Nurliyana Abdullah

Abstract: Online detection of blockage, or build up deposit in the pipelines using non-invasive gamma ray transmission technique is one of the most useful applications in many industrial processes. While this technology is very demanding in petroleum and petrochemical industries, it is not being optimized to its full potential. One of the main reasons is the lack of functionality and flexibility of the conventional pipe scanner. Therefore, a new design of pipe scanner called FLEX-Si is proposed to address the problems of the conventional scanner. This new scanner is capable to supports the original functions of the old one, but at the same time offers several technical advantages. To validate the result from the new design, an experiment has been made using both scanners. The result is satisfactory and comparable to the conventional scanner, but can be improved with better alignment.

Recycling Waste Tires: Effect of Radiation Sensitizers and Electron Beam Irradiation of Properties of Reclaimed Waste Tire Rubber/EVA

Blends

S. Ramarad, C.T. Ratnam, M. Khalid, & A.L. Chuah

Abstract: Non-degradable waste tire generation around the world is growing at an alarming rate. Diversifying the recycling route of these waste tires is essential to solve the problem. To address the issue, this study utilized radiation sensitizers and electron beam irradiation to enhance the poor properties of reclaimed waste tire rubber/poly(ethylene vinyl acetate) (RTR/EVA) blends. The RTR, EVA and radiation sensitizers were mixed in the internal mixer followed by electron beam (EB) irradiation with doses ranging from 50 to 200 kGy. Radiation sensitizers loading was fixed at 4 wt%. The degradation and stability in RTR were studied in term of mechanical and morphological properties. Electron beam irradiation revealed the presence of radical stabilizing and scavenging additives within RTR which retards the crosslinking process in RTR. Though chain scissions were predominant; study showed the replacement of S-S and S-C bonds with stronger and stiffer C-C bonds ensures the retention of RTR properties upon irradiation. However, RTR still suffered from further oxidative degradation from irradiation in air. Radiation sensitizers, trimethylol propane triacrylate (TMPTA) and tripropylene glycol diacrylate (TPGDA), were used to accelerate the irradiation induced crosslinking in RTR and blends. Presence of radiation sensitizers leads to simultaneous improvement in toughness and tensile strength of RTR and blends. Elastic capacity of RTR phase was restored and interfacial adhesion enhanced in the presence of radiation sensitizers. These findings validated the feasibility of using ionizing radiation for recycling inferior waste polymers into higher quality material.

Elements of Knowledge Management (KM) in Technical Writing Publication

Nor Azlina Nordin, Mohd Hafizal Yusof, Normazlin Ismail, Wan Jazlina Wan Ahmat & Norhidayah Jait

Abstract: Knowledge Management (KM) is a holistic approach in the objective of achieving the goals set out in the business or organisation. Nuclear Knowledge Management should be practiced and applied in managing information and knowledge among researchers by Nuklear Malaysia, the agency under the Ministry of Energy, Science, Technology, Environment and Climate Change (MESTECC). Furthermore, Nuklear Malaysia itself is a unique agency where nuclear-based knowledge has been intensively developed in various fields for over 45 years of operation. Efforts to sustain and share knowledge based on nuclear technology from specialist researchers need to be implemented before they retire. Therefore, elements of knowledge management such as knowledge acquisition, storage and preservation, knowledge sharing, networking, story-telling, coaching and mentoring will be used in this process. Through the KM initiative, a project has been planned and implemented in an effort to get the information and knowledge of researchers on tacit and explicit, namely Book Writing. Expert and knowledgeable researchers in specific areas are encouraged to write technical books and will be published in collaboration with Nuklear Malaysia and Dewan Bahasa dan Pustaka (DBP). Now, some books have been published and some are still in the process of publishing. This paper will clarify the role of the KM elements in ensuring that the publication of this technical book can be successfully implemented as well as challenges and measures to ensure that this business can run smoothly and meet its objectives.

