Abstract

Kota Banda Aceh memiliki jumlah penduduk besar dan pertambahan penduduk yang tinggi dan terus meningkat akan memberikan implikasi pada tingginya tekanan terhadap pemanfaatan ruang kota. Beberapa tahun terakhir, kualitas ruang terbuka hijau (RTH) Kota Banda Aceh mengalami penurunan akibat menurunnya kualitas lingkungan perkotaan seperti terjadi banjir, tingginya polusi udara, menurunnya keserasian lingkungan perkotaan serta terbatasnya ruang yang tersedia untuk interaksi sosial. Penelitian ini bertujuan untuk mengetahui luasan RTH Kota Banda Aceh; membuat aplikasi program basisdata RTH serta menyediakan informasi persebaran RTH Kota Banda Aceh. Proporsi Kota Banda Aceh yang harus dijadikan kawasan RTH minimal seluas 1.799,37 ha. Total RTH Kota Banda Aceh eksisting yang tersedia 2.136,79 ha (35,63%) dari luas kota. RTH publik eksisting yang tersedia 651,53 ha dari luas wilayah sehingga mengalami kekurangan 548,05 ha. RTH privat yang tersedia 1.485,26 ha sehingga kondisi RTH privat memenuhi standar kecukupan yang ditetapkan. Aplikasi program berjalan dan terkoneksi dengan baik sehingga dapat memberikan informasi Ruang Terbuka Hijau di Kota Banda Aceh kepada pengguna informasi.Kata kunci: Basisdata, Kota Banda Aceh, Ruang Terbuka Hijau (RTH), Sistem Informasi Geografis, Visual Basic.Net 2008

Abstract

Soil and Water Assessment Tool (SWAT) model was used to simulate impact of landuse and climate change on water resources in Krueng Jreu subwatershed located in Aceh Province – Indonesia. The subwatershed is a primary source of water to irrigated 233.52 km2 paddy field area through a surface irrigation system. The model performance was considerably good in predicting streamflow. The coefficients of determination varied between 0.58 and 0.72, while the Nash-Sutcliffe coefficients (ENS) ranged between 0.65-0.72 and the percentage bias were in the range of -0.36 to 2.30. Scenarios were applied to the best fit model to evaluate watershed responses to land use and climate changes. The model predicted increases in both runoff and water yield by 1% and 0.1% respectively as the result of increasing 15% settlement area. When all agricultural land within subwatershed converted to forest, water yield would increase by 1% during dry period and runoff contribution would decrease by 5%. Increases in surface flow by 23.6% and water yield by 15.1% were found under scenario of increasing 10% of daily precipitation. Increasing in evapotranspiration caused by an increase of 1.5⁰C in daily air temperature would decrease surface flow and water yield by 0.8% and 1.3%, respectively. Combination scenarios of changes in daily temperature and precipitation would increase evapotranspiration rate, annual water yield and runoff contribution.
