Abstract

In this research, 64-bit Block Cipher Cryptography was designed based on the Social Media Logo Pattern, this design aims to produce a new cryptographic system, and aims to secure data or information in the form of text. In designing cryptography using Social Media Patterns, correlation tests have been carried out 24 times so as to produce the best pattern sequence with an average correlation value of 0.014425413 with a 1-2-4-3 sequence pattern. After finding the best pattern, 10 rounds are carried out where in each cycle there are 4 processes consisting of 4 patterns for the plaintext process and 4 patterns for the key process, and accompanied by S-Box substitution in each process so that the avalanche effect has a significant increase. In this research, the avalanche effect test was also carried out. In each avalanche effect test, it shows that the S-Box has an effect on the encryption process because in each cycle it has an avalanche effect that reaches 50%. So it can be said that the ciphertext generated by block cipher cryptography based on the social media logo pattern has random output results so that it can be used to secure data or information in the form of text

Abstract

This study uses a classification system in managing its data. In classification there are several methods provided, one of which is the decision tree method with the C4.5 algorithm this method means a decision tree where the structure is the same as a flowchart where each node signifies an attribute test, each branch presents the test results and the leaf node represents the class or class distribution. The data used is the data of Lake Poso Tourism visitors from 2009 to 2020, then the method used in this study is divided into several stages, namely the data being studied, analyzing the data, transforming data and designing a decision tree with the C4.5 algorithm. The results achieved from this study are that the number of visitors more than 28,984 has a description of "Much" which is dominated by local tourists, while the value with the name "Less" is in foreign tourists. This is one of the important points in determining the right strategy for developing tourism in Lake Poso.

Abstract

The development of e-learning system ini companies is very important in the learning process and training of employees or agents to achieve company goals. Like at PT. Global Infotech solution where the learning process still uses manuals so that it hinders learning because to hold training is quite large ini incurring costs for agents who are outside the region. Therefore companies need an e-learning system to help the employee agent learning process to be more affective. E-learning system have been developed and implemented using the moodle platform, which is one of the learning management system. The development method used is the ADDIE (Analysis, Design, Implementation, Evaluation) model so that it is faster ini developing an e-learning system platform according to user needs in the company. The results of the e-learning system research were assessed through employee agent responses from the learning aspect of 84.75% with a good category, seen from the display aspect of 86.05% with the very good category, seen from the aspect of the e-learning system using the Moodle platform of 80, 32% with a good category, and the last one seen from the material aspect in the e-learning system with an interesting concept of 89.82% with the very good category. So the overall assessment of the quality of the e-learning system as a whole is 85.25 with a good category. With this e-learning system, the learning process will be more efficient in displaying learning information needed by company agents in a web-based form and can be accessed by users online as long as they are connected to the internet.
