Air adalah materi vital bagi setiap makhluk hidup. Namun keberadaannya seringkali tidak disyukuri dan disia-siakan dan disalahgunakan. Pengelolaan air yang tidak pada tempatnya ini menyebabkan munculnya begitu banyak kerugian. Pelestariannya yang diabaikan menyebabkan permasalahan ketika jumlah air melimpah pada musim penghujan, namun tidak bisa dimanfaatkan. Ketika musim kemarau tiba, jumlahnya tidak seberapa, dan untuk mendapatkannya memerlukan pengorbanan lebih. Jakarta adalah salah satu kota di dunia yang mengalami permasalahan serupa. Volume air yang melimpah di musim penghujan menyebabkan banjir di mana-mana, menimbulkan kerugian yang tidak sedikit dalam berbagai aspek. Di musim kemarau, banyak anggota masyarakat yang kesulitan mendapatkan air untuk memenuhi kebutuhan sehari-hari.Kajian ini dibuat untuk mengidentifikasi permasalahan pengelolaan air Daerah Khusus Ibukota Jakarta dari sudut pandang konservasi Sumber Daya Air. Permasalahan penggunaan tanpa izin kawasan bantaran sungai dan perubahan tata guna lahan di berbagai bagian Daerah Aliran Sungai, terutama di bagian hulu menjadi masalah yang tidak bisa dibiarkan begitu saja. Peningkatan angkutan sedimen karena erosi lahan dan penurunan indeks kualitas air juga patut mendapatkan perhatian lebih.Kata kunci: Air, Konservasi, Jakarta
The rapid growth of Satellite City in South Tangerang will directly impact road infrastructure and environmental conditions. The purpose of this paper is to investigate the performance of existing road infrastructure. The study was to gain the perception of road users regarding various elements of satellite city self-reliance in maintaining the quality of road infrastructure for the Central Business District (CBD) area. Using one of Satellite City in South Tangerang as a case, the specific research objectives are to: ascertain road users level of satisfaction with the road infrastructure such as road features, road drainage system and environment; find out problems faced by road users when using the road infrastructure; determine the most dominant factors affecting road users satisfaction; and develop a road user satisfaction index (RUSI) to measure the road performances. A questionnaire survey was conducted on road users in three selected roads in Satellite City. Through a random sampling, a total of 384 responses were collected. Data processing using SPSS software version 20.00 through Cronbach Alpha (α) statistical method and Importance Performance Matrix Analysis (IPMA) has been applied to know the level of satisfaction and importance user. Overall, the user satisfaction index for three road segments in Satellite City is still at a good level with the overall score reaching 2.851 and has not yet reached a very satisfying level (score above 4.0).
