Abstract

One of the efforts made to suppress the spread of the corona virus in crowded places such as cafes is by checking body temperature and limiting the number of visitors according to PPKM regulations in the Java-Bali area. However, the body temperature parameter is not accurate enough to detect suspected Covid-19 symptoms and the calculation of visitor capacity is still not effective, which is still done manually. In addition, control over the cafe entrance is also needed considering the number of visitors coming or going. This study aims to develop a Covid-19 symptom measurement system using three parameters, namely body temperature, blood oxygen saturation and respiratory frequency using the Support Vector Machine (SVM) method to classify visitors into healthy and symptomatic classes. The system also provides output in the form of sound, information on the number of visitor capacities, and the application of miniature doorstops using a servo motor that moves according to the classification results. Tests of each sensor resulted in a very good average accuracy. The measurement of body temperature with the MLX90614 sensor is 99.26%, the measurement of oxygen saturation with the MAX30100 sensor is 98.95, the breath frequency measurement with the sound sensor reaches 100%, and the visitor capacity counter with the PIR sensor is 100%. Classification using the SVM method produces an average accuracy of 100% with an average computation time of 131.6 s. In addition, the output in the form of sound and movement from the miniature doorstop can work as expected.

Abstract

One of the efforts to realize a clean and good government is by reporting the performance accountability of government agencies. The report was also carried out at the Faculty of Computer Science, Universitas Brawijaya. The Quality Assurance Group of the Faculty of Computer Science has the responsibility for making the report. The quality assurance team had many problems when making the report. At this time for the manufacture of the report is done using Microsoft Excel with more than 40 sheets. It is not surprising that when the data processing is carried out errors occur such as entering the wrong data or accidentally deleting data. In addition, it is necessary to carry out data processing to find out that the data entered has met the achievement target or not. The current data collection is still done manually by taking data from several fields, so if there is a change in the data from these fields, it is necessary to re-collect the data. Therefore, the authors conducted research by developing an application of a government agency performance accountability system at the scope of the computer science faculty to assist the quality assurance group in preparing government agency performance reports. Website-based applications. The application development method used is the waterfall. This method is very suitable to be used when developing applications whose needs are clear.

Abstract

The transporter robot is one of the uses of wheeled robots to help activities in the industrial world. The use of robots carrying goods in the industrial world, especially in the logistics industry, is very much needed because robots can move and sort goods quickly and accurately and compete in warehouse automation to remain competitive and reduce costs. The design of the cargo carrier robot in this study will be based on a line follower robot that can read a Quick Response (QR) code. This system will be built using an Arduino Mega 2560 microcontroller as the main control with input coming from the gm66 sensor as a QR code reading contained in an object that is useful for determining the path planning chosen by the robot in deciding the direction to achieve the goal and the HYS301 line sensor as line detection on the track. This system uses PID control to stabilize the robot's motion when moving on a line and uses a path planning algorithm to determine the direction to be traversed by the robot. The test results on the gm66 sensor show that the ideal distance of sensor reading is at a minimum distance of 15cm, while the optimal reading distance for the HYS301 line sensor is at a distance of 3mm from the floor surface. The PID parameter values ​​obtained so the robot can move in a straight line are Kp = 3, Kd = 0.5, and Ki = 0.7. The time it takes to reach the rise time is around 0.2 seconds, and the time it takes to reach the settling time is 0.69 seconds. The path planning algorithm used is the same as the direction of the robot's motion when it is run. The accuracy results when using the first, second, and third path planning from the tests carried out have a value of 100% each.

Abstract

Micro Air Vehicle Link or commonly called MAVLink is a communication protocol for UAVs. A document, namely ISO 12100 and ISO 13849 summarized by (Allouch, et al., 2019) states that the MAVLink protocol is a UAV communication protocol that is vulnerable to attacks. The MAVLink protocol vulnerability is known because it does not have a security system support from the confidentiality aspect. To reduce this security risk, it is necessary to make efforts to secure the MAVLink protocol using cryptographic methods to ensure the security of the aspects mentioned above. In this study the Grain-128 cryptographic algorithm was chosen because of its ability to work on low-power devices. In addition to the implementation of the Grain-128 cryptographic algorithm, a security strategy is also implemented, one of which is the IV update system. The purpose of implementing the Grain-128 algorithm and its security strategy is to provide adequate protection for data on the MAVLink protocol. Thus the MAVLink protocol that has been implemented by the security system is resistant to passive attacks and even active attacks.

Abstract

SSS Snack Agent is a small business engaged in the wholesale trade of snacks and beverages. Currently, the recording of inventory and sales transactions is still done manually, resulting in limited access to information and the risk of miscalculation or recording. In addition, checking expired goods is quite difficult for employees because there is no record of the expiration date of goods when received from distributors. In response to these problems, the solution offered is to develop an inventory information system and sales transactions to make it easier for employees to solve problems related to recording inventory and sales transactions, as well as checking expired goods. The system will be developed with a waterfall on a web system with codeigniter framework based on the PHP programming language. The steps taken include needs analysis, design, implementation, and testing. The results of the validation test get 100% valid results from 11 test cases. For the results of the user acceptance testing (UAT), the test was carried out on three actors. First, the owner actor with a UAT percentage value of 81%; second, the cashier actor with a UAT percentage value of 82.5%; and finally, the warehouse staff actor with a UAT percentage value of 84%.
