Abstract

It is important for doctors to make an early diagnosis of tuberculosis in order to reduce the transmission of the disease to the wider community. In this study, the authors will apply methods of data mining classification, Naïve Bayes to diagnose tuberculosis disease. Based on the performance measurement results of the models using Cross Validation, Confusion Matrix and ROC Curve methods, it is known that Naïve Bayes method with accuracy of 94.18% and under the curva (AUC) value of 0.97. This shows that the models that are produced including the category of classification is very good because it has an AUC value between 0.90-1.00.

Abstract

Electronic equipment is a daily necessity in human life, but not infrequently we use electronic equipment excessively or ineffectively and the main problem is the factor of forgetting and being lazy to turn off electronic equipment. This makes wasteful use of electricity so that the costs charged are greater and there is the greatest risk of contact currents causing fire if we neglect to use lighting. Therefore, the author tries to make a control device for electronic equipment with voice commands connected to Bluetooth on a smartphone so that users can give commands to activate or deactivate electronic equipment with voice commands. The research method used is direct observation of the selected object, namely the author's house, and conducting literature studies related to the Arduino microcontroller. The Arduino microcontroller acts as the main controller connected to the relay module and the relay module connected to the power plug. In addition, Arduino is also connected to Bluetooth as a place to process incoming commands. The purpose of this research is to produce a tool that can make it easier to turn on or turn off electronic equipment with voice commands via an Android smartphone by utilizing an Arduino-based Bluetooth connection.

Abstract

Water is an important need for all living things, especially humans. Humans need water with quality that meets the physical, microbiological, chemical, and radiological requirements contained in the mandatory and additional parameters. The selection of these parameters is very important to meet the requirements of good water, namely tasteless, odorless, and colorless. Meanwhile, there are three parameters used for water identification, namely pH parameters, turbidity levels, and temperature parameters. From these problems, the authors examine the detection of water quality, especially water turbidity. The author tries to make a tool that can detect the level of turbidity of water with a turbidity sensor as a detector of the level of turbidity in the water, Arduino Uno as a processor for the data results that have been detected, and a 16x2 LCD as a display of turbidity level measurement results in the form of turbidity values ​​and descriptions of the water being tested. The measurement range that can be detected by this tool is from 0 – 3000 NTU. The research method used is direct observation of the selected object, namely the author's home environment, and conducting library research related to the Arduino microcontroller. The purpose of this study was to determine and detect the level of water quality in the community. As one of the tools or alternatives for the community to find out or detect the level of water quality early.

Abstract

Home security is something that must be considered for every homeowner. Especially when you have to leave the house empty for work or even on vacation. You must be worried about thieves, lost jewelry, or the safety of other valuables. Therefore, the authors made a door lock security device by utilizing a Bluetooth connection with the Arduino Uno microcontroller. The research method used was direct observation of the selected object, namely the author's house, and conducting literature studies related to the Arduino Uno microcontroller. This door lock tool uses the Arduino Uno as a data processing center, because it is easy to use, and most importantly in the charging program, it does not require a download like a microcontroller in general. This Arduino Uno contains a special program that will give commands to the Servo Motor to open and open the door. Not only opening and opening doors, but this tool can also move the door without us holding or touching it but through a Smartphone. The purpose of this research is to produce a tool that can make it easier to manage or open doors using the Arduino via an Android smartphone using a Bluetooth connection.

Abstract

The advancement of science and robotics technology has made human life faster and easier. The field of robotics now encompasses all sectors, including industry, mechanics, and household. Therefore, a floor vacuum robot is needed to facilitate home cleaning. This research discusses a vacuum robot that uses Arduino Uno, ultrasonic sensors, and Bluetooth serial to operate the robot. This vacuum robot moves automatically using ultrasonic sensors that move forward while avoiding obstacles such as walls, which act as distance detectors. This allows the robot to automatically turn and avoid obstacles, continuing the cleaning process. Meanwhile, the Bluetooth system can also be manually controlled via a smartphone, allowing it to move forward, backward, turn, and stop. With a DC motor, you can manually operate the vacuum cleaner by pressing the on/off button located on the body of the robot. This robot makes household chores easier to accomplish.

Abstract

Dalam perkembangan teknologi yang semakin pesat, penggunaan alat yang dapat membantu pekerjaan manusia menjadi lebih mudah.Penggunaansensor yang kemudian diolah oleh mikrokontroler menjadikan sebuah alat dapat dimanfaatkan menjadi suatu alat bantu dalam kegiatan manusia sehari-hari. Penggunaan sensor ultrasonic berbasis mikrokontroler atmega16 dapat dijadikan sebagai pembaca mengenai suatu keadaan di depannya. Pemanfaatan alat ini dapat diaplikasikan dalam membuka sebuah portal atau haling pintu secara otomatis, yang akan membaca adanya suatu objek pada tempat dan jarak yang ditentukan. Sensor yang digunakan Pembuka Portal Otomatis akan membaca adanya halangan didepan, sehingga pada saat sensor membaca adanya halangan tersebut pada tempat yang telah ditentukan, maka portal akan otomatis terbuka. Begitupun sebaliknya ketika objek sudah tidak berada pada area lorong, maka Portal akan menutup dengan sendirinya

Unauthorized access to this system can lead to data breaches, grade manipulation, and loss of information integrity. This research aims to develop an early detection model for unauthorized access using machine learning algorithms. The methodology includes collecting and preprocessing SIAKAD access log data, extracting behavioral features (login frequency, access time, IP address, and activity patterns), and training classification models using Random Forest and Support Vector Machine (SVM) algorithms. Evaluation metrics used are accuracy, precision, recall, and F1-score. Experimental results show that the Random Forest algorithm achieved the highest accuracy of 97.3%, outperforming SVM (93.8%) in detecting anomalous access attempts. The proposed model can identify suspicious login activities in real-time, providing an additional security layer for SIAKAD IAI Al-Ghurabaa. The study demonstrates that machine learning-based intrusion detection is effective in enhancing system resilience against authentication-based attacks and user account misuse.Keywords: SIAKAD; data security; anomaly detection; machine learning; Random Forest; SVM;
