Abstract

Hasil dari penelitian ini menunjukkan bahwa sistem penjemuran cengkeh pintar berbasis internet of things, menggunakan mikrokontroler wemos D1 sebagai pengendali dan sebagai alat mengirimkan data ke aplikasi Blynk yang nantinya data-data tersebut dapat dimonitoring dari aplikasi, sebagai masukan (input) alat ini menggunakan sensor cahaya, sensor hujan dan limit switch. Untuk keluaran ada Driver motor memberi perintah Motor DC sebagai penggerak tempat jemuran dan sesekali diaduk guna meratakan penjemuran cengkeh. Penjemuran cengkeh akan masuk pada saat hujan ketika sensor hujan akan bernilai 0 dimana nilai tegangannya 0 Vdc sehingga memberikan perintah low yang berarti mendeteksi turunnya hujan dan jemuran akan keluar kembali ketika sensor hujan bernilai 1 dimana terdapat nilai tegangan maka sensor sudah tidak mendeteksi turunnya hujan , selain itu sensor LDR akan bernilai ADC dibawah angka 200 dan mendeteksi cahaya matahari untuk mengeluarkan jemuran dan jemuran cengkeh akan masuk ketika sensor LDR bernilai sekitar 200-225 dan mendeteksi tidak ada cahaya atau gelap pada malam hari.

Abstract

Calling crane operators in industrial areas is still frequently performed manually through voice signals, direct communication, or conventional communication devices. These methods have notable limitations, particularly in noisy work environments, across long communication distances, or in spatial conditions where direct communication is unfeasible. This study aims to design a crane operator calling system based on Arduino and the LoRa E32 communication module as an efficient, low-power, and easily deployable long-range wireless communication medium. The system consists of a transmitter unit utilizing buttons, Arduino, and LoRa E32 to send data, as well as a receiver unit that processes incoming call signals to activate indicators such as a buzzer, I2C LCD, or information display. The testing methodology was comprehensively conducted, covering local component functionality and wireless signal transmission range. The functional testing results indicated that the push button, 16x2 I2C LCD, and buzzer operated optimally with a 100% success rate. Furthermore, the wireless transmission test results demonstrated that the system achieves an effective operational range of up to 180 meters in an industrial environment with stable data delivery and zero packet loss. When the distance exceeds 180 meters, communication performance begins to suffer signal degradation. By utilizing LoRa E32, this system is expected to increase communication effectiveness, reduce the risk of miscommunication, and support occupational safety in industrial environments.
