Abstract

The development of science and technology in the field of analysis and construction planning is currently increasing, especially foundations. The foundation is a building structure that is in direct contact with the ground. This is because the foundation serves to distribute the load of the building to the soil layer so that if it is deep planning and implementation is not done properly it will result in the failure of the structure above it. The development of a construction project such as the development of Madrasah Ibtidaiyah Miftahul Ulum which is located in the Duduk Sampeyan District of Gresik Regency requires many things to support from planning to implementation. The foundation used in the construction of the Madrasah Ibtidaiyah Miftahul Ulum building is a type of strauss foundation. The reason for using a strauss foundation is because of the cohesive soil condition so that there is a potential for foundation settlement to occur so that researchers feel the need to use this type of foundation. The structural planning will be analyzed using the STAAD Pro program. In this study, the results of the vertical loading analysis obtained a maximum vertical force value of Pu of 454.04 kN, Mux of 0.000049 kNm, and Muy of 0.99 kNm. In addition, the dimensions of a strong pile cap to withstand the load used reinforcement 16 x 200 mm with a pile cap type PC7 with dimensions of 0.45 m x 0.45 m and PC11 with a pile cap shear strength is 465,564 kN.

Abstract

Asphalt is one of the materials used as road pavement material, this material was chosen because of its good and comfortable final result as flexible pavement. One way to prevent damage to the pavement due to vehicle loads is to improve the quality and stability of the pavement. Therefore, the use of additives is an alternative. Plastic basic materials that are difficult to decompose need to be handled properly in addition to recycling solutions with an increase in their functional value. Utilization of plastic waste as an additional material in the AC-BC (Asphalt Concrete-Binder Course) layer mixture in order to increase its stability value, as well as one of the concrete steps to reduce waste that is difficult to decompose by increasing its function value. In this function value. In this study, the addition of PET (Polyethylene Terephthalate) plastic to the AC-BC asphalt mixture affected the value of the marshall characteristics. With the effect caused by the addition of PET plastic, the higher the percentage of the mixture, the higher the percentage of the mixture, the higher the stability, VMA, VIM, and MQ values formed. Meanwhile, the value of VFB and flow tends to decrease as the PET plastic content increases. The percentage of addition of PET plastic to the AC-BC asphalt mixture also affects the density value where the higher the percentage value, the lower the density value and can increase the VIM value. So that the asphalt mixture will visually have a lot of voids.
