Abstract
Bio-based products represent a key component of global bio-economic growth. In the process of forming a bamboo fibre-based bio board in this study begins with the preparation of bamboo fibres to make it compatible as a filling material in polyester polymers. The mixing of bamboo fibre is done by considering the composition of the fibre material with the polymer used, namely polyester at a ratio of 90%:10%, 80%:20% and 70%:30% of the total weight of the mixture. This mixture is added with a natural substance that has been investigated to have resistance to microbial contamination (anti-microbial), chitosan at a ratio of 1%, 3% and 5% by weight of the total mixture of all components. Bio board printing is carried out using a hot press (moulding) tool. The functionality of bio-based and conventional natural fibre-based materials was investigated for a series of bio boards. The tests include tensile, antimicrobial activity and morphological testing using Scanning Electron Microscopy (SEM). The overall test results put bio board with a ratio of 70%:30% with the addition of chitosan as much as 5% wt as the best sample with a tensile strength value of 147 Mpa, the flexural value of 0.09 kN. The sample shows a good interface appearance of the bond that occurs between the polymer and the filler under the electron microscope.

Abstract
Lombok and Nusa Tenggara are one of the regions in Indonesia that have quite complex tectonic arrangements. With this order, not infrequently in the region there are often natural disaster phenomena. One of the most striking things is the occurrence of a series of earthquakes of magnitude Mw > 5.0 that rocked the northern region of the Island of Lombok on 29 July 2018 (Mw = 6.4), 5 August 2018 (Mw = 6.9), 9 August 2018 (Mw = 5.9), 19 August 2018 (Mw = 6.3 and 6.9) and 25 August 2018 (Mw = 5.5). This study aims to identify the condition of tectonic structures under the surface of the earthquake occurring region using the tomography method. This method utilizes earthquake travel time data recorded at 15 BMKG seismic stations. The tomogram results show the contrast of anomalous values in the Vp and Vs models. The contrast of the anomalous is associated with the presence of fault structures that have an allowance angle of about ± 20-30° and a thrust fault type, verified by focal mechanism ball data. This thrust fault is then indicated as the cause of the occurrence of earthquakes with magnitude Mw > 5.0, which shook the northern part of the island of Lombok in July-August 2018. According to the tomography result, the fault is located closer to the north side of Lombok Island than Flores Back arc Thrust.

Abstract
Understanding the main geothermal components such as clay cap, reservoir, heat source and faults structure can reduce the risk at the drilling stage. The role of the faults is very important since it can be a recharge/discharge medium of geothermal fluid. One method that can be used to identify the faults is the gravity method. The combination of the upward continuation and second vertical derivative (ML-SVD) methods is carried out to characterize the geological structure both the slope direction, depth estimation, dip estimation and type of structure. Upward continuation is carried out from a height of 0 - 2000 meters with an interval of 250 meters. SVD filter is applied at each height level. ML-SVD result shows that the fault structures at the study area have a value of dip > 70° with various fault configurations. Some faults are estimated at a certain depth under a layer of rock. ML-SVD shows a circular pattern that indicated as a caldera structure. The fault orientation of the study area tends SW-NE and NW-SE with dip perpendicular to the strike.

The simulation of evacuation from multistorey building using NetLogo
Authors: Lestari D P , Sabri A , Handhika T , Murni  , Sari I , Fahrurozi A 
Published: July 2020

Abstract
The occupants of a multistorey building are very vulnerable when disaster happens (e.g. fire, earthquake, etc.). In the worst case, the only way to escape is through the emergency stairways, in which they scramble with the occupants coming from the higher floors. This situation often creates bottlenecks along the way, which in turn extends the evacuation time. In addition, the panic situation increases the risks of accidents, causing injuries or even death. In this research, we use NetLogo to simulate the evacuation process from a simplified multistorey building based on some parameters, which are the placement of the emergency stairways, the number of occupants in each floor, the number of stories, and the height of the floor. We set simulation scenarios to analyze the relation between the number of stories with evacuation time in each configuration. In our experiment context, we conclude that when the time-limit applies, the total evacuation through stairways is not effective for buildings having more than three storeys.
Reservoir Characterization with Acoustic Impedance Inversion and Multi attribute Method on “Essen” Field, Talang Akar Formation, Sub-Ciputat Basin, North West Java
Authors: Nugroho E S , Riyanto A , Suardana M 
Published: July 2020

Abstract
Acoustic impedance and multi-attribute seismic inversion seismic are a number of seismic methods that can be used to map sandstone reservoir distribution. Using this method, we can separate the sandstone and shale in the Talang Akar Formation found on the “Essen” Field, Ciputat Sub-Basin. Both of these methods will be compared with each other in order to get more valid results in sandstone reservoir mapping. The inversion method used in this study is a model-based method. While the multi-attribute method used is the neural network in mapping gamma-ray volume, shale volume, and porosity. The inversion results are not able to image the sandstone distribution good enough because the range is too large and there is overlapping on the acoustic impedance values of sandstones with ranges (8000-12000) (m/s)*(g/cc). The results of the gamma-ray multi-attribute, shale volume and porosity, have been shown to consistently show the distribution of sandstones that have a trend in the distribution of NW-SE reservoir zones. From the results of the analysis there are several potential areas that have the potential to become the next development area, namely the distribution of sandstones in the northern part with high effective porosity, and good seals; In the south with a large volume of sandstones; as well as the distribution formed on the channel surrounding the fault.

