Laser processing over a large area by wavefront-controlled scanning
Authors: Du Xinpeng , Rahaman Arifur , Kar Aravinda , Chase Michael , Wolfe Dave , Mathy John , Yu Xiaoming
Published: February 2021

In the processing of laser materials, the scanning area is limited by the extent to which the laser focus can be maintained within a plane. In order to increase the processing area, one has to enlarge the size of the laser focal spot, and, therefore, reduce the peak intensity and spatial resolution. In this paper, the authors report on a method that extends the processing area by controlling the wavefront of a laser beam using adaptive optics. By adding Zernike modes to the laser beam wavefront, the axial (along the beam propagation direction) location of the focal spot can be tuned within a range larger than the confocal length (two times the Rayleigh length), while the lateral spot size (and, thus, peak intensity and resolution) is maintained throughout the tuning range. A wave propagation model that simulates the propagation of a wavefront-controlled beam is used to compare with the experimental results, which are also confirmed by Zemax calculation. Laser trepanning of circular holes with consistent size on a wide polypropylene sheet is demonstrated. This work shows the potential of tailoring the phase of a laser beam for improving the accuracy and throughput in large-area laser processing of materials.

MANHAJ IJTIHAD PADA ASPEK POLITIK
Authors: Adminqaumiyyah Adminqaumiyyah
Published: February 2021

This article discusses the application of the manhaj or the ijtihad method to the political aspects of the state. The focus of the problem is, can ijtihad be applied to the political aspects of the state, not only to the aspects of fiqh or religious law? Some Muslims still understand that the position of ijtihad is limited to the aspect of fiqh alone. for example, matters of the law of religious observances, marriage and other social institutions). During the period of the Prophet Muhammad, when he moved to Medina, the Prophet made a political commitment as a nation and state involving various ethnic, ethnic and religious layers in Medina. This political commitment is called Shahifah Madinah or Watsiqah Madinah (Medina charter), which consists of 47 articles as the basis for living together with the nation and state. Until now, in a very modern world, the Medina Charter is still considered the most modern political monumental ijtihad ever practiced by the Prophet Muhammad. Based on the above thought background, ijtihad can be used as a method of approach in formulating the concepts of state politics.

As a form of government in which the people who are sovereign and in power to determine their lives, democracy not only provides a breath of fresh openness and freedom but also promises a million hopes for a prosperous people's life. However, in line with the history of mankind, the government system that is predicted to be the best model of government from the worst, are also not free from problems, criticisms and crises that occur in it. The sovereignty of the people which has become the spirit of democracy has been eroded by the problem of the crisis of representation and direct involvement of the people in policy making. Democracy as a model of government reaps a crisis of public confidence which starts to regard this government system as an illusion of prosperity and justice. Interestingly, in the midst of the storm of problems that have plagued the democratic governance system in the present era, a breath of a new fresh air has emerged for the continuity of the sovereignty-based government system. In the city of Porto Alegre, Brazil, which is one of the main countries in the Latin American region, alternatives for strengthening participatory democracy have emerged through a model of governance based on Participatory Budgeting. "The implementation of this Participatory Budgeting has turned out to be able to restore the vital role of the people in policy making while at the same time improving the model of modern democratic governance which is increasingly hit by a crisis of trust and legitimacy from the people of today." Keywords: Democracy, crisis of representation, alternative democracy, participatory budgeting
Plugging the Brain Drain: The Role of Indonesia Diaspora Network towards Indonesian Citizens in Overseas Policy
Authors: Afifi Elfinur Dinny
Published: February 2021

