Re: [iagi-net-l] Fwd: Sekneg juga butuh 2 orang geologi
kok tanpa pengalaman? apa nanti terus ada comprehensive training? terus bidang geologinya apa...tambang, tata lingkungan, migas atau apa...? karena tiap bidang butuh expertise yang berbeda... Atau geologist sekneg itu nanti cuma akan menjadi pintu komunikasi buat organisasi profesional dalam memberikan inputnya seperti IAGI, Perhapi dsb? Kok kalau saya mending Sekneg mengangkat orang seperti Mas Andang dan orang lain yang ahli di bidangnya (mis dari Perhapi dsb...) menjadi staf ahli bisa official atau konsultan saja .. dan sambil pelan - pelan mempersiapkan orang buat lingkungan struktural nantinya dengan di bawah bimbingan staf ahli tadi jadi si geologist sekneg nanti bisa belajar banyak sebelum benar - benar siap dilepas. jangan sampai cuma jadi basa basi bahwa sekneg udah ada geologist tapi enggak bisa memberikan masukan yang bener Regards Ferdinandus Kartiko Samodro TOTAL EP Indonesie Balikpapan DKS/TUN/GG 0542- 533852 Rovicky Dwi Putrohari [EMAIL PROTECTED] 27/10/2004 05:31 PM Please respond to iagi-net To: [EMAIL PROTECTED] cc: Subject:[iagi-net-l] Fwd: Sekneg juga butuh 2 orang geologi Dibawah sana itu info lowongan dr Pak Mail, Yg cukup menarik adalah sepertinya sudah muncul 'kesadaran' akan kebutuhan geologist di Setneg.

[iagi-net-l] Manusia Hobbit Homo floresiensis
(Koq nggak kedengaran ada ilmuwan Indonesia yang ikut di tim ini ya...?) Menarik, disini disebutkan bahwa salah satu survival strategy untuk mengatasi kondisi yang minim resources adalah dengan mengecilkan diri. Oki - - - - - - - - - Found - the newest members of the human family By Deborah Smith October 29, 2004 A previously unknown species of miniature human barely a metre tall, who hunted pygmy elephants and giant rats, lived on Australia's doorstep until at least 13,000 years ago. Australian and Indonesian scientists have unearthed a near-complete skeleton of a female member of the species, nicknamed Hobbit, in a cave on the remote Indonesian island of Flores, 600 kilometres east of Bali. The archaic humans co-existed for tens of thousands of years with our own species and might have died out only 500 years ago. Archaeologist and team member Mike Morwood, from the University of New England, said they were about the size of a modern three-year-old. They weighed around 25 kilograms and had a brain smaller than most chimpanzees, Professor Morwood said. Even so, they used fire and made sophisticated stone tools. Despite tiny brains, these little humans almost certainly had language. The discovery of the species, published today in the journal Nature, is being hailed as one of the most important in a century in the study of human origins. Until now, it had been thought our only recent cousins were the Neanderthals in Europe, who died out about 30,000 years ago. Advertisement Advertisement The find is startling, said another team member, Dr Robert Foley, of the University of Cambridge. It is breathtaking to think that such a different species of hominin existed so recently. Named Homo floresiensis, it is the smallest species of human ever found. It is the first that overlapped recently with our species to have been discovered since Neanderthal remains were found in the 1800s. The island the small humans lived on, Flores, was a lost world inhabited by creatures as strange as they were - giant rats and giant lizards, komodo dragons, and primitive dwarf elephants that were extinct elsewhere. Bones including the skull, jaw, pelvis and leg of a 30-year-old woman were uncovered last year in Liang Bua cave on Flores and dated to about 18,000 years old. More recently, the team has uncovered her arm bones as well remains from six other little people, who lived in the cave from about 95,000 years ago to 13,000 years ago. The existence of the species will prompt a major rethink of how humans evolved, according to another on the team, Peter Brown, of the University of New England. The most remarkable thing is that someone with that sort of small brain size was behaving in many ways like a modern human in terms of hunting and the stone tools they used, he said. Professor Morwood said the little people were thought to have evolved from larger archaic humans, Homo erectus, who managed to sail across to Flores from Java about 800,000 years ago. They evolved into dwarfs, like the elephants on the island, because small creatures had a better chance of survival on a remote island where there was little food and no major predators. Homo erectus spread from Africa to Asia more than a million years ago, but were eventually replaced by our species, Homo sapiens, who left Africa about 120,000 years ago, according to the leading theory of human movement. The little Homo floresiensis species survived on Flores long after Homo sapiens had moved into the region and begun to colonise Australia and New Guinea 50,000 years ago. Bert Roberts, of the University of Wollongong, whose team carried out the dating, said there were a lot of detailed folk tales on Flores about little people. These stories suggest there may be more than a grain of truth to the idea that they were still living on Flores up until the Dutch arrived in the 1500s, Professor Roberts said. The stories suggest they lived in caves. The villagers would leave gourds with food out for them to eat, but legend has it these were the guests from hell. They'd eat everything, including the gourds. It is 110 years since the last human species was discovered in South-East Asia - the 700,000-year-old Homo erectus Java man specimen.

