Abstract

Masalah yang paling sering muncul di daerah perkotaan akibat pesatnya pertumbuhan ekonomi dan pembangunan adalah masalah banjir.Tujuan penelitian ini adalah untuk menyiapkan pola dan rancangan penanggulangan banjir pada kawasan Bambu Kuning Kota Jayapura. Faktor penyebab banjir di lokasi studi, diantaranya adalah sistem drainase eksisting tidak mampu menampung debit limpasan permukaan, hal ini karena dimensi saluran drainase terlalu kecil yaitu lebar 0,3 m dan tinggi saluran 0,3 m dengan kapasitas tampungan sebesar 355m3, sedangkan volume banjir limpasan permukaan adalah 5.700 m3, selain itu tidak adanya outlet drainase dari kolam tampungan sehingga genangan meluap ke jalan raga serta adanya permukiman penduduk yang dibangun diatas kolam tampungan dengan cara menimbun kolam tampungan dengan tanah mengakibatkan kapasitas kolam tampungan berkurang dari volume 5.169 m3 menjadi 3.500 m3 Untuk itu diperlukan alternatif upaya penangan banjir di kawasan Bambu Kuning secara komprehensif meliputi normalisasi saluran dengan cara memperlebar dan memperdalam saluran eksisting, membuat saluran baru, membuat long storage channel kombinasi parafet dan gorong-gorong, dan melakukan pengerukan kolam tampungan.Kata kunci: Debit limpasan permukaan, penanggulangan banjir, normalisasi saluran, long storage channel.

Abstract

Abstrak: Muara Sungai Banjir Kanal Barat mempunyai morfologi melebar ke daerah hilirnya sehingga kecepatan aliran sungai kecil yang berpotensi menimbulkan sedimentasi di muara. Selain itu adanya pasang surut dari air laut yang mengakibatkan sedimen di muara tidak bisa terbawa arus sungai ke laut bahkan kembali ke muara sungai oleh adanya backwater. Berdasarkan perhitungan transpor sedimen sejajar pantai dengan menggunakan metode fluks energi diperoleh sedimen sejajar pantai sebesar 591.017,140 m3/thn, sedangkan untuk angkutan sedimen dari sungai menggunakan persamaan Engelund&Hansen sebesar 127.952,470 m3/th. Volume budget sedimen diperoleh sebesar 718.969,610 m3/th. Berdasarkan perbandingan prisma pasang surut dan angkutan sedimen total (budget sedimen) P/Mnetto didapatkan nilaiS = 6,320 berdasarkan nilai tersebut maka muara sungai Banjir Kanal Barat memiliki mulut sungai yang tidak stabil karena nilai S < 20 (Triatmodjo, 2012).Sistem penangan yang baik untuk mengatasi masalah sedimentasi di muara sungai Banjir Kanal Barat adalah  pengelolaan  mulut sungai yang selalu terbuka dengan membuat jetty panjang di kedua sisi muara dengan panjang 1080,45 meter di  sebelah kiri  dan 646,06 meter di sebelah kanan muara sungai.Kata Kunci : Muara sungai, Gelombang, Angkutan sedimen, Pantai, Jetty Abstract: The Western Flood Canal estuary has a widening morphology towards downstream areas, so that the velocity of small streams can create sedimentation in the estuary. In addition, there are also seawater tides that results in sediment in the river estuary not being carried to the sea, instead returning to the estuary due to the presence of backwater. Based on calculations of coastline sediment transport using the energy flux method, the coastline sediment transport is 591.017,140 m3/yr., while river sediment trasport is determined by the Engelund and Hansen equation to be 127952.470 m3/yr. The sediment budget volume is         718.969,610 m3/yr. Based on the comparison between prism tides and total sediment transport (sediment budget) P/Mnetto, a value of S = 6,320 was obtained. Based on these values, the Western Flood Canal estuary has an unstable river mouth because S < 20 (Triatmodjo, 2012). A good handling system to overcome the problem of sedimentation in the Western Flood Canal estuary is the management of an always-open river mouth by the creation of a long jetty on both sides of the estuary with a length of 1080,45 meters on the left and 646,06 meters on the right.Keywords: estuary of river, wave, sediment transport, shore, Jetty

