Abstract

Discipline is important aspect in education. Sanctions can be educational tool to penalize student disciplinary. The unavailability of facilities to search for violators data and the accuracy of the data is in doubt. FILKOM of Brawijaya University have constraints filling record of student violation because history files student violation difficult to find. Based on the problem, author want to make application for help FILKOM managing history files student violation. The system development uses the waterfall Life Cycle Software (SDLC) waterfall with an object oriented approach. In the analysis phase, the authors applied the use case diagram and use case scenario. The design phase is done by creating sequence diagrams, class diagrams, entity relationship diagrams, and mocups. At the implementation stage, the authors use Laravel as a framework and MySQL as a database. After the implementation stage, application ready use with function can record violations of students with minor, moderate, severe violations and the application can also record book bills on violations that have a book fine. Testing on functional requirements uses unit testing and validation testing. The outcome shows 100% valid result on both tests. Testing for non-functional requirements uses browser compatibility testing. It shows that the system is compatible on Android, Chrome, Edge, Internet Explorer, Firefox, Opera, Safari and iPhone browsers.

Abstract

One of the dynamic routing protocols that are found on a computer network as well as being the focus of this research is Open Shortest Path First (OSPF). The application of the OSPF routing protocol can be adapted to the conditions of a network through area grouping i.e. single area and multi area. Multi area implementation can reduce the number of routes monitored, the dissemination of information becomes more orderly and segmented, reduce the calculation frequency of the routing algorithm, and reduces resource usage of the router devices that run it. Therefore, in this study used Graphical Network Simulator 3 (GNS-3) to simulate single area and multi area to find out which concept of area is the most optimal in a network condition using the OSPF routing protocol. The parameters used as the performance measurement of the routing protocols are time Convergence and roundtrip time. Roundtrip times of single area using the OSPF protocol have a value of 183.4 ms, while multi area consisting of 3 areas and 5 areas using the OSPF routing protocol have a round-trip time of 175.6 ms and 179.1 ms. The convergence time in single area using the OSPF protocol has a value of 44.6 seconds, while multi area consisting of 3 areas and 5 areas using the OSPF routing protocol have a convergence time of 43.6 seconds and 40.6 seconds.

Abstract

One type of Ad-hoc Network is Mobile Ad-hoc Network (MANET) is a collection of nodes that can move and communicate in a network. The move node causes the topology on the MANET network to change frequently. In addition, there is a possibility that nodes will move away from neighboring communication range. It can increase the risk of path failures for connection and impact network performance. The mobility model of one another can produce different results on each routing protocol. Testing is required to select the appropriate mobility models. This research uses the Dynamic MANET On Demand (DYMO) routing protocol and is applied with the mobility models of Random Waypoint (RWP) and Random Direction (RD). The research was conducted using Network Simulator 2.35 to perform the scenario of adding the number of nodes, the addition of the simulation area and the addition of maximum speed. The test parameters for each scenario are packet delivery ratio (PDR), end-to-end delay, throughput and packet loss. The effect of RD movement when testing the area, causes the width of the distance between nodes because the node moves to the edge of the simulation area so that packet loss is high compared to RWP where the distance between nodes is shorter because the movement is random in the middle of the simulation area. The results showed an average PDR value for RWP of 98.60% while RD was worth 96.16%. Then the average packet loss for RWP is 1.40%, while RD is worth 3.84%.

Abstract

Increased requests to fulfill the needs of the user in accessing the internet occur as technology develops. The increasing number of requests is also accompanied by a very high increase in traffic which can cause overload. Web server load balancing method which is implemented in the network architecture known as software defined network can be a solution to improve the performance of the server. Several previous studies had implemented web server load balancing using algorithms like round robin, response time, and server resource based algorithms such as CPU usage based algorithm which had different performances. Resources of a server such as memory can serve as a parameter in the load balancing algorithm. The server with the smallest memory usage will service requests which are requested by the client. Memory usage based algorithm uses psutil agent to find out memory information on the server and is implemented in POX controller. The result of this study is sending requests by clients to the server with the smallest memory usage. The memory usage based algorithm is compared with the CPU usage based algorithm in terms of parameters such as throughput, response time, and memory utilization. In testing with 1800 requests as the largest connection requests, the memory usage based algorithm has a higher throughput value of 29.44 KB/s compared to the CPU usage based algorithm, which is 27.78 KB/s. Meanwhile, the memory usage based algorithm has a lower response time value of 5.68 ms compared to the CPU usage based algorithm, which is 5.88 ms. At the server with the highest memory capacity, the memory usage based algorithm has a lower memory utilization value of 12.94% compared to the CPU usage based algorithm, which is 13.20%.

