Tribological Study of A1 Based Natural Fibre Reinforced Composite Brake Pad Materials
Research Output | Dar Al-hikmah Library | IIUM Only

Tribological behavior of Al–based natural fiber reinforced composites (NFC) brake pad materials was studied using CHASE Dynamometer machine in accordance with Society of Automotive Engineer standard procedure SAE J661. In this study, the NFC sample with a size of 25 mm x 25 mm x 6 mm was fabricated using powder metallurgy route for friction and w

Extraction of Microcrystalline Cellulose (Mcc) from Cocoa Pod Husk via Alkaline Pretreatment Combined with Ultrasonication
Research Output | Dar Al-hikmah Library | IIUM Only

The aim of this study was to extract microcrystalline cellulose (MCC) from cocoa pod husk (Theobroma cacao L.) via alkaline treatment and ultrasonication. The sieved cocoa pod husk (CPH) was treated with 2% w/v sodium hydroxide (NaOH) for 5h at 800C in a water bath. Then, it was bleached by aqueous dilution of hydrogen peroxide at 75oC followed by

Abundance of sulfur-Degrading Bacteria in a Benthic Bacterial Community of Shallow Sea Sediment in the off-Terengganu Coast of the South China Sea
Research Output | Dar Al-hikmah Library | IIUM Only

This study for the first time provides insight into the bacterial community in the benthic region of the Off-Terengganu Coastline, which is considered to be anthropogenically polluted due to heavy fishing vessel commotion. Subsurface bacteria were randomly collected from two locations at different depths and were examined using the 16S rDNA V3-V4 m

Why do Taxpayers Comply: Evidence from Indonesia
Research Output | Dar Al-hikmah Library | IIUM Only

This paper aims to identify the reasons used by taxpayers to become a compliant taxpayer, and whether these reasons are affected by demographic factors. Five reasons were used - fairness on the distribution of tax burden, fairness of the government in utilising government revenue, peer influence, sanctions and non-tax macro factors. Data was collec

Cholesterol Lowering in intermediate-Risk Persons Without Cardiovascular Disease
Research Output | Dar Al-hikmah Library | IIUM Only

Previous trials have shown that the use of statins to lower cholesterol reduces the risk of cardiovascular events among persons without cardiovascular disease. Those trials have involved persons with elevated lipid levels or inflammatory markers and involved mainly white persons. It is unclear whether the benefits of statins can be extended to an i

Nightscape of Urban Squares in Landscape Architectural Design: Analysis and Evaluations on Nightscape of Merdeka Square in Kuala Lumpur
Research Output | Dar Al-hikmah Library | IIUM Only

Nightscape plays an important role in enhancing the quality of environment especially for urban settings such as the city squares. Declining awareness and negative perceptions may lead to a series ground of crimes, fear and lack of sense of place. The aim of the study is to redefine urban nightscape in realizing a sustainable green and energy-effic

Exports, Imports, Exchange Rates, Gross Domestic Investment and Growth: Empirical Evidence from Cameroon
Research Output | Dar Al-hikmah Library | IIUM Only

The main objective of this study is to investigate whether exports, imports, exchange rates, and gross domestic investment are important in determining economic growth in Cameroon. The Johansen tests of co-integration suggest the presence of a long-run relationship among the variables and all the long-run coefficients have the expected signs and si

Survival and Growth Rates of Sutchi Catfish (Pangasianodon Hypophthalmus) Juveniles Under Different Light Wavelengths and Intensities
Research Output | Dar Al-hikmah Library | IIUM Only

This study report the effects of light intensity on the optimum light wavelength and intensity on the survival rate, specific growth rate, and production index of sutchi catfish (Pangasianodon hypophthalmus, Sauvage, 1878) juveniles. The sutchi catfish juveniles (69 days old) with average initial body length of 5.14 cm and body weight of 1.11 g wer

Possibility of Using Interdigital Sensor (Ids) in Estimating Different Level of Blood Glucose
Research Output | Dar Al-hikmah Library | IIUM Only

This paper presents the relationship of an effective capacitance of the interdigital sensor (IDS) with effective relative permittivity (ε_re) of the material under test (MUT). The relationship of the effective capacitance of the interdigital sensor against the relative permivittivity ε_re is examined by using the curve fitting tool provided by MA

Cortisol (Stress) Level of Sutchi Catfish (Pangasianodon Hypophthalmus) Juvenile Under Different Light Wavelengths and Intensities
Research Output | Dar Al-hikmah Library | IIUM Only

Light wavelengths and intensities affect the cortisol (stress hormone) levels in fish. Thus, this study aims to determine the optimum light wavelength and intensity to re-duce stress of juvenile sutchi catfish, Pangasianodon hypophthalmus. The sutchi cat-fish juveniles (35 days post hatching) were reared for 28 days (20 individuals/30 L) under five
