Authors: Mar’ie K , Lestariningsih I , Nurlely  , Soejoko D S 
Published: July 2020

Abstract
Computed Tomography (CT) Scanner is a three-dimensional body imaging modality. For observation of moving organs, in addition to using Single-source CT (SSCT), Dual-source CT (DSCT) has been developed which is equipped with primary and secondary x-ray sources. The position of the two DSCT sources forms an angle of 90°, and at the time of image acquisition both rotate 90°. Thus the process of image acquisition of a moving body can be carried out in a relatively short time. If the same examination using SSCT, it is necessary to decrease the movement of organs which generally use beta blockers. In this research, in-house phantom has been designed to analyze the image quality character of the two types of CT which will then be compared. Phantom is cylindrical in shape and has a diameter of 20 cm and a length of 12 cm, divided into three sections of 4 cm each. The first module, phantom is intended for noise measurement, in the phantom implanted 16 cylindrical objects with diameters of 10 mm and 15 mm, made of 4 types of material with different Hounsfield Unit (HU) values, namely teflon (941.31 ± 14.61) HU, water (0.548 ± 0.43) HU, polystyrene (-26.38 ± 13.55) HU, and air (984.32 ± 27.97) HU. The second module, phantom will be used to assess the detectability. This section is filled with 26 cylindrical pipes with diameters, 2, 3, 4, 5, 6 mm for each of the 5 pipes and one other pipe with a diameter of 10 mm. All of these pipes will be filled with contrast media Iodine with varying concentrations. The third module, phantom will be used to measure spatial resolution and homogeneity. In this section copper ball objects will be implanted with a diameter of 0.19 mm and a length of 4 cm. Furthermore phantom will be used for measurement of noise, spatial resolution and detectability of this CT image from dual-source and single-source CT scans with the exposure conditions adjusted for clinical use.

Published: July 2020

Abstract
Dental hypnosis has been reported in many journals as a science since James Braid used hypnosis term in his publication in 18th century. Recent research supports the view that hypnotic communication and suggestions effectively changes aspects of the person’s physiological and neurological functions and can enhance the efficacy of various treatment interventions in dentistry. So, the dental hypnosis is truly science not a black magic. The acoustic parameter expression is a tool consisted of three parameters that are duration, pitch and intensity that is used to measure how effective the special sentences/phrases can bring the people consciousness state to unconsciousness state by giving some suggestion. It works by modifying people mind to change their fear of dental treatment for example, to be a contrary condition.

Abstract
This study aims to obtain information about the characteristics of rainfall in South Sumatra and its surroundings (Longitudes 99° – 107° East and Latitudes 1° - 5° South), which includes climatological anomalies and shifts in the time of diurnal rainfall peak events. This research data comes from TRMM PR 3B42 v7 with grid spatial resolution of 0.25 ° x 0.25 ° and temporal resolution of 3 hours, which includes two categories, namely climatology data for ten years (2008 – 2017) and 12 months actual data (October 2018 – September 2019), with main attention in December 2018 to February 2019. Climatologically the pattern of rainfall is similar to “Type A” of the Aldrian’s rainfall pattern. Meanwhile, the calculations of anomalies indicated a significant rainfall deficiency, starting in July to September 2019, which can be understood as the impact of the positive Indian Ocean Dipole. On the other hand it was found that the peak of rainfall on the west coast of Sumatra generally occurred at 16:00 to 19:00 (local time), which then shifted increasingly late towards both East (mainland Sumatra) and West (Indian Ocean) as stated by Vincent and Lane. Finally, about 30% of the study area did not experience a shift in peak rainfall time (RP time shift) and 40% of the other area experienced it of ± 3 hours and the rest experienced it with a longer time.

Abstract
Tomography technique is one method in geosciences adapted from medical field like CT Scan and MRI. In medical field, tomography is used to describe human’s body condition but in geoscience it is used to describe subsurface of the earth, like passive seismic tomography. Subsurface description like velocity data that expressed in tomogram is a result of inversion from travel time and ray tracing data. Tomography is done in various grid model (regular and irregular grid). Irregular grid give a better tomogram result, it is caused by it does not need big data of hypocenter or station. The distribution of grid also showed the good propagation model of ray tracing that influenced the tomogram result.

Abstract
A study of ultra-low-frequency (ULF) geomagnetic signals has been carried out prior to the onset of Nias earthquake M5.3 that occurred at 07:13:49 LT (Local Time) on September 6, 2018, in West Nias regency, North Sumatra, Indonesia. We analyzed three components of geomagnetic data H, D, and Z measured in Gunung Sitoli (GSI) geomagnetic station which is about 108 km from the epicenter, from January 2018 until December 2018. We used the polarization ratio method in terms of power spectrum density within 0.027-0.033 Hz frequency range to evaluate the geomagnetic data by applying Fast Fourier Transform (FFT). This work presents evidence of ULF geomagnetic anomalies exceeding the statistical threshold associated with Nias earthquake M5.3 which appeared starting from 3.5 months until 3 weeks before the earthquake. When these anomalies occurred, the value of disturbance storm time (Dst) index shows that there is no high global geomagnetic activity. Thus, it is concluded that the clear precursory anomalies detected are related to the earthquake.

