Abstract

The writing of this paper focuses on describing and relating simple modeling and analysis to the simulation of High-PassFilter (HPF) and Lowpass filter (LPF) designs using Op-Amp, which previously used an analog system and then converted into a digital system using input and output digital gain processing frequency which aims to strengthen the sinusoidal signal contained in the HPF and LPF systems. Filter is defined as an electrical network that is designed to pass alternating current that is increased at a predetermined frequency and blocks all alternating current that is increased at a predetermined frequency. Frequency also has types, namely analog, digital, active and passive. Analog filters are used for analog signals, digital are used for signals using digital techniques, passive filters such as resistors, capacitors, inductors, and active such as transistors or op-amps. In general, the understanding of HPF is that it passes high frequencies at the cut-off frequency and dampens low frequencies. Furthermore, LPF also has different characteristics, namely, passing low frequencies and dampening high frequencies. Currently related to digital signal processing, it can be said to be a method of manipulating, analyzing and interpreting signals, which is used to process the removal of noise or interference on several unwanted components of the signal. By knowing these characteristics, what the author did was carry out a simulation aimed at helping to obtain optimal frequency output.

Abstract

Robot Security is a robot that is responsible for security as well as patrolling. When patrol automatically, the robot requires a navigation system. The robot also needs a mapping system that is used to make a map of the environment and as information on its location according to the map. The sensors used are wheel odometry and LiDAR. The wheel odometry system often slips which causes errors in reading the actual position of the robot. To fix this problem, a sensor fusion between the Inertial Measurement Unit (IMU) and wheel odometry is used. To combine these sensors, namely using the Extend Kalman Filter (EKF) which runs on the Robot Operating System (ROS) operating system. Mapping and navigation system testing, carried out using IMU sensors and without IMU, towards the 5 target points that have been made. In the test without IMU, the error of the robot reaching the target was (x = 45.86%, y = 54.595%, and = 56.63%). After adding the IMU sensor, the robot error has decreased to (x = 2.02%, y = 1.796%, and = 0.22%). In conclusion, the data combined from the IMU sensor and wheel odometry could minimize the existing slip errors.

Abstract

Cicadas are insects that can be cultivated in Indonesia. The most common species of cicadas cultivated in Indonesia are Gryllus bimaculatus and Acheta domesticus. Cicadas are commonly used as livestock feed, including ornamental chickens, poultry, and birds, because of their high protein content. Cicadas cultivation in Indonesia is still mostly done manually, both in the process of controlling the environmental conditions around the cage and in the process of breeding cicadas eggs. One of the problems that often occurs is the temperature and humidity in the cicadas cage are not stable. Therefore, this research aims to design a system that can control the temperature and humidity in the cicadas cage. This system applies the fuzzy logic method to control actuators that can regulate the duration of spraying and the level of lighting needed in the cicadas cage based on the fuzzy rules that have been made. The components used in this system include Arduino uno, DHT22 sensor, relay, AC light dimmer, mist maker, lamp, and fan. The results of this research show that the temperature and humidity control system in a cicadas cage using fuzzy logic method with a predetermined setpoint has been realized. The accuracy testing of the DHT22 sensor obtained an error of 1.55% and a temperature accuracy rate of 98.44% and humidity of 1.66% with an accuracy rate of 97.64%. Then, the testing of the comparison results on the system and fuzzy simulation with the matlab application obtained an accuracy percentage in the mist maker testing of 97.37% and in the lamp testing of 98.81%.

Abstract

Currently, cafés are a popular place for community activity. In addition to enjoying drinks and food, the café is also a place that is used as a place for discussions, for learning/study and a meeting point for various groups, including students. A good café is one with comfortable and safe conditions. One way to ensure the comfort of café is to monitor and control the body temperature, air quality,room temperature and humidity, the number of visitors, cleanliness and the temperature in the kitchen. This research, an IoT based monitoring and control tools was developed. The goal of this tool is to monitor and control café conditions automatically real time and touchless. The sensors used collect data and read the conditions of parameters to be evaluated. Among the evaluations performed by this tool are the number of visitors (dine-in or take-away), control of temperature & humidity in the café, attendance tag cards for employees and cafe security, compliance with health protocols before entering the cafe, and measurement of a person's body temperature using infrared. In addition, if there is an anomaly in the café (temperature exceedance), the manager receives a notification in real time of what is going on in the café. Cooling fans and humidifiers are activated when the air quality is abnormal, that is, when the temperature is more than 33°C and the humidity is not 45% - 65% Relative Humidity. When the temperature in the kitchen is more than 38°C, the alarm is activated

Abstract

The increasing need for energy efficiency and more accurate monitoring of energy consumption has driven the development of intelligent energy metering systems. This Final Project discusses the development of Wireless Energy Meter that integrates sensor technology and data analysis for better monitoring and prediction of energy consumption. The main objective of this research is to improve understanding of household energy consumption patterns and develop power factor improvement algorithms that can provide better use of energy efficiency in the future. At the first stage, the system is implemented using energy sensors connected to the household electrical network. The data obtained from this sensor is sent to the Thingspeak application for later monitoring. The second stage involves developing an algorithm to automatically correct the power factor that the capacitor will later embed to correct cos phi if the existing power factor is less than a predetermined set point. The results of this study show that the system that has been developed is able to provide real-time monitoring of energy consumption and improve electricity quality for better energy efficiency in the future. This can help users to be more efficient in energy use, identify potential savings, and reduce environmental impact. In addition, this system can be used by equipment in households whose purpose is to optimize the use of daily electricity loads.

Abstract

Electric motors are electromechanical machines commonly used in industry and automotive products. Interior Permanent Magnet Synchronous Motor (IPMSM) is a synchronous electric motor with a permanent magnet that is often used on electric vehicle engines. However, one of the characteristics of an electric motor with permanent magnet is the existence of torque ripples. The presence of torque ripples in electric motors can cause vibrations in the machine which affect efficiency, structural durability and operating speed. Therefore, it is necessary to make improvements or changes to the motor design to overcome this problem. This study was conducted to analyze the effect of a modification of the electric motor parameter on the torque value in the existing design. Modifications are applied to the existing design with an initial condition of torque ripples of 42.58%. This study modified the air gap, magnet angles, magnet thickness, and opening slot width. Modifications are carried out through a finite element method-based software simulation with the Taguchi method to reduce experimental configurations of design factors from 625 to 25 experiments. Through this research on parameter modification, the results of the analysis show that each modification of the design factor has an influence on the value of torque ripples. From the process of Analysis of Mean (ANOM), it can be seen that wider air gap and slot opening, the smaller torque ripples. Then, the greater magnet rib and thicker magnet cause the greater torque ripples.

Abstract

The transition to Industry 4.0 requires major investments in devices and mechanisms that enable interconnectivity between people, machines, and processes. One important concept related to Industry 4.0 is the so-called Industrial Internet Of Things or IIoT. The application of IIoT in the industrial scope is the measurement of Overall Equipment Effectivness (OEE) through the IoT paradigma. Generally, OEE measurements are carried out manually by production operators on the machine being measured, and data processing is carried out by supervision manually as well to then analyze the OEE value of the machine being measured. In this research, an ESP32-based OEE Analysis Development Board with MQTT protocol is proposed to replace the manual OEE measurement process. The results of direct implementation on the production floor show that the ESP32-based OEE Analysis Development Board with MQTT protocol can be used as an alternative to OEE measurement with a maximum error value on OEE measurement of 16%.
