Abstract

Security and confidentiality issues are one of the important aspects of data, messages and information. One technique that can maintain data confidentiality is cryptography. Vigenere Cipher is one of the classic cryptographic algorithms that works by reading words per character, where if the message sent exceeds the length of the key used, the key will be repeated until the message sent gets each key. The system implementation uses Visual Basic 2010 programming language and the method used in this research is waterfall, this application is designed using UML (Unified Modeling Language). The result of this research is a software application that is useful for maintaining the confidentiality of messages with the Vigenere Cipher algorithm method. With this application can be one solution in securing data in the chat process.

Abstract

A reseller is someone who resells products from a supplier to consumers using the reseller's price. The role of resellers cannot be separated from business competition. Resellers are one of the sales methods used by sellers to sell products to customers. For CV. HKM Bengkulu, it is certainly not an easy task to evaluate the performance of resellers achieved by each reseller for the company. Therefore, a computerized decision-making system is needed to assist and simplify the selection of the best reseller. Decision Support System (DSS) research method used in this study is the waterfall method. COPRAS method analysis that will be carried out in this research will describe the stages needed to implement COPRAS in selecting the best reseller at CV. Harapan Karya Mandiri Bengkulu. To perform the calculation process using COPRAS method, the determination of alternatives (An) and criteria, as well as the weights of each criterion, will be conducted. The criteria used are payment type, transaction volume, total spending, quantity of purchases, and subscription duration. The conclusion of this research explains the results of the calculation using COPRAS method, where the reseller with the highest value will occupy the highest ranking followed by the reseller with the lowest value.

Abstract

The selection process for scholarship recipients in higher education requires a measurable system. The problem that has been happening is that the procedures carried out by the scholarship provider still use a manual file examination system. Composite performance index is the method used in this study. The purpose of this study is to create a decision support system for the selection of scholarship recipients to be more systematic and time efficient in the process. There are 10 alternatives and 4 criteria, namely parental income, GPA, electricity usage ,and semesters. The results of this study were obtained 5 highest values are A7 t with a value of 235.00 rank 1, A4 with a value of 200.00 rank 2, A1 with a value of 134.14 rank 3 sequences, A5 with a value of 120.00 ranks 4, and A8 with a value of 91.67 sequences 5.

Abstract

The use of computer networks at SMK Negeri 3 Kota Bengkulu increases the need for security against threats such as illegal access and DoS/DDoS attacks. This study implements a Mikrotik firewall using Filter Rules, Raw Rules, Mangle Rules, and DDoS limits using the Security Life Cycle (SLC) method.Test results show that Filter Rules are effective in blocking illegal access, Raw Rules are efficient in handling volumetric attacks because they work before connection tracking, and Mangle Rules are useful for traffic management. The application of DDoS limits has been proven to reduce the number of excessive connections so that the network remains stable.This study proves that the Mikrotik firewall can enhance school network security and can serve as a reference for implementing more comprehensive security policies

Abstract

In a school, the ranking of outstanding students is usually only selected based on their final grades, as is the case at SMK 02 Bengkulu City. The selection of outstanding students at SMK 02 Bengkulu City is only based on report card grades ranked 1 to 5. This selection process has many opportunities to make wrong decisions because the student selection process is only based on one aspect, namely the student's final grades, while the attitude and achievement scores obtained outside of school are not taken into consideration as additional criteria for determining students who are considered outstanding and receive scholarships. This means that there is a high probability that the selected outstanding students do not meet the desired standards and do not get the best candidates. The purpose of this study is to provide an alternative way for schools to determine outstanding students so that it is not only based on academic grades, and there is no cheating in the selection of outstanding students. The method used in this study is the Preference Selection Index (PSI) method. The results of this study show that the PSI method can provide the best results from the predetermined criteria and weights.

Abstract

Cultivating chili plants is a business opportunity that has quite a large income. However, many farmers still use traditional concepts in determining which seeds to plant, such as trying out chili seeds without carrying out in-depth analysis or observation. A decision support system (DSS) is a system that is capable of providing decision recommendations using several criteria determined through method processes in the decision making system, namely ARAS, SAW, MOORA, AHP and others. The MOORA method is useful for separating the subjective part of an evaluation process into a decision weight criterion with several decision making attributes. And also the level of selectivity of this method is very good because it can determine objectives from conflicting criteria. Where the criteria can be profitable (benefit) or unprofitable (cost). Based on the results obtained after using the MOORA calculation method, there are 4 types of superior seed varieties that can be recommended for farmers, namely Taro Chili Seeds = 0.2875; Indrapura Chili Seeds = 0.2595 ; Lado Chili Seeds = 0.2490 ; Chili Seeds TM = 0.2154. By creating this decision support system, it is hoped that farmers will be able to use it as a reference in selecting superior chili seeds and be able to get maximum harvest results and increase commodity income for chili farmers.

Abstract

Implementation of snort as a wireless network security detection tool using linux ubuntu by adding a server that is used to observe activities on a wireless network, if there is an activity that is considered dangerous by the client, the information will be stored in the snort log and database. The web-based front-end uses BASE (Basic Analysis and Security Engine) which can be accessed through a browser with the url : IPaddressServer/base/. The information provided is related to attacks detected by snort that have been stored in the database. The information is in the form of source and destination IP addresses, the type of attack that occurred. Based on the tests carried out, it was found that the implementation of snort as a wireless network security detection tool using linux ubuntu can help detect attacks that occur on the network and provide information related to these attacks.