This paper will start from the shifting of brain drain as phenomena and terminology, from traditional (nasionalist) to comprehensive (globalist) thought. The nationalist tends to envisage brain drain as negative impact to source countries while the globalist assumes the ‘brain’ is not drained but circulated and their roots will be embeded as part of their identities. By choosing Indonesia as the case study, this paper will try to analyse about how the brain drain issue related to Indonesia Diaspora Network (IDN) and how the network of IDN works to influence the homeland government with the globalist thought. The Indonesian President Decree No. 76 on 2017 regarding Facilities for Indonesian Citizens in Overseas (Masyarakat Indonesia di Luar Negeri – MILN) designated, on this paper, as new milestone of attainment to Indonesian Diaspora official recogniztion, which enclosed to mission of Indonesia Diaspora Network Global (IDN Global) since its established on 2012. Using the theory of Transnational Advocacy Network by Keck and Sikkink, combined with argument of Sara Kalm on Diaspora Strategies as Technology of Citizenship, this paper argues that the launching of the policy shows that: (i) the role of diaspora network as principal actor who spreads and infused the globalist thought to the government, Indonesia citizens in home countries, and collecting international support, (ii) involving Diasporas in policy making process could be a good strategy for Indonesian Government to instill and strengthen diaspora’s emotions of national obligations, which will also plug the ‘drain’ and maintain to circulate the ‘brain’. To enrich and emphasize these arguments, some literatures of state-diaspora relations will also be applied.
Loss prevention and safety improvement in the mining industry: main directions
Authors: Chmykhalova S. V.
Published: February 2021

Preventing losses and reducing possible hazards is the most urgent and important task in mining. Implementation of this task occurs throughout the entire life cycle of mining production, starting from the development of project documentation and ending with the stage of modernization or liquidation of spent mining production. For mining production as a dangerous production facility [1], it is necessary to develop a modern methodology for risk assessment, accident identification for subsequent analysis, development and implementation of measures to reduce it in the production process. To solve this problem, the most promising method is the analysis of technogenic risk, which must be developed in relation to mining facilities. methods and means of mining. Mineral resources are part of the natural environment, the impact on the natural environment is provided by technical equipment and technological processes necessary for the extraction of minerals [2]. For risk analysis, mining production must be represented as a complex system consisting of the following subsystems: natural; technological; technical; organizational, social, psychological, etc. This study examines natural and technological risks. For each subsystem, factors affecting the probability of accidents and the amount of expected damage are analyzed, and then measures to reduce the risk are proposed. Risk assessment should be part of a comprehensive approach to business management. A systematic and comprehensive approach to risk assessment will allow you to take possible measures to eliminate (reduce) the risk. A systematic approach to risk assessment helps to prevent losses and improve safety in the mining industry by taking better account of possible situations, identifying those responsible for the risk, prioritizing the urgency of execution, and evaluating the risk justification scale.
Methodical principles for improving the ecological and technological reliability of urban underground structures
Authors: Kulikova E. Yu.
Published: February 2021

Construction processes and construction conditions are never repeated. Therefore, a method for improving environmental and technological reliability, which is applicable to the development of underground space, is necessary. Improving environmental and technological reliability in the development of the underground space of cities should be based on the reliability of the construction technologies. Systematization and analysis of world experience in the use of various combinations of construction technologies that increase the reliability of construction of underground facilities is an urgent scientific task, the solution of which allows increasing the efficiency of underground space development. Modern experience of underground construction expands the range of possibilities for improving the reliability of underground space development, based on the use of various underground construction technologies. Thus, the design of the head part of the tunneling boards is being improved, and the range of conditions for their use is increasing from inhomogeneous unstable soils to fragmented rock formations. The technology of micro - and mini-tunneling for laying pipelines for various purposes is becoming widespread. In almost any mining and geological conditions and at any depth, the new Austrian method of tunneling is used. Methods of soil strengthening aimed at reducing the risk of precipitation of the earth’s surface in urban conditions are being improved: chemical reinforcement, jet-grouting, etc. The role of monitoring of deformations and sedimentation of the earth’s surface in the area of underground object placement, its scientific support at all stages of the life cycle, and measures to minimize all types of risk is increasing.
Dust distribution at a coal shearer in the face area
Authors: Kobylkin A. S.
Published: February 2021

