Akrilamida

(Pengen naro di sini artikelnya hahaha... mengingat temenku, lagi nyari2 artikel tentang ini..) Hohoho... ada yang tau apa itu akrilamida sebelumnya?? Kalo blm, akrilamida ini adalah zat berbahaya dalam makanan yang digoreng, dibakar, dan dipanggang. Rumus kimianya C3H5NO... Mengingat kita kan setiap hari makan makanan yang digoreng, kita tetap harus jaga-jaga bukan...

Bagaimana bisa terbentuk akrilamida dalam makanan?
Akrilamida ini bisa terbentuk karena adanya reaksi Maillard, yaitu reaksi antara gula dalam makanan (contohnya glukosa, fruktosa, dan laktosa) dengan asparagin bebas (sejenis asam amino dalam makanan yang terbentuk karena reaksi pencoklatan). Asparagin ini bereaksi dengan gula pada temperatur tinggi (di atas 1.200° celsius). Biasanya peristiwa ini terjadi pada saat penggorengan, pemanggangan atau pembakaran. Ketiga proses inilah yang bertanggung jawab terhadap tinggi-rendahnya akrilamid dalam pangan. Semakin gelap warna produk akibat pemasakan, makin banyak kandungan akrilamida di dalamnya. 

Apakah dipakai di dalam industri?

Akrilamida, ujar Direktur Pusat Penelitian Tumbuhan Obat Universitas Nasional Dr Ernawati Sinaga MS Apt, adalah senyawa kimia yang biasa dipakai sebagai zat untuk menggumpalkan kotoran (flokulan) dalam proses pemurnian air, seperti untuk air minum atau pada PAM. Di luar negeri, umumnya air minum bagi kebutuhan warga kota dijernihkan dengan proses akrilamida. Senyawa yang mempunyai nama lain 2-propenamida, etilen karboksamida, akrilat amida, serta vinil amida ini juga dipakai di laboratorium untuk menganalisa protein dan makro-makro molekul. // Selain itu, juga digunakan dalam bahan baku perekat, tinta cetak, zat warna sintetik, zat penstabil emulsi, kertas, dan kosmetik.

Nah, sebenernya apa c bahayanya?

- Dalam jangka waktu lama, pada hewan uji coba, tikus, menunjukkan gejala genotoksik (memengaruhi gen) dan karsinogenik (dapat memicu kanker). Namun, pengaruh karsinogenik pada manusia belum teruji kebenarannya. Meskipun demikian, penelitian lanjutan tentang bahaya akrilamida pada manusia masih terus dilakukan.
- Akrilamida pada dosis tinggi terbukti menyebabkan kerusakan pada jaringan saraf dan mengganggu reproduksi.
- Bagi laki-laki, senyawa ini bisa menurunkan kesuburan. Sementara bagi ibu hamil yang termakan akrilamida, bayi yang dikandungnya berpotensi untuk lahir cacat (teratogen).

Nah, bisa diambil kesimpulan yaitu perbanyak makan sayur, buah-buahan, kurangi makanan yang digoreng-dipanggang-dibakar, beralih ke makanan yang dikukus atau direbus (seperti kue-kue tradisonal Indonesia, dimsum) hahaha.... Sama yang terakhir, kalau nge-goreng atau nge-bakar atau manggang makanan jangan sampai terlalu coklat..

Are You A Procrastinator?


What is procrastinator?
Procrastinator is people that doing procrastination....
In a nutshell, you procrastinate when you put off things that you should be focusing on right now, usually in favor of doing something that is more enjoyable or that you’re more comfortable doing.


How to Overcome Procrastination?

Step 1: Recognize That You're Procrastinating

If you're honest with yourself, you probably know when you're procrastinating. Here are some useful indicators that will help you know when you’re procrastinating:
  • Filling your day with low priority tasks from your To Do List.
  • Reading e-mails several times without starting work on them or deciding what you’re going to do with them.
  • Sitting down to start a high-priority task, and almost immediately going off to make a cup of coffee.
  • Leaving an item on your To Do list for a long time, even though you know it's important.
  • Regularly saying "Yes" to unimportant tasks that others ask you to do, and filling your time with these instead of getting on with the important tasks already on your list.
  • Waiting for the “right mood” or the “right time” to tackle the important task at hand.

