The purpose of this research project is to investigate the effects of amount of catalyst, the ratio of solid to methanol and different temperature on the biodiesel yield. Solid coconut waste and heterogeneous catalyst derived from the waste, which is calcium oxide (CaO) are used to produce biodiesel and also examine the kinetics of the reactive ext

The aim of this study is to optimize the transesterification using potassium hydroxide (KOH)-supported polyvinyl alcohol to ease the separation process between glycerol and biodiesel. The design of experiment used was factorial composite design (FCD) and the effects of the amount of catalyst ranging from 0.5 wt% to 10 wt%, methanol to oil ratio fro

In this study, heterogeneous catalysts were synthesized from mixture of calcined solid coconut waste and eggshells as a catalyst for the transesterification of palm oil. Response surface methodology (RSM) based on central composite design (CCD) was used to optimize the amount of catalysts (coconut waste:calcined eggshells ratio) for production of b

The waste food material namely fish bone is screened for biodiesel synthesis by transesterification reaction to achieve the highest biodiesel yield. The fish bone was chemically treated with Al(NO3)3.9H2O to enhance the biodiesel yield. The solid oxide materials were calcined at 900 °C for 2 - 4 h to convert CaCO3 to CaO species. Transesterificati

A kinetic study of in situ transesterification of solid coconut waste was conducted at 55-65°C. The mixing is kept constant at 350 rpm. The maximum conversion of 38.3% was obtained at 60°C, 1:10 solid to methanol ratio and 5 weight (wt.) % of catalyst. The feedstock was obtained after coconut milk extraction. The conversion of solid coconut waste

Carbon Fibre Reinforced Plastic (CFRP) is extensively used nowadays especially in the industries due to its desirable properties of high strength, light weight and high resistance to corrosion. However, the machining of CFRP composites requires great specification and requirement as it is difficult to be machine. Besides, improper technique and par

Financial ethics emphasises the importance of developing and sustaining ethics in financial transactions. The term “financial ethics” can be understood as ethics as it is applies to ethical and moral issues in finance. In the context of Islamic finance, Islamic financial institutions that are governed by the principle of the sharī‘ah, are ex

Ethics is a discipline that deals with “the science of conduct”, which is concerned with two opposing dimensions of moral action such as right or wrong, good or bad, and virtue or vice. In the context of Islamic finance, ethics has become a vital component in the financial services sectors in order to provide “value” for consumers. Unfortun

Male-to-female transgenders are discriminated in Malaysia due to their gender expression, their involvement in the sex trade, and the high prevalence of HIV infection in this community. They are burdened by many health issues including HIV and sexually transmitted diseases, psychiatric problems, substance abuse, and complications resulting from fem

Medical disputes amongst medical professionals and their patients are seen to be inevitable, particularly, when patients suffer adverse outcome in medical treatment. The occurrences of death and physical injuries tend to trigger claims in the court of law. Consequently, medical professionals may be subjected to criminal proceedings although their a
