Continuous development causes changes in land use from open spaces as water catchment areas to become residential areas. The change in function of water catchment land causes rainwater that falls on the land not to enter the soil, but overflows on the surface of the soil. During the rainy season, most of the water will be discharged directly into the sea, otherwise it will cause puddles and flooding. Meanwhile, during the dry season, many groundwater sources experience drought. Naturally, groundwater shortages can be overcome if the management system is handled properly.The formulation of the problem in this study is how to apply infiltration wells to control rainwater puddles in residential areas.The working principle of an infiltration well is to distribute and collect rainwater into a hole or well, where the rainwater on the ground will then slowly seep into the ground. Below the ground, this seeping water will seep into the soil layer called the unsaturated layer, where this layer can still absorb water. Thus, the entry of rainwater into the ground will increase groundwater. The application of infiltration wells in residential areas requires calculation of the area covered by buildings and watertight. The number of infiltration well areas that need to be made is 4% of the watertight area.

The current competition among banking institutions has made customers more careful in choosing trusted banking institutions. If the customer gets a service that is not in accordance with what is desired, the management can lose customer confidence. In the end, customers will look for other banking institutions. This is a loss for management. Management should improve service quality to continue to gain customer trust and can continue to grow. Therefore, banking institutions need to create a Service Standard for the minimum implementation of banking services that are in accordance with the wishes of customers. This study aims to determine the standard of service that is in accordance with the wishes of customers and to prioritize the quality of service improvements that should be given to BRI bank customers at the Bangli office. The approach taken is the Kano method to categorize customer desires into the Kano category, the Quality Function Deployment (QFD) method to translate customer desires into what must be produced by bank management and the Resheniya Izobretatelskikh Zadatch (TRIZ) Theory method to improve mutual technical responses contradict. This study uses a questionnaire as a research instrument. Through the results of questionnaires it is known that 10 desires are needed by customers and are grouped based on 3 dimensions of Canoe. The results of categorizing attributes with Kano show that there are still categorized attributes as must be and one dimensional, meaning that there still needs to be a form of improvement from the management of the bank. From the formation of the House of Quality (HOQ) matrix, it is known that the variable "documentation and information" is the first priority in efforts to improve with the highest importance level of 19.58% and difficulty level 13.10%.
