Abstract

SMA Brawijaya Smart School (SMA BSS) is a state senior high school led by Brawijaya University. Student admission is one of the main activities at SMA BSS. However, in practice there are problems that hampered SMA BSS's student admission activities. Recapitulation of the student applicant is done with checking student's data one by one and it takes a lot of time. Error input in the online form filled by applicants also makes recapitulation process longer because examiner have to fix data layout for the better recapitulation process. In addition, student data is stored in several different places, causing data inconsistencies. To overcome that problem, writer developed student admission management system with functional features such as sign up, applicant's account management, computer based test, and mutation management. This system will be developed using waterfall model and will be implemented in web technology. This research generates 57 functional requirements and a non-functional requirement that system needs, system implemented in .NET framework with Model-View-Controller template using C# programming language, SQL server 2017, and IIS as web server. Based on unit and integration testing, component-component in the system can properly work and returning value as expected. Validation test resulted 100% valid from all test case based on functional needs and their alternative. Compatibility test with cross browser testing using SortSite is concluded that system can run well without losing it's functionality as well as no critical problems so it fulfills compatibility aspect.

Abstract

The large number of patients who do not have money so that they have to be treated outpatient causes new problems. The number of diseases caused by heart organs and human body temperature is an important problem. Based on the cases that have occurred, we need a system to monitor heart rate and body temperature. To solve this problem the design of the heart rate and body temperature was carried out using MQTT (Message Queuing Telemetry Transport) delivery. Heart rate reading uses a pulse oxymeter sensor by attaching the thumb to the sensor and the body temperature sensor LM35 by handheld. Data processing is done by using Wemos D1 and online storage namely cloud by utilizing the mqtt communication protocol. The process of displaying data is done in realtime. The test results on the two sensors give different results, namely 6.1 for heart rate sensors and 0.9 for body temperature sensors. Whereas for RTT (Round Trip Time) testing the system can complete less than 1 minute.

Abstract

Current technological developments, especially in the IT field have been developing very rapidly. Now, by using the internet, we can do anything even though we are far apart. One technology that utilizes the internet is a monitoring system or commonly called the Internet of Things. At present, the number of users of electricity is increasing from year to year. One of the services currently available is postpaid electricity service. However, in the distribution of electricity usage data is still done conventionally and data retrieval is done in an uncertain time span. From these problems, data collection and transmission can be carried out in a more efficient way by monitoring electricity usage in realtime on a publish-subscribe-based MQTT protocol. The monitoring system that is run has a small delay, which is 11 ms. In addition, the MQTT protocol can also be run on limited network conditions, namely on network conditions that have low bandwidth. At 32KBps the average delay is 17 ms. So the system can be run on a limited network.

Abstract

Delay Tolerant Network (DTN) is a network that uses a special architecture has been developed with effort to connect between devices that has high delay time used changing connection. Routing multi-copy is a routing that minimizing network delay and maximizing data transmission when compared to routing Single-Copy. However, the absence of buffer management causes ineffective use of buffers each node. First In-First Out (FIFO) and Most Forwarded First (MOFO) is buffer management that can manage buffers that existeach node. FIFO buffer management can manage buffers based on the time the packet was entered. Whereas MOFO buffer management manages buffers based on the number of packet forwarding. Based on routing performance testing, buffer management can optimize packet delivery on DTN. The simulation results show that the highest value of delivery probability is 0.4799 which is found in the management of FIFO buffer with buffer size of 12MB with Spray-and-Wait routing. The lowest overhead ratio value obtained is 14.4873 found in the MOFO buffer management with a buffer size of 12MB with Spray-and-Wait routing. The lowest latency average value is 2092.7180s found in Spray-and-Wait routing using FIFO buffer management with 5MB buffer size.

Abstract

The exchange of information via the internet is becoming the most effective medium today. Information connection via the internet Relating to an adequate internet connection. Some places that do not yet have adequate connectivity to the Kerinci mountain climbing route, make the transfer of information difficult because of high losses and large delays. Delay Tolerant Network (DTN) is a technology used on networks that are not always available. Using this type of multi-copy routing on DTN has advantages that can increase the delivery ratio and reduce the acquisition of this routing will require greater network resources. The buffer management policy can be used to optimize the use of limited buffers. Stationary Relay Node and Packet Priority can be used to increase the probability of sending messages. This research analyzes the performance of Multi-Copy routing with Shortest Life First buffer management, Packet Priority, and Stationary Relay Node supported using ONE simulator. Overhead Ratio, Delivery Probability and Average Latency in Spray and Wait, Epidemic and ProPHET routing. The results show the Spray and Wait for a route to get the best from the other route with an Overhead Ratio value of 5.0081, Delivery Probability of 0.9508 and an Average Latency of 1808.5116.

Abstract

VANET is a network that utilizes vehicles as nodes to exchange information and provides security and comfort for vehicle users. Its main characteristics are High Mobilility and Dynamic Network Topology. This characteristic allows data collision to occur, which is a condition where two or more nodes send data to the same destination at the same time. This situation causes the data transferred does not reach its destination so that the VANET function can be disrupted. Previous research stated that AODV is a better topology-based protocol compared to DSR and DSDV while GPCR is a position-based protocol with better performance than GPSR. This study presents an analysis of the effect of the two routing protocols on data collision and their performance analysis. Testing is based on changes in the number and speed of nodes with performance parameters throughput, packet delivery ratio (PDR), end-to-end delay, and collision rate. The results showed that the relationship between the two routing protocols to the collision rate was more dominantly affecting the results of the packet delivery ratio parameters. In performance analysis, AODV better at throughput and PDR with 48,05 kbps and 49,82 % while GPCR with 0,66 kbps and 7,3 % when there is a change in the number of nodes. When the node speed changes, throughput and PDR of AODV are 51,32 kbps and 33,34 % while GPCR are 0,585 kbps and 9,85 %. In end to end delay, GPCR is much better than AODV. On changes in the number and speed of nodes, each values ​​of AODV are 792.717 ms and 233.245 ms, and the values of GPCR are 14.528 ms and 5.252 ms.
