“…Both hemicellulose monomers can only dissolve in alkaline solvents with high concentrations [8]. Overall the xylan obtained is white, thus indicating that the xylan produced is in accordance with research conducted by Wirawan, et al [7] that the xylan from corncobs was white.…”

“…According to Ayunda., et al (2013) in Nurhidayah (2017) [9] tensile resistance is directly proportional to density, meaning that the higher the density will be followed by high tensile strength, for that pressing factor is very influential in increasing the value of paper tensile strength, wherein this study the variables neglected pressure. The results are obtained in accordance with previous research which states that the addition of xylan can increase the number of bonding networks between fibres which ultimately increases the strength of the sheet [3,7].…”

“…The tensile strength of paper in making paper made from used paper will decrease due to the recycling process. To increase the strength of the recycled fibre which is brittle due to the recycling process it is necessary to add additives that can increase the number of bonds between the fibres [7]. Tensile strength is the resistance of the pulp sheet to the tensile forces acting on both ends.…”

“…Hemicellulose content of corncobs is the biggest composition after cellulose [6]. Research on extracting xylan from Corncobs has been done by Wirawan, et al [7] by comparing xylan cobs of corn with commercial xylan. The xylan extraction was carried out by the acid method, then the xylan samples were tested on the used Wave Paperboard (KKG).…”

Several Indonesian paper mills utilize used paper as feedstock as the price is much cheaper and abundant availability, but the strength of the paper product tends to decrease. Xylan which is extracted from corncobs is a potential additive for upgrading the quality by modifying the fibre surface. This research studies the effect of sodium hydroxide concentration for extraction to produce an acceptable strength of paper product. The extraction process is at temperature of 90°C for 2 hours in a stirred tank reactor and the xylan product is deposited with 10 N acetic acid at pH of 4.5 - 5.0. Using 16% of NaOH concentration, the extraction produces 21.82% yield of xylan. With addition of this xylan product at mass ratio between xylan and corncobs of 5% increases 30.1% of the tensile strength and 31.83% of the tire strength. The optimum concentration of the use of NaOH in xylan extraction was at 16% NaOH with the largest xylan yield obtained at 21.82%.

The recycling paper industry has a good potential market. The industry used recycled paper such as Old Corrugated Containers (OCC), Old Newspaper (ONP), mixed waste paper, and Sorted White Ledger (SWL) as raw material. In Indonesia, commonly, the industry got the raw material of about 50% by importing. The government provides regulation to ensure the sustainability of the industrial activity, that is the process of importing recycled paper and internal regulation to increase local raw materials. The objectives of the research were to study the chosen raw material for the recycling paper industry and to analyze the positioning strategy of consumption raw material for the recycling paper industry in Indonesia. This research used a qualitative description method by the Analytical Hierarchy Process (AHP) and Strength Weakness Opportunities Threat (SWOT) analysis. The data were obtained from a questionnaire distributed to the paper industry, paper researcher, and relevant agencies. Based on AHP, the strength criteria to choose raw material is the regulation and availability of raw material with values 0.323 and 0.243; and the alternative chosen is recycled paper raw material import. The result of SWOT analysis, the recycling paper industry in Indonesia, has an Internal Factor Analysis Strategy (IFAS) 0.05, and an External Factor Analysis Strategy (EFAS) - 0.03. That showed from SWOT quadrant matrix, the position coordinate point of IFAS and EFAS in quadrant II. That means the positioning strategy is diversification. The government, recycling paper industry, and relevant agencies to corporate to increase the collecting rate of recycled paper.
