Biodiesel is biodegradable and nontoxic alternative fuel for diesel engine which has become more attractive to replace diesel fuel. In this study, vegetable oil was identified as potential sources for biodiesel production. The production of biodiesel from different non-edible oilseed crops has been extensively investigated for the past few years. Thus, the aim of this study is to critically review on the characteristic of the potential biodiesel and biodiesel diesel blends fuel properties. The aspects of this study cover the biodiesel production and fuel properties of biodiesel and biodiesel blends. Besides, some studies have shown that there is a direct correlation between fatty acid composition and biodiesel properties. The fuel properties of biodiesel blends fuel were very close to diesel fuels and satisfied ASTM 6751 and EN 14214 standards. As a final note, further study on the utilization of biodiesel blends needs to be carried out in order to ensure optimization in engine operation. © 2013 Elsevier Ltd.

Biodiesel production from non-edible vegetable oil is one of the effective ways to overcome the problems associated with energy crisis and environmental issues. The non-edible oils represent potential sources for future energy supply. In this study, the physical and chemical properties of crude Jatropha curcas oil (CJCO), crude Sterculia foetida oil (CSFO) and crude Ceiba pentandra oil (CCPO) and its methyl ester have been studied. The acid values of three oils were found to be 12.78 mg KOH per g, 5.11 mg KOH per g and 11.99 mg KOH per g which required acid-esterification and alkali-transesterification process. Acid value was decreased by esterification process using sulfuric acid anhydrous (H2SO4) as a catalyst and alkaline (NaOH) catalyst transesterification was carried out for the conversion of crude oil to methyl esters. The optimal conditions of FAME yield achieved for those three biodiesel were 96.75%, 97.50% and 97.72% respectively. Furthermore, the fuel properties of J. curcas methyl ester (JCME), S. foetida methyl ester (SFME) and C. pentandra methyl ester (CPME) were determined and evaluated. As a result, those produced biodiesel matched and fulfilled ASTM 6751 and EN 14214 biodiesel standards. Based on the results, JCME, SFME and CPME are potential non-edible feedstock for biodiesel production. © 2013 Elsevier Ltd. All rights reserved.

Electricity consumer dishonesty is a problem faced by all power utilities. Finding efficient measurements for detecting fraudulent electricity consumption has been an active research area in recent years. This paper presents a new approach towards nontechnical loss (NTL) detection in power utilities using an artificial intelligence based technique, support vector machine (SVM). The main motivation of this study is to assist Tenaga Nasional Berhad (TNB) Sdn. Bhd. in peninsular Malaysia to reduce its NTLs in the distribution sector due to abnormalities and fraud activities, i.e., electricity theft. The fraud detection model (FDM) developed in this research study preselects suspected customers to be inspected onsite fraud based on irregularities in consumption behavior. This approach provides a method of data mining, which involves feature extraction from historical customer consumption data. This SVM based approach uses customer load profile information and additional attributes to expose abnormal behavior that is known to be highly correlated with NTL activities. The result yields customer classes which are used to shortlist potential suspects for onsite inspection based on significant behavior that emerges due to fraud activities. Model testing is performed using historical kWh consumption data for three towns within peninsular Malaysia. Feedback from TNB Distribution (TNBD) Sdn. Bhd. for onsite inspection indicates that the proposed method is more effective compared to the current actions taken by them. With the implementation of this new fraud detection system TNBD's detection hitrate will increase from 3% to 60%. © 2010 IEEE.

Tenaga Nasional Berhad (TNB) has warned the public not to fall for any e-mails, claiming to have been sent by them, offering exclusive rewards such as cash. The e-mail apparently offers recipients RM150,000 in cash and according to TNB senior general manager of corporate affairs and communications Datuk Mohd Aminuddin Mohd Amin, this was not the first time such an e-mail has been sent. “It is a fake e-mail spread by irresponsible quarters to steal personal information. “All communication via e-mail by TNB is done using the company’s e-mail address and not e-mail addresses like gmail, yahoo, Hotmail, outlook.my and others,” he said in a statement today. TNB said a complaint has already been made for further action to be taken by the Malaysian Communications and Multimedia Commission (MCMC). He also advised the public not to reveal any personal information to any quarters they were unfamiliar with. For further information, customers can contact TNB Careline at 1-300885454 or on Facebook (TNB Careline).

: Following the decision to buy 1Malaysia Development Berhad’s(1MDB) largest stake in a power plant project, Tenaga Nasional Berhad (TNB) now intends to raise about RM10 billion in an Islamic bond issue.If the plan goes through, the bond would be the biggest sukuk globally this year, advancing the sukuk market after the issuance dropped in the first quarter to a record low in four years, Reuters reported.However, sources said the plans for the issue are still in preliminary stages.According to the report, TNB’s biggest shareholder, Khazanah Nasional Berhad is considering at a single issue bond instead of a series of bonds.Khazanah has sent a few proposals to different banks, sources told Reuters.Earlier this month, TNB decided to purchase 1MDB’s 70 percent stake in a Greenfield 2,000 MW coal-powerd plant, 3B.The transaction between TNB and 1MDB is believed to alleviate 1MDB by scaling down its debt of over than $11billion (RM4, 1163, 650,000).However, TNB’s CEO Datuk Seri Azman Mohd has denied the claims that the purchase of 3B is not a bailout for the troubled investment company.
