The objective of this research is to determine the physical quality of food media, consisting of small plate, large plate and small bowl. The method used of this research is testing the water absorption and resistance of the food media’s temperature. The process of making a food media using a stainless steel mold which is heated using a food thermometer with 100   and a load of 10 kg as a pressure, then it is printed for 5 minutes with 4 times taking the data for each food media. There are two testing of food media, the first test is water absorption with 29.5  for 125 miles into a small plate, 200 miles into a small bowl and 250 miles into a large plate for 60 minutes, the average value of the water absorption test for the Non-woven food media consists of three forms food medias have 0.00  as the same result, meanwhile woven media such as small plate has 65.00 , large plate has 44.83 and small bowl has 66.68 .  Second test is resistance of the food medias based on temperature parameters. The temperatures used were 40, 60, 80 for non-woven food media consists of three forms food media which had few change after drying, while for woven food media consists three forms of food media had the same results, that is seepage (leaking) in the food media.

Brick is a building material that has a function as a room sealer. Its larger size, when compared to red brick, makes bricks more in demand in the market. Improving the quality of bricks needs to be done to meet the needs of the building. The use of added materials becomes one of the things that can be considered to improve the nature and quality of bricks. This research aims to find out the strong press and absorption of bricks with the use of coconut pellet fiber. The research was conducted experimentally with the manufacture of test objects in the laboratory. The test object used is in the form of a beam of 30x15x10 cm. The percentage variation of coconut fiber is 5%, 10%, and 15% of the weight mass in bricks. The tests carried out include a strong compressive and water absorption test with reference to the Indonesian National Standard (SNI). The results of water absorption tests obtained the optimum value in bricks with a mixture of 5% fiber which is 6% of the mass of the weight of the brick, while the minimum value is in the brick, 15% fiber, which is 10%. While the compressive strength results get the optimum value on the 5% fiber mix variation, which is 20.1 kg/cm², and the minimum value on the variation of 15% fiber is 8.8 kg/cm². From these results showed that bricks with coconut pellet fiber have not been able to improve the quality of bricks.

Water Absorption Test

Water absorption is an important physical performance index to measure the quality of architectural ceramics products.The difference of water absorption test results between different laboratories is large, which cannot truly reflect the quality status of products, restricting the quality improvement of ceramic products and restricting the development of enterprises.This paper mainly analyzes the testing technology of water absorption of ceramic tile, and finds that the technical level of testing personnel, test water and vacuum system of equipment are the main factors affecting the results of water absorption test, and puts forward relevant Suggestions, which provides a strong basis for improving the testing technology of ceramic tile in the laboratory.

Parameters for measuring the physical properties on this research are divided into three elements, including measurement of weight, water absorption, and density. This research was conducted from January to March 2018 to determine the physical properties of wood powder composites and bagasse. The manufacturing and testing process refers to the ASTM and JIS standards. Weight and density testing refer to the ASTM D 792 standard while the water absorption test refers to the JIS A5908 standard. The results showed that the density of wood powder was 0.4175 gr / cm3, and the bagasse was 0.3125 gr / cm3. Then, fiber absorption in units of volume to water and resin were 16.88% and 13.75% respectively. The results showed that the largest water absorption was found in composite wood powder 60% and bagasse 40%, which was 13.47%, and for the highest density values found in wood powder composites as much as 80% or 1,078.29 kg / m3