Compliance with the Federal Code on Safety in Coal Mine, §22, No. 550 as of November 19, 2013 (as edited on January 1, 2020) dictates air dustiness and dust deposition control to be implemented in mines using stationary and mobile facilities. Application procedures of stationary controllers should be science-based and tested to provide reliable information. In particular, the procedures should indicate installation sites for the controllers and dictate revaluation of readings received from the controllers towards the dust explosion prevention in mines. Aimed to develop a framework for such procedures and to revise measurement areas for the movable controllers, dust distribution in roadways was studied. The studies have found out that particulate emission and dust distribution in the face area is complex due to mobility of the source of dust in the coal face area. Characteristics of dust particles govern their behavior in air flow. Thus, it is required to know characteristics of dust particles at the dust emission point to track their travel in roadways. A dust sampling procedure was developed to sample dust at a coal shearer. The data on characteristics of dust particles were also obtained. The mine and laboratory test results were used as the initial and boundary conditions in computational modeling. The mine researches and the modeling show that air flow is split into two parts in longwall. Dust produced by coal cutting by the shearer moves with air flow above the armored face conveyor. These results highlight the importance of taking into account local and head drags when selecting installation sites for controllers of air dust content and dust deposition in coal mines.

Published: February 2021

The subsidized gasoline conversion to LPG 3 kg in 2006 became the Indonesian Government’s policy to reduce reliance on fuel oil. The increasing LPG consumption and obstacle distribution have been the scarcity of the LPG in all regions of Indonesia. The gasoline fueled stove has overcome from the LPG scarcity.  The purpose of this research was to compare the use of Gasoline types Pertalite and Pertamax with the use of LPG fuel. The research method was carried out by comparing the three types of fuel in the process of boiling 1 (one) litre of water using a gas stove, with several variations in pressure from 1.5 kPa to 2.5 kPa. The results showed that the highest fire temperature for Pertalite was 430 °C fuel, Pertamax 530 °C fuel and LPG 578 °C fuel. Fuel consumption for Pertalite 0,025 kg, Pertamax 0,027 kg and LPG 0,061 kg. The boiling time is 682 s for Pertalite, 669 s Pertamax and 503 s for LPG. The least compaction efficiency value occurs at 1.5 kPa pressure, for Pertalite 6,136 %, Pertamax 7,730 % and LPG 9,018 %. The higher the pressure, the greater the maturity efficiency, instead the fuel consumption and water boiling time are reduced. The cost used to boil water at Pertalite is Rp. 236,-; Pertamax Rp. 251,- and LPG is Rp. 309,-.

Authors: Anggriani Andi Dian Eka , Baso Suandar
Published: February 2021

Designing the form of the ship stern hull could have some impacts on the efficiency of ship propeller and the requirement of the ship speed. Therefore, stern hull form of a ship matched to its propeller and engine power is important consideration in preliminary ship design stage. The main objective of this study is to investigate ship performance by matching the stern hull shape to the propeller diameter and engine power toward high speed. This study was conducted by free running model test and Maxsurf Resistance application. The stern forms were employed U-shape and V-shape. In addition, the fixed pitch propeller (FPP) with three blades was used and the diameter is varied into three sizes 0.032 m, 0.040 m, and 0.048 m. The results show the increase of propeller diameter increases model’s speed for both U-shape and V-shape stern and the effect of the propeller diameter on the speed could be described by using the equations of second-order polynomial. The optimum propeller diameter could be determined taking into account stern hull form, stern shape, tip clearance, and proper speed where then propeller diameter related to draft is given by 0.79T with tip clearance 10%Dp for both U-shape and V-shape. The ship resistances of U-shape stern at Fr 0.221 and V-shape at 0.208 are obtained approximately 89.797 KN and 77.10 KN respectively. Furthermore, the powers of ship for both U-shape and V-shape at those Fr are obtained 904,374 KW and 726,807 KW respectively. Finally, the best stern hull form matched to propeller diameter and engine power is selected and given by U-shape stern.
Analysis Of Form Coefficient For Measuring Gross Tonnage Of Wooden Ship Based On Domestic Meansurment Method Of Indonesia
Authors: Amal Habibi , Asri Syamsul , Ardianti Andi , Baso Suandar
Published: February 2021

