Abstract

This paper presents a performance comparison of the circular patch unit cell as a unit cell for reflector application at 3.5 GHz frequency using a dielectric substrate between FR4 and F4BMX220 substrates. A circular patch is chosen as the unit cell of a reflector because it is commonly used, fabricated, and has a wider bandwidth compared to other structures. A performance comparison of the circular patch on both dielectric substrates is presented in a graph of S-parameters, reflection phase, and operating bandwidth, as well as in the table of dimensions, where the result is performed by simulation using CST software. Based on the simulated results, the F4BMX220 has a better performance compared to the FR4 in terms of the reflection value, operating bandwidth, and dielectric substrate thickness. However, a circular patch diameter when using the F4BMX220 is bigger than when using the FR4 substrate because the FR4 substrate has a higher dielectric constant than the F4BMX220, which is twice the F4BMX220 dielectric constant. Also, the F4BMX220 substrate has a narrower bandwidth compared to the FR4 substrate, which is a difference of around 0.1 GHz. The circular patch when using the F4BMX220 substrate has 0.96 of a reflection value, 0.007 of an absorption value, -6.77° of the reflection phase, and 0.24 GHz of the operating bandwidth at the normal incident wave angle (0°). Also, it can be properly worked if the incident wave angle is moving until 60°. The F4BMX220 substrate has the best performance compared to the FR4 substrate because the reflection value is much better value, even at the incident wave angle of 60°.

Abstract

Belum adanya sistem layanan administrasi desa di Desa Dukuh, Boyolali secara online menyebabkan pelayanan yang diberikan kurang optimal. Pelayanan yang selama ini diberikan oleh perangkat desa Dukuh masih bersifat manual. Ketika warga membutuhkan surat, warga menghubungi Kepala Dusun melalui telepon atau via whatsapp atau datang kerumah Kepala Dusun untuk minta dibuatkan surat. Proses ini tentu kurang efektif, mengingat warga Desa Dukuh mayoritas bekerja sebagai karyawan swasta/pabrik dan petani. Jika sewaktu-waktu warga membutuhkan surat yang sifatnya mendesak, akan memakan waktu untuk mendapatkan surat. Untuk mengatasi masalah tersebut, maka dibangun “Sistem Layanan Administrasi Desa di Desa Dukuh, Boyolali Berbasis Web dan Android”. Dengan pendampingan implementasi sistem layanan administrasi desa berbasis web dan android kepada perangkat desa dan warga desa Dukuh akan membantu warga untuk mendapatkan surat secara mudah dan membantu perangkat desa untuk memproses surat dengan cepat. Dengan menggunakan sistem ini, warga bisa secara mandiri mengakses aplikasi sesuai dengan kebutuhan tanpa harus menemui Kepala Dusun atau datang kerumah Kepala Dusun untuk minta dibuatkan surat.

Abstract

Proportional Integral Derivative (PID) is a control system that combines proportional, integral, and derivative elements. PID control is often used in industrial machines. One of these machines is a 3-phase motor. Another important component in the industrial world is the Programmable Logic Controller (PLC) which is usually paired with an interface tool, namely HMI. The importance of a deep understanding of PID, PLC, HMI, and 3-phase motors is very important for students to be better prepared to face the real world of work. The application of the PID controller module using PLC as a learning tool at the Semarang State Polytechnic is still lacking, one of the reasons being the availability of PID controller modules that are inadequate. This study aims to design a PID controller module using PLC on a 3-phase motor. The creation of this practical module uses Omron HMI as a monitor in controlling 3-phase motor movements. Push buttons and switches are used as input components. Omron CP1E PLC is used as a processing component according to motor movement. The encoder is used to read the motor speed with an output in the form of a square signal which will be the feedback input read by the PLC. The inverter is used as a 3-phase induction motor driver. Buzzer and lights are used as indicators in controlling 3-phase motors. 3-phase induction motors are the main output components in this PID system. The power supply is used as a voltage source for the PLC so that the power supply must always be connected to a 220 VAC source. MCB is used as a protection system on the module.

Abstract

This paper presents the implementation of an AIoT-based Human Activity Recognition (HAR) framework designed for multipurpose applications. The framework integrates sensor data from wearable IoT devices, which is then processed by AI algorithms to classify and predict human activities in real-time. It utilizes machine learning models, particularly machine learning techniques, to analyze complex activity. Our framework uses all open-source IDEs, which is able to replicate and modify. For this paper we give examples of how to use our framework as gamification of a workout practice. The Idea is to recognize user activity including (bicep curl, shoulder press, and front rise) using accelerometer data, and then send recognized activity to our developed online game (pop-balloon). M5StickC Plus used as the hardware which already equipped with IMU sensor and power management. Furthermore, it has small form factor fit for wearable application. Before real-time performance was taken, we evaluated 5 different machine learning model and choose which one is more optimized. The five models include Naïve Bayes, Support Vector Machine (SVM), AdaBoost, ZeroR, and Random Forest. Accuracy given for offline analysis were 97.68%, 98.97%, 41.62%, 25%, 100% respectively to the previous model. In the final, for real-time performance we choose SVM model which most optimized even though the accuracy reduced to 89.67% for this task.

Abstract

Bottle filling, closing, and labellingmachine control and monitoring tool using Programmable Logic Controller (PLC) and Human-Machine Interface (HMI). This tool is designed to optimize the production process in the bottled beverage industry,with dimensions of 200 cm × 70 cm × 100 cm. The conveyor transports bottles through the filling, capping, and labeling units. In each unit, sensors are installed to detect the presence of bottles. Bottle liquid volume is determined through time settings inputted through the HMI,and the filling is performed by a water pump. After filling, bottles are capped and tightened mechanically using an air impact system. Labeling is handled by two DC motors which unroll the label and rotate the bottle, ensuringthe label adheres evenlyto all sides of the bottle. The number of bottles produced is calculated using a capacitive proximity sensor and displayed on the HMI. Testing results show that the system effectivelycontrols and monitors the bottle filling, capping, and labeling process viaPLC and HMI. Based on the test results on the bottle filling unit, the system can fill water into the bottle with a maximum percentage error of 0.5% on a 1000 ml volume bottle. In the capping unit, the success rate achieved is 70%, while the success rate in the bottle labeling unit is 80%.
