must read fabel… (buffalo, farmer boy and the tiger)

Friday, June 15th, 2007

Once upon a time, there is a farmer boy who have a buffalo. This buffalo is very obedient, it follows wherever the farmer boy goes.
Every morning the farmer boy always bring his buffalo to the farm whether they have a job are not. When they don’t have any job,
the farmer boy often bring the buffalo to the savana near the village. There’s a large green grass moor, and the buffalo can eat it freely
while the farmer boy play around the field and have a good time with the other boy.

And then… suddenly, when the buffalo are lonely there’s a tiger come close to the buffalo and the tiger said,
Tiger             : "I’ve been watching you for several day… You are always brought by the farmer boy to this place and you always comply him. I was wondering, why are you always comply him? Because if I compare that human (farmer boy) with you, he is very little than you. Why don’t you attack him with your horn… ? I’m sure he’ll lose or die. And then you will free just like me, free to go wherever you wanna go."

And then the buffalo answer it,
Buffalo    : "Actually I’m very afraid of him"   

With the mocking face the tiger said,
Tiger    : " Ha ha ha… you’re so Dumb Ass, Your body is big, but you don’t have a courage to fight with a little boy… Idiot!!"

The buffalo answer it again,
Buffalo    : " I’m sure you’ll also afraid with him, if you know the humans strength"

The tiger are angered with the buffalo statement, and curious about what kind of strength is it. To satisfy his curiousity the Tiger asked,
Tiger    : " What kind of strength that the human have…that makes you afraid with him?"

………………………………… after a while…………….the farmer boy come to that savana……………………….

Without courtesy, the tiger asked the farmer boy
Tiger    : "Hey Little child… what is your strength?, so this Dumb Ass buffalo afraid of you… "

And then the farmer boy answer it,
Boy    : "As a human, God Gives me a strength that doesn’t given to the other creature, i.e. intelligence (akal)"

Tiger     : "What is Intelligence, can I see your intelligence? If you don’t show it to me, I’ll eat you!! * the tiger asked the boy and intimidate him.

With calm, the boy answer Tiger’s question,
Boy    : " Hmm.. I can’t show it… because I left my intelligence at my home"

suddenly the Tiger answer it,
Tiger    : " If that so, you can take it first…!! " * the tiger try to push the boy to take it…

Boy    : " Actually I can bring it to you from my home now, but it’s useless… you’ll certainly run if you see it." (the boy don’t wanna loose in conversation….)

The tiger answer it boastfully…
TIger    : " I won’t run!!!.. I promise…!! " * the tiger is very confident

Boy    : " Hmmm… how about I tie you on the tree first… so you can’t run"  * the farmer boy answer it…

Tiger    : " Oke!! I agree… you can tie me!!"

………………………………….suddenly, that farmer boy tie the tiger tightly to the tree. …and then the tiger not only can’t run…but also difficult to breathe and move…….
after he has finished tie the tiger……………….that boy away…. back to his house…………………

The buffalo watch the whole event………….and suddenly the buffalo laugh to the tiger……..

and said "Now what can you do??"…………….
and the Tiger can’t answer the question, he panic and struggle to get loose from the tie……

and then… the buffalo wisely said…
"That’s the human’s Intelligence… heu heu heu…." * the buffalo said it while he go follow his master (the farmer boy)

smile’s meanings

Thursday, June 7th, 2007

no need cost, but could have a lot and wide meaning

enriches the donees, without lays poverty to whom give

just awhile, but sometimes gives impression and memory which could never forget

no one who’ll feel richer or poor without it, they’ll just feel rich with it means

could grow the happiness in house, maintain the good relationships in business
and seal the amity

dismisses tire for everybody exhaustion

brightness for worry

comforter for anguish

the best and natural bidder for who in hardness

can’t be bought, bet, borrowed, and stolen

personal property until it’s thrown

nobody who very need it, until it couldn’t be given

and if somebody (maybe) is tired to give it, why don’t we leave it a little bit
for him/her :P

and the most important is…
smile is worship…(hadeeth : Abu Dzar radhiyallahu ‘anhu)
which give the bless for anybody who undertake it…

sudden inspection T_T

Tuesday, June 5th, 2007

Yesterday, 12 AM.

I was playing guitar and sang a song in my lovely lab…lonely, because the other assistants were praying at the Masjid . With my discordant voice, I tried to entertain my self ^_^.
but…
In the middle of my song, there was a person knocked at the lab’s door… "knock knock knock…!!"