Abstract: This research focusing on the recovery of thorium (Th) from Malaysian xenotime ore. Besides becoming ideal nuclear fuel for next generation reactors, thorium in thoriated electrodes have been manufactured in Spain for tungsten inert gas welding. Thoria or thorium oxide (ThO2) were added to help gas mantles burn hotter and brighter. Therefore, it is essential to establish a method to crack and extract thorium from abundant earth’s crust need to embark non-nuclear applications of thorium. In this study, Malaysian xenotime were collected from Kinta Valley, Perak and undergo alkaline fusion process at 350 °C with ratio of xenotime to sodium hydroxide (NaOH) were 1:2 and 1:3. The fusion duration (2, 3, 4 and 6 hours) were varied. The fused samples were undergone leaching process by HCl for 6 hours. The yellow solution obtained were quantitate by energy dispersive X-ray fluorescence (EDXRF) to measure the Th recovered. The optimum recovery of thorium achieve upon fusing 1 part of xenotime to 3 parts of NaOH for 4 hours at 350 °C.

Alkaline Fusion of Malaysian Monazite and Xenotime for The Separation of Thorium and Uranium

Jacqueline Kones, Norhazirah Azhar, Nur Aqilah Sapiee, & Khaironie Mohamed Takip

Abstract: The waste produced in the rare earth industry can be radioactive and posed hazard to the environment. This is due to the presence of element thorium and uranium in the minerals. Xenotime and monazite are among the examples of rare earth element bearing minerals that can be found in Malaysia. Extracting these to minerals can benefit the environment by reducing the amount of radioactive elements in the wastes produce other than processing thorium and uranium for the purpose of nuclear fuel. The objective of this study was to study the separation of thorium and uranium in local monazite and xenotime via alkaline fusion process. The minerals are initially fused with pelet sodium hydroxide at 350°C for three hours before leaching with 6 M hydrochloric acid. Two complexes containing thorium and uranium were obtained separately through selective precipitation using oxalic acid and ammonia solution which were later analysed for its content using Energy Dispersive X-ray Flourescence (EDXRF). The result obtained shows that it is possible to separate thorium and uranium. However, the conditions used in this technique were found to be more suitable for xenotime.

Why Media and Science Communication Matters to Women in STI?

Abstract: In spite of the growing number of girls at universities, it is a

worldwide phenomenon that we still have a higher proportion of men in

high paying STEM-related careers and at decision making levels. The

leaky pipeline for women in STEM is widely highlighted. A number of ap-

proaches have also been put forward, including policy measures by many

governments around the world. In the U.S., even the portray of women

characters in STEM-related movies is studied to show how it impacts the

public perception of STEM careers and gender stereotyping in these

fields. White House Fact Sheet presents the airtime given to female char-

acters and the role they play in STEM movies. It is interesting to note that

movies like CSI played a role in the increase of number of girls applying

for forensics courses at the universities between 2000-2005. Engaging the

media, both mainstream and social media could help put women scientists

in the forefront and in the public eye. This helps them to build their network

and confidence and be role models for other young women. Understand-

ing the media and honing their science communication skills will be benefi-

cial for women. Social media is another ready platform that is yet to be

exploited. The brain drain among woman professionals is high due to pa-

rental commitments and pressure at work. Perseverance to stay in the job

market could be strengthened if women develop their careers around their

passion and family commitments. This should be coupled with developing

their value and skills that will give them the negotiation power. The presen-

tation intends to highlight media as one of the partners for women to put

themselves in the STEM radar outside their usual network system and be

noticed.

Effect of Gamma Irradiation of Waste Tire Dust on the Properties of Ethylene Vinyl Acetate/Waste Tire Dust, Eva/Wtd Blend

Chantara Thevy Ratnam, Pairu Ibrahim, Sivanesan Appadu, Khairul Hafiz & Noraini Sulaiman

Abstract: Scrap tires are valuble and viable resource; the challenge today is to find best way to utilize them in a wide range of applications Recycling of discarded tires is a challenging process to accomplish due to the highly crosslinked nature of tires. There have been substantial progresses in investigating new technology to utilize the scrap tires. One of the promising alternatives to utilize waste tire rubber is the preparation of thermoplastics elastomers. Attempts have been made to blend the scrap rubber, namely waste tire dust, WTD with thermoplastics such as ethylene vinyl acetate (EVA) to produce thermoplastic elastomers with a range of properties. However the EVA/WTD blend found to exhibit poor compatibility and homogeneity which resulted in poor mechanical properties. Studies indicated that the EVA/WTD based thermoplastic material can be crosslinked by electron beam irradiation. In this work the effect of pre-irradiation of waste tire dust (WTD) on the homogeneity and compatibility of Ethylene Vinyl Acetate/WTD was investigated. WTD of 80 mesh particle size was irradiated by gamma ray from Cobalt 60 source at doses of 200kGy, 400kGy, 600kGy, 800kGy and 1000kGy The irradiated WTD was then melt blended with EVA by using a Haake mixer at 50 rpm, 120°C for 10 minutes. All the samples were tested for elongation at break, tensile strength, hardness, impact strength and morphological properties. Interestingly, an upward trend was observed for tensile strength, elongation at break and hardness of the EVA/WTD blends with irradiation dose. It was evident from the transmission electron microscopy images that the dispersion of WTD in EVA was improved upon pre-irradiation of WTD. .

