Abstract

Geothermal features can be observed in areas of active volcanism, or areas that have inactive volcanoes. In non-volcanic areas, the temperature of rocks within the Earth also increases with depth. This temperature increase is known as the Geothermal Gradient. If water percolates deeply enough into the crust, it comes into contact with hot rocks and can circulate to the surface to form hot springs. The collection of field hydrothermal data during field study with the help of portable instruments. The different physical parameters of the thermal springs such as temperature, pH, colour, and odour of thermal fluid are noted. The temperature of the thermal springs ranges from 43oC to 48oC. The pH value of the thermal waters shows a neutral (pH 6-6.6) and sulphur odour is discernible particularly. Based on geological, the system geothermal energy that develops is geopressured.

Abstract

Daerah panas bumi Waesekat termasuk dalam wilayah Kecamatan Kepala Madan, Kabupaten Buru Selatan, Propinsi Maluku. Jenis manifestasi berupa mata air panas bertemperatur sekitar 90°C dan batuan malihan. Morfologi sekitar manifestasi berupa satuan morfologi perbukitan dengan ketinggian 300–1500 mdpl. Identifikasi struktur bawah permukaan menggunakan metrode gravitasi / gaya berat. Metode gravitasi adalah salah satu metode geofisika yang digunakan untuk mengukur variasi percepatan gravitasi bumi akibat perbedaan rapat massa antar batuan.Dari data yang diperoleh di sekitar Waesekat terdapat anomali tinggi di sebelah Barat Daya daerah penelitian, dan rendah di sebelah Timur Laut. Potensi panas bumi diduga berada di daeah Timur Laut yang nilai anomalinya rendah. Berdasarkan korelasi dengan data geologi, struktur bawah permukaan, daerah ini tersusun atas serpih, batu pasir dan batu gamping.

Abstract

Foraminifera fossils will provide information on the relative age and depositional environment in the rock layers. foraminifera Fossil itself consists of two types, plankton and benthic foraminifera, which in a rock cannot be determined easily. Required methods are used to be able to decipher fossil foraminifera in the rock bodies. This method is called microfossil preparation. The precision in the execution process of the preparation will be very helpful in the process of further analysis of the fossil, which is the stage of determination. This stage will determine genus to species (taxonomy) of an organism based on the characteristics of each foraminifera. Each of the characteristics of foraminifera will show a unique tendency, both in the habitat when the organism is still alive until it can undergo fossilization.
