Abstract 316L stainless steel is one of the metal biomaterials used in implant applications because it has excellent mechanical strength. To improve biocompatibility and activity metals, a coating on surfaces required. coated with hydroxyapatite using dip technique. Firstly, suspension was prepared by mixing 10 grams hydroxyapatite, 1 gram sago starch, distilled water certain weight which then ...

Sago is an essential source of starch for some regions in the third and developing world. However, sago processing industry has been producing a large amount waste, untreated waste usually disposed to nearest river. It not only leads environmental problem, but it illegal under Environmental Quality Act 1974. Since still high content, which 58%, can be converted value-added products such as poul...

Traditional method of sago starch extraction was a time and labor intensive process. The most laborious stage is pith disintegration which done by using hammer-like tools called pounder. However, the use rasping machine to disintegrate saving energy significantly. objective this study investigate effect teeth diameter cylinder rotation speed on performance type machine. In experiment, four vari...

Coconut processed products (coconut cream) are widely used in the food field. However, various ways, such as adding starch and surfactants still need to be made improve stability of coconut cream. This study aimed evaluate addition surfactant on cream its use an ingredient rendang spices. The separation milk into was conducted using cold method (4oC for ± 18 hours) separator method. After that,...
