1) There are cracks along the 11 meters wide 50 cm in 30 between the c.10 -c.11 segment. 2) There is still original soil erosion near the downstream drainage next to the emergency spillway. 3) The protective building of the instrumentation apparatus in the downstream area of the partially damaged partition (rock pairs on the loose wall) and part of the protective cover is lost. 4) Drainage system overgrown with weeds and there is damage to the lining of stone pairs. 5) The position of the right collector building is not suitable, the drainage channel is higher than the position of the container tub. 6) Grasses and herbaceous plants are still visible in several places on the sidelines of the hill and downstream of the dam, rip-rap hillsides and rafting downstream. 5. RESEVOIRS RIM INSPECTION In general the condition of the reservoir rim is relatively good and normal with the visual observation conditions as follows: 1. Found water vegetation in the form of water hyacinth in Cimanggu area. 2. There are many patches of illegal floating net cages in the Pasir Gombong Barat, Madang, Kertamanah, Pagadungan - Sukasari, Sukasari - Sodong, Cilendi and Jamaras – Tajur Sindang area. 3. More and more fishing rafts on the edge of the reservoir between the main dam – pasir gombong and Pagadungan area. 4. More and more non-permanent buildings and floating buildings in the puddle area and side of lake reservoir Sukasari, Cidadap, Cimanggu, Bojong, Warung Jeruk, Cilangobar, Sindang, Ciganea - Ubrug area, which is used by the community to trade and as a place of residence that has the potential to produce waste is relatively large. 5. Found erosion and landslides and landslide potential in the right bluff that is wide enough around the outlet Cirata reservoir. CONCLUSION Ir. H. Djuanda Dam is one of the largest dams and the first multipurpose dam in Indonesia. The dam with an area of 8,300 ha was built by the French franchise contractor Compagnie francaise d'entreprise in 1957 and completed in 1967, with a water potential of approximately 12.9 billion m3 / year. The capacity of this dam is 2.44 billion m3. 965
