Abstract

This study offered ways to improve the efficiency and adequacy of urban public transport in Kupang, taking as the background the viewpoint that urban transport should concern not only middle and high income people but urban poor as well. It focused on three principle modes of public transport in the city, two of which are formal: city bus, and bemo, and the remaining one is informal/paratransit locally known as ‘ojek’. It took urban transport strategic review published recently by the World Bank as the quarry form which solutions for efficiency and adequacy the city’s passenger-transport were drawn and developed as to suit specific demand of the same. It concluded that to improve the service of public transport in the city, ‘competition-for the-market’ should be introduced into the market of its urban transport form of for-the-market competition recommended are route-concession. It stressed also however that prior to it state-owned motor companies should be privatized, and their capacity to engage in an open competition should be made better. As for bemo, service-contract should be introduced into the relation between the owner and the operators, whereas paratransit should be recognized and regarded as part of the whole urban public transportation system

Abstract

The rain that falls on the surface of the earth is influenced by several factors that are not evenly spread to a region of the river. It can be determined by the proper placement of rain station, good location, number and pattern of spread. However, the placement of the rain stations are generally based only on immediate needs, so do not pay attention to the development of water resources as a whole. This research is specifically done on Aesesa with area of 8.202,41 km2. Methods to be used in this study is the method of Kagan. Analysis of the WS Aesesa obtained daily rainfall correlation coefficient 0,184 and 0,293 monthly. Existing density of rainfall stations in the WS Aesesa 1.025,0 km2 /Station. For daily rainfall, averaging 5% error obtained an area 195,295 km2/stations and 42 stations, alignment errors of 10% obtained an area of 585.886 km2/stations and 14 stations. While 5% for monthly rainfall, obtained an area of 182,276 km2/ stations and 45 stations, 10% error obtained an area 546,827 km2/stations and 15 stations. The number of stations is not the only factor affecting the level of rainfall forecast accuracy, but the pattern of spread also plays a role in determining the level of accuracy.
