Published: April 2021

Abstract
Shallow earthquake produced by intra-island fault in a populated region could be a catastrophic disaster. Java island is the most populated area specifically in Western Java since there include Jakarta, the capital city of Indonesia. Cimandiri, Lembang and Baribis fault as main intra-island fault are considered to be responsible due to some shallow historical earthquake in Western Java. However, convergent plate margin such as Java Island generates a broad spectrum of deformation pattern that potentially distracts the deformation due to Baribis fault. In addition, slow relative motion of Sunda block and postseismic deformation due to the 2006 Java tsunami earthquake involve along those fault. Here, we intend to conduct a wavelength decomposition of strain rate calculated from GNSS (Global Navigation Satellite System) data. We expect to separate long wavelength due to wider-region deformation such as deformation due to the interacting plate and postseismic deformation to obtain Short wavelength due to each fault. We utilized the daily position of recent continuous geodetic data to produce strain rate. Therefore, we could apply a moving average filter to extract a short wavelength component. We obtained long wavelength (-150 to 150 nanostrain/yr) in Western Java shows extension indicating the postseismic effect is still continuous while short wavelength (-75 to 75 nanostrain/yr) varies in space.

Abstract
Ancient civilizations in Jombang left many historical relics in the form of temples, artifacts, and other archeological sites. Kedaton site is one of the newly discovered archeological sites. This site is buried under a few meters thick of Mount Kelud’s pyroclastic flow. Therefore, the distribution patterns of the site is needed to improve the excavation plan in order to maintain the structure of the site. One of the technical approaches that can be applied to map the site’s distribution in detail is geophysical survey. Geomagnetic method is a method commonly used in the case of archeological site investigations because of its non-destructive nature. The mapping process on Kedaton site is conducted by applying geomagnetic survey that utilizes physical parameters in the form of magnetic susceptibility. The reduce to pole filter is applied to magnetic data processing to aid interpretation, coupled with horizontal gradient method and analytic signal method further clarify the boundaries of magnetic anomaly sources. Reduce to pole filter indicates that the site’s brick detected as moderate to high magnetic anomaly values (more than 450 nT). This research succeeded in mapping clearly the boundaries of the site with an area of up to 6000 meters2 with the shape of the site resembling a building with several chambers. The main chamber is in the north which is the widest chamber, and small chambers are found on the south side.

Published: April 2021

Abstract
Pandeglang Regency is located in the southern coast of Java Island which is adjacent to the megathrust subduction zone. This zone originates from the meeting of the Indo-Australian Plate which is subducted under the Eurasian Plate. So that it can cause frequent earthquakes due to the movement of the plunging plates. Other than that, Pandeglang Regency is also bordered by the Sunda Strait in the western part where the region has Mount Krakatau which has the potential to cause earthquakes due to volcanic eruptions. Therefore, it is necessary to identify the level of earthquake hazard in Pandeglang Regency as a first step in disaster mitigation. Determination of earthquake hazard level in the study area is using the method of scoring the earthquake hazard level parameters based on “Peraturan Menteri Pekerjaan Umum No. 21/PRT/M/2007” and using spatial analysis. These parameters are the physical properties of rocks, slope, seismicity (magnitude, peak ground acceleration, and intensity), and the distance of the region to the fault zone. For the calculation of PGA (Peak Ground Acceleration) using the empirical equation from [10] and calculation of earthquake intensity using the empirical equation from [9]. The level of earthquake hazard is divided into three categories: low hazard level, medium hazard level, and high hazard level. The results of this study indicate that there is no low hazard category in Pandeglang Regency. For the category of medium hazard level has an area of 1719.404 km2 (62.959%). And for the high hazard level category has an area of 1011.573 km2 (37.041%). In almost all sub-districts there are medium and high hazard categories. Subdistricts that does not have medium level of hazard category are Patia and Sindangresmi Sub- district. And sub-districts that does not have high hazard level category are Cibaliung, Cimanuk, Karangtanjung, Koroncong, Mekarjaya, Menes, dan Pandeglang Sub-districts. The largest area in the medium hazard level category is in Cimanggu Sub-district, 344.394 km2. And in the category of high hazard level is also in Cimanggu Sub-district, 396.980 km2.

Authors: Bioresita F , Puissant A 
Published: April 2021

Abstract
Temporary Surface Water (TSW) is defined as waterbody experiencing frequent drying phases (small ponds, puddles, and wetlands) or correspond to surfaces frequently affected by flooding, thus causing hazards to human, settlements, and infrastructures. The Zorn is one of main river in Grand-Est, France which overwhelmed by strong precipitations from the Storm Eleanor (Cyclone Burglind). It caused inundation in Zorn surrounding areas. On 23 January 2018, data reported that floods occurred in Zorn watershed near to the municipalities of Brumath, Hoerdt and Hochfelden. Zorn River lies in the Moselle and Bas-Rhin departments with 580 km of linear streams. Historically, floods are frequently occurred in the Zorn watershed area. The municipalities of Eschbourg, Brumath and Dossenheim-sur-Zinsel are the most affected floods areas. Synthetic Aperture Radar (SAR) is an effective way to detect surface water over large areas. Sentinel-1 is a new available SAR, and its spatial resolution and short temporal baselines have the potential for surface water rapid mapping. Thus, the objective is to perform rapid mapping to produce flood map around the catchment of the Zorn River (next to Brumath).