Antimicrobial Susceptibility Testing of Silver Nanoparticles Synthesized Using γ Irradiation

Anis Nadia Mohd Faisol Mahadeven & Salmah Moosa

Abstract: A study on the antimicrobe susceptibility was undertaken to determine the antimicrobial susceptibility of silver nanoparticles synthesised physically using γ-irradiation on test microorganism. Two test microbes from Gram positive and Gram negative bacterias namely Enterococcus faecalis (Gram positive) as well as Escherichia coli (Gram negative) were used as test microorganisms. The susceptibility of the microorganisms to varying concentrations of silver nanocomposites (Ag/Kln) and silver bionanocomposites (Ag/Kln/Cts) were compared to those symthesized chemically. The study was perfomed using agar diffusion method – well variant, and the results were observed. Concentrations of silver nanoparticles used were 0.5 % Ag/Kln, 1.0 % Ag/Kln, 2.0 % Ag/Kln, 5.0 % Ag/Kln, and 10 % Ag/Kln for chemical synthesis and irradiation doses used for physical synthesis are 7 kGy, 13 kGy, 20 kGy, 30 kGy, 40 kGy, 50 kGy, 65 kGy and 80 kGy . Different concentrations of silver nanoparticles were compared to silver bionanocomposites (Ag/Kln/Cts) of the same concentration and doses as Ag/Kln as well as to controls using kaolinite (Kln), chitosan (Cts), sterile distilled water and commercially available Gentamicin disk. Observation on well diffusion variant showed significantly large zone of inhibition for physically synthesized nanoparticles which indicates higher antimicrobial activity. Chemically synthesized nanoparticles using the same experimental set up however showed relatively smaller zone of inhibition. The factors that contributed to the difference in the size of inhibition zone and thus antimicrobial susceptibility were investigated and will be discussed in this paper. .

Influence of Particle Size on Mechanical Properties of Carbon Dust Reinforced High Density Poly Ethylene

Norshafarina Ismail & Chantara Thevy Ratnam

Abstract: Influence of different particle sizes of carbon dust has been studied to find applications as a filler material in thermoplastic matrix. Carbon dust is an accruing chips and dust from milling operation of carbon reinforced plastics (CFRP). Test specimens were prepared by blending high density polyethylene, HDPE and carbon with melt mixing technique at 150°C for 10 minutes and subsequently hot pressed before subjected to respective mechanical testing. This new approach to directly reuse the waste carbon dust with particle size of <38µm found to render higher mechanical properties as compared to coarser particle size (100µm). Results revealed that the carbon dust reinforced HDPE has improved material properties, e.g. increase impact and Young’s modulus independence of their filler loading. Irradiation with electron beam aims to crosslinking of the compound has found to cause further enhancement in the mechanical properties of the HDPE/carbon dust due to radiation-induced crosslinking of the HDPE matrix.

Walking One More Mile : A Personal Narrative of Work-Life Balance

Abstract: The integration of work and home life (or the effective manage-

ment of a career and family life) remains a perennial topic amongst profes-

sional working women all over the globe. Issues such as meeting pres-

sures, living in disequilibrium, compliance to professional life and en-

hanced productivity coupled with fulfilling family obligations still fins space

for research to find workable and sustainable solutions. While there is a

wealth of publications dealing with work-life balance many professional

women find resonance with publications that share personal narratives of

coping with pressure and expectations rather than studies based on wom-

en, treating them as study subjects . This presentation is a personal narra-

tive of managing work-life balance in a research-academic environment in

a cultural milieu where family values and relationships are very important.

This narrative is more often not finding the energy and passion to literally

“walk one more mile”.

