Abstract

Tugas akhir ini dirancang untuk alat pengaman gudang dengan menggunakan komunikasi LoRa gateway. Tujuan dari perancangan ini yaitu untuk meningkatkan keamanan pada gudang upaya meminimalisir tindakan pencurian serta dampak dari pencurian. Dalam perancangan tugas akhir ini terdapat dua bagian sangat penting sebagai jalur komunikasi utama yaitu node sensor dan gateway. Pada bagian node sensor terdapat beberapa komponen yang terdiri dari Sensor Magnet, Arduino Uno, Buzzer dan LoRa. Sensor magnet bertugas untuk mendeteksi keadaan pintu terbuka atau tertutup. Arduino bertugas sebagai otak untuk menjalankan kode program. Buzzer berfungsi sebagai alarm peringatan saat pintu gudang terbuka. Pentransmisian data antara node dengan gateway menggunakan komunikasi LoRa. Pada bagian gateway terdapat LoRa dan Esp32, Esp32 bertugas untuk mengolah data yang diterima serta menjembatani transmisi LoRa untuk terhubung dengan server blynk dengan menggunakan jaringan internet. Setelah itu data dari node sensor ditampilkan pada aplikasi blynk dan menerima laporan keadaan gudang dari jarak jauh serta buzzer pada gudang akan berbunyi. Pada aplikasi blynk bisa memberi perintah menghidupkan dan mematikan sistem alat dan alarm dari jarak jauh. Berdasarkan hasil pengujian yang telah dilakukan, setiap komponen dapat berfungsi dengan. Pengujian pada kondisi Los dan NLoS, transceiver dapat berkomunikasi melalui LoRa dan sampai ke aplikasi blynk dengan tepat sesuai dengan rancangan awal alat. Untuk pengujian LoRa dengan kondisi LoS memiliki batas kemampuan pengiriman pada jarak dibawah 600 m dan NLoS dibawah jarak 200 m.

Abstract

Pembangkit Listrik Tenaga Surya (PLTS) adalah salah satu pembangkit Listrik dari sumber energi terbarukan yang memiliki potensi besar dikembangkan di Indonesia. Untuk daerah yang belum terjangkau jaringan listrik, PLTS dapat dibuat dalam konfigurasi stand alone dengan menambah baterai sebagai sumber energi cadangan Ketika panel surya tidak menghasilkan daya. Untuk meningkatkan kehandalan PLTS stand alone, diusulkan sistem kendali yang terawasi dengan memanfaatkan teknologi Internet of Things (IoT) yang disebut juga dengan Supervisory Control and Data Acquisition (SCADA). Sistem SCADA PLTS stand alone diusulkan dengan menggunakan Programable Logic Controller (PLC) sebagai pusat controller dengan display control berupa Human Machine Interface (HMI), PC server, PC client dan smartphone. Konsep ini memungkinkan PLTS dikendalikan dan dimonitor dari jarak jauh. Sistem SCADA yang diusulkan diimplementasikan pada panel surya 5 x 50 WP. Hasil eksperimen menunjukan bahwa sistem SCADA yang diusulkan telah sukses mengendalikan PLTS stand alone dari berbagai display, baik dari HMI, PC server, PC client maupun dari smartphone. Sistem SCADA yang dibuat juga telah sukses menampilkan data-data parameter PLTS yang dimonitor, sehingga PLTS dapat terawasi dengan baik.

Abstract

The ballast system is crucial for maintaining the stability of ships, especially cargo ships that generally still use manual systems. The weaknesses of manual systems include low efficiency, long operational times, and the potential for technical errors (human error) that can increase the risk of accidents. This research aims to develop an automatic ballast system using Outseal PLC as the control center. The process begins by activating the system through the start button. Objects are placed on the prototype, and the system's response to tilt angles is measured using a gyroscope sensor. When a tilt angle is detected, the system automatically fills the tank with water to restore stability. The volume of water entering the tank is measured using a flowmeter sensor. Test results show that when the tilt reaches 10 degrees or -10 degrees, the system automatically fills the tank with water. This process continues until all tanks are optimally filled with a volume of 450 ml, after which the system empties all tanks. The research results indicate that the system can effectively manage stability through water filling in the tanks, and the designed program functions according to the desired specifications

Abstract

This paper presents the design and development of an Internet of Things (IoT)-based system for monitoring the speed of DC motors. Utilizing an ESP32 microcontroller integrated with infrared sensors, the system accurately measures motor speed by detecting pulses from a five-pointed star wheel attached to the motor shaft. The Arduino framework and Blynk platform are employed for real-time data visualization and remote monitoring. The system supports multiple motors, transmitting speed data to a cloud server via WiFi, allowing users to monitor performance remotely. Debouncing techniques and a moving average filter enhance data accuracy, while a correction factor refines RPM calculations. Threshold alerts notify users of excessive speeds, enabling proactive maintenance. This scalable solution is ideal for industrial applications requiring real-time monitoring and data-driven insights

Abstract

The reliability of electric motors is very important in various industries. Damage to electric motors caused by disturbances that are not detected early results in large losses, both in terms of time and cost. This research aims to design and build an Arduino-based electric motor fault detection device equipped with a PZEM-004t sensor, buzzer as an alarm, relay to turn off the motor when there is a disturbance and LCD I2C 16x2 to display the measured value. This tool is designed to provide protection to the motor from overvoltage, undervoltage and overcurrent disturbances. Based on the results of testing and analysis, the designed tool can detect and protect the motor from interference. The buzzer functions effectively as an alarm when the voltage and current values are close to the fault occurrence value. The relay can respond well in breaking the current in the motor when a disturbance occurs. Thus, this tool has the potential to be applied as a practical solution in preventing damage to electric motors in industrial environments

Abstract

Electric motor protection in modern industry is increasingly important along with technological developments and the need to maintain operational reliability and prevent unwanted disturbances. This research develops an Arduino Mega-based three-phase induction motor protection system that uses PZEM-004T sensors to monitor current and voltage, and MAX6675 sensors to accurately measure motor temperature. The monitoring data is displayed in real-time on the ILI9341 TFT LCD screen, enabling early detection of abnormal conditions such as overheat, over current, and voltage imbalance. The system provides a quick response to protect motors from potential damage, ultimately preventing significant losses and ensuring operational continuity and energy efficiency in increasingly complex industrial environments
