Abstract

Mount Merapi (2980) meters above sea level, one of the most active volcanoes in the world, located in Central Java Province. Mt. Merapi last erupted in 2012, producing a large number of volcanic materials which has highly destructive force. This flow happened on almost all of the rivers in Mt. Merapi hillside, such as Kali Putih for example. Kali Putih has a big potential of damage because of its location, near rural areas. Reffering to the above mentioned, the preventive effort of disasterous effect need to be done to decrease the damages by building Sabo Dam. The data we need to design it are hydrological data such as annual daily rainfalls data and Kali Putih catchment area map, soil investigation data, a topographic map and geometric river map. Those data will be processed and used as the basis for designing the Main Sabo Dam, Sub Sabo Dam, Apron and etc. After the process of designing is completed, the results are: total height of Main Dam is 8,55 meters, total height of Sub Sabo Dam is 2,79  meters, length of Apron is 6,1 meters, sediment storage capacity is 8.100 m3, the total cost is Rp.1.470.615.000,00 (including VAT) and the construction period is 14 weeks. The construction of Sabo Dam will be more optimal if it is accompanied by a good maintenance system done by the related agencies, so that the percentage of the damaged covering areas will decrease significantly.

Abstract

The land use change of area sub-watershed Kreo potentially lead to an increase in erosion and sediment transport by river flow increases. Increased sediment transport in river flow can destabilize the river morphology Kreo such as a decrease in the riverbed Kreo (degradation), changes in river geometry vertical and horizontal direction, and the elevation of the riverbed (agradastion). To control the morphology of the river Kreo stability it need to be built sediment control structure (check dam). The design of sedimen control at Kreo river is located in the Village of Kali Pancur, District Ngaliyan. Kreo river have watershed area 65.58 km2 the length of the main river ± 30.60 km, the average river width of 14.6 m. Based on the calculations have been done better hydrological analysis, hydraulics analysis, planning dimensions check dams, control stability of main dam, and capacity analysis of sediment the river discharge plan obtained by 102 m3/s, check dam spillway base width of 20.5 m, effective height of the main dam 2 m, foundation depth of main dam, thick of mercu main dam 1.5 m, length of basin whirl 17 m, thick of basin whirl 0,6 m and sediment capacity is 14,911,55 m3 with the design life of 10.7 years. This project implementation is scheduled for 20 weeks with a budget plan of Rp. 2.340.000.000, -.

Abstract

Waduk Wonogiri terletak di bagian selatan Kabupaten Wonogiri. Sepanjang pengoperasiannya waduk ini mengalami sedimentasi  3,1 juta m3/tahun, aliran sedimen terbesar disumbang oleh Daerah Aliran Sungai (DAS) Keduang. Diperlukan upaya untuk mengurangi sedimentasi, antara lain dengan membuat saluran bypass agar aliran dengan konsentrasi sedimen yang tinggi dapat dialihkan sebelum masuk ke waduk. Perencanaan ini bertujuan untuk menentukan debit operasional, struktur dan dimensi penampang saluran bypass Sungai Keduang hingga rencana anggaran pembangunan. Metode yang digunakan dalam perencanaan ini adalah dengan melakukan analisis hidrologi melalui pendekatan konsep debit dominan dan angkutan sedimen sehingga dapat diketahui besarnya debit, waktu pelepasan, dan tingkat efisiensi. Berdasarkan hasil analisis yang dilakukan, volume air yang dilepas melalui saluran bypass rata-rata sebesar 482.044.742 m3/tahun, dan batasan debit operasional saluran bypass sebesar 10-30 m3/s. Dengan batasan tersebut dihasilkan tingkat efisiensi saluran bypass rata-rata sebesar 29,36%. Pengoperasian saluran bypass menggunakan pintu air tipe angkat dan pintu klep otomatis, dengan perkuatan sisi mengggunakan dinding penahan pasangan batu. Perkiraan nilai biaya pembangunan saluran bypass sebesar Rp 217.540.837.000 (dua ratus tujuh belas milyar lima ratus empat puluh juta delapan ratus tiga puluh tujuh ribu rupiah) dengan durasi pelaksanaan pekerjaan selama 37 minggu.