Notes:
Putting off an unimportant task isn't necessarily procrastination: it may just be good prioritization! Putting off an important task for a short period because you’re feeling particularly tired isn’t necessarily procrastination either, so long as you don’t delay starting the task for more than a day or so, and this is only an occasional event. If you have a genuine good reason for rescheduling something important, then you’re not necessarily procrastinating. But if you’re simply “making an excuse” because you really just don’t want to do it, then you are.
In his 1986 article “At Last, My Research Article on Procrastination”, published in the Journal of Research on Personality, Lay noted that procrastinatory behavior is independent of need for achievement, energy, or self-esteem. In other words, you may be a procrastinator even if you’re confident in your own abilities, energetic, and enjoy achieving things.

















Why you procrastinate can depend on both you and the task. But it's important to understand which of the two is relevant in a given situation, so that you can select the best approach for overcoming your reluctance to get going.


Step 2: Work Out WHY You're Procrastinating

Reasons for procrastination are
- people find a particular job unpleasant, and try to avoid it because of that.
-another cause is that people are disorganized. Even if you’re organized, you can feel overwhelmed by the task. You may doubt that you have the skills or resources you think you need, so you seek comfort in doing tasks you know you're capable of completing. 
-surprisingly, perfectionists are often procrastinators, as they can tend to think "I don't have the right skills or resources to do this perfectly now, so I won't do it at all."
-one final major cause of procrastination is having underdeveloped decision-making skills. If you simply can’t decide what to do, you’re likely to put off taking action in case you do the wrong thing.

 

Step 3: Adopt Anti-Procrastination Strategies

These general tips will help motivate you to get moving:
  • Make up your own rewards. For example, promise yourself a piece of tasty flapjack at lunchtime if you've completed a certain task. And make sure you notice how good it feels to finish things!
  • Ask someone else to check up on you. Peer pressure works! This is the principle behind slimming and other self-help groups, and it is widely recognized as a highly effective approach.
  • Identify the unpleasant consequences of NOT doing the task.
  • Aim to “eat an elephant beetles” first thing, every day!

 If you're pocrastinating because you're disorganized, here's how to get organized!
  • Keep a To-Do list so that you can’t “conveniently” forget about unpleasant or overwhelming tasks.
  • Use an Urgent/Important Matrix to help prioritize your to-do list so that you can’t try to kid yourself that it would be acceptable to put off doing something on the grounds that it’s unimportant, or that you have many urgent things which ought to be done first when, in reality, you’re procrastinating.
  • Become a master of scheduling and project planning, so that you know when to start those all-important projects.
  • Set yourself time-bound goals: that way, you’ll have no time for procrastination!
  • Focus on one task at a time.  
 
If you're putting off starting a project because you find it overwhelming, you need to take a different approach. Here are some tips:
  • Break the project into a set of smaller, more manageable tasks. You may find it helpful to create an action plan.
  • Start with some quick, small tasks if you can, even if these aren't the logical first actions. You'll feel that you're achieving things, and so perhaps the whole project won't be so overwhelming after all.
If you’re procrastinating because you find the task unpleasant:
  • Many procrastinators overestimate the unpleasantness of a task. So give it a try! You may find that it’s not as bad as you thought!
  • Hold the unpleasant consequences of not doing the work at the front of your mind.
  • Reward yourself for doing the task.

Finally, if you’re procrastinating because you can’t decide what action to take, and are putting off making a decision because you’re nervous about making the wrong choice, see decision-making section. This teaches a range of powerful and effective decision-making techniques.
Remember: the longer you can spend without procrastinating, the greater your chances of breaking this destructive habit for good!
