The Ability of Coco Fiber Material in Reducing Heat as An Insulation of Building Walls on Accepted Temperature Level

This paper was purposed to determine the ability of coco fibers in reducing heat as a wall covering solution with different temperature levels. For the fulfillment of thermal comfort in buildings requires engineering, knowledge and skills and innovation. One way to reduce hot air in the room can be done through walls, thereby reducing the use of air conditioning. The walls need protection and solar heat absorbers that can make the room inside the building have thermal comfort. Based on this, research needs to be done on natural ingredients that can function to reduce heat. Tests carried out on coconut fiber and fiber-free materials. Material without fiber and coco fiber is 2 cm thickness of each. This coco fiber material is coated with a mixture of cement that also functions as a fiber adhesive. In this case, testing is conducted by applying heat of 60° Celsius and 40° Celsius to one side of the fiber and measuring the temperature that occurs on the other side of the fiber. The test results found that there was a significant difference between the heat temperature supplied and the heat temperature measured on coco fiber. The higher the temperature is received, the greater the heat that can be absorbed. This shows that coco fiber material has the ability to reduce heat at high enough heat as a wall covering against solar radiation.