Mean while, I was wearing my headphone and in full concentration with "Peterpan’s song" at that time.
And after several time, I am very surprised…!! because Mr. Jangkung Rahardjo (Chairman of Electrical Engineering STT Telkom) is already in front of me. Not just that, behind him, there were Mr. Burhanuddin (Chairman of Electrical Diplomma Program), Mrs. Sofie (Secretary of Electrical Engineering), Mr. Iwan Iwut (Chairman of Signal Processing Laboratory)

I was very shocked at that time, because I just wore my "Dagadu" clothes, and a guitar in my hand. Reflexly, I put off my guitar and made some salutation with them.
And then…  we had some conversation at that time (in Javanese.. because Me, Mr.Jangkung, and Mr.Burhan were Javanese :P):

Me     : (with startled expression) "ehh.. Pak Jangkung, Sugeng Siang Pak!, wonten menopo pak…kadingaren tindak dhumateng mriki…?",… mean while my eyes were weeped around the room and saw the other Lecturer T_T…made me more nervous..hikz…

Mr. Jangkung : "Selamat Siang Dhek, orak ono opo2 kok dhek…mung pengin niliki Labmu.."…when Mr.Jangkung answered my question, I made salutation with Mr. Burhan and the other… :P

…….they entered my lab and looked around the room…….

Mrs. Sofie said, "Kok di sini panas yah…??"
and I answered that question : "Maaf Bu, AC-nya di matikan, soalnya AC sentral…kalo di hidupin terus kita bisa kedinginan …n’ gemeteran :P "

Mr.Jangkung said : "Opo gak isho di setel suhune tho?"

Me : "Boten saged Pak…" (in my heart…I spoke with my self…hopefully we get some new Air Conditioner..hehehe…)

Mr.Burhan spoke to Mr. Jangkung : " Yo gak isho tho Pak, wong AC sentral… Suhune yo standar sentral…" … I just smiled when I heard Mr. Burhan’s answer…

…………and then Mr. Jangkung continued his inspection…….till behind MSC, where the Mattresses weren’t  packed yet…..and scattered around Y_Y………. (Damn!!!…why the last woke up person didn’t packed it… hehehe… the last person = it was ME!! :nohope: )
and then…………

Mr. Jangkung said, "Iki kasure nek awan mbok diringkesi…onok kasur rak popo…neng ojo nganti kethok teng slengkrah koyo ngene…"

and I answered that question : "biasanipun kita simpen teng wingking lemari kok pak" (while my hand pointed at some places behind the cabinet… T_T)

and then Mr.Jangkung continued his investigation…his eyes were looked around…and counting for something… "Wahhh… Lha wong kasure onok Papat…Piye ngumpetkene?? "

and I just can made a sour smile T_T, :speechlesshhh:… lol

and the conversation continued…
Mr.Jangkung: "Besok Kira2 tanggal 21 Juni, ada kunjungan dari S2 UI…kalian persiapkan ya…apa apa yang mau di tampilkan..!!"

Me : "Nggih pak…mangke kami persiapkan Aplikasi2 yang telah kami hasilkan… termasuk Location Based Service, dan Mobile Remote Desktop..ingkang menang Indonesian Mobile communication Competition kemarin…yang di adain Excelcommindo Surabaya :P…terus software2 planning ma Optimasi Cellular pak "

……………at that time, I hoped that they wouldn’t took a long time inspecting my lab….T_T….
but… they sited down on the chair.. and asked me more question…. T_T

Mr.Burhan : "Sentral iki jek ishoh diuripke rak??"….he looked at the MSC AMPS…
"sesuk diresiki ya…mosok sentral kok onok sawange ngene…"

Me :"Sebenarnya sentral ini masih bisa di hidupkan, hanya terdapat masalah pada loadsharingnya (kalau nda salah… :P), tapi…. ini kan MSC generasi pertama…jaringannya sudah tidak ada Pak"….Mr.Burhan nods his head… and then shake it…

and then Mr.Burhan Said : "Mungkin perlu di ganti Sentral baru ni Pak…"…he’s talking to Mr.Jangkung….

