Authors: Madinah R , Rusydi F , Boli L S P , Khoirunisa V , Fahmi M Z , Zaidan A H
Published: July 2020

We report a density-functional coupled with vibrational calculation on justifying the isomerization pathway of cyclopropene to propyne. The idea is to present the pathway in energy level diagram which the transition state is ensured by tracking a particular mode that supports the cyclic bond breaking and triple bond formation to occur. This mode decreases along the pathway and disappears at the transition state. To verify the designed pathway, the activation energy of the isomerization is used to find the rate constant with respect to experimental data at 500 K and 700 K by using transition state theory (TST). At those temperatures, TST predicts the rate constant at the same order of magnitude with the experimental result. It shows that the trend between calculation and experimental data is qualitatively in a good agreement, which implies that the designed pathway is justified. Furthermore, this study can be used as a guide if one needs to construct an isomerization pathway.

Authors: Novyanto O , Alfiyati N
Published: July 2020

High accuracy check master is a type of geometry gauge that often used to check the accuracy of Coordinate Measuring Machine (CMM) in the high-class metrological institutes and manufacturing industries. This type of geometry gauge is composed of several high-accuracy short gauge blocks and a large rod as its foundation. Conventionally, the measurement of high accuracy check master can be carried on by using measuring machine. Since the bench has limit up to 400 mm, the measurement of high accuracy check master more than 400 mm range is performed in two-step. Firstly, from nominal range of 10 mm to 400 mm and the other range by utilizing extension. In some cases, this measurement method has bigger expanded uncertainty value, i.e. more than 2 µm. Since the check master has important role to verify the accuracy of CMM, the quality of calibration system of high accuracy check master is required to be improved. This paper describes only to achieve high accuracy of measurement up to 400 mm. In the developed measuring system, the heterodyne laser interferometer is used as the reference. The optical configuration of laser is combined with the measuring machine as a moving part. In order to improve the accuracy of measurement, the refractive index of air and the temperature compensation are recalculated manually by Edlen’s formula and linear expansion equation, respectively. Using this method, the expanded uncertainty from calibration 400 mm high accuracy check master is less than 1 µm. The results had a good agreement to the measurement results from manufacturer with international certification, experimentally. In conclusion, this method can be applied to calibrate the high accuracy check master of 400 mm range.

Published: July 2020

Nanotechnology and Graphene Research Centre (PRINT-G) of Universitas Padjadjaran is currently developing fine bubble generator (FBG) technology which is applied for the fisheries sector to process aquaculture wastewater into clean water and as an aerator. In its implementation, adequate energy is needed, but it can be applied with cheaper electricity costs, such as renewable energy sources. In this research, a gravitational water vortex pico hydro power (GWVPHP) plant modeling has been carried out. .This system can be used under 2 meters head condition and for small water flow, that is suitable to use in fishing pond locations that do not have high head and limited water. It is known that the velocity of water flow is 0.4 m/s, and the head is 1.6 meters with the height level of the water varying every 5 centimeters increase in the range of 5 to 50 centimeters. As a result, we obtained the minimum potential power of 111.9 Watt and a maximum of 1,558.2 Watt. In modeling, we assumed that we used turbine with 80 percent efficiency, thus we obtained the turbine generation power of 89.6 Watt, and a maximum of 1,246.6 Watt. In addition, the modeling also uses 3 phase AC generators with an efficiency value of 70 percent, so that a minimum generator generation power of 62.7 Watt is obtained, and a maximum of 872.6 Watt is obtained. Control panel also used with an efficiency of 70 percent, so that a minimum power that produced is 43.9 Watt, and a maximum of 610.8 Watt. Fine bubble generator (FBG) that used for aquaculture needs 125 Watt to be functioned. Thus, the power that had generated by the gravitational water vortex pico hydro power (GWVPHP) plant could be supplied the energy needs of fine bubble generator (FBG).

Published: July 2020

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.

Published: July 2020

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.

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.

Published: July 2020

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

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.

Published: July 2020

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.

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.
