Modelling of Palm Oil Production Using Fuzzy Expert System
Research Output | Dar Al-hikmah Library | IIUM Only

The production of crude palm oil and palm kernel is a complex problem due to the influence of processing variables and environmental factors. These processing variables influence the amount of crude palm oil and palm kernel losses during processing. Instead of mathematical model, fuzzy logic approach provides a simpler and easier mechanism to descr

Nanosized Tio2 Photocatalyst Powder via sol-Gel Method: Effect of Hydrolysis Degree on Powder Properties
Research Output | Dar Al-hikmah Library | IIUM Only

Nanosized TiO2 powder was synthesized via sol-gel method using titanium tetraisopoxide (TPT) as the precursor. Mol ratios of water to TPT were varied from 1 (Powder A), 2 (Powder B), 3 (Powder C), and 4 (Powder D) to evaluate effect of hydrolysis degree. TG/DTA curves showed that amorphous phase turned to anatase crystal structure at ca. 415, 337,

Differences in Psychological Problems Between Low and High Achieving Students
Research Output | Dar Al-hikmah Library | IIUM Only

This study was conducted to examine the differences between low and high achieving students in their psychological problems i.e. depression, anxiety, and stress. 120 undergraduate students of the International Islamic University Malaysia (IIUM) were involved in this study. The Depression Anxiety Stress Scale (DASS) was used to measure the level of

Investigation of a Novel Type of Locomotion for a Snake Robot Suited for Narrow Spaces
Research Output | Dar Al-hikmah Library | IIUM Only

In snake robot research, one of the most efficient forms of locomotion is the lateral undulation. However, lateral undulation, also known as serpentine locomotion, is ill-suited for narrow spaces, as the body of the snake must assume a certain amount of curvature to propel forward. Other types of motion such as the concertina or rectilinear may be

Development of magnesium-Doped Biphasic Calcium Phosphate Through sol-Gel Method
Research Output | Dar Al-hikmah Library | IIUM Only

Calcium phosphate is an interesting material for bone implant applications, as it shows biocompatibility and bioactivity to tissue bone. Among calcium phosphate-based materials, biphasic calcium phosphate (BCP), a mixture of non-resorbable hydroxyapatite (HA) and resorbable tricalcium phosphate (TCP), has shown to possess unique characteristics app

A Hydrogel Stamper with Expandable Height and built-In Reservoirs for Patterning Biomolecules on 3d Topologies
Research Output | Dar Al-hikmah Library | IIUM Only

In this paper, we report on an expandable height hydrogel stamper with built-in reservoir that can be used to repeatedly (without frequent re-inking) stamp functional biomolecules on planar and non-planar surfaces. We have successfully patterned fluorescein isothiocyante (FITC) labeled antibodies (antibodies for O-antigens of Bradyrhizobium japonic

Remote Operation of CNC Milling Through Virtual Simulation and Remote Dekstop Interface
Research Output | Dar Al-hikmah Library | IIUM Only

Increasing the demand for effectively use of the production facility requires the tools for sharing the manufacturing facility through remote operation of the machining process. This research introduces the methodology of machining technology for direct remote operation of networked milling machine. The integrated tools with virtual simulation, rem

Controlled Potential Electrodeposition and Characterization of Znte Thin Films on Indium Tin Oxides
Research Output | Dar Al-hikmah Library | IIUM Only

Electrodeposition of ZnTe thin films by controlled potential method from aqueous solutions on ITO were done to investigate characteristics suitable as a window material in solar cells technology. The influence of bath temperature and deposition potential towards the Zn:Se ratio and the crystallinity are discussed. The electrodeposited films were in

Islamic Finance: Undergraduate Education
Research Output | Dar Al-hikmah Library | IIUM Only

Islamic finance literacy has become critical for the future growth of the Islamic financial sector in the twenty-first century. While a multi-pronged approach is called for, the focus in this paper is on the undergraduate programs in Islamic banking and finance. It analyses the state of teaching of Islamic banking and finance at the undergraduate l

Top Management Commitment Towards Quality Management in the Context of Malaysian Construction Organizations
Research Output | Dar Al-hikmah Library | IIUM Only

Top management commitment towards quality management is generally perceived as one of the key factors in determining its success. It has been observed that the local construction industry is facing a lot of quality issues. In relation to this, the authors are trying to perceive quality management in the context of Malaysian construction industry fr
