Abstract

Echinoderms are in habitats in coastal waters because  is a biota that can maintain the sustainability and  the balance of the coral reef ecosystem. Human activity  in utili zing Echinoderms, namely in Echinoidea  and Holothuroidea can affect life  his life. The purpose of this study was to determine the diversity of phyla  Echinoderms class Echinoidea and Holothuroidea at the Harbor  Waingapu Old Pier and its use as a medium  Biology learning. The research method used is  purposive sampling and analyzed using the approach  quantitative descriptive with the Shannon diversity index formula  Wiener. Echinoderm samples were calculated using the technique quadratic transects with a plot size of 2 x 2 meters are placed perpendicularly  in the direction of 50 meters using a plot of 30  plot. Environmental factors measured are temperature, salinity, degrees  acidity (pH) and levels of oxygen (DO). Measurements are taken  at each observation station. The results showed 11 species  Echinoderms are divided into 2 classes, namely Diadema setosum, Diadema savignyi, Tripneustes gratilla, Strongylocentrotus  droebachiensis, Echinocardium flavescens, Clypeaster subdepressus,  and Mespilia globulus from the class Echinoidea. Holothuria atra, Holothuria scraba, Euapta godeffroyi and Chiridota rigida from the class Holothuroidea. The diversity index obtained includes  medium category with a value of H = 1.696.

Abstract

The provision of variations in the use of media equipped with methods in learning is carried out in order to attract students in learning during the Covid-19 pandemic which aims to find out the influence of the use of video learning media equipped with crossword puzzle type Student Worksheets (LKPD), on learning outcomes during the Covid-19 pandemic; This type of research is experimental research, using a mixed methods approach with the concurrent triangulation design method. The results showed that: (1) there was a positive influence on the use of video learning media equipped with crossword puzzle type Student Worksheets on learning outcomes, shown from the results of the hypothesis test, namely 0.000 or Sig values. < 0.05; (2) there are differences in student learning outcomes between the use of power point learning media (PPT) and video learning media equipped with crossword puzzle type LKPD, shown by the average posttest of the control class 56.56 and the posttest of the experimental class 82.76. It can be concluded that the use of video media equipped with crossword puzzle type LKPD has a positive influence on learning outcomes on human circulatory system material during the Covid-19 pandemic.
