“…Hal tersebut dikarenakan oleh adanya dinamika dari aktivitas vulkanik /hidrotermal. Kawah Sikidang tercatat beberapa kali mengalami peningkatan aktivitas yaitu pada Desember 1883, tahun 1934, bulan Juli 1981 dan pernah mengalami erupsi pada bulan Maret 1884 dan pada pertengahan Juni 2003(van Bemmelen, 1949aReksowirogo, 1979;Report on Dieng Volcanic Complex, 1981). Pada 15 Januari 2009 terjadi letusan di sisi barat Kawah Sikidang, lubang letusan baru tersebut dinamai Kawah Sibanteng (KOMPAS.com, 2009;Siebert et al, 2010).…”

Sikidang crater geothermal manifestation area is located in Dieng geothermal field, Banjarnegara, Central Java Province, Indonesia. In 2019 more than 400,000 people visited Sikidang Crater tourism area. Some of the surface manifestation in this area include fumaroles, mud pools, steaming grounds, and altered ground. This research aim is to identify hydrothermal fluid below the surface and estimate the area of conductive zone using resistivity model from geoelectric data (dipole-dipole and Schlumberger configuration), surface temperature measurements, dan geological observation.Based on the results of 1D and 2D resistivity model, the low resistivity anomaly is thought to be a hydrothermal fluid that associated with surface geothermal manifestations appearence. The low resistivity anomaly also assumed to be associated with altered rocks in the study area, while the high resistivity anomaly is thought to be Pangonan andesitic lava with resistivity value above 1500 Ω.m. Several conductive zone dominantly identified in the Kawah Sikidang tourism area, however conductive zone also identified outside the tourism area.

“…Significant fossils and palaeosols sequence amassed in the dome of Solo Basin were studied pertinent to the evolution of history and dispersals during the Early and Middle Pleistocene. The dome also uncovers the movement of early hominins as early as 1.8 Ma, including the first islanders, Homo erectus, about the lowering of the sea level during the Pleistocene period, which produced many land bridges and sea barriers in Sundaland (von Koenigswald, 1940;van Bemmelen, 1949;Zaim et al, 2011).…”

“…Sangiran of the Solo Basin has a sequence of layers that are complete and continuous from the Upper Late Pliocene up to the Pleistocene. The dome was created more than two million years ago due to volcanic and tectonic activities, and numerous climatic cycles in the Solo basin (von Koenigswald, 1940;van Bemmelen, 1949;Sémah, 1986). Afterward, the dome was truncated by erosion, exposing a concentric pattern of strata, with older strata surrounded by younger (Hyodo, 2011), filling the basin with sediment deposits from volcanism, tectonic movement, and climatic cycle runoffs.…”

Abstrak. Katalog Himpunan Fosil Kerang Sangiran. Makalah ini merupakan pemutakhiran himpunan fosil cangkang Sangiran di Jawa Tengah. Tujuannya untuk mendokumentasikan dan menyajikan gastropoda dan kerang dari seri Kalibeng atas dan Pucangan Bawah Kubah Sangiran dari periode Plio-Pleistosen. Tercatat 61 taksa moluska hingga tingkat genus. Informasi yang dikumpulkan dari kumpulan moluska ditentukan oleh sejarah geologi dan lingkungan Sangiran. Mereka diasosiasikan dengan fasies yang berbeda: a) napal masif dan lempung biru, b) lapisan batugamping lempung, c) lempung kelabu berlumpur, d) breksi vulkanik dan lahar dan e) lempung hitam, dan terdiri dari sedimen yang merepresentasikan lingkungan laut hingga rawa yang mengarah ke perkembangan kontinental. Pola kuantitatif yang dicatat dalam kumpulan moluska menjelaskan palaeo-lingkungan dan hubungan antara kumpulan palaeodataset yang mapan dari analisis dan tingkat variabilitas dalam data paleontologi. Selain itu, cangkang yang teridentifikasi dapat digunakan sebagai referensi untuk perwakilan taksonomi Sangiran dan moluska di lapisan Kalibeng dan Pucangan Cekungan Solo di Jawa Tengah. Abstract. This paper is an update of fossil shell assemblages of Sangiran in Central Java. It is aimed to document and present the gastropods and bivalves from the Upper Kalibeng and Lower Pucangan series of the Sangiran dome from the Plio-Pleistocene period. There are 61 mollusc taxa recorded up to the genus level. Information gathered from mollusc assemblages are determined by the geological and environmental history of the Sangiran. They are associated with different facies: a) massive marls and blue clays, b) layered clayey limestone, c) silty gray clay, d) volcanic breccia and lahars and e) black clays, and composed of sediments representing marine to swampy environments leading to continental development. The quantitative patterns recorded in mollusc assemblages elucidate the palaeoenvironment and the relationship between the established palaeodatasets of analysis and the levels of variability in palaeontological data. Moreover, the identified shells may be utilized as a reference for Sangiran and molluscan taxonomic representative in Kalibeng and Pucangan layers of Solo Basin in Central Java.
