Abstract

Insomnia is a sleeping sickness in which the time and quality of human sleep is not sufficient due to difficulty getting to sleep or difficulty maintaining sleep. Early diagnosis and treatment of insomnia is necessary to prevent chronicity and death resulting from untreated insomnia. The body's required ECG signal can be detected by installing a sensor on the human body. The ECG signal has several points, namely P, Q, R, S and T points. There are PR intervals, PR segments, QRS complex, ST segments, and QT intervals as areas in the ECG signal. In this study, we will use the R-R interval of human ECG signals taken when the sleep condition is for 2 hours which already represents one person's sleep cycle. The features to be used are the Mean RR and SDNN features. The K-Nearest Neighbours method classifies new data by finding the shortest distance from the training data, this makes this method suitable for this study because the training data used has significant differences between one class and another class. The tools that will be used to detect insomnia are the Arduino Uno microcontroller and the AD8232 module which are used to detect and filter the detected signals. AD8232 is a module used to acquire ECG signals. The use of K-Nearest Neighbours as a classification method has an accuracy of 86% for K = 3 and obtain an average computation time of 79.9 ms.

Abstract

CV Wins Advertising is a printing company that was established in 2011 in Batu City. Currently, CV Wins Advertising carries out its business processes using conventional methods such as monitoring, recording orders, and submitting orders to the production department. This has the potential to cause problems, namely loss of order records and negligence of business processes. Therefore, digitization and good interaction design are needed for the digital solutions being developed. This study aims to design interactions with information systems supporting web-based printing business processes for the monitoring process, order recording, to delivery to the production department so that order records can be stored in a structured manner and minimize negligence in business processes. The design approach used is Human Centered Design (HCD). In this study, two types of designs were produced, namely high-fidelity prototypes on computers and mobile phones. The two types of design are evaluated by users using scenario-based usability testing on the Single Ease Question (SEQ) to measure the level of difficulty. The evaluation results show that the design is easy to use and resulted in several suggestions for improvement which include detailed reports, additional content requirements for employee presence, and additional requirements in the form of notifications.

Abstract

Mobile Ad-Hoc Network (MANET) is a wireless network that has several interconnected nodes and acts as a router to transmit data. Several nodes can interact with each other by implementing routing protocols, one of which is TORA. TORA has a control message in the form of UDP (Update) to update the routing table and a CRL (Clear) control message that can minimize the occurrence of continuous looping which results in data not reaching its destination. The minimization process is not said to be perfect if there are many additional nodes. Research needs to be done using other methods, namely manipulating control traffic on the network by adding attacks in the form of wormhole attacks. Wormhole has characteristics that are very likely to affect the environmental conditions of MANET using TORA. The characteristics possessed by Wormhole are 2 nodes that can be connected to each other and can send data even with a very far position so that it is likely to reduce the occurrence of looping during packet transmission. The test results are obtained based on the Packet Delivery Ratio, Packet Loss, Troughput, and End to End Delay test parameters. Overall, the application of wormhole in TORA produces better performance compared to not applying wormhole. Packet delivery ratio testing with a scenario of 20 nodes shows 90.56% results compared to only 79.64% without wormhole. Testing the average troughput with a scenario of 20 nodes shows results of 95.06kbps compared to only 83.6kbps without wormhole. And testing the average end to end delay with a scenario of as many as 20 nodes shows results of only 19.18ms compared to without a wormhole rising to 30.12ms.

Abstract

To determine the tempo in a song, Metronome is needed to help as a tool, because the metronome will produce sound on every beat of the song. However, the metronome used on the market is less effective in terms of helping the tempo during live shows and can also interfere with hearing when using earphones if the volume of the metronome should be increased. A metronome arm band can be a solution because it produces a vibration that can be felt in the hands. Users can also set the desired number of beats per minute (BPM) via a smartphone application that is connected via bluetooth. There are 3 elements to be used, which are; Smartphone as input, ESP32 as processor and Vibration Motor as an output. Because metronomes must have high accuracy in keeping the tempo, RTOS is needed to help avoid interruptions when the user sends other commands during vibration. There are 3 tests carried out to determine the accuracy of the Metronome Bracelet. The first test to see whether 60 bpm on the metronome produces an output of exactly 60 beats per minute. The second and third tests are also the same but at different tempo numbers, which are 90 and 120. The expected output of the metronome should be exactly like the number shown in the bpm value on the Metronome Bracelet, where 60 produces a vibration accuracy of 60 bpm, 90 produces 90 bpm, and 120 produces 120 bpm.

Abstract

Water is a very important natural resource for the survival of humans, one of which is as a source of consumption. The safety standards for drinking water established by the government are very important to ensure the safety of the drinking water we consume. To be safe for health, drinking water must meet physical, microbiological, chemical, and radioactive requirements. However, there are still some areas in Indonesia that face difficulties in ensuring the safety of the drinking water they consume. From this problem, researchers want to make a drinking water quality detection system that can provide information related to pH and water clarity to users. The drinking water quality detection system is made using the pH-4502C and turbidity SEN0189 sensors and the Arduino UNO microcontroller connected to the 16x2 LCD as an information display. The results of the two sensors will then be classified using the Naive Bayes method. In this study, sensor testing and method testing have been conducted. The results obtained in the pH-4502 accuracy test are 96.54%. Then, based on the results of the SEN0189 turbidity sensor test, it can be seen that the SEN0189 turbidity sensor can work well in reading the condition of water being cloudy or not. From the readings taken on drinking water (clear) and coffee water (cloudy), it can be seen that the voltage values produced by the sensor are different. A higher voltage value indicates that the water is clearer, while a lower voltage value indicates that the water is cloudier. In the Naive Bayes accuracy test, the result obtained is 100% of 15 total test data and 30 training data. The data is in the form of drinking water in a public environment.
