nasib? apa sebenarnya nasib itu?
menurut kamus besar bahasa Indonesia, nasib yang merupakan suatu kata benda berarti sesuatu yg sudah ditentukan oleh Tuhan atas diri seseorang; takdir.
Something which is has been designed by God. Itulah nasib.
Teringat film yang disutradarai Danny Boyle, di awal tahun 2009 an, yang dibintangi oleh Dev Patel, pasti semua sudah tau, film yang memenangkan 4 kategori di golden globe award. Iya, Slumdog Millionaire , menarik menurut saya tentang jalan ceritanya, yang tak dikira kira dia bisa menjawab semua pertanyaan yang diajukan di kuis itu, dan semua karena 1 hal, NASIB.
Tak ada seorang pun manusia di muka bumi ini yang tahu tentang nasib yang akan menimpa mereka, kita hanya diwajibkan percaya akan adanya takdir Tuhan.
Ga ada yang menyangka kalo saya, yang hanya seorang anak karyawan sebuah toko buku swasta di kota solo dan beribu seorang guru SMP di salah satu sekolah swasta di kota solo, akan mengakhiri level pendidikan di bidang perminyakan.
Mana tahu dulu orang tua saya kalau memang ada jurusan seperti ini, tidak ada yang tahu. orang tua saya tidak terlalu muluk muluk dalam memasang target untuk anak anak nya, mereka hanya berharap anak nya bisa menjadi salah satu contoh yang baik untuk warga di kampung nya. atau bahkan menjadi Imam masjid. Mungkin menurut mereka itu gampang, tapi itu hal tersusah buat saya untuk merealisasikannya.
back to topic, saya sendiri saja tidak pernah menyangka akan melanjutkan ke jenjang ini, sudah berulang kali saya tulis di blog saya ini, tak kesengajaan dari keinginan menjadi dokter dan akhirnya malah menyimpang 180 derajat ke teknik.
sekali lagi tidak ada yang mengetahui ilmu yang bernama nasib.
hari ini pun demikian, sudah hampir 4 tahun saya kuliah, dan masih mengambang tidak ada bayangan tentang apa yang akan terjadi kepada saya esok kedepannya.
akankah saya akan menjadi pengangguran? kerja serabutan? kerja di salah satu oil company? di salah satu services company? menjadi ranger merah? atau bahkan ranger biru? tak ada yang tau semua itu.
hanya bisa bermimpi dan mempertanyakan nasib, tapi apa hanya harus diam?
tidak, nasib akan datang kalau kita berjuang, dan mimpi terealisasi :)

God Save The Queen!!!
tau kan itu judul apa? Itu judul national Anthem nya Britania Raya.
Bayangkan, satu negara se Britania raya, mendengungkan lagu ini hanya demi memohon kepada Tuhan untuk melindungi ratu mereka. Betapa berharganya ratu mereka.
Dan hari ini, gw berharap, ada ribuan orang menyanyikan itu lagu, tapi liriknya kira2 diganti "God Save Afif", gw butuh semacam support yang agak hiperbol untuk mendongkrak semangat gw yang bentar lagi kudu nemuin dua Doktor di kampus gw buat bimbingan, yaah, finally Draft Skripsi gw kelar juga.
kalo ga percaya, nih penampakannya
Udah hampir 4 bulan gw ngerjain nih skripsi, mungkin bisa dibilang antara hidup dan mati, lebai sih, emang gw nya suka lebai hahaha..
sebenere bisa cepet sih ngelarin nih Draft, gara2 beberapa hal aja yang ngebuat gw agak ngeper juga buat ngelarin nih Draft.
1. Project.
gw kebetulan kegabung dalam Full Scale Waterflood Plan Of Development Project salah satu perusahaan Minyak di Indonesia, tugas nya ngebayangin adanya perubahan atau pun dampak adanya injeksi pendesakan Air pada salah satu lapisan di Perusahaan tersebut menggunakan simulator, cukup menguras waktu, mental, tenaga, dan perasaan. Tapi membahagiakan kantong dompet. hahahaha...
