Because I Can



How can I said that I suck?



Matthews is so stupid he can't even get a shot right.



Agreed. I suck.

Matthews Sucks



Why? Because Matthews sucks!

Take-Over Projects

Mungkin aku akan bercerita tentang salah satu project di mana aku pernah terlibat di dalamnya. Saat itu, sebuah menara telekomunikasi milik sebuah perusahaan besar mengalami stagnasi dalam pekerjaan konstruksinya. Entah kenapa perusahaan yang pertama kali menjadi pelaksana pekerjaan tersebut berhenti dan meninggalkan keadaan lokasi dalam kondisi seperti ini:



(sudut belakang shelter BTS operator)



(sisi belakang situs)



(kondisi dalam situs dilihat dari sudut kiri depan)



(kondisi dalam situs dilihat dari depan)



(situs tampak depan)



(menara telekomunikasi yang telah dicat)


Jadi, kami deploy tim sipil untuk pengerjaan pemasangan pagar dan outdoor grounding dan tim instalasi M/E untuk keperluan indoor shelter operator. Termasuk juga pemasangan AC unit dan alarm pagar.



(instalasi mekanikal elektrikal outdoor shelter BTS operator)


Tentu saja, karena saat itu pekerjaan masih bertahap -- dengan konsentrasi mengejar target RFI -- jadinya pagar situs belum dicat.

(situs tampak depan saat pagar belum dicat)

Kemudian tentu saja finishing pagar dengan penggunaan cat sesuai spesifikasi, yaitu Dulux Weathershield.



(pengecatan tembok pagar)


Dan tidak lupa, semua menara telekomunikasi dan struktur bangunan tinggi harus ditanahkan dengan sebaik-baiknya.

Untuk itu memang lazimnya digunakan material pentanahan (grounding) dari bahan tembaga -- yang sialnya justru kemudian menjadi incaran para pencuri karena harga jual per kilogramnya yang cukup tinggi. Tapi tentu saja spesifikasi harus diikuti karena faktor keamanan perangkat dan struktur adalah yang paling utama.

(instalasi jalur grounding penangkal petir dari puncak menara)



(instalasi jalur grounding penangkal petir (zoom-in))


Kemudian karena setiap "kaki" menara juga harus dihubungkan dengan sistem pentanahan situs secara keseluruhan, jadilah kami pasang juga jalur kabel tembaga yang diintegrasikan ke perimeter site di bawah tanah. Semuanya, sekali lagi, adalah demi keamanan situs.

Tentu saja lingkup pekerjaan kami termasuk instalasi mekanikal elektrikal di dalam shelter milik si operator. Sesuai gambar rencana, kami memasang lampu TL di plafon shelter, juga alat pendeteksi panas dan asap. Semua sistem alarm itu tentu saja dihubungkan ke perangkat RBS operator via semacam terminal box sehingga bila terjadi sesuatu yang memicu alarm aktif, perangkat radio akan mengirimkan sinyal ke kantor pusat pengendali operator. Ini biasanya akan menyebabkan seseorang ditelepon dan secepatnya mencek kondisi situs yang mengirimkan sinyal tersebut. Entah itu malam atau siang hari, cerah atau hujan badai. Merekalah tim pemeliharaan.



(indoor lamp, smoke detector, heat detector)



(alarm box)


Untuk mempertahankan suhu di dalam shelter agar kerja perangkat radio bisa optimal, kita tentu saja harus mengatur suhu dalam batas yang wajar dengan batas operasional. Kami memasang unit pengatur suhu udara (biasanya dua buah) dan untuk sirkulasi udara dipasang ventilasi yang biasanya tertutup bila kipas pembuangan tidak menyala.



(AC indoor unit, thermostat pada RBS, dan air inlet)


Kipas pembuangan menyala jika suhu di dalam shelter dideteksi oleh thermostat lebih tinggi dari (biasanya) 26 derajat Celcius. Dengan menyala otomatis menggunakan daya dari batere perangkat radio operator, suhu dalam ruangan tetap berada dalam kisaran suhu optimum operasional. Biasanya ini terjadi ketika listrik dari sumber daya utama -- PLN atau genset -- mati sehingga pengatur suhu tidak berfungsi. Kita semua kan tahu kalau perangkat listrik terlalu panas akan menyebabkan melelehnya bahan-bahan plastik disusul percikan bunga api dari kabel-kabel listrik yang terbuka. Percikan api menyambar bahan yang mudah terbakar menjadikan munculnya kobaran api lalu membakar dan menghanguskan segala barang.

