Abstract
Sorbitol adalah senyawa monosakarida polyhydric alcohol. Senyawa ini merupakan suatu gula alkohol yang dimetabolisme lambat di dalam tubuh. Sorbitol diperoleh dengan cara mengubah gugus aldehid menjadi gugus hidroksil. Industri sorbitol dinilai sangat strategis karena sorbitol banyak dimanfaatkan di berbagai industri, seperti industri pangan, farmasi, kosmetik, kimia serta bidang industri lainnya. Sehingga, bahan baku sorbitol secara tidak langsung sudah menjadi bagian dari kebutuhan sehari-hari. Sorbitol dapat dibuat dengan beberapa cara dari berbagai jenis bahan baku, dengan kondisi operasi serta konversi yang berbeda. Pembuatan sorbitol dari bahan baku tepung tapioka melalui dua tahap proses utama, tahap pertama yaitu proses perubahan starch (pati) menjadi glukosa dengan menggunakan enzim dan tahap kedua yaitu proses pengubahan glukosa menjadi sorbitol dengan proses hidrogenasi katalitik. Pabrik sorbitol ini direncanakan akan didirikan di Kabupaten Pati, Provinsi Jawa Tengah. Dimana salah satu pertimbangan utama pemilihan lokasi ini adalah ketersediaan bahan baku, lahan, dan nilai UMK tenaga kerja. Selain itu karena letaknya yang strategis untuk pemasaran karena berada di jalur pantura dan dekat dengan pelabuhan sehingga mempermudah proses pemasaran dan menjangkau konsumen yang sebagian besar berada di pulau Jawa. Dengan berdirinya pabrik sorbitol ini diharapkan dapat memenuhi pertumbuhan permintaan sorbitol di dalam negeri dan meningkatkan taraf hidup penduduk sekitar. Pabrik direncanakan beroperasi secara kontinyu 24 jam selama 330 hari pertahun operasi dengan perencanaan sebagai berikut :
a. Kapasitas produksi : 25,000 ton/tahun
b. Jumlah tenaga kerja : 174 orang/hari
c. Kebutuhan bahan baku tepung tapioka : 23,883.721 ton/tahun
Pabrik ini direncanakan mulai dibangun pada tahun 2022 di Kabupaten Pati, Provinsi Jawa Tengah dan direncanakan beroperasi pada tahun 2025. Modal diperoleh dengan perbandingan 60% modal sendiri dan 40% modal pinjaman. Pendirian pabrik sorbitol memerlukan biaya investasi modal tetap (fixed capital) sebesar Rp 573,847,492,601.965, modal kerja (working capital) Rp 101,267,204,576.817 investasi total Rp 675,114,697,178.782, biaya produksi per tahun Rp 350.446.235.485 dan hasil penjualan per tahun Rp 875,000,000,000. Dari analisa ekonomi didapatkan Internal Rate of Return sesudah pajak sebesar 36.9%, POT sesudah pajak 2.5 tahun, dan nilai NVP adalah Rp 710,576,712,199.866. Dari hasil uraian di atas, ditinjau dari segi teknis dan ekonomis, pabrik sorbitol dari tepung tapioka ini layak didirikan.
====================================================================================================================================
Sorbitol is a polyhydric alcohol monosaccharide compound. This compound is a sugar alcohol that is metabolized slowly in the body. Sorbitol is obtained by converting the aldehyde group to a hydroxyl group. The sorbitol industry is considered very strategic because sorbitol is widely used in various industries, such as the food, pharmaceutical, cosmetic, chemical and other industrial fields. Thus, the raw material for sorbitol has indirectly become part of daily needs. Sorbitol can be made in several ways from various types of raw materials, with different operating conditions and conversions. The manufacture of sorbitol from tapioca starch raw materials through two main process stages, the first stage is the process of changing starch (starch) into glucose using enzymes and the second stage is the process of converting glucose into sorbitol with a catalytic hydrogenation process. The sorbitol factory is planned to be established in Cilegon City, Banten Province. Where one of the main considerations for choosing this location is the availability of raw materials, land, and the value of the minimum wage for labor. In addition, because of its strategic location for marketing because it is on the north coast route and close to the port, it makes the marketing process easier and reaches consumers, most of whom are on the island of Java. With the establishment of this sorbitol factory, it is expected to be able to meet the growing demand for sorbitol in the country and improve the living standards of the surrounding population. The factory is planned to operate continuously 24 hours for 330 days per year of operation with the following planning:
a. Production capacity: : 25,000 ton/tahun
b. Number of workers : 174 men/day
c. Tapioca starch raw material needs : 23,883.721 ton/tahun
This factory is planned to start construction in 2022 in Regency of Pati, Central Java Province and is planned to operate in 2025. The capital is obtained with a ratio of 60% own capital and 40% loan capital. The establishment of a sorbitol factory requires fixed capital investment costs of Rp. 573,847,492,601.965, working capital of Rp. 101,267,204,576.817, total investment of Rp. 675,114,697,178.782, production costs per year of Rp. 350,446,235,485 and annual sales of Rp. 875,000,000,000. From the economic analysis, it was found that the Internal Rate of Return after tax was 20.5%, POT after tax was 2.5 years, BEP 36.9% and the NPV value was Rp. 710,576,712,199.866. From the results of the above description, from a technical and economic point of view, this sorbitol factory from tapioca starch is feasible to establish.