Me : "Sebenarnya, kita sudah pernah mengajukan permohonan sentral CDMA IS-95, ke Divre V Surabaya…Alhamdulillah sudah disetujui, tinggal di bawa saja..namun, saat ingin dibawa kemari…biayanya cukup mahal, ditambah lagi biaya instalasi… dan STT tidak menyanggupi biaya tersebut T_T "…..

………at that time, I was wondering….would Mr. Jangkung conscious with my point……

and then Mr.Jangkung said: "Actually, we have signed an MOU with Telkomsel, maybe We could arrange it with Telkomsel…^_^" ….hehehe….capek saia nulis basa Indo.. (lha..iki nulis Indo tho??)

Me answered : "hmm… a few weeks ago, Mr.Nahwan and gsm crew…had created a proposal to Telkomsel, in order to made a Telkomsel research center in mobile comm. Laboratory STT Telkom…hopefully, it could be achieved "

………………..and the next conversation was very shameful………………. T_T

I saw… Mr. Jangkung looked around a corner (forbidden corner… :P) with a cabinet that full contained "gsm crews" vestiture…………. and then…Mr.Jangkung said:

Mr.Jangkung : "Iku sempake sopo.. kok kethok melok-melok ngono…" (Damn!!! I forgot to closed the cabinets door… Y_Y…and) "pantes… bu sofie dari tadi liat ke situ terus…" LOL…..

Me : Reflexly…I ran to that corner….and closed the cabinets door while saying "di tutup…ditutup…ben rak kethok….Y_Y…pakaiannya anak2 pak :P…" ::….shame of me::

Mrs.Sofie said, "Oke then… I’ll arange a program called ‘jumat bersih’, maybe in the nearby time…I’ll make a letter…to the whole Elctrical Labs…so we can clean E building together….assistants..and lecturers"………hiks…..

* Now the letter is on my table… hehehe….

after that… they were away from my lab….towards to the other labs…
and leave Big shamefulness to me!!!
I wondered… was there any ominous person…. just like me… Y_Y

hahahaha…..
just took the "hikmah"…. and learned to be better… :P

hopefully useful….

minilink Ericsson 4-MMU Installation and Measurement

Friday, June 1st, 2007

Yesterday, I’ve experienced in Ericsson Minilink Installation.

For Introduction, maybe I want to give briefly explanation about this things. Minilink is a kind of antenna, which is produced by Ericsson. Ericsson’s Minilink 4-MMU, have a capacity up to 4 E1. It means the total traffic that can be carried by this device is about 4 x 2.048 Mbps. This device is used to connect between two Network Element in Mobile Communication System such as BTS to BTS. It operate in 7GHz frequency, with the diameter 0.6m, Gain=7dB, with maximum hoop=12 km.

This is the shape of Ericsson’s Minilink.
310507_1351
310507_1354

The installation process consists of several steps and tests:

1. We have to install Minilink antenna according to the site planning. In one hoop, we need 2 antenna to build a Transmission link. So there are two site (tower) have to be installed with this antenna. In the picture below, you can see that the antenna is kind of radome antenna with mounted RAU (power amplifier). After we have installed the antenna, then we have to connect the cable on it.
310507_1350

2. Connect the cable (from antenna) to the MMU (modem) in door unit. It’s kind of
modem which can transfer up to 8 Mbps. (4 E1). MMU has several ports, choose the coax port:
310507_1334

3. Connect the MMU to the power supply. Caution: "we have to make sure the voltage phase, in order not to be reversed"
310507_1333

4. Configure the site name, frequency carrier (Tx and Rx), power transmit, and sensitivity from the software interface. Note that this whole process (1 - 4) is done on the both site.
310507_1337

5. After both site have been configured and UP. Now we can check and set the azimuth and elevation of the antenna, in order to get good clearance factor and the best power receive.  We can monitor the receive power from software interface.
310507_1407

6. We can also measure the voltage (power) level directly on the antenna using AVO meter.
310507_1408

7. After the optimum power transmit and receive have been obtained, we can do Bit Error Rate test using BER meter. BER test can be done on one site, but we have to loop back MMU traffic in the other site (see the picture below). So we get the actual traffic that we have to measure.
310507_1359

if the BER Transmission requirement is about 10^(-8), and the equipment capacity is 8.192 Mbps. Then we have to measure it for at least, 12.5 second in order to achieve the correct measurement.  Longer we measure, then better measurement can be achieved.310507_1508

8. After we have checked the BER performance, the Transmission link is ready to be used. ^_^

Thanks… hopefully useful.
