We finished watching "Good Night, and Good Luck" today in class. This film explores a lot of issues that are relevant to today. I found this short video on YouTube that spliced together Edward R. Murrow's speech that appears at the beginning of the film and continues at the end of the film.

We continued our look at the Vietnam War today by watching an excerpt from "Born of the Fourth of July". Please remember that you have your Cold War Concepts Quiz tomorrow, please see the study guide here. Here is a link to the NPR that explains the story behind this photograph, definitely worth the time to read or listen to the podcast, and make sure that you look at the photo gallery of Eddie Adams' photographs of the Vietnam War.



There are certain iconic images associated with the Vietnam War. Here is another:

The above photograph is of Phan Thị Kim Phúc, O.Ont (born in 1963), she is a Vietnamese-Canadian best known as the child subject of a Pulitzer Prize winning photograph taken during the Vietnam War on June 8, 1972. The iconic photo taken in Trang Bang by AP photographer Nick Ut shows her at about age nine running naked on the street after being severely burned on her back by a South Vietnamese napalm attack. Contrary to popular myth, the US Air Force were not involved in the attack, and only two US troops were within 60 miles (97 km) of the scene, neither of whom had any say in the bombings. Still, it is a powerful image associated with the war.

Please remember to hand in your Southeast Asia package tomorrow as well as your Chapter 7 Key Terms and Questions. Your Vietnam War Assignment is due on Wednesday.

Cara Aman Ganti Aki Mobil Sendiri


Jangan pernah menggangap remeh ganti accu (aki) mobil. Terlihat memang sederhana sekali, cuma melapaskan pengikat pada kedua kepala aki (kutub) dengan mengendurkan bautnya. Bukan tidak mungkin, saat melakukan penggantian terjadi kesalahan atau kecerobohan. Akibatnya, merusak sistem kelistrikan bahkan electronic control unit (ECU).
Sebelum melakukan penggantian aki sebisa mungkin dilakukan pengecekan apakah aki tersebut memang betul-betul sudah rusak dan dalam mengganti accu (aki) usahakan ukuran dan kapasitasnya sama dengan standarnya. Kemudian perhatikan posisi kutubnya. Sepele memang, tapi berpotensi merusak komponen kelistrikan dan ECU, terutama jika salah pasang. Jika sampai salah pasang, dalam hitungnan detik bisa membuat beberapa komponen kelistrikan jebol dan ECU akan ngeblok.

Berikut ini langkah penggantian aki yang benar:
1. Pastikan kunci kontak sudah diposisi "OFF" atau tercabut. Setelah itu, diamkan sejenak untuk memastikan komponen kelistrikan benar-benar mati. Selain itu, agar ECU tidak aktif untuk menghindari hang atau kerusakan pada ECU. Jika kunci kontak masih "ON", masih terdapat arus listrik dan ketika kabel aki dicabut dapat berpotensi menimbulkan percikan api.
2. Untuk amannya, lepaskan kabel negatif dulu, baru setelah itu yang positif. langkah ini, untuk mencegah terjadinya percikan api. Ketika memasang kembali kabel (setelah diganti aki baru), lakukan kebalikannya. Jadi, kabel plus dulu dipasang, baru negatifnya.
3. Pada beberapa mobil perlu melakukan reset ECU setelah melakukan penggantian aki. Terutama untuk mobil buatan Eropa. Tandanya ECU perlu direset seperti takometer ngaco, power window dan central lock tak berfungsi dan indikator cek engine akan menyala.

We watched a couple of videos today from the BBC 20th Century History series: "The Road to Berlin" which explored the end of WWII in Europe, and "Cold War Confrontation" which looked at the division of Germany, the Berlin Airlift and the Korean War. I gave you a timeline of key events in the Cold War that you must memorize. I also gave you a Cold War Events package that included a chart of key events in the Cold War and associated key concepts of the Cold War that must be completed using a supplementary book that you had some access to today. Tomorrow we will be looking at the Korean War in greater detail, and then you will have some more time to work on your Cold War Events notes.

I would like you to go to the World War II Behind Closed Doors website tonight, and read the sections on the Yalta Conference and the Potsdam Conference. This is an excellent site, with tons of information, maps, video clips, timelines and archival footage and re-enactments as well. You do need to really make sure that you understand the Yalta Agreements and the Potsdam Declaration (among other things) and this is a great site to do this. Episode 3 is the one that contains most of the information that you would need to read and watch. There's a great little video clip on this website called "Stalin's Distrust of the West" that might help you see WWII from the Soviet perspective and why the Soviets might wish to extend control over Eastern Europe and be so distrustful of their wartime allies. You can find this video clip in Episode 3 (Dividing the World), scroll down and click on the video clip on the right called "Stalin's Distrust of the West". It's a short little clip, but you'll get the idea. We'll continue our look at the Cold War tomorrow.



We watched a video today on the development of the atomic bomb from the "History's Turning Points" series. After watching the video you were to copy down the notes that I had written on the board based on the topics covered in the video. If you missed today's class, you'll have to get these notes from a classmate. We then started a film study of the HBO documentary "White Light/Black Rain". We will finish this video off tomorrow.

We started our examination of the Cold War today. I hope that you read Chapter 7 prior to today's class. If you haven't read it yet, please do so tonight. I delivered a PowerPoint presentation today called "The Origins of the Cold War", which I have already sent to you. Make sure that you read the other handouts that I gave you on the Cold War today. I know that I gave them out at the end of the period, but they are important. The handout that covers the WWII conferences and agreements is especially valuable in my opinion. I would like you to go to the World War II Behind Closed Doors website tonight, and read the sections on the Yalta Conference and the Potsdam Conference. This is an excellent site, with tons of information, maps, video clips, timelines and archival footage and re-enactments as well.

