Abstract

The level of risk of drought in the DAS Siak can be known, by calculating the index for drought using Thornthwaite Mather method. This method emphasizes the importance of rainfall data as input and potential evapotranspiration as superficial, but it is also necessary parameters soil moisture and vegetation as listener. The relationship between rainfall and potential evapotranspiration shows the state of the showing period of drought month and and the wet month. In the drought month period the amount of rain water is not sufficient for the water used by the plant, resulting in a shortage of soil moisture. The relationship between soil moisture shortage by potential evapotranspiration yield drought index. The choice of location DAS Siak in this study in order to reinforce the Drought Disaster Risk Index Map Riau Province issued by BNPB. Climate variability analysis results showed a decrease in the average annual rainfall of 15.50 mm/yr and an increase in average annual temperature of 0.08 °C. Thornthwaite Mather method analysis results showed an increase in average drought of 3.99% every year. The highest level of risk of drought occurred in 2014 and 2015 with a duration of severe drought occurred from January to November.Keywords: drought index, Thornthwaite Mather

Abstract

Least square is a method of tidal harmonic analysis that ignores meteorological factors in analyzing and predicting tidal elevations. This study analyzes the accuracy of tidal elevation predictions based on the initial date of the simulation. The analysis used 15 days tidal data from Pelindo Port C, Dumai. Furthermore, the results of the study were compared with the results of the most recent study, namely predictions of tide admiralty 15 days in the same location. The results of this study indicate that the results of the 15 days least square method prediction are more accurate than the admiralty method. The RMSE value from the least square method calculation gives the smallest Root Mean Square (RMSE) value of 34,56 cm, while the admiralty method is 71,38 cm. The most appropriate time to take primary data in the field for the purposes of tidal predictions is at the beginning of the third week of each month in the hijri calender or when the half moon phase.Keywords : least square method, tidal prediction, RMSE
