Abstract

A study for delineating geothermal system of prospect area “P” has been done by using multi-dimensional modeling of magnetotelluric data. Physiographycally, geothermal prospect of “P” area is located at non-volcanic Banda inner arc hosted by Malihan Sekis rock complex with Perm-Trias age. The existance of geothermal system in this area is indicated by the presence of thermal manifestations in form of 6 chloride-bicarbonate hot springs with temperature in the the range of 37-67oC, and pH of 6-7. The development of geothermal system is most probably associated with strong tectonic activity caused by the collision between Seram island plate and Australian plate that ignite the occurence of intrussive body as heat source. In order to know the subsurface information of prospect area, magnetotelluric (MT) survey has been done. The processing of MT data was started from time-series data, continued by noise filtering, rotation of strike orientation and static shift correction to obtain better MT curve. The data were then being inversed by means of 1-Dimensional, 2-Dimensional and 3-Dimensional inversion methods. Reservoir temperature is estimated to be around 160-180 oC and classified as moderate temperature. The result of MT data inversions shows the presence of conductive layer (<15 ?m) with 500-1000 m thickness that is interpreted as clay cap og geothermal system. High resistivity zone (>300 ?m) with updome shape appears underneath the manifestations occurence (MAP1, MAP2, MAP4, and MAP5), indicating that the heat source is located in northern part and elongate to souteast direction. The conceptual model of geothermal system was built based on integrated interpretation of geological, geochemical and geophysical data. The prospect area and recommendation of drilling location is estimated to be ± 3 km2 around upflow zone.Keywords: Prospect zone, geothermal system, magnetotelluric method, multi-dimension modeling

Abstract

The electronic circuit engineering learning processes generally requires specific infrastructures which sometimes constrained to cost factors in the procurement. Circuit simulator could be an alternative as electronic circuit engineering learning tool. Architectural simulation provides designers the ability to quickly examine a wide variety of design choices. The recent trend in system design toward architectures that react to circuit-level phenomena has outstripped the capabilities of traditional cycle-based architectural simulators. In this paper, a simulator that incorporates a circuit modeling capability, permitting architectural-level simulations that react to circuit characteristics (such as latency, energy, power brightness, or current draw) on a cycle-by-cycle basis is presented. As for learning purpose, circuit template and pre-built circuits for many categories are provided. The environment enables process visualization and simulation of analog and digital circuits. The system enables the creation of many laboratory exercises, which offer students opportunities to follow visually characteristic processes in analog and digital circuits. At this research, Rational Unified Process (RUP) software process model and Object Oriented Programming (OOP) are implemented.Keywords: architectural simulation, circuit simulation, learning, RUP, OOP

Abstract

Research has been done with the title the effect of irradiation electromagnetic wave on the growth of green beans. This research has been done by taking data in the form of the height of green beans stems. The method used in this study is direct observation of the growth of green beans stems. The irradiation of the growth of green beans stems is divided into three types, with sunlight, mobile flashlight, and without irradiation. The results of the study showed that the growth of green beans stems irradiated by mobile flashlights was higher than the growth of green beans stems irradiated by sunlight. However, the green beans stems irradiated by the mobile flashlight are paler and easily shaky compared with the green beans that are irradiated by sunlight which looks fresher and sturdier. On the other hand, green beans that are not given irradiated, only grow a little buds and do not grow.Keywords: Vigna radiata, electromagnetic wave, sunlight, and mobile phone flashlight
