The leaves and stem bark extracts of B. penangiana were screened to evaluate their antioxidant, antimicrobial,tyrosinase, lipoxygenase, and acetylcholinesterase activities. Evaluation of antioxidant activities were tested against DPPH, ABTS, and total phenolic content (TPC) assays. The antimicrobial activity were investigated by microdilution method for determination of MIC, MBC, and MFC. Tyrosinase and lipoxygenase inhibitory activities were analysed using mushroom tyrosinase and lipoxygenase enzymes, respectively. In addition, the acetylcholinesterase activity was tested using cholinesterase enzyme. The methanol extract of stem bark showed the highest phenolic content (176.8 mg GAE/g), DPPH free radical scavenging (IC50 95.5 μg/mL), ABTS (IC50 124.8 μg/mL), and lipoxygenase inhibitory activity (I: 46.3%). All extracts showed from moderate to weak activity with MIC/MBC/MFC values in the ranged of 62.5-1000 µg/mL. The ethyl acetate stem bark extract revealed the highest percentage i.....

Objective – The removal of fuel subsidies by the Malaysian government in 2014 has been implement with the managed float system for fuel prices. Methodology/Technique – This study investigates the impact of the managed floating system of crude oil prices on the Malaysian economy using ARDL approach by looking at macroeconomic variables such as inflation, economic growth and unemployment rates. Findings – The results show that all of the variables have short lived relationship with oil prices whereby inflation and economic growth are positively related to oil prices. However, unemployment rate has a negative relationship with the changes of WTI crude oil prices. Novelty – The major input in the economy of Malaysia contributes to a positive relationship between inflation and oil prices, whilst the contribution of Malaysia being an oil-producing country results in the positive relationship of economic growth and oil price. Likewise, as oil prices are high, the increase in demand.....

Arabic language is an important tool in learning and teaching Islamic Legal Sciences. Its importance that it is the language of the Holy Qur'an, which is the main source of Islamic texts and provisions. Therefore, to understand these texts, the learners must understand Arabic language. The aim of this study is to investigate the function of Arabic language as a tool used in teaching Islamic Legal Sciences in the International Islamic University of Malaysia. The researchers designed a questionnaire and was distributed among the students of Arabic Language to investigate the efforts of International Islamic University of Malaysia in teaching Arabic language especially within issues that are related to understanding the Quran.  ..

The purpose of this study is to develop and evaluate Multi-frames Video Recorded Experiments (MFVREs) as self-learning materials for Electricity topic of the Malaysian Form Five Physics curriculum. The development of MFVREs consisted of eight steps; selecting topic, selecting related experiments, preparing apparatus and materials for experiments, testing experiments, setting up recording apparatus, recording experiments, editing MFVREs and testing MFVREs. The MFVREs comprised of four subtopics; electric field and charge flow, relationship between current and potential difference, series and parallel circuits and electromotive force and internal resistance. The compatibilities of MFVREs as selflearning materials were evaluated from their effectiveness’s towards students’ achievement and students’ perceptions towards MFVREs. The samples of this study consisted of 40 Form Five students of a secondary school in Slim River and they were equally and randomly divided into the experiment.....

Mobile Multihop Relay (MMR) network is an attractive and low-cost solution for expanding service coverage and enhancing throughput of the conventional single hop network. However, mobility of Mobile Station (MS) in MMR network might lead to performance degradation in terms of Quality of Service (QoS). Selecting an appropriate Relay Station (RS) that can support data transmission for high mobility MS to enhance QoS is one of the challenges in MMR network. The main goal of the work is to develop and enhance relay selection mechanisms that can assure continuous connectivity while ensuring QoS in MMR network using NCTUns simulation tools. The approach is to develop and enhance a relay selection for MS with continuous connectivity in non-transparent relay. In this approach, the standard network entry procedure is modified to allow continuous connectivity with reduced signaling messages whenever MS joins RS that is out of Multihop Relay Base Station (MRBS) coverage and the relay selection is.....

A study on the alkaloid composition on the Malaysian Annonaceae species, i.e Popowia perakensis King has been carried out. Barks of Popowia perakensis were extracted with hexane, dichloromethane and methanol, respectively. Dichloromethane extract further underwent the acid base treatment to give the alkaloidal crude extract. Isolation of compounds was carried out using various chromatography techniques including column chromatography and thin layer chromatography. Spectroscopic methods notably 1 H, 13 C NMR, IR, UV and GC-MS spectroscopy were utilized to identify pure compounds in addition to comparison of reported data. Two azaanthraquinones alkaloids namely cleistopholine 1 and 6-methoxycleistopholine 2 together with simple isoquinolone alkaloid, N-methylcorydaldine 3 had been isolated. All three alkaloids are known but they were isolated for the first time from this species. Cleistopholine 1 was tested for Dipeptidyl peptidase IV (DPP IV) inhibition to investigate its potential anti.....

This  study  examined  the  effect  of  Mindfulness  Acceptance  Commitment-Physical  (MAC-P)  on anaerobic performance. The MAC-P specifically designed for anaerobic training, and has its validity and  reliability.  The  study used  non-randomized  control  group  pretest-posttest  design.  Research instrument consisted of Wingate Test to evaluate anaerobic performance in terms of peak power, mean power and anaerobic fatigue index. Subjects were semester one Coaching Science students from Sultan Idris Education University, divided into MAC-P (n = 21), PST (n = 21) and control (n = 21) group.  Analysis  of  Covariance  (ANCOVA)  showed  significant  effect  of  the  intervention  on  the achievement of post anaerobic peak power [F(2, 59) = 19.18, p < 0.05] and mean power [F(2, 59) = 3.60, p < 0.05]. However, the interventions did not have significant effect on post anaerobic fatigue. In conclusion, the MAC-P has prominent effect on  anaerobic performance.....

The aim of this study is to examine the significant of Islamic ethics in the development of ethicalaccounting graduates through accounting educator’s perspectives. This paper used a survey questionnaire to collect data from accounting educators from eight public universities in Malaysia. Survey items were developed based on Islamic ethics instrument adapted from AAOIFI Code of Ethics for Accountants and Auditors (1998), and Accounting Ethical Development model (Fisher et al., 2005). The findings provide evidence that accounting educators have similar consensus that Islamic ethics principles were acceptable and important to be incorporate in accounting curriculum in order to generate ethical future accountants. Further, respondent encourage accounting educators to integrate Islamic ethics in their teaching and learning process. Overall, the findings of the study are expected to provide a guideline for the university administrator to enhance the improvement of accounting curriculum..

Identifying the local time scale of the torrential rainfall pattern through Singular Spectrum Analysis (SSA) is useful to separate the trend and noise components. However, SSA poses two main issues which are torrential rainfall time series data have coinciding singular values and the leading components from eigenvector obtained from the decomposing time series matrix are usually assesed by graphical inference lacking in a specific statistical measure. In consequences to both issues, the extracted trend from SSA tended to flatten out and did not show any distinct pattern. This problem was approached in two ways. First, an Iterative Oblique SSA (Iterative OSSA) was presented to make adjustment to the singular values data. Second, a measure was introduced to group the decomposed eigenvector based on Robust Sparse K-means (RSK-Means). As the results, the extracted trend using modification of SSA appeared to fit the original time series and looked more flexible compared to SSA...
