Lilin Harapan

KISAH EMPAT LILIN

Ada empat lilin yang menyala dalam suatu kegelapan di sebuah kamar. Suasana begitu sunyi sehinggga terdengarlah percakapan mereka.

Lilin pertama berkata “aku adalah damai namun manusia tidak mampu menjagaku maka lebih abik aku mematikan diriku saja !”  Sediki t demi sedikit kemudian lilinitu padam.

Lilin kedua berkata, “aku adalah iman. Sayangnya aku tak berguna lagi. Manusia tak mengenalku lagi, untuk itulah tak ada gunanya lagi aku menyala.”  Begitu selesai bicara tiupan angin memadamkannya.

Dengan sedih lilin ketiga berkata “aku adalah cinta. Tak mampu lagi aku untuk tetap menyala, manusia tidak menganggapku berguna lagi. Mereka saling membenci, bahkan membenci mereka yang mencintainya.” Tanpa menungu waktu lama , maka matilah lilin ketiga.

Seorang anak masuk ke dalam kamar, dan melihat ketiga lilin telah padam, karena takut kegelapan gadis kecil  tersebut menangis dan berkata “apa yang terjadi ? kalian harus tetap menyala, aku takut kegelapan” :’(

Lalu dengan terharu lilin keempat berkata “jangan takut, jangan menangis selama aku masih ada dan menyala kita dapat menyalakan ketiga lilin lainnya. AKULAH HARAPAN”

Dengan mata bersinar, anak kecil tersebut mengambil lilin harapan dan menyalakan ketiga lilin yang lainnya.

“Dalam situasi yang sesulit apapun kita dapat menghidupkan kembali cinta, damai, dan iman dengan HARAPAN”

About National examination

Dear Mr. Paul....

Here I enclosed my dicusion text about “National Examination”.

Talking about national examination, I think  all of us knows that, because this topic is the most urgent one nowadays. National examination becomes the hot topic in most of discussions. National examination was the goverment’s program. In analiticaly the goverment, National examination should be implemented as the evaluation indicators to measure and improve national education standards.

Evaluation is very important to map the position of each learner, set the status, knowing the extent to which teaching has been reached, look for and find a way out. From this evaluation will have a report and description. There lies the importance of the National Exam. Data from National examination mapping is used as the achievement of government programs to improve education quality in every area across Indonesia.

But, I still disagree if  the value used as the determinant of graduation examination learners. Because , to measure a student ability is not only by her/his result of examination which we could see in number, but also the result of her/his another examination in education. As education is not just talking about result, it also about attitude, personality and so on. This evaluation is only able to be done by the teachers at school who know and meet them everyday.

One something else what make me disagree with the national examination is The Indonesian education sistem are not same in every area across Indonesia. So it will make standard education not same too in every area across Indonesia.

WHY I CHOOSE PSYCHOLOGY MAJOR AT UPH AS A STEPPING STONE MY CAREER

“Seek knowledge from birth until death comes to you” That words suggest and inspiring us to always read up, implied in is attend the lecture. Among a variety of majors at campus there are favorite majors who always become the first  choice for aspirant university student, among other things is “psychology”.

There is many possibility reason of people why they chose psychology majors for their chareer. That possibility be able because go with the stream with friends, parents order, confused with their choice,  only want to try, like read book about  psychology, or they think  if they chose psychology majors they can solve their problem and so on.

For me psychology majors is interisting majors from the others majors.

Why  I choose psychology majors ?

For me there are reason why I think psychology majors is interesting majors and why I chose psychology majors.

The first one, we know that psychology majors are the majors that discuss the human self, which means where there is human psychology that's where needed. This is the reason that makes psychology or a psychologist is needed in the society especially in the current era of globalization is very thick with the problems associated with a person's psychological state. In short I can say that the field work for a psychologist in the future will be very open.

Secondly, I really like to socialize with others. I think that majoring in psychology is very suitable for people like me who loved to socialize with other people, so this will allow me to further explore this psychology majors and will make me feel comfortable to live lectures.

The third one, I want to be able to explore the character of a person including steeped myself, so I was easier to get along and I can help the people around me to solve their problems.

Those are some of my reasons, why I choose psychology department. Even so not all psychology majors at all universities in Indonesia as good. Selecting the best psychology departments is a must for all prospective students, because that's where a student will be formed into a psychologist best.

So ? why I choose Psychology Major at UPH as a stepping stone for my career ?

We know that UPH is one of the best universities of Indonesia. I am convinced and believe that the UPH can make me as a person of superior and ready to compete in the world of work.

With complete facilities, the lecturers are professional, innovative curriculum, vantage point, as well as individual training career I am convinced and believe that the UPH can make me personally a superior and competitive.

Especially with the scholarships for those who lack a financial increasingly attracted me to continue his studies at UPH, so I can go to college without the burden is too expensive, because my parents are less able to pay for my college if it is too expensive.

I also heard from people who are around me, that UPH is a great university and enjoyable. It made me more confident and more interested to study at UPH, especially when hearing their experiences regarding the UPH.

