Abstract. Land use change are become issues for many river basin in the world, including Cikapundung River Basin in West Java. Cikapundung River is one of the main water sources of Bandung City water supply system. In the other hand, as one of the tributaries of Citarum River, Cikapundung also contributes to flooding in the Southern part of Bandung. Therefore, it is important to analyze the effect of land use change on Cikapundung river discharge, to maintain the reliability of water supply system and to minimize flooding in Bandung Basin. Land use map of Cikapundung River in 2009 shows that residential area (49.7%) and mixed farming (42.6%), are the most dominant land use type, while dry agriculture (19.4%) and forest (21.8%) cover the rest. The effect of land use change in Cikapundung River Basin is simulated by using Hydrological Simulation Program FORTRAN (HSPF) through 3 land use change scenarios: extreme, optimum, and existing. By using the calibrated parameters, simulation of the extreme land use change scenario with the decrease of forest area by 77.7% and increase of developed area by 57.0% from the existing condition resulted in increase of Qmax/Qmin ratio from 5.24 to 6.10. Meanwhile, simulation of the optimum land use change scenario with the expansion of forest area by 75.26% from the existing condition resulted in decrease of Qmax/Qmin ratio from 5.24 to 4.14. Although Qmax/Qmin ratio of Cikapundung is still relatively small, but the simulation shows the important of water resources analysis in providing river health indicator, as input for land use planning.

“…Provinsi Jawa Barat merupakan salah satu Provinsi dengan jumlah kejadian banjir yang tinggi, yaitu sebesar 863 jumlah kejadian banjir, dan jumlah kejadian banjir terbesar berada di Kabupaten Bandung yang tercatat 228 kejadian. Kejadian banjir yang tinggi di Kabupaten Bandung dipengaruhi oleh kondisi morfologi lahan berupa cekungan, dan faktor antropogenik diantaranya perubahan penggunaan lahan hutan menjadi lahan pertanian (Dasanto et al, 2014). Berdasarkan kondisi morfologinya wilayah tersebut disebut sebagai Cekungan Bandung.…”

“…Beberapa peneliti telah memperlihatkan perkembangan dalam teknik pendeteksian daerah bahaya banjir, diantaranya Grimaldi et al (2013), Dasanto et al (2014), Shrestha dan Lohpaisankrit (2016), Kourgialas dan Karatzas (2017). Grimaldi et al (2013) Penelitian tersebut mampu menggambarkan hidrodinamika genangan, yang memungkinkan pemetaan kedalaman aliran dan luasnya pada skala yang detail.…”

Penilaian Bahaya Dan Arahan Mitigasi Banjir Di Cekungan Bandung

Banjir di Cekungan Bandung terjadi setiap tahun di wilayah cekungan terendah seperti di Kecamatan Majalaya, Ciparay, Deyeuhkolot, Rancaekek, Bojongsoang, dan Baleendah, Kab. Bandung. Kajian analisis bahaya dan arahan mitigasi banjir merupakan salah satu upaya untuk mengurangi risiko dari bencana tersebut. Tulisan ini bertujuan untuk menganalisis bahaya dan menyusun arahan mitigasi banjir di wilayah Cekungan Bandung. Bahaya banjir diidentifikasi dengan menganalisis daerah bahaya banjir menggunakan Modification Topography Wetness Index (MTWI), sedangkan arahan mitigasi banjir dianalisis secara deskriptif dengan membandingkan hasil analisis bahaya dengan data penggunaan lahan. Hasil penelitian menunjukkan bahwa 2.36% daerah Cekungan Bandung termasuk kelas bahaya tinggi, 7.15% termasuk bahaya sedang, dan 90.49% termasuk daerah bahaya rendah. Kesadaran masyarakat terhadap pengelolaan lingkungan yang rendah juga menjadi salah satu faktor penyebab banjir di Cekungan Bandung. Pada zona prioritas arahan mitigasi banjir dilakukan dengan pembuatan saluran drainase tambahan untuk mengalirkan air dari cekungan terendah. Selain itu, perlu dilakukan pengendalian penggunaan lahan dengan cara penegakan hukum terhadap penggunaan lahan yang tidak sesuai Rencana Tata Ruang Wilayah (RTRW) dan dilakukan rehabilitasi hutan dan lahan pada lahan kritis di DAS Citarum Hulu.

Land use change is a dynamic process of human activity and these changes will affect hydrological response of a watershed. The research aimed to identify hydrological responses of Asahan watershed due to land use change. Post classification image analysis method was applied to analyze landsat image to detect land use change. SWAT model was built using land use data, soil type and daily climate data from 1985-2010. The results showed that landuse change were more prevalent in non forest land while the forest was relatively fixed. Optimum land use was shown in 2010, indicated with the lowest surface run off and the highest water yield. Improved hydrological response of Asahan Watershed throughout 1985-2010 occured due to relatively fixed area of forest cover, reduction of barrend land and shrubs and addition of plantation area.
