Abstract

A magnesium oxide and titanium (II) oxide nanocomposite, MgO/TiO2 was synthesized to improve its surface area thus its adsorption capability may be risen. The synthesis was applying sol-gel method, combining MgO and TiO2 nanoparticles with NaOH becomes a nanocomposite with higher surface area. The pH effect on adsorption were analyzed. The expectation of using MgO/TiO2 compared with TiO2 and MgO alone is it may react faster on an adsorption trial with remazol turquoise blue dye, and the TiO2 may give its photocatalysis ability to the synthesized material. Less acid the condition of the solution, the capability of the MgO/TiO2 catalyst on adsorbing the remazol turquoise blue dye will increasing. After 90 minutes, the photocatalysis rate surpass the adsorption rate and reach equilibrium.

Abstract

Indonesia as an archipelagic country has a very high wealth of aquatic resources with the level of diversity of aquatic ecosystems as the role of living organisms. Benthos is an organism that lives on the bottom sediment of a body of water. This organism lives relatively sedentary and cannot avoid contact with pollutants and its lifespan is relatively long, so that if there is a change in water quality and the substrate in which it lives, it will affect its composition and abundance. The purpose of this study was to determine the index of benthos diversity found in coastal waters. Klumpang, Labuan Bajo, East Nusa Tenggara, Indonesia. Therefore, benthos can be used as a bioindicator in observing pollution in water, especially on the Klumpang coast. The result shows that   Klumpang beach shoreline has a medium diversity index, adequate productivity level, balanced ecosystem, and medium ecological pressure. The three sampling points has Shannon-Wiener diversity index by 1.790, 1.589, and 1.309 by sequence. The unbalanced species distribution of the species may indicate an unstable ecosystem in the shoreline, as the impact of surrounding activities especially in the eastern side of the coast.