Optimizing the Efficiency of A Dielectric Barrier Discharge Reactor for Removal of Nitric Oxides in Gas Phase

Siti A’iasah Hashim, Wong Chiow San & Mhd Radzi Abas

Abstract: A dielectric barrier discharge (DBD) reactor was built and used to remove nitric oxides in gas phase. In the preliminary work, it was found that the DBD reactor can used for direct processing of contaminated air stream. It was observed that if the applied energy is sufficiently high, reduction can overcome the oxidation process. The other characteristics that can affect the efficiency of the reactor are the processing flow rate, number of DBD tubes used and how the tubes are connected. The composition of the feed gas also plays important role. To improve the efficiency, more tubes were added and configured in combination of serial and parallel connections to achieve the best result. The reactor was found to be most efficient when using 6 tubes configured to have 2 sets of 3 tubes in series connected in parallel. The maximum flow rate that can be treated is 5 scfh. When operated with the optimum input voltage of 32 kV, the reactor can remove up to 80% nitric oxide in the reduction mode. This means that the energy is sufficiently high to sustain the reduction mode and prevent further oxidation.

Sustainable Safety of Aquatic Biota Through Continuous Research Study

Zal U’yun Wan Mahmood & Norfaizal Mohamed @ Mohamad

Abstract: Land and marine industry activities produce pollutants and large volume of waste. Hence, the leaching of these pollutants will slowly contaminates surface and ground water bodies and later spread to the coastal and ocean. Usually, the pollutants accumulate in aquatic biota and end up to be part of the human’s food chain. In sustaining the safety of aquatic biota, continuous research studies have performed and focused with the objective is to evaluate radiological dose and risk of aquatic biota that was exposed to waterborne radionuclides in the laboratory modeling the actual mechanism of biokinetic accumulation in biota. In general, the levels of accumulated radionuclides in aquatic biota are not significant and safe to eat. Meanwhile, experiments in laboratory bioaccumulation can reflect the actual kinetic mechanism in aquatic biota exposed to radioactive contamination and toxic substances.

Calibration of Thyroid Counter System for Assessing Intake of Iodine-131 in Thyroid Organ

Nurul Nadiah Rapie, Norhayati Abdullah & Nur Syahira Abu Bakar

Abstract: Thyroid counter system is a device used to monitor the radiation exposure especially internal contamination for the radiation workers. Ideally, the thyroid uptake systems should be calibrated regularly to ensure that they are operating correctly and the overall characteristics of the instrument are within acceptable limits. In order to make sure the consistency and reliability of measurements, this system is maintained and calibrated using Cs-137 disc source. A daily quality assurance (QA) includes energy calibration, energy resolution, constancy and chi-square are performed to test the performance of the system. The results should comply with the standard protocol of thyroid counter calibration provided by the Ministry of Health and the tolerance limit given by the manufacturer. In addition, the detector efficiency and minimum detectable activity (MDA) at various neck phantom to collimator distance (NCD) and at different counting time are determined. Finally, the consistency of background radiation and environmental conditions in the laboratory are monitored. The results show that all QA tests complied with the tolerance limit. The detector efficiency for I-131 is within the range of 3.77% − 4.99% at 0 – 7 cm NCD. The MDA for I-131 is between 50.96 Bq to 129.90 Bq, which are comparable with other thyroid counter system in other institutions. The background radiation is maintained within 0.14 ± 0.01 cps. As a conclusion, the thyroid counter system is now fully operational and might be used for bioassay monitoring of potentially exposed workers to internal radiation as well as for the preparedness of response in the case of nuclear and radiological emergencies.

Abstract: Thermoluminescence (TL) is the phenomenon of light emission throughout heating of a material or substance that previously excited by ionizing radiation. The aim of this study is to characterize TL response that quantifies the linearity response over dose exposure. In this work, we investigated the TL response via thermoluminescence dosimetry (TLD) reader of commercial low-cost borosilicate microscope glass irradiated by 3 different radiation sources; electron, X-rays and gamma with dose ranging from 2 Gy up to 250 kGy. It has been shown that an indication of superior linear relationship TL-yield response with subjected to low dose from all radiation sources applied. Other TL fundamental dosimetric properties such as fading, reproducibility and sensitivity have also been investigated. It has been observed that the samples have not saturated at high dose kGy range in comparison to that of commercial TLD100 and telecommunication fibres of two different forms; Ge-B-doped PCF and Ge-B-doped FF. These appealing aspects have therefore prove that the low-cost microscope glass can be useful in wide radiation dosimetry applications e.g. medical, food sterilization, and oil and gas industry.

