Published: October 2019

Abstract
The development of the global and regional strategic environment has an impact on the development of the national strategic environment. The Territory of the Republic of Indonesia (NKRI) region which is a world crossing position is the world’s maritime axis where the flow of world transportation and world telecommunications is passed. The negative impact that is felt at this time is the tip of increasing the number of transnational organized crime (TNOC) that occurred in the NKRI. So it is necessary to do research on how the implementation of handling transnational crime at this time, especially in locations that are factual or potential occur such as in the waters of Nunukan-North Kalimantan Province, Indonesia which is directly adjacent to the City of Tawau-District Sabah, Malaysia. From the conditions of implementation of the handling it can be found the root of the problem so that a strategy can be formulated to improve the handling of transnational crime in the territorial waters of the Republic of Indonesia with other countries.

Published: October 2019

Abstract
The Indonesian maritime security agency called Bakamla is an institution that has the duty to carry out safeguards, oversight, prevention and prosecution of violations of law in the territorial waters and jurisdictions of Indonesia by synergizing and monitoring the implementation of patrols in the waters by relevant agencies. Bakamla is a manifestation of the realization of Indonesia’s concept as a maritime axis, as the newly established institution Bakamla must be able to regulate and manage institutions that have authority in the sea. The problem with Bakamla is that it does not have an integrated system that is able to manage resources in several institutions, especially institutions that have legal authority at sea. Enterprise Resource Planning (ERP) is a system that can overcome the problem of resource management in several institutions, ERP is a system that integrates several institutional tasks so that it can streamline institutional activities, facilitate interaction between institutional units and provide easy access to information. This study aims to develop an ERP application for the planning, assignment, supervision and control processes in each of Indonesia’s marine security areas. This ERP is developed with the Waterfall method which is a sequential process design which in the process looks like a waterfall flow from the concept design process, project identification, analysis, design, coding, testing, implementation and maintenance. The results of this study have been able to regulate all supervisory activities, control and assignment of resources of each institution under the coordination of Bakamla so as to improve marine security in Indonesia.

Abstract
The study on the effect of soaking salt and atung (Parinarium glaberimum, Hassk) has been conducted to investigate the production and quality of dried salted Bony flying fish (Cypselurus oxycephalus). There are two types of soaking salt used in this study i.e. gradual soaking (5 and 10% salt concentration) and single soaking (25% salt concentration). Three types of quality parameter used in this experiment i.e. organoleptic (appearance, smell, taste and texture), chemical (water content, salt content, protein content, peroxide number) and microbial (Total Plate Count). The yield of dried salted bony flying fish (C. oxycephalus) obtained through gradual soaking of salt and atung was 21.85 and 23.00% respectively which is less than the yield obtained through single soaking salt treatment (32.57%). For chemical parameters, the quality of dried salted of bony flying fish obtained through gradual soaking salt and atung were 16.12 – 16.96%, 76.37 – 79.15%, 4.82 – 8.67%, 0.23 – 0.34 mg.ek./g, and 4.03 – 4.56 (Log X)( 1.07×104 – 3.63× 104 colony) respectively which is better than that of single soaking which have chemical parameters of 22.66%, 53.26%, 18.68%, 0.43 mg ek./g and 5.26 (Log X) ( 1.82 x 105 colonies) respectively. For organoleptic analysis, the quality of dry salted flying fish attained from gradual soaking salt and atung were 7.4 – 8.0; 7.3 – 7.6; 6.9 – 7.4; 7.4 – 7.6 respectively whilst from single soaking salt were 7.2; 7.2; 7.2 and 6.5 respectively. Organoleptic results achieved from gradual soaking salt and atung seems to have slightly higher quality compare to single soaking salt.

