Chronic Problem

The Logistics Performance Index (LPI) of Indonesia shows minor improvement compared to neighbouring countries such as Singapore and Malaysia. The economic disparity between Indonesia’s eastern and western regions has reportedly become one of the fundamental problems in the country. Consequently, an ambitious project on shipping connectivity improvement, namely the ‘Sea-Toll’, has been proclaimed by the Indonesian government to overcome this chronic problem. One of the most influential parameters for measuring the success rate of this project is cost efficiency. Therefore, this paper proposes a comparative approach by constructing a generalised cost model. It develops a measurement for transport costs that combines actual freight cost with the value of time attached to delivery activities concerning cargo types. Overall results study depend on the shipping network is described in terms of a current and future condition. This condition is because the factor of economies of scale has a significant influence in the combination of actual empirical data and extractions of regression approach with the function of vessel size. Finally, all scenarios show that there is a positive relationship with a convincing impact on efforts to save costs for domestic shipping routes after the implementation of the sea-Toll program.

To make biofuel production feasible from an economic point of view, several studies have investigated the main associated bottlenecks of the whole production process through approaches such as the “cradle to grave” approach or the Life Cycle Assessment (LCA) analysis, being the main constrains the feedstock collection and transport. Whilst several feedstocks are interesting because of their high sugar content, very few of them are available all year around and moreover do not require high transportation’ costs. This work aims to investigate if the “zero miles” concept could bring advantages to biofuel production by decreasing all the associated transport costs on a locally established production platform. In particular, a specific case study applied to the Technical University of Denmark (DTU) campus is used as example to investigate the advantages and feasibility of using the spent coffee grounds generated at the main cafeteria for the production of bioethanol on site, which can be subsequently used to (partially) cover the campus’ energy demands.

Construction industry has been proven to cause environmental problems ranging from excessive consumption of natural resources in construction, to the pollution of the environment. Studies on green building to minimize environmental impact are already underway. Tools of assessment of environmental performance of buildings are plenty. However, Middle East countries together with Gulf region are still away from practicing the concept of mitigating the impacts of buildings on the environment. Reasons could be relying on the insufficient awareness of building stakeholders, or the privilege of much fortune. The main objectives of this paper are to arouse the people's attention to the importance of assessment of environmental performance of buildings in KSA, and to introduce a sustainability model for project appraisal based on a multi-dimensional approach, that will be used for the assessment of a case study in KSA. The approach is using the LEED (Leadership in Energy and Environmental Design) rating system as a guide for the assessment. The plan of work includes reviewing the literature on the assessment of sustainability performance of buildings, displaying the LEED system, and assessment of a commercial building in Dammam. The paper uses the descriptive approach to study the problem and collect the data, and the comparative approach to compare the obtained data with the required standards of LEED. The case study, which is a commercial complex in Dammam, is one of these types of buildings widely spread in the development schemes of current real estate investment in KSA. While the building achieved some credits and prerequisites of LEED system, the building lacks many other points. The overall credits achieved are 22%, and the overall prerequisites achieved are 43%. The main problem of the building is related to energy and atmosphere aspects.

This study aimed at focusing on the role of universities in serving society and the surrounding environment during unstable (emergency) conditions, following the comparative approach with some models from western and Arab universities on one hand, and Libyan experience one the other hand, The approach of the case study is applying to Libyan universities during and after the February 17 revolution, This has a clear impact on all components of Libya society and universities, including the fact that, They are the most important and influential institutions in society in various settings at the international, regional and local levels. Also the study found that this role was generally weak, if any related to role was addressing the internal crises that universities are in between and lack of clear plans for universities Libyan universities in particular have been recommended to propose a strategy for activating the role of universities in community participation and contributing to the community participation and contributing to the community service of various institutions during unstable condition.