Published: July 2020

Abstract
Hydrological and climatological parameters in several locations on peatlands in South Sumatra have been measured directly by a system called Sensory data transmission Service Assisted by Midori Engineering laboratory (SESAME). The parameters are rainfall, temperature, soil moisture, and groundwater level. This research has studied the groundwater level fluctuations and looks for the correlation between groundwater level and soil moisture in four locations, namely Saleh River 1 (SR1), Saleh River 2 (SR2), Lumpur River 1 (LR1), and Lumpur River 2 (LR2). The results are expected to be useful for fire disaster mitigation on peatlands, especially in South Sumatra. Based on time series data of groundwater level, the results show that there has been a sharp decrease in groundwater level at locations SR1, SR2, and LR1. The statistic calculation results show that groundwater level has a significant correlation with soil moisture in four study sites. The correlation coefficients obtained for SR1, SR2, LR1, and LR2 are r = 0.88, 0.97, 0.87 and 0.92, respectively.

Abstract
The variation of thermodynamic layers over the south coastal Java are important components associated with high potential fishery in this region. In addition, this area influenced by several ocean-atmosphere coupled interactions, such as Ocean Current System and Indonesian Through Flow (ITF) and Monsoon. This study designed to analyze spatial and temporal variations of Mixed Layer Depth (MLD), Isothermal Layer Depth (ILD) and Barrier Layer Thickness (BLT). The data used are salinity, temperature, nitrate and oxygen from CSIRO Atlas of Regional Seas (CARS), surface wind and evaporation from European Centre for Medium-Range Weather Forecasts (ECMWF), and precipitation from Tropical Rainfall Measurement Mission (TRMM). Based on the results, during JJA season (boreal summer) the ILD, MLD and BLT layers over the southern coast of Java are relatively shallower. The thickness of ILD was range from 10 – 30 m, while the thickness of MLD and BLT are about <10 m. Meanwhile, during DJF (boreal winter) and MAM seasons (boreal spring), the thickness of the ILD, MLD and BLT layers are deeper. The nutrient distributions are consistent with thermodynamic layer patterns. The highest concentration of nitrate, phosphate and oxygen tends to occur in the boreal summer season due to the upwelling phenomenon which causes the removal of nutrients in the inner layer toward the surface, whereas the lowest concentration tends to occur in the boreal winter season caused by the downwelling phenomenon.
Crustal structure beneath Simeulue Island, Indonesia: Preliminary study from a joint inversion of receiver function and surface wave dispersion

Published: July 2020

Abstract
Simeulue Island is located on the subduction zone between Indo-Australian and Eurasian plates. The Island is in the forearc basin west of Sumatra Island. Due to subduction process of Indo-Australian plate beneath Eurasian plate, high seismic activities occur around Simeulue Island. Two devastating megathrust earthquakes of 2004 Mw 9.2 Sumatra-Andaman and 2005 Mw 8.7 Nias earthquakes occurred close to the Island. Information of crustal structure may provide better understanding about tectonic characteristics. In this preliminary study, we investigated crustal structure beneath Simeulue Island from three temporary broadband seismometers. Crustal structure was derived from joint inversion of receiver function and surface wave dispersion. S-wave velocity profiles obtained from joint inversion may suggest that the crustal thickness beneath Simeulue Island is at about 20-25 km. S-wave velocity decrease is observed at depth of about 50-60 km depth. This low velocity decrease may be related to the subducting slab of Indo-Australian plate.

Abstract
In this study, the prediction of acid mine drainage was done by measuring dielectric contrast of sulphide mineral and its environment. It causes amplitude contrast of radar wave reflected by rock layer. This measurement was performed using electromagnetic method by use of Geo-Penetrating Radar or Georadar (GPR). The frequency of measurement was 250 MHz with perpendicular broadside antenna. It took place at pre-mining area whereas the surface soil was dry. GPR data was processed for enhancing data and amplification. The result of this research showed that the overburden and interburden layers were dominated by claystone or siltstone with little sandstone. The multiple that appear in the processed data looks relatively regular and evenly distributed in the layer, not spots which are characteristic of sulfide minerals.

Published: July 2020

Abstract
At present, there are many studies on "computer immunology" in the world, and there are many applications of immune genetic algorithm in engineering.The article discusses the immune genetic algorithm in the design of PID intelligent controller.Most objects in the practical industrial process fall in the distributed parameter system (DPS), where the proportional-integral-derivative (PID) control method is used to control the field. In this paper, the PID controller optimization method based on the immune genetic algorithm (IGA) (referred to as the PODM method) is applied to a class of distributed parameter objects to design the optimal controller, which is compared with several controllers based on the conventional tuning formulas. The simulation results suggest that the PID controller designed based on the PODM method can obtain relatively superior control effects in overshoot, tuning time, time integrated time absolute error (ITAE), and other indexes with relatively less control energy. The application of the PODM method to DPS can improve the control level of the PID controller in the industry at present.

RETRACTED: Research on the Fusion of Decoration Design and Modern Elements of the Oroqen Nationality Based on Big Data Analysis
Authors: Xue Wenfeng , Aruhan  
Published: July 2020

Abstract
The Oroqen nationality is one of the minority ethnic groups in the north of China. Oroqen is one of the oldest and rarest ethnic groups in China. Since the oroqen ethnic group still retains the characteristics of nomads, many related cultures cannot be retained as the farming culture, and the sharp decrease of population has also become a major problem. Protecting national culture has become an important means to highlight national characteristics and display national personality. However, in-depth study of the shapes and implications of national decorative patterns can better understand the history, humanity, production and life of the nation. In this way, the civilization of the nation can be inherited better, so as to provide a favorable theoretical basis for development.