Authors: Wattanasiriwech S , Wattanasiriwech D 
Published: October 2019

Abstract
Domestic ceramic industrial demand requires intensive searches for a new source of ball clay with acceptable quality. Analysis of clay samples derived from a new seam in Payao province, northern Thailand was performed using a series of techniques such as X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM), laser diffraction, thermogravimetric analysis (TGA) and L*a*b* color space method. Geological study of this clay seam showed the division into 5 sub-layers, from top to bottom, and was coded as KR, KC KA, KB and KQ respectively. The main minerals found in these clays were illite, quartz, kaolinite and rutile with a trace of clinochlore. KQ was quartzitic with a relatively low clay mineral content. KR was reddish due to the high content of iron bearing mineral. This clay was least refractory so it was not attractive for high firing white ware industry. In KB layer, large particles of plant relicts were generally observed so it showed abnormal distribution of the particle size and a substantial thermal weight loss. KA and KC showed the greatest potential for utilisation in whiteware industry. These clay samples were off-white after firing at 1150 °C.
Effects of pore water pressure on cohesive-frictional slope stability by limit analysis
Authors: Wulandari S N , Li A J , Wahyudi H 
Published: October 2019

Abstract
In the region there was generally influenced by seasonal weather such as highly rainfall intensity, the slope failure will be influenced by the existence of water and these conditions may trigger the changing of failure surface on the slope. The increasing pore water pressure causes shear strength reduction and shear stength enhancement. Consequently, the water level changes need to be evaluated conscientiously. In this paper, the various water levels are applied to perform the different pore water pressure conditions below the ground surface. Many methods are commonly used to predict the slope stability failure mechanism, including limit analysis. Limit analysis has been more widely employed for stability assessment in recent years because of its accuracy. In limit analyses, gravity multiplier will be adopted in this paper by using two-dimensional (2D) numerical approach to identify the failure mechanism. The results will be verified by comparing this study to previous studies.

Authors: Wang W , Yuan Q , Jiang H , Chen P S 
Published: October 2019

Abstract
Based on the project of Erzhuangke expansion tunnel, this paper aims to investigate the influence of the blasting vibration caused by the expanded tunnel excavation on the adjacent existing lining, then a reasonable safety control criterion is proposed. The 3D finite element analysis, combined with field test, was employed to analyze peak particle velocity (PPV) and the maximum tensile stress of the existing lining under the closely tunnel blasting. The results demonstrate that the blasting vibration attenuation rate of existing lining is faster within the range of about 1.5B from the blasting source, then gradually tends to be flat, and the two sides are basically symmetrical distribution. However, the PPV and tensile stress of the side wall and arch waist of the existing lining nearest to the blasting source are significantly larger than those of other locations, so it is more likely to be damaged. The numerical simulation results are in good agreement with the field test, which also verifies the accuracy of the field test results and the rationality of the numerical simulation. Moreover, the safety control criterion based on the PPV and maximum tensile stress is established to ensure the operation safety of existing tunnels, and the PPV safety criterion of existing lining is 10.73 cm/s, so that the maximum allowable charge of a single section should be controlled within 41.05 kg.

Published: October 2019

Abstract
Spent catalysts generate leachates that cause very serious environmental problems. This study shows the evaluation of the influence of applying a base to the leach recovered from an exhausted catalyst obtained from the “Esmeraldas State Refinery” in Ecuador. The main goal was to increase the percent concentration by mass of lanthanum and in turn reduce the concentration of aluminum through its precipitation. The agent used was 4.0 and 5.0 M sodium hydroxide and the pH was adjusted to stimulate the precipitation. Results show that the agent used is a precipitator of aluminum since the concentration of lanthanum increased up to 44%. The use of metal hydroxides in leachates is a valid alternative for the removal of heavy metals in order to prevent the contamination of the environment.
Joint prediction of CO, NOx, NMHC pollutant concentrations in urban area
Authors: Zhao JL , Sun MX , Li Q 
Published: October 2019

Abstract
Primary air pollutants could directly and indirectly (through generating secondary air pollutants) threaten natural or human systems. In particular, urban air pollution issue becomes more and more significant in the recent decades, as a result of rapid urbanization. However, the estimation of multiple-pollutant concentrations is limited by high spatial and temporal variations, which hinders the accuracy of mechanistic modeling of air pollution. In this study, we employed an Artificial Neural Network (ANN) model to jointly predict multiple primary pollutants, including CO, NOx, and nan-methane hydrocarbons (NMHC), over the urban area of Italy. The results showed that performances of the ANN model (MSE and Pearson correlation) in joint prediction cross multiple pollutants were much better than in prediction of any single pollutant individually, indicating the joint measurements of multiple pollutants could favor the machine-learning model by providing useful information from one pollutant to predict another.