Published: April 2021

Abstract
Coastal areas have a significant role in human life worldwide, where world economic activities are concentrated in coastal areas. One of which is the activity of loading and unloading import-export goods through ports. Ports management must use a nautical chart to ensure the safety of shipping activities. The nautical chart contains graphical information from the sea and coastal areas, namely: seabed topography, natural and artificial seabed features, coastlines, navigation hazards, both natural and artificial navigation aids, tides, currents, human-made structures such as ports, buildings, and bridges. Seabed sediment is also essential information that must be available in the Nautical Chart. Several techniques and methods are used to make a seabed sediment map, namely mechanical grab (lead line, grab sampler, coring) and acoustic (side-scan sonar, singlebeam, and multibeam echosounder). This paper reviews seabed sediment mapping techniques and proposes techniques and methods in the future.

Published: April 2021

Abstract
Natural fiber reinforced composite materials are most increasingly used as sustainable structures in engineering industries due to their vast availability and eco-friendly nature. In this regard, an emphasis is given in the present work to the use of natural fiber in structural composite material in place of synthetic fibers for structural applications. In the present study, the mechanical properties and free vibration characteristics of a pure green composite laminate were experimentally evaluated. For complete understanding of the behaviour of green composite material, a second laminate is prepared using synthetic resin. Two types of composite laminates were fabricated by hand layup method. In the pure green laminate, natural flax fiber is embedded in cashew nut shell liquid (CNSL) resin and for the second laminate epoxy resin is used as matrix. The flax fiber is preferred due to its high mechanical strength among all the natural fibers. Alkaline treatment is done for the natural flax fiber before fabrication to remove impurities and also improve the surface adhesion. Both the laminates were tested for mechanical properties and free vibration characteristics according to ASTM standards. The experimentally evaluated tensile, flexural properties and modal frequency values of two types of laminates are reported and discussed.

Published: April 2021

Abstract
CO2 capture and storage (CCS) is a promising technology to mitigate CO2 emission from fossil-fuelled power plants. The three existing CO2 capturing technologies popularly used in the fossil-fuelled thermal plants are pre-combustion, oxy-fuel combustion, and post-combustion. Absorption, adsorption, membranes, chemical looping, and cryogenic are the prominent methods used in post-combustion technique. The cost reduction and energy savings are the two important challenges in CCS. Secondary power generation by using an organic Rankine cycle (ORC) from waste heat available from flue gas and CO2 capturing units is an attractive option. A comprehensive review of research works carried out pertaining to the integration of ORC in power plants in the recent past is presented in this paper.

Published: April 2021

Abstract
With the increasing global demand for fuels, there is a need to reduce vehicular emissions which are one of the major causes of air pollution around the globe. NOx emissions leads to health issues, acid rain, global warming, etc. Diesel engines are the major sources for NOx emissions. Hence there is a need to reduce the emissions from the engines by means of alternate fuels and emission control technologies. This investigation deals with the effect of exhaust gas recirculation (EGR) on single cylinder, direct injection diesel engine using plastic oil and diesel blend (10% plastic oil + 90% diesel) at EGR rates of 5%, 10% and 15%. Plastic oil blends were able to operate in diesel engines without any modifications and based on the results, EGR decreases the NOx emissions with a minimum increase in specific fuel consumption. The engine with the EGR rate of 15% and at the full load condition, the emission level of NOx has been decreased from 1327 to 661 ppm. Hence it was concluded that the low emission level of NOx can be obtained using EGR for the plastic oil blend. The results showed that DPB+EGR15 blend had the least NOx emission.

Authors: Johnson Joji , Manikandan S 
Published: April 2021

Abstract
Many models are available to simulate the solar radiation incident on monofacial photovoltaic panels but these models cannot be used to evaluate the radiation incident on a bifacial photovoltaic panel as it does not consider the bifacial gain due to ground reflection and diffuse sky radiation. In this paper an optical model was developed to measure the global solar irradiance on front and rear side of a bifacial photovoltaic module. The bifacial gain at the rear surface is modelled by considering the diffuse sky radiation and reflected component of light from ground and nearby surfaces. An optimised model is developed for Equatorial zone for maximum bifacial gain considering tilt and shading parameters. A comparative study on annual gain for the bifacial module compared to monofacial module also done for the topical latitude zone.

Published: April 2021

Abstract
The Personal Health Record (PHR) is a framework of health information exchange. In the digital age, hospitals and medical institutions are moving to an online platform to store the medical record of patients because physical storage has become quite labor-intensive, expensive and also very inconvenient in terms of maintenance and retrieval while online storage overcomes those obstacles. But there are still numerous privacy concerns as confidential health information may be accessed by unauthorized people. Storage of medical records and other patients related information on third party servers may be vulnerable to breaches as third-party servers usually do not possess a lot of security. To assure the patient’s authority over to their PHRs, this method is used, to encrypt the PHRs before storing on a server and that data is linked with the blockchain. In this paper, we propose a model and mechanism for control of data access to Personal Health Records stored on the cloud. To achieve efficient data access control for Personal Health Records, we use AES and SHA algorithm as an approach to encrypt each PHR file. The analysis and results exhibit the security and efficiency of our proposed scheme.

Published: April 2021

Abstract
Buildings are considered as a major consumer of electricity. It is said because 40% of the total energy produced is utilized by the buildings. Harnessing the solar energy by means of photovoltaics is seen as sensible option to meet out the buildings demand entirely or partially. Recent trends has seen BIPV systems as a viable option that not only enhances the aesthetics of the building but at the same time meets out the buildings energy demand. Apart from the aesthetics and electricity production, BIPV, which acts as an integral component of the buildings, reduces solar heat gain at the same time allowing daylight to enter into the building. This paper discusses the different cell technologies used in solar BIPV systems, different types of PV modules used for building integration, orientation and tilt angle optimization of panels, performance analysis with different case studies, cooling methods adopted in this technology and the main barriers that slows down the development of this system. Payback periods is also studied and discussed in this paper.
