Abstract

Sirup glukosa banyak digunakan oleh industri-industri makanan dan minuman ringan karena memiliki beberapa kelebihan dibandingkan gula tebu (sukrosa). Tingginya kebutuhan sirup glukosa yang masih didatangkan dari luar negeri merupakan latar belakang pendirian pabrik sirup glukosa. Salah satu sumber pati yang dapat digunakan untuk membuat sirup glukosa adalah buah mangrove. Mengingat tingginya produksi buah mangrove dan tidak banyak penggunaan buahnya mengakibatkan buah mangrove tidak memiliki harga jual. Proses pembuatan sirup glukosa dibagi menjadi 3 tahapan proses, yaitu pre-treatment, hidrolisis, dan pemurnian. Tahap pretreatment bertujuan untuk mempersiapkan bahan baku buah mangrove jenis (Bruguiera Gymnorrhizae) menjadi bentuk bubur yang dapat memudahkan proses pemecahan pati menjadi dekstrin. Tahap hidrolisis merupakan proses konversi pati menjadi glukosa. Proses pemurnian dilakukan untuk mendapatkan sirup glukosa yang bersih dan jernih. Pabrik direncakan mulai beroperasi pada tahun 2020. Berdasarkan data yang diperoleh, dari data ekspor impor yang terus meningkat didapat etimasi kapasitas pabrik yang dibutuhkan sebesar 190836.325 ton/tahun. Namun dikarenakan produksi buah mangrove hanya mencapai 115 ton/ hektar setiap tahunnya, maka ditetapkan kapasitas produksi pabrik sirup glukosa sebesar 4180,64 ton/tahun. Lokasi pendirian pabrik direncanakan di Gresik, Jawa Timur. Pabrik sirup glukosa merupakan perusahaan yang berbadan hukum Perseroan Terbatas dengan sistem organisasi garis dan staff. Untuk dapat mendirikan pabrik sirup glukosa dengan proses enzimatis berkapasitas 4180,64 ton/tahun diperlukan total modal investasi sebesar Rp268.275.781.239,21. Total biaya produksi Rp62.684.945.213,07, dengan estimasi penjualan per tahun Rp66.890.189.767,62. Estimasi umur pabrik 10 tahun dan waktu pengembalian pinjaman selama 10 tahun. Dapat diketahui IRR sebesar 13,7%, POT selama 6,3 tahun, BEP sebesar 64%.
====================================================================================================================================
Glucose syrup is widely used by food and soft drink industries because it has several advantages over sugar cane (sucrose). The high need for glucose syrup that is still imported from abroad is the background for the establishment of a glucose syrup factory. One source of starch that can be used to make glucose syrup is mangrove fruit. Given the high production of mangrove fruit and not much use of the fruit, the mangrove fruit has no selling price. The process of making glucose syrup is divided into 3 stages of the process, namely pre-treatment, hydrolysis, and purification. The pretreatment stage aims to prepare the raw material for the type of mangrove fruit (Bruguiera Gymnorrhizae) into a form of porridge which can facilitate the process of breaking starch into dextrin. The hydrolysis stage is the process of converting starch into glucose. The purification process is done to get clean and clear glucose syrup. The plant is planned to start operating in 2020. Based on the data obtained, from the data of increasing export and import data, it is estimated that the required plant capacity is estimated to be 190836,325 tons/year. However, because mangrove fruit production only reaches 115 tons/hectare per year, the glucose syrup factory production capacity is set at 4180.64 tons/year. The location of the factory establishment is planned in Gresik, East Java. The glucose syrup factory is a company incorporated as a Limited Liability Company with a line organization system and staff. To be able to establish a glucose syrup factory with an enzymatic process with a capacity of 4180.64 tons/year, a total investment capital of Rp268,275,781,239.21 is required. The total production cost is Rp.62,684,945,213.07, with estimated sales per year of Rp.66,890,189,767.62. The estimated age of the plant is 10 years and the loan repayment period is 10 years. It is known that the IRR is 13.7%, POT is for 6.3 years, BEP is 64%.
