inspection of ground and water inspection objects, such as dam surfaces, auxiliary buildings, ridges and reservoir cliffs, hydromechanical equipment and so on. The work of this inspection is a work performed by visual inspection method based on the March 2003 Safety Dam Inspection and Evaluation Guidelines published by the Ministry of Public Works. The steps taken against a finding on the ground during the visual inspection are S I M P L E i,e: a. Sketch: Drawing / Sketch that describes a finding in the field. b. Investigate: Investigate further on a finding in the field. c. Measure: Measuring dimensions of a field findings such as cracks, avalanches, leakage discharge and so on. d. Photograph: Take a picture / photo of a finding in the field. e. Locate: Marking the location / place of a find in the field is associated with easily recognizable objects such as shear, piezometer, Observation Well and so on. f. Engage: Engage experts or engineers who are experienced in visual inspection to be a resource person in consultation every problem that exists. The tools and materials commonly used in visual inspection at Ir.H.Djuanda Dam include : Four-wheeled vehicles, camera, handy cam, meter tool 50 m and 5 m, stationery, handbags, cranes and steel cages as a means to descend to the bottom of the spillway during Hollow Jet Valve inspection, belt safety (Safe Belt) for Hollowjet Valve inspection, buoy (Life Vest) for Rim Reservoir inspection, boat (Speed Boat) for inspection Rim Reservoir, handheld GPS (Global Positioning Tool). 1.1. DAM IR. H. DJUANDA Located approximately 100 km southeast of Jakarta and 60 km northwest of bandung, Ir. H. Djuanda dam is a new urugan dam with clay core, irin (Rock Fill with Inclined Clay Core). It has four saddle dam (saddle dam), namely the saddle dam of Pasir Gombong Barat, Pasir Gombong Timur, Ciganea, and Ubrug. The main spillway shaped tower type of morning glory, which at the bottom also functions as a powerhouse, as “Fig.1”. 959
