How well does political connection affect firms’ performance? / Nurul Azlin Azmi ...[et al.]
No full textThe purpose of this study is to examine the influence of political connections on firms’ performance by controlling the effect of board attributes and firms characteristics. Specifically, it is argued that politically connected firms enjoy a lot of benefit from the government and said to provide greater chances for the firms to increase their wealth. By using 156 public listed firms between the
study period of 2012 to 2017, this study maps out political connection based on the 13th Malaysian general election. The results reveal that the appearance of political connections on board give significant and negative effect on Tobin Q, while significant and positive effect on Return on Asset (ROA) and Return on Equity (ROE). Board independence is also significant to firms’ performance. This
result implies that political connections are favour for a better firm’s performance and not to firm’s value. The findings have an important implication to investors as it suggest that firms with political connection on board perform better

Book recommendation system using content-based filtering / Amalin Aliesya Mohd Azmi
No full textIn the modern world, where individuals may enter a library or browse online platforms without a specific book in mind. However, every reader has their own unique interests and preferences. With the help of Book Recommendation System, we can offer a solution by utilizing algorithms to suggest books based on a reader’s interests. With the aim of reducing the need to search for books and providing personalized recommendations, we propose the development of a website for students, designed to simplify the book selection process and eliminate confusion. By leveraging a user’s previous checkout history and search data, the website can recommend books based on the user’s interests. There are several models available for building such a system, using Content-based recommendation. However, most machine learning-based techniques rely on manually produced features derived from the input textual content. The models' performance was evaluated using a confusion matrix, where the accuracy, TF-IDF, cosine similarity, mean average precision were calculated. The highest accuracy obtained for the model is 82%. Overall, all objectives in this project are achieved successfully. However, there are also so limitations that needed improvement in the future. The major limitation is the algorithm running speed which can be a little slow when it comes to making recommendations. This is attributed to the intricacy of the content-based filtering algorithm, necessitating a substantial computational load on the central processing unit of a computer. In the future, the project can include the ability to explore multi-modal recommendation systems that consider not only textual information but also cover images, author details, and other relevant features to provide a more holistic understanding of user preferences
Effects of corporate governance and financial performance on fraudulent financial statements: evidence from Indonesia’s property, real estate, and building construction sectors / Reni Yendrawati , Reny Lia Riantika, Firkhansya Zuhaira Kusumadewi , Nurul Azlin Azmi and Zuraidah Mohd Sanusi
No full textThis study aimed to examine the effects of managerial and institutional ownership, and financial performance on fraudulent financial statements. Companies with weak governance and poor financial performance have a high tendency to partake in fraudulent activities as these factors create pressure and opportunity (fraud triangle theory) to mask financial figures. Weak governance sectors were chosen from the Indonesia Stock Exchange property, real estate, and building construction sectors. This study used a purposive sampling technique with predetermined criteria and employed panel regression analysis. The final panel data set consisted of 96 company-year observations. Managerial and institutional ownership had a significant and negative effect on fraudulent financial statements. Company leverage had a positive and significant relationship with fraudulent financial statements. Nevertheless, company profitability had no association with fraudulent financial statements. Furthermore, the interaction of company profitability strengthened the positive effect of managerial ownership and fraudulent financial statements. This study contributes to the literature by examining the corporate governance effectiveness in curbing fraudulent financial statements in selected sectors in Indonesia. In addition, this study offers practitioners insights into enhancing the effectiveness of internal and external governance mechanisms as well as the internal control systems in the companies
Growth kinetic of rhizopus sp. immobilised on loofah sponge for whole-cell biocatalyst in different cultivation media / Azlin Suhaida Azmi … [et al.]
