Determination of Parameters for Production Process Using Raw Used Paper for Producing Quality Fancy Papers

Garbage is a consequence of human activities, every human activity must produce waste, the amount or volume of waste is proportional to the level of human consumption of goods / materials used daily. Likewise, with the type of waste, it really depends on the type of material consumed, therefore waste management cannot be separated from the management of people's lifestyles. Waste problems have become a major topic, ranging from the smallest environment to the large scope, many things that cause this garbage accumulation, but certainly the individual factors are very influential in this. There are two types of garbage, namely organic waste (commonly referred to as wet waste) and inorganic waste (dry waste). One of them is inorganic waste. Telkom University, one of the educational institutions that donates paper waste is quite potential, whether it comes from former concepts, correspondence or ex-exams, especially semester exams which are not taken by students. The used paper contains cellulose, hemicellulose, lignin, pectin, wax and miscellaneous, this content makes it possible to make art paper (fancy paper). Experiments carried out were scrap paper cut 3-5 cm in length with a cutting machine. Each batch uses 3 kg pieces of scrap paper heated in water with a ratio of 1: 7 ingredients and solutions with the addition of sodium hydroxide with variations of 10% and 20%, soaking time 3, 6, 9, 12 and 24 hours. Furthermore, separation of black leachate with pulp is carried out thoroughly. The clean pulp is ground to form fibers (fibrillation) for 15-30 minutes, then filtered to determine the size of the pulp. The results of the pulp grinding process are brown, if the art paper will be colored it needs to be bleached before it is colored. The pulp is mixed with water in a ratio of 1: 20, then 1% tapioca is added. Finally, the pulp is printed in gauze molds of 150-200 mesh to the desired size, dried and the paper is ready to be used to craft art paper products. Some compositions between the weight of waste paper, soaking time, NaOH concentration, hot water and grinding time are intended to produce quality fancy paper. The optimum process conditions chosen depend on the fancy paper specifications desired to get thick fancy paper using a sample A process recipe with a composition of 10% NaOH, soaked for 3 hours and ground to pulp for 30 minutes, while to get thin paper with physical properties good enough to use a recipe for the K sample process with a composition of 20% NaOH, soaked for 3 hours and ground to pulp for 15 minutes.