Abstract
Ambulance is one the most critical component in healthcare where it must have highest reliability and mobility to ensure minimum travel time of patient to the hospital. In Malaysia, there are significant number of cases where ambulance tend to have breakdown or caught on fire due to electrical current overload which caused by unmanaged electrical usage by medical equipment. To overcome this problem, a smart power management system has been developed by employing Hall-Effect based current sensor replacing conventional fuse. The sensor reading is actively analysed by a microcontroller which will cut off electrical power from over-current equipment. The system also can prioritize some critical equipment to be powered when there are limited current available.

Published: July 2020

Abstract
This paper presents results obtained from the application of a computational fluid dynamics (CFD) approach to modelling of non-premixed turbulent ethylene sooting flame. The study focuses on comparing the two soot models available in the Fluent in predicting the soot level in the turbulent non-premixed ethylene flame. A standard k-ε model and Eddy Dissipation model are utilized for the representation of flow field and combustion of the flame being investigated. For performance comparison study, a single step soot model of Khan and Greeves and two-step soot model proposed by Tesner are tested. The results of calculations are compared with experimental data for a turbulent sooting flame taken from literature. The results of the study show that a combination of the standard k-ε turbulence model and eddy dissipation model is capable of producing reasonable predictions of temperature both in axial and radial profiles; although further downstream of the flame over-predicted temperatures are evidence. With regard to soot model performance study, it shows that the two-step model clearly performed far better than the single-step model in predicting the soot level in ethylene flame at both axial and radial profiles.

Published: July 2020

Abstract
Rock drilling and blasting holes created during construction of underground mining in general and in Quangninh are the interaction of the drill into the rock. Drilling efficiency and productivity depend on many parameters such as power dam, the rock solidity and the rotational speed of drilling and geometric parameters of the drill head. These parameters determine and affect the durability of the drill head. In this report, the authors present the results of experimental studies of the influence of sharp angles on the durability of the cross drill head during the drilling process and blasting rock in the Quangninh coal region. According to the results, it is established that the wear intensity f varies positively with firmness i
h and inversely with the sharp angle of the drill head in the range of studied sharp angles. Nevertheless, the variation of wear intensity with regard to the change in sharp angles is not significant compared to the variation of wear intensity according to the rock strength. Research results can be used to calculate, design and choose appropriate drill rock quarry that increases the productivity and efficiency of drilling, contributing to reducing product costs.

Abstract
The article discusses the effect of the remoteness of the place of a three-phase short circuit on the depth of the voltage dip depending on the load on the synchronous generators and synchronous motors. A series of experiments was carried out where the length of the 110 kV overhead power line varies, at the end of which a short circuit occurs, as well as the load distribution coefficient of a synchronous machine with higher than normal field-forcing ratio and the influence of these parameters on the level of residual voltage among large industrial consumers. The efficiency of using synchronous machines with a higher than normal field-forcing ratio of the excitation is estimated, and their stability under a sharp increase in loads, which cause voltage changes during the transition process and cause rotor vibrations, accompanied by magnetic losses due to the occurrence of eddy currents in the rotor core, is considered.

Published: July 2020

Abstract
The paper reviews the issues of source data generation for automated design of the technological process of machining and geometric information transfer from one design stage to another. When dealing with design issues, the input of source data related to the work-piece and manufacturing conditions plays an important role. The formalized description of these objects is carried out using mathematical models. A drawing of a machine-building part or work-piece is a geometric model of the manufacturing item. However, this model is inconvenient when establishing links in the design of its manufacturing processes. Drawing models are the basis of graphic modules of computer-aided design systems. However, they are inconvenient for achieving process design goals, since the object is known to be surface in machining or assembly process, but not zero-dimensional objects on the plane. It represents a mathematical model of a machine-building part consisting of the basic elements of the form, which can be used in the automated development of the technological process of machining.

Published: July 2020

Abstract
The gas of many fields in Eastern Siberia (Chayandinskoye, Kovyktinskoye, Sobinskoye, Chikanskoye, etc.) has a complex component composition with a high helium content. In order to realize the advantage of a unique raw material base, it is necessary to put into practice solutions for the industrial implementation of technologies for the extraction of helium, storage and transportation. One of the directions for the solution of these problems is the creation of temporary underground storage of helium concentrate in a porous medium next to gas chemical plants. This will ensure supply flexibility and reduce helium losses. The global demand for helium is continuously increasing from year to year and in the long term, a favorable situation will emerge on the global helium market for Russia, a positive effect from which can be achieved, provided the benefits of the raw material base are realized. A positive effect means not only the monetary effect, but also takes into account the formation of prerequisites for the development of new spheres of influence: access to new trading platforms and sales markets, the development of high-tech industries, basic and applied sciences, etc. In order to realize the advantage of the raw material base, Russia needs in a fairly short period of time to put into practice the decisions on the industrial introduction of gas separation technologies and underground helium storage.