No full textImmobilisation of filamentous fungi such as Rhizopus sp. onto biomass support particles (BSP) surface was studied as whole-cell biocatalyst. The function was to aid fermentation process. By using the microbial immobilisation process, the complex procedures of isolation, purification and immobilisation of extracellular enzyme can be avoided. Loofa sponge was selected as the BSP to aid in the immobilisation of the cells. In this study, the growth of immobilised Rhizopus sp. on loofa sponge was compared in four different cultivation media and the attachment of Rhizopus sp. on loofa sponge was investigated using scanning electron microscopy (SEM). The media used in this study were hydrolysed cassava starch, cassava dextrose, potato dextrose, and soy dextrose. The process condition and other parameters which were temperature, pH, inoculum dilution, and weight of loofa sponge, fixed at 30 °C, 7, 20 mL, and 2 g, respectively. The highest and lowest of maximum growth (ymax) of the immobilised cells were determined from potato dextrose and soy powder mixed with dextrose media, respectively at 1.5281 g/g and 1.0370 g/g. Whilst, the highest and lowest observed rate constant (k) were obtained from cassava starch mixed with dextrose and soy powder mixed with dextrose, which respectively at 2.9403 day−1 and −0.8763 day−1. SEM images showed the presence of mycelia attached to the loofah sponge after immobilisation process. In conclusion, Rhizopus sp. has been successfully immobilised on loofah sponge as a whole-cell biocatalyst
Sex change operation: different perspectives and challenges in Malaysia / Mohamad Zaki Azmi, Mohd Effendy Rosley and Nur Hasnifarina Ahmad Fauzi
No full textThe issue of legalizing sex change operation is not new in our country. Such operation was allowed until the National Fatwa Council (NFC) declared a fatwa on 1983 prohibiting Muslims from undergoing sex change operation. However, hermaphrodites
are excluded from this prohibition. By conducting this research, we aim to allow sex change operation not only for hermaphrodites but also to those who are suffering from
Gender Identity Disorder (GID) or Gender Dysphoria (GD). Both are acknowledged as psychological disorders, which lead to transsexualism. We referred to several statutes, decided cases, the Holy Quran, Hadiths and also books as our primary sources. Other
sources include law journals, medical journals, newspaper articles, online databases and also Internet sources. We also conducted several interviews with an academician, a book author and also a transsexual in order to get different opinions on the issue of sex change operation. We hope that this research will provide a better understanding on the issue of transsexualism in Malaysia. Since transsexuals in Malaysia are not allowed to be who they want to be, they are invariably involved in various social problems. Hopefully, this research will open the eyes of the government and also the society on the importance of addressing this issue. Hopefully they will realize that transsexuals are normal human beings who deserve to be respected
Truss Disposition Optimization Using the Linear Extended Interior Penalty Function
No full textThis paper describes the development of truss optimization by finding its optimum topology (member disposition). The objective of this work is to obtain the truss with minimum weight that able to meet its design requirement (design constraints). Optimization is a mathematical technique used to find an optimum design, a design that minimize a certain objective function but still meet its design constraints. In this research, the objective function was the weight of the structure while the constraints were strength and displacement. Optimization was done by removing members which do not contribute to the load carrying capacity. Through conventional member size optimization non contributing members were identified and deleted. Linear Extended Interior Penalty Function was utilized to accomplish the mission. The truss structural responses were found by Finite Element Analysis coupled with an approximation procedure. Examples of a three-bar and six bar truss structures were demonstrated. Results showed that the truss topology could be optimized by members deletion strategy using the optimization procedure reported in this paper.</jats:p

Identification of planck’s constant by Light Emitting Diodes (LEDS) / Nurain Azmi ... [et al.]
No full textIn this paper, a simple analysis yet a straight forward method of determining the Planck’s constant by evaluating the stopping potential of five different colors of light emitting diodes (LEDs) is presented. The study aimed to identify the Planck’s constant based on the relationship between the potential difference of LEDs to their respective frequencies under room temperature with low illumination of ambient light by applying a simple theoretical analysis. The experiment was performed by connecting the circuit in series connection and the voltage reading of LEDs were recorded and then presented in a graph of frequency, f versus stopping voltage, Vo. To determine the Planck’s constant, the best fit line
was analyzed and the centroid was also identified in order to find the minimum and maximum errors due the gradient of the graph. From the analysis, results showed that the Planck constant value was (5.997 ± 1.520) × 10–34 J.s with approximately 10% of deviation from the actual value. This demonstrates that a simple analysis can be utilized to determine the Planck’s constant for the purpose of the laboratory teaching and learning at the undergraduate level and can be served as a starting point for the students to understand the concept of quantization of energy in Modern Physics more effectively. This is to further suggest that the Planck’s constant can be identified via a low-cost and unsophisticated experimental setup
