Dear Indonesia,

Please, jangan jadikan Indonesia sebagai Racist and Bigotry seperti isu yang sedang berkembang di Amerika .....
I always see their news, and it was really fucked up
Ketika polisi-polisi mereka membantai "African-American"
When the majority of Trump Supporters told immigrant to leave their own country 
Ketika Muslim-American dicerca habis-habisan karena mereka dianggap Terrorist karena ulah beberapa orang yang bahkan tidak mencerminkan Islam sama sekali - Thanks to Ignorant people, though
Ketika Muslim-American tidak lagi punya suara karena mereka berada pada posisi Minority

Ini bukanlah Indonesia yang aku tahu
Indonesia -yang katanya- punya 700 lebih etnis, 1000 dialek, dan ke-Bhineka-Tunggal-Ika-an
Ini bukanlah Indonesia yang aku tahu
Indonesia, yang kemerdekaannya, merupakan perjuangan seluruh manusianya pada jaman itu, tanpa memandang "Aku dari agama mana atau etnis apa"
Indonesia, yang dulunya, hanya punya satu tujuan, yaitu Merdeka

Indonesia, kau lebih baik dari ini!
Please Stop! Tolong hentikan!
Hentikan kata-kata "Mayoritas" ataupun "Minoritas" mu itu
Aku tidak mau memiliki sifat para "Pembully"
Please Stop! Tolong hentikan! 
Aku tidak mau, Indonesia yang menganggap Agama selain Islam sebagai minoritas yang harus menghormati orang yang merasa mayoritas ini
Kalau begini, apa bedanya kita dengan orang-orang Barat disana?

Dear Indonesia,
Ayolah, jangan mau dipecah-belah lagi
Ayolah kita satukan visi-misi, bukan lagi karena satu Etnis ataupun satu Agama, tapi satu Indonesia
Ayo Indonesia, Bangun!
You're better than this!




PS. It's not poetry, It's just my personal thought about How fucked-up our Indonesia is, and What kind of Indonesia I want. Indonesia Darurat Toleransi!

Kado Terindah Natal untuk Kevin

21:39 rafi 1 Comments

Halo guys ! Tulisan ini gue dedikasikan untuk Kevin, sebagai salah satu sahabat Gue. Hehehe

"KEV, INI MASIH DIAGNOSIS, TUNGGU PROSEDUR SELANJUTNYA!" Begitu ucapku.

Akupun mencoba mencari tahu hasil diagnosis tersebut (begitu pula kevin). Lagi-lagi, hasil di google malah memperparah semangat kevin saat itu. Lagi-lagi, tak henti-hentinya kami menyemangati Kevin!

"Tenang kev, ini belum final, kita ikuti prosedurnya. Kalau kata teman gue yang dokter, yang penting penyakitnya dulu ketahuan. Biar tahu pengobatan yang benernya seperti apa. Serius ! Semangat kevinnnn!" 

Sampelah disaat kevin dirujuk di RS persahabatan, dan akhirnya diminta untuk tes TTNA. Lagi-lagi, harus cek darah bla-bla yang sempat bikin kevin down. 

"Sejujurnya gue udah lelah nih gaes"

Yasss, semangat terus bertubi-tubi datang (dan ga mau berhenti). Percakapan pun terus-menerus gue lakukan. Gue kontak si Kevin setiap hari walaupun hanya sekedar nanyain kabar. Huhuhuhu. "Semangat" adalah satu kata sederhana, tapi luar biasa powerful menurut gue. It really is effective, though!

Hasil TTNA keluar ! Tidak ditemukan sel ganas, pungkasnya. "Puji Tuhan! Ya Allah Alhamdulillah", gue bilang ke kevin. Tapi, karena belum ketahuan penyakitnya apa, kevin pun dirujuk untuk Bronkoskopi. It looks painful, though. Tapi lagi-lagi, kevin harus dijaga semangatnya, karena ga baik kalo dari diri doinya aja udah ga semangat dan stress banyak pikiran. Saran temen gue yang dokter sih,

