Penelitian Destilator Air Laut (Tribute To Ashri Putri Rahadi)

destilator.... hmmm, untuk 3 tahun terakhir ini, ada 2 penelitian mengenai destilasi air laut di Laboratorium Energi Thermal dan Dasar Mesin, ITB:

1. Destilator yang dirancang oleh 3 bersaudara Kang Dadang (M99), Tessy Nayoan (M2000 ITENAS), dan Mba Rara (S-2 TL2001), ide yang mereka berikan adalah membuat suatu destilator beserta juga pemanas air surya, seperti yang telah aci paparkan di dalam awal blog ini, namun, bedanya adalah destilator ini terbuat dari bahan plastik fiber glass tembus pandang sebagai bahan destilator dan kaca untuk atapnya, artinya, bahan ini memiliki ketahanan yang lemah akan thermal fatigue, sehingga 3 bulan setelah percobaan, Fiber glass ini sudah tidak berbentuk baik lagi. Satu-satunya keunggulan dari Bahan plastik ini adalah seluruh permukaannya tembus pandang, sehingga dapat meneruskan radiasi lebih banyak. Di akhir percobaan, akhirnya 3 bersaudara ini mencoba untuk hanya memakai destilator. Anehnya, tanpa adanya (bantuan) pemanas surya, destilat yang dihasilkan lebih banyak.

2. Penggunaan destilator saja dalam destilasi yang menghasilkan lebih banyak inilah yang mendasari duo Rahman Nababan (M2000 ITENAS) dan Marbun (M2000 ITENAS) untuk menelusuri hasil destilasi lebih lanjut. Lain halnya dengan penelitian sebelumnya, penelitian kali ini menggunakan bahan pelat baja (dicat hitam) sebagai bahan destilator dan kaca sebagai atap. Dengan pelat baja ini, ternyata menghasilkan destilat yang lebih baik, karena mereka menambah luas permukaan dari destilatornya (CMIIW). Duo ini juga mempelajari sudut kemiringan atap dari destilator. Namun, karena memakai pelat baja, mereka mendapatkan masalah baru, yaitu karat yang terjadi pada destilator mereka, walau pun mereka melapisi dasar destilator dengan Galvanized Steel Plate (Plat Seng), namun ketika lapisan Zn habis, akhirnya bajanya juga terkorosi (Ingat kembali: Metoda Pasif pencegahan korosi, Deret Volta).

Tentu saja, dari 2 penelitian terdahulu ini, masih menimbulkan suatu tanda tanya besar, suatu motivasi untuk menghasilkan destilator yang lebih baik, yang tujuan akhirnya adalah:

Destilator yang dapat diaplikasikan penggunaannya di masyarakat

Terlepas dari ide-ide desain yang diutarakan oleh Dosen Pembimbing Achie, saya yakin, achie memiliki banyak ide lain di kepala untuk diejawantahkan. Muntahkan semua, biar lega. Karena Ide yang terbodoh pun masih berharga, dan kita tidak akan tahu kebenaran mutlak dari suatu desain, yang selalu berkembang seiring dengan berkembangnya bumi ini.

Semoga berhasil, ASHRI PUTRI RAHADI, saya mendoakanmu.

goofy driving experience

Well, it began when my friend, Aldy, got to go for industrial visit out of town, and he worried in parking his car because the car park just open from 8am - 5pm. He worried due to so many car theft these days.

So he came to me and start to ask,
"Mup, are you planning to go somewhere today around 5pm?"
"No", i said
"Well, i'm going to go to tea factory, and i'm afraid it will be until evening"
"Yes, anything i could help?"
"Hahaha... you get the point, could you take care of my car, my honda jazz, and bring it to inside the campus, because, i feel not save to park my car outside."
"Yes, i could, i ain't go anywhere around that time"

Then he gave me the key, and start to explain in brief how to operate his car, because it's automatic one, different from the usual.

He ask me one more time,
"Can you drive?"
"Rrrrr... yes, i can"
He didn't ask how good i am, so in this situation, i ain't lie to him, because i frankly can drive a car, but, it was over than 5 years ago, since then, never have driven again.

--5pm--
I grab the key, and... feel nervous, so I called kak Putra to accompany me, to relieve my nervous, stupid isn't? well, if you are in my position, you're gonna do the same.

I said,
"Could you accompany me to take my friend's car from car park"
"Hmmm... yes, but before that, let's stop to nearest shop to buy some food"
"Thanks... let's go"

We bought our food and finally arrive to the car park.
"Thanks for accompany me."
"No big deal."
"I have confess to tell."
"What's it?"
"I forgot how drive, it's been 5 years ago."

I think it's O.K to forgot, because after live in other town for studying, just once or twice driving a car, well i don't have my own car instead.
"It's O.K, just, remember your 5 years ago."
"Brilliant!"

But it's different, the car it's fully automatic, so i grab the manual from the dashboard which Aldy have told me if i have some difficulties, i can read the manual.
5 minutes passed. My friend helps me to understand it. Then,
"Well, shall we go?"
"Yes"

"Mup, Have you understand the manual?"
"Nope, I just scanning it along."
"Well OK Mup, may God bless us."

Brrrr..... brrrrr..... Oh God, if this a kind of breakdance or some car of RnB fan's, that would be cool, but this is goofy, the car start going and stopping, going and stopping again. Until at the turning to the main street, "Good God, we're going to cross the traffic jam." Luckily kak Putra is one of the most calm person which I know, then he just said, "Relax Mup, just wait and see." Even though I've said "Yes" but my body tell different than my mouth, sweat's everywhere, and my heart beats as if some dance music, "thud...thud...thud..."

Finally, a kind person gave his way to me to cross the street. And then, with another bumpy jumpy driving skill, I cross the street. kak Putra just smiled with it.

5 minutes on street calmed my heartbeat down, shut the sweat of my body off. kak Putra opened, "Mupi, you lied, this is your FIRST driving experience, right?" trembling, I said, "Rrrr... yes it is, kak." Suddenly he bursting out, "HAHAHAHA.... you should see your own face then, it's terribly funny. Your round face is red like and an apple, and you sweat much as if you have athletic competition." I just raised my eyebrows, "Come on kak, it's okay for beginner I guess." He replied, "If you're beginner, then you have to BEGIN to learn driving first." Yeah, he's right, what i was doing was terribly goofy.

Finally, we come to our destination, and park the car. Go out and then, lock it with full breath I said, "We're lucky."

a new moment to see
