This study aims to analyze the relationship between employment opportunities and income before and during COVID-19. The research data collection is divided into two time periods, including January to March 2020 which is the period before COVID-19, while April to June 2020 is the period of during COVID-19. Each time period in this study analyzed 100 samples measured using a Likert scale. The method used in this research is simultaneous equation analysis with the Indirect Least Squares (ILS) approach. An important finding in this study for the period before and during COVID-19 is that employment opportunities are positively and significantly affected by infrastructure, economic conditions, government incentives and price stability. Meanwhile, income is positively and significantly influenced by employment opportunities, economic conditions, government incentives and price stability. Although the results of the research are the same for different time periods, based on the results of comparisons there has been a decrease in the contribution to employment and income during COVID-19. This study recommends that the government needs to maintain the stability of the indicators of employment opportunities and income used in this study so that turnover and community income do not decrease, especially during the COVID-19 period.

This study aims to model the welfare of fishermen's households in the coastal area of West Sumatra which is determined by the socio-cultural environment, catches and added value of 373 fishing households with fishing gear by using Partial Least Squares Structural Equation Modeling (PLS-SEM) approach. The contribution of this research lies in the concept of the socio-cultural environment in improving the welfare of fishermen's households through the catch and added value that has been ignored by previous researchers. The results of the study found that the fisherman household welfare model can be achieved through strengthening added value. This study suggests to the government to increase the added value of fishery products through the added value obtained from the difference between the selling price and the cost of materials or other supplies from fishing activities, fish farming, fish handling, fish processing, and distribution in a production process. Furthermore, this study suggests to further researchers to involve the study of the physical environment such as natural conditions as a determinant of the welfare of fishermen's households.
