Abstract

ABSTRAKKota Bandung adalah ibukota Provinsi Jawa Barat dan mempunyai jumlah penduduk yang sangat besar, hal ini  mengakibatkan kurangnya ruang terbuka hijau karena pengalihfungsian tata guna lahan menjadi permukiman, kantor, industri dan lain-lain. Hal tersebut akhirnya mengakibatkan limpasan air permukaan berlebih pada saat musim hujan dan berkurangnya cadangan air tanah pada saat musim kemarau. Pada saat ini Kota Bandung masih menerapkan sistem drainase konvensional, sehingga potensi banjir menjadi tinggi karena dimensi saluran drainase yang kecil. Mengacu pada metode sistem drainase berkelanjutan yang telah diterapkan di negara-negara maju, diharapkan Kota Bandung dapat mengelola air hujan dengan baik dan terhindar dari bencana banjir. Pada penelitian ini dipilih beberapa metode yang cocok bagi kondisi Kota Bandung saat ini, metode tersebut adalah rain garden, infiltration strips, water roofs, rainwater tanks, cistern, swales, kolam detensi, infiltration trenches, eco- corridor dan kolam retensi. Metode-metode tersebut dipilih berdasarkan berbagai aspek seperti fungsi, kriteria teknis, kemudahan pembuatan dan kemudahan pemeliharaan.Kata kunci: Sistem Drainase Berkelanjutan, Bandung, limpasan air ABSTRACTBandung is the capital of West Java Province with a large population. This condition impacted to the decreasing of open green spaces due to conversion of land use into residential, offices, industrials and others. Consequently surface water run off increases during the rainy season and groundwater reserves decreases during the dry season. At this time Bandung still apply the conventional drainage system, so the potential for flooding is high because the dimension of the drainage channel is too small. Based on the method of sustainable drainage systems that has been applied in developed countries, Bandung is expected to manage rain water and prevent flood. This study is using a few suitable methods for Bandung’s current condition. The methods are rain garden, infiltration strips, water roofs, rainwater tanks, cistern, swales, detention pond, infiltration trenches, eco-corridor and retention pond. These methods are selected based on various aspects such as functionality, technical criteria, ease of construction and maintenance.Keywords: Sustainable Drainage System, Bandung, Run Off

Abstract

ABSTRAK Ruang terbuka hijau di Kota Bandung terus berkurang yang disebabkan oleh pertumbuhan populasi dan penggunaan lahan yang tidak sesuai dengan perutukannya sehingga mengakibatkan banjir. Maka diperlukan metode enanganan banjir dengan metode penanganan air permukaan dengan sistem drainase berkelanjutan. Prinsip dari metode ini adalah mengendalikan air permukaan yang dapat digunakan sebagai sumber air baku. Selain masalah tersebut, penyebab terjadinya banjir terletak pada masalah sosial dan kelembagaan. Pengelolaan drainase di Kota Bandung belum efektif sehingga masalah banjir tidak tertangani dengan baik. Penelitian ini mempelajari model- model pengelolaan sistem drainase di beberapa negara maju seperti Inggris, Singapura dan Belanda. Dengan berpedoman pada sistem kelembagaan pemerintah di negara-negara tersebut, diharapkan Kota Bandung dapat mengelola sistem drainasenya dengan baik dan berkelanjutan. Pada penelitian ini diusulkan model baru agar sistem pengelolaan drainase di Kota Bandung dapat terorganisir lebih baik dan efektif.Kata Kunci: sistem drainase berkelanjutan, kelembagaan, banjir. ABSTRACTThe green open space in Bandung is decreasing due to rapid population growth and improper land use which lead to flooding. Therefore an appropriate method to control floods such as sustainable urban drainage system is needed. The principle of the method is to control excess surface water that can be used as raw water. In addition to the problem, floods occur because of social and institutional problems. Until now, the institutional drainage system management in Bandung is not performing well. This research studies various sustainable drainage system institutional management models from several developed countries such as United Kingdom, Singapore and Netherland as references. A new model is proposed in order to improve the institutional arrangement for drainage system management in Bandung.Keywords: sustainable drainage system, institutional management, flooding

Abstract

ABSTRAKPenelitian ini bertujuan untuk mengetahui nilai infiltrasi tanah di kawasan kampus Universitas Muhammadiyah Yogyakarta (UMY) dalam rangka untuk menerapkan sistem drainase berkelanjutan. Pengukuran nilai infiltrasi dilakukan secara langsung di lapangan dengan menggunakan alat double ring infiltrometer pada 6 Lokasi yang terdiri dari 2 jenis penutup lahan (tanah dan rumput). Pada peneilitian ini juga dilakukan pengukuran nilai permeabilitas, kepadatan tanah lapangan dan kadar air tanah sebagai pendukung hasil pengukuran nilai infiltrasi yang didapatkan.Berdasarkan hasil pengujian permeabilitas pada lahan di kawasan kampus UMY, diperoleh data bahwa koefisien permeablitas rata-rata berkisar antara 4,31*10-3 -4,37*10-3 cm/s. Hal ini menunjukkan bahwa golongan tanah dari kedua jenis penutup lahan di atas adalah kerikil halus/pasir (medium permeability) dan cukup baik digunakan sebagai media resapan air limpasan untuk pengaplikasian model sistem drainase berkelanjutan. Hasil nilai pengujian kapasitas infiltrasi diperoleh 1,36-2,21 cm/jam untuk jenis penutup tanah dan 0,84-1,88 cm/jam untuk jenis penutup tanaman rumput.Kata kunci: kapasitas infiltrasi, koefisien permeabilitas (), kepadatan tanah lapangan, sistem drainase berkelanjutan ABSTRACTThis study aims to examine the value of infiltration rate in the yard area of Yogyakarta Muhammadiyah University (UMY) campus in order to promote the implementationof sustainable drainage system. Field infiltration rate wasmeasured directly at 6 locations usinga double ring infiltrometer,for two types of land covers (bare soil and grass). In addition, the permeability value, insitu soil compactness and soil water content were also measured tosupport the infiltration test results.The test results obtained for the yard area of UMY campus show that the average permeability range from 4.31*10-3 cm/s to 4.37*10-3 cm/s. This shows that the soil class for the two types of soil coverstested isfine gravel /sand (medium permeability) which meansthat the soil type is good to be used as a infiltration mediafor reducing the surface runoff. The infiltration rate from the tests are 1.36 to 2.21 cm/hr for bare soil and 0.84 to 1.88 cm/hr for grass cover.Key words: infiltration rate, permeability, soil compactness, sustainable drainage system

Abstract

The Winongo River originates in the Opak River and has many potential hazards such as flooding, cold lava floods and riverbank landslides, so a disaster risk analysis is necessary. The research area is located in the headwaters of the river which passes through the villages of Sendangadi, Sinduadi, Trihango, Bener, Tegalrejo and Pakuncen. The method used is semi-quantitative and qualitative, using tabular data and numerical assessment of land use, population and river hydrology. With the AHP (Analytical Hierarchy Process) method which determines the best choice from several supporting data. The method of determining disaster risk by weighting follows the Regulation of the Director General of BNPB Year 2012. A disaster risk assessment using the AHP method obtained a score of 1.1 in Sendangadi Village, 1.6 in Sinduadi Village. Trihanggo has a value of 1.1, Bener has a value of 1.3, Tegalrejo has a value of 1.4, and Pakuncen has a value of 1.5. Sendangadi and Trihango villages have the lowest risk level with the same value of 1.1. From the results of the disaster risk analysis it has been found that in all sub-districts that are flowed by the upstream Winongo River, they have a low level of risk.