Re: [iagi-net-l] Manusia Hobbit Homo floresiensis
Oki, menarik posting-nya, saya yakin ini akan memerlukan konfirmasi penelitian lanjutan. Masa ilmuwan Indonesia tidak ada yang ikut, kok di artikelnya disebut ada ilmuwan Indonesia dan Australia, hanya tak disebutkan namanya yang Indonesia. Kenapa memerlukan konfirmasi penelitian lanjutan ? Sebab ada beberapa hal dari teori yang dikemukakan atas penemuan ini yang rasanya akan bertentangan dengan pengetahuan paleo-antropologi maupun paleo-vertebrata saat ini. Hobbit mengingatkan saya ke cerita2 Harry Potter, memang manusia kerdil. Dalam ekologi ada teori yang disebut biogeografi pulau yang intinya menyebut bahwa ukuran dan jumlah spesies hewan akan mengecil/membesar mengikuti kecil/besarnya pulau (jadi berbanding lurus). Hobbit akan cocok dengan ini, walaupun adanya komodo dan tikus besar terasa bertentangan (kecuali kalau komodo dan tikus besar memang hewan primitif yang endemik - berarti mereka kelak akan mengecil ukurannya kalau menerapkan teori evolusi / spesiasi karena kendala ekologi). Yang agak berat adalah teori bahwa Hobbit ini peralihan dari Homo erectus Jawa yang mengerdil karena ukuran pulau. Belum ada cerita bahwa Homo erectus bermigrasi ke Nusa Tenggara, yang ada adalah Homo wadjakensis yang umurnya lebih muda dari Homo erectus, sebab leluhur orang2 Aborigin di Australia adalah Homo wadjakensis yang ukurannya besar, yang bermigrasi ke Australia melalui land bridges sepanjang Nusa Tenggara termasuk Flores dan paparan Sahul yang saat itu kering di zaman es, apakah mereka di tengah jalan berubah jadi Hobbit di Flores, kenapa dong mereka membesar lagi di Aborigin Australia, lucu kan ? Pygmy stegodon, tak hanya ditemukan di Flores, Sartono (1969) pernah menyebutkan stegodon kerdil di Timor, dan Sartono (1979) pernah menyebutkan stegodon kerdil di Sumba. Artinya, stegodon pun bisa bermigrasi, masa Hobbit tak bisa, atau belum ditemukan saja fosil2nya di pulau2 Nusa Tenggara lain. Bahkan Pak Zaim pernah menyebut stegodon kerdil di Sumedang (entah saat itu Sumedang merupakan pulau atau daratan besar harus dilihat lagi), di endapan2 Kaliwangu di Jawa Tengah Utara pun ditemukan fosil2 stegodon kecil ini. Artinya migrasi vertebrata adalah masalah biasa, terlepas dari apakah mereka kena spesiasi biogeografi pulau atau tidak. Kemudian, ukuran otak yang lebih kecil dari simpanse tetapi kemampuannya sebanding dengan katakanlah manusia purba menarik sekali untuk dikaji sebab ini menyalahi hukum linier dalam paleoantropologi bahwa semakin besar volume otak semakin cerdas, artinya kalau Hobbit ukuran otaknya tak lebih besar dari otak simpanse maka kemampuannya tak akan lebih besar dari simpanse, tetapi kenyataannya kan lain bukan ? Makanya menarik untuk dikaji lebih jauh. Kalau kemampuan sudah ada, lalu tiba2 otaknya mengecil karena biogeografi pulau, tetapi kemampuannya tak ikut berkurang, nah ini juga menarik secara fisiologi. Kelihatannya, akan lebih cocok (dengan pengetahuan paleo-antropologi dan vertebrata sekarang), kalau berteori bahwa Hobbit bukan evolusi dari Homo erectus maupun Homo wadjakensis, memang ia hominid endemik yang sudah lama tinggal di situ. Bukankah di wilayah Wallacea ini banyak fauna-flora yang endemik ? Sekedar pendapat...Anyway, ini menarik, hanya jelas butuh elaborasi.

