<p align="justify"> <br /> <br /> The construction of the runway at Rendani Airport, Manokwari needs an embankment to reach the target elevation of +4.00 m. The design loads on the runway are aircraft load of 15 kN/m2 and 750 mm pavement load of 13 kN/m2. The construction will be built on top of a soft clay, and there is also several layers of sand. Soft clay has a large consolidation coefficient, and sand soil is also susceptible to liquefaction potential. Therefore, treatment is needed to shorten the consolidation time and to increase the safety factor to liquefaction potential. The analysis shows that the suitable treatments are using prefabricated vertical drains and stone columns. <br /> <br /> Stone columns are used to increase the soil’s resistance to liquefaction when earthquake occurs. The method of this treatment is to install columns made from material that has higher permeability and stiffness than the soil by creating holes and filling them with gravel material. To shorten the consolidation time, prefabricated vertical drains are used. The installation of prefabricated vertical drains will cause water to dissipate quicker, by shortening the length of drainage. The design will be done by manual calculation which will be compared to the results using Plaxis 2D software. <br /> <br /> The foundations of the terminal will also be designed. In this case, bored pile foundation is used to support the upper structure of the terminal. The foundation will be designed using LPile and Group software, and the reinforcement design of the foundation will be designed using PCA Column and manual calculation. <br /> <p align="justify">
