Abstract

Encryption is a solutions to secure the information transmitted through the medium of communication that can not be intercepted by unauthorized parties. This study implemented two algorithms i.e. RC4 and GGHN (8.8) in video conference. This study compared the speed  of  both  encryption  and  decryption  of  the  encryption  algorithm,  and  perform  measurements  of  bandwidth .  From  the  results  of measurements of the speed can be concluded that the RC4 algorithm is 1.53 times and 1.34 times faster than GGHN(8,8) for encryption and  decryption  audio  data.  The  encryption  and  decryption  video  data  RC4  are  1.44  times  and  1.09  times  faster  than  GHN(8,8). Bandwidth  usage  for  video  conferencing  without  encryption  and  bandwidth  usage  on  a  video  conference  with  RC4  encryption  and GGHN (8.8) is the same.Keywords: Video Conference; RC4; GGHN(8,8); Real Time Protocol.

Abstract

Tanaman stroberi memerlukan kondisi lingkungan tertentu agar dapat tumbuh dengan optimal, yakni suhu yang dingin dan lembab. Oleh karena itu, dibutuhkan sistem yang mampu mengontrol suhu, kelembaban udara, dan kelembaban tanah secara otomatis. Sistem ini memanfaatkan sensor kelembaban tanah (soil moisture sensor) untuk mengukur kelembaban tanah, serta sensor suhu DHT22 untuk mendeteksi suhu udara di dalam greenhouse. Data yang diperoleh dari sensor-sensor tersebut diolah oleh mikrokontroler ESP32, yang kemudian mengendalikan relay untuk menyalakan atau mematikan pompa air dan perangkat Peltier sesuai kebutuhan. Jika kelembaban tanah di bawah 40%, pompa air akan diaktifkan hingga kelembaban mencapai lebih dari 70%. Perangkat Peltier dan kipas akan dihidupkan untuk menurunkan suhu apabila suhu dalam greenhouse melebihi 28°C, dan akan dimatikan jika suhu turun di bawah 22°C. Sistem ini juga mengendalikan kipas tambahan untuk menjaga kelembaban udara agar tetap berada dalam rentang yang optimal.

Abstract

Katokkon pepper is a variety of South Sulawesi pepper, distinguished by its large size, bright red colour, and characteristic spicy flavor. Despite its high potential, the growth of catokkon peppers can be hampered by weather changes and environmental inadequacies. In an effort to boost the growth and yield of catokkon peanuts, the application of technology becomes an effective solution. Greenhouses, specialized buildings with materials like glass or plastic, can be ideal containers to tackle environmental problems. This greenhouse, connected to the Internet of Things (IoT) using ESP32 as a microcontroller, is capable of automatically controlling the temperature, humidity, and soil moisture according to the needs of catacombs. The implementation of this IoT technology provides practical solutions for farmers in the face of agricultural problems and improving the yield of catokkon peppers.

Abstract

Angkasa Pura II adalah perusahaan publik yang memiliki 100% saham dari pemerintah, sementara Japan Airport Terminal Co. adalah perusahaan swasta yang sahamnya diperdagangkan di Bursa Efek Jepang setelah Penawaran Saham Perdana (IPO). Analisis dilakukan dengan menghitung EBIT-EPS, yang menunjukkan hasil bahwa struktur modal harus dipilih untuk menghasilkan EPS yang lebih tinggi. Rasio utang-ekuitas perusahaan sangat tinggi, menunjukkan bahwa jumlah utang dalam struktur modal menunjukkan beban utang. Hal ini tidak baik untuk kekayaan pemilik dan mengakibatkan posisi likuiditas yang rendah. Ini mengurangi dana dan kepercayaan pemilik karena risiko pemegang saham meningkat dengan adanya peningkatan pinjaman, juga mengakibatkan nilai perusahaan dapat menurun. Hasil analisis menunjukkan, meskipun rasio utang baik, Angkasa Pura II (Persero) maupun Japan Airport Terminal Co. tidak menerbitkan saham tambahan. Ini merupakan keputusan yang tepat karena EBIT selama periode tersebut lebih tinggi daripada EBIT EPS sehingga perusahaan seharusnya memilih Utang untuk struktur modalnya.

Abstract

In modern times filled with technological advances, concerns about crime, especially the rise of theft cases, are increasing. Various methods are used by criminals to open the door of the house due to weaknesses in traditional security systems, such as door locks or padlocks. Therefore, a more sophisticated security solution is needed to protect the room in one way, namely the use of an automatic door security system with facial recognition as an exclusive method to grant access.Facial recognition as a biometric technology is considered an innovative solution in protecting access to rooms. The face recognition process involves face detection, feature extraction, and face recognition, forming a system that can accurately identify individuals. By using a camera as a sensor, users do not need to make physical contact, simply facing the camera to prove their identity. The main advantage of this system is its ability to reduce the risk of crime, as the room door will only open if the detected face has been registered in the system.This research has successfully built a reliable face recognition system for automatic doors by using Huskylens camera as a sensor, Solenoid as a door lock, and ESP32 as a microcontroller, this tool is expected to be an effective solution to improve room security. The main objective of the researcher is to successfully implement a facial recognition system that is accurate and provides proper access to entitled individuals, creating an additional layer of security without reliance on traditional physical locks.Keywords: Face Recognition, ESP32.

Abstract

This research focuses on developing an infusion fluid drip monitoring system prototype using Internet of Things (IoT) technology and Android device integration, which aims to increase efficiency and safety in managing intravenous fluids in medical units. So far, monitoring of infusion drops is still carried out manually by medical staff, In the meantime, the quality of infusion monitoring can affect the patient's condition and overall treatment results. the system consists of a liquid drop sensor connected to a microcontroller as a controller unit, with data sent via a wireless communication module to an IoT server. Users can access real-time information via an Android application that provides graphical displays of drip rate, infusion volume, and error warnings. Through simulation testing of clinical conditions, the results indicate that this system operates effectively and provide quick notification of significant changes in infusion fluids. This prototype can improve the efficiency of infusion fluid management, reduce the risk of dosing errors, and provide better monitoring of patient conditions in healthcare units. The possibility of integration with other technologies can also increase the functionality and security of these systems.Keywords: Infusion monitoring system, Internet of Things (IoT), Android, drip sensor, healthcare efficiency.

Abstract

A wheeled soccer robot is designed to move and kick the ball to score goals. This robot is equipped with wheels and motors for movement, a camera as its "eyes," and a servo motor for kicking the ball. One of the cameras that can be used is the HuskyLens, an artificial intelligence camera specifically developed for robotics applications. The use of HuskyLens in the soccer robot has the potential to change how the robot interacts with the ball, opponents, and its environment in a smarter and more adaptive way. The robot is designed to move and kick the ball automatically. Components used include an Arduino Uno microcontroller, HuskyLens camera, L293D motor driver shield, MG90S servo motor, proximity sensor, DC gearbox motor, and mecanum wheels. This research involved direct observation of several tests to evaluate the effectiveness of the components, particularly the HuskyLens camera, as the robot's "eyes." The results of the research and tests show that the robot successfully detects and approaches the ball to kick it. The camera can detect the ball at a distance of up to 12 meters, and the robot can kick the ball from a distance of up to 1.4 meters. Keywords : Robotics, huskylens, l293d motor driver shield, proximity sensor, Arduino Uno microcontroller.
