Abstrak. Pengolahan data seismik merupakan suatu pekerjaan untuk menekan noise dan memperkuat sinyal dari hasil rekaman data lapangan. Supresi multipel dengan metode radon demultipeldan dekonvolusi prediktif adalah salah satu teknik yang biasa digunakan dalam penekanan energi multipel pada data seismik. Prinsip kerjanya adalah dengan memisahkan sinyal dan multipel dalam domain radon dengan memanfaatkan nilai perbedaan moveout antara sinyal primer dan multipel pada metode radon sedangkan pada dekonvolusi prediktif yaitu dengan cara mencari bagian-bagian yang bisa diprediksi dari trace seismik. Metode ini diaplikasikan pada data seismik laut 2D. Studi ini bertujuan untuk mengetahui respon dari metode dekonvolusi prediktif dan radon demultipel dalam mengatenuasi multipel pada pengolahan data seismik dan memperbaiki kualitas data rekaman sehingga menghasilkan penampang seismik yang bebas dari noise. Hasil yang diperoleh dari analisa metode dekonvolusi prediktif dan radon demultipelprediktif, data yang diperkirakan sebagai reflektor primer menjadi lebih menerus sedangkan untuk radon demultipel rasio sinyal terhadap gangguan data keluaran lebih besar dari pada data masukan, hal ini karena nilai multipel pada data seismik berkurang. Kata kunci: supresi multipel, radondemultipel, dekonvolusi prediktif

ABSTRACT. Seismic data acquisition is done to get a recording of seismic data. The quality of seismic data judged from a comparison between the amount of reflection signals received by signal interference received. Three-dimensional seismic survey (3D) provides an overview of the subsurface geology accuracy better than seismic two- dimensional (2D). Seismic three-dimensional (3D) generally require a higher cost than the two-dimensional (2D) because the density of the firing point and the receivers more. Making the seismic survey design into a solution of a problem before conducting seismic exploration for exploration which was preceded by design rarely meet with failure and have a positive impact in optimizing the configuration of the spread as well as aspects of the economy. Of the four designs seismic surveys that have been made and the discussions it was found that all the firing patterns, to the desired target has been able to meet the desired targets. Firing patterns have value slanted fold better than firing patterns orthogonal, brick, and the patch because it has a value greater fold. Firing patterns patch is firing patterns are more suitable for shallow penetration compared with the three other designs, but in terms of the cost will be more expensive. Of the four firing patterns that have been made can be concluded that the firing patterns of brick is more objective in terms of both data and the distribution of funds will be issued. KEYWORDS: seismic, seismic survey design, firing patterns

This research has been done in the mining area of andesite rock of Awang Bangkal village by using magnetic method. Magnetic method is one of the most common geophysical methods used for preliminary surveys on petroleum, earth, and mineral rock exploration. It is intended to determine the subsurface distribution in the area by performing qualitative and quantitative interpretations based on the magnetism value of the earth. The result of data processing using geosoft oasis montaj software shows that the total magnetic field anomaly is -807,3 to -361,7 nT. Qualitative interpretation is done by looking at the contour map of the anomaly, the result of upward continuation and the reduction to the poles. While the interpretation is done by making a modeling of the path that has been determined using mag2dc software. The model shows that the rocks that dominate the area are andesite rocks with their susceptibility value of 0.0992 to 0.2305 in SI units.

This research is conducted by using physical model and Lattice GasAutomata method for simple flow patterns having different geometry. Fromphysical model, the results are speed pattern and fluid flow permeability. Theresulted value of the permeability by using physical model will be compared tothe resulted value of the LGA. The compared value of the LGA method is thevalue with angle 5o, 10o and 15o by using laboratory scale. These angles arechosen due to it’s the lowest error compared to those of other angles. In thephysical model the lowest permeability value is gotten from the pattern of straightgeometry 60o with value 0.201 x 10-6 m2 and the highest permeability value isfrom pattern of turn 2 with value 0.341 x 10-6 m2. While by using LGA methodthe the lowest permeability value is pattern of straight 60o with value 0.209 x 10-6 m2 while the the highest real permeability value is pattern of turn 2 with value0.344 x 10-6 m2. From the comparison data of permeability the results of errorare 3.74%, 0.7% and 4.2% for the angle of 5o, 10o and 15o, respectively

ABSTRACT. Along with the increment of human population, ground water pollution also tends to increase. It primarily due to the accumulation of waste which could harm the public health. Trash or waste is one of the important issues which could contaminate ground water, especially waste landfills. Ground water that has been contaminated with liquid waste (leachate) can affect the quality of ground water. This study aimed to determine the composition of rocks, layers and depth of ground water around waste landfills (TPS) and to determine whether ground water around the TPS is contaminated or not. Estimation of groundwater pollution could be determined by measurement using geoelectric method with schlumberger configuration. It showed the presence of leachate layer at depth of 0,51 – 8,51 m with measured resistivity of 3,89 – 9,63 Ohm.meter, while groundwater is at depth of 22,92 – 26,59 m with resistivity value of 88,98 – 128,75 Ohm.meter. AAS sample test has been conducted to determine whether the ground water around TPS is contaminated or not. The test results using AAS showed groundwater around TPS was contaminated with Lead (Pb), iron (Fe) and Cadmium (Cd). The evidence was the value of their concentrations in three water samples which exceeded the thresholds in accordance with the requirements of drinking water. Threshold for Pb, Fe and Cd are 0,01 ppm, 0,3 ppm and 0,003 ppm, respectively. From the measurement results of sample 1, 2 and 3 couls be obtained the concentration of Pb are 0,084 ppm, 0,044 ppm and 0,091 ppm, the concentration of Fe are 0,812 ppm for 1,018 ppm and 0,203 ppm, while the concentration of Cd are 0,012 ppm, 0,017 ppm and 0,01 ppm. Keywords: Ground water, waste, geoelectric, AAS

ABSTRAK. Batubara merupakan solusi bagi kebutuhan sehari–hari karena harganya yang murah terutama bagi negara-negara dengan harga minyak yang terus naik, maka batubara dapat menjadi sumber energi primer. Penelitian ini dilakukan di PT.Telen Orbit Prima Desa Buhut Kapuas Kalimantan Tengah. Tujuan dari penelitian adalah untuk menentukan lapisan batubara di bawah permukaan bumi berdasarkan data well logging, menentukan karakteristik sebaran batubara di bawah permukaan dengan menggunakan metode cross section, dan melakukan interpretasi sebaran lapisan batubara untuk menentukan sumberdaya batubara. Lubang bor yang terbagi dalam 10 cross section akan dikorelasikan untuk mengetahui pola sebaran batubara dari ketebalan dan karakteristik pada seam batubara. Setiap lubang bor akan memberikan bentuk kurva log yang berbeda sesuai dengan kondisi masing–masing. Semua kurva log gamma ray yang ada kemudian diinterpretasikan untuk memberikan informasi mengenai batasan tiap lapisan litologi. Berdasarkan kurva log gamma ray, lapisan batubara memiliki ketebalan 0,5–8,2 meter, dari kedalaman 4,2–145 meter dengan elevasi yang berkisar dari 49,439–85,236 meter dengan jumlah sumberdaya 8.810.124 m3.Kata Kunci: Batubara, kapuas, well logging, cross section.
