Abstract

Research has been done on the spread of contaminants in the Supit Urang landfill, the city of Malang. The research was done in April 2013 - January 2014 in the area around Supit Urang landfill. The research purpose to determine the presence of contaminants in the Supit Urang landfill and distribution patterns. This research was begun by doing a data correction, consists of diurnal correction and IGRF correction so that got the total magnetic anomaly. Then, did reduction to the pole and upward continuation so that got the residual magnetic anomaly value ranging from -800 nT to 1100 nT. The results of data processing showed that contaminants in Supit Urang landfill accumulated on the inside of the landfill and then spreads in all directions with a depth of seepage reaches 25 meters. The spread of these contaminants are more inclined to the south because there is a river which is the discharge path of leachate from landfill to the river in the area. The results also showed the structure of the subsurface Supit Urang landfill dominated by sedimentary rocks such as sandstone, clay, tuff, tuff breccia and breccia. Based on the chemical test results, it showed contaminants in landfill is suspected to be leachate with susceptibility value between 0.0001 Wb/Am to 0.001 Wb/Am. Leachate from landfill contains some heavy metals with different concentrations, such as Cobalt (Co) 0.38 mg/L, Copper (Cu) 0.58 mg/L, Iron (Fe) 6.5 mg/L, Lead (Pb) 5.4 mg/L and Zinc (Zn) 4.8 mg/L.

Abstract

The process of volcano research through visual monitoring usually takes a long time.  There is many time possibility of  an occurance of a specific volcano phenomena such as lava and plum. The problem with this monitoring activity can be helped through visual monitoring system that enables constant recording and automatically detects events that can be observed through the visual volcano object. This monitoring system works through an event detection application with static object definitive, fixed focus definitive and sensing area definitive combination method that forms a simple yet effective method called Motion Range Event Detection. This method is a form of volcano object monitoring using camera sensors by defining the form of volcano object as a static object and defining the object phenomena changes based on a predetermined area.

Abstract

Geothermal energy is a source of heat that occurs naturally in the subsurface. One of the geothermal potential in East Java is in the Blawan that known as geothermal Blawan - Ijen. To find a geothermal potential of an area we have to do some research on subsurface conditions. Research using geoelectric resistivity method has been performed to estimate the distribution of hot springs. The study, conducted in May 2013 showed that there are 21 hot springs manifestations in Blawan - Ijen. Each of these hot springs have a temperature less than 50 °C. Data of geoelectric resistivity divided into 3 parts, resistivity values less than 40 ohm.meter indicated by the color blue , the color green for the resistivity value between 40-1280 ohm.meter and the color orange for values more than 1280 ohm.meter. Geothermal distribution that contained in Blawan is diffused follow existing fracture. Direction of hot springs are heading to the Northeast that following the river flow. The heat carrier layer is permeable layer that have resistivity values less than 40 ohm.meter.

Abstract

Volcanic tremor is one of the most important volcanic activities due its strong connection to magma movement and impeding eruption. Therefore, the determination of volcanic tremor epicenter becomes very important. The absence of apparent P and S wave arrival of volcanic tremor is the main constraint of its epicenter determination. The use of semblance method is required because semblance method requires no information about P and S wave arrival in epicenter determination. A preliminary application of semblance method has been done to determine the epicenter of 100 s length volcanic tremor of Sakurajima volcano. In this research we use the recorded seismic signal from 5 different volcano observatories, which are KOM, KAB, HIK, ARI, and HAR. The recorded tremor signal is then analyzed by using semblance method. The analysis is carried out by calculated semblance coefficient in every 30 s moving window along the signal. The resulting semblance coefficient varied from 0,25 to 0,42. The epicenter of observed volcanic tremor is located in the north-east part of Minamidake crater by -18,66o to 54,10o of azimuth counted from the east, while the epicentral distance of the observed volcanic tremor varied from 608,28 to 948,68 m from Minamidake crater.

Abstract

Bromo volcano is one of a series of active volcanoes in Indonesia, located on the Tengger caldera, Probolinggo, East Java. Bromo volcano has increased volcanic activity in the end 2015 until early 2016. The research was conducted to determine the characteristics of volcanic tremors. The methods used to determine the characteristics of volcanic tremors are spectral analysis and cross-correlation waveform analysis. Spectrogram analysis obtained frequency value 1-8 Hz for volcanic tremor of Bromo Volcano. From the results of spectral analysis volcanic tremor, it’s can be seen the value of the frequency peaks irregular means the type of spasmodic tremor. Based on the pattern of the peaks of the tremor spectral analysis using 3 stations having the same pattern and the analysis of cross-correlation waveform volcanic tremor of Bromo volcano was indicated from the same source mechanism because the correlation coefficient value is good that ranged about 0.6 – 0.8.

Abstract

Pulung Region, Ponorogo major city, Indonesia is one of the area in Indonesia which is prone of the local earthquake threat. Since 1963, there was about 7 big earthquakes, where 1 earthquake was destroyed earthquake and 2 events occured at the Pulung region. The two those earthquakes occured at Pulung were in 1993 and 1999, with the magnitude was 3.7 SR  and 5.6 SR respectively. The last event was on February 2011, therefore it’s necessary to study and determine the  seismicity. In addition the relocation analysis using Grid Searching seismicity showed that the distribution of earthquakes shifted to the East direction, with the coordinat of from  7.8122º to 7153º SL and 111.6360o to 111.7303° EL, the depth of earthquakes varies between 0.532 km and 7250 km, and the magnitude was between 1.4 and 2.0 SR. It is hoped that this result can be used for the govermnment of Ponorogo to mitigate of earthquake impact.
