Experiment studies using waterfall stones and labu sayung to reduce the temperature of water based on concept of heat transfer

Abstract

This experiment is being held to determine whether labu sayong, which is made from clay, and waterfall stone were really able to reduce the temperature of water when it is filled in them. This is because we always heard peoples say that the water kept in labu sayong is always cooler than kept in the usual bottle and for the waterfall stone, when we go any waterfall area, we always feel that the water is cooler. So, to find out scientifically and technically whether these phenomena is truly happens, we decided to run this project and furthermore try to find out why it happens if its right. We also would like to make some value added recommendations using these natural resources, which is clay and waterfall stone into something such as natural cooling system as water tanks, chiller, or something valuable for money such as cement mixture to replace some costly material. By applying our knowledge in few experiments and do some analysis, we believe that something can be done to turn these natural resources into something which have market value.
