Abstract

Roller tyre merupakan salah satu komponen yang sangat penting dalam produksi semen. Pada PT semen padang terdapat kerusakan berupa aus yang sangat cepat dibandingkan dengan waktu umur perawatan atau pergantian alat tersebut. Sehingga komponen membutuhkan lebih banyak perawatan dari pada jadwal yang seharusnya. Maka diperlukan kajian analisis laju keausan dan menilai penyebab laju keausan roller tyre lebih cepat dari pada umur yang seharusnya. nilai terkikis ytre dalam satu kali putaran yaitu dengan waktu minimun tyre terkikis yaitu . beberapa kemungkinan yang menyebabkan peningkatan laju aus roller tyre yaitu basahnya batu kapur, tanah liat,pasir besi, rendahnya kualitas pengelasan pada sayap dan adanya kontaminasi seperti blok kayu dan plat logam yang tercampur pada batu kapur, tanah liat,pasir besi yang mengakibatkan beban kerja tyre lebih berat

Abstract

A This study proposes an optimization-based power control strategy to enhance voltage and frequency stability in micro-hydro power plants (MHPP). The approach integrates multi-objective optimization, adaptive control, predictive algorithms, and robust mechanisms to overcome instability caused by load and water flow variations. System modeling and simulation were performed in MATLAB/Simulink, followed by experimental validation on a laboratory-scale prototype. Results show significant improvements compared to conventional PID and fixed-gain Electronic Load Controllers (ELC), reducing voltage and frequency deviations by up to 69% and 67%, respectively. Total Harmonic Distortion (THD) decreased to 3.8%, power factor improved to 0.93, and overall efficiency reached 87.2%. The method proved effective, stable, and feasible for real-time microcontroller implementation, offering a reliable solution for isolated and rural MHPP systems.
