  Abstract

 Analisis dampak lalulintas merupakan bagian dari analisis mengenai dampak lingkungan, Analisis ini diperlukan pada suatu rencana pembangunan suatu pusat kegiatan, yang diperkirakan akan memberikan dampak terhadap arus lalulintas di sekitarnya. Metoda yang digunakan adalah dengan memperkirakan dampak lalulintas jika dibangun pusat kegiatan tersebut, dan usaha yang dilakukan untuk mengatasinya. Penerapan metodologi ini diuraikan dengan studi kasus analisis dampak lalulintas pembangunan Plaza Ambarrukmo di Yogyakarta. Pertama-tama dilakukan survai lalulintas, geometri di sekitarnya, serta tata bangunan plaza tersebut. Hasil analisis memberikan rekomendasi tentang perbaikan-perbaikan lingkungan Plaza Ambarrukmo tersebut, termasuk ruas-ruas jalan di sekitarnya guna menghindari kemacetan yang mungkin terjadi akibat pembangunan plaza tersebut.

  Abstract

Today, about half of the world population lives in urban areas and in the coming 20 years, urbanization is expected to increase steadily, especially in the Developing World. Based on UN data and projections, about 4 out of the 5 billion world urban population will live in developing countries by 2030. Large cities in the Developing World face the problem of unplanned growth, coupled with the financial and operational inability to offer the public services needed to sustain a decent life in urban environments. Water is one of those essential commodities which is often short in supply and/or of low quality. Additionally, flood poses a threat to urban dwellers during rainy season. The water management challenges in tropical urban areas today and in the decades to come can be characterized by (1) fighting physical shortcomings in water resources, (2) coping with contamination of groundwater, rivers, lakes, and reservoirs by domestic, agricultural or industrial waste and waste water, (3) mitigating environmental impacts of water extraction (such as loss of wetlands, subsidence and seawater intrusion), (4) preventing / mastering flood situations and (5) overcoming administrative and financial strains and operational incapacities. Solutions to the problems of urban water in 20 years time are to be found in supply side and demand side measures. The first group includes (1) optimal use of surface water and groundwater resources, (2) pollution protection, (3) watershed management and (4) more water storage. The second group includes (1) educational training, (2) technological innovation, (3) water conservation and (4) water pricing.