OpenStreetMap, a web mapping platform, is the most popular web map source for use in locationbased services with specific emphasis on pedestrian navigation, tourist guide applications, and other location-based search applications. This paper tests the positional accuracy of OpenStreetMap for the mapping applications using the case study in the campus of UMM El-Qura University, Makah, Saudi Arabia. The proposed testing method consists of statistical comparative approach using OpenStreetMap data and accurate land surveying reference data. The results show that OpenStreetMap data has positional accuracy of 1.57 m which is suitable for generating planimetric maps of scale 1:5000 or smaller. The obtained results open the door for using the OpenStreetMap maps for applications such as general preliminary planning where larger areas are covered but only moderate accuracy is needed. Applications include mapping the general layout of potential construction sites, proposed transportation systems, and existing facilities. The proposed methodology in this paper is of great interest to small engineering firms for the generation of local area maps from OpenStreetMap data.

Sustainable waste management, particularly in industrial areas, is one of the major challenges of developing countries. Among the important issues in the overall process of industrial wastes management is the necessity of suitable site selection for waste disposal. Considering the effects that the disposal sites exert on their surrounding ecosystem and environment, these sites should be located in places with the minimum destructive effects and the lowest environmental impacts. The aim of this research is to outline important criteria for industrial zone waste disposal site selection and to select optimal and proper disposal sites in the Salafchegan special economic zone. This region, as one of the most important industrial areas and closest to the country’s political–economic center, enjoys a privileged and unique position for producing, exporting, and transiting goods and products. There are various parameters involved in the optimal selection of suitable industrial waste disposal sites. In this case study, issues such as the depth of groundwater, distance from surface- and groundwater, access routes, residential areas, industries, power transmission lines, flood-proneness, faults, slope, and distance from gardens and agricultural lands were taken into account. Following selection and preparation of the maps related to the influential parameters, assigning weights was done through the Analytical Hierarchy Process (AHP) and using expert comments. At this stage, the maps and weights related to them were introduced into an index overlay model to obtain new maps from combining the influential parameters. Thereafter, the areas with the first and second priorities were selected and out of each one, four sites were suggested for disposing of industrial wastes. The sites with the first and second priorities were specified as A1, A2, A3, and A4 and B1, B2, B3, and B4, respectively. The area, groundwater depth, distance from residential areas, distance from the Salafchegan special economic zone, the direction of the predominant wind, and the land use of the selected sites were also investigated.

Historical Relationship

Do differences in port performance explain differences in maritime transport costs? How much would improvements in port performance reduce maritime transport costs in developing countries? To answer this question, we use a widely used transport cost model, but we provide a new measure of port efficiency, estimated through a non-parametric approach. Relying on data from the early 2000s, this paper shows that for a sample of 115 container ports in 39 developing countries, becoming as efficient as the country with the most efficient port sector would reduce average maritime transport costs by 5 percent. For the most inefficient country, the reduction in transport costs could reach 15 percent. These findings point out the potential gains that can be achieved from the combination of betterquality investment and more efficient service provision in the port sector. The estimates in this paper cannot be updated because the databases were discontinued and it therefore highlights the need to generate data to evaluate the effectiveness of public policies that are key to competitiveness.

We briefly review the topics that our case studies in Vanuatu, Marianas, the Philippines, Taiwan, China, Vietnam, and Japan highlight, and note the value of these studies in framing a comparative approach to colonialism in the Asia-Pacific region. Each case study highlights different aspects in the colonial relationship. The chapters have been grouped following a geographical criterion, and the imbalance reflects the fact that some areas have been better studied than others (e.g. for Marianas), albeit with different perspectives. We express our hope that the book has gathered some previously little systematic or accessible evidence, offered comprehensive histories of some of the areas, and raised questions for the future.

The aim of the chapter is to propose a methodology to illustrate the cost and time components of door-to-door movement by One Belt and One Road (OBOR) and traditional routes alongside with modes. The study is concentrated on a case study and uses established multimodal transport cost model as a research framework. Interviews with industry practitioners and observation from primary methods of data collection. The use of multimodal transport cost model is common in the containerized cargoes. Hence, this study provides an original analysis for OBOR initiative. The volumes of OBOR shipments are large, with a high value-to-volume ratio. The research initially confirms that multimodal transport alternatives and modal combinations may successfully be applied and assess the performance of OBOR initiative.