If later on I might be accepted at UPH with 100% scholarship, I would feel very happy and very proud to be enrolled in one of the best universities in Indonesia.
My vision for the future is doing their best, provide the best and be the best. May the Lord Jesus always bless me  be the best psychologist. Amen.

TITIK BEKU LARUTAN

        Tujuan :Mengetahui pengaruh adanya zat terlarut terhadap titik beku larutan

        Alat      : -Tabung reaksi kecil (5 buah ) dan rak

                      -Termometer (-10 sampai -110 )

                      - Gelas kimia plastik 1 liter (1 buah )

                      -Pengaduk dan sendok

      Bahan : 1. Larutan CO(NH2)2 1m dan 2 m masing-masing 5 Ml

                2. Larutan NaOH 1 m dan 2 m masing-masing 5 Ml

                3.Es batu 2 kg

                4. Garam dapur kasar 500 gram

      Cara kerja :

1.     Buatlah campuran pendingin yang terdiri dari campuran es batu dan garam      dapur kasar  sebanyak 8 sendok di dalam gelas kimia plastik.

2.     Isikan 5 mL air aquades ke dalam tabung reaksi kecil

3.     Isikan ke dalam 4 tabung reaksi yang terpisah masing – masing  5 mL larutan urea 1 m,urea 2 m, NaOH 1m , dan NaOH 2 m

4.     Masukkan tabung tersebut ke dalam campuan pendingin. Biarkan sampai membeku (di tandai dengan air yang keruh )

5.     Bila sudah terjadi pembekuan, angkat dari campuran pendingin kemudian adiuk-aduk sampai sebagian mencair.

6.     Kemudian ukurlah suhunya dan masukkan ke dalam tabung pengamatan

Hasil pengamatan

Larutan	Konsentrasi  (m)	Titik Beku (˚C)	Penurunan titik beku (˚C)
CO(NH2)2	1	-3,0 ˚C	1- (-3) = 4 ˚C
CO(NH2)2	2	-4,0 ˚C	1- (-4) = 5 ˚C
NaOH	1	-6,0 ˚C	1- (-6) = 7 ˚C
NaOH	2	-8,0 ˚C	1- (-8) = 9 ˚C

Titik beku air  =1 ˚C

Pertanyaan :

1.     Bagaimana pengaruh zat terlarut terhadap titik beku larutan ?

2.     Bagaimana pengaruh konsentrasi terhadap titik beku larutan ?

3.     Perhatikan dan bandingkan titik beku larutan NaOH 1 m dan larutan Urea 1 m serta larutan NaOH dengan larutan Urea 2 m. Mengapa terjadi perbedaan ?

4.     Simpulan apa yang berpengaruh terhadap titik beku (sifat koligatif) larutan ?

Jawab :

1.       Menurut hasil pengamatan kami, pengaruh zat terlarut terhadap titik beku larutan adalah penurunan titik`beku dimana titik beku air murni lebih tinggi dibandingkan dengan titk didih larutan urea. Hal ini disebabkan karena molekul-molekul air pada air murni yang dibekukan bisa langsung membentuk kristal-kristal es dengan sesamanya karena di dalam air murni tersebut tidak ada zat lain yang menjadi penghalang bagi molekul-molekul air untuk membeku. Sedangkan dalam larutan urea yang merupakan campuran urea dan air, untuk mengkristal molekul-molekul urea akan saling berdekatan dengan molekul yang lainnya dan membentuk semacam lingkaran pertahanan sehingga air yang berada diantara molekul-molekul urea akan terperangkap di dalam lingkaran pertahanan tersebut.

2.       Pengaruh konsentrasi terhadap titik beku larutan adalah konsentrasi berbanding terbalik dengan titik beku larutan, artinya bahwa apabilah konsentrasi larutan kecil maka titik beku larutan tersebut besar, dan begitu pulah sebaliknya apabilah konsentrasi suatu larutan semakin besar maka titik bekunya semakin kecil.

3.       Titik beku larutan NaOH 1 m dan larutan urea 1 m serta larutan NaOH 2 m dengan larutan urea 2 m memiliki perbedaan karena hal ini disebabkan oleh jumlah partikel zat terlarut, apabilah jumlah partikel suatu zat lebih banyak maka titik bekunya semakin rendah dan apabilah jumlah partikel suatu zat sedikit maka titik bekunya semakin tinggi.

4.       Dari hasil pengamatan di atas, maka kami menarik kesimpulan bahwa faktor-faktor yang mempengaruhi titik beku adalah :

a.      Konsentrasi

     Semakin besar konsentrasi zat terlarut dalam suatu larutan, maka semakin rendah titik beku larutan tersebut, dan semakin rendah konsentrasi zat terlarut dalam suatu larutan maka titik beku larutan akan semakin tinggi.

b.     Jumlah partikel

     Semakin banyak jumlah partikel zat terlarut, titik beku semakin rendah dan semakin sedikit jumlah partikel maka titik beku semakin tinggi.
