Abstract

Car sales represent a business sector highly dependent on the implementation of appropriate payment strategies to enhance customer satisfaction and operational efficiency. This study aims to classify payment patterns in Toyota car sales using the Decision Tree algorithm. Historical sales data were utilized to identify various attributes influencing payment methods, such as cash, credit, or leasing.Through processes of preprocessing, feature selection, and model training, the Decision Tree algorithm successfully established clear classification patterns based on variables such as payment type, gender, car type, and car category. The research findings indicate that the Decision Tree method not only provides a high level of accuracy in classifying payment patterns but also produces models that are easily interpretable by business decision-makers. Thus, the implementation of this classification technique is expected to assist companies in designing more effective and targeted sales and promotional strategies.

Abstract

Perkembangan teknologi informasi pada era modern dan masa pandemi covid-19 ini memerlukan jaringan komputer yang memadai dan terjaga keamanannya. Penerapan Virtual Private Network (VPN) digunakan untuk pada jaringan komputer yang melakukkan transaksi data yang telah dienkripsi antar pengguna. Keamanan jaringan harus dijadikan prioritas utama dalam menghadapi serangan yang mungkin terjadi pada suatu jaringan komputer. Beberapa serangan yang umum terjadi seperti Denial of Service (DoS), Spoofing, Sniffing, dan lain sebagainya. Penelitian ini akan menerapkan VPN Tunnel untuk mencegah Packet Sniffing dengan metode LP2TP/IPSec. Untuk mengamankan paket data yang dikirim digunakan IPSec, sedangkan dengan IPSec VPN proses pengiriman data akan lebih aman tanpa adanya gangguan karena data yang telah dikirim telah dienkripsi dengan baik

Abstract

Motorcycle theft is getting more disturbing, so it encourages the author to make security devices on motorbikes. This study has created a security system that can secure motorcycles using an e-SIM based on the Atmega-8 Microcontroller. Where the e-SIM has a chip, the chip itself has 7 bytes. In this case, the authors take advantage of the 7-byte chip in the e-SIM. The e-SIM will replace the motorcycle ignition key. Not only that, but the e-SIM will also give orders to the motor starter to start the motorcycle. Thus, only the owner of the e-SIM who already has a sim can give the motorcycle ON and OFF orders. The research method used is direct observation of the selected object, namely the author's home environment, and conducting literature studies related to the Atmega-8 microcontroller. This study aims to create a security system for motorcycle vehicles to avoid theft and the use of motorcycles for children without driving licenses.

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 kehidupan, banyak hal dilakukan di dalam dan di luar ruangan, bahkan kegiatan tersebut tidak terlepas dari keberadaan pintu dimana kita harus membuka atau menutup pintu yang membuat kita merasa enggan melakukannya, secara berulang masuk dan keluar pintu dengan menarik atau mendorong pintu. Melihat kondisi bahwa sebagian besar proses operasi pintu garasi mobil masih dilakukan secara manual di mana intervensi manusia masih terlibat secara langsung, maka akan lebih praktis dan efisien jika pintu garasi dapat membuka sendiri. Oleh karena itu, semakin kompleks proses yang harus diatasi, semakin penting penggunaan sistem minimum ATMega16 untuk memfasilitasi proses tersebut, oleh karena itu penulis terinspirasi untuk membuat Merancang dan Membangun Pengendalian Pintu Mobil Menggunakan Sensor Reed Switch dan Mikrokontroler Berbasis RFID ATMega16. Alat ini berfungsi untuk secara otomatis membuka dan menutup pagar dengan input sensor yang terperinci. Jika kendaraan memiliki pengirim, secara otomatis sistem minimum akan menerima gangguan dari sensor dan akan memberi perintah atau melanjutkan membuka pagar secara otomatis.

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.
