A bar graph compares the number of vessels at Poso Port across different months. The horizontal axis represents the months from January to December, and the vertical axis represents the number of vessels, ranging from 0 to 25. The graph includes three data series: grey bars representing the difference, a blue line representing BPS Data, and an orange line representing Prediction Data. The grey bars show the difference in vessel counts for each month. The blue line indicates the official statistics reported by BPS Statistics Indonesia, while the orange line shows the estimates derived from the Distance-Based AOI algorithm. Notable trends include a peak in vessel counts in December for both BPS Data and Prediction Data, with the blue line showing higher values overall compared to the orange line. The grey bars vary in height, indicating the discrepancies between the two data series each month.Comparison of the number of visits at Poso port according to BPS and calculation results using the distance-based AOI algorithm
