Abstract

In the effort of public welfare, the government through the provision of boards such as residential houses, either through private parties or SOEs, often gets the location of the land base in the form of soft land or ugly carrying capacity, which impact on maintenance and repair costs far greater than the cost of purchase. Researchers studied through the stabilization of soil with cement materials and soil mixed variations that occur, so that the soil as a buffer building is known strength or carrying capacity. On improving the strength of the road body with soil stabilization through the CBR test, it can be obtained an increase in soil bearing capacity. Sondir testing for the foundation design data either through conical resistance (qc) or by friction can be obtained by the base area of the foundation foot. If the value of qc is large then the footprint of the foundation foundation, especially shallow foundations will be small. With soil and cement stabilization studies in the laboratory, with different variations and durations can be obtained a reference to the increase in the carrying capacity of the shallow foundation footing and the required thickness of the layer based on the pattern of voltage distribution with the mathematical equation y = 0.7935x - 6.79 where y = power support for soil (kg / cm2), and x =% plus cement and R = correlation.Kata kunci: Tanah, Semen, Daya Dukung, Sondir.

Abstract

Darul Hikmah Mosque is a building located inside Politeknik Negeri Semarang as a place of worship for all campus residents, and people who live around the area. The prayer activity is preceded by the Wudu. In order for Wudu to be carried out perfectly, sufficient quantities of water are needed. The lack of pressure and discharge of Wudu tap water, when used simultaneously, becomes a constraint that is the water pressure decreases. The purpose of this study is to determine the factors causing the lack of water discharge or pressure as required in SNI 03-7065-2005. The research method is quantitative descriptive by evaluating the performance of the existing water supply system and using a discrepancy model by comparing the evaluation results with existing data to find discrepancies. Evaluation results indicate that the factors that cause the lack of water pressure are the roof tank height is less than ideal for water distribution with gravitational power, and the volume of available water is not sufficient
