ABSTRAK

PT. Barata Indonesia Persero merupakan perusahaan yang bergerak di bidang fabrikasi dan manufaktur yang berpusat di Gresik Jawa timur. Perusahaan ini memilki 4 empat buah workshop atau divisi produksi dan 1 divisi EPC yang fokus pada kegiatan pekerjaan yang berbeda-beda. Salah satu divisinya bergerak pada produksi pengecoran baja. Pada divisi pengecoran yang terletak di workshop 1 terdapat kegiatan shake out. Ventilasi pada unit tersebut tidak dapat meminimalisir debu yang dihasilkan oleh mesin shake out sehingga mengganggu para pekerja. Berdasarkan pengukuran yang dilakukan didapatkan paparan debu pada area shake out adalah 14 mgm3 dimana berdasarkan SNI 19-0232-2005 nilai tersebut melebihi NAB yaitu sebesar 10 mgm3. Untuk mengendalikan agar paparan debu pada area shake out maka perlu dilakukan engineering control yaitu dengan merancang Duct collector tipe scrubber basah. Dalam perancangan Dust Collector perlu dirancang duct sebagai saluran debu menghitung daya blower tempat penampung debu sprinkler sebagai alat untuk menyemprotkan air agar debu mengendap pipa sebagai saluran air untuk menyuplai sprinkler perhitungan daya pompa air bak air sebagai sumber airnya dan penentuan masker jika debu sudah tidak bisa dikendalikan lagi. Dari hasil perancangan dan perhitungan didapatkan diameter duct 05 m dengan daya blower 49165 Kwatt. Dimensi tempat penampung debu p 3 m l 3 m dan t 5 m. Sprinkler untuk bahaya kebakaran ringan dengan debit 225 lmenit dan tekanan 22 kgcm2. Diameter pipa air sebesar 15 inch. Dengan daya pompa air sebesar 3753052 Kwatt. APD yang akan digunakan adalah masker.


ABSTRACT

PT. Barata Indonesia Persero is a company engaged in fabrication and manufacturing in Gresik East Java. These companies have the 4 four workshops or production division and a division of EPC which focus on activities that has different work. One of its divisions engaged in the production of steel casting. In the foundry division that located in workshop 1 there is shakes out activity. Vents on the unit can not minimize the dust that produced by the shake-out machines so disrupt the workers. Based on the available exposure measurements made in the area shake out the dust is 14 mgm3 based on SNI 19-0232-2005 which exceeds the allowable value that is 10 mgm3. To control the exposure of dust at shake out area it is needed a control engineering that is design a dust collector wet scrubber type. In designing dust collector needs to designed of dust duct calculate the power blower the dust reservoir sprinkler as a means to spray water to keep dust settles the water pipe to supply the sprinkler the calculation of power water pumps water tanks and determination of the mask if the dust cant be controlled. From the results obtained design and calculation of 0.5 m diameter duct with a power blower 4.9165 Kwatt. The dimensions of the reservoir dust p 3 m l 3 m and t 5 m. Sprinklers for fire hazard with a mild discharge 225 l min and a pressure of 2.2 kgcm2. Diameter of 1.5 inch water pipe. With the power of water pump 375.3052 Kwatt. PPE to be used is the mask.
