[en] Several activities and programs that have been implemented by AKRAB Nuklear Malaysia have started in mid-2016 to 2019. The main annual activity of AKRAB NM is the AKRAB Talk Program where guest speakers are comprised of psychology officers and special guests according to the title and theme of the talk. The first AKRAB Talk Program is Civil Servants Excellent: Active Mind and Physical Through Psychological Approach in 2016 up to the Familiar Talk program entitled Emotional and Physical Challenges with the Disabled, Are you ready? In 2019. Welcome from Malaysian Nuclear citizens and participants from External agencies are very encouraging. Apart from introducing AKRAB functions to the staff of the Malaysian Nuclear Agency, it is also meet the requirements of the PSD as stipulated in circular No. 18 of 2005. (author)

[en] Gaharu oil extraction system developed by Nuclear Malaysia is a hydro-distillation system innovated from the tradition method and improvised with science and technology to enhance the process efficiency and safety. The main component of gaharu oil extraction system included the extraction vessel, condenser and collection decanter. Apart from the extraction unit, the gaharu oil extraction process also incorporated two major supporting systems. These systems are the liquefied petroleum gas (LPG) system and the water cooling system. The LPG system is solely used for heating the vessel, which contains a mixture of treated and grind gaharu bark and fluid, to produce steam. Meanwhile the water cooling system is used to supply the necessary cool water into the condenser unit and facilitate in the transformation of the mentioned steam into gaharu oil and distilled water. The dissipate water from this process will be channeled back into the water cooling ponds to let excess heat to be removed and allow the cool water to reuse again by the process. (author)

[en] Full-text: Communication skills are among the skills in leadership. The importance of communication to leadership is strongly emphasized by many scholars. Every human being who lives on this earth is always faced with a risk, no matter at home or at work, it is also in the competition that we have. If we fail to manage the risks well, it is a bad sign. Risk at work is often associated with activity in relation to the work done causing harm to an employee. When this risk is not controlled, it will trigger an accident at work. To prevent this accident, preventive measures should be taken at work. It is the responsibility of every employee and employer to ensure that the work environment is safe and healthy to generate more productive outcomes. (author)

[en] There are 27 institutions in Malaysia involved in research and development (R and D). They are categorised into three different groups; the universities, Government's research institutes and statutory body research institutions. The universities are governed by the University and University College Acts and are placed under the jurisdiction of the Ministry of Education. The statutory body research institutions exist under their respective Acts while Government research institutes are placed under various government departments

[en] Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to solve and analyze problems that involve fluid flows or hydrodynamics. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as combustion or mixing operation. Nuclear Malaysia has two (2) software which is ANSYS 13 and 19.2 for CFD applications. It is a general purpose software, used to simulate interactions of all disciplines of physics, structural, vibration, fluid dynamics, heat transfer and electromagnetic for engineers. This paper will show case the use of CFD in multiple applications in Nuclear Malaysia. Plant Assessment Technology (PAT/ BTI), Reactor, Wastec and e-TAG are among the potential users of CFD in Nuclear Malaysia. Its application in R&D has become stepping stone in going parallel with Fourth Industrial Revolution (FIR) in Malaysia. (author)

[en] The use of printer devices to print documents nowadays seems to be inevitable even though there are calls and campaigns run continuously related to reduce the printing of insignificant documents. This device is easy to find and easy to use, especially when in offices when consumers do not have to worry about the cost of paying electricity bills, the purchase of paper and ink or the cost of maintenance. Based on the review using the Asset Management Monitoring System (SPA) of the Government of Malaysia in this agency, the number of printers registered as capital property is 339 units while those registered as inventory are 59 units. A study on the use of printers in Nuclear Malaysia was conducted in February to May 2019 involving 22 buildings in the Bangi Complex and 17 buildings in the Jalan Dengkil Complex. Private printer information is also taken using the manual method which is physical inspection and found that the number of printers available in Nuclear Malaysia is more than has been registered. The data that has been collected is then analyzed, among others, to find out the total electricity consumption of each printer model to see the extent to which savings can be implemented in addition to the methods that can be done to optimize consumption. This paper also suggests some improvements in terms of printer management so that it can be used more effectively and optimally without affecting the daily routine of the department. (author)

[en] This paper describes the design of a window cooling system implementation for the new low energy electron beam (EB) accelerator installed at Block 43T, Nuclear Malaysia. The low energy EB is a locally designed and developed with a target energy of 300 keV. The heat coming from the beam energy is very high; therefore an appropriate cooling system is required to prevent the breaking of the very thin (μmm) titanium window which could avoid disruption the beam transportation inside the vacuum accelerating tube and breakdown of the high voltage equipment. Therefore, the new window cooling system is designed and fabricated to get the desired air cooling system to cool down the 9 kwatt (30 mA, 300 keV) beam power. The measurement of airflow distribution within electron accelerator window of this design is presented. (author)
