Abstract

Sebagai negara berkembang, Indonesia sedang meningkatkan pembangunan di berbagai bidang, termasuk sektor industri. Hal ini dikarenakan semakin bertambahnya jumlah penduduk, maka semakin bertambah pula kebutuhan pangan di Indonesia, salah satunya yaitu gula. Bahan yang dapat dijadikan sebagai pengganti gula yaitu sorbitol. Sorbitol disebut gula alkohol karena berasal dari reduksi glukosa. Kapasitas produksi sorbitol yang akan didirikan yaitu 35.000 ton/tahun. Proses pembuatan sorbitol ini menggunakan bahan baku tepung tapioka dan proses hidrogenasi katalitik. Lokasi pendirian pabrik ini yaitu di Pati, Jawa Tengah. Proses pembuatan sorbitol ini terdiri dari 4 tahapan yaitu tahap liquifikasi terjadi proses pencampuran dan gelatinisasi, tahap utama (dekstrinasi yaitu terjadi penambahan enzim α-amilase, sakarifikasi yaitu terjadi penambahan enzim glukoamilase, dan hidrogenasi yaitu terjadi penambahan gas hidrogen dan katalis Raney Nickel), tahap pemurnian (karbonasi yaitu proses penambahan karbon aktif untuk menjernihkan produk, filtrasi yaitu terjadi proses penyaringan antara filtrat dan cake, dan ion exchanger yaitu proses terjadinya penukaran ion positif dan negatif), serta tahap akhir (pemekatan larutan sorbitol 50% menjadi larutan sorbitol 75-80%). Pabrik ini akan dioperasikan secara kontinyu selama 330 hari/tahun dengan basis 24 jam/hari. Bahan baku tepung tapioka yang akan digunakan yaitu 61,531.41 kg/hari. Hasil dari proses ini yaitu larutan sorbitol 75-80%. Pada proses pembuatan sorbitol, dilakukan efisiensi dan optimasi yaitu menerapkan sistem MVR Single Efek Evaporator pada evaporator di unit sorbitol untuk menghemat penggunaan steam dari utility. Selain itu juga dilakukan pertukaran panas sensibel hasil kondensat evaporator MVR dengan produk yang masuk pada heater (E-242), sehingga penghematan steam dapat diaplikasikan secara optimal. Hasil dari efisiensi dan optimasi yang telah dilakukan yaitu dapat menghemat penggunaan steam dari utility sebanyak 87% dari total penggunaan alat yang memerlukan steam pada unit sorbitol dan dari segi analisa ekonomi lebih menguntungkan karena menurunkan nilai POT dan BEP yang berdampak positif bagi perusahaan

As a developing country, Indonesia is increasing development in various fields, including the industrial sector. This is because of the increasing number of people, the more food needs in Indonesia, one of which is sugar. The material that can be used as a substitute for sugar is sorbitol. Sorbitol is called sugar alcohol because it is derived from glucose reduction. The production capacity of sorbitol to be established is 35,000 tons/year. Making sorbitol uses tapioca flour as raw material and a catalytic hydrogenation process. The location of the establishment of this factory is in Pati, Central Java. The process of making sorbitol consists of 4 stages, namely the liquification stage where the mixing and gelatinization process occurs, the main stage (dextrination is the addition of -amylase enzyme, saccharification is the addition of glucoamylase enzyme, and hydrogenation is the addition of hydrogen gas and Raney Nickel catalyst), the second stage is the addition of hydrogen gas and Raney Nickel catalyst. purification (carbonation, which is the process of adding activated carbon to purify the product, filtration, which is a filtering process between the filtrate and cake, an ion exchanger, which is the process of exchanging positive and negative ions), and the final stage (concentration of 50% sorbitol solution to 75-80 sorbitol solution). %). This plant will be operated continuously for 330 days/year on a 24-hour/day basis. The raw material for tapioca flour is 61,531.41 kg/day. The result of this process is 75-80% sorbitol solution. In the process of making sorbitol, efficiency and optimization are carried out, namely applying the MVR Single Effect Evaporator system to the evaporator in the sorbitol unit to save steam from the utility. In addition, sensible heat exchange from the condensate of the MVR evaporator is also carried out with the product entering the heater (E-242), so that steam savings can be applied optimally. The results of the efficiency and optimization that have been carried out are that it can save the use of steam from the utility as much as 87% of the total use of tools that require steam in the sorbitol unit and from an economic analysis point of view it is more profitable because it reduces the value of POT and BEP which has a positive impact on the company