Kira2 kerjaan gw kayak gini nih kalo di kantor.
ADUUHH!! maksudnya ini nih...itu sebelah meja gw. hhahah..
Yaah, itulah simulasi reservoir, menggunakan suatu tool bernama Reservoir Simulator, kita akan dapat memprediksikan suatu performance dari reservoir Minyak bumi. Reservoir adalah suatu barang yang tak bisa dilihat dengan mata telanjang, harus dimodelkan oleh geologist menggunakan soft ware, misalnya Petrel (Schlumberger Product) yang nantinya akan di export ke Reservoir Simulation Software seperti CMG ( yang gw kerjain) atau juga bisa pakai Eclipse (Schlumberger).
Simulasi reservoir merupakan salah satu metode modern dalam menentukan cadangan dari Reservoir. itulah kira2 gambaran dari simulasi.
2. Dosbing
Dosbing atau Dosen pembimbing itu dua orang yang hebat dalam reservoir, Dr. Ir. Deddy Kristanto, M.Sc. dan Dr. Ir. Yosaphat Sumantri, MT. kalo diibaratkan di game, gw lagi kena Combo meeen. (---.---)v
Dua dosen reservoir langsung turun tangan buat nanganin orang kayak gw. Padahal kalo boleh jujur, gw idiot di Reservoir, secara basic gw itu di Drilling. tapi ga tau kesambet ape, tiba2 Kompre ambil Reservoir, dan akhire TA reservoir juga.
kenapa gw gasuka ama reservoir? udah sering gw bahas disini, gw kena jackpot 3 kali dapet C di tekres (Teknik reservoir red.) gatau kenapa, apa gw nya yg bloon, atau dosennya yang kepinteren. gw selalu aja dapet C.
Hanya karena suatu materi yang bernama MATERIAL BALANCUK!
ga tau kenapa, selalu aja, 3 kali berturut turut, tiap UTS, dengan materi sampe volumetrik, gw lancar jaya, tapi abis UTS, pas UAS, gw MATI JAYA!!
Gw jadi mikir, betapa berdosanya Schilthuis sampe sampe dia nyiptain persamaan yang namane MATERIAL BALANCUK!!
Sebenere itu gampang kok, cuma hukum kesetimbangan volume, maksudnya, antara underground withdrawal itu sama dengan pengembangan volum gas, minyak, dan semua parameter didalamnya. gampangnya, kalo minyak keproduksi, faktor yang ngebuat minyak itu bisa naik ke permukaan itu nilainya sama. Cuma kayak gitu aja kok. tapi ga tau, betapa idiotnya gw ampe kayak gitu aja ga ngerti.
hadeeeh...
Dan sekarang tanggung jawab baru pun akhirnya muncul.
Gw ga peduli mau dihabisin, dimaki ama dua dobing gw itu, yang penting gw cepet kelar dan jadi MUHAMMAD AFIF IKHSANI, ST.
GOD SAVE THE PIG! eh, GOD SAVE ME!!

CBM in Indonesia? So why we are not trying for this?
While i am doing my final year project's report, and people demands who has asked me to write down about CBM, here i would like to write about this such of subject. Coal bed methane (CBM), one of the example from unconventional hydrocarbons which is started to take a role in energy sustainability in this world.
This figures show about the production process of CBM.
In the US, coalbed methane (CBM) production currently stands at 3.5 Bcfd, about 7% of national gas production. New emerging coal basins (Uinta, Raton, Powder River) have been brought on line while mature areas (San Juan, Warrior) have maintained production.
Over 15 Tcf of CBM reserves have been booked to date, requiring more than $4 billion of capital investment ($0.30/Mcf). CBM E&P is now being conducted outside the US in China, Australia, Poland, and several other countries. As coal producing country, Indonesia CBM resource can simply be identified but quality and deliverability have not been tested. It may have considerable potential as a new gas resource.
As a new alternative energy resources a sequential challenges will require serious, well planned, long-term efforts to ensure a success of CBM development. This campaign is designed for those looking for alternative energy business opportunity in Indonesia, exploration managers and technical experts to provide an early understanding of coalbed methane geology, production technology, regulatory requirement and potential market and economics.
