2. IR H. DJUANDA VISUAL INSPECTION Based on the results of visual inspection and observation of the dam body and its complementary building, that in general the dam Ir. H. Djuanda relatively good and normal, with the condition of findings in the field, among others: 1. On the hillside there are several rip-rap rock spots happening dislocations, and found grass and shurbs plants growing on the sidelines of rip-rap stones. 2. On the slopes downstream on the sidelines still visible grass and shrubs that grow, the frequency of grass that needs to be reproduced so that the roots of the plant does not penetrate the body of the dam that could be the outlet of water seepage on the lining wall structure and lining paving blocks access road to the dock. 3. Generally the condition of instrumentation in the main dam is relatively good, but on OW5 protective wall made of concrete slab looks damaged and not closed. The accelerometer installed in the Access Gallery of the tool is damaged, the error sign continues and the voltage indicator panel shows 5.4 volts which should be +/- 11 volts. The condition of the surface monument has small damage to the slope 9surface monument) which is located at the upper lining of the dam top. 4. Conditions of drainage channels in some places at the foot of the dam and downstream areas appear to be clogged with soil, moss and grass so that the water flow cannot flow smoothly and inundated. 5. Rip-rap conditions are generally good, but need to be weaned and additions around the C2 sliding mark downstream. 3. TOWER MAIN TOWER AND ACCESS GALLERY INSPECTION Based on visual inspection and observation of the main spillway tower, Access Gallery and its complementary building. In general the condition of the main spillway tower and access gallery is relatively good and normal, with the condition of findings in the field, among others: a. The connection between the plates on the bridge ladder has already started to loose due to run out by rust. And at some point bridge paint floor has begun to fade, the handrail and steel rope reinforcement on the right and left side of the bridge looks still pretty good. b. There are cracks in the 3 concrete joints under the rails. Found the wild vegetation around joint 9 then on joint 11. Three Dimension Instrument (3D) Joint Apparatus looks rusty start and surface pin is not flat. The 3D Joint Apparatus protective cover is largely unlocked because the lock nut is missing. The sliding mark on the shoulders of the tower must be re-painted because the 962
