Earth fill dam is a dam built by hoarding materials, such as: rocks, gravels, sand and soil on certain composition with the function as a contributor or an instrument for anchoring or lifting the water surface contained in the reservoir. The structure of earth fill dam is divided into three zones, namely core zone (impermeable), filter zone, and random zone (permeable). The material or material of the embankment in the dam is a local material from the early excavation of the dam. The material of the core (moisture) core deposits of red soil results from the excavation work at the dam site and must pass the test. The embankment material in the dam is local material from the early excavation of the dam. The material of the core zone (impermeable) is in a form of red soil resulted from excavation work at the dam and must pass the test. The core zone (impermeable) serves to withstand water seepage that passes from the random zone. Given these conditions, monitoring the implementation and dam construction material stocks are indispensable in order to get a good quality dams in accordance with the plan. The supervision of the implementation of the dam work is aimed to be in accordance with the planned method, while the monitoring of stock analysis of soil pile materials aims to make the pile material to be used is in accordance with the planning specifications before being used for the embankment material. Soil density value of embankment is an important thing which needs supervision to keep the density value stable
