Abstract

Pendahuluan: Bayi dengan berat badan lahir rendah (BBLR) yang menjalani perawatan di NICU seringkali menimbulkan tekanan psikologis pada orang tua. Kondisi tersebut dapat memicu stres yang berpengaruh terhadap kemampuan mereka dalam menggunakan mekanisme koping. Tujuan: Penelitian ini bertujuan untuk menganalisis hubungan antara tingkat stres dengan mekanisme koping pada orang tua bayi BBLR di ruang NICU RSUD Suradadi. Metode: Penelitian ini menggunakan pendekatan kuantitatif dengan desain cross-sectional. Sampel berjumlah 43 responden yang dipilih menggunakan teknik purposive sampling. Pengukuran tingkat stres menggunakan instrumen DASS 42, sedangkan mekanisme koping diukur menggunakan COPE Scale. Analisis data dilakukan menggunakan uji Kendall’s tau. Hasil: sebagian besar responden mengalami stres berat (44,2%) dan lebih banyak menggunakan mekanisme koping maladaptif (58,1%). Uji statistik menunjukkan nilai τ = 0,293 dengan p = 0,046 (p < 0,05), yang mengindikasikan adanya hubungan yang signifikan dengan kekuatan korelasi lemah antara kedua variabel. Kesimpulan: Terdapat hubungan yang signifikan antara tingkat stres dengan mekanisme koping pada orang tua bayi BBLR di NICU. Oleh karena itu, diperlukan upaya intervensi untuk meningkatkan kemampuan koping yang adaptif.

Abstract

Three-phase induction motors are key components in industrial power systems, but their performance is susceptible to internal disturbances such as stator resistance imbalance caused by aging, overheating, or manufacturing defects. This study aims to systematically analyze the impact of stator resistance imbalance on the efficiency and torque characteristics of squirrel cage rotor induction motors using equivalent circuit-based mathematical modeling. Unlike previous studies that used external resistors, this study modifies the stator resistance parameters directly in the model to represent more realistic internal degradation. Simulations were performed on a 3.73 kW, 400 V, 50 Hz motor with resistance imbalance variations from 0% to 20%. The results show that the imbalance causes uneven current distribution and an increase in stator copper losses of up to 5.94% at 20% conditions, although the percentage of current imbalance remains below 1%. As a result, the efficiency decreases linearly from 92.97% to 92.62%, while the mechanical torque experiences a small decrease from 95.88 Nm to 95.28 Nm. This phenomenon also has the potential to increase torque ripple and uneven heating. This study demonstrates that stator resistance imbalance, even small ones, has a significant impact on motor performance and lifespan, and therefore needs to be considered in predictive maintenance strategies and energy efficiency optimization.