Re: [iagi-net-l] Melihat Kembali Tektono-Volkanik Banten Block
Menarik Pak Awang... Dari sisi batuan volkanik (igneous)-nya, Honje Complex terdiri dari 3 kelompok, secara urutan umur adalah (1) Honje volcanics, andesitic-basaltic yang berumur 10 - 11Ma (bertepatan dengan mulai membengkoknya pelurusan Sumatra - Jawa di Selat Sunda), (2) dacitic tuff dan associated rhyolite complex, yang dalam paper saya (dkk) kita sebut sebagai Cibaliung Tuff, berumur 4.95Ma (Jawa dan Sumatra sudah memisah), serta (3) basalt flows yang menorobos zona-zona struktur sebagai back arc rift basalt (?), yang ini belum ada dating-nya tapi lebih muda dari Cibaliung Tuff. Yang menarik adalah adanya time gap sekitar 5 juta tahun antara Honje volcanic dan Cibaliung Tuff dimana tidak ada aktifitas vulkanism. Apakah ini ada kaitannya dengan meredanya tectonic event pada kurun waktu tsb, sehingga volcanism juga mereda? Saya belum tahu. Untuk konsep high and low di seputaran Ujung Kulon - Honje - West Malingping, apakah Pak Awang punya paper detil ttg ini?

Dan di geologi, wilayah ini pun biasa disebut Banten Block. van Bemmelen sejak tahun 1949 telah menyebut wilayah ini sebagai Banten Block dan membuat batasnya berupa garis hampir selatan-utara dari Teluk Pelabuhan Ratu sampai Teluk Jakarta. Bukan sekedar garis batas wilayah, ternyata adalah juga garis batas geologi. Kata van Bemmelen, terdapat perbedaan arah struktur yang menyolok antara struktur2 di Banten Block yang didominasi arah Utara-Selatan dengan struktur2 Jawa yang didominasi Barat-Timur. Publikasi2 selanjutnya memang menunjukkan hal itu. Publikasi2 tektonik terbaru menunjukkan bahwa Pulau Jawa pernah menyatu dengan Sumatra, sehingga orientasi Pulau Jawa pun hampir seperti Sumatra. Lalu sejak sekitar Mio-Pliosen kedua pulau saling berpisah, Pulau Jawa terputar anti-clockwisely sedangkan Sumatra terputar clockwisely, membuka Selat Sunda semakin melebar ke arah selatan mirip2 triangle zone. Penelitian terbaru paleomagnetik Jawa menunjukkan bahwa bagian timur Pulau Jawa (datanya belum lengkap, jadi baru diketahui bagian timurnya saja) pernah menduduki paleo-latitude lebih ke selatan di banding sekarang - jadi membenarkan bahwa Pulau Jawa pernah terotasi anti-clockwisely. Kelihatannya, pemisahan Sumatra dan Jawa ini meninggalkan banyak luka geologi baik di Banten maupun di Lampung, berupa segmented basements di kedua wilayah tersebut yang berarah utara-selatan, sehingga di Banten misalnya ditemukan sistem horst dan graben seperti Ujung Kulon High - Ujung Kulon Low - Honje High - West Malingping Low. Di Selat Sunda, di pusat pemisahan ini, lebih parah lagi segmentasi-nya. Dan kondisi ini diperparah dengan aktifnya Sesar Mendatar Sumatra yang dextral dan Sesar Mendatar Ujung Kulon (di offshore baratdaya Pelabuhan Ratu). Kedua sesar mendatar ini saling berposisi step-over, seperti ber-estafet