Abstract

Electricity is one of the necessities of human life. One of those that provide electricity services in Indonesia is a state-owned company, namely PLN. PLN itself has 2 categories of electricity customers, namely, prepaid and postpaid. Postpaid customers make bill payments according to the energy used for a period of 1 month. However, in reality in the field, according to the head of the daily management of YLKI (Indonesian Consumers Foundation), Tulus Abadi, PLN officials frequently record errors for postpaid customer electricity meters. The problem is that PLN is still monitoring customers manually for postpaid electricity. To overcome this, it is necessary to establish a kwh meter monitoring system for PLN customers. This monitoring system will send KWH usage data using the LoRa communication protocol which will then be sent through the gateway, then the data will be forwarded to the broker using the MQTT protocol and the data will be subscribed to by the client so that the data can be monitored regularly. In the research conducted, the author of this monitoring system has an average percentage of error data kwh of 0% and a wattage of 0.6% compared to other sensors KWE-PM01. For sending data from the sensor node to the client it can run well. At a distance of 100 meters to 300 meters, sending from the sensor node to the gateway is the best delivery in this study. Because the successful rate for testing single and multiple nodes at this distance, the packet can be received 100% by the gateway.

Abstract

Vehicular Ad-Hoc Network (VANET) is a network which the development is devoted for node in form of mobile vehicle. As the frequent changes of node compotition, it is required a routing protocol that functions to determine the proper information dispatch line between nodes. The obstacles that are often found in cities is the vehicle density, the signal transmition barrier such as concrete, buildings, as well as the interfention and varied movements of the node, therefore it is needed a proper routing protocol to maintain the data transfer efficiently. By analyzing the performance comparation of FSR and GPSR protocol, it was obtained a trial parameter in form of End-to-End Delay, Packet Delivery Ratio and Throughput so that it would be found which one is the most efficient protocol to be implemented in urban area. By the vehicle density scenario, it was found that the denser of the vehicle, the lower of the performance and trial score and it was increasing as the density of vehicle was decreased. FSR protocol has the Packet Delivery Ratio average rate for about 22.398%, End to End Delay for about 0.45s and Throughput for about 0.337kbps. Meanwhile, GPSR protocol has Packet Delivery Ratio average rate for about 25.493%, end to end delay for about 0.64s and throughput for about 0.480kbps. Based on parameter score tested, it was concluded that GPSR is better to be used in VANET in urban environment.

Abstract

MANET has 2 main types of routing protocols, namely reactive routing protocol and proactive routing protocol. One example of a reactive protocol is DSR (Dynamic Source Routing) and the proactive protocol is FSR (Fisheye State Routing). Mechanisms differ in communication, so the performance of the two routing protocols is different. The node route is so dynamic at any point in time, it can change and become one of the factors in the performance of the MANET routing protocol. In this study using DSR and FSR protocols because each type of routing protocol has a different algorithm significant impact on the performance of routing protocols in topology. MANET uses Network Simulator 2.35 with parameters End to End Delay, Routing Overhead, Packet Delivery Ratio and Thoughtput. The test scenario was carried out with variations in the number of nodes of 10, 25, 50, 75 and 100 nodes, and with variations in package sizes of 512, 1024 and 2048 bytes, and with speed variations of 5 m/s, 10 m/s and 15 m/s. The result is an average end-to-end delay based on the number of nodes, package size and node speed lower than the FSR protocol with an average value of 3.74 s, 5.32 s and 25.32 s. While with the average value of DSR protocol is 2.06 s, 3.08 s, and 72.27 s. For overhead routing tested based on number of nodes, package size and node speed are lower with an average value of 854.85 packets, 519.06 packages and 836.76 FSR protocol packages, while with an average value the DSR protocol is 61.02 packages, 36.15 packages and 153.6468 packages. Packet delivery ratio tested based on number of nodes, data package size and node speed are higher than FSR protocol with average values of 48%, 39% and 41%. While with the average value of DSR protocol is 94%, 95% and 92%. For throughput testing based on the number of nodes, package size and node speed is higher than the FSR protocol with an average value of 0.13 kbps, 0.20 kbps and 0.098 kbps while with an average value the DSR protocol is 0.23 kbps, 0.44 kbps and 0.87 kbps.
