Based on the value of MAPE, MAD and MSD that forecasting VCT was suitable to used Double Exponential Smoothing Holt.  Double Exponential Smoothing Holt with α (alpha)=0.710 and γ (gamma)=0.039can produce MAPE=26.06, MAD=24, 75 dan MSD=1999.59 produce forecasting for the year 2018, Ft + m = St + btm F57 value + 6 = S57 + b56, obtained results for the month of January of the year of 2018 244.769. The number of people living with HIV was  recorded through VCT fluctuating but trends to rise over time. The value of forecasting has grown trend. For other researchers, because this research is univariate case, more comprehensive should added with other variables.
