Therefore, a novel antifouling based materials with the incorporation of nanotechnology has been developed for the prevention of biofouling in its initial stage through photocatalytic treatment.
In addition to that, very limited works reported the efficiency of these catalytic materials for removal of microbial pollutants or antifouling agent.

Micropropagation of Sumatran Frankincense (Styrax benzoin) Forest Plants Producing Bioactive Raw Materials for Medicine Isnaini Nurwahyuni1,a*, Manihar Situmorang2,b, and Riyanto Sinaga1,c 1Departement of Biology, Faculty of Mathematics and Natural Science, Universitas Sumatera Utara, Indonesia 2Department of Chemistry, Faculty of Mathematics and Natural Science, Universitas Negeri Medan, Indonesia aisnaini@usu.ac.id, bmsitumorang@unimed.ac.id , riyantosinaga@usu.ac.id Keywords: Micropagation, Styrax benzoin Dryander, Medicinal raw materials, Non-timber products, Mother plant Abstract.
Indonesia's tropical forests are very good for the growth and development of woody plants as producers of bioactive compounds that are used as medicinal raw materials.
Frankincense sap contains the chemical compound cinnamic acid and its derivatives which are used as raw materials for the cosmetics and pharmaceutical industries [9][10].
Styrax benzoin plant has high economic potential because it produces sap containing bioactive compounds as raw materials for medicine and cosmetics.
Methods Chemicals and Materials.

The fine raw materials would be produced through fully mixing and grinding.

Introduction With the development of new materials and maching technologies, more and more structural ceramic parts are used to substitute for metal counterparts due to their excellent physical, chemical and mechanical properties [1] .
But for super-precision ELID grinding of hard and fragile materials, owing to thermal deformation of machine tool, it's not correct.
