Abstract

http://dx.doi.org/10.17014/ijog.vol3no4.20081Lithologically, the Nampurejo Pillow Lava, Kebo and Butak Formations, which are dominated by volcanic rocks, spread west - eastly, along the northern foot of the Baturagung Mountains. The Nampurejo Pillow Lava, which has an Early Oligocene age, is overlain by the Late Oligocene - Early Miocene Kebo and Butak Formations successively. The Nampurejo Pillow Lava consists of basaltic pillow-lavas showing pillow structures and they are intercalated by black sandstones. The Kebo Formation comprises alternating sandstone and pebbly sandstone with intercalations of siltstone, claystone, tuff, and shale. On the other hand, the Butak For- mation is composed of polymic breccia with intercalations of sandstone, pebbly sandstone, claystone, and siltstone/shale. The three units were deposited in a deep – shallow marine basin, which was filled by volcanic prod- ucts. Compared to the lower part of the Kebo Formation, volcanic activities during the deposition of the upper part of the Kebo Formation and the Butak Formation were more active.

Abstract

Basement rocks of eastern part of Sulawesi, from the East Arm to Southeast Arm, are composed of continental and ophiolite origins, which were collided in latest Oligocene – Middle Miocene. After collision, extention occurred in the area that formed a deepening basin in where Sulawesi Molasse was deposited. Some continental terranes distributed in the eastern Sulawesi, could be derived from northern magin of Australia, and the ophiolite was a part of the Pacific Ocean.Key words: ofiolite, continental terrane, collision and basin

Abstract

The Pendul Intrusion consists of andesite, diabas, diorite, and gabbro; that are widely distributed within the Jiwo Hills, south of Klaten, Central Jawa. K/Ar datings of 4 rock indicate that there are two magmatism episodes; Middle Eocene - Early Oligocene (39,82 - 30,04 Ma) and Middle Miocene (17,22 - 13,85 Ma). Trace element concentrations of the Pendul rocks characterize that the magma was originated from subduction environment as a result of mantle wedge melting. The rocks are characterized by low Nb relative to K and La contents. The rare earth element signatures indicate that the Pendul magmas might have come from defferent parent magmas. The Middle Eocene - Early Oligocene parent magmas posses lower rare earth element concentrations than those of the Middle Miocene ones. Keywords: Bayat, Pendul Intrusion, two magmatism episodes, stratigraphy

Abstract

The geological structures in the study area are dominated by faults. The rest directions of the faults are northeast-southwest (16 faults) and north-south (14 faults). The remainder of faults are trending in northwest-southeast (3 faults) and west-east (3 faults) directions. Generally, the northeast-southwest and north-south trending faults are dominated by sinitral faults and a few of them are reactivated as normal faults. Whereas the northwest-southeast and west-east trending faults are mainly dextral and or normal faults.Key words: fault, sinitral, normal, and lineament

Abstract

Semilir Formation crops out widely along the Southern Mountains, the southern part of Central Jawa. This formation plays an important role in both stratigraphy and magmatism of the area. The formation is conformably underlain by turbidite-dominated sediments of Kebo Butak Formation and the upper part is overlain by the volcanic breccia of Nglanggran Formation. On the basis of lithological variation, the Semilir Formation can be distinguished into four units: sandstone, lapilli tuff, pumice breccia and andesitic pumice breccia.  Calcareous clay within the sandstone unit contains nannofossils which indicate an Early Miocene age. On the other hand, fission track datings of zircon, which is contained in the pumice of the pumice breccia facies, have resulted in the ages of 17.0 + 0 Ma and 16.0 + 1.0 Ma or latest Early Miocene.The depositional environments of the formation indicate a shallowing upward sequence, and volcanism was very active during the deposition of the upper part of the formation. The pumice breccia and andesitic pumice breccia units were deposited in a relatively short time. Keywords: age, stratigraphy, lithologic unit, fission track

Abstract

the central part of the Southern Montains, which extends east-west from Parangtritis (Yogyakarta) to Baturetno Plain (Wonogiri, Central Jawa), is typically formed by clastic and carbonate sediments with volcanic rocks. Volcanic activities had been very intensive during Late Oligocene - Early Miocene. Based on their lithologies, the Southern Montains can be divided into: pra-volcanic, volcanic and postvolcanic (carbonate) periods. The rocks formed during pre-volcanic period are as the basement of the rocks which were formed during the volcanic period. Results geological mapping/study in this Southern Montains are pesented in this paper, e.g. similar formations can be divided into smaller lithologic unit, therefore the formations can be proposed into groups. Key words: Southern Montains, lithostragraphy, volcanism period, basement rocks

Abstract

Cendawan Dark Septate Endophyte (DSE) adalah sekelompok cendawan endofit yang memiliki hifa melanin gelap, membentuk koloni berwarna gelap pada media agar dan mampu mengkolonisasi akar tanaman tanpa menyebabkan gejala penyakit. Belum ada laporan yang berkaitan dengan peran cendawan DSE sebagai agens pengendali penyakit akar putih, khususnya di Indonesia. Penelitian ini bertujuan untuk mendapatkan isolat DSE dari Indonesia dengan cara menseleksi isolat cendawan DSE yang berpotensi sebagai agensia hayati penyakit akar putih pada tanaman karet. Tahapan awal dari penelitian adalah isolasi cendawan DSE dari akar dan tanah di sekitar perakaran karet, uji patogensitas, uji dual culture dan uji metabolit senyawa volatil. Dalam penelitian ini, diperoleh lima isolat cendawan DSE APDS 3.2, TBMDS 2.4b, TMDS 2.1, TMDS 3.2 dan SBTBMDS 1 yang mampu menghambat pertumbuhan Rigidoporus microporus penyebab penyakit jamur akar putih pada tanaman karet. Penelitian ini membuktikan bahwa isolat cendawan DSE bisa diisolasi dari akar tanaman karet dan berpotensi sebagai agensia hayati Rigidoporus microporus penyebab penyakit jamur akar putih pada tanaman karet. Penelitian selanjutnya akan dilakukan pengujian lapangan dan diharapkan hasil dari penelitian ini akan memberikan informasi awal tentang peran cendawan DSE pada tanaman karet dalam mengatasi cekaman biotik yang disebabkan oleh cendawan pathogen.
