CBT in Indonesia, Needed or Forced?

Computer has been one of the greatest invention of all time. It has been used for many sectors of our life, including education. Lately, the Education minister of Indonesia, Anies Baswedan, confirmed that Indonesia would be having computer based national examination starting from 2015. Moreover, the minister of higher education has also developed a system to implement computer based national university entrance examinations. The ministry claimed that Indonesia’s education system and environment has surpassed the requirements to execute the overwhelmed computer baser tests. However, there are numerous facts showing that our country has not worked effectively in preparing the computer-based test. In addition, at least there are three major reasons why we have to postpone the implementation of computer-based tests in our education system.

First, it will take longer to execute the computer-based tests, so there are chances that students will do deceptions. Based on my experience, while executing the computer based tests, the invigilator will miss some tests regulation. The regulations that are frequently missed is students who open other programs while taking tests. This problem may have been fixed by the government, but there are chances that students nowadays are highly capable to manipulate the tests programs. They might have studied how to hack the examination test programs on computer by only searching on the internet. As an adult, we can use social medias to make an approach and motivation for students in order to avoid act of deceptions in exams. A short video created by Suli Breaks on youtube.com is a good start video which states that grades are not responsible for someone’s future and also criticizes on our education systems in order to embrace students and spark their spirit to try their best in exams.

Other reasons that supports why we are not ready to implement the system is that there are chances that computer-based tests can lead to leakage to examinations questions. Based on national examinations on 2015 experience, the problems served on the exams are available to the students who obtain the link on the internet. Moreover, this issue has been around on our education system since the first national exams was held. The government always suspects the company who is responsible for printing the examinations papers but now there are also chances that the companies who responsible for online examinations are involved. If the computer based examinations are executed nationally with this problems unresolved, how could the future computer based test go smoothly?

Despite the previous issues, the minister have said that schools in Indonesia have met the minimum requirements to do computer based test. The ministry also have stated that public government company will help the process to implement the system on schools. In fact, many schools, especially private schools, are not ready to implement the system. Most of the private schools, which are located in the east side of Indonesia have not met the requirements to do the tests because they have not sufficient number of computers, computer operators or even any other infrastructure that supports the education itself. Not only on the east side of Indonesia, there are also numerous schools on Java which have not gained an access to internet such as schools located on the hinterland of Java.

While having such a good progress on our education system, the government and we have to look closer into the problems’ details. We are not ready yet to execute the computer based examinations now. We have at least three major problems that make an obstacle to execute the tests, while advancing in technology is a must for our education system. As responsible adults, we have to keep our next generations who will support Indonesia in the future by working harder for our education system. While we are not working harder to achieve a better education system, computer based national examinations will be only our dream.

Optimizing Energy by Nanotechnology

Nanotechnology has become one of the popular topics studied by many researchers and scientists. By January 2015, researchers have discovered that nanomaterials have been one of the alternative ways to generate and boost the production of renewable energy. They also have discovered a new class of low cost material based on to become a catalyst in various process of energy production. Latest research also have paid an attention on how nanotechnology can build a durable yet cheap material for power plants around the world. These progressive inventions on nanotechnology are enabled by the fact that our world in 2050 will need to double its energy production in order to maintain the human’s life. Through this urgent reasons, nanomaterials have three advantageous ways and methods to optimize our energy demands.

One of the methods that can be easily used is by using materials based on nanotechnology to provide efficient energy storage. There are numerous examples on how nanomaterials can enhance the efficiency of the energy storage and one of them is batteries. Fortunately, researchers have gained an access to improve the ordinary lithium ion powered batteries which are found frequently on mobile electrical appliances by changing its electrode structure. Scientific results show that nanostructured electrodes have the ability to conserve the charge of energy better and have more flexibility compared to the old electrode bars.

Another alternative way would be by using nanotechnology to improve the process of the energy production itself. The optimization on energy production by using nanomaterials have been implemented on hydrogen powered fuel cells, wind power plants and PVs ¬- a device which converts solar energy to electrical energy by utilizing the photovoltaic effect. On hydrogen powered fuel cells, nanomaterials have shown a good performance of being a catalyst to speed up the reactions occurred. Rather than being a catalyst, nanomaterial on power plants and PVs are used to enhance their structure to become lighter yet stronger and more durable than before.

The outstanding materials derived from nanotechnology can also be used for enhancement of energy distribution around the world. Recent studies have shown a progress on optimization of wireless power transmissions that can be seen today on wireless charging used by recent smart phones. Researchers stated that future wireless power transmission can be transmitted by lasers, micro-waves or electromagnetic resonance by optimizing the components into a nano scale. In addition, high voltage transmission system had applied the nano filter for electrical isolation system and soft magnetic materials to achieve efficient current transmission.