Most of the traditional wooden boats in Sinjai and Bone Districts were measured using the domestic measurement method, ship owners with sizes <GT 7 and <GT 30 refused to verify their vessels. Ship owners feel disadvantaged in terms of policies, permits, landing fees, subsidized fuel rations and so on. This study aims to determine the characteristics of the size and shape of traditional wooden ships, analyze and compare the results of the calculation of the gross tonnage (GT) of the ship which is calculated based on the actual size and shape of the ship (real body) with the ship calculated using domestic measurement methods and compiling mathematical equations in determining the value of the ship volume factor based on the main size to calculate the GT. The data processing method was carried out by using the Slovin technique with a population of 49 ship data for the determination of the minimum sample and then entered into the interval class. The results showed that the traditional wooden ships in Sinjai and Bone Regencies have geometric characteristics that are not much different from one another, but the main sizes are quite varied. The larger the main size of the ship, the greater the difference in GT calculations when using the volume factor value based on the domestic measurement method compared to using the volume factor value generated by real body calculations. The formula for the volume factor value (Cb or f) = 0.238 Log ((LBH)1/3) + 0.5134 can be used to determine the volume factor, especially for ships operating in the Sinjai and Bone Regencies as well as an initial reference for measurements by measuring experts ship so that moderate measurement results are obtained.

This study aims to reveal the lifting power of the bamboo raft in holding the weight of the house on stilts so that it stays floating on the water. This research was conducted on the shores of Lake Tempe, precisely in Laelo Village, Tempe District, Wajo Regency. The method used in this research is a field study to determine the real situation in the field so that the real condition of the floating house is known. Furthermore, calculating the load used on the floating house based on the results of field studies. The final stage of the research is to test the raft lifting capacity of the floating house. The data will be analyzed according to Archimedes' Law, so that it can be seen that the bamboo raft can stay afloat even though it is given an Architectural building as heavy as a simple stilt house. The results of this study revealed that the average number of bamboos used as a raft was 175 stalks, and the mean diameter of bamboos was 7.67 cm or 0.077 m. It is known that the volume of the rod segment cavity is 0.103 m³, so the total volume between sections on the floating raft on Lake Tempe is 18.058 m³. The lifting capacity of bamboo rafts is directly proportional to the volume of bamboo joints used as rafts. The experimental test results obtained revealed that the lifting capacity of bamboo per m3 was 874.51 kg, so the lifting capacity of the bamboo raft in Tempe Lake was 18.058 m³ x 874.51 kg / m³ = 15,789.13 kg. While the results of the calculation of the burden of a simple house are known by calculating the house's own load and the living load experienced by the house, and the weight of the house is 9,314.121 kg. With the ability to lift a bamboo raft of 15,789.13 kg, the difference between the lifting capacity of the bamboo raft and the weight of the floating house is 6,475.01 kg. The ideal number of bamboo culms is 129 with a safety factor of 25%. There is an efficient use of 46 bamboo sticks.

