PENGARUH JENIS BLEACHER DAN WAKTU PEMASAKAN TERHADAP PRODUKSI PULP DARI AMPAS TEBU DENGAN PROSES SODA

Sugarcane bagasse is an organic waste that is quite abundant with high levels of α-cellulose. However, bagasse has not been utilized optimally even though bagasse can be used as a raw material for making pulp. Pulp is the basic material in the manufacture of paper, where most of its production uses wood as basic materials. This study aims to identify sugarcane bagasse as an alternative raw material for pulping in terms of the effect of the type of bleacher and the length of cooking time. The type of bleach used is H 2 O 2 and NaClO and the cooking time is 30 minutes, 60 minutes and 90 minutes with the soda process. The results of the study showed that there was an effect of using a bleacher type H 2 O 2 with a cooking time of 90 minutes resulting in a higher pulp yield of 29.37%, compared to the NaClO bleacher at a cooking time of 90 minutes which only produced a pulp yield of 29.05%. The results of the FTIR test show typical absorption peaks such as the O-H phenolic functional group, C=O ketone absorption group, aliphatic –CH- and aromatic stretching groups. Identification of the lignin component produced by the pulp yield has an IR spectrum that corresponds to the IR spectrum of standard lignin components and Aldrich and Kraft commercial IR spectrum.
