Secara geologi, wilayah Cekungan Bandung tersusun atas lapisan endapan danau purba yang rentan terhadap risiko gempa bumi. Dengan demikian, pengetahuan mengenai potensi likuifaksi di wilayah ini sangat diperlukan untuk mengurangi risiko gempa bumi. Makalah ini menyajikan hasil evaluasi potensi likuifaksi dan penurunan tanah akibat likuifaksi dengan menggunakan metode uji penetrasi konus (CPT) dengan mempertimbangkan gempa bumi dari zona Sesar Lembang (Mw 6,5) dan zona subduksi selatan Jawa (Mw 7,0). Berdasarkan skenario gempa bumi tersebut, penurunan tanah total sangat bervariasi disebabkan oleh perbedaan ketebalan lapisan pasir lanauan di setiap lokasi. Mempertimbangkan perbedaan percepatan tanah puncak, penurunan tanah total akibat gempa bumi dari zona Sesar Lembang akan lebih tinggi dibandingkan dengan penurunan tanah total akibat gempa bumi megathrust di selatan Jawa. ABSTRACT - Liquefaction potential analysis in Bandung Basin area using cone penetration test method Bandung Basin region is geologically composed of ancient lake sediments that are susceptible to earthquake risk. Therefore, knowledge of the potential for liquefaction in this region is needed to reduce the risk of earthquakes. This paper presents the results of the evaluation of the potential for liquefaction and ground settlement due to liquefaction using the CPT method by considering earthquakes from the Lembang Fault zone (Mw 6.5) and the southern Java subduction zone (Mw 7.0). Based on the earthquake scenario, the CPT locations will have a different liquefaction potential and total ground settlement due to differences in the thickness of the silty sand layer at each location. In an account of the difference in peak ground acceleration, the total ground settlement due to earthquakes from the Lembang Fault zone will be higher than that caused by the megathrust in southern Java.

Abstrak Longsor termasuk bencana alam yang sering terjadi di Jawa Barat. Banyak penelitian mengenai longsor. Salah satu penelitian didasarkan pada faktor penting pemicu terjadinya longsor yaitu pola curah hujan. Penelitian dilakukan di Lembang-Bandung sebagai daerah berpotensi longsor dengan menggunakan metode geologi teknik berupa uji karakteristik keteknikan tanah. Hasil dari karakterisasi keteknikan tanah berupa distribusi ukuran butir, porositas, permeabilitas, kohesi, dan dengan dilengkapi geometri lereng potensi longsor digunakan untuk mengidentifikasi besaran yang digunakan untuk mengetahui jarak jangkauan (run-out) longsor berdasarkan model gesekan Coloumb sederhana. Perubahan pola curah hujan yang dilakukan yaitu 0 mm/jam, 0,1 mm/jam, 5 mm/jam, 10 mm/jam, 20 mm/jam, dan 25 mm/jam menghasilkan stabilitas lereng (baca: faktor keamanan) yang berbeda-beda. Pola hujan ringan â€“ sedang menunjukan bahwa lereng berada dalam keadaan kritis dengan FK ~1,001 sedangkan saat hujan lebat â€“ sangat lebat menunjukan lereng berada dalam keadaan tidak stabil dengan FK< 1. Hal ini berpengaruh pada run-out longsor beserta kecepatan tanah. Semakin tinggi tingkat curah hujan maka lereng akan semakin tidak stabil sehingga tinggi awal pusat massa berubah menjadi lebih tinggi maka run-out longsor dan kecepatan pun semakin tinggi. Kata-kata kunci: Pola Curah Hujan, Faktor Keamanan, Jarak Jangkauan (Run-Out) Abstract Landslide is one of the most frequent natural disasters in West Java. There is a lot of research conducted under landslides discussion. One of the researches was conducted based on one of the important factors that trigger landslides that is rainfall patterns. The research was conducted in Lembang, Bandung as it is an area potentially having landslide. The method used was geological method particularly using engineering characteristic such as the soil test. The results of engineering characterization of soil are in the form of grain size distribution, porosity, permeability, and cohesion. It is completed by potential landslide slope geometry in order to identify the unit used to determine the run-out of the landslide based on the friction model of simple Coulomb. Changes in rainfall patterns made is 0 mm/h, 0.1 mm/h, 5 mm/h, 10 mm/h, 20 mm/h, and 25 mm/h resulting different intensity of slope stability (read: safety factor). That are light-medium rainfall pattern then the value FK ~ 1.001, while heavy-torrential rainfall pattern then the value FK <1. It affects the run-out landslides including the ground speed. The higher of the rainfall level, the lower of the slope stability will be, It increases initial high center of mass and also resulting the higher of the run-out of landslides and it speed. Keywords: Rainfall Patterns, Safety Factor, Run-Out

