Abstract

Macroalgae and Macroinvertebrata are marine biota scattered in the intertidal zone of Wawaran Beach Pacitan. Macroalgae and Macroinvertebrates are also organisms that are vulnerable to environmental changes that may affect its existence. The purpose of this research is to know the diversity of macroalgae and macroinvertebrate types found in Wawaran Pacitan Beach. This research method is descriptive qualitative. Methods of macroalgae and macroinvertebrate sampling using the roaming method. The sampling area is divided into 5 cruise stations drawn horizontally along ± 50 m from the intertidal zone. Determination of roaming stations based on visual differences of the substrate type.The results found 8 types of macroalgae from 3 Divisions, namely Division Chlorophyta 2 species, Phaeophyta 1 species, and Rhodophyta 5 species. Macroinvertebrates found there are 16 types of macroinvertebrates, namely from 12 species of Mollusca Phylum, Crustacean 1 species, and Echinodermata 3 species. Measurements of environmental parameters on Pacitan Wangi coast such as water and air temperature, salinity, DO, pH, current velocity, depth, and dominant visual substrate are sandy and cumbersome still appropriate for macroalaga and macroinvertebrate growth. Analyzing the results of the diversity index of macroinvertebrate types (H '= 2.25), the diversity is classified as moderate. The Columbella pardalina species are most commonly found on the coast of Wawaran Pacitan.Analysis of audio visual bias learning media for high school class X, 92.8% and 85.7%prersentage, which category of audio-visual media is very good that is suitable for use
