Abstract

Pabrik sorbitol merupakan pabrik yang bergerak di bidang industri gula rendah kalori. Industri sorbitol dinilai sangat strategis karena banyak dimanfaatkan di berbagai industri dengan tingkat pertumbuhan konsumsi meningkat lebih dari 3% per tahun. Saat ini, Indonesia hanya memiliki 3 pabrik sorbitol, dibutuhkan peningkatan peningkatan kapasitas produksi agar tidak terjadi defisit neraca sorbitol. Dipilih tepung jagung sebagai bahan baku utama karena memiliki kandungan pati yang tinggi serta jumlahnya yang melimpah di Indonesia. Pembuatan sorbitol dari bahan baku tepung jagung melalui dua tahap proses utama, tahap pertama yaitu hidrolisa atau proses perubahan starch (pati) menjadi glukosa dengan menggunakan enzim dan tahap kedua yaitu proses pengubahan glukosa menjadi sorbitol dengan proses hidrogenasi katalitik. Proses pembuatan sorbitol dengan hidrogenasi katalitik dilakukan dengan mereaksikan larutan glukosa dan gas hidrogen bertekanan tinggi dengan menambahkan katalis Raney Nickel dalam reaktor hidrogenasi bertipe batch. Gas hidrogen masuk dari bawah reaktor secara bubbling dan larutan glukosa diumpankan dari atas reaktor sehingga terjadi reaksi. Produk yang dihasilkan adalah grade sorbitol syrup non-crystallizing dengan konsentrasi 70% atau jika pada SNI disebut sorbitol cair Tipe-015. Pabrik sorbitol ini direncanakan akan didirikan di Kabupaten Lamongan, Provinsi Jawa Timur tepatnya di Kawasan Ekonomi Khusus (KEK) Kabupaten Lamongan yang berlokasi di Kecamatan Brondong. Dengan pertimbangan ketersediaan bahan baku, lahan, nilai UMK tenaga kerja, dan letaknya yang strategis untuk pemasaran. Pabrik sorbitol direncanakan beroperasi secara kontinyu 24 jam selama 330 hari pertahun operasi dengan perencanaan kapasitas produksi sebesar 15.000 ton/tahun, jumlah tenaga kerja sebanyak 80 orang/hari, kebutuhan bahan baku tepung jagung sebesar 12.451 ton/tahun. Dari analisa perhitungan ekonomi yang dilakukan, pendirian pabrik sorbitol membutuhkan investasi sebesar Rp 555.957.931.022, dengan IRR sebesar 19,44%, POT selama 4,43 tahun, dan BEP sebesar 24,01%. Ditinjau dari segi teknis maupun ekonomis, pabrik sorbitol dari tepung jagung ini dinilai layak untuk didirikan.

Sorbitol plant is a plant engaged in the low-calorie sugar industry. The sorbitol industry is considered very strategic because it is widely used in various industries with consumption growth rates increasing by more than 3% per year. At present, Indonesia only has 3 sorbitol plants, it needs an increase in production capacity to avoid a sorbitol balance deficit. Corn starch was chosen as the main raw material because it has a high starch content and abundant amount in Indonesia. Making sorbitol from raw materials of corn starch through two main process stages, the first stage is hydrolysis or the process of changing starch (starch) into glucose using enzymes and the second stage is the process of converting glucose into sorbitol by catalytic hydrogenation process. The process of making sorbitol by catalytic hydrogenation is carried out by reacting a high pressure glucose and hydrogen gas solution by adding Raney Nickel catalyst in a batch type hydrogenation reactor. Hydrogen gas enters from the bottom of the reactor by bubbling and glucose solution is fed from the top of the reactor so that a reaction occurs. The product produced is a non-crystallizing syrup sorbitol grade with a concentration of 70% or if the SNI is called Type-015 liquid sorbitol. This sorbitol plant is planned to be established in Lamongan Regency, East Java Province, precisely in the Kawasan Ekonomi Khusus (KEK) located in Brondong District. In consideration of the availability of raw materials, land, labor market value, and its strategic location for marketing. The sorbitol plant is planned to operate continuously 24 hours for 330 days per year of operation with a planned production capacity of 15,000 tons / year, a workforce of 80 people / day, raw material requirements of corn starch 12,451 tons / year. From the analysis of economic calculations carried out, the establishment of the sorbitol plant requires an investment of Rp 555,957,931,022, with an IRR of 19.44%, POT for 4.43 years, and BEP of 24.01%. In terms of technical and economic aspects, the sorbitol plant from corn starch is considered feasible to be established.
