Abstract

Manual data recording for battery preventive maintenance (PM) is prone to error and inefficient. This study developed an integrated automated data acquisition system to address these issues. The implemented system utilizes an Arduino Nano with a voltage sensor and Bluetooth module for measurement and wireless transmission. A custom LabVIEW interface receives the data in real-time and provides visualization, while a MySQL database serves as a centralized repository. Testing demonstrated the sensor circuit's high reliability, showing an average measurement error of 0.50% and a Mean Absolute Error (MAE) of 0.01 V. Most significantly, the system reduced the total PM execution time by 24% by eliminating manual transcription and double-entry. This integrated solution presents a practical and cost-effective framework for modernizing PM operations in industrial settings, enhancing both data accuracy and operational efficiency.

Abstract

Kemajuan industri meningkatkan kebutuhan pemantauan kinerja mesin berputar secara akurat, salah satunya melalui penggunaan tachometer. Alat ini tersedia dalam mode pengukuran kontak, non-kontak, dan linier sehingga memerlukan kalibrasi berkala untuk menjaga akurasi. Namun, sebagian besar perangkat kalibrator tachometer yang tersedia saat ini hanya mendukung salah satu metode pengukuran, memiliki kompleksitas rangkaian tinggi, atau merupakan produk impor dengan Tingkat Komponen Dalam Negeri (TKDN) yang rendah. Oleh karena itu, dikembangkan alat kalibrator dua mode, yaitu kontak dan non-kontak, bernama LoKal-RPM (Loro Kalibrator RPM). Sistem ini menggunakan motor DC untuk mensimulasikan kecepatan putar pada mode kontak dan sumber cahaya periodik berbasis LED dengan kendali frekuensi pada mode non-kontak. Hasil pengujian menunjukkan bahwa pada mode kontak, motor DC menghasilkan putaran stabil baik tanpa beban maupun dengan beban, dengan error maksimum 0,11% pada rentang 500–5.000 rpm terhadap tachometer referensi. Pada mode non-kontak, sistem LED menunjukkan error maksimum 0,10% pada rentang 300–6.000 rpm terhadap tachometer referensi.