Why Coal bed is unique?
Coal is a gas reservoir that responses predictably to a specific set of interactive physical properties (as other gas reservoirs). Coal is a self-sourcing reservoir, thereby fulfilling the requirement of Source rock, Reservoir rock and Trap.
Coalbeds are an excellent storehouse for natural gas. They can hold two to three times as much gas as a conventional sandstones reservoir at the same depth.
Challenge is locating areas of adequate permeability (several md or more ) in otherwise tight coal seams to produce this resource.
However, in general there is agreement that the world’s supply of conventional crude oil will peak between 2020 and 2030. Most experts do not consider he contribution of unconventional oil and gas of the kind discussed in this lecture, because it seems too speculative. However, it is reasonable to state that any assumption related to decline in oil production will result in increase in oil price is necessarily not correct as oil supply from conventional sources will be replaced by oil production from unconventional resources. This obervation implies that global peak oil production will probably be not achieved probably for another 50 years.
Due to small dimensions of the micropores, a large internal surface area exists within the coal matrix. When a methane molecule comes into contact with an internal surface, two storage mechanisms are possible. The first mechanism of entrapment occurs when the gas molecule penetrates the surface and resides within the molecular lattice of the coal. This is an absorption process. the second mechanism occurs when the gas molecule adheres to the surface. This is an adsorption process. Both storage mechanisms are theorized to occur in coal.
The adsorption process can be classified by the forces which cause the gas molecule to adhere to the surface. If these forces are chemical in nature, such as strong chemical bonding, then the process is chemisorption process. If, however, the forces are physical, such as electrostaic forces or Van der Waal’s forces, the process is a physical adsorption process. The major portion of the gas stored in coal exists as a physically adsorbed, molecular monolayer.
Theoretically, the physical adsorption process is reversible. In coal, hwoever, a small degree of absorption and chemisorption occurs along with physical adsorption. Consequently, a hysteresis effect is often observed between experimentally determined adsorption and desorption isotherms.
So why CBM is Potentially Important to Indonesia?
CBM is Completely new undeveloped natural gas resources (but also untested)
Large resource potential given Indonesia’s sizeable coal base Location onshore may be more favorable for market compared with LNG of Eastern Indonesia. It is potential for advantageous “Global Warming” credits should market in tradable emission options develop
Indonesia, for this ESDM has a target to explore this mentioning area.
Formations: Eocene Tanjung
Oligo-Miocene Talang Akar
Mio-Pliocene Muara Enim
Other equivalents
Major Basins: S & C Sumatra
S Kalimantan (Barito)
E Kalimantan (Kutei, Berau, Tarakan
Plus several smaller basins.
Why we are trying to use CBM as a new alternative energy?
1. Oil & Gas Prices Trend
2. Horizontal / Radial drilling technology courses CBM exploitation cheaper and more certain
3. EOR Technology can be used to exploit CBM
(Nitrogen Injection can increase Methane recovery 50 %)
4. Processing Technology allows “Insitu Gasification”
5. Cryogenic Method (LNG) in gas transportation will solve
high cost in high compression of CBM as a consequence of Low Producing Pressure
In Indonesia itself, there are several companies which are starting to develop this kind of energy. Pertamina, Medco E&P, Vico Indonesia, Ephindo, and etc. have been starting to do this development project of CBM.
So why we are not trying this? to be develop in Indonesia :)

Kenapa harus ditulis?
Yogyakarta, 15 Juli 2011 12.35 AM.
Iseng nulis dikala kepala lagi cenat cenutnya. dan ini adalah posting ketiga ku setelah kemaren kemaren nya selalu mandeg buat nulis, berhenti di bait pertama.
hari ini mau nulis agak serius, mengenai hidup saya, ga ada lucu2an karena lagi capek dan ga mood buat ngelucu, dan bukan karena saya punya muka tampang badut.
oke, kita ngomong serius.
gajadi deh, pada ga niat buat baca kayake, ngantuk. tidur yaaa. :p
