THE EFFECT OF THE ADDITION OF SUB-CEREAL BEACH PUMICE POWDER ON THE ENERGY CAPACITY OF BIOETHANOL FROM MANGROVE FRUIT WASTE ( Bruguiera gymnorrhiza ) IN PROVIDING CALORIES THROUGH THE TEMPERATURE TEST OF LIQUID SUBSTANCES WITH INDICATORS ON THE GLASS WICK

Abstract

Bioethanol energy is one of the natural and environmentally friendly renewable energy that plays an active role as a fuel to replace fossil energy in households. Bioethanol energy is made from organic compounds which in this case use mangrove fruit waste or Aiwon fruit (Bruguiera gymnorrhiza) in maintaining its quality by making the fuel not burn out quickly in its daily use. One of the efforts that can be made is to add sub-cereal type rubbing pumice powder which is also not difficult to get on the beaches of coastal villages. The purpose of adding sub-cereal type rubbing pumice to bioethanol renewable energy made from mangrove fruit waste (Aiwon) is to increase the duration of this bioethanol energy ability in providing energy to the affected object or the object undergoes a process of change. The writing method in this study is experimental and literature. The results of the study include: 1) Revealing the basic reasons for the availability of renewable energy bioethanol from mangrove fruit waste (Aiwon) provides heat energy to an object that is affected to undergo changes, especially changes in the temperature of liquid substances. 2) To reveal the difference in the duration of flames that use bioethanol energy with the addition of sub-cereal type rubbing pumice powder in the amount of pumice powder given varies or different amounts. So the conclusion is that by adding sub- cereal rubbing pumice powder with different doses, it will give a difference in the duration of the flame or provide calories when used to influence the change of an object in fulfilling household activities.
