Abstract

Lora is one of the Low Power Wide Area (LPWA) networks that allows a device that has a small amount of energy to be distributed over a large area so as to create a network that is interconnected with each other. One of the challenges in LoRa is the packet payload capacity that is sent through this protocol. The LoRa protocol has a packet payload capacity of between 51 byte and 222 byte, so it has limitations in sending data with large file sizes such as image data. From this explanation, this research focuses on implementing a data splitting mechanism to overcome these deficiencies. In this study, the image data splitting process will be carried out in the end node, then the image data fragments will be merged back inside the gateway and the image will be displayed through the server. The test results obtained from the largest latency which is at a distance of 100 meters by 10 seconds, while the lowest latency is at a distance of 10 meters by 1 second. In addition to the latency measurement, there is a success ratio measurement for sending data fragments that produces a maksimal value of 100% and the lowest value of 20% at a distance of 100 meters. In addition, there is an RSSI measurement that is measured and produces the lowest value of -88 dbm and the highest -112 dbm.

Abstract

Indonesian passports work as identification or identity of Indonesian citizens abroad. Therefore Indonesian citizens who wish to visit abroad for tourism, service or diplomatic activities must have a passport. Applications for passport are generally submitted to the nearest Immigration Office / Passport Service Unit through the Online Passport Service application. With this application, the application queue process should be easy to do. But in fact, many complaints against the application found. App ratings indicate that the current app was unhelpful. In addition, there are several requirements for passport applicants that have not yet been applied to the queue application that is currently used. The design and implementation of a website-based passport application queue system is builded using the user centered design method. The user centered design method applied so that the resulting system can be more accepted and easier to use by passport applicants because system users have diverse demographic backgrounds. By applying the UCD method to the passport application queue system, the usability value is quite high (good). The average value generated by the PSSUQ questionnaire method obtained a value of 1.03 for the System usefulness criteria, 1.28 for the Information quality criteria, 1.40 for the Interface quality criteria and 1.20 for the Overall satisfaction category. The PSSUQ questionnaire has the principle that the smaller the value (closer to 1), the higher the usability value, so it can be concluded that this system is acceptable and easy to use by users.

Abstract

Development of research in footsteps has been carried out, especially by using IMU sensor. IMU sensor is a system that can detect changes in speed, orientation of the gravitational force. However, the accuracy in measuring "footsteps" using IMU sensor is not yet accurate, due to inconsistent human footsteps, different body shapes, stepping models and so on. In this research, researchers used MPU6050 sensor where the sensor produces two types of sensors, namely accelerometer sensors and gyroscope sensors. Sensor placement points are located on the wrist, calf and thigh. Sensor used will produce three axis, where each axis is filtered using a Kalman Filter and a Finite Impulse Response (FIR) Filter. After the data is filtered, then data will be classified with the data has been sorted (training data). The classification used is K-NN and Naive Bayes. The use of the best filter is owned by the Kalman filter, which has the lowest average ratio compared to the FIR filter, which is 0.378. Accuracy results obtained from research that has been carried out are 92.5%, where the accuracy has a combination of the use of gyroscope sensors, sensor placement in the calves, the use of Kalman filters and the Naive Bayes classification algorithm. The resulting computation time is 0.23 seconds.

Abstract

The rise of Covid-19 cases that occurred in Indonesia from 2019 harmed all existing sectors. This has resulted in micro-entrepreneurs having to accept the uncertainty of when their business will return to normal. Assri store which are included in micro, small and medium enterprises (MSMEs) are certainly required to be more optimal, both in terms of quality and service. The development of information technology that has existed until now is a factor in the emergence of innovative applications that can facilitate work and also people's daily activities. It was found that there were deficiencies in the current system, namely the Assri store using a standard cash register to support sales transactions and the Olsera POS system. However, the POS system does not support online delivery and customer satisfaction information management features. Apart from features, the easy-to-use interface also supports users to be comfortable using the application for a long time. From the existing problems, it is necessary to design the user experience for the Assri store application. This design uses the HCD method which focuses on what is needed by the user. After designing the solution design, usability evaluation was also carried out using the scenario task method and the SUS questionnaire to 6 evaluators. From the results of the buyer's evaluation, the usability evaluation value obtained is 83.86% and is included in category A (excellent).

Abstract

The nose is an important organ in life for humans. In the nose there is a disease that causes the sinus wall to experience inflammation commonly known as sinusitis. Smoking habits, environmental pollution and cold air become other factors that can affect the onset of sinusitis. If sinusitis is not immediately treated and treated properly, it can lead to complications which then lead to infection. So it is necessary to do an initial check to detect sinusitis using Magnetic Resonance Imaging (MRI). In addition, the cost is quite expensive and a long period of time is the basis of this research. Therefore, a tool is needed that can detect sinusitis early. This research will use the MLX90614 sensor for body temperature feature extraction and the TCS3200 sensor for color feature extraction. The two features then be processed by Arduino Uno to carry out the classification process into two classes, namely the Normal class and the Sinusitis class. The classification process in this study uses the Support Vector Machine method. The results of the accuracy of the SVM classification get 85% of the 20 data tested. For testing the computational time obtained an average value of 42 milliseconds from as many as 20 test data used.

Abstract

Security on a local area network (LAN) is very important to note. Firewall as a security device of the network in general is not fully able to detect suspicious activities (malicious activities) on the LAN. One method that can be used to indicate the presence of malicious activities is to take advantage of the detection of the number of ARP Broadcast Request activities on the LAN. In this final project, the system is built to identify the presence of malicious host activity on a LAN by identifying and visualizing the ARP Broadcast Request data. The main components of this system are network devices, servers, and hosts. The process carried out for identification is to collect data, process data, visualize data, and upload the results of the visualization to the web. The ARP Broadcast Request data is transformed and represented into a graph in the form of nodes and edges which are then processed through clustering and filtering based on edge weight, weight-out degree node, and out-degree node to determine the IP address indicated as malicious host activity. The system has been made to identify nodes indicated as malicious hosts. Nodes identified as malicious hosts have many edges and are visualized with a larger size and redder color when compared to other nodes. The execution time required in the data processing stage ranges from 5 seconds to 7 seconds with a data retrieval duration of 58 minutes.
