This study aims to formulate an action plan of modern irrigation at Cibinuangeun. Cibinuangeun is an irrigation area located in Banten Province, Indonesia. The area is situated in a sediment area, so the land is very fertile. Cibinuangeun priory irrigated 2.809 hectares area which was distributed in 10 villages. Unfortunately, due to the lack of water, the area is dropping off. It reduces into 1.786 hectare and is only distributed in 4 villages. As a result, it influences the rice field productivity. Basically, the rice field productivity reached 5.17 ton/ha. Nowadays, it decreases to less than 5 ton/ha. This is lower than Indonesia national irrigation productivity which should reach 7 ton/ha. This condition indirectly indicates that there are relationship between rice field productivity and land area. Ninety five percent of rice productivity is influenced by the land area, and only 5% influenced by other factors, such agriculture intensifications. This means that the heightening of 1 hectares area can increase 4.91 tons of DMR. If irrigation area is expanded into 2.809, it can gain 5.024 tons of DMR. The farming income also will increase from 56.6 billion rupiah to 68.65 billion rupiah. Therefore, the intensification needs to be done. One of them is through the improvement of irrigation infrastructure and EM organization. © 2019 Published under licence by IOP Publishing Ltd.
