Abstract

Abstract Women in Penfui Timur Village as household financial managers mostly only depend on their husband's income which has been used or deducted by the Bank or cooperative because it is used to build a house or other business. However, some of them lack creativity in increasing other income or investing their husband's money in the form of small businesses or investments. Therefore, mathematics lecturers in collaboration with economics lecturers will provide enlightenment in the form of delivering materials and exercises and sharing experiences in terms of managing household finances fairly, wisely, and creatively innovatively. Our hope is that after receiving learning and sharing experiences from competent lecturers in mathematics and economics, women in Penfui Timur Village will be strengthened and have ideas in managing household finances efficiently and fairly and be creative in building alternative household businesses that of course see the market share to improve the economy in the home. With the aim that no family is lacking in material so that the next generation of the nation can go to school and have creativity with good nutritional value in order to achieve intelligence for all Indonesian people because they have parents who are diligent, creative, fair and wise in managing finances as a whole. Keywords: Mathematical concepts, Finance, Household, Creative, Entrepreneurship

Abstract

The objective of research is to assess the uniformity of pressure and the effectiveness of water distribution among the irrigation nodes. The study models drip and sprinkler irrigation networks in an 11,500 m² agricultural field using a hydraulic modeling technique using EPANET 2.2 software. The number of non-flow nodes in each simulated area, the minimum-maximum discharge, and the average pressure are the primary parameters that are examined. The findings demonstrate that branch diameter, pipe length, and pipe network layout all have a substantial impact on flow rate and pressure distribution. While locations with longer pipe segments encounter pressure drops of up to 5–7 mH₂O at the downstream portion, areas with homogeneous pressure (8–10 mH₂O) demonstrate more steady and effective water distribution performance. It was discovered that the main causes of system efficiency reduction were frictional energy losses and small losses. To increase pressure uniformity, pump energy efficiency, and overall irrigation system reliability, technical suggestions are made to install pressure regulator valves (PRV), optimize pipe diameter, and conduct zoning operations.
