Abstract

This study stems from a question: “How should the foundation of a 2,000 m3 water tank be designed using standard penetration test (SPT) data for earthquake loads in accordance with SNI 1726:2019?” With a capacity of 2,000 m3, this tank has a significant volume and weight, making foundation analysis, especially regarding the effects of earthquakes, crucial, given that Indonesia is a region with high  activity. SNI 1726:2019 provides technical guidelines for earthquake-resistant design for building and non-building structures, including tank foundations. The objective is to determine the detailed dimensions of a foundation that can withstand earthquake loads in accordance with SNI 1726:2019, thereby obtaining the dimensions of the pile cap along with the required reinforcement details, as well as the sufficient bearing capacity of the piles based on standard penetration test (SPT) data. To determine the bearing capacity of the piles, the empirical formula proposed by Terzaghi and Mayerhof is used. The planning results yielded pile cap dimensions of 1600 cm in diameter and 80 cm in thickness, using fc' 30 MPa concrete and D19-150 threaded reinforcement steel. There are 50 pile foundation points with 50 cm diameter spun piles at a depth of 16 m.

Abstract

Iker-iker Geger Village is a village located in Cerme District, Gresik Regency. that often experiences seasonal flooding due to rainwater runoff that cannot be absorbed optimally by the soil, especially during high rainfall in the rainy season. The flat topography, clay soil type, and suboptimal drainage system exacerbate this condition. In addition, household organic waste management in the village is still limited, with most waste being burnt or dumped into waterways, contributing to drainage blockages and environmental pollution. These problems require a simple yet impactful approach, one of which is through the application of biopore infiltration pit technology that has proven effective in increasing groundwater absorption, reducing the volume of surface runoff, as well as processing organic waste into compost that is beneficial for local agriculture. This community service program aims to provide education and direct assistance to the people of Iker-Iker Geger Village in making and utilizing biopores as a sustainable environmental solution. This activity involves elements of the community, village officials, and students, with a participatory approach that is expected to increase environmental awareness and encourage village independence in overcoming the problems of inundation and organic waste. Through this program, the community not only gained technical skills but also instilled a spirit of mutual cooperation in protecting the environment, in line with the principles of sustainable development and local wisdom.
