Development of Natural Materials Gondorukem with Petroleum Ether, Anchor with Water as Fossil Conservation Materials

Abstract

Fossil conservation is one form of efforts to preserve fossils through the maintenance and
preservation of fossils. The fossil conservation method commonly used by the Sangiran
Early Man Site Preservation Center is the rock conservation method. If a fossil is found
that is broken or cracked, it is necessary to attach it using an epoxy resin type adhesive.
In this study, the experiment that will be carried out aims to provide an alternative
adhesive material from natural materials used for joining fossils and to compare the
effectiveness of natural adhesives with existing adhesives, namely epoxy resin. Natural
materials Anchor and Gondorukem (Resina colophonium) have been used as conservation
materials in Sangiran. Petroleum has never been processed into a conservative solvent for
fossil conservation. Therefore, this study chose a petroleum solution to be used as a solvent
for the conversion material used to conserve fossils. The way to make adhesive from
natural materials using petroleum solution is to grind the natural ingredients into powder,
which is then dissolved in petroleum solvent before being applied to fossils.
