Abstract: The contribution of dyadic coping to marital satisfaction for wives in Bukittinggi City during the covid-19 pandemic. This study aims to determine the contribution of dyadic coping to marital satisfaction for wives in Bukittinggi City during the pandemic. The selection of a pandemic as the focus of this research because the pandemic period produces a lot of stress in family. The participants of this study were 67 married women aged of 22-51 years in the Bukittinggi City. Sampling using incidental sampling technique. The instruments used are the Dyadic Coping Inventory adaptation scale by Yuliana & Valentina (2016) and the marriage satisfaction scale by Hermaleni (2018). The data were analyzed in the form of a simple regression test. This study shows that dyadic coping is predicted to contribute to marital satisfaction. This is obtained from the results of the simple regression significance test which shows a significance value of .000 (p˂.05).Abstrak: Kontribusi dyadic coping terhadap kepuasan pernikahan pada istri di Kota Bukittinggi selama masa pandemi covid-19.

This research aims to form a mathematical model in the problem of optimizing the average yield of cassava and soybean yields in West Pasaman Regency based on data from the West Pasaman Statistics Agency from 2007 to 2017 regarding the harvest area and average production of cassava and soybeans. The solution to the average production optimization problem uses the Wolfe's Method of Quadratic Programming. Wolfe method is used using a two-stage simplex iteration. The mathematical model formed is a non-linear equation. The estimation of parameters in the mathematical model uses the least squares method, which is calculated using the Matlab software. Optimization results using the Wolfe Method Quadratic Programming obtained an average of 340.95 kw / ha of cassava and soybeans, with an optimal harvest area of 255.38 ha of cassava and 469.5 ha of soybean harvest area.
