Abstract

Travel routing is vital for efficient delivery of public and private services and the movement of people and goods. In Ghana, the major nature of travel routing is through the ‘trotro’ system. The trotro system uses an automobile to move people and goods along a prescribed travel route, with locally known stops where people get on and off the vehicle. The trotro system is significant because Ghanas road network and street addressing are imperfectly mapped. Thus, this paper critically evaluates the research challenges and opportunities for the development of an integrated trotro geographic addressing system. The widespread trotro address assignment and the availability of geolocation technology on mobile phones, make the integrated trotro geographic addressing framework an inexpensive and a comprehensive approach. The key research questions that need investigation for the development of such an integrated geographic addressing system are identified, together with a critical review of the problem, and its research challenges and prospects.

Abstract

Indonesia is a country that vulnerable to land and forest fires danger. This is not out of the presence of peatland in Indonesia is quite wide, which are mostly located in Sumatara and Kalimantan. The nature of peatlands are capable to store water in large quantities, but the surface dries quickly and become flammable during the dry season. This research aims to perform mapping areas that vulnerable to land and forest fires danger based on the physical parameters. Based on the results obtained can be used as the basis for develop land and forest fires early warning system in Indonesia. This research use GIS (Geographic Information System) for processing mapping of physical parameters which consists of Land Use Map, Topography Map and Soil Map in Sumatra and Kalimantan to get the forest and land fires danger map. The results of the mapping areas that vulnerable to forest and land fire based on the physical parameters resulting from this study have uniform patterns with the distribution and density of hotspots in the Sumatra and Kalimantan over the last 10 years (2006-2015). This is reinforced by the result of mapping accuracy test, where the percentage number of hotspots during the last 10 years both in Sumatera and Kalimantan area which is exactly vulnerable up to very vulnerable to land and forest fires danger by 74%.

Abstract

Sea level is one of ocean properties that needed to be observed. Sea level observation will give information about osean tides and tides datum. As technology became more reliable, people can develop new instrument easily. Recently, open source microcontroller “Arduino” became popular and lot of people using it to develop what we call “low-cost” instrument. But, there are several disadvantages if we build instrument directly. Simulation phase must be done before manufacture instrument. This phase will help to decrease cost and time. In this paper, we will describe the concept, algorithm, and simulation phase in manufacturing Low Cost Ocean Tides Monitoring Instrument.

Abstract

Transit Oriented Development (TOD) is believed to be able to overcome the issues of urban transport. However, in practice, the current TOD in Jakarta  Metropolitan Region (JMR) is still a deficiency in accommodating the needs of transportation movement and not in facilitating services in terms of TOD function. The objective of this paper was to re-assess the service quality of actual TOD in 54 commuter railway stations. The paper performed criteria-indicators and measured a composite TOD index by using Analytical Hierarchy Process (AHP)-multicriteria model, statistics test, and Geographical Information System (GIS) application. TOD index was found that urban areas have a high TOD index. On the other hand, the suburban areas have a low TOD-index. The statistical test showed that there was a strong correlation between different criteria. This paper concluded that most of the stations which were located in the suburban area had a low index thus need improvement. Consequently, the station areas needed to have a policy relevance.
