Abstract

ABSTRAK PT.X merupakan salah satu contoh perusahaan yang bergerak di bidang industri fabrikasi, dimana dalam melakukan kegiatan produksinya menghasilkan partikel-partikel debu yang dapat mencemari lingkungan kerja sekitar dan mengganggu kesehatan pekerja. PT.X adalah perusahaan pengecoran yang dibagi menjadi beberapa tahap mulai dari tahap pettern shop, sand moulding, melting dan finishing. Pada area sand moulding di PT.X sangat besar kandungan partikel-partikel debu yang dihasilkan karena diarea tersebut salah satu bahan produksinya yaitu menggunakan pasir silika Dari data yang didapat pada tanggal 4 november 2014 dari hasil pengukuran kualitas udara di PT.X yaitu sebesar 18,28 mg/m³. Pengukuran tersebut dilakukan di area sand moulding atau bengkel pengecoran pada PT.X. Untuk menghindari bahaya gangguan atau kesehatan pekerja akibat paparan debu. Penelitian ini bertujuan untuk mengendalikan debu yang dihasilkan dari area sand moulding dengan melakukan perancangan dust collector system pada area sand moulding. Pada perancangan ini meliputi perancangan hood sebagai media penghisap debu, perencanaan duct sebagai media penyalur kontaminan yang telah dihisap oleh hood menuju ke bagfilter, perancangan bag filter sebagai filter debu silica, kemudian setelah di filter keluaran berupa udara bersih dan perhitungan daya motor penggerak blower, sebagai motor/daya penggerak. Area sand moulding memiliki panjang sebesar 7 meter, lebar 7 meter dan tinggi 10 meter dengan hood tipe canopy sebanyak 4 buah dan memiliki kecepatan udara sebesar 200 fpm atau 1,01 m/s. diameter yang direncanakan untuk duct cabang sebesar 0,28 meter dan duct utama sebesar 0,66 meter. Daya motor penggerak blower sentrifugal sebesar 11,22 hp. Ketebalan pipa diameter 660 meter = 18 SWG = 1,219 mm , diameter 1360 meter = 17 SWG = 1422 mm dan jenis material adalah tipe galvanize iron. Diameter bag 6 in = 0,15 meter , tinggi filter = 6 meter , jumlah bag = 140 buah dengan panjang = 14 bag , lebar = 10 bag , panjang bagfilter = 4 meter, lebar bagfilter = 2,4 meter, jarak pusat ke pusat bag pada panjang 260 meter, lebar = 220 meter. Sudut hooper 70 0 , tinggi hooper 2,5 meter. Kata kunci: Blower, Bagfilter, Duct , Galvanize iron, Hood, Hooper ABSTRACT PT.X is one example of a company that is engaged in the fabrication industry, which in its production activities produce dust particles that can contaminate the surrounding work environment and harm the health of workers. PT.X foundry is a company which is divided into several stages starting from pettern shop, sand molding, melting and finishing. In the area of molding sand in PT.X very large content of dust particles generated due to the diarea one production materials that use silica sand From the data obtained on 4 November 2014 from the results of measurements of air quality in PT.X that is equal to 18, 28 mg / m³. The measurement is carried out in an area of sand molding or casting workshop at PT.X. To avoid the danger of interference or health of workers due to exposure to dust. This research aims to control dust generated from molding sand area by designing dust collector system on molding sand area. At this design includes the design of the vacuum cleaner hood as media, media planning channeling duct as a contaminant which has been sucked by the hood toward bagfilter, the design of the dust filter bag filter as silica, then once in the output of clean air filter and blower motor power calculations, as the motor / drive power. Area molding sand has a length of 7 meters, a width of 7 meters and a height of 10 meters with a hood-type canopy of 4 pieces and have air speed of 200 fpm or 1,01 m / s. planned for duct diameter of 0.28 meters and a branch of the main duct by 0.66 meters. Centrifugal blower motor power of 11.22 hp. The thickness of the pipe diameter of 660 meters = 18 SWG = 1.219 mm, diameter = 17 SWG 1360 meters = 1422 mm and material type is the type of galvanized iron. Diameter bag 6 in = 0.15 meter, filter = 6 meters high, the number of bag = 140 pieces with a bag length = 14, width = 10 bag, bagfilter = 4 meters long, 2.4 meters wide = bagfilter, center to center distance bag on the length of 260 meters, width = 220 meters. Angle 700 hooper, hooper 2.5 meters high. Keywords: Blower, Bagfilter, Duct, Galvanize iron, Hood, Hooper
