Abstract

ABSTRAK Motor induksi tiga fasa merupakan salah satu mesin listrik yang banyak digunakan dalam sistem produksi industri sebagai penggerak berbagai peralatan. Dalam pengoperasiannya, perubahan beban kerja dapat menyebabkan perubahan arus dan rugi-rugi daya yang selanjutnya memengaruhi suhu operasi motor. Penelitian ini bertujuan untuk menganalisis hubungan antara pembebanan dan suhu operasi motor induksi tiga fasa serta menentukan kondisi operasi motor pada sistem produksi di PT Integrated Terminal Palembang. Metode penelitian yang digunakan adalah metode kuantitatif dengan melakukan pengumpulan data pembebanan dan suhu operasi motor selama proses produksi. Data yang diperoleh kemudian dianalisis menggunakan analisis korelasi Pearson dan regresi linear sederhana. Hasil penelitian menunjukkan bahwa pembebanan motor berada pada rentang 55% hingga 97%, sedangkan suhu operasi motor berada pada rentang 29,8°C hingga 43,2°C. Hasil analisis korelasi Pearson memperoleh nilai koefisien korelasi sebesar 0,995 yang menunjukkan hubungan sangat kuat dan positif antara pembebanan dengan suhu operasi motor. Analisis regresi linear menghasilkan persamaan Y = 10,026 + 0,343X, yang menunjukkan bahwa setiap peningkatan pembebanan sebesar 1% diperkirakan meningkatkan suhu operasi sebesar 0,343°C. Nilai koefisien determinasi sebesar 0,991 menunjukkan bahwa 99,1% variasi suhu operasi dapat dijelaskan oleh perubahan pembebanan motor, sedangkan 0,9% dipengaruhi oleh faktor lain. Berdasarkan hasil tersebut, peningkatan pembebanan motor memiliki hubungan yang sangat kuat dengan peningkatan suhu operasi, sehingga pemantauan pembebanan dan suhu diperlukan untuk menjaga kondisi operasi motor tetap optimal. ABSTRACT Three-phase induction motors are widely used in industrial production systems as prime movers for various equipment. During operation, changes in motor load can cause changes in current and power losses, which subsequently affect the operating temperature of the motor. This study aims to analyze the relationship between motor loading and the operating temperature of a three-phase induction motor and to determine the optimal operating conditions in the production system at PT Integrated Terminal Palembang. The research used a quantitative method by collecting motor loading and operating temperature data during the production process. The collected data were analyzed using Pearson correlation and simple linear regression analysis. The results showed that the motor loading ranged from 55% to 97%, while the operating temperature ranged from 29.8°C to 43.2°C. Pearson correlation analysis resulted in a correlation coefficient of 0.995, indicating a very strong and positive relationship between motor loading and operating temperature. Simple linear regression produced the equation Y = 10.026 + 0.343X, indicating that every 1% increase in motor loading is estimated to increase the operating temperature by approximately 0.343°C. The coefficient of determination 0.991 indicates that 99.1% of the variation in operating temperature can be explained by changes in motor loading, while the remaining 0.9% is influenced by other factors. Based on these results, increased motor loading has a very strong relationship with increased operating temperature. Therefore, monitoring motor loading and temperature is necessary to maintain optimal motor operating conditions.
