Jaya, Lukman Adhi (2011) Making Of Pulp From Musa Paradiciasa with a Digester. Undergraduate thesis, Undip.
Banana is often overlooked by most people and is considered a waste of banana trees, proved to have high fiber content which can be used as pulp. A suitable tropical climate and soil conditions that contain lots of humus enables banana plant is widespread in Indonesia. Currently, almost all parts of Indonesia is the banana-producing regions. The content of cellulose which is pretty much contained in this stem can be used as raw material for pulp. To find good operating condition to produce pulp from waste banana done some analysis includes the analysis of ash content, levels of α cellulose, lignin levels. Pulping of banana is done by experimental methods 1300C variable operating conditions remain unchanged while the concentration of NaOH variable with composition 90; 85; 80; 75; 70% and at different times of 3-4 hours. In experiments using materials banana pulp raw material containing cellulose α 59%, 57%, 54%, 48.7%, 46.3%. While standards for banana cellulose is 60-65%. From the lab I was still not optimal and do not meet the standard cellulose. This is due to a too low temperature 1300C and the time is too fast for 2-4 hours. So that cooking does not take place perfectly and the pulp is not degraded properly. While the optimal operating conditions is 4-5 hours and the temperature of cooking 165-1710C. From the experimental results obtained lignin content of 9.53%, 9.55%, 9.72%, 9.66%, 9.7%. While the lignin content standards for banana is 5-10%. Of the five types of pulp having a lignin content of the lowest (best) is the first pulp. This is because the first trial had the longest cooking time is 4 hours and a high level cooking is a solution of NaOH 90%.
