Description
Summary:The study of atmospheric dispersion requires meteorological data from the nuclear reactor site. Parameter data that is very important to solve the atmospheric dispersion equation is weather stability. Weather stability, among others, requires solar radiation data. One way to measure solar radiation is to use an actinograph equipment like in BMKG Mempawah. The actinograph measurement results are curve, the edge of the curve is calculated using a planimeter to get solar radiation value. In this study, a code was developed to calculate the curve edge detection with phyton. The data used is Mempawah BMKG Station for one month periodical hourly on March 2021. The stages of processing the image to get the solar radiation value are pre-processing, processing and post processing. In the pre processing stage, the canny edge detection method is used to get the edge of the curve, as the basis to get solar radiation value. The regression model between the results of the planimeter calculation and the code has a correlation coefficient of 88.6 % with R-square of 78.5 %, which means that the result of the code calculations can explain the results of planimeter measurements of 78.5 %. Based on the result shows that canny edge method can be used to simplify the calculation of solar radiation. Further research with other method needs to be done to get better results. The Solar radiation value obtained from calculations using planimeter or code, based on table 1 is in the range between 175 – 675. The solar radiation value in meteorological data is used to calculate atmospheric stability