It's a short little clip, but you'll get the idea. We'll continue our look at the Cold War tomorrow.



We watched some excerpts today from "Schindler's List" to help illustrate life in the ghetto and the concentration camps. We also started talking about the aftermath of WWII in Europe and the trial of Nazi war criminals at Nuremberg. We watched a short video on the war crimes trials at Nuremberg and I also gave you a handout with all the defendants and the results of the trial. Tomorrow, we'll be moving on to look at the end of WWII in the Pacific.

Tap Changer (Perubah Tap) Pada Transformator

Tap changer adalah alat perubah perbandingan transformasi untuk mendapatkan tegangan operasi sekunder yang lebih baik (diinginkan) dari tegangan jaringan / primer yang berubah-ubah.

Untuk memenuhi kualitas tegangan pelayanan sesuai kebutuhan konsumen (PLN Distribusi), tegangan keluaran (sekunder) transformator harus dapat dirubah sesuai keinginan. Untuk memenuhi hal tersebut, maka pada salah satu atau pada kedua sisi belitan transformator dibuat tap (penyadap) untuk merubah perbandingan transformasi (rasio) trafo.

Ada dua cara kerja tap changer:
1. Mengubah tap dalam keadaan trafo tanpa beban. Tap changer yang hanya bisa beroperasi untuk memindahkan tap transformator dalam keadaan transformator tidak berbeban, disebut “Off Load Tap Changer” dan hanya dapat dioperasikan manual (Gambar 1).

2. Mengubah tap dalam keadaan trafo berbeban. Tap changer yang dapat beroperasi untuk memindahkan tap transformator, dalam keadaan transformator berbeban, disebut “On Load Tap Changer (OLTC)” dan dapat dioperasikan secara manual atau otomatis (Gambar 2).

Transformator yang terpasang di gardu induk pada umumnya menggunakan tap changer yang dapat dioperasikan dalam keadaan trafo berbeban dan dipasang di sisi primer. Sedangkan transformator penaik tegangan di pembangkit atau pada trafo kapasitas kecil, umumnya menggunakan tap changer yang dioperasikan hanya pada saat trafo tenaga tanpa beban.

OLTC terdiri dari :
1. Selector Switch
2. diverter switch
3. transisi resistor

Untuk mengisolasi dari bodi trafo (tanah) dan meredam panas pada saat proses perpindahan tap, maka OLTC direndam di dalam minyak isolasi yang biasanya terpisah dengan minyak isolasi utama trafo (ada beberapa trafo yang compartemennya menjadi satu dengan main tank).

Karena pada proses perpindahan hubungan tap di dalam minyak terjadi fenomena elektris, mekanis, kimia dan panas, maka minyak isolasi OLTC kualitasnya akan cepat menurun. tergantung dari jumlah kerjanya dan adanya kelainan di dalam OLTC.

Proses Terjadinya Busur Api Pada Circuit Breaker

Pada waktu pemutusan atau penghubungan suatu rangkaian sistem tenaga listrik maka pada PMT (circuit breaker) akan terjadi busur api, hal tersebut terjadi karena pada saat kontak PMT dipisahkan , beda potensial diantara kontak akan menimbulkan medan elektrik diantara kontak tersebut, seperti ditunjukkan pada gambar dibawah.

Arus yang sebelumnya mengalir pada kontak akan memanaskan kontak dan menghasilkan emisi thermis pada permukaan kontak. Sedangkan medan elektrik menimbulkan emisi medan tinggi pada kontak katoda (K). Kedua emisi ini menghasilkan elektron bebas yang sangat banyak dan bergerak menuju kontak anoda (A). Elektron-elektron ini membentur molekul netral media isolasi dikawasan positif, benturan-benturan ini akan menimbulkan proses ionisasi. Dengan demikian, jumlah elektron bebas yang menuju anoda akan semakin bertambah dan muncul ion positif hasil ionisasi yang bergerak menuju katoda, perpindahan elektron bebas ke anoda menimbulkan arus dan memanaskan kontak anoda.

Ion positif yang tiba di kontak katoda akan menimbulkan dua efek yang berbeda. Jika kontak terbuat dari bahan yang titik leburnya tinggi, misalnya tungsten atau karbon, maka ion positif akan akan menimbulkan pemanasan di katoda. Akibatnya, emisi thermis semakin meningkat. Jika kontak terbuat dari bahan yang titik leburnya rendah, misal tembaga, ion positif akan menimbulkan emisi medan tinggi. Hasil emisi thermis ini dan emisi medan tinggi akan melanggengkan proses ionisasi, sehingga perpindahan muatan antar kontak terus berlangsung dan inilah yang disebut busur api.



Untuk memadamkan busur api tersebut perlu dilakukan usaha-usaha yang dapat menimbulkan proses deionisasi, antara lain dengan cara sebagai berikut:

1. Meniupkan udara ke sela kontak, sehingga partikel-partikel hasil ionisai dijauhkan dari sela kontak.
2. Menyemburkan minyak isolasi kebusur api untuk memberi peluang yang lebih besar bagi proses rekombinasi.
3. Memotong busur api dengan tabir isolasi atau tabir logam, sehingga memberi peluang yang lebih besar bagi proses rekombinasi.
4. Membuat medium pemisah kontak dari gas elektronegatif, sehingga elektron-elektron bebas tertangkap oleh molekul netral gas tersebut.

Jika pengurangan partikel bermuatan karena proses deionisasi lebih banyak daripada penambahan muatan karena proses ionisasi, maka busur api akan padam. Ketika busur api padam, di sela kontak akan tetap ada terpaan medan elektrik. Jika suatu saat terjadi terpaan medan elektrik yang lebih besar daripada kekuatan dielektrik media isolasi kontak, maka busur api akan terjadi lagi.