Abstract: NORMs refer to the term naturally occurring radioactive materials, occupying the entire environmental media, including water, air, living and non-living things, and the human body. The most abundant and common radionuclides exist in nature are two isotopes of Uranium that are 238

U and 235

U and Thorium 232

Th [1]. Accurate quantification of radioactive material uptake in the foodstuffs, exposure and distribution of radionuclides in a material is very important in respect of public health detriment. Herein, gamma-ray spectrometry is one of the most accepted and widely used techniques for the detection and analysis of radioactive materials for a wide range of activity [2]. Prior to measurement, the studied samples herein; soil, honey, soft drink, bauxite, dross and aluminium scraps, all these collected within Malaysia were kept in airtight condition at least for 6 weeks at room temperature to attain the secular equilibrium of the parent radionuclides and their respective daughters of

226Ra (

Developing Nuclear Fusion of the Stars and its Challenges

Oi Hoong CHIN

Abstract: In 1920, A. Eddington speculated that stars are powered by fusion of light elements. It was a little more than a decade later that M. Oliphant accomplished laboratory fusion of hydrogen isotopes and H. Bethe developed the theoretical basis of the main cycle of nuclear fusion in the following decade. It is now known that the stars are fuelled by proton-proton fusion, helium fusion, or the carbon cycle depending on their age and mass. In the case of our nearest star, the Sun which has core temperatures ~15´106 K, it is fuelled by the proton-proton cycle yielding 25 MeV of energy. The Sun is the primary source of energy for many forms of life on earth and will continue to be so for the next five billion years to come. It is little wonder that man dare to dream the impossible – to create a ‘sun in the jar’ as an alternative energy source to satiate mankind’s demand for energy that is largely dependent on fossil fuels which is predicted to deplete in 50-100 years’ time. This talk will discuss the ‘extreme’ conditions required to achieve nuclear fusion, the methods or configurations designed to meet these conditions and the challenges that must be overcome in order to realize the ‘impossible’ dream.

Determination of Thorium and Rare Earth Elements in Monazite

Cik Rohaida Che Hak, Sarimah Mahat & Ismail Mustapha

Abstract: Monazite is mineral obtained from ‘amang’ or also known as tin tailing. ‘Amang’ one time ago was left abandoned in ex-mining area. After ‘amang’ is known to have significant content of useful heavy minerals, and then it was processed stringently to produce monazite. To obtain monazite, ‘amang’ has to go through several stages of physical separation processes such as gravitational and magnetic separation. Nowadays, monazite is commercially available in Malaysia. In this study, monazite obtained from Perak’s ex-mining area was characterized using several techniques to determine the content of thorium and rare earth elements. The morphology of monazite was observed under stereoscope and field emission scanning electron microscope (FESEM). Whereas the chemical elements contained in monazite was determined using wavelength dispersive x-ray fluorescence spectrometer (WDXRF). Finally the radioactivity level of this mineral was measured using neutron activation analysis (NAA).

Abstract: Since 1980s, Neutron Activation Analysis (NAA) process has been setup in Malaysian Nuclear Agency (Nuklear Malaysia). Most of the procedures especially sample registration, sample changing and count; and sample calculation and analysis are performed manually. These manual procedures carried out by the NAA laboratory personnel are time consuming, prone to human error and inefficient. Hence, a system to automate these NAA procedures is developed. The developed system automation provides an effective method to replace redundant manual data entries, automate sample changing process and calculate sample analysis faster. This paper describes the design and development of system automation for NAA process called INAS which consists of three components of NAA procedures which are sample registration, counting and analysis. The system is developed under the IAEA/CRP project ‘Development of Process Automation in the Neutron Activation Analysis (NAA) Facility in Malaysia Nuclear Agency (RC17399)’.

