Abstract

Small Office/Home Office (SOHO) is a term that refers to a small business or small-scale office. The network infrastructure in SOHO generally uses the default configuration from the manufacturer, such as active WPS mode and the use of the same key. Therefore, this final project implements Authentication, Authorization and Accounting (AAA) as a model for securing access on a SOHO network. The main perangkats in implementing AAA on a SOHO network are AAA servers and Wi-Fi Routers. The AAA server is the center for user authentication, setting access rights and monitoring user activity, while the Wi-Fi Router is used as a servis provider for Wi-Fi access and DHCP server. To support the implementation of AAA on SOHO networks, especially Wi-Fi access serviss, it is necessary to implement WPA Enterprise. WPA Enterprise requires a centralized authentication perangkat called the Radius server which is a servis on AAA. In this final project, we have successfully implemented AAA on an example of a SOHO network infrastructure. The latensi test for the authentication process on Windows perangkats is 170.750 ms and Android is 753.434 ms. The implementation of sharing users in grups with different access rights is gruped into 3 grups (IT, Management, and Sales). The three grups have different access times during weekdays and weekends. AAA servers can also log log-in and log-out activities as well as the duration of time a user is connected to the SOHO network.

Abstract

Nodes that have mobile properties form a network called MANET. This study uses protocol routing that is reactive, namely Location Aided Routing (LAR) where the protocol routing uses the position information of each node that comes from the Global Positioning System (GPS). From the use of these techniques and position information, the area to search for routes is reduced and restricted. Along with this, the energy consumed by each node needs to be reviewed. The performance of the Location Aided Routing (LAR) routing protocol can be affected by node movement. This movement node can pose a risk of disconnection between nodes and routing unsuccessful. The performance of the protocol is routing directly proportional to energy consumption. This study uses the number of different nodes and node movements to conduct test scenarios. In the 30 node scenario, the largest total energy consumption occurs in the movement model the Random Waypoint node and has a difference with the total energy consumption of the Random Direction node movement model of 351.491386 Joules. Conversely, in the scenario 45 and 60 nodes the largest total dominant energy consumption is when employing the Random Direction node movement model. In the Random Waypoint node movement model, the average energy consumption scenario decreases and increases regarding node addition. Whereas in Random Direction, the average energy consumption continues to increase. The amount of energy consumption is affected by the number of nodes and the different node movement models.

Abstract

Wireless Sensor Network (WSN) is a technology concept that uses a number of nodes that have processing capabilities to achieve or complete certain tasks. In general, wireless sensor network architecture requires an embedded system or embedded sensor that is able to connect to the network and communicate through the cloud server. One of the devices commonly used in the WSN architecture is the NRF24L01 module which is a communication module based on a single frequency radio wave band. The use of a single frequency for sending and receiving data allows the transmission signal to collide with the receiving signal which causes data packets to be lost or damaged. This can be avoided by using the method of scheduling sending and receiving data. One of the scheduling methods that can be used is the Time Division Duplex (TDD) method. The concept of TDD is to give a time slot at one processing time, where the process of sending and receiving data occurs in the same frequency as each processing time. This process has a time guard that is between the time of sending data and receiving data which functions to prevent collisions between sending and receiving signals. Previous research has succeeded in implementing the TDD method on the system of sending and receiving data using Bluetooth low energy and Wi-Fi in the plant monitoring system. The test of this research is done by testing scenario of sending data based on distance variation with two parameters, namely success ratio and average delay in sending data. The distance variation used in the study is 1 meter to 10 meters. The success ratio parameter produces the lowest success ratio value of 71% at a distance of 7 meters and the highest ratio of 91% at a distance of 5 meters. Then on the average delay parameter, the delay results are 0.871 seconds on sensor node 1, 0.638 seconds on sensor node 2, and 0.644 seconds on sensor node 3.

Abstract

Indonesia, which has a tropical climate, gets sunshine all year round. It is very useful for people to dry household or industrial needs. Examples of industries that use sunlight are the production of crackers, salted fish, coffee, and unhulled rice and others. However, apart from getting the continuous heat of the sun, there is also rain that is present erratically. So leaving things outdoors will be risky, especially during the rainy season. Therefore, the researchers created a sun dry system that can be put outside automatically when the outdoor conditions are sunny and there is no rain, and inserted when the outdoor conditions are rainy or there is no sunlight. These conditions will be taken using a raindrop sensor and a light dependent resistor sensor. Arduino Nano as a microcontroller used to control sensors and actuators. To control the system using the K-Nearest Neighbors method. After testing, obtained good results. The best value of accuracy and computation time in using the K-Nearest Neighbors method is at k=3 with the average accuracy of 98% and the computation time is 37.173 microseconds. When compared with the if-else method, the if-else method has an accuracy value of 100% and a computation time of 13.232 microseconds. The K-Nearest Neighbor method is feasible to implement in this system, but a simple if-else method is more profitable due to better accuracy and simpler source code.

Abstract

Parking is a process for every vehicle that stops at a certain place. Parking areas owned by agencies, institutions, and institutions should prioritize service and security for the sake of parking eligibility. The parking system that has been implemented so far is still being implemented with limited number of human guards, so it has many loopholes for theft to occur without the vehicle owner knowing. RFID technology is a solution for today in solving the problem of theft and contactless technology. Several studies have been conducted, many of which are used only as a parking area monitoring tool. The lack of a system/tool that is usually used to respond when a vehicle is lost belonging to a parking area user is a problem for both the parking area owner and the vehicle owner. This security system is made using RFID technology, Load-Cell sensors, and GSM modules as a solution to related problems. From the manufacture of the system, of course, it is necessary to test the problem of delay or response speed when a theft occurs. The results of the tests and analyzes carried out get pretty good numbers, namely around 2 seconds to provide notification in the form of SMS to vehicle owners, and about 5 seconds for the system to close the portal when it is open. The response given is the result of data transactions from the sensor node to the Gatekeeper node using the ESP-NOW protocol communication. The Gatekeeper node is also used to communicate with the basis data, in terms of verifying whether the user is registered or not. Registered user data will of course be recorded when accessing the parking area when entering or exiting and displayed on a web page.

Abstract

The Soekarno-Hatta Airport Class I Aviation Health Office (AHO) is a government institution tasked with validating COVID-19 negative test result (CNTR) documents, which is one of the prerequisites for boarding a flight. At one point, there have been forgeries made to such documents, which passed the manual and offline validation process done by AHO. To solve this problem, the writer try to devise an Information System for Verification of Swab Test Result Authenticity, which performs the validation automatically and online, so that flying can be safer from the risk of COVID-19 spread. The system was built by using the prototype development method, which consists of several stages, including data collection, requirements analysis, prototype building, prototype evaluation, system design, system implementation and system testing. Based on iterations done, there were 13 requirements identified from 2 actors, COVID-19 testing labs, AHO and system admin. Implementation was done using the javascript programming framework ReactJS and NodeJS. System testing was divided into four stages which consist of unit testing with 3 samples, integration testing to produce valid results, validation testing to obtain valid results from test cases, and non-functional testing in the form of usability testing using the System Usability Scale (SUS) method that obtained a point of 73,46 from 15 respondents.
