Published: April 2021

Abstract
In this paper we represent an algorithm for finding the interval solution using gradient vector. This algorithm applies the optimization problem based on gradient vector in order to obtain the lower bound and upper bound of the interval solution. In this method, initial solution has been used with stopping criteria to compute the solution. An example problem is solved to represent this method with μ=0.5, μ=0.1, μ=0.05, and μ=0.01. By this method, we obtain optimal numerical solutions results with μ=0.01.

Published: April 2021

Abstract
Volcanic ash is dangerous for aviation because it can harm the plane engine. This study built a simulation of volcanic ash dispersion of Soputan in Indonesia, which erupted in December 2018 with the combination of the PUFF and Lagrangian methods. These combination methods gave a better result because it included the advection, diffusion, sedimentation vector, the geographic factor, wind area, eruption time and duration, and lifetime particle in the air. The simulation result was compared with the satellite image from Volcanic Ash Advisory and calculated the area ratio (AR) as well as the angular deviation (α).
Augmenting the spatial resolution of climate-change temperature projections for city planners and local decision makers
Authors: Jijón Juan Diego , Gaudry Karl-Heinz , Constante Jessica , Valencia César 
Published: April 2021

Abstract
Before the 2010, studies in climate change (CC) projections embracing scales below 3° were difficult to find. This has changed dramatically over the past ten years, with literature addressing high resolution grids for climate studies, allowing a better understanding and forecasting of CC at finer scales. However, downscaling methods remain poorly explored in urban planning. Research shows that the main difficulties relate to mismatches between data needs and data availability, terminology, constraints of information technology and maps that inform spatial planning decision-making processes. Based on dynamic downscaled maps for RCP 4.5 and RCP 8.5 at 10 km resolution published by Ecuador’s Ministry of Environment and Water (MAAE), we develop a method for augmenting the resolution scale at 30 m. We use digital elevation models and Landsat 4/5/7/8 satellite imagery for land surface temperature (LST) and present a series of steps and equations before applying Stefan Bolzman’s law. We present the necessary equations between the filling-in of LST outliers, and their projection onto air temperature at 2 m height, taking surface emissivity estimates based on (Alves et al 2017 J. Hyperspectral Remote Sens.
7 91–100). We extrapolate the resulting air temperature in time with Fourier’s series, and for the purpose of coherence among scales, we upscale air temperature maps at 30 m to those at 10 km resolution. The resulting CC projection maps are validated with the temporal series of air temperature (max, min, mean) from the meteorological station in the Ecuadorian city of Portoviejo (Student’s t-test) for the period between 1981 and 2005, with Portoviejo city facing temperature increases of up to 2 °C under RCP 4.5 scenario in the period 2011–2040 vs 1981–2005. The final CC maps have an augmented resolution of 30 m, are compatible with those of MAAE, and offer a low-cost procedure for informing land-use and urban planners, as well as local development decision makers, of temperature anomalies due to climate change.

Abstract
This research aims to assess community coping capacity especially in implementing post-tsunami disaster mitigation and adaptation in the coastal environment of Sumberagung Village. Sumberagung Village is a vulnerable area exposed to the tsunami. The past tsunami in 1994 has caused many losses to the people at Pancer Beach and Pulau Merah Beach. More than 200 people were dead at Pancer Beach. Data collection techniques on this research could be divided into two; primary data and secondary data. Primary data is obtained by conducting field surveys and in-depth interviews with the local inhabitants. While secondary data is obtained through relevant government agencies such as the Regional Disaster Management Agency (BPBD), Village Monograph Data, and Statistics Agency Bureau (BPS). Data identification was carried out in a qualitative descriptive manner by adjusting the findings of the field with the study of existing theories. The results of the study indicate that in general the appeal for the threat of a tsunami disaster has already existed but has not been comprehensive. On the other hand, not all of the inhabitants have not taken many lessons learned from the 1994 tsunami. Adaptation in the form of shelter that is safe from the threat of a tsunami has not been seen by residents in Pancer Beach. This field condition shows that after the 25 years of the tsunami event, the local residents have not been fully able to implement a mitigation strategy, especially on emergency.

Abstract
In 2019, Depok Municipality in Indonesia has participated for the second times in PROKLIM (Program Kampung Iklim-bahasa) which is focussed in RW 10 Baktijaya Village. In previous year, community activities in biopori holes, family herbal planting (TOGA) and rainwater infiltration well (RIW) was difficult to be updated. Therefore, in this study unmanned aerial vehicle (UAV) is applied to acquire location of PROKLIM in Baktijaya village with very high resolution image. Herein, DJI Phantom 4 Pro was flown at 100 m height to capture images of participated houses. The image from UAV then processed with Agisoft Photoscan to generate orthophoto image. With the guiandce from local community leader, biopori hole, TOGA and RIW locations were tagged using Avenza Maps and input into ArcGIS. Layers from UAV images and field survey then integrated to produce maps of biopori hole, TOGA and RIW activities. The map of PROKLIM activities was successfully generated from UAV image and Avenza Maps application. Resulted maps are very useful for updating submission to PROKLIM registration website in Indonesia’s Ministry of Environment and Forestry.
Updated Geologic Structures and Stratigraphy of the Darajat Geothermal Field in Indonesia
Authors: Intani Rindu Grahabhakti , Wicaksono Satrio , Golla Glenn , Suryantini  
Published: April 2021