Authors: Tunthawiroon P. , Chiba A. 
Published: October 2019

Abstract
This research aims to investigate the effects of Si concentrations on the microstructure and formation of the intermetallic phase of Co–Cr–Mo–xSi alloys. The Si concentration (x) was varied between 0.1, 0.5, 1.0, 3.0 and 5.0 wt%. The microstructure and intermetallic phase of the solution heat-treated Co–Cr–Mo alloys were characterized using SEM-EDX, XRD and TEM. The microstructure analysis revealed that Si concentration played a role in the evolution of intermetallic phase precipitating in Co–Cr–Mo alloys. Two types of intermetallic phased were found in the Si-doped Co–Cr–Mo alloys. The σ phase was identified in the alloys containing Si between 0.1-1.0 wt% while the increase in Si (3.0-5.0Si) contributed to the formation of the χ phase. The calculated lattice parameters of the intermetallic phase precipitated in the 3.0Si and 5.0Si alloys correlated well with those of Co5Cr3Si2 phase.

Published: October 2019

Abstract
It is noted that when extending the range of products made by plate rolling mills, it becomes relevant to improve the algorithms of the automatic parameters control systems. We hereby present a structure that explains the SMS Demag AG concept of automatic control over stand roll gauge and gaps. This concept is implemented in the automatic gauge control system (AGCS) of Mill 5000, Magnitogorsk Iron and Steel Works. We describe the drawbacks of the AGCS that manifest when rolling <10 mm plates. The most serious drawback is the tear of metal pieces from the trailing edge, which is caused by the inappropriate functioning of the gauge assignment and adjustment system. We present the structural diagram of the gauge calculation system. We also describe the functions of a system for dynamic compensation of disturbances. We provide rationale for excluding the roll counter-bending and deformation correction signals. The paper proposes a method to control hydraulic screwdowns, which is essentially about a quick increase in the inter-roll gap at the workpiece “trailing edge” during the last pass, which must be done when rolling thin plates. We analyze the oscillograms of signals describing the gauge interference when the proposed changes are implemented. We prove the technological efficiency of using the proposed control method on Mill 5000.

Published: October 2019

Abstract
This article discusses the prospects for the use of power units based on renewable energy sources for additional and emergency power supply of surface robotic systems. This kind of complex power unit can be built on the basis of renewable wind and solar energy and generate at least 10-15% of all the electrical energy required for a vessel. Considered one of the main problems of designing this type of complex power unit - the creation of a promising wind power systems (windmills). The windmill under development should meet a number of necessary criteria regarding reliability, power, noise level, and design constraints of the surface platform itself. The rationale for the design of the windmill is given. Further, the design of the windmill is optimized by the criteria of aerodynamic power, taking into account these limitations. The aerodynamic comparison shows the superiority of the proposed design of a windmill in relation to analogues on all the most important quality criteria. The features of the implementation of the electrical connection scheme of a windmill, solar panels and a diesel generator set into a single complex power unit are considered. For a robotized ship with a given power of the propulsion system, the complex power unit has been developed, which allows generating at least 10% of the power consumption.

