<![CDATA[Resolution capability of seismic reflection data is becoming more interesting topic to discuss even for today. Several methods and approximations to attempt bandwidth extension of seismic reflection data have been proposed in wide variety. Among them is a non-stationary reflectivity inversion based on basis pursuit decomposition technique. The need of the method is increasing as it can provide realistic resolution of seismic data. The main advantages of the method are consistancy with log data, good lateral continuity, preserve amplitude and capable in denying artificial reflection feature. Nevertheless, its computational process is very expensive thus most pratitioners tend to avoid the method and look for another method that could serve quicker instead of better results.This paper attempt to propose a set of computational scheme which can be used flexibly for any prospective user to reduce the computational cost of the method.]]>

<![CDATA[Magnesium Ferrite Magnesium (MgFe2O4) magnetic nanoparticles have been successfully carried out by varying the concentrations of PEG-4000 and silica as encapsulation materials using coprecipitation methods. The X-ray Diffraction (XRD) analysis showed that new phases appeared in MgFe2O4 after PEG-4000 encapsulation, ie α-Fe2O3 having a paramagnetic rhombohedral and γ-FeO (OH) structure. The particle size of MgFe2O4 before encapsulation was 10.5 nm, after encapsulation with PEG-4000 became 5.2 nm and encapsulation with silica became 18.8 nm. In encapsulation with silica, the peak of the new diffraction field 222 which is a crystal appears. The result of Fourier Transform Infra-Red (FTIR) analysis showed that in MgFe2O4 coated with PEG-4000, there was a shifting in the wave number 2885.5 cm-1 to 2924.1 cm-1 in CH bond which was the bond of PEG- 4000 and a shifting in the wave number 316.3 cm-1 to 300.9 cm-1 on the metal oxide bond (MO) which is a uniform pattern of MgFe2O4. The presence of silica which has coated the magnetic material is shown in the 455.2 cm-1 number of Si-O-Si (bending) group.]]>

<![CDATA[Liquefied Natural Gas (LNG) is one of the potential alternative fuels to replace conventional fuels. Using LNG as fuel in Indonesia especially Yogyakarta will give many advantages, for instance, reduced greenhouse gas emissions so that eco-city in Yogyakarta can be realized. Although LNG has many advantages, LNG still contains many hazards whether during storage or distribution, the major hazard is radiant heat. This study aims to analyze and simulate hazard scenarios when transporting LNG such as fire pools, fireballs and vapor clouds and establishing exclusion zone by Areal Location of Hazardous Atmospheres (ALOHA) simulation. This study assumes that the diameter of the tank leak is 1 in and 3 in. The simulation results the exclusion zone from pool fire’s heat radiation from 1 in and 3 in leaks are more than 14 m and 39 m. While the safe distance of the fireball is 799 m. While in the distance vapor clouds that have a possibility of fire for the diameter leakage of 1 and 3 in are 21 m and 59 m.]]>

<![CDATA[Reaktor Serba Guna G.A Siwabessy (RSG-GAS) was built since 1983. RSG-GAS is a type of research reactor equipped with heat carrier and cooling system which serves to remove heat arising from fission reactions. In the heat carrier medium, the reactor equipped with a secondary cooling system using water originating from PAM Puspiptek. Water used in secondary cooling systems can cause some major problems of crust, corrosion, and moss or microorganisms. In this research, the phosphorus (orthophosphate), zinc, and conductivity and pH in the secondary cooling system have been measured to determine whether or not the flow rate of the injection system is used. Determination of concentration of the elements was performed using a DR / 2400 spectrophotometer portable device with ZincoVer 5 Powder Pillow reagent, cyclohexane for zinc concentration, and PhosVer 3 phophate for phosphorus concentration. From the results obtained, the overall flow rate of injector injection of 1.7 L / h gives a good result. Significant differences occurred only in conductivity values ​​dated July 21, 2009 both in piped water and cooling towers exceeding 950 μs / cm. And the value of orthophosphate concentration dated August 4, 2009 that exceeds 10 ppm.]]>

<![CDATA[Abstract—In Indonesia the numbers of orthopaedic surgeons are still not able to cover all demand. Badan Pusat Statistik (2015) reported that there are merely two orthopaedic surgeons in Lampung province having to serve about 8.117.268 people. Meanwhile, based on Ministry of Health of Republic of Indonesia, the ideal ratio between doctor and people is 12.2 doctor for each 100.000 people. Besides that, sometimes the surgeons need to serve more than one medical facility. Consequently, the patients might feel unpleasant. The lack of human resources becomes the main reason for developing expert system for diagnosing orthopaedic diseases. The expert system is able to diagnose orthopaedic diseases as well as fracture, dislocation, osteoarthritis and osteoporosis. The system is developed by using forward chaining methodology. This methodology is suitable for identifying a disease based on their symptoms. The result shows that the expert can answer 45 % of questions by identifying 6 main symptoms without continuing to following symptom questions.]]>