Synthetic plugs are available to understand oilfield properties and the behavior of oil in reservoirs where natural plugs cannot be extracted. Specifically, in cases where it is necessary to reproduce representative mineralogical and petrophysical characteristics from carbonate reservoirs, it is evident that there is a lack of publications focusing on synthetic plug construction. In this work, a methodology to construct synthetic carbonate plugs is proposed using disintegrated carbonate rock with controlled particle size, mixed in different weight fraction, uniaxial compaction with controlled load force velocity, pH, temperature, and bonding materials. Preliminary analysis of consolidation (basic consolidation and consolidation by water immersion test), wettability (contact angle measurements) and petrophysical properties (nitrogen expansion porosimetry measurements and theoretical porosity calculation) are reported in this study to determine which composition of the synthetic samples provides similar properties compared to that expected for natural rocks from carbonate reservoirs. Two compositions are recommended to construct synthetic samples: Composition 1 with a total quantity of 100 g of base material (50% w/w of <20 μm, 50% w/w of 20–74 μm) + 5% w/w of amide wax (relative to 100 g of base material) + 6% w/w (relative to 100 g of base material) of pH 3 hydrochloric acid solution; and Composition 2 with a total quantity of 100 g of base material (50% w/w of 150–300 μm, 50% w/w of 300–600 μm) + 5% w/w (relative to 100 g of base material) of amide wax + 6% w/w (relative to 100 g of base material) of pH 3 hydrochloric acid solution. In addition to the compositions, it is necessary to follow the reported procedure based on the uniaxial compaction with controlled load force (200 kN) and velocity (25 mm/min) and the sample’s drying temperature of 100 °C for 1 h aiming to obtain similar samples. These preliminary results will guide further dedicated petrophysical and wettability analysis to deeply understanding these sample’s properties and enhance the construction of synthetic samples more similar to the natural rocks from carbonate reservoirs.
Analysis of well testing results for single phase flow in reservoirs with percolation structure
Authors: Shahrian Elahe , Masihi Mohsen
Published: February 2021

Constructing an accurate geological model of the reservoir is a preliminary to make any reliable prediction of a reservoir’s performance. Afterward, one needs to simulate the flow to predict the reservoir’s dynamic behaviour. This process usually is associated with high computational costs. Therefore, alternative methods such as the percolation approach for rapid estimation of reservoir efficiency are quite desirable. This study tries to address the Well Testing (WT) interpretation of heterogeneous reservoirs, constructed from two extreme permeabilities, 0 andK. In particular, we simulated a drawdown test on typical site percolation mediums, occupied to fraction “p” at a constant rateQ/h, to compute the well-known pressure derivative (dP/dlnt). This derivative provides us with “apparent” permeability values, a significant property to move forward with flow prediction. It is good to mention that the hypothetical wellbore locates in the middle of the reservoir with assumed conditions. Commercial software utilized to perform flow simulations and well test analysis. Next, the pressure recorded against time at different realizations and values ofp. With that information provided, the permeability of the medium is obtained. Finally, the permeability change of this reservoir is compared to the permeability alteration of a homogeneous one and following that, its dependency on the model parameters has been analysed. The result shows a power-law relation between average permeability (considering all realizations) and the occupancy probability “p”. This conclusion helps to improve the analysis of well testing for heterogeneous reservoirs with percolation structures.

Homogeneous open quantum walks on the line: criteria for site recurrence and absorption
Authors: Jacq Thomas S. , Lardizabal Carlos F.
Published: February 2021

In this work, we study open quantum random walks, as described by S. Attal et al.. These objects are given in terms of completely positive maps acting on trace-class operators, leading to one of the simplest open quantum versions of the recurrence problem for classical, discrete-time random walks. This work focuses on obtaining criteria for site recurrence of nearest-neighbor, homogeneous walks on the integer line, with the description presented here making use of recent results of the theory of open walks, most particularly regarding reducibility properties of the operators involved. This allows us to obtain a complete criterion for site recurrence in the case for which the internal degree of freedom of each site (coin space) is of dimension 2. We also present the analogous result for irreducible walks with an internal degree of arbitrary finite dimension and the absorption problem for walks on the semi-infinite line.

Published: February 2021

A modular one-pot synthesis yielding tetracoordinated-N,N,N,N-copper(I) complexes bearing imine and diimine ligands was developed. Copper aids the condensation of a pyridine or imidazole carbaldehyde with a biphenyl amine and even stabