Abstract

Sistem SCADA (Supervisory Control and Data Acquisition) merupakan teknologi komputer yang banyak digunakan pada sistem kendali di dunia industri saat ini. Pada penelitian ini sistem SCADA digunakan pada plant motor penggerak konveyor karena plant tersebut sangat banyak digunakan di industri, hampir semua jenis industri menggunakan konveyor untuk memindahkan barang dari satu tempat ketempat lainnya. Implementasi kontrol yang digunakan pada penelitian ini adalah metode kontrol PID (Proportional Integral Derivative) yang akan mengoreksi error kecepatan dengan menggunakan rotary encoder sehingga kecepatan putaran motor DC sesuai dengan nilai setpoint yang ditentukan melalui sistem SCADA. Kontroler utama pada sistem ini adalah PLC (Programmable Logic Controller) Siemens S7-1200 yang berperan sebagai RTU (Remote Terminal Unit) pada sistemSCADA. Nilai parameter PID yang ditentukan pada sistem SCADA adalah Kp = 0,25, Ti = 0,8 dan Td= 0,08. Berdasarkan hasil pengujian, sistem SCADA bisa mengendalikan plant dengan baik dengan nilai error steady state sebesar 1,1% - 3,4% baik saat conveyor belt bekerja dengan beban maupun tanpa beban. Dengan sistem SCADA, monitoring sistem bisa dilakukan dari jarak jauh tanpa harus datang langsung ke lokasi tempat plant berada sehingga lebih memudahkan proses monitoring dan kontrol plant di dunia industri. ABSTRACT The SCADA (Supervisory Control and Data Acquisition) system is a computer technology that is widely used in control systems in today's industrial world. In this study, the SCADA system was used in a motor conveyor driving because the plant is very widely used in industry, almost all types of industry use conveyors to move goods from one place to another. The control implementation used in this study is the PID (Proportional Integral Derivative) control method which will correct errors of the speed sensor input variable using a rotary encoder so that the DC motor rotation speed match the setpoint value determined through the SCADA system. The main controller in this system is the Siemens S7-1200 PLC (Programmable Logic Controller) which acts as the RTU (Remote Terminal Unit) on the SCADA system. The PID parameter values determined in the SCADA system are Kp = 0.25, Ti = 0.8 and Td = 0.08. Based on the test results, the SCADA system can control the plant well with a steady state error value of 1.1% - 3.4% both when the conveyor belt is working with or without load. With the SCADA system, monitoring the system can be done remotely without having to come directly to the location where the plant is located, making it easier for the process of monitoring and controlling plants in the industrial world.

Abstract

Irrigation involves the artificial application of water to the soil, crucial to promoting crop growth where rainfall is insufficient, thus supporting healthy plant development and increasing yields. In Indonesia, a large part of the irrigation infrastructure is in disrepair, affecting agricultural productivity and causing food shortages and economic instability, especially among low-income populations. To manage this, local organizations oversee the maintenance of irrigation systems categorized into primary, secondary, and tertiary canals, prioritizing repairs based on severity. Meanwhile, mobile phones have become an essential part of everyday life in Indonesia due to their affordability and utility, which facilitate access to digital resources. Anticipated to reach 97% smartphone penetration by 2029, particularly with Android devices, this technology supports an innovative mobile application strategy for irrigation maintenance. This app enables farmers and community members to report issues collaboratively, accelerating the identification and repair process to improve agricultural management. Complementing this approach, OpenStreetMap (OSM) provides an editable global map resource, continuously updated by users and leveraging tools such as Leaflet JS to offer developers the ability to create interactive and customizable maps, enhancing infrastructure management through community participation. This study introduces a mobile reporting system for managing irrigation infrastructure, integrating several technical components to effectively address maintenance needs. Requiring compatible browsers like Chrome and Safari with specific minimum versions and at least Android 4.0 for accessibility, the system features a public-facing mobile website using OpenStreetMap for mapping. It includes a back-end server that serves mobile and monitoring applications and uses Firebase to store images of irrigation damage while managing database operations with PostgreSQL. The technical setup involves Windows 11, Visual Studio Code, PHP with Laravel for backend operations, and React JS with Leaflet JS for front-end design, running on hardware featuring an Intel Core i5 CPU and NVIDIA GTX 1650 GPU. Key APIs like Get Close Segments, Post Report, and Get The system facilitates data submission with locations and photos, provides report history viewing and filtering, and enhances user engagement through transparency in infrastructure management. The test with local farmers demonstrated the responsiveness and compatibility of the system across various platforms, ensuring that user reports are processed efficiently with reliable admin access for monitoring and tracking.

Abstract

Changes in irradiation conditions cause photovoltaic (PV) power to be fluctuating, so the operating point of the PV is not always at the maximum power point. On the other hand, the battery charging process needs to be controlled so that it can be stopped when the battery reaches a full condition. This condition indicates the need for a control system that not only tracks the maximum PV power but also adjusts the charging process based on the battery's condition. This research develops a PV-based battery charging system using a buck converter that integrates Perturb and Observe (P&O) Maximum Power Point Tracking (MPPT), Proportional-Integral (PI) controller, and Coulomb Counting-based State of Charge (SOC) estimation. The P&O algorithm is used to determine the PV voltage reference, then the PI Controller adjusts the duty cycle of the buck converter so that the operating point follows this reference. Meanwhile, Coulomb Counting is used to monitor SOC and control the cut-off and restart charging mechanisms. The simulation results show that the system is capable of adjusting the PV operating point to changes in source conditions and maintaining the charging process under normal conditions. The battery SOC reaches 100% at around 3.45 s, followed by a decrease in duty cycle from about 0.5 to 0 and charging current to 0 A. These results show that the integration of MPPT, buck converter, and SOC-based supervision is capable of controlling the charging process according to PV operating conditions and the battery's SOC limits.
