Abstract

Research has been carried out using a magnetic method that aims to interpret the subsurface structure of the area hot springs Derekan - Diwak based on the total magnetic field anomaly data. It also aims to investigate the geothermal system in the area.Some 99 points measurement areas were measured using PPM (Proton Precession Magnetometer) geometrics type GSM19T models to get the value of the total magnetic field and two points as a base station simultaneously measured using the PPM G856X models. Measurement data is processed by the daily variation correction and IGRF (International Geomagnetic Reference Field) correction. The data has been used to create a contour corrected total magnetic field anomalies and subsurface cross sections involving the upward continuation and reduction to the poles.The results of study showed the total magnetic field anomaly closure pair of positive and negative closure indicate a fault zone below the surface. Interpretation is strengthened by the results of the modeling showed two faults of Derekan - Diwak areas trending southwest- northeast. This fault zone is a media outlet fluid to the surface in the area of geothermal systems.Keywords: geothermal, fault, and total magnetic field

Abstract

The climatic chamber is a calibration medium for the thermohygrometer. This simple climatic chamber was built using the Arduino uno, DHT22 sensor, heater, and peltier. The climatic chamber was designed and manufactured well and cheaply. Climatic chamber testing of the design results is carried out to determine the success rate of the tool. Tests are carried out using the Madgetech data logger tool through monitoring or monitoring of temperature within a certain period of time. The results of temperature monitoring at two observed values, namely temperatures of 250C to 300C and temperatures of 300C to 350C, showed good results with the corresponding rhythm of temperature increase and temperature decrease. It's just that the decrease in temperature still takes longer than the increase in temperature. This shows that the heater can be said to be working optimally and the peltier is not fully working. So it is necessary to do further studies related to the peltier for the climatic chamber both in terms of number and characteristics.