Berdasarkan bronkoskopi, tidak ditemukan sel ganas, tapi ...... kata dokternya udah Stadium 4 ...... Kevin literally menghilang selama 3 hari ...... Balik-balik muncul, bilang kalo dia sempat stress bla-bla-bla ........ yang gue lakuin, lagi-lagi menyemangati. Dan karena dulunya nyokap gue kena kanker, gue sarani kevin pergi ke Penang, Malaysia. Tapi dibatalin karena kata dokter rujukan Kevin (yang sudah sangat handal serta senior), bilang percuma kalo penyakitnya belum diketahui. Usut punya usut, Kevin dirujuk untuk ngelakuin VATS Biopsi, yang ternyata luar biasa mahal (Rp59.000.000), thanks to BPJS, once again, semua ditanggung :"

Voila, tepat hari ini, satu hari sebelum Natal, Kevin sempat ngabari kita kalau hasilnya Negatif untuk Tumor dan Kanker. Fix ini seperti dugaan dokter seniornya, yang ngomong bisa jadi ini TB (dan beneran). Yeeeee! Gue senang-se-senang-senangnya, sempet mau nangis juga terharu, akhirnya doa kita bersama-sama terkabul :" Bagi gue sebagai sahabatnya, it's so BIG! Dan gue yakin, bagi Kevin ini adalah Kado Terindah Natal untuknya.








PS. I don't need your opinion about "Why you said Merry Christmas to Kevin? Why these ..... why those ....." I don't really care, though. Because, I knew, lots of my best are non-Muslim, and I am glad to know them, though. And, I think it's ok to say it for them as long as I keep my Aqidah by myself. Thanks 

What Makes Bandung so Windy?

21:48 rafi 3 Comments

Hello !

Currently, I was wondering why Bandung is so windy, literally. Both in Daylight or Night. It seems like, the winds were quite intense as well.

First of all, I am not talking about "Wind" that was happening when storm came. Because Storm used to followed by strong wind both vertically (to enhance the storm development) or horizontally caused by Wind Burst (in the surface though).

Based on the definition of Windy /ˈwindē/

"marked by strong wind or by more wind than usual <a windyday> b : violent, stormy." (merriam-webster.com)

So, yeah, I am talking about "more wind" though. Even though it's so windy, there's not much rain happening though. Probably, all of the clouds was moved on the other side of Bandung. Anyway, back to the first question, what makes Bandung so windy?

Well, to answer this question, I need to explain about "Wind Mechanism"

Please keep in mind, that wind blows because there's a difference between pressure from one location to another. Wind blows from High to Low pressure area, never the other way round. In local scale, we used to know about "Seabreeze and Landbreeze". It's caused by the pressure difference of land and sea. Why? Let us say, Land has lower heat capacity than sea. It means, land is easier to get hot rather than sea. In atmosphere (which is not ideal gas), the more heat, the less pressure in it. Because atmosphere is not "closed system", when you heat it, it's gonna expand and make the atmosphere Less dense.

Which means, every day, whenever there's "Sun light" that's gonna warm the surface up. There would be pressure difference between Land and Sea. In daylight, it will cause "Seabreeze", where winds blow from sea to land. Vice versa in the night, we will have "Landbreeze", where winds blow from land to sea.



Alleged Mechanism Why Bandung is so Windy

Ah, that's the first thing !
Next, I am guessing, the answer for our question would be, there's Strong Seabreeze that's happening, right now ! 

First of all, let's see the position of Sun, right now.

You're right, It's summer in South Hemisphere !

Java Island is located in Southern Indonesia, right?

1) This condition would create condition, where Java's land would be so hot, but the sea won't be (Because the capacity of heat that I was explained in the first place). The difference would be huge, and would create strong Seabreeze.


If we saw carefully, meridionally (based on its latitude), Bandung is located in the middle of West Java, right? And we know, there would be Seabreeze both from North and South of it. Does it mean, the winds would met in Bandung? No! First, because there's coriolis effect. Second, the sea breeze from South would be stronger than from the North.




What makes it stronger? Because, the Indian Ocean is deeper than Java sea. It means, Indian ocean has more heat capacity than Java island, which makes it harder to warm it. This will drive the Pressure difference more, and will make Seabreeze stronger. Even, one of my lecture said that Seabreeze from south Indian Ocean in Java Island, can across the Java island itself.

