Abstract

Permasalahan yang terjadi di Indonesia yaitu konsumsi gula yang lebih besar daripada hasil produksinya yang menyebabkan ketidakmampuan indutri gula untuk memenuhi permintaan semua konsumen. Salah satu permasalahan yang terjadi disebabkan karena banyaknya bahan baku yang masih impor termasuk flokulan yang digunakan dalam hal ini yaitu flokulan anionic polyacrylamide. Anionic polyacrylamide (APAM) pertama kali di dunia dikembangkan melalui proses hidrolisis alkali. Sampai saat ini, teknologi sintesis APAM telah mengalami banyak pengembangan. Namun masih sedikit penelitian tentang flokulan anionic poly (sodium acrylate-co-acrylamide) mengenai pengaruh sifat polimer dan efisiensi penggunaannya pada proses pemurnian gula sehingga dilakukan penelitian lanjutan terhadap karakteristik flokulan untuk mengurangi biaya pada proses produksi gula. Pada penelitian ini dilakukan sintesis poly(sodium acrylate-co-acrylamide) sebagai flokulan yang akan digunakan pada proses pemurnian gula. Tahap-tahap yang digunakan yaitu menambahkan asam akrilat, akrilamida dan sodium karbonat yang kemudian ditambahkan dengan larutan NaOH. Tahap selanjutnya yaitu sintesis poly(sodium acrylate-co-acrylamide) yang dilakukan dengan atmosfer nitrogen selama 3,5 jam yang sebelumnya telah ditambahkan dengan ammonium persulfate. Penelitian ini dilakukan pada perbandingan konsentrasi antara acrylic acid dan acrylamide yaitu 40:60, 50:50, 60:40. Flokulan yang dihasilkan selanjutnya akan diuji FTIR flokulan, uji SEM flokulan, uji kecepatan pengendapan, uji pH, uji TDS, uji turbidity terhadap nira gula untuk mengetahui pengaruh dari penambahan flokulan tersebut. Pada percobaan yang dilakukan, didapatkan hasil gelatin yang paling optimal adalah flokulan poly(sodium acrylate-co-acrylamide) hasil paling optimum diperoleh pada perbandingan konsentrasi 50:50 dengan dosis penambahan 6 ppm, nilai kecepatan pengendapan sebesar 3,333 ml/menit, nilai pH sebesar 7,19, nilai TDS sebesar 520 ppm, nilai turbidity sebesar 34,5 NTU.

The problem that occurs in Indonesia is that sugar consumption is greater than its production which causes the inability of the sugar industry to meet the demands of all consumers. One of the problems that occurs is due to the large number of imported raw materials including flocculants used in this case, namely anionic polyacrylamide flocculants. Anionic polyacrylamide (APAM) was first developed in the world through an alkali hydrolysis process. Until now, APAM synthesis technology has undergone many developments. However, there is still little research on anionic poly-acrylamide regarding the effect of polymer properties and the efficiency of their use in the sugar refining process, so that further research on the characteristics of flocculants is carried out to reduce costs in the sugar production process. In this study poly synthesis (sodium acrylate-co-acrylamide) was carried out as a flocculant which will be used in the sugar refining process. The steps used are adding acrylic acid, acrylamide and sodium carbonate which are then added with NaOH solution. The next step is the synthesis of poly (sodium acrylate-co-acrylamide) which is carried out with a nitrogen atmosphere for 3.5 hours which was previously added to ammonium persulfate. This study was conducted on 7 comparisons of the concentration of acrylic acid and acrylamide, namely 0: 100, 20:80, 40:60, 50:50, 60:40, 80:20, 100: 0. The resulting flocculants will then be tested for flocculant FTIR, flocculant SEM test, settling speed test, pH test, TDS test, turbidity test for sugar sap to determine the effect of the addition of flocculant. In the experiments conducted, the most optimal gelatin results obtained were the most optimal flocculants of poly (sodium acrylate-co-acrylamide) results obtained in a 50:50 comparison with a dose obtained at 6 ppm, estimated speed of 3,333 ml / minute, pH value is 7.19, TDS value is 520 ppm, turbidity value is 34.5 NTU.