Abstract
The main objectives of the evaluation of the geologic structures and stratigraphy of the Darajat geothermal field are to refine and update both the Darajat conceptual and geologic1 models. Re-interpretation of the borehole image logs, additional petrographic analysis of rock cuttings and cores, integration of subsurface data from the wells drilled during 2009-2011, and recent resource observations allowed definition of at least seven (7) lithologic units based on the dominant rock type. The updated stratigraphy of the reservoir was correlated with the surface rocks to develop a volcano-stratigraphy and geochronology of the Darajat geothermal system. The andesite-intrusive complex, which comprises the Darajat geothermal reservoir and the hypothesized sub-volcanic portion of an earlier liquid-dominated geothermal system, belongs to the Kendang Volcanics and makes up subsurface Units A and B. The interpretation of the major volcano-tectonic features and structures at Darajat was refined through the analysis of the Light Detection and Ranging (LIDAR) data/imagery that was acquired in 2014. The LIDAR Digital Elevation Model (DEM) hill-shade map shows several conspicuous volcanic vents in Puncak Cae, Gagak and Kiamis. The prominent Kendang Fault, which extends to the Kamojang Field in the northeast, might be a section of the ring structure of an earlier volcano, herein, called Kendang. Wellbore image data from several wells suggest that the Kendang Fault may dip at 70° eastward. Although needing further substantiation, we hypothesize that the decompression event that preceded the development of the steam-dominated geothermal reservoir at present might be related to the eruption of the Kendang volcano. The Gagak Fault is another prominent surface structure and believed to form during the eruption of the resurgent Gagak volcano after the eruption of the older Kendang volcano.

Authors: Rajyalakshmi M , Rao M Venkateswara 
Published: April 2021

Abstract
Pocket milling finds applications in ship building and aerospace industries. To cut the required profile of the pocket on the material various tool trajectories may be used. Surface roughness is one of the quality parameters to accept products at the same time production time must be reduced to reduce the production cost. This shows the need of selecting the best parameters machining parameters to get good surface finish with less production time. Tool trajectories also play a vital role in pocket generation and production time. In the current study, first, optimum machining parameters are identified for AISI304 using Taguchi L9 Orthogonal Array and Grey Relational Analysis. Experiments are done with Speed (S), Feed (F) and Stepover (SO) as the influencing parameters. Secondly, suitable tool path is to be identified to improve the surface quality (SR) and Material Removal Rate (MRR). Two tool paths viz, follow periphery and zigzag are used to generate pockets. For each tool trajectory, from the obtained results, Grey Relational Grade is calculated. The combination of parameters with highest Grey Relational Grade is identified as the optimal parameters. Confirmation experiments indicate that predicted responses are closer to the optimal values.

Published: April 2021

Abstract
3D printing or Rapid Prototyping (RP) or Additive Manufacturing (AM) is an innovative manufacturingmethod that is mostly used for prototypes in various Industries such as Aerospace, Defense, Medical, Automotive, etc. One of the worthy and widely used 3 D printing techniques is Fused Deposition Modeling (FDM), which involves adding melted material layer by layer. FDM has several benefits over other manufacturing methods. While setting the 3 D printing options, we have to take several parameters into account, such as speed, layer thickness and infill density, etc. The present experimental work illustrates the performance of ABS built parts fabricated by AION 500 make FDM machine. The quality of parts produced by FDM process mainly depends on the selection of process parameters. The present research work consists of process parameters such as layer thickness, infill density and speed of deposition, etc. This study aims to find effects of process parameters on different performance parameters i.e., mechanical considerations (impact strength), build time, surface roughness in a systematic manner with less number of experimental runs. Taguchi design of experiment (DOE) approach has been used to save cost and time of experimentation. Statistical significance of process parameters is analyzed using analysis of variance (ANOVA). The significant parameters for optimum results and optimal parameter setting has been suggested using S/N ratio.

Published: April 2021

Abstract
Basically, roller burnishing process is one of the surface finishing processes. In this process, a hard and highly polished roller will be pressed against a rotating specimen, this causes plastic flow on specimen surface from the peaks of surface irregularities into the valleys, which results in a reduction in the surface roughness considerably. This is a type of cold working whichalso results in improvementof micro-hardness, refinement of microstructure on the surface of the specimen under consideration. This work aims to understand the versatility of roller burnishing processand to understand the effect of the number of burnishing passes to enhance surface properties. Surfaceroughness, electrical conductivityand microhardness were studied in the present work. Experimental work was done on aluminium AA7075-T6 alloy. The parameters under which the burnishing was done were burnishing force, spindle feed and speed and are kept constant in the present work.

Case Studies on Condition Assessment and Repairs for Fire Damaged Reinforced Cement Concrete Structures
Authors: Yenigalla Raja Veerendra , Sajja Satish 
Published: April 2021

Abstract
In India, the shift in the mode of construction of structures from load bearing walled to framed, started in the early eighties. Concrete is highly durable and has very good compressive strength, but is expensive compared to the materials used for load bearing walled structures. Inspite of the cost, since the durability is more, most of the structures being constructed are RCC structures. However, concrete structures are damaged due to the action of fire. Though concrete has good resistance to fire, it is not completely fireproof. This study presents two case studies on structures damaged by fire. The condition assessment, Non Destructive Testing for quality evaluation of the concrete and the suggested repair techniques are discussed.

In this study, we are using of lime and geo synthetic material for stabilization of soil. Lime is an efficacious product to be mixed with fine grained soils with high plasticity and it improves certain properties of soil due to its chemical action. Stabilization of expansive soil with geo-textile will increase the stiffness and load bearing capacity of the soil through frictional interaction between the soil and geo-textile material. The lime is mixed in different percentages and reinforced with geo-textile by placing at certain depth with in sample height of four layers. In conclusion it shows an improvement of strength is in terms of CBR and peak load.