Abstract

Banjir yang sering terjadi di Kabupaten Demak disebabkan oleh meluapnya Sungai Dolok. Kondisi Sungai Dolok yang mengalami penyempitan alur serta pendangkalan menyebabkan berkurangnya kapasitas penampang sungai untuk mengalirkan debit banjir. Akibatnya, pada musim penghujan Kabupaten Demak sering mengalami banjir. Sungai Dolok memiliki panjang sekitar 47 km dan luas daerah aliran sungai sekitar 145 km2. Hidrograf banjir Sungai Dolok dianalisis dengan menggunakan program HEC-HMS dan untuk analisis hidrolika menggunakan program HEC-RAS. Hasil analisis menunjukan kondisi penampang eksisting Sungai Dolok tidak mencukupi untuk mengalirkan debit banjir Q50th sebesar 216 m3/dt. Akibatnya, terjadi bencana banjir di Kabupaten Demak. Dari studi dan perhitungan yang telah dilakukan, pemecahan masalah ini adalah mengadakan normalisasi Sungai Dolok dengan melakukan perbaikan penampang sungai Dolok yang sesuai perencanaan. sehingga Sungai Dolok dapat mengalirkan debit banjir dan mengurangi tingkat bencana banjir di Kabupaten Demak.

Abstract

Sedimentation is often happen in low-ground area. Where the minimum slope of the river caused a low-velocity in river flow. A low-velocity flow made the particles of sand drownded to the river bed because of the gravity. Low-velocity flow also cause by the tide of sea. It is why sedimentation is happen in estuary.In Juwana river case, using SMS 8.1 software with RMA2 model, on the highest tide, with the quantity of river-flow is 100 m3/s gained 0,15 m/s of the river velocity. Based on Hjulstorm diagram (Sundborg modification), with this velocity of river flow, will cause a sediment of anykind sand-particle.  Placing 6 of 45x45 square piles, 2 m between each pile on formation and placed every 50 m along side the river and when the river quantity is 100 m3/s at the highest tide, give a significant additional speed. It will rising the velocity up between 0,14 to 0,17 m/s.  In other word, the velocity of Juwana river becomes 0,29 m/s to 0,32 m/s, which is high enough to flush a fine-sand sediment.

Abstract

Salah satu permasalahan yang sering terjadi di berbagai sungai adalah permasalahan sedimentasi. Sedimentasi seringkali menjadi awal bagi permasalahan lainnya, seperti banjir, dan terhambatnya aliran sungai. Sedimentasi kerap diakibatkan oleh kecepatan aliran yang rendah. Kecepatan aliran yang rendah ini kemudian mengakibatkan terjadinya endapan yang berpotensi pada pendangkalan dasar sungai. Kawasan muara dari suatu sungai adalah yang paling rawan terhadap masalah ini. Letaknya yang berada berdekatan dengan garis pantai membuat aliran menjadi sangat lambat. Oleh karena itu pada muara yang kecepatan alirannya lambat, perlu dilakukan usaha untuk menaikkan kecepatan aliran.Dalam kasus Sungai Banjir Kanal Timur, melalui simulasi hidraulis dengan HEC-RAS 5.0.3. didapati kecepatan aliran pada saat pasang tertinggi dengan debit 79.0025 m3/detik adalah 0.18 m/detik, dengan diameter butiran d50 sebesar 0,0059 mm. Jika dievaluasi dengan grafik Hjulstrom maka kondisi tersebut akan jatuh pada fase transisi, dimana sedimen baru akan mulai bergerak.Penempatan krib corrugated concrete sheet piles W 350 sebanyak 8 buah di kedua sisi sungai dengan jarak 30 m antar sheet piles, sepanjang 1000 m dari muara, pada debit 79,0025 m3/detik, ternyata memberikan penambahan kecepatan sebesar 0,72 m/detik. Sehingga kecepatan pada muara Sungai BKT menjadi 0,8 m/detik. Jika dievaluasi dengan grafik Hjulstrom maka kondisi tersebut akan jatuh pada fase bergerak atau fase dimana sedimen sudah tertransportasi.