Last but not least, if you're watching "BBC: Earth Extraordinary Journey" (I literally recommend you to watch it). You may get the information, that Southern Hemisphere ocean is cooler than the Northern Hemisphere ocean in Summer! It's all because, there are more Land in northern rather than in southern.

This leads us, having more Stronger Sea Breeze because the local mechanism, right?


Conclusion

Our seabreeze probably ended up in Purwakarta or somewhere else (Idk), or even went to the Java sea as well. So does in the Night, when south Indian ocean would be warmer than Java Sea and Java island itself. Which makes stronger Landbreeze to Indian Ocean. Thanks to Summer (in Southern Hemisphere) and the mechanism of Heat Capacity, though :)

Ah, that's all about today ! Hope the hype stayed and the questions be answered yah guyzzz !

Anyway, If you have something to discuss, you can go to the comment section below! And just let me know, yah!

Yes, yes, I know, Bandung is so Cold !

El-Nino and Its Effects to Indonesia

14:21 rafi 0 Comments

El-Nino Meaning and Definition

Based on Wikipedia,

"El Niño is the warm phase of the El Niño Southern Oscillation (commonly called ENSO) and is associated with a band of warm ocean water that develops in the central and east-central equatorial Pacific (between approximately the International Date Line and 120°W), including off the Pacific coast of South America."

El-Nino is an anomaly that happens on Walker Circulation (One of global circulation that has role on Weather pattern on Earth).

So, It's easy to understand what driven this phenomenon. First, you can Imagine there are a "warm pool" across pacific, that could be shifted to eastern or western area. Because it's kind of a cycle, we can't say "Who's first ?" (kind of "Who's first? Egg or Chicken?"). But, you can say that Indonesia is the main Actor here.

El-Nino happens when the "warm pool" shifts eastward along the equator, toward pacific ocean. Normally, this "warm pool" near Indonesia and the Philippines. But during an El Niño, the Pacific's warmest surface waters sit offshore of northwestern South America. When this warm pool shifts to Nino 3,4, or 3.4 (it's kind of coordinates across pacific ocean), this is gonna affect the pressure on the areas. We know that this "warm pool" gonna make an Low-Pressure Areas, and will create its own circulation ! (Wind blows from High to Low Pressure, right?)

You can see this Picture to compare it yourself

Normal Condition vs El-Nino illustration

See? There are shifting on Convective Areas. And one of greatest effect for "Indonesia", is Indonesia could be Draught and Fire-forest could happen because of it.

Why did I use quotation mark on Indonesia?
So guys, you should understand that Indonesia is a Big Word.

Generally, you may say that "Indonesia" may be affected by El-Nino. But .... not really.
Indonesia, have 3 kind of climate-pattern based on Rainfall peaks.

1. Monsoon Pattern
The Areas with this pattern, usually have a great different between Wet and Dry season. It's clearly driven by Monsoon phenomenon, that happens because of ocean-continent temperature distribution. Eastern Monsoon would bring a lot of water from the Indian-ocean and pacific ocean, different with western Monsoon that's not really carrying moist water across Australian continent and indian-ocean.

2. Equatorial Pattern
The areas within this pattern, usually have 2 rainfall peaks because of the Sun position. We know that, Equator areas would be have 2 Equinox a year, that makes evaporation through Equatior should be maximized and for several areas, it affects them a lot.

3. Local Pattern
Basically, local pattern seems like Monsoon pattern but vice versa. It happens because the local geographic condition (usually happens on the areas near Mountain) because Orography effect.

Indonesia Rainfall Pattern according to BMKG

Generally, we can see Indonesia's pattern here. But, even if we Zoom into Bandung, West Java, we could see this pattern !

Bandung Rainfall mapping according to UNPAD

Believe it or not, the center one has Monsoon Pattern, where the yellow one has Equatorial Pattern, and the orange one has the local pattern because its mountain area. We still need a lot of Research to create climate Map on many Indonesia Areas. Because Indonesia, is really complicated one, and this makes us, Meteorologist, hard to predict the accurate Weather because the Scheme that's not really fit with Indonesia Geographic position.

