Abstract

Dengan kadar selulosa yang tinggi, fiber cake kelapa sawit dapat digunakan sebagai bahan baku pembuatan nitroselulosa. Percobaan ini bertujuan untuk menghasilkan nitroselulosa dari ?-Selulosa fiber cake kelapa sawit yang memiliki yield produk dan kadar nitrogen yang tinggi dengan waktu yang singkat. Percobaan dilakukan melalui tiga tahapan yaitu tahap pre-treatment bahan baku, tahap pembuatan nitroselulosa melalui proses nitrasi dan tahap analisis produk nitroselulosa. Konversi ?-selulosa fiber cake kelapa sawit menjadi nitroselulosa dilakukan dengan variasi asam penitrasi dengan perbandingan H2SO4 98% dengan HNO3 70% sebesar 1:1, 1:2, 1:3, 1:4 dan 1:5, waktu reaksi pada proses nitrasi selama 30 dan 40 menit serta variasi.suhu proses nitrasi 10-15oC dan 15-20oC. Dari hasil penelitian diketahui bahwa kondisi optimal proses pembuatan nitroselulosa dari fiber cake kelapa sawit dicapai pada rasio asam penitrasi sebesar 1:1 dengan suhu nitrasi 15-20oC dan waktu nitrasi selama 40 menit. Pada kondisi ini diperoleh yield sebesar 95,0% dengan kadar nitrogen sebesar 9,9%. With high cellulose content, fiber cake palm oil can be used as a raw material for the manufacture of nitrocellulose. This experiment aims to produce nitrocellulose from fiber cake palm oil which has high yield product and high nitrogen content. The experiment was carried out in three stages, namely the pre-treatment of raw materials, the stage of making nitrocellulose through the nitration process and the analysis stage of the nitrocellulose product. The conversion of ?-cellulose fiber cake into nitrocellulose was carried out by varying the acid nitrate with a ratio of H2SO4 98% with HNO3 70% at 1:1, 1:2, 1:3, 1:4 and 1:5, The reaction is in the nitration process for 30 and 40 minutes and the variation of the nitration process temperature is 10-15oC and 15-20oC. From the results of the study it is known that the optimal conditions for the process of making nitrocellulose from fiber cake palm oil are achieved at a nitrating acid ratio of 1 :1 with a nitration temperature of 15-20oC and a nitration time of 40 minutes. In this condition, yield of 95,0% was obtained with nitrogen content of 9,9%.

Abstract

The main objective of this research is to obtain the optimum composition of bioplastics from the main ingredients of starch, cassava husks and corncobs. In this research, cassava peel starch will be used as the basic ingredient, glycerol as a plasticizer, as well as the addition of PVA, cellulose and ZnO with different concentration variations, namely 0.4; 0.8; 1,2; 1.6 g. The manufacture of biodegradable plastic will be carried out using the melt intercalation method or phase inversion technique, namely the evaporation of the solution after the printing process on the glass plate. Then biodegradation and mechanical properties of bioplastics were tested. The results of this study obtained the optimum composition in sample D3 with the most variations in the addition of cellulose with the highest tensile strength test value of 6.008 MPa, 12% Elongation Test, 48.07% Young's Modulus, 91.6% water resistance and Estimated degradation time of 27- 34 days.
