Muhammad Diky Darmawan — 2023-10-31

Abstract - Comfort in a room is able to provide relaxation for tired bodies from daily activities therefore using Smart Building Automatic System technology which can also be called a smart building is a design of construction and technology protection that is suitable for use to bring out all the functionality and comfort for residents with the aim of also reducing operational costs, and extending the life of the physical form. For the components that will be used, there is a connection through the local network that has been provided, so that it can be used for various things, one of which is used to monitor and monitor lighting control in a commercial building. This research will build a system using the Esp-32 which is used as a microcontroller, then to monitor temperature and humidity will use the Dht-11 sensor which is used to control the automatic blower system, and also use the LDR sensor module which is used as a light controller automatically and manually. , and all these results will be displayed on the Node Red dashboard which is the monitoring center. Because you could say that lighting is the largest source of energy used by humans, thus resulting in increased operational costs that must be incurred, especially if the use of this energy is not properly controlled.

Prototipe Sistem Monitoring Gangguan Motor Tiga Fasa Berbasis IoT

Emanuel Purwadi Wicaksono — 2023-11-04

-. In the industrial world, three-phase motors are widely used because they have simple construction, easy maintenance, constant rotation, cheap, high reliability and have a high power factor. However, when operating a three-phase motor, disturbances often occur such as voltage imbalance, current imbalance, excessive load, and even overheat. This research was carried out to produce a three-phase motor disturbance monitoring system that can be accessed via the web which is easy to access and has good accuracy values. The research method uses the ADDIE method with a quantitative approach. The average results of motor measurements using the PZEM004T sensor obtained a no-load voltage value of 220V – 223V with an error of 1.04% - 1.95%, a single phase voltage value of 217V – 224.4V with an error of 1.14% - 2, 5%, average current value of 2A – 4.2A with error of 0% - 16.6%, active power value of 144.6W – 790.4W. The results of motor temperature measurements using the LM35 sensor were 38 ºC - 50 ºC with an error value of 1.06% - 2.5%. The RPM measurement results using an optocoupler sensor were 1027 – 2375 with an error value of 0.26% - 58.71%. From the measurement results it is known that the no-load voltage and single phase voltage have good values, there is an imbalance in the current and power used, the motor temperature increases relatively significantly, and it has an unstable RPM.

Design and Analyze the Quality of Services (QoS) of a VoIP Server Using Briker by Utilizing Trunk and Interactive Voice Response (IVR) at the AirNav Padang

Muhammad Adibasyah — 2024-01-23

In the digital era, VoIP communication technology is popular due to its low cost and good voice
quality. At the AirNav Padang, communication is still manual using conventional telephones, which is
considered expensive and less effective. The solution is to implement VoIP through the local network, utilizing
computers, smartphones, headphones, and analog phones for cost efficiency and cross-division
communication. Similar research has addressed cost issues with VoIP. However, VoIP implementation
requires good Quality of Service (QoS) to avoid delays, jitter, and packet loss that can disrupt communication.
This research focuses on the design and analysis of QoS for a VoIP server with Briker, trunk, and IVR at the
Perum LPPNPI Padang Branch Subsidiary Office. QoS measurements show an average delay of around
22.754 ms, an average jitter of about 3.572 ms, and an average packet loss of about 0.04% for calls between
clients. Meanwhile, for calls with trunk and IVR, the average delay is approximately 21.756 ms, the average
jitter is around 5.402 ms, and the average packet loss is about 0.05%. This solution can optimize cross-division
communication with low costs and high efficiency.

Design of Electric Oven Temperature Control System Using PID Method

Muhammad Irsyad Awaludin — 2024-01-30

In a modern world filled with diverse kitchen needs, ovens have become an essential device to fulfill various cooking requirements. The availability of ovens of various sizes, operational power, and heat output is key to achieving optimal cooking results. However, temperature control in most ovens still relies on a simple on-off system, which may not be fully effective in maintaining a stable and accurate temperature. Therefore, an innovative approach is needed to improve the oven's performance, particularly in achieving and maintaining the temperature desired by the user. This research is based on the implementation of the PID (Proportional, Integral, and Derivative) Method as a control system for the oven. This method was chosen for its ability to automatically solve the output of a system, based on the proportionality, integrality, and derivativity of the difference between setpoint and actual output. The PID constant values were searched using the trial-and-error method, starting by setting all the constants Kp, Ki, and Kd to zero and increasing them until the system started to respond at Kp=20. After making repeated corrections, the static error (offset) can be resolved at Ki=0.4 and excessive oscillations can be mitigated at Kd=50. Based on the results of testing the oven's performance at temperatures of 50°C, 60°C, and 70°C, it was found that the overshoot was 80%, 60%, and 15%, respectively. Thus, the biggest overshoot is at the 50°C setpoint, and the smallest is at the 70°C setpoint. Based on three tests at different set points, the set point can track the actual output (settling time) in 2000 seconds

Video Recording Based Vehicle Number Plate and Speed Detection System Using YOLOv5-DeepSORT and HyperLPR

Agus Heri Setya Budi — 2024-03-05

One of the causes of accidents is the lack of vigilance among drivers and violations of vehicle speed exceeding the maximum limit. To mitigate these violations, traffic supervision is necessary, especially in accident-prone areas. This research introduces a video-based vehicle speed and license plate detection system developed using YOLOv5-DeepSORT and HyperLPR to address this issue. The system employs YOLOv5 and DeepSORT to detect and track vehicle movements, thereby obtaining the displacement of the vehicle, which serves as a reference for speed detection. HyperLPR, on the other hand, is utilized for license plate recognition. The research adopts an experimental methodology, involving video recording on the Cipali toll road section, which serves as input for the vehicle speed and license plate detection program. The evaluation of vehicle object detection using YOLOv5 yields a precision metric score of 100%. Moreover, the testing of vehicle speed detection reveals an average error percentage of 7.6% compared to the actual values. In terms of license plate detection, an overall character accuracy rate of 91.82% is achieved.Based on these findings, it can be concluded that the developed vehicle speed and license plate detection system exhibit excellent accuracy and could be considered for implementation, taking into account predefined implementation criteria.
