From the cooperative learning activity, I learnt that as a engineer, we must inform the public or client about the project or product truthfully without hiding anything. Code of Professional Conduct state that a registered engineer shall issue public statements only in an objective and truthful manner. If not, our ignorant action will cause a negative effect to public or our client. As an example, we can refer to DC 10 Cargo Door case. This engineering failure caused a crash that killed all 346 people onboard. All 346 people had died just because the cargo had its door blown off at 10 000 feet. This disaster can be prevent if the responsible engineer inform about the serious design flaws at cargo door to the public or report it to the government. Even the engineers pressed the matter through normal channel to the highest level within both companies, but did not take it any further. If they are insists with their decision, maybe they can prevent this disaster.
                Another lesson that I learnt is we must be faithful and straightforward in our duties. We are prohibited to take any bribe from other parties. We also must prevent our self from involved in any situation that can lead to conflict of interest such as give a tender to our siblings company. For example, in DC 10 Cargo Door case, three inspectors at Long Beach plant certified that Ship 29 had been modified to fix the problem. We can safely assumed that the three inspectors had accepted bribes because each of then affixed a stamp to the Ship’s paper confirming the modification even in fact, the modification had not been made. If the inspectors be faithful and straightforward with their duties, they can prevent this disaster from happened.  
                I also learnt that the impact of engineering solutions on society. Every engineering solution has its own positive and negative effect to surrounding and also to us, human. General example of the impact of engineering solutions is using CFC’s as coolants. Even they had been chosen due to their excellent heat capacity but in the mean time they can cause destruction of the ozone layer. Another example of impact of engineering solutions is the nuclear power plant. The nuclear power plant is choosing as an alternative due to its low emission of carbon dioxide. However, in the mean time, it can be dangerous to us because if the leakage happens, the radiation will occur.  The poor engineering problem solving is maybe caused by poor at critical and independent thinking. Another reason is maybe because the engineer did not have enough knowledge about the engineering problem. Another reason is maybe the engineer is not experienced enough to deal with the problem. The solution to the poor engineering solutions is enhanced the engineer to improve their self by studying the case study that related. Another solution is the engineer must practice to think creatively and out of the box so that they can create creative solutions that will have zero negative effect to the environment.
                As a conclusion, this cooperative learning activity had give lots of benefits to me. From this activity, I learnt about major engineering failures that I had not known before. I also learnt the code of professional conduct as a engineer. These codes are very important to me in the future when I need to deal with the real engineering life. I also learnt that every engineering solution has its own positive and negative effect to surrounding and also to us, human.  I also learn how to cooperate with others in a short time.

Dear my sister Najihah, I wish you the best for your SPM;s results. Whatever the result is, never lose faith A good results in SPM  as the people said is the good start for a better future but frankly speaking, its NOT a good results will not guarantee a good future because what FUTURE hold for you is still a SECRET that keep by the ALMIGHTY
So, dear sister I wanna you to keep your head held high never compare the results with others whatever it is your result especially don't compare it among the siblings every one of us have their own hurdles and destiny
and a reminder to you my dear sister you already decide what is your path do not think about what others get try the best what exactly in front of you do the best but keep in mind try to live your life to the fullest STUDY HARD PLAY HARD
 and last but not least, remember always I will always support you you may think that I try to get you into something but I will always try my best to find something that I think is the most suitable for you so, I will always…


A Patient's Guide to Collateral Ligament Injuries Introduction The collateral ligaments are commonly injured parts of the knee. An injury to these ligaments usually involves a significant force, such as a fall while skiing or a direct impact to the side of the leg. This guide will help you understand where the collateral ligaments are locatedhow a collateral ligament injury causes problemshow doctors treat the condition Anatomy Where are the collateral ligaments, and what do they do? Ligaments are tough bands of tissue that connect the ends of bones together. There are two collateral ligaments, one on either side of the knee, that limit side to side motion of the knee. The medial collateral ligament (MCL) is found on the side of the knee closest to the other knee. The lateral collateral ligament (LCL) is found on the opposite side of the knee. Together, the collateral ligaments also work with the posterior cruciate ligament (PCL) to prevent excessive motion of the tibia posteriorly…


im officially 22 years old now i seriouslt did not know what to feel its not like during my ten years ago where im feeling excited to celebrate my birthday nowafay im not felt it anymore its felt like a normal day where i need to do my chores and also need to solve my life's problem
well then if i think back that I already 22 it make me realize there are lots of things that I need to do and need to accomplish if i make my mother as my benchmarking im still far away to get at a same level like her at least my mother when she's 22 she had found her other half means she already married with my father
meanwhile, im still nowhere im still finding the purpose of my life still try to rule out myself and im still far away from finding the other half of me
22 its like a magic number where ur think that u are big enough to make a big decision for ur life but u know deep in ur heart u still confused with ur choice
22  make me think harder than before lots of my friend already have their…


1.INTRODUCTION  Figure 1 : Optical Single Cylinder Engine Internal combustion (IC) performance is one of the important aspects in automotive industry. The higher the IC performance, the powerful the engine car to be, therefore cause the higher request between the lovers of high performance cars. However, engineers had faced lots of problem in the way to determine the exact and more accurate performance of IC engine. These problems happen due to lots of factor such as the material that IC engine made of from. The IC engine is made of from all-metal materials and this prevent engineers to gain a detailed insight of the mixing, combustion and emissions formation processes occurred in the cylinder of IC engine. Therefore, the Optical Engine has been introduced as the improvement to the original system. High-speed imaging combined with the optical access provided by a optical engine offer the ability to directly image and compare ignition and combustion phenomena of internal combustion engin…


Rindu itu hadir lagi
Entah untuk yang ke berapa kali
Hati terasa ingin tahu sekali
Apa khabar kamu yang tiba2 menyepi Walau acap kali
Aku pesan pada diri
Usah simpan rindu lagi
Namun hati terus berdegil Lalu aku biarkan sendiri
Biar rindu bertamu di hati
