Abstract

Background: The global pandemic that has affected many parties, digital transformation in increasing connectivity, the speed of change, the modern world, and improving education around the world is one solution that can be done. Purpose: The purpose of this study is to describe the opinions of Indonesian students in distance learning during the pandemic coronavirus 2019 (COVID-19). Methods: The method used is the technique of accidental sampling and regression analysis with SPSS software ver.16. Results: 76.2% of distance learning with practicum is difficult to understand, 31.7% experienced boredom, 82.5% often experienced difficulties with signal difficulty, 47.6% had difficulties when using media, 60.3% more time-consuming learning activities, 69.8% more spend money. Conclusion: There are significant differences between X1-X10 and Y1 and Y2 as well as the influence during the (COVID-19) (X) on changes in learning before and after (COVID-19) (Y2).

Abstract

The fish cultivation system in several villages in Kalitengah District uses an overtime system, namely a fish cultivation system that is carried out within 1 year (12 months) without passing rice planting. The research objective was to determine the abundance of plankton and the status of water quality fish cultivation “sawah tambak” with overtime system in Kalitengah District Lamongan. This is a quantitative research using descriptive methods. Based on the plankton abundance value at Station 1,2 and 3, the waters in the overtime system of ponds are in the Eutrooph category, with the abundance value > 12,000 Ind / L. Meanwhile station 4,5, and 6 are included in the Oligotrooph category since its abundance <10,000 Ind / L. The diversity value is within the range of 0.714267-1.823 which include in the category of small diversity and low community stability because the value of 0 <H '<1.5. All stations are in a moderate level of pollution which the diversity index value is within the range of 1 <H '<3. The Dominance Index (D) is in the range 0.212-1.224, Station 1 has a high dominance value because of the dominant species, namely Batrachospermum. Water quality parameters at all stations such asthe temperature ranges between 28.8-34.2 0C; the pH 8.5-9.2; Dissolved oxygen 4-10.44 mg / l; ammonia 0.009-0.17 mg / l; phosphate ranges from 0.025-2.3 mg / l. From the measurement results, water quality parameters show a good value for the growth of aquatic organisms.
