Abstract

This study aims to determine differences in zooxanthella density based on the life forms of coral Acropora Branching, Submassive Acropora, Branching, Foliose, Heliopora and comparing zooxanthella densities between the forms of coral form. This study was conducted in January-February 2020 on Marak Island, Nagari Sungai Pinang, West Sumatera Province. Zooxanthella density was calculated at the Marine Biology Laboratory, Department of Marine Sciences, University of Riau. The survey methode was used in this study, where the data collected was primary data. Coral Sampling was done by free collection using the SCUBA (Self Contained Underwater Breathing Apparatus). The result of study in the waters of Marak Island, West Sumatera on Acropora Branching corals were in the range of 0.004-0.13×106 cells/cm2. Acropora Submassive range of 2.95- 3.56×106 cells/cm2. Branching range of 2.41-2.59×106 cells/cm2. Foliose range of 0.44-1.09×106 cell/cm2. Heliopora range of 1.30-1.59×106 cell/cm2. The highest zooxanthella density was in Submassive Acropora and the lowest in Acropora Branching corals due to different forms of growth and temperature influences. Different forms of coral growth affect the zooxanthella density on a coral and the success of coral growth depends on the zooxanthella density and the size of the corallite of each coral life form.

Abstract

The research was conducted on November 2019 with sampling at the sea waters of Dumai, Riau province. Further, analysis samples in the Marine Chemistry’s Laboratory on Marine Sciences Department in Fisheries and Marine Faculty University of Riau. Method used method of survey. The form of data collection is the primary data obtained from survey activities and observation data from samples that have been analyzed in the laboratory. The results of the study showed that the type of microplastic found in sea water and Senangin (E. Tetradactylum) is a type of microplastic fiber, fragments, and film. Microplastic pellet type was not finding in this research. The abundance of microplastics in seawater samples ranges from 333,3333-456,6667 particles/m3, while the abundance of microplastics in Senangin fish (E. tetradactylum) is 966,6667-1933,3333 particles/Ind.

Abstract

The existence of a corona virus epidemic or Covid-19 that lasted a long time in several countries, one of which in Indonesia has a negative impact on the Micro and Small Medium Enterprises (MSMEs). The impact that occurred was the decline in turnover due to the reduced number of buyers, where many MSMEs had to close their businesses. When entering the new normalcy era or the New Normal era, the SMEs will open their businesses again but get new challenges in terms of product innovation. Innovation is needed to make a business survive in the new normal era, one of which is innovation in terms of product types. The purpose of this study is to produce recommendations for SMEs in determining the right product innovation strategy in the New Normal era. This study raises the formulation of the problem of how the SME product innovation strategy in the current era of New Normal. The method used in this study is a qualitative research method with data collection techniques through network interviews and descriptive data analysis techniques, with research informants who are SMEs in East Jakarta. The results of this study indicate that in the New Normal era, the SMEs are implementing a product innovation strategy by changing the shape of the product in the same type (changing shape) and also changing the type of product that is different from the previous product (changing type). By implementing the two product innovation strategies, SMEs can still compete in the New Normal era at this time. Recommendations from this research are expected to be used by SMEs to be more innovative in producing culinary products so they can survive in the New Normal era.