dari Sesar Sumatra ke Sesar Ujung Kulon. Daerah estafet adalah Selat Sunda, akibatnya akan tebentuk extensional stress pada kedua sesar dextral tersebut di wilayah Selat Sunda, dan terbukalah Selat Sunda melalui mekanisme pull-apart basin, sebagai konsekuensi dua sesar mendatar yang membentuk releasing stepover. Segmentasi kerak di wilayah Lampung, Selat S unda, dan Banten jelas akan terpengaruh ini, juga pemisahan Sumatra-Jawa. Konsekuensi lain, adalah banyak sintetic faults yang besar-besar yang juga punya sifat releasing, baik di Lampung dan di Banten. Nah, ini lalu berimplikasi ke banjir lava basal di Lampung dan Banten karena sesar2 sintetik ini menjadi konduit untuk lepasnya magma naik ke permukaan. Di Lampung ada Rajabasa dan Sukadana complex, di Banten ada Danau Complex dengan Gunung Karang dan Pulasari puncak2nya. Ini adalah kompleks gunungapi berupa backarc volcanism yang dikontrol sistem sesar yang rifting. Di Selat Sunda sendiri, dua arah sesar utara-selatan dan sesar arah Sumatra berpotongan, dan di salah satu perpotongannya, muncul Gn. Krakatau yang paroxysmal letusannya pada 1883, pantas saja, dikontrol dua sesar. Lalu karena ada proses penenggelaman di Selat Sunda itu, tertariklah garis palung di depannya lebih ke arah utara, membuat pola konkaf pada palung, suatu hal yang tidak lazim sebab palung secara umum adalah konvex ke arah samudera. Di luar itu, di Banten Block juga ada Bayah Dome yang terkenal itu, yang batuan tertuanya (volkanik) katanya seumur dengan Jatibarang Fm. di Cirebon. Maka di banyak publikasi ditariklah garis volcanic arc Eosen dari Bayah ke Cirebon. Benarkah semudah itu menghubungkannya ? Mestinya tidak sesederhana itu, maka perlu melihat kembali sejarah keseluruhan Banten Block. Masih banyak yang mesti dikerjakan dari wilayah ini. Sayang, terlalu sedikit

They evolved into dwarfs, like the elephants on the island, because small creatures had a better chance of survival on a remote island where there was little food and no major predators. Homo erectus spread from Africa to Asia more than a million years ago, but were eventually replaced by our species, Homo sapiens, who left Africa about 120,000 years ago, according to the leading theory of human movement. The little Homo floresiensis species survived on Flores long after Homo sapiens had moved into the region and begun to colonise Australia and New Guinea 50,000 years ago. Bert Roberts, of the University of Wollongong, whose team carried out the dating, said there were a lot of detailed folk tales on Flores about little people. "These stories suggest there may be more than a grain of truth to the idea that they were still living on Flores up until the Dutch arrived in the 1500s," Professor Roberts said. "The stories suggest they lived in caves. The villagers would leave gourds with food out for them to eat, but legend has it these were the guests from hell. They'd eat everything, including the gourds." It is 110 years since the last human species was discovered in South-East Asia - the 700,000-year-old Homo erectus Java man specimen.