Abstrak Kompleksitas struktur pori terhubung pada sampel digital medium berpori 2D telah dianalisis menggunakan parameter tortuositas. Jalur pori terhubung dilacak dengan menggunakan Simple Neurite Tracer. Metode pelacakan dan perhitungan tortuositas tersebut diujikan pada lima model sederhana yang menunjukan perbedaan tingkat kompleksitas yang signifikan. Metode analisis kompleksitas tersebut kemudian diterapkan pada sampel medium berpori berupa citra digital batuan berukuran 560 Ã— 393 piksel, dan tanah berukuran 560 Ã— 475 piksel. Citra digital sampel tanah dan batuan yang dianalisis berupa irisan 2D pada bidang z-y (sagittal) yang diambil dari sampel 3D hasil pemindaian menggunakan -CT Scanner SkyScan 1173. Pelacakan jalur pori terhubung pada sampel model maupun sampel digital 2D batuan dan tanah yang menggunakan Simple Neurite Tracer menghasilkan koordinat jalur pori terhubung yang kemudian digunakan untuk menghitung nilai tortuositas. Tortuositas dihitung dengan menggunakan definisi rasio antara jumlah total sudut keberlikuan jalur terhadap jarak antara dua sisi sampel yang saling berhadapan. Untuk 5 sampel model yang menunjukkan kompleksitas yang berbeda, diperoleh bahwa semakin kompleks struktur pori tersebut, maka semakin besar nilai tortuositasnya. Untuk analisis pada sampel digital batuan, nilai tortuositasnya yaitu 0,0392 sedangkan pada sampel tanah didapat nilai tortuositas sebesar 0,0431. Kata-kata kunci: simple neurite tracer, tortuositas, kompleksitas, medium berpori Abstract The complexity of the connected pore structure of 2D porous digital media samples has been analyzed using tortuosity parameter. Connected pore was traced using the Simple Neurite Tracer. The tracing method and the tortuosity calculation were tested on five simple models showing significant differences in complexity levels. The complexity analysis method was then applied on digital image of a rock sample with the size of 560 Ã— 393 pixels, and a soil sample with the size of 560 Ã— 475 pixels. Digital images of the rock and soil samples were analyzed on the 2D slices in the zy (sagittal) plane which were obtained from the scanned 3D samples using the Âµ-CT SkyScan 1173 Scanner. Connected pore tracing for both the 2D models as well as the rock and soil samples was done using the Simple Neurite Tracer which produce the coordinate of the connected pore path which is then used to calculate the value of tortuosity. Tortuosity is calculated by using the definition of the ratio between the sum of the curvaceous angles of the connected pore path to the distance between two facing sides of the sample. For 5 sample models with distinctive complexity, it was found that the more complex the pore structure, the greater the tortuosity value. For analysis on digital samples of rocks, the tortuosity is 0.0392 whereas in the soil sample, the tortuosity is 0.0431. Keywords: simple neurite tracer, tortuosity, complexity, porous medium.

