key cryptographic algorithms. The key must be changed as a critical component of the cryptographic procedure to enhance the data or text's security. This study aims to analyse text encryption on the Caesar Cipher and One Time Pad (OTP) algorithms using a modified symmetric key by implementing a Genetic Algorithm, an optimisation algorithm. The research phase begins by adjusting the key using two types of Genetic Algorithm crossover operators, one-point crossover and two-point crossover, applied to the Caesar Cipher and OTP algorithms. Then testing and analysis of the ciphertext strength are carried out by comparing the frequency of character repetition with the results of implementing the two modification keys to determine which encoding model provides a better data security strength.

Abstract

Teaching and learning can be effective and enjoyable if the course is well-packaged and presented. This was the experience of students and teachers participating in our hands-on Cyber Security course. Effective teaching of Cyber Security requires practical demonstration of attack patterns and their related countermeasures. This implies that outstanding and modern laboratories must be in place to teach and learn the necessary principles and practices effectively. Unfortunately, newly established universities in Sub-Saharan Africa need more funds for establishing and maintaining such laboratories. However, several researchers have shown that virtualization technology (VT) can enhance available but limited physical computing laboratories as an alternative to complex physical laboratories with huge procurement costs. This paper proposes an ad hoc and mobile laboratory for teaching practical principles in Cyber Security. The report aims to demonstrate the effectiveness of virtualization technology in teaching Cyber Security in newly established universities in Sub-Saharan Africa with zero to minimal computer laboratory infrastructure.

Abstract

The use of learning management systems (LMS) was observed to be weak among students in Nigeria. Therefore, digital literacy skills and system quality were used as predictors to predict LMS use among postgraduate students in universities in Ibadan, Nigeria.  A survey design of the correlational type was adopted. At the same time, the population of the study comprised all the 4,750 postgraduate students of two universities in Ibadan, Nigeria, and 328 postgraduate students were drawn using a multi-stage sampling technique. The instrument adopted for data collection was a questionnaire which had three sections. The questionnaire return rate was 316 copies, representing a 96.3% retrieval rate. Pearson’s Product Moment Correlation Coefficient and multiple regression analysis were conducted to test the null hypotheses at a 0.05 significance level. A significant relationship between digital literacy skills and the use of learning management (r =.319; p < 0.05) was found, while a significant relationship between system quality and the use of learning management systems (r =.501; p < 0.05) was equally established. There is a significant relationship between digital literacy skills and LMS system quality (r =.529; p < 0.05). Furthermore, a joint influence of digital literacy skills and system quality on the use of learning management systems of postgraduate students in universities in Ibadan, Nigeria (F =53.594; R=0.505; p < 0.05) was established. It was recommended that university management and lecturers should ensure the system quality of the LMS type to be adopted must support the convenience of use and have fewer technicalities in its use.
