Development of thermal insulation material using coconut fiber to reuse agricultural industrial waste

Abstract

This paper aims to report a development of thermal insulation material using coconut fiber, which is one of agricultural industrial waste in Indonesia and a verification of an effect of thermal insulation. Seven test pieces were developed under various conditions (amount of fiber, two types of binder, amount of water, temperature setting and drying time) and thermal properties such as thermal conductivities were measured using microcomputer "Arduino UNO" equipped with radiation thermos-camera. As a result, the insulation material which mixed 30g of the coconut fiber, 30g of tapioca starch and 300ml of water, drying under the setting temperature of 120 °C for 24 hours showed the lowest conductivity of 0.104 Wm-1K-1.
