ABSTRAK

PT. X merupakan perusahaan dibidang eksploitasi migas yang salah satu proses pemurnian minyak mentah dengan pemisahan antara minyak gas dan airnya menggunakan separator PV 9900. Area separator PV 9900 ini memiliki tingkat kebisingan tinggi mencapai 99.01 dB dan pada area komunitas sekitar Central Processing Area CPA memiliki tingkat kebisingan mencapai 73.908 dBA. Pada penelitian ini pengukuran kebisingan dilakukan dengan menggunakan Sound Level Meter. Setelah diperoleh data kebisingan dilakukan pembuatan peta kebisingan menggunakan program Surfer 8 untuk mengetahui pola penyebaran kebisingan pada daerah tertentu. Selanjutnya perhitungan kebisingan overall separator PV 9900 pipa saluran gas dan area komunitas CPA untuk mengetahui Noise Reduction NR tertinggi yang akan dijadikan patokan dalam perhitungan. Pengendalian kebisingan dilakukan dengan desain enclosure separator PV 9900 wrapping pipa saluran gas dan barrier alam. Desain menggunakan material akustik baja 30 mm dan plester akustik 9 mm yang disatukan dengan laminasi. Wrapping pipa saluran gas digunakan rockwool 25 mm dan pelindung akustik KNM-100AL 3 m. Barrier alam dengan penanaman pohon glodokan tiang Polyalthia longifolia yang ditanam di area buffer zone terluar dan area paling luar CPA. Desain enclosure separator PV 9900 tersebut mampu mereduksi kebisingan sebesar 25.686 dB. Wrapping pipa saluran gas mampu mereduksi kebisingan pipa saluran gas sebesar 64.4 dB. Sedangkan untuk barrier alam dengan penanaman pohon polyalthia longifolia bisa mereduksi hingga di bawah 55 dBA.


ABSTRACT

PT X is an oil and gas exploitation company that refining crude oil by using PV 9900 separator. As the reality the PV 9900 separator has noise level up to 9901 dB in this separator and up to 73 dB surrounding Central processing Area CPA. In this research the noise level is measured from the data of the measurement it is created into noise mapping using Surfer 8 to pattern noise distribution in some area. The measurement of overall separator PV 9900 gas pipe line and CPA are used to find out the noise reduction which is used to become the calculation standard. The noise control is enclosure in PV 9900 separator wrapping pipeline and natural barrier surrounding the CPA. The design which is used 30 mm steel and 9 mm acoustical plaster which is combined with lamination. The gas pipelines wrapping is used 25 mm rockwool and 3 mm acoustical protective KNM-100AL. The natural barrier is used glodokan tiang trees Polyalthia longifolia which planting in the buffer zone and outside the CPA Central Processing Area. The enclosure design of separator PV9900 design can reduce noise until 65.6 dBA. In other side gas pipelines wrapping can reduce pipe noise until 64.4 dBA. The natural barrier that planting Polyalthia longifolia it can reduce under 55 dBA.
