Abstract

Public awareness of the benefits of honey has increased the amount of honey consumption. This encourages the circulation of impure honey in the market by irresponsible traders. Therefore, characteristic information of honey is needed as a basis for honey purity testing methods. Physical characteristics analyzed in this study are the refractive index, permittivity, density and color quantization of honey. In general, it can be seen that the higher the concentration of honey, the higher the refractive index and its density and inversely proportional to the permittivity. Color analysis also shows that concentration is inversely proportional to the color intensity level.

Abstract

As one of unique non-volcanic geothermal field in Indonesia, mapping the groundwater flow in Nyelanding Village, South Bangka is essential as preliminary study for further exploration activity if the geothermal manifestation. In order to achieve this goal, we conduct a research using natural electrical properties of subsurface, Self-Potentials (SP) method. In this study, fixed-based technique was used where the spacing between measurement stations is the multiplication of 10 m along three lines at the study area. Raw field data (potential value) was corrected to diurnal and closure corrections. Further, SP anomaly was plotted and combined with topography data to be analyzed. The result shows potential value raging from -25mV to 100mV which in agreement with the lowest and highest elevation in topography map, respectively. This means, these values are controlled by topographic feature in the study area. Thus, in conclusion, the groundwater flows from the West to North East and South East part of the study area

Abstract

Central Bangka is one area that has geothermal potential such as the Terak and Keretak area. These area have hot spring manifestation. Geothermal manifestations in Bangka is the type of non-volcanic radiogenic geothermal. Origin sources of this manifestation suspected from rocks run into the crack, folds and faults. The purpose of this study was to identify rock speading in geothermal area and it’s correlation between geothermal manifestation in Terak and Keretak. The data obtained from the TOPEX/Poseidon satellite is in the form of FAA (Free Air Anomaly) data. The data is then corrected using Burger correction and field correction. Spectral analysis was performed by Fourier transform with moving average filter. The results showed that Complete Bouger Anomaly has 13 mGal-39 mGal. Regional anomaly has 5,4 mGal - 9.8 mGal. Residual anomaly has 7 mGal sampai 29 mGal. There area was consist of intrusive granite rock from the Granite Klabat formation, clas and sandstone from Tanjung Genting Formation. Gravity anomaly shown Geothermal Terak and Keretak are composed of the same distribution of rock.
