Earthquake July 18, 2016 at 5:59:00 am occur on land 18 Km Northwest Purworejo. The earthquake measuring 3.6SR at a depth of 13 kilometers and was felt in Purworejo I - II MMI. This study aims to analyze the earthquake affected based on shakemap analysis and determine the type of fault used the initial motion of P waves that recorded on seismograph. Shakemap analysis using shakemap application at BMKG servers based on the accelerograph network BMKG. Meanwhile, an analysis the type of fault using focal application with data input signals from the seismograph SeisComP3 system. The highest values…
Telah digunakan banyak metode untuk mengkaji permasalahan longsor dari sudut pandangan pendekatan satu-disiplin, interdisiplin maupun multidisiplin. Beberapa metode sedang dikembangkan untuk dipadukan dalam investigasi longsor selama dekade terakhir ini, fokus studi diarahkan menggunakan pendekatan investigasi multidisiplin seperti survei geolistrik, geoteknik dan geokomputasi untuk menentukan potensi longsor sehingga dapat meminimalisir bencana longsor. Hasil kajian memberikan bidang gelincir terletak pada kelompok resistivitas menengah dengan jenis pasir atau pasir lempungan yang menindih ke…
Nanoparticles of magnetite (Fe3O4) have been successfully synthesized by coprecipitation method by mixing FeSO4.7H2O and FeCl3.6H2O with the addition of 10% NH4OH as kopresipitan. Then, functionalized Fe3O4Â concentration variation silica (SiO2) 5%, 10%, 15%, 20%, 30% and 50%. Particle size and magnetic properties of Fe3O4 nanoparticles were tested by X-Ray Diffraction (XRD) and Vibrating Sample Magnetometer (VSM). XRD results showed the addition of silica is not found new phases when added SiO2that serves as a template. The particle size of Fe3O4 nanoparticles obtained 14.23 nm, while the …
Penelitian ini menganalisa kedalaman air tanah dalam dengan mengunakan survai geolistrik yang terletak di sisi barat Kabupaten Grobogan, Jawa Tengah, Indonesia. Terdapat empat lokasi survai yaitu Desa Brabo dan Desa Padang (Kecamatan Tanggungharjo), Desa Deras dan Desa Padas (Kecamatan Kedungjati). Konfigurasi Schlumberger digunakan dalam survai geolistrik ini dengan bentangan elektroda arus sampai dengan 600 meter. Diperoleh kedalaman potensi air tanah dalam pada kedalaman antara 50 â 105 meter. Hasil ini sesuai dengan peta cekungan air tanah Kabupaten Grobongan.
Barium Strontium Titanate (Ba1-xSrxTiO3) or BST has been synthesized using solid state reaction method. Raw materials of BST were BaCO3, SrCO3, and TiO2. Those materials were mixed, pressed, and sintered at temperature 1200oC for 2 h. Mixing time of raw materials was varied to identify its effects on crystal structures and dielectrics constant of Ba0.9Sr0.1TiO3 using X-Ray Diffraction (XRD) and LCR meter instrument, respectively. The results of XRD showed that crystals structure of Ba0.9Sr0.1TiO3 is tetragonal. Lattice parameter of Ba0.9Sr0.1TiO3 for 6 h of mixing time is a = b = 3.988 Ã an…
The spectral analysis of surface waves (SASW) is an in situ non-destructive method. It has been developed and used for many years in the fields of geotechnical engineering and site characterization. It is typically used in evaluation of elastic moduli and layer thickness of soils, rocks and pavements.In this study the SASW was used to measure an attenuation coefficient (α) of near surface material at 15 development sites with different material e.i. soils, granite and methamorphics rock.. The attenuation coefficient which is the exponential decay constant of the amplitude of …
Based on the observations in SMP Negeri 2 Pandak, it was found that the activity and spirit of students in learning activities were low. The student oral was low and the quality of student learning was under the minimal completeness criteria. The aims of this research were to improve students learning outcomes of cognitive aspects, affective aspects of students andpsychomotor aspects of students after attending a t inquiry practice learning model. Design research is a classroom action research (CAR), which consists of 3 cycles. Subjects in this study are students of class VII-D …
The interaction of two nucleons in the form of protons and neutrons as a bound system in the local potential, known as the deuteron, has been investigated. Two-nucleon interaction potential field through the core will produce a nuclear force where the force between nucleons is generated by the exchange of mesons. One of the members of the group of meson particles is pion. Pion can be chargedï¨Ï + ,Ï -ï©or neutral,ï¨Ï 0ï©. Interaction potential form of the simplest is the exchange of one pion potential (OPEP), V OPEP , which has a radially independent of …
The numerical simulation for calculating the cross section of fusion reaction is done by using Wong formula. We especially calculated the cross section for the fusion reaction of light systems, i.e. 12C+12C, 16O+12C and 16O+16O reactions. We compared the obtained cross section with experimental data. In order to check the accuracy of the calculations, the chi-square analisys is then permormed. We found that the simulation results of the fusion cross section obtained using Wong Formula well explain the experimetal data of the fusion cross section for the 12C+12C, 16O+12C and 16O+16O reactions. …
The image of subsurface with a migration method keeps on developing to get an image result which the closest in real condition. The conditions in subsurface are very complex and variables it couses the process of wave propagation which can not be judged as the same in every layers. so it is needed an anisotropy pharameter analysiz (η) in seismic data migration process. The research will compare two kinds of migrations those are Kirchhoff migration and finite difference anisotropy. It is done because not all datas are processed by anisotropy, even with isotropi it will get good result. T…
Penyakit Jantung menjadi salah satu pembunuh terbesar dalam beberapa tahun terakhir baik di Indonesia maupun di dunia. Khususnya di daerah Malang Raya, lebih dari 34% dari jumlah pasien yang berobat di Rumah Sakit se-Malang Raya merupakan penderita penyakit jantung pada tahun 2011.
