This study investigated the use of e-Procurement in selected construction firms in Oyo state, Nigeria. The data were derived using a well-structured questionnaire survey involving 104 respondents. Descriptive statistical and correlation analyses were used to analyze the data. Findings show that the use of electronic procurement in the selected construction firms for carrying out procurement function is high with majority of the professionals affirming the use of the system, the four categories of e-Procurement used were e-mail, static websites, web.2.0 technologies and portals that have capabilities of supporting the execution of functions limited to intra and inter firm communication and exchange of project information and data. Consequently, between 84 percent and 76 percent of the respondents used these e-Procurement technologies for communication of information, exchange of bill of quantities, project reports, CAD drawings and project specifications. Consequently, factors with the highest positive impacts on the use of these technologies in the firms were the speed of transactions, lower transaction cost and ease of use. The study implies that the selected construction firms in Oyo state Nigeria predominantly use e-mails and websites to support the execution of pre-award phase of construction procurement. Finding also shows that there is positive relationship between e-Procurement (e-Notifying, e-Exchange, and e-Submission of bid) and Project delivery. The study suggests that to accelerate the rate of uptake of e-Procurement and maximize its benefits in the Nigerian construction industry, there is a need to improve the quality and quantity of ICT infrastructure across the country; and to embark on aggressive enlightenment campaigns, training and skill development programs in the use of e-Procurement in the construction industry in this country.

The use of nanocrystal (NC) building blocks to create metamaterials is a powerful approach to access emergent materials. Given the immense library of materials choices, progress in this area for anisotropic NCs is limited by the lack of co-assembly design principles. Here, we use a rational design approach to guide the co-assembly of two such anisotropic systems. We modulate the removal of geometrical incompatibilities between NCs by tuning the ligand shell, taking advantage of the lock-and-key motifs between emergent shapes of the ligand coating to subvert phase separation. Using a combination of theory, simulation, and experiments, we use our strategy to achieve co-assembly of a binary system of cubes and triangular plates and a secondary system involving two two-dimensional (2D) nanoplates. This theory-guided approach to NC assembly has the potential to direct materials choices for targeted binary co-assembly.

Semiconductor Companies and Industries soar high as the trend for electronic gadgets and devices increases. Transition from “manual” to “fully automatic” application is one of the advantages why consumer adapt to changes and prefer electronic devices as one of daily answers. Individuals who admire these electronic devices often ask how they are made. As we look inside each device, we can notice interconnected microchips commonly called IC (Integrated Circuit). These are specially prepared silicon wafers where integrated circuit are developed. Commonly, each device is composed of numerous microchips depending on the design and functionality IC production is processed from “front-end” to “back-end” assembly. Front-end assembly includes wafer fabrication where electrical circuitry is prepared and integrated to every single silicon wafers. Back-end assembly covers processing the wafer by cutting into smaller individual and independent components called “dice”. Each dice will be placed into Leadframe, bonded with wires prior encapsulating with mold compounds. After molding, each IC will be cut through a process called singulation. Afterwards, all molded units are subjected for functional testing. Dice is central to each IC; it is where miniature transistor, resistor and capacitor are integrated to form complex small circuitry in microchips. Pre-assembly (Pre-assy) stations have the first hand prior to all succeeding stations. Live wafers are primary direct materials processed in these stations. Robust work instruction and parameter must be practiced during handling and processing to avoid gross rejection and possible work-related defects. The paper is all about the challenges to resolve and improved the backside chippings in 280um wafer thickness in mechanical dicing saw. The conventional Mechanical dicing process induce a lot of mechanical stress and vibration during the cutting process which oftentimes lead to backside chipping and die crack issues. However, backside chippings can mitigate with proper selection of parameter settings and understand the silicon wafer properties.

This study aims to analyze e-government service quality in the goods and services procurement in Riau Province, particularly in Pekanbaru City.  The data were collected through an in-depth interview analyzed using a dialogical interpretation approach. The results showed that the service quality of goods/services procurement in Riau Province coordinated by the Electronic Procurement Service (LPSE) through its website http://lpse.riau.go.id has already met the users’ expectation. Even so, the ad hoc position of the Work Unit of LPSE Riau, decreasing enthusiasm of goods/services providers for upgrading the skills of their human resources, and ineffective communication between LPSE, ULP and PDE of Riau Provincial Government effectively degrade the quality of service that has already run well. Hence, there should be a restructuring of LPSE and Work Units related to the e-government implementation in order to synchronize the implementation of e-government in general and e-procurement in particular in Riau Province.

Procurement System

In the last few years in the world of auctions, electronic auctions become a hot topic for discussion, especially in Indonesia. In Indonesia, the auction has been using online electronic system since 2007 with all its advantages and disadvantages. This system is one of a fairly successful program in a good governance. Until now, there are 620 government agencies in Indonesia have been using this electronic procurement systems[19]. The Government can perform a budget efficiency nearly 5% of the total budget by using today's electronic procurement system. The current system is good enough, but there are still some deficiencies found. Some of solutions to cover the deficiency offered in this paper. Starting from the classification of goods or services according to the UNSPSC, applying business classification with ISIC Indonesia in 2009, recording the activity of vendors for consideration decision, and implementing a decision support system using AHP to facilitate the auction committee to determine the winner. All of above matters are intended to improve the effectiveness and efficiency of the current system.
