Shrimp shells consisting of head and skin can be extracted to get a filtrate that is rich in protein and delicious taste. The shrimp shell powder is refluxed in 2 stages, the first without enzymes and followed by the reflux stage with enzymatic bromelain. The function of enzymatic extraction is to get a protein that has more shrimp flavor. The filtrate without and with the enzyme are made into filtrate then added with flour and spices to become shrimp flavoring powder. Products analyzed and tested are shrimp flavor and filtrate. Tests carried out were tests of protein content, water content, analysis with FTIR, GCMS, and TEM. The results of the filtrate contain 24.6% total protein in the condition of adding bromelain enzymes as much as 2% (b / b) at 55 °C. Analysis of functional groups flavoring consist of amines, carboxylic acids, alcohols and phenols, amides, and sulfates. The powder is evenly distributed (not agglomerated) between 1-8 nm with a dominant diameter of 6 nm of 26.1%.

Rice husk as a by-product of the rice milling process is a material that can still be processed to be a product that can be used in various applications. The potential for the commercialization ofrice husks is still hampered by its low economic value. By using the heating method using an inert gas,rice husk can be converted into a composite whichcontains mostly silica and carbon, a wellknown component with excellent adsorbent properties. In this research,the utilization of ricehusk into silica/carbon composites was done by using three different methods. Common heating under temperature of 800oC (S), heating process under temperature of 800oC using furnace equipped with inert gas (CS), and heating process under temperature of 800oC using furnace equipped with inert gas with addition of glucose solution (CSL) were carried out in order to obtain three different kinds of composite. Analysis and characterization using Fourier Transform Infra-Red and X-Ray diffraction were performed to observe the properties of the composites. As the result, CSL has the highest adsorption capacity and Langmuir’s model adsorptive behavior.
