Abstrak (Berisi Bastraknya saja, Judul dan Nama Tidak Boleh di Masukan)

Stirena merupakan salah satu produk industri kimia yang digunakan sebagai bahan baku pembuatan polystirene, Acrylonitrile Butadiene Styrene (ABS) danStyrene Butadiena Latex (SBL),Styrene Butadiena Rubber(SBR), dan Unsaturated Polyester Resin (UPR).Stirenadapat diproduksi dengan beberapa proses yaitu proses Dehidrogenasi etilbenzen dan proses Oksidasi etilbenzen. Penyediaan kebutuhan utilitas pabrik berupa sistem pengolahan dan penyediaan air, sistem penyediaan steam, cooling water, dan sistem pembangkit tenaga listrik. Kapasitas produksi pabrik stirenadirencanakan 50.000 ton/tahun dengan 330 hari kerja dalam 1 tahun. Lokasi pabrik direncanakan didirikan di daerah Cilegon, Banten. Tenaga kerja yang dibutuhkan sebanyak 135 orang dengan bentuk badan usaha Perseroan Terbatas (PT) dengan struktur organisasi line and staff. Dari analisisekonomidiperoleh: Fixed Capital Investment (FCI) =Rp710.737.275.221 Working Capital Investment (WCI) =Rp125.424.225.039 Total Capital Investment (TCI) = Rp836.161.500.260 Break Even Point (BEP) =41,41% Shut Down Point (SDP) = 27,26% Pay Out Time before taxes (POT)b = 2,5years Pay Out Time after taxes (POT)a =2,7years ReturnonInvestmentbefore taxes (ROI)b = 51,77% ReturnonInvestment after taxes (ROI)a = 41,42% Discounted cash flow (DCF) = 53,2% Berdasarkan beberapa paparan di atas, maka pendirian pabrik Stirena ini layak untuk dikaji lebih lanjut, karena merupakan pabrik yang menguntungkan dari sisi ekonomi dan mempunyai prospek yang relatif cukup baik. ABSTRACT Stirene is one of the product industry chemicals are used as the raw materials for polystirene, Acrylonitrile Butadiene Styrene (ABS) danStyreneButadiena Latex (SBL),StyreneButadiena Rubber(SBR), danUnsaturated Polyester Resin (UPR).Stirene can be produced by some of the process is Process of dehidrogenation etilbenzene and Procces oxidation etilbenzene. Provision of utility plant needs a treatment system and water supply, cooling water, ,dan Generator electrical power system. Capacity of the plant is planned to production acrylonitrile is 50.000 tons/year with 330 working days in a year. The location of plant is planned in Cilegon, Banten. Labor needed in this plant as many as 135 people with a business entityform Limited Liability Company (PT) with line and staff organizational structure. From teh economic analysis is obtained : Fixed Capital Investment (FCI) =Rp710.737.275.221 Working Capital Investment (WCI) =Rp125.424.225.039 Total Capital Investment (TCI) = Rp836.161.500.260 Break Even Point (BEP) =41,41% Shut Down Point (SDP) = 27,26% Pay Out Time before taxes (POT)b = 2,5years Pay Out Time after taxes (POT)a =2,7years ReturnonInvestmentbefore taxes (ROI)b = 51,77% ReturnonInvestment after taxes (ROI)a = 41,42% Discounted cash flow (DCF) = 53,2% By considering above the summary, it is proper establishment of stirene plant for studied further, because the plant is profitable andhas good prospects future.
