Results show that more 37.73 per cent the respondents experienced income shocks due to the COVID-19 crisis. For the coping strategies for that time, the study found that 83.31 per cent of these B40 households buy goods in stores that offer low prices, 3.74 per cent borrow money from relatives or neighbours to continue survival, picking vegetables around the house area with 32.28 per cent and 26.9 per cent to do business online.