Authors: Roy Choudhury M , Debnath K 
Published: October 2019

Abstract
In the present study, bamboo fiber reinforced polylactic acid (PLA) composites have been fabricated by hot compression molding using film stacking method. The compressive failure load behavior of single lap bolted joint of the developed composites has been experimentally investigated. The influence of the geometric parameters of mechanical bolted joint such as width to diameter ratio (w/d), edge to diameter ratio (e/d) and bolt fastening torque on the compressive failure load has been statistically analyzed. Taguchi’s analysis has been performed to find the optimum level of geometric parameters to obtain higher compressive failure load of the bolted joint. The w/d and bolt fastening torque were found to be significant parameters influencing the compressive failure load of the bolted joint. The compressive failure load of the bolted joint is more at a higher value of w/d and bolt fastening torque.

Published: October 2019

Abstract
Progress in Bio robotics is opening several doors to mimic the system and purpose of human limbs, thus allowing better prostheses for amputees. This paper presents EMG based Human Machine Interface framework for estimate of reference positions of prosthetic arm for patients suffering from above elbow amputation. In the present study, a set of information about the four basic motions regarding elbow flexion/extension along with the twist of radius and ulna referred as pronation/supination has been acquired from bicep of human arm. Upon muscle activation, the numerical data set points representing the electromyographic intentions were recorded using the Thalamic Labs product i.e. Myo Armband. To analyze these acquired signals, feature selection followed with feature extraction was done in order to classify the input data extracted from human muscle. Afterwards, the performance of Artificial Neural Network (ANN) for motion classification was evaluated. Utilizing the Computer Aided design skills in SolidWorks®, a 2-DOF prosthetic arm model was developed. A mathematical model of its kinematics based on Denavit-Hardenberg convention was presented in Matlab®. Forward kinematics model were analytically verified using Matlab® with that of PeterCorke® Robotic toolbox. In order to check the physical significance of proposed work, the information of forward kinematics from Matlab® linked with that of Solid works and was simulated with reference to the EMG intentions that were captured and classified to generate the reference positions of above mentioned four motions. The classification accuracy obtained from ANN i.e. 91.9% is found significant (p<0.01) for a group of ten healthy subjects.

Authors: Song Zhen-Qiang , Ohyama Kazuhiro , Zhu Shijie 
Published: October 2019

Abstract
In this work, the influences of pre-stretch ratio on the electrical actuation performance of dielectric elastomer actuator (VHB 4905) are systematically investigated based on theoretical calculation and experimental tests. As the pre-stretch ratio increases, the maximum actuation strain increases at the initial phase, while decreases as pre-stretch ratio further increases. The peak value of actuation strain is attained when the electromechanical instability is just refrained by the pre-stretch, which is experimentally measured to be 3.25, with the maximum actuation strain of 90%.
Effect of Morphology of Titanium Dioxide Nanoparticles on Photocatalytic Activity
Authors: Thiwakornkitkul Naphat , Suteewong Teeraporn 
Published: October 2019

Abstract
Dispersing nanoparticles into the matrix is a simple but effective method to improve properties of coating layer. Titanium dioxide (TiO2), known for its photocatalytic activity (PCA) to degrade organic substances and to protect microbial infection, is considered to be potential candidate. However, intense light is required to achieve high PCA. Scattering layer composing of hollow TiO2 nanoparticles, known as light harvester in solar cell devices, may be suitable for photocatalysis at lower light intensity. In this work, we studied the effect of hollow morphology to the PCA of TiO2 nanoparticles. Hollow TiO2 nanoparticles were successfully synthesized using hard-template-assisted sol-gel method. Transmission Electron Microscope (TEM) images show hollow TiO2 nanoparticles possessing 125-nm hollow core and 50-nm TiO2 shell. X-ray Diffraction (XRD) results revealed no crystalline peak for both calcined and non-calcined samples, but difference for each sample was reported by Ultraviolet-Visible Diffuse Reflectance Spectroscopy (UV-DRS). UV-DRS spectrum showed the higher diffuse reflectance for both hollow TiO2 samples than the dense counterpart, suggesting multiple light scattering and high reflection. However, energy bandgaps of amorphous and calcined hollow TiO2 samples are higher than dense counterparts.
