Abstract

A house is an essential facility that affords an abode, provides habitation and shelter adequacies. Affordable housing presumes access to a conducive, functional, and sustainable dwelling by the majority of the people within a locality. The study investigated the factors mitigating the actualization of affordable housing for low-income masses in the selected area. Survey research was adopted for the study. The population for the study is made up of two groups comprising low-income masses and construction professionals. The study adopted a multi-sampling method. Both convenient and random sampling techniques were utilized to gather information from the respondents. Statistical Package for Social Sciences (SPSS) was used for descriptive (frequency, percent, and mean score) and appropriate inferential analysis. Results indicated factors weighing down the provision of affordable housing as well as factors precluding accessible housing for low-income masses. Also, the response from construction professionals showed the level of agreement on factors impeding the provision of affordable housing. The trail to alleviate the effect of the non-affordability of housing for low-income masses becomes perceptible and addressed.

Abstract

With the suboptimal performance of the Jakarta-Surabaya corridor railway currently operating, the Government of Indonesia intends to upgrade the railway system in terms of speed performance as well as to engage the participation of both the public and private sectors in the upgrading project as mandated in Presidential Regulation Number 38/2015. Through this research, the type selection of the Public-Private Partnership (PPP) scheme and their implications on the Jakarta-Surabaya railway project will be demonstrated by conducting analysis to the alternative scenarios of the study on railway technology selection with an emphasis on economic and financial feasibility aspects to determine the suitable PPP type,  which is validated through Value for Money (VfM) analysis,  where the benefits of the selected PPP type in terms of economic, financial, and non-financial aspects were examined through numerical tests, the result of which indicated that with the VfM value of the actual data of IDR 224.51 trillion, and the most significant changes in VfM value for each variable change are in the 20-year concession period which reduces the VfM value by 4%. Of all the variable changes, there is no minus VfM value, indicating that public projects are in an improved condition with the PPP scheme.

Abstract

The use of substandard materials for the construction of residential buildings within Lagos metropolis is experiencing a growing concern for both the government and the residents. The construction of half-lived and substandard buildings contributes to negative consequences ranging from rapid deterioration of building elements, premature failures of key building components, and sometimes building collapse. This study attempts to investigate the factors influencing the use of substandard construction materials for the construction of residential buildings in Lagos State. This research collected primary data through a cross-sectional survey of professionals engaged in the construction of buildings and building owners within the study area. Two sets of structured questionnaires were developed and administered to each of the groups of respondents, respectively. The collected data were analysed using descriptive and inferential statistical tools. The results show that factors influencing the use of substandard construction materials for the construction of residential buildings include corruption, use of quacks, contractor’s greed and selfish interests, and client’s financial constraints. The results suggested no significant difference in the perception of contractors and building owners on the factors influencing the use of substandard materials for the construction of residential buildings. The study concludes that the use of substandard building materials for the construction of buildings could cause structural failure, high maintenance costs, incessant building defects, and accelerate deterioration of building elements and components. Building clients suggest to engage professionals and refrain from patronizing quacks.

Abstract

Studies on the microstructural characteristics of the interfaces in reinforced concrete and its effect on the mechanical properties i.e. bond strength have been conducted for many years, even since 1956. However, a summary of existing knowledge and findings related to the different types of interfaces is still lacking. Therefore, this paper reviews the characteristic of different types of interfaces in reinforced concrete including those between: a) aggregate particles and cement paste, i.e. the interfacial transition zone (ITZ); b) steel reinforcing bars and concrete; and c) old (substrate) and new concrete (repair materials). The aim of this review is to show how similar and different the characteristics of interfaces in reinforced concrete. Such information is important for understanding the properties and durability as well as how it might affect the long-term performance of concrete structures.

Abstract

The quest for sustainable development has placed universities in the central role of sustainability in teaching, research, and application of sustainable principles in the development of their assets. To this end, there was the development of sustainable designs and structures out of many shipping containers within the University environment based in Yola-Nigeria. This study evaluated the satisfaction and comfort of users of the administrative office building through post-occupancy evaluation. The Building Use Studies (BUS) method was adopted to evaluate the performance of the buildings. Data obtained were analysed using the descriptive method of analysis of the BUS survey. Findings show that some sustainable features necessary to ensure the performance of the building, provide comfort and enhance workers’ productivity are entrenched in the buildings. All the requisite variables necessary to ensure satisfaction and comfort of the occupants/users of the Buildings are within or above the established benchmark. The lack of personal control of some key variables such as thermal comfort in the physical surrounding is noted to affect some users.

Abstract

The rapid growth of the industry is giving positive effects for humans by providing daily needs and supporting economic development. However, the industrial process also releases pollution to the environment, which can cause water scarcity, biodiversity loss, and climate change. Removing these pollutants from various industrial wastes is a requirement for ensuring proper water quality for human consumption, agricultural use, and environmental safety. This work aims to explain the use of natural resources as a source of valuable compounds that can be used in wastewater treatment, particularly in Indonesia, by adopting a literature study method reviewing both national and international references. Chitosan is an effective bio-absorbent pollutant because of its high level of deacetylation and free amino groups, making it polycationic which is capable of being bound to metals, proteins, and dyes. Chitosan membranes can be applied only with chitosan material and composites: chitosan-Polyethylene Glycol (PEG), chitosan-Poly Vinyl Alcohol, chitosan-biosilica, chitosan-PVA-silica, chitosan-alginate, chitosan-cellulose, and chitosan-silica. Chitosan has the ability as a coagulant and reducing water turbidity. Chitosan can absorb metal ion (Cr (VI), Cs+, Pb(II), Fe, Cu(II)), dyes (anthraquinone dyes, brilliant blue, yellow dye, methylene blue, disperse orange, disperse blue, rhodamine B), drug residue, and hazardous materials, and can be used as raw material or in a film form. Since there is a high abundance of chitosan raw material in Indonesia, it is supposed to be able to support the application of chitosan as a natural purifying agent considering its high ability to absorb heavy metal and some dangerous materials.

Abstract

Indonesian Police attempt to reduce the fatality rate of traffic accidents by enforcing the law on speed restrictions using speed cameras. The National Police Traffic Corps (Korlantas), from 2017 to 2018, had installed 75 units of speed cameras along Jakarta Toll Roads including Cikampek, Jagorawi, Bitung, and many others. By the end of 2020, Korlantas is expected to install 75 more units on the arterial roads of Jakarta. This study aims to analyze the implementation of vehicle speed deceleration through signs and speed cameras in the control zone. The data analyzed by comparing the speed of vehicles when crossing the control zone using the normal distribution Z test, with a 5% margin of error. The research shows that speed deceleration policy using signs and speed cameras in the control zone reduces the speed by 9% or equal to an average speed of 8 km/hour. Drivers who obeyed the speed limit reach 76.6% or 230 vehicles from 302 vehicle samples, where most of them are buses, followed by passenger cars and freight cars, respectively. The application of speed deceleration using signs and speed cameras in the toll toad meets the planning target and is recommended to be implemented across the country.

Abstract

This study is about the port planning under deep uncertainty using the framework of Scenario Based-Adaptive Port Planning (SB-APP). The framework gives sequential workflow on designing the future masterplan of the port. The alternative layouts and adaptive actions are some important outcomes of the framework. The port has to realize that uncertainties persevere and are very likely to influence the decision making for future planning. Instead of ignoring uncertainties, the port needs to make contingency planning to deal with them. This study has benefits to make a robust terminal masterplan of the port.
