Abstract

Fuel oil is the main fuel in the transportation sector. Transportation system and the city typology influence the fuel consumption of a city. This study aims to analyze and to compare the relationship of transportation system and the typology of the City of Semarang and the city of Surakarta to the fuel consumption of those cities. An analysis was performed using bivariate and multivariate-multivariable regression techniques. Uneven distribution of the population, public transport services dominated by passenger cars, and radial road network result in inefficient fuel consumption in the city of Semarang (0.27 kl/person). Meanwhile an even distribution of the population, public transport services dominated by public bus, and grid road network make fuel consumption more efficient in the city of Surakarta (0.18 kl/person). The use of large-capacity public transport and compact land use can make more efficient use of fuel.

Abstract

One of challenges of sustainable transportation is a mobile activity that protects thesoure of urban resource conserving mobility. Gradient analysis is one of the methods to comparetrend pattern from several locations by observing the level of line declivity which is bridging twovariables. In the research, gradient analysis is used to observe linear relation between variable ofpeople density and premium necessity. Gradient line declivity of linear relation variable of peopledensity and premium necessity. Gradient line declivity of linear relation between of people densityand fuel consumption has a relatively-the- same pattern, that is, low declivity in middle town andhigh declivity in metropolitan cities. Middle town with less number of people (30% of all town peopleresearched) and low density, so fuel necessity increases a bit. Meanwhile metropolitan cities withlarge number of people (70%) and the high density will increase fuel consumption of towns aroundJava every year. Salah satu butir tantangan dalam transportasi berkelanjutan (sustainable transportation),adalah kegiatan mobilitas yang melindungi sumber/urban resource conserving mobilit.

Abstract

Apart from supporting to human life which is a part of positive impacts, transporation also contains negative impacts which does not only lead to local geographic scale of mainland, but also to the largesr one, including water and air environment, even atmosphere. When the negative impact comes to larger scale, macro decisions such policies supported by political issues should be intervented to minimize negative impacts and to develop a better transportation or a sustainable transportation in the future. It is an irony that most of professionals, technocrats, and scientiests related transportation in developing countries are still interested and focused in local issues of transportation phenomenon, model development for transportation planning and technical issues related to operational management analysis. Only a small group of them are interested in transportation impact studies for both local and larger area. It will be a rational justification to construct models to support decision making process in order to have a policy within line with sustainable environment which is not only useful for both local scale, but also larger scale (national and the earth).

Abstract

Delay in the implementation of the project often occurs due to various risk factors that have not been identified during project implementation, so that the impact on project delays and unexpected costs increases. However, each construction project has different risks, becaused the environmental conditions of the project, so that it requires handling different methods of project implementation. This study aims to: 1) analyze the risks that could potentially occur during the construction of the log dock extension; 2) Appropriate Handling Methods for the Implementation of the Log Dock Extension Work. The research method is done by identifying the risks that occur in the field and with the interview method about the possibility of possible risks that occur. The results of the study indicate five high-risk categories according to the perception of service providers that most influence on project delays. These risks include unpredictable external phenomena, such as tidal elevations that exceed plan, resulting in changes in design and method of implementation. The conclusions of this study include that the application of risk management to the implementation of the log dock extension project at the port of Tanjung Emas Semarang needs to be applied to minimize delays and reduce unexpected costs.

Abstract

A traffic accident is a tragedy or accident that occurs on the road involving a motorized or heavy vehicle with other road users or without a vehicle. This incident caused the victim to suffer physical, health and material losses. Traffic accidents occur due to several factors such as human error or inadequate road conditions. Even traffic jams can also lead to traffic accidents. The problem of driving and road safety needs to be considered to reduce the number of traffic accidents that occur. This study was conducted to determine the factors that cause accidents, especially those caused by road conditions and traffic performance. The method used in the field observation research and using data on the number of accidents in 2018–2020 located on Jalan Raya Ngaliyan which was taken from the accident data of the West Semarang Police Traffic Unit.
