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.

Abstract

The rise of clinical activities is one of the health care facilities that have the potential to pollute wastewater on organic compounds and especially pathogenic microorganisms. Technology in reducing organic and pathogenic content using combined ultraviolet filtration in wastewater treatment systems is one the effective method. Filtration uses activated carbon and silica with a variation of the ratio 2:3 and 3:2, while ultraviolet use a power variation of 9 watts and 15 watts. The results obtained are the best composition from the filtration process, which is a ratio of 2: 3 with the ultraviolet process using 15 watts using an exposure time of 5 hours with the remaining total coliform as much as 200 MPN/100mL. The results of this research have complied with the quality standards.
