Abstract

Since the pandemic of Covid-19 was happened in Indonesia, the government shared the letter of The Ministry of Education and Higher Culture Education Directorate No.1, year 2020 about prevention of the spread of Corona Virus Disease (Covid-19) in higher education. Through the letter, The Ministry of Education and Culture gave an instruction for college to organize online learning and suggested students to study at their home. Online learning which was considered as a strategy then became a controversy because it needed adaption. This sudden change from normal learning to online learning caused many responses from students. The aim of this research was to analyze student sentiment or responses on online learning in this pandemic era of Covid-19 in Indonesia by using data which had been collected using questionnaire and processed using naïve bayes classifier method. This research was case study descriptive quantitative research. The research was done by collecting the data first. The data was collected through questionnaire with the question about their opinion on online learning in this pandemic Covid-19 era. The data was 157 student’s data opinion on online learning. After the data was collected, the data was cleaned first from question mark and the words which didn’t give an effect in sentiment analysis. After the data was cleaned, then the result of the classification will be showed as well as the accuracy which the model earned. The result showed that online learning had negative sentiment more than positive sentiment. The height of negative sentiment was caused by discomfort of student in online learning. The word which frequently showed was ‘tidak efektif’, ‘susah’, and ‘tugas’. The accuracy of this model was 75% when the result of this accuracy was good result in classification.

Abstract

The issue of security and confidentiality of data or messages is very important so efforts are needed to maintain the security and confidentiality of messages, one of which is with cryptography. This study aims to determine the implementation of the RSA algorithm over the Dedekind ring to secure text messages. This implementation is done by modifying the key formation, encryption, and decryption processes of the RSA cryptographic algorithm to match the Dedekind ring used. The research stage carried out is to form a key on the RSA algorithm over the Dedekind ring, then construct an encryption and decryption algorithm to secure messages with RSA over the Dedekind ring. From this research, results were obtained in the form of an RSA message encoding algorithm in accordance with the Dedekind ring where the Dedekind ring was used in the key formation process. Furthermore, the encryption and decryption process is carried out with the RSA algorithm. The conclusion of this study is that the implementation of the RSA algorithm over the Dedekind ring can produce a wider public key where the public key used is any member number of the set of maximal ideal products on the Dedekind ring.

Abstract

The generalized Euler-Mascheroni constant analyzes functions or sequences with specific parameters in various scientific fields. As scientific knowledge advances, the generalized Euler-Mascheroni constant continues to undergo renewal. One example is found in "On Generalized Euler-Mascheroni Constants" by G. Abe-I-Kpeng, M.M. Iddirisu, and K. Nantomah in 2022. The purpose of this study is to analyze the relationship between the generalized Euler-Mascheroni constant and harmonic series, as well as to examine its connection with signed count permutations. The analysis involves decomposing the Riemann Zeta function and using Stirling numbers of the first kind. The methodology employed in this study was literature research. This study yields new theorems concerning the generalized Euler-Mascheroni constant.

Abstract

The Ebola virus is a deadly disease that causes blood clots in the body's organs and is spread through direct contact with the blood or body fluids of sufferers. Based on this, the immune system in the body will continue to decrease and cause Ebola Hemorrhagic Fever. The 2014-2016 Ebola outbreak in West Africa has accelerated the development of several preventive vaccines against the Ebola virus. The goal of the vaccination is to induce immunity against infectious diseases. And also to stimulate the immune system and its ability to store and remember information about specific pathogens, leading to long-term protective immunity. The model equation for the Ebola virus vaccine in this study involves the concentration of the antigen which is a variable , by means of which the vaccine is inserted into the patient's body where it will attach to B memory cells which are variable , which will then be stimulated by the cells short-lived antibodies are denoted by variables  or long-lived cells are denoted by variables , while antibodies will prove efficacy denoted by variables  on the patient's immune response. The simulation of the exact solution for the Ebola vaccine uses the integration factor method which will later be compared with numerical simulations according to the parameter values from the research of Irene Balelli et al (2020). The simulation obtained has a very small calculation error value for each variable, which means that the exact value of the Ebola virus vaccination model shows that there is no significant difference to the numerical solution using the order 45 Rungge Kutta method, the largest resulting numerical error is 2.29640283510782×〖10〗^9.

Abstract

Vigènere Cipher is a symmetric cryptographic algorithm that uses the same type of key in the encryption and decryption process. The security of the Vigènere Cipher method lies in the modulo calculation used. ElGamal is an asymmetric cryptographic algorithm that uses two different types of keys in the encryption and decryption process. The security of the ElGamal algorithm lies in the complexity of calculating large prime numbers. The Vigènere Cipher and ElGamal have their advantages and disadvantages. The researchers are interested in combining the advantages of the two methods. In this study, two locks were carried out in the encryption and decryption process. The encryption process uses a public key and the decryption process uses a public key  and a secret key . The key used comes from key formation using the ElGamal algorithm. The key security formed from the ElGamal algorithm lies in the large prime , the primitive root  of the prime number , and the random integer  which comes from the last three digits of Student Number. The conclusion of this study is that the combination of the Vigènere Cipher and ElGamal methods can increase the security of  secret messages because it produces a ciphertext with twice the size ) of  the original message.