Tentu saja tidak ada seorangpun yang mengharapkan itu akan terjadi.

Setelah pekerjaan take-over ini selesai, tibalah waktunya untuk serah terima pekerjaan diikuti dengan penagihan bayaran ke perusahaan pemilik menara!

Puasnya bila pekerjaan kita sukses.

Will There Be An "Iron Man"?


(image owned by Paramount)

Aku pernah menulis tentang betapa aku mengagumi karakter hero Marvel yang satu ini. Soalnya menurutku, superhero seperti ini masih mungkin untuk benar-benar diwujudkan -- apalagi bila dibandingkan dengan mutan yang rasanya impossible!

Lalu aku membaca artikel tulisan Prof. Kakalios, pengarang "Physics of Superheroes" (salah satu buku must read bagi fans fisika dan komik superhero Amerika), tentang bagaimana seorang Iron Man belum akan bisa diciptakan dalam beberapa tahun ini.

Artinya, seorang Iron Man belum akan ada wujudnya?

Sigh...

Eliminate All The Drama

And here We are, in this isolated universe, cling tightly to each other, afraid to let go, afraid of getting lost in this nothingness. You, Me, and The Void around us. We are nothing. But you are everything. This should be the right time for salvation: You and Me and Void, looked everywhere for the sign of the Saviour. Our search could end up in vain. Hopelessness engulfed Us because We are weak. Even together We are not strong enough. Your tears falling down Your unblemished cheek. It fell but then started to change. Into a blade... Broaden and widen still yet so thin that even the breadth of My hair is thicker than Your Blade of Tear. It slowly fell down as Your hand went up to reach It. I was very afraid. Afraid of Your fearfulness. Afraid in Your fear You will let go of My arm and hold the Blade in both of Your Arms.

Ressurecting A Smartphone

On a Thursday night, I got an unpleasant surprise. My smartphone's touchscreen damaged, I guess because I carelessly bumped it to the truck in our workshop when my men were loading reinforcement steel bars for our Jawa Tengah Area project.

One third of the screen looked like it has been smashed with something that left the liquid crystal splattered all over the screen. I got a hard time reading my contact book that night. And I curse my carelessness.

So the next day I resort to my Siemens candy bar phone that I haven't been used for almost half a year. Yes, I got another phone that I haven't use for two years now.

Anyway, I asked a colleague to try to something that could (probably) helped ressurecting my PDA from near death. Thankfully, he agreed. Here is the story in pictures:


He opened the back and plug out the battery.


Then he tried pulling out the upper back case and thus reveal the camera protector.




Then he pried open the back case entirely and now we got to see the circuit board. But now we realized that the backside case can't be released because there were two small wire attached to the speaker that were glued to the case. And the space was so tiny we got an opening only a couple of centimeter.




Since we got no pincers at hand, we had to resort to nail clippers. Surely a mind-boggling exercise that required a certain level of dexterity with hands.

After that, he tried to open the front-side case because that's where the LCD were being attached to.


Here was the front side of my smartphone with the LCS still attached to it. Next we had to pry it loose. Hmm....


Not that hard though, here is the circuit board, removed from the case and the LCD.


And here is the LCD that need to be replaced.

So we went to ITC Roxy that afternoon and went hunting for sparepart kiosks that were scattered among the 5 floor of the building. We had to bargain for the replacement for half an hour just to get Rp.50.000,00 discount.




Back to the office, we get my trashed PDA and then start working on it again -- he did the pick-up and I did the documentation.


Here was the replacement ready to be installed.


Here was half of the PDA (the backside) and both of the LCD screen.


Here was another part of the PDA (the circuit board where the LCD screen had to be attached to).


We tried to temporarily attached the LCD screen to the circuit board then inserted the battery to the terminal and then turn it on. Voila! It lighted up!

Hooray!!!


Here was the front side of the PDA with the new LCD screen were being firmly installed.


And here was the pair ready to be reinstalled again. I was impatiently waiting for the moment of revelation...


He carefully attached both parts including the wiring for the speaker. Using the same nail clipper to push it into the proper terminal.


Carefully, slowly, deliberately, reattached both parts. Then after put the screws back, inserted the battery and turn the unit on.


Hallelujah!

My smartphone live again!!!
