Gravity method is a method used to find the difference of gravity value from one point to another in a place caused by mass distribution which is below the surface of research area. Basement identification of complete Bouguer anomaly data has been done in the Timor Basin with geographical position 9.40 LS – 10.40 LS dan 123.50 BT – 125.40 BT. The identification of the basement under the Timor Basin is based on gravity field anomaly data. The gravity field anomaly data used in the research is the result of measurement of Geodetic Satellite and European Remote Sensing Satellite which has been corrected to free air correction. Based on the inversion, the overall average density from the first layer to the tenth layer 2.662 . Timor Basin which is a place of accumulation of sediment and has a basement which is a type of metamorphic rocks from within 3.86 km to 20 km strong and is not pass the water hence this basin has the potential of a trap of natural energy sources in the form of oil and gas.

Bio-briquette is one of the fuels that comes from biomass. The biomass used in this research is coconut shell and rice husk. The aims of this research are to know the influence of variation of rice husk composition and thickness variation on physical parameters of shell briquettes. The results of this study indicate that the density, moisture value, porosity and ash values, respectively ranged between (0.69 - 1.12 ), (3,33% - 7,57%.), (16,66% - 31,88%.), (38,46% - 66,66%.). The analysis showed that in general, the composittion of rice husk is inversely proportional to density, moisture value and briquette ash value, otherwise the composition of rice husk is directly proportional briquette porosity value. Based on density value, mositure value and ash value it can be concluded that in this research the quality of briquettes with composition 40% coconut shell and 60% rice husk is better than the other compositions.

A human body mass index measurement system has been developed by using IR sharp distance infrared cencorG P2Y0A02YK0F,200 kg Load Cell, Arduino Uno,Raspberry PI 3,HX711, HDMI display and the other electronic components. In this research Arduino Uno has a purpose as the instruction center with AT Mega 328 microcontroller is used to prosess high measurement data and body mass obtained from cencor Sharp IR GP2Y0A02YK0F dan Load Cell. This measurement system is controlled by the Arduino programming language. After Arduino Uno get a high data and body mass, the data is sent to raspberry pi 3 to calculate body mass index value ( BMI ) and the body category determination using lazarus programming language. If the BMI value < 17,0 classified as “very thin” body category, the BMI value between 17,0 – 18,4 has the category of “ thin body “, the value of intermediate BMI 18,5 – 25,0 has the “ normal body “ category, BMI value between 25,1 – 27,0 has a “ fat body “ category, and a BMI value >27,0 has a “ very fat body “ category. Raspberry pi 3 is also aquipped with HDMI support, hence all high data mass, BMI and body category will be displayed on HDMI monitor as its output.

The research using HVSR (Horizontal to Vertical Spectral Ratio) has been carried out to map the disturb areas to earthquakes in Bitobe village. The aims of this research are to determine the values of soil dominant frequency and the peak ground acceleration than make PGA map and also microzonation map. Data were collected at 45 points with the distance between points ± 250 meters from one point to the other with ± 20 minutes of recording time used TDS 303S type. The data were processed using software Datapro, Geopsy, Surfer 13, and Google Earth. The result of data processing was dominant frequency value (). This parameter was used to calculate the peak ground acceleration with Kanai empirical equations. The earthquakes catalog data were used from 1966-2016. Mc.Guirre and Esteva method only used the earthquakes catalog data to calculated the PGA. According to this research, it was obtained that the values of the dominant frequency was about 0,273 Hz – 17,887 Hz. The values of peak ground acceleration based on Kanai empirical equations about 32,319 gal – 261,178 gal, Mc.Guirre about 128,215 gal – 134,862 gal and Esteva about 147,359 gal – 156,007 gal. The result of this third equations have different with the earthquakes hazard map of Indonesia.

Geophysical research by using the gravity method has been carried out on the Ranakah child mountain and surrounding areas in Manggarai Regency of East Nusa Tenggara in June until July 2016. This research aims to know the condition of the subsurface geology of the area of research using the free air anomaly data from Sandwell and Smith 2016. The data are reduced by atmospheric correction, Simple Bouguer correction, and the correction of curvature to obtain complete Bouguer anomalies.
