Abstract

Communication is the most important part of everyday activities. In the current era, communication can be done in various ways. One of them is through electronic messages (E-mail). E-mail is a means of exchanging information through electronic communication by sending, receiving, changing and storing messages. Using e-mail is more practical than writing and sending letters manually. However, the use of email is also very vulnerable to crimes in electronic communication or the internet. Security and confidentiality issues are an important aspect of messages, data and information. This is related to the importance of messages and information sent and received by interested parties or people, whether the authenticity of the messages and information is still maintained or not. Therefore, security is needed to maintain the authenticity of messages or information from the contents of the e-mail using cryptography. Cryptography is the art and science of encryption that aims to maintain the security and confidentiality of data. In maintaining the confidentiality and security of electronic messages, the RSA (Revest Shamir Adleman) algorithm method is used, so that the confidentiality and security of the data or information can be maintained and RSA has security at the level of difficulty in factoring nonprime numbers. RSA has a key pair, namely a public key and a private key. This research produces an android application that aims to maintain the authenticity of message contents and information sent by means of messages that have been sent can only be read through the application. Messages sent through the application will also enter into Gmail's incoming contacts. But the user cannot read the message from Gmail because the contents of the message are encrypted and can only be read from the application. And users can only send messages to other users of the application.Keywords: Cryptography, RSA, Email, Android, Enkripsi. Deskripsi

Abstract

Internet is a necessity for the current era. The number of requests for internet access cause long response time and overload. Especially in offices that provide public services such as the Department of Library and Archives in Riau Province. To keep service work at the Soeman HS Regional Library not interrupted, so it will give comfortable for visitors, network optimization will be carried out with Load Balancing Technique. Load Balancing will balance load traffic on two or more connection lines, so that traffic can run optimally. The method used is Peer Connection Classifier, whereas this method will divide load based on sources, destination addresses and port addresses. All internet requests from users will go to Router that has been configured with PCC method, so on the Router will set up the exit request from user through ISP 1 line or ISP 2 line to be able to go to internet connections. The test results show that the equal distribution of outgoing access to ISP 1 and ISP 2 lines in a balanced manner, so there is no overload in any of ISP lines. The configuration will be applied in the Mikrotik Router using the Winbox application. Keywords : Load Balancing, Optimization, Peer Connection Classifier, Failover, ISP Lines.

Abstract

Fiber optic network (FO) is currently one of the telecommunications network transmissions widely used by operators to meet the needs of telecommunication services. FO is able to transmit data quickly. This is because the FO has a large bandwidth and has a small attenuation. Behind the advantages, the FO also has a disadvantage, namely the FO transmission does not always meet the damping standards provided by the operator. Such as fiber optic attenuation (attenuation loss), splice loss, connector attenuation (connector loss), bending loss, coupling loss and other attenuation. In general, operators use the single mode – single mode (SM) FO connection method. This research uses single mode – multi mode method. This research can help operators in performing maintenance and troubleshooting by analyzing power link bugdet on single mode – multi mode (MM) FO connection to improve FO network performance, so that operators can compete with other telecommunications service providers.Keywords : Power link budget, loss, single-mode, multy-mode, fiber optic

Abstract

The Information and Communication Technology Integrated Services Unit (UPT TIK) is an unit in the University of Riau which is engaged in the service and management of everything related to information technology. UPT TIK manages network devices such as routers and switches that are scattered in every faculty/ institution building in the University of Riau. Network administrator who monitors the network equipment. Currently, the monitoring process uses the Cisco switches at UPT TIK by checking the devices one by one. This monitoring process is deemed ineffective because there are many devices unmanagable scattered in every faculty/institution building at the University of Riau so that administrator have difficulty checking the state of the devices whether they are connected or not. In this study, the design and implementation of the SNMP protocol for network management was carried out directly at the UPT TIK University of Riau. A monitoring system can also be called a Network Management System, which is a system that functions to assist network administrator in monitoring and controlling network devices. SNMP is anapplication protocol on a TCP / IP network that can be used as a protocol in Network Management System. The development of this system uses the PHP Programming Language and the MySQL database management system. From the results of system testing and analysis, it is found that the monitoring and network management systems that have been designed can run well in monitoring network devices.

Abstract

Today, internet has become a part of everyday life for millennial society. An internet network addressing protocol is needed in order to connect one user to another user. Border Gateway Protocol (BGP) is a standard routing protocol offered to choose interdomain paths. The main function of BGP is to exchange network coverage information between BGP routers and other BGP routers. BGP is also divided into 2 types, the External Border Gateway Protocol (EBGP) and the Internal Border Gateway Protocol (IBGP). GNS3 is used to design and simulate modeling the BGP protocol and capturing the data packets using wireshark. The results obtained from the measurement of Quality of Service (QoS) for multimedia traffic in the EBGP and IBGP networks are 55 ms delay (EBGP) and 82.5 ms (IBGP) for audio streaming. Meanwhile the throughput value is 1.182 Mbit/sec (EBGP) and 0.591 Mbit/sec (IBGP) for audio streaming. These results show the good performance is reached because the result meet both ITU-T G.114 and ITU-T G.1010 standards, which is a good average delay for sending packet data is <150 ms and packet loss is <1%. Keywords : Network, EBGP, IBGP, QoS, Delay