In the end, nanotechnology have shown a quite good progress since it was first discovered on 1981. Yet, nanotechnology has given us access to maximize efficiency of energy by using nanomaterial as energy storage, improvement quality of energy production or even as the efficient energy distributor. Even though, the predictions stated by experts that the energy demands in the future will be overwhelmed are inevitable. Will nanotechnology be the answer to our future problems? Furthermore, are we going to survive from our own energy demands?

Snicket’s Chosen One

Three young children of Baudelaire met a series of serious unfortunate events after their house was burnt down completely. It was a gloomy afternoon in summer when they had to face the reality that besides their house was burnt down mysteriously, their parents were gone missing. Their unfortunate luck did not stop there. They had to move in with their long lost uncle, Count Olaf, who secretly was only aiming for Baudelaire’s family wealth. They also had to watch the dead of their relatives who were killed by Count Olaf and his fellows. After a long series of unhappy stories that the Baudelaire had, the reason was later known why they had to go through a tearful journey. It was caused by the confidential information that the family of Baudelaire had carried for years. Three young children of Baudelaire – Violet, Klaus and Sunny, had to hide it from Olaf because they knew that they are chosen to keep the secret safe for their family’s sake.

Who says size does matter?

You will only feel small when you are afraid.

Who would ever think that a green small pathetic creature can be one of the well-known villains in history? One percent of gas and ninety nine percent of evil, this creature is composed by. Being small is not a reason for him not to be a selfish, rude and cunning soul. Even more, his effort in attempting to steal Krabs’s overwhelming secret recipe of Krabby Patty, created together by this creature and Krabs back then, made the story of Spongebob Squarepants series really interesting. Plankton, the name of this creature, is derived from aquatic creature. He possesses many unique abilities, from his intelligence constructing an idea to take the secret recipe, camouflage into something outrages, to cursing the God of Water. Although, behind his magnificent intelligence, Plankton always be helped by his computer based wife, who is named W.I.F.E which stands for Wired Integrated Female Electroencephalograph. However, his absolute fate which is failing the plan that he had created holds his aim up.

Who is most responsible for this miserable character? Stephen Hillenburg who is the primary creator of Spongebob Squarepants serials, drives the character Plankton into a different average villain that we have ever known. Audience of the kids’ television serials usually accustomed to a bulky looking, mischief ideas or even super powered abilities which are granted to the villain. Yet, the good people in the serials usually have weak abilities or needed to be trained by almighty supervisor before battling with the villain. However, Plankton, the antihero in this serial, has another story to talk about. The atmosphere generated from the whole series brings the audience to believe that even though you have a weaknesses, if there is a will, there is a way. In this case, Plankton, knowing that he is seen to be a hyper small creature, has a huge will which is acquiring the secret recipe and it supports him to show his best.

I believe that many people do not see this side of Plankton. Hillenburg has successfully tricked the crowd to minimize the character of Plankton, turn and look him down. On the other hand, Plankton’s hard work is undeniably true. He is the one who knows his flaws and he knows how to fix them. He realizes that he may not be able to trick Mr. Krabs who fouls in many odds and has many experience in manipulating money, so he invented W.I.F.E to be his ideas generator. He also knows that with his bite-sized body, he would not be able to steal away the recipe, thus he designed many disguised. Size really does not matter to him.

It is true that the way he seeks for a success life is not the way it should be, but the efforts and defeats he has made push him harder even more. Focusing on deciding which side is Plankton would be, most of the people will choose Plankton as the major villain in the serial. However, after all of the facts stating his remarkable spirit and efforts conquering his fears, I would sort Plankton as the best villain ever on kid’s television shows in history.

My First Post!

In fact, this is not the first post in this blog, but I need to post something, some kind of greeting post. At the first sight, I know this greeting post sounds lame, boring, unsatisfying, or even worse unable to be graded.  Actually, this post was my experiment and a chance to study a lot about how blogs.itb.ac.id works. I have known that this blog is supported by WordPress, but since I have not used WordPress before, I have to practice more especially about widgets and the decorating stuffs. I used blogger instead of WordPress because blogger is very easy to handle with. In blogger, I would change the HTML code. However, I have not figured out where the codes are written until now. Hopefully, it is written in HTML, not CSS.

While writing this post, I am waiting for some videos on youtube buffered. It is about cooking tough, but I find it interesting and tasty. Maybe, you can try this at home and please comment below so I know what’s your opinion about my blog – also you can comment about the video. Thanks!
