Asfar Maluašia: Mandejská kniha astrologie, lékařství a magie v novém světle
No full textThe Mandaean Asfar Maluašia was compared with other sources of Middle Eastern astrology and divination only in some cases. The old structure of this compilation suggested by Lady Drower is not sufficient for present studies and very important similar texts of Middle East were not mentioned in her translation. The author of this study proposes new structure and he points at the known astrological and divinatory writings with parallels of Asfar Maluašia. He also translates from Mandaic texts which are identified as Mandaean originals and reconstructs the original purpose and meaning of the compilation. Through study of its colophons the author traces the origins of Asfar Maluašia texts to the 17th century and the combination of separate texts to the 18th century. As the comparison proves, some of the contents of the Asfar Maluašia is actually much older and incorporates the Babylonian and Greek traditions – amongst them the Apocalypse of Daniel.The Mandaean Asfar Maluašia was compared with other sources of Middle Eastern astrology and divination only in some cases.

Rancangan Sistem Pembuatan Kapur Tohor di Desa Lakarinta Kabupaten Muna Provinsi Sulawesi Tenggara
No full textThe partner in this Community Partnership Program (PKM) was Lakarinta Village community group, especially the youth group who have businesses in making calcium oxide. Problem faced by partner was that so far the making of calcium oxide from burning limestone is done in an open space (influenced by outside air) using wood fuel taken in the surrounding environment. In this way, community group produced calcium oxide takes a long time because the process of burning limestone does not take place optimally due to heating which is heavily influenced by outside air. To overcome the problem of partner, the PKM Community Service Team designed a system of making calcium oxide with the aim of activities, namely : (1) The existence of an effective calcium oxide making system from the burning of limestone which could be used by the community group of youth groups to increase and accelerate the activities of calcium oxide production, (2) Increasing public knowledge about how to make calcium oxide through an effective limestone combustion system so that it can increase and accelerate the production. The method of implementing the activities were: socialization and field survey, the design of the calcium oxide-making system, trials, and discussions / questions and answers with partners. The results achieved were (1) partners have an effective calcium oxide making system (furnace using heating element / heat storage), (2) partners have knowledge in making calcium oxide through an effective limestone combustion system so as to increase and accelerate production activit
Profil Endapan Nikel Laterit di Kecamatan Tinanggea, Kabupaten Konawe Selatan, Provinsi Sulawesi Tenggara
No full textDaerah penelitian terletak di Kecamatan Tinanggea, Kabupaten Konawe Selatan, Provinsi Sulawesi Tenggara. Penelitian ini bertujuan untuk menentukan profil endapan nikel laterit di daerah penelitian. Metode penelitian yang digunakan terdiri dari studi pustaka, pengambilan sampel di lapangan dan analisis laboratorium serta interpretasi data. Hasil penelitian menunjukkan bahwa profil endapan nikel laterit di daerah penelitian terdiri dari tanah penutup (top soil), zona limonit, zona saprolit dan batuan dasar (bedrock) dengan ketebalan yang berbeda-beda. Tanah penutup pada Stasiun 1 sangat tipis berupa lempung dan sisa-sisa tumbuhan, sedangkan pada Stasiun 2 berupa lapisan sedimen (batu gamping) dengan ketebalan 0-5 meter. Berdasarkan data geokimia menunjukkan bahwa unsur/oksida Ni, SiO dan MgO menunjukkan pengkayaan pada zona saprolit karena mempunyai mobilitas yang tinggi sehingga mudah larut selama proses laterisasi dan tertransportasi ke arah bawah permukaan serta mengalami pelindihan sehingga terkonsentrasi pada zona saprolit. Adapun unsur Fe mempunyai menunjukkan pengkayaan pada zona limonit karena unsur Fe mempunyai mobilitas rendah sehingga tidak mudah tertransportasi ke arah bawah dan terkonsentrasi pada zona bagian atas yakni zona limonit.
The research area is located in Tinanggea District, South Konawe Regency, Southeast Sulawesi Province. This study aims to determine the profile of laterite nickel deposits in the study area. The research method used consists of literature study, field sampling and laboratory analysis and data interpretation. The results showed that the profiles of laterite nickel deposits in the study area consisted of top soil, limonite zone, saprolite zone and bedrock with different thicknesses. Top soil at Station 1 is very thin in the form of clay and plant remains, while at Station 2 it is a layer of sediment (limestone) with a thickness of 0-5 meters. Based on geochemical data, it shows that Ni, SiO and MgO elements /oxides show enrichment in the saprolite zone because have mobile so its dissolve easily during the laterization process and are transported the subsurface and experience leaching so that its are concentrated in the saprolite zone. The Fe element shows enrichment in the limonite zone because the Fe element has immobile so that it is not easily transported downward and is concentrated in the upper zone, namely the limonite zone

No full textAnalysis of Ultramafic Rocks Weathering Level Using the Magnetic Susceptibility in Konawe Regency, Southeast Sulawesi, Indonesia
No full textThe Konawe region is part of the Sulawesi Southeast Arm ophiolite belt where ultramafic rocks are exposed in the form of dunite and peridotite. The formation of nickel deposits is closely related to the weathering process of ultramafic rocks as a source rock. Ultramafic rocks exposed to the surface will experience weathering which is influenced by many factors, including in the form of climate change, topography, and existing geological structures.
The weathering process in the source rock can influence variations in chemical elements and magnetic properties in laterite soil profiles. For example, the chemical weathering might affect magnetic mineralogy and the physical weathering could affect granulometry as well as the quantity of magnetic minerals in the soil. Condition of weathering of ultramafic rocks (initial, moderate and advanced) can affect nickel content in laterite sediments. The weathering profile study of serpentine mineral is an indication of the lateralization process that occurs in ultramafic rocks and is carried out through petrographic analysis of thin cuts and polish cuts. Determination of weathering level like this is based on the level of weathering of the mineral serpentine.
In this study, the determination of the weathering level of ultramafic rocks (initial, moderate, and continued) uses magnetic susceptibility parameter. A total of 232 ultramafic rock core samples obtained from 34 hand samples were taken from different places and weathered levels were analyzed. The results of the research have shown that the magnetic susceptibility of ultramafic rocks in the study area varies, from 580 x 10-6 SI to 4.724 x 10-6 SI. Based on the value of magnetic susceptibility, magnetic minerals contained in ultramafic rock samples are hematite and geotite minerals. This means that the weathering level of ultramafic rock samples is the continued weathering level. The level of continued weathering that occurs in ultramafic rocks in the study area produces nickel laterite deposits with a nickel content of 1.65 - 2.40% in the saprolite zone, 0.42% in the saprock zone, and 0.20 - 0.51% in the basic rock zone (bedrock)
