Abstract

Temperatur merupakan aspek penting dalam sistem panas bumi untuk pengembangan panas bumi sebagai sumber energi. Penelitian ini dimaksudkan untuk mengetahui jenis litologi, mineral alterasi, tipe dan intensitas alterasi serta penyebarannya pada sumur X, dan bertujuan menentukan temperatur berdasarkan geotermometer mineral yang kemudian dibandingkan dengan data hasil pengukuran temperatur (T) sumur. Objek dalam penelitian ini berupa serbuk bor (cutting) dari sumur X yang dianalisis dengan metode petrologi, petrografi, dan XRD. Hasilnya menunjukkan, bahwa litologi sumur X terdiri atas andesit terubah, tuf litik terubah, dan tuf kristal terubah. Mineral alterasi yang berkembang didominasi oleh mineral alterasi dengan pH netral yang berupa kuarsa sekunder, kalsit, epidot, montmorilonit, illit, smektit, klorit, oksida besi, dan pirit, serta beberapa mineral ber-pH asam seperti kaolinit, kristobalit, anhidrit, dan haloysit. Berdasarkan asosiasi mineralnya, alterasi pada sumur X dibagi menjadi tiga tipe, yaitu alterasi argilik dengan perkiraan temperatur antara 150oC hingga 180oC, alterasi subpropilitik antara 150oC s.d. 220oC, dan alterasi propilitik antara 210oC s.d. 280oC. Secara umum, hasil geotermometer mineral ini menunjukkan data temperatur yang lebih tinggi dibandingkan data T berdasarkan pengukuran sumur.

Abstract

The presence of geothermal manifestations in the form of hot springs is closely related to the presence of permeability zones in the Sumani geothermal system, West Sumatra. The permeable zone allows fluid circulation where meteoric water seeps to fill the reservoir and emerges on the earth's surface as a manifestation of hot springs. This study aimed to identify those permeable zones based on lineament density analysis using the Fault Fracture Density (FFD) method on ASTER GDEM satellite imagery. Lineaments in this case was assumed to be associated with fractures or faults in geothermal areas. The method was used to analyze the presence of lineament on topographic maps and to clarify all lineaments in the study area by adjusting the irradiation angle of 0°, 225°, 270°, and 315° at a constant altitude of 45°. From the FFD method, high lineament density values were found in the southwest of the study sites. The pattern of lineaments in the research area had northwest - southeast and southwest – northeast. The FFD analysis results were compiled with location of geothermal manifestations and geomorphological analysis which then showed positive results on the emergence of dominant hot springs depending on zones with high lineaments density and was located in the pyroclastic flow geomorphology unit with a difference in elevation between 500-1500 masl and slope of moderately steep to steep; indicating catchment area. Further research was needed to accurately understand about reservoir and the potential of geothermal reserves in the Sumani area.Keywords: Sumani Geothermal System, Fault Fracture Density, Geomorphological Analysis.

Abstract

Planktonic foraminifera are widely utilized for marine sediments analysis and recent developments in the geochronology of planktonic foraminifera has improved their values as a tool for sedimentary basin analysis. Assessment on the applicability of the “standard” foraminiferal biozonations (e.g., Bolli, 1966; Blow, 1969; and Postuma, 1971) to the biostratigraphy data of the South Sumatra Basin suggests that the standard zones, which are mostly interval-zones defined by first occurrence events, are hardly applicable to the biostratigraphy data derived from the examination of well-cuttings routinely and continuously used in most sedimentary basin studies in Indonesia.The proposed biozonation in this paper were constructed based on two considerations, i.e. information on the biostratigraphy events as indicated in regional- and global-scale biozonation schemes and the occurrence of foraminifera species in the South Sumatra Basin. The correlation between the proposed zonation and that of Blow’s (1969) scheme suggests that the proposed zonation is basically a Blow’s zonation and, accordingly, may be perceived as a modified Blow’s zonation for South Sumatra Basin.

Abstract

AbstractThe Batu Hijau Mine is one of the biggest gold-copper producer in Indonesia which operated by PT Amman Mineral Nusa Tenggara (PTAMNT). The mine site is located in the southwest corner of Sumbawa Island in the Sunda-Banda Archipelago in Indonesia. Based on the tectonic plate perspective, the Sumbawa Island lies along the tectonically active rock sequences.Refers to the geological model from comprehensive study starting from the exploration up to exploitation stages, there are four rock types that formed the slope at Batu Hijau Mine, namely volcanic rock, diorite, tonalite and young tonalite. The volcanic rock as a host rock is the most dominant material among the other rocks type which expose on the north-west, west and south wall.This study was focused on determining of the index conversion factor of the relation between uniaxial compressive strength (UCS) and point load test (PLT) data which obtained from the laboratory test result. The correlation factor for predicting UCS value from the PLT data for each rock type has shown the good correlation with the average of regression value is 0.88.  Keywords : Batu Hijau, Uniaxial Compressive Strength, Point Load Test, Conversion Factor.
