“…Meanwhile, as many as 79.71% had never heard of the phenomenon of climate change, although they felt the impact of climate change. These results differ from previous research that workers' knowledge of climate change is in the high category with many workers stating that the current climate change has an adverse impact on paddy rice farming activities [15].…”

Climate change has become a global environmental issue that impacts all sectors of life, including agriculture. This study aims to determine workers’ knowledge of climate change in Karang Anyar Village Hamlet VII A Beringin Sub-district and workers’ anticipation strategies in reducing the adverse effects of climate change. This study used a qualitative approach. Informants were selected based on the criteria of wet-rice workers who have been farming for ten years by implementing semi-organic farming. Data were collected through interview techniques and literature study. Data analysis was conducted using the descriptive analysis method. The study results showed that workers know about climate change limited to seeing natural signs. Adverse impacts of climate change include a decrease in rice productivity. Workers anticipate reducing the adverse impacts of climate change by using rice varieties that are resistant to climate change, reducing the use of chemical insecticides and vegetable pesticides, and implementing a sustainable agricultural system.

This study discusses the dynamic analysis of the mathematical model of the spread of COVID-19 using daily cases in Indonesia which are classified into four variables, namely, Susceptible (S), Exposed (E), Infected (I), and Recovered (R) which are then analyzed dynamically by calculate the equilibrium point and look for stability properties. The two equilibrium points of this model are the disease-free equilibrium point and the endemic equilibrium point . Then, it is linearized around the equilibrium point using the given parameters. Linearization around the equilibrium point produces four eigenvalues, one of which is positive. Linearization around the equilibrium point yields two negative real eigenvalues and a pair of complex eigenvalues with negative real parts. Phase portraits and numerical simulations have shown that all variables S, E, I, and R will be asymptotically stable locally towards the equilibrium point, namely the endemic equilibrium point . Thus, based on the dynamic analysis obtained, it is shown that the disease-free equilibrium point is unstable and the endemic equilibrium point is locally asymptotically stable.