Topografi yang ada pada Daerah Aliran Sungai (DAS) Lesti termasuk cukup terjal dengan kemiringan lereng sampai dengan 40%. Kondisi Daerah Aliran Sungai (DAS) Lesti yang sekarang ini menyebabkan pada Daerah Aliran Sungai (DAS) tersebut sering terjadi banjir dari tahun ke tahun. Pada jurnal ini upaya untuk mesimulasikan banjir yang ada pada Daerah Aliran Sungai (DAS) ini menggunakan pemodelan hidrologi fisik terdistribusi. Analisa sebaran curah hujan digunakan untuk mengevaluasi curah hujan serta debit pada Daerah Aliran Sungai (DAS). Memahami karakteristik Daerah Aliran Sungai (DAS) menjadi hal yang diperlukan untuk pemeliharan kondisi maupun penanggulangan bencana dimasa mendatang. Model fisik terdistribusi yang digunakan pada Jurnal ini ialah Block-wise use of TOPMODEL Muskingum-Cunge (BTOPMC). Aplikasi ini menggunakan analisa TOPMODEL untuk memperkirakan limpasan dan Muskingum-Cunge untuk penelusuran banjir aliran. Peta studi yang digunakan untuk pemodelan ini meliputi, Peta Tataguna Lahan, Peta Digital Elevation Map (DEM) dan Peta Tanah. Simulasi limpasan dilakukan pada 2 titik yaitu pada AWLR Tawangrejeni dan AWLR Bendungan Sengguruh. Hasil simulasi yang diterapkan menggunakan metode Nash-Sutcliffe Effiency dengan membandingan debit observasi dan debit simulasi. Pada simulasi yang sudah dilakukan model menunjukan efisiensi kalibrasi dan validasi berturut-turut sebesar 0,737 dan 0,604. Pemodelan ini sangat berguna untuk infomasi debit dan waktu serta memanajemen resiko bencana.

Abstract

Kebutuhan air yang meningkat sejalan dengan perkembangan jumlah penduduk dan meningkatnya kegiatan manusia maka dilakukan antisipasi terhadap ketersediaan air dengan melakukan analisis terhadap ketersediaan air waduk sutami. Ketersediaan air yang dipengaruhi oleh besarnya curah hujan dan evaporasi. Ketersediaan data pengukuran yang kurang memadai menjadi salah satu permasalahan. Permasalahan ini dapat diatasi dengan memanfaatkan data satelit. Namun, data satelit harus dilakukan uji kesesuaian data terlebih dahulu untuk mengetahui kecocokan antara data pengukuran dan data satelit. Metode uji kesesuaian data  yang digunakan yaitu, Root Mean Squared Error (RMSE), Nash Sutchliffe Efficiency (NSE), Koefisien Korelasi, dan Uji Kesalahan Relatif (KR). Uji kesesuaian data dilakukan dengan dua perhitungan, yaitu uji kesesuaian dara tidak terkoreksi dan uji kesesuaian data terkoreksi. Hasil analisis menunjukkan uji kesesuain data terkoreksi  memiliki nilai yang lebih baik dibandingkan dengan data tidak terkoreksi. Sedangkan untuk hasil analisis neraca air dengan menggunakan data pengukuran dan data satelit memiliki pola trend yang sama. Dan dapat disimpulkan bahwa data satelit yang digunakan dapat dijadikan sebagai alternatif data pengukuran. The increasing of water demand is coherent with population growth and also the increasing of human activities, so it is imoortant to give an anticipation of water availability by analyzing the Sutami Reservoir water. Water availability is affected by the amount of rainfall and evaporation. The availability of inadequate measurement data is one of the problems. This problem can be solved by utilizing satellite data. However, satellite data must be tested in advance in order to determine the compatibility between measurement data and satellite data. Data suitability test methods used including, Root Mean Squared Error (RMSE), Nash Sutchliffe Efficiency (NSE), Correlation Coefficient, and Relative Error Test (KR). The data suitability test is carried out with two calculations, the uncorrected data suitability test and the corrected data suitability test. The analysis shows that the corrected data suitability test has a better value compared to the uncorrected data. As for the results of water balance analysis using measurement data and satellite data have the same trend pattern. And it can be concluded that the satellite data used can be used as an alternative measurement data.
