Analisis kebisingan dan getaran mekanis di dalam power house pabrik kelapa sawit PT Condong, Garut, Jawa Bara
Analysis of noise and mechanical vibration in power house oil palm plant PT Condong, Garut, West Java
Abstract
Power house is the main power station plant source that produced from generator and steam engine. The objectives of this study were to analyze the level and distribution pattern of noise and mechanical vibration, determine the maximum safety work duration, and recommend a method to overcome the noise and mechanical vibration. Measurements were performed with using grid method and mapping pattern of noise and vibration was carried out in accordance with the rules of the contour. The results of noise measurements indicated that the intensity of noise in the power house ranged between 83.36 - 97.32 dB (A) and maximum intensity of the vibration acceleration that propagate to the floor ranged from 0 to 0.3 m/s2. Based on the analysis of the measurement data, it can be concluded that the power house area was the area with high noise levels. Safety duration work in power house is 3 hours per day. Therefore, worker was suggested to wear ear protector so that could work in power house for 8 hours per day. Power house merupakan stasiun penyedia sumber listrik utama pabrik yang dihasilkan dari generator dan mesin uap. Tujuan dari penelitian ini adalah menganalisis tingkat dan pola sebaran kebisingan dan getaran mekanis, menentukan durasi aman maksimum pada area kerja, dan memberikan rekomendasi untuk mengatasi masalah kebisingan dan getaran mekanis tersebut. Pengukuran dilakukan dengan metode grid dan pemetaan pola kebisingan dan getaran dilakukan sesuai dengan kaidah kontur. Hasil pengukuran kebisingan menunjukkan intensitas kebisingan pada power house berkisar 83.36–97.32 dB(A) dan intensitas percepatan getaran maksimum yang merambat ke lantai berkisar 0 sampai 0.3 m/s[2]. Berdasarkan analisis data pengukuran, dapat disimpulkan bahwa daerah power house merupakan daerah dengan tingkat kebisingan yang tinggi. Durasi aman bekerja di dalam power house adalah 3 jam per hari. Oleh karena itu, pekerja disarankan untuk menggunakan pelindung telinga agar bisa bekerja di dalam power house selama 8 jam kerja per hari.