Nurfarhana Ayuni Joha

Abstract: The 1MW PUSPATI TRIGA Reactor (RTP) which is the one and only research reactor in Malaysia was in operation since June 1982. It was controlled, monitored and protected using analog system. After almost 30 years of operation, due to ageing and obsolescence of components and equipment, RTP has planned significant modifications and upgrades to ensure the continuous safe and reliable reactor operation. Hence, Reactor Digital Instrumentation and Control System (ReDICS) project has been successfully completed in 2014. The ReDICS project was implemented on collaboration with Korea Atomic Energy Research Institute (KAERI) from designing until commissioning stage including Technology Transfer Programme (TTP). The old analog console was dismantled and reassembled as RTP Simulator at the Nuclear Reactor Simulator Lab for education and training purposes which means to be the first of its kind in Malaysia. Thus, this paper is means to share the experiences throughout the evolution of RTP instrumentation and control (I&C) system, as well as the status and future plans of ReDICS and RTP Simulator.

Irradiation Using γ-Ray Route to Synthesis of Silver Nanoparticles: Characterization and Antibacterial Evaluation

Salmah Moosa, Anis Nadia Mohd Faisol Mahadeven & Kamyar Shameli

Abstract: Aqueous dispersions of highly stable, silver nanoparticles (AgNPs) were synthesized using gamma ra diolysis with kaolinite as a stabilizer. A one-step silver kaolinite nanoparticles (Ag/Kln NPs) has been developed successfully by γ-irradiation technique in an aqueous system at room temperature and under ambient pressure. The use of this alternative method overcomes some unfavourable characteristics like long, tedious and costly process, uncontrolled size and distribution. The advantages of radiation processing of the materials relative to other methods are: no metallic catalyst is required, pure product; no oxidizing or reducing agent required, the process occurs at a liquid or/and solid-state condition, fast and inexpensive, environmentally friendly with controllable acquisition, and a good distribution with a controlled size as dose changed. The formation of nanosized silver kaolinite was confirmed by its characteristic surface plasmon absorption peak at around 415 - 425 nm in UV–vis spectra. The successful formation of Ag/Kln NPs has been confirmed by UV-visible spectroscopy, XRD, Transmission of Electron Microscopy (TEM) and FESEM-EDX analysis. The face-centred cubic (fcc) structure of the nanoparticles was evident from the XRD and TEM measurements. The TEM study showed the formation of Ag/Kln NPs have an average diameters of around 2.44 – 19.00 nm depending on the irradiation dose with spherical shape. The FESEM-EDX analysis confirmed the spherical shape of Ag-NPs on the surface of kaolinite and the element of Ag with the high purity. The effects of different experimental parameters, such as concentration of Ag+ and irradiation dose on nanoparticle formation were studied.

Post-irradiation Colour Stability of Pentacosa-10,12-diynoic acid-Functionalized Microsphere for Radiation Indicator

Naurah Mat Isa, Mohd Yusof Hamzah, Rohah Abdul Majid, Wan Aizan Wan Abdul Rahman & Mek Zah Salleh

Abstract: Liposomal structure of pentacosa-10,12-diynoic acid (PCDA) monomer in mobile phase is known to experience polymerization upon radiation absorption. The polymerized structure can be identified by a change of colour that is related to pi-conjugations and conformational changes. The colour change, however, is hampered by low colour reflection. Additionally, the colour change is also known to be unstable, contributing to unreliable data readings. This article discusses the effect of polymer core in PCDA against colour reflectance and its post-irradiation stability. White poly(styrene-co-butyl acrylate) (PSBA) microspheres were used as polymer cores that entrapped in the PCDA vesicles via hydrophobic-hydrophobic interaction. The ratio of PCDA volume layered on the core materials was varied as the following; 2:0, 2:0.5, 2:1, 2:1.5 and 2:2. The samples were then exposed to gamma irradiation ranging from 5 Gy to 50 kGy. Colour reflection of the samples were measured and reported as total colour difference (dE*) according to CIELab colour space. Result from the experiment shows that dE* of PCDA-functionalized PSBA were significantly higher (50% higher) compared to the control sample. Variation of colour at post-irradiation stage was also reduced to 4% for 50 kGy compared to 30% of the similar dose. The low colour variation was attributed to the presence of solid PSBA cores that hold the polymerized PCDA thus restricts its chain conformation, as well as its function in reflecting incident light.