Back to the Topic, El-Nino does affect "Indonesia", but you must Specify where the Area is, because not all of Indonesia areas be affected with it. Even if El-Nino happened, Bogor might still have some extreme storm though.

I think that's all guys. Hope this could give you a lot of information about El-Nino and La-Nina that's happening lately :)

Cara Menanam Hidroponik

Halo semua ! So, hari ini, saya akan berbagi tentang apa yang saya dapat saat mengadakan Untukmu Cisitu II pada tanggal 04 Desember 2016, kemarin. Percayalah, selain mendapat pengalaman dari pengonsepan, perencenaan, serta pengembangan project penghijauan ini. Ada beberapa hal yang mungkin perlu saya bagi buat teman-teman yang mungkin berhalangan hadir pada waktu tersebut.

Yups, yang pertama adalah terkait materi pelatihan di hari tersebut. Diawali dengan pembukaan dan kata sambutan dari Presiden KAM Bumi Ganesha ITB, serta Ketua Panitia Cisitu Menghijau II, materi pun langsung diberikan oleh Ibu Chie Chie dan Pak Boy Hidayat dari Green Education Bandung. Setelah melakukan perkenalan singkat serta alasan mengapa penting melakukan penghijauan di wilayah sekitar, kami pun langsung diperkenalkan dengan beberapa sistem tanam Hidroponik, salah satunya adalah Hidroponik wick sederhana. Bahan yang digunakan hanyalah Botol Air mineral 1.5 Liter + Sumbu + Spons

1. Diawali dengan membagi botol air mineral 1.5 L menjadi 2 (dimana bagian atas lebih lebar dibandingkan bagian bawah)
2. Kemudian pada bagian atas botol, diberikan beberapa lubang yang berguna untuk sirkulasi oksigen (aerasi)
3. Adapun bagian tutup botol dilubangi sedikit dan dimasukkan kain flanel / sumbu sebagai medium tanaman untuk mengambil air.
4. Setelahnya, ambil bibit/benih tanaman (tidak perlu menggunakan tanah)
5. Bibit yang telah dibersihkan tanahnya tersebut, kemudian dibungkus dengan media (bisa dalam bentuk spons)
6. Kemudian letakkan bibit yang telah diberi media ke bagian tutup botol tadi.
7. Isi bagian bawah botol dengan air nutrisi yang berisi nutrisi Makro (Nitrogen, fosfor, dan Kalium) dan Mikro (Boron, tembaga, besi, dll)

About Me

13:39 rafi 0 Comments

Hello, my name is Muhammad Rafi Al-Hariri Nasution, I am currently studying in Meteorology Department, Bandung Institute of Technology :) You can call me Rafi, Tanjong, or Ari. I am taking minor in Atmospheric Science and Environmental Meteorology. Atmospheric science was studying about Weather and Climate prediction, but it's much deeper. We were focused on Mesoscale prediction, which is really important for short and long term decision making. Not only mesoscale prediction, we used to learn about Atmospheric teledetection (observation using radar) and ocean and atmosphere interaction. Environmental Meteorology was studying the impact of physical meteorology for the environment. Climate Change, Climate Policy, Agrometeorology, and air pollution modelling is the main subject of Environmental Meteorology.

Big data analysis (3-D, 4-D, and even 5-D of data) has been our main concern. Because in Meteorology, we tend to analyzing data temporally (T), spatially (X and Y), and even vertically (Z). Tools like matlab, excel, fortran, phyton, and R has been our daily tools to analyze this kind of data. So basically, programming, mathematics, physics, interpretation, and even data presentation is a must skills. Because, our societies, government, or client didn't really care about the process but result, and it must be as simple as possible :) So yeah, here I am, studying in one of the most complex fluids on earth (which is so random and having high uncertainty).

My Final Assignment / Thesis is "Prediction of Australian Summer Monsoon (AUSM) and The Beginning of Rainfall Season (BRS) in Java Island by Using Climate Forecast System (CFS) Version 2 Output". Kind of interpreting the output of CFS that's predicting the rain rate, and doing the downscaling data from 1 degree to be 0.25 degree, and evaluating the CFS to predict the AuSM onset and the BRS. Soon, would be registered to International conference or scopus :)
