A.I.VE.LA. – the Italian Association of Laser Velocimetry and non-invasive diagnostics is a non-profit cultural association whose objective is to promote and support research in the field of non-contact or minimally invasive measurement techniques, particularly of electromagnetic-based and optical techniques. Through its Annual Meeting, AIVELA aims at creating an active and stimulating forum where current research results and technical advances can be exchanged and the development of new systems for laboratory use, field testing and industrial application can be promoted. The techniques addressed include Laser Doppler Anemometry – LDA, Phase Doppler Anemometry – PDA, Image Velocimetry – PIV, Flow visualization techniques, Spectroscopic measurement techniques (LIF, Raman, etc.), Laser Doppler Vibrometry – LDV, Speckle Pattern Interferometry – ESPI, Holographic techniques, Shearography, Digital Image Correlation – DIC, Moiré techniques, Structured light techniques, Infrared imaging, Photoelasticity, Image based measurement techniques, Ultrasonic sensing, Acoustic and Aeroacoustic measurements, etc. The first Annual Meeting was held back in October 1992 and, since then, the event has met large consensus among the research and scientific communities worldwide for the high scientific interest of the papers presented. The XXVII AIVELA Annual National Meeting was organised in collaboration with Istituto Motori – CNR and was held at the premises of Istituto Motori – CNR, in Naples, on 30-31 October 2019. This volume contains a selection of the papers presented at the event. The full Programme of the Meeting can be found at: http://www.aivela.org/XXVII_Meeting/final-programme.html. Trusting our Association and its initiatives will meet your interest, I wish to thank you in advance for your kind attention and hope to meet you soon at one of our events.

We are delighted to introduce the proceedings of the first edition of International Conference on Industrial Revolution 4.0 and Its Application in Science, Technology, Engineering, Education, and Mathematics (ICSTEEM 2019). The several of this paper from the joint conferencence of ICSTEEM 2019 and The 3rd Global Research on Sustainable Transport and Logistics. The technical program has brought researchers and practitioners around the world to a good forum for discussing, leveraging and developing all scientific and technological aspects that are relevant to digital society. We hope that the future ICSTEEM 2019 will be as successful and stimulating, as indicated with the contributions presented in this volume. Thank you very much for attention. Regard, Dr. M. Ikhsan Setiawan Dr. Janner Simarmata

Economic growth in Indonesia gives effect to the development of the logistics industry in Indonesia. Logistics Business is a sector that has a fairly high growth rate, where increasingly improved growth requires effective and efficient logistical support. In 2018, the Government of West Java implement the Innovation Inland Waterways which aims to create a channel width of the sea into the mainland so that containers can be transported by water rather than through the toll-road to Tanjung Priok, and make Inland Waterways as an Alternative Transportation logistics, Central Government, also has made Inland Waterways Cikarang Bekasi Laut (CBL) as the National Strategic Projects, which is expected to reduce the current density on the land logistics from Cikarang Industrial Area to the Port of Tanjung Priok and aim to optimize the potential of the river as an alternative canal path of transport logistics. Where the volume of land transport logistics in Indonesia has reached nearly 90%, and with the construction of CBL Inland Waterways is expected to reduce costs with the integration of multimodal transport logistics. The purpose of this study was to find a potential that can be developed as Alternative Transportation Logistics and determines the priority level of that potential. Retrieval of data taken through a questionnaire distributed to experts in the field of logistics and related to the research being carried out. The result indicated that the Economic aspect was the top priority among the other potential to developed.

End of Line tests have a crucial role in industrial processes to validate the products' quality. In automotive industry, engines at the end of assembling process are fully tested within hot test cells at different working conditions by mean specific test cycles. Vibration monitoring is widely used in order to identify potential faults in the assembly process. This contact technique leads to several disadvantages, mainly due to the accessibility and the characteristics of surfaces for accelerometers mounting (e.g. rotating parts, geometries complexes, high temperatures) and to the time-consuming setup procedures. These limitations can be overcome by using microphone sensors. This paper describes the development phases of an acoustic based fault diagnosis system, its integration on hot test cells and the results obtained over large number of engines tested. By mean some specific technical solutions the acoustics approach in the EOL fault diagnosis of combustion engines has showed itself to be compatible with the characteristics of the production industry environment, providing reliable and repeatable results. The latter has been demonstrated also by comparison with the traditional accelerometer technique.

Domestic Vertical Axis Wind Turbines (VAWT) are able to operate also when the wind speed is low and can be installed in the open spaces of housing areas. The Darrieus turbine is the most promising since it is characterized by higher efficiency, even if for applications at higher wind speeds with respect to Savonius VAWTs. Several researchers try to optimize the aerodynamics of the Darrieus rotors, allowing wind turbines to start rotation even in the presence of low wind speeds. In this paper the authors propose a numerical investigation of the flow field around a 1:4 scaled model of a pair of blades installed on an innovative Darrieus-type VAWT. A Reynolds Averaged Navier-Stokes-based CFD model was validated on the basis of the wind tunnel data, and the scaled turbine performance was analysed by numerically evaluating the effect of different geometric configurations and rotation angles on the turbine torque coefficients. The results of the simulations confirmed the capabilities of the proposed configuration to give valuable performance even for low wind speeds.

Aircraft analysis is one of the strategy that are applied in the airline industry to be able to compete with other airlines by determining which aircraft is more effective, efficient, and economic. In fact, some airlines cannot apply this strategy. With this analysis, the airline is able to compete. By Seat Load Factor (70%) calculation, estimated weight of seat vacancy can substitute to Cargo Allowable. The result of calculation and comparison will produce the effectiveness aircraft on payload optimization. The result of comparison analysis is able to be concluded that A 330-300 aircraft is the aircraft that can better implement Payload Optimization. The lowest Total Operating Cost in the amount of US 14,042.94.- Dollar compared to the B 777-300ER aircraft that have Total Operating Cost in the amount of US 21,887.06.- Dollar. With a larger Total Operating Cost is owned by B 777-300ER, A 330-300 has a greater profit of US 13,742.62.- Dollar compared to B 777-300ER which has profit of US 13,433.94.- Dollar.

When the formula for calculating the RPMT tariff does not have a standard calculation technique, the implementation of the calculation of the RPMT tariff between one area and another is different. Therefore, it is necessary to do a theoretical and empirical study to find the ideal RPMT calculation formula according to the Constitutional Court Decision Number 46 / PUU-XII / 2014. The results of the study show that the ideal pattern of RPMT calculation is that calculations based on Article 151 of the PDRD Law as it is reinforced by the Court of Constitution through Decision Number 46 / PUU-XII / 2014 which have canceled the Explanation of Article 124 of Law No. 28 of 2009 on the grounds that the imposition of a levy tariff that provides a maximum limit of NJOP without accompanied by a clear calculation system does not provide legal certainty that will cause injustice in its application. So the Central Government must immediately compile and discuss the Draft of Ministerial Regulation on Implementation and Retribution.