Amy Hamijah Ab. Hamid

Abstract: The Malaysian Government in 2012, launched the Business Continuity Management System program initiated by the Malaysian Administrative Modernization and Management Planning Unit (MAMPU) referring to MAMPU.BPICT.700-4/2/11 (3) circular, which then in 2016, suggested being integrated with ISO 22301:2012 Standard and Business Continuity Good Practice Guidelines gradually. The proposed improvements acquired to further refine the government sector capability and capacity to gain a holistic organizational resilience in managing and sustaining their organizational survival countermeasures dealing with disruptive events. Unfortunately, there is a lacking of certified Business Continuity Management standard among the public sector agencies compared to local private sectors. Consequently, the Malaysian Nuclear Agency (Nuklear Malaysia) had been selected as one of the pioneering agencies to be certified accordingly. This selection prior to Nuklear Malaysia’s obligations towards radiological and nuclear safety and security within its operational facility management that refers to Act 304, Directive 20, International Atomic Energy Agency (IAEA) guidelines and many others. Hence, this paper recognized the suggested Nuklear Malaysia’s Business Continuity Management implementations and achievements using a case study approach. As a result, this paper benchmarked required literature reviews against the Nuklear Malaysia’s experience determining best practices in managing and implementing their organizational resilience apparently. As a conclusion, the resilient Business Continuity Management program needs to be incorporated with the agency’s capabilities to enable mitigation capacities and organizational survival of any unexpected disruptive events following through future challenges afterward.

Pyrolysis Process and Chemical Profile of Pyroligneous Acid and Biochar from Tambunan Bamboo

Nor Azwin Shukri, Shyful Azizi Abdul Rahman, Nor Azillah Fatimah Othman & Janni J.

Abstract: The purpose of this study was to investigate the effect of pyrolysis process of Tambunan bamboo on product yields of pyroligneous acid (PA) and bamboo bio-char (BC). Pyrolisis process produced BC, PA and tar simultaneously. Pyroligneous acid is generated through condensation of vapour released during pyrolysis process and bio-char is the charcoal residue produced during the same process. The maximum production of PA and BC was obtained at temperature of 450°C and 5 hours of reaction time. Chemical profiling of PA by GC-MS showed that Tambunan bamboo has a high content of phenolic compound which are known for antibacterial properties. Phenol, acetic acid and cresol were identified as the major constituents, while methylcatechol, ethylphenol and butanoic acid were minor constituents. It is suggested that phenols and organic acids are the active components for antibacterial activity and could serve as an alternative eco-friendly source of natural bio-pesticide for agriculture and wood preservatives. The BC were characterized by physical-chemical analysis in order to investigate the main changes caused by the pyrolysis process on their properties. Results revealed that BC had better combustion characteristic such as lower content of moisture and volatile content, and high calorific value (29.9 MJ/kg). The low ash content in bamboo-biochar (2.7% w/w) along with its relatively high content of fixed carbon (69.8% w/w) is associated with improved higher heating values (HHV). These results demonstrated that bamboo bio- char could be use as source of energy.

Neutron Irradiation Effect on Poly (Vinyledene Difluoride) - Lithium Bis (Oxalato) Borate Solid Polymer Electrolyte

Nurul ‘Adilla Heffny, Mayeen Uddin Khandaker & Abdul Karim Arof

Abstract: Following the growth of technological advancement, solid polymer electrolytes (SPEs) show a great potential to be used as active component in electrochemical devices due to their favorable physio-chemical properties. However, SPEs performance for practical applications is still not in expected level due to its low ionic conductivity. Fortunately, radiation treatment on polymer electrolytes has been emerged as an alternative to enhance its ionic conductivity as it is known to cause irreversible structural changes of the polymers. Neutron is a highly penetrating radiation that are known for its charge neutrality, thus it is becoming an interest to observe its non-coulombic effect on polymeric materials. Thus, in this study, a poly (vinyledene difluoride)-lithium bis (oxalato) borate film, prepared by using solution casting method, was irradiated using TRIGA PUSPATI Reactor facility of Malaysian Nuclear Agency at different time of exposure resulting in different neutron doses up to 155 kGy. The virgin and irradiated samples are characterized using X-ray Diffraction and Fourier Transform Infrared Spectroscopy to observe the structural changes in detail. The ionic conductivity of the polymer electrolytes was determined using Electrochemical Impedance Spectroscopy. It is expected that some structural changes would occur resulting in an increase of the ionic conductivity of the polymer electrolytes via neutron irradiation.
