The mean-variance method introduced by Markowitz is considered as the fundamental basis of portfolio theory but the method introduced by Markowitz is only used for single periods while in reality Pension Fund institutions must carry out multi-period investment activities. Looking at the limitations of the mean-variance method introduced by Markowitz, research on portfolio optimization for multiperiods known as multiperiod mean-variance emerged. Based on these conditions, this study discusses about the application of the mean-variance multiperiod method carried out by Yao, Lai, Ma & Jian (2014) which considered mortality risk and changes in contributions. In this study using 4 scenarios using assets included in the LQ45 index as risk assets and T-Bill 3 months as risk-free assets during the 2014-2018 period. The results of this study indicate that the smallest return is owned by the asset allocation model without contributions (scenario 2) because there is no additional membership fee, so the amount of funds that can be invested is more limited so the expected wealth terminal is smaller than other asset allocation models. Then the asset allocation model without mortality (scenario 3) provides the highest expected terminal wealth compared to other asset allocation models, this is because in the absence of mortality factors the Pension Fund investment will not be forced to stop before the retirement period ends so that the portfolio return is higher than other models. While the asset allocation model using risk free asset references (scenario 4) has a higher risk with the same return when compared to asset allocation using reference to risk assets (scenario 3) this shows that the asset reference used affects the return and risk in allocation of Pension Fund assets at the end of the investment period.
