ABSTRAK

Dalam tugas akhir dilakukan perancangan untuk mereduksi bunyi dan getaran yang dihasilkan oleh kompresor dengan cara enclosure besar mesin dalam ruang terbuka open space kemudian ditentukan nilai transmission loss serta dicari bahan yang sesuai dengan nilai transmission loss yang ditetapkan atau lebih tinggi sedangkan bahan untuk penelitian yang dipakai load vynl dan polycarbonate. Dari hasil penelitian bahwa setelah diberi enclosure dan mendapatkan nilai transmission loss dengan memakai bahan mass loaded vynl noise barrier dan bahan polycarbonate ternyata mampu mereduksi bising sehingga menghasilkan nilai TTB sebagai berikut untuk bahan mass loaded vynl noise barrier jarak 2 m nilai TTB yaitu 698 - 729 dBA sedangkan jarak 5 m nilai TTB yaitu 666 707 dBA. Untuk polycarbonate jarak 2 m nilai TTB yaitu 703 738 dBA. sedangkan jarak 5 m nilai TTB yaitu 684 723 dBA maka hasil nilai TTB sesuai dengan standar yang ditetapkan pemerintah.


ABSTRACT

In the end the task is done for the design reduction sound and vibration generated by the compressor with the engine enclosure in a large open space then determined the value of transmission loss and the search for materials that match the value of transmission loss is determined or higher while the material for research mass loaded noise barrier vynl used to load and polycarbonate. From the results of the research that is given after the enclosure and get the value of transmission loss with the use of mass loaded noise barrier vynl and polycarbonate material was capable of so noisy reduction values as follows TTB for mass loaded noise barrier vynl distance of 2 m values TTB namely 69.8-72.9 dBA while 5 m distance value TTB is 66.6 - 70.7 dBA. For polycarbonate distance 2 m nilai TTB yaitu 703 738 dBA. 5 m distance while the value of TTB is 68.4 - 72.3 dBA then the value of TTB in accordance with the standards set by the government
