The Kamijoro Dam is very useful to support increased agricultural production, especially to strengthen food self-sufficiency and supply of raw water. The authors redesigned the Kamijoro dam. Based on observations, there is a dam potential to increase its capacity and function by first redesigning the initial planning. In order to redesign the Kamijoro dam, value engineering analysis was applied. The value engineering results are compared with the initial design to obtain a better, more effective and efficient dam design. The way to compare it is to use the evaluation matrix method. From the planned peak length of the dam 161 meters, dam discharge of 13.171 m 3 / sec / m1, the fulfillment of raw water is 500 l / s with a project value of Rp. 188.799.932.000,-. Based on the analysis of technical values, by reducing the width of the dam, we obtained several performance optimizations. Among them are the dam spanning 125 peaks, flow rate of 17.90 m 3 / second / meter, raw water requirement of 600 liters / second and the project value of Rp. 183.229.730.000,-With a slight cost efficiency of the project value of about 2.95%, a more optimal dam function and performance were obtained.