Fracture plays important role in oil, gas, and geothermal reservoir because it is easier to flow the fluid than the porous medium that form of granules. Fracture intensity is one of the main parameters of fracture that indicate the number of fracture at any length or section. Previous studies of fracture intensity calculation are limited to 2D fracture, the determination of 3D fracture intensity is still not comonly found because its determination method still slightly. Therefore, in this paper we/ve applied skeletonization method to 3D rock fracture. Skeletonization is thickness transformation of sample image composer that represented by the color white in the image (pixel with â€œ1â€ value in the binary image) into a new image with the thickness of white is 1 pixel. Skeletonization usually used to characterize the length of binary image in digital image analysis. Rock fracture sampel in this paper were drawn for Kamojang Geothermal Area in cube form with side 3.5 cm. The sample has been applied in 3 different temperature condition i.e. room temperature (24Â° C), 300Â° C, and 600Â° C. The fracture intensity which has calculated in each temperature condition respectively are 2.995Ã—10-3 cm-2, 3.160Ã—10-3 cm-2, and 3.850Ã—10-3 cm-2. These result indicate that the increasing of temperature not only make the new fractures, it also causes the propagation of old fractures so that fracture intensity increases. These result are appropriate with the thoery of temperature effect on forming fracture. Thus, skeletonization method can be an alternative for calculation of 3D fracture intensity. Keywords: fracture, binary image, skeletonization.

Digital image analysis has been done on rock samples of scanning results using Bruker Skyscan 1173 Micro-CT Scanner. The analysis is done qualitatively and quantitatively to know the characteristics of the sample image of the rock. The digital samples of rock produced from the scanning process are 380 x 380 x 380 pixels in size. Qualitative analysis is done by using CTAn (2D) and CTVox (3D) software. Quantitative analysis is done by calculating pore size, open porosity, closed porosity, total porosity and fractal dimension using CTAn software. The consensus analysis of the use of Cartesian axes of digital data in the software used (CTAn, CTVox, DataViewer, ImageJ and Matlab) is done by examining 2D trans-axial imagery (XY), sagittal (field ZY), and coronal (XZ). The results of the rock parameters analyzed in the rock samples indicate that the rocks belong to the type of faneric/fine fanerokristalin, have a porosity that is special, the pores in the rock are well connected, and the fluid flow in the rock is quite complex. Rock samples obtained from various software show similarities of image on CTAn, CTVox, and DataViewer software, but unlike the image of ImageJ and Matlab so it is necessary to change the coordinate axis if in advanced processing using both devices. Keywords: digital image analysis, porosity, fractal dimension, porous media

Porous rock composed of solid material and pores. Rock quality can be determined by various aspects as porosity, specific surface area and permeability which are affected by the size of grain occupying space on the rock. Rock model was then done by random penetrable sphere packing method which represent the simplest form of rock. Porosity is the ability to reserve, meanwhile permeability is the ability to deliver fluids without wrecking the rock structure. Specific surface area is the ratio of surface area with material mass or volume. The greater the variety of grain used, the smaller the value of porosity and permeability are, because of the rock spaces occupied will be larger. Thus, the value of specific surface area will increase. Keywords: porous rock models, porosity, permeability, specific surface area

Differences in the distribution of grain size (sorting) in porous rocks can affect the fluid flow complexity even though they have the same porosity. It can be analyzed by performing simple modeling that assumes granules can be represented in perfect overlapping, rounded forms. Rock models can be made by setting the main parameters of the granular radius until the desired porosity is reached. From the model made, the fluid flow complexity can be analyzed by using the tortuosity parameters in the x, y, and z directions of the rock model. Tortuosity is calculated as a comparison between the flow traces passing through the pores connected to the length of the side in the direction of the rock model flow, and trace flow tracking is done by the full random walk cubical method. In measuring the fluid flow complexity in this rock, porosity is made equal to three models, which is 15%. Porous rock models are arranged by placing the grains of varying radius (small, medium, and large) that are randomly distributed and overlapping in a 200 x 200 x 200 medium. From the results of calculations performed tortuosity values do not provide a specific pattern for the three samples in three different path tracking directions. This indicates that the medium with porosity can have diverse and anisotropic complexities. Keywords: porous distribution, tortuosity, complexity of fluid flow, model of porous rock
