Abstract

Air merupakan salah satu sumber daya alam yang memiliki fungsi sangat penting bagi kehidupan.Tujuan dari penelitian ini adalah mengkaji kondisi sumber daya air dan sistem penyediaan air bersih di Kabupaten Aceh Besar dan Kota Banda Aceh. Sumber daya air berupa sungai dan danau mengalami kerusakan pasca bencana tsunami. Salah satu parameter penting kualitas air adalah kondisi mikrobiologis. Hasil penelitian menunjukkan bahwa terdapat Coliform di semua titik pengambilan air sungai. Jumlah populasi bakteri Coliform yang paling tinggi terdapat pada Sungai Krueng Raya Muara sebanyak 3100 koloni/100mL. Bakteri fekal Coliform tertinggi terdapat pada Sungai Simpang Surabaya sebanyak 1600 koloni/ 100mL dan bakteri fekal Streptococcus tertinggi terdapat pada Sungai Krueng Raya I sebanyak 420 koloni/100mL. Pipa distribusi daerah Lampaseh tercemar oleh total Coliform sebanyak 140 koloni/100 mLdan fekal Streptococcus sebanyak 80 koloni/100 mL. Sumur dangkal daerah Lampaseh tercemar bakteri total Coliform sebanyak 850 koloni/100 mLdan fekal Streptococcus sebanyak 190 koloni/100 mL. Kondisi perairan sungai di Banda Aceh hampir seluruhnya perlu dilakukan pengolahan lebih lanjut untuk dapat digunakan sebagai sumber air baku untuk air bersih, termasuk pipa distribusi dan sumber air sumur daerah Lampaseh.

Abstract

The Kalijodo Green Open Space (GOS) which has a vegetated land area of 48%, does not meet the ideal criteria for a GOS, which should have a minimum vegetated land area of 80%. With this area, the water absorption capacity of the Kalijodo GOS is only 45% from what it should be 75%. The ability to absorb water can impact the potential income generated if the infiltration water in the Kalijodo GOS is managed properly. This study aims to determine the potential income generated if the management of infiltration water in the Kalijodo GOS is carried out by comparing the management of infiltration water in current conditions to the ideal conditions using comparative descriptive analysis methods. The results showed that the community served by the distribution of clean water from the infiltration water management process at the Kalijodo GOS in its current condition was 348 people (87 households). This number is less than the number of people served by the distribution of clean water from infiltration water management under ideal conditions, which is 580 people (145 households). The income generated from the management of infiltration water in the Kalijodo GOS in its current condition compared to the management of infiltration water in the ideal conditions shows a loss or shortfall of Rp45,518,400. Thus, the condition of the Kalijodo green space needs to be improved according to the ideal area of vegetated land to increase the ability to absorb water so that the number of people who get access to clean water and the income from the infiltration water management increase
