Abstrak (PERENCANAAN BANGUNAN PELIMPAH (SPILLWAY) BENDUNGAN GINTUNG)

Akhirnya jadi juga Abstrak TA gw yang bakal gw sidang-in tanggal 8 Agustus nanti , semoga bisa lulus dengan hasil yang memuaskan.

Situ Gintung there is one there that works for water tourism, flood control and conservation of water resources around Jakarta. Situ built since 1932 it has burst its banks resulting in 94 fatalities. One cause of the breakdown Situ Gintung the spillway is not sufficient capacity to drain the Flood March 27, 2009 resulting in overtopping the channel wall above this resulted in the elevation of water level occurred in Situ Gintung burdening the embankment beyond capacity and is also coupled with the reduced strength of the embankment due to the establishment of housing around embankment. So need for planning buildings that can bestow spillway water in flood conditions. Type spillway planned are two types of saws with 1 m wide door in every door in the left side of the building spillway. From the calculation of flood discharge planning with the 1000 plan year (Q1000) of 128.845 m3/s obtained spillway building dimensions with effective width (the length of one sawtooth) 20.53 m, the peak elevation spillway building on 97.5 + with a base of the building elevation spillway at +90. For the planning pool used eddy USBR Type III column with a length of 13.8 m. The eddy field From the calculation of stability in earthquake and flood conditions spillway empty buildings earthquake safe to bolster stability, shear stability, carrying capacity and stability

Keyword : Spillway, plan, labyrinth spillway

Situ gintung merupakan salah satu situ yang berfungsi untuk pariwisata air, pengendalian banjir dan konservasi sumber daya air di sekitar Daerah Khusus Ibukota Jakarta. Situ yang dibangun sejak tahun 1932 ini mengalami jebol yang mengakibatkan 94 korban jiwa. Salah satu penyebab jebolnya Situ Gintung yaitu Saluran pelimpah tidak cukup kapasitasnya  untuk mengalirkan Banjir 27 Maret 2009 sehingga terjadi overtopping diatas dinding saluran hal ini mengakibatkan terjadi peninggian muka air di Situ Gintung yang membebani tanggul melebihi kapasitas dan juga ditambah dengan berkurangnya kekuatan tanggul akibat didirikannya perumahan disekitar tanggul. Sehingga diperlukannya perencanaan Bangunan pelimpah yang dapat melimpahkan air pada kondisi banjir. Tipe pelimpah yang direncanakan adalah tipe gergaji dengan 2 pintu selebar 1 m disetiap pintunya yang berada di sebelah kiri bangunan pelimpah. Dari hasil perhitungan perencanaan dengan debit banjir rencana 1000 tahun (Q1000) sebesar 128,845 m3/s didapatkan dimensi bangunan pelimpah dengan lebar efektif (panjang satu gigi gergaji) 20,53 m, elevasi puncak bangunan pelimpah pada + 97,5 dengan elevasi dasar bangunan pelimpah pada  +90. Untuk perencanaan kolam olakan digunakan kolom olakan USBR tipe III dengan panjang kolam olakan 13,8 m. Dari hasil perhitungan stabilitas pada kondisi banjir gempa dan kosong gempa bangunan pelimpah aman terhadap stabilitas guling, stabilitas geser, dan stabilitas daya dukung   

Kata Kunci : Bangunan pelimpah, perencanaan, pelimpah tipe gergaji

Indonesia, Negara ke-5 dengan sumber daya air terbanyak

Negara Indonesia ga boleh kekeringan atau kekurangan air bersih. Kenapa? karena "Give" yang diberikan oleh Maha Kuasa kepada negara Indonesia dan bidang sumber daya air itu begitu besar terbukti dari penelitian bahwa negara Indonesia merupakan negara ke-5 dengan sumber daya air terbanyak. Dalam hal ini dilihat dari jumlah curah hujan, aliran air bawah tanah, dan aliran air permukaan. data (sumber : CIA.gov) tersebut dapat dilihat dari tabel dibawah ini :
