| dc.description.abstract | Currently, the pineapple leaf paper that is produced by using local wisdom is 50 centimeters wide and 64 centimeters long. Therefore, the product of the Cooperative is small. And because the size of the paper is limited, they cannot be used for producing room divider, big umbrella, or big painting as per customer’s demand and the members of the cooperative cannot produce large sheet of paper.
The researchers, therefore, designed the Pineapple fibrous leaf sieving Equipment in order to produce large sheet of paper. The equipment consists of a square basin for washing leaf fiber, sized 185 centimeters, 10 centimeter deep, with a 90-centimeter high stand to support the basin and installed the mechanism to lift up the sieve that is used to take up the pineapple leaf fiber. The sieve is 150 centimeters x 150 centimeters which is the largest size possible because the leaf fiber washing must is done by hand. If the sieve is bigger, we will not be able to reach to the leaf fiber in the center.
Base on the experiment of pineapple leaf paper production by using the new equipment as compared to the paper production as per local wisdom by using 2.5 kilograms pineapple leaf fiber and the paper thickness shall be fixed at 0.35 millimeters, it is found that the production that use pineapple fibrous leaf sieving equipment takes 647 second on average and the production as per local wisdom takes 1,421 second on average. In other words, the equipment can help to reduce the time in paper production of 774 second or 54 %. Apart from that, the researcher produced the paper with different thickness by increasing the pineapple leaf fiber by 0.5 kilograms per one sheet of paper, so that there are more options to choose in order to match with various products. The amount of leaf fiber used in the production starts from 3 kilograms to 7.5 kilogram per sheet and the thickness of the paper is from 0.36 millimeters and the thickest paper is 1.2 millimeters thick, using approximately 7.5 kilograms of leaf fiber. If we use more leaf fiber for paper production, the paper will be overweight and it will be sagging. | en_US |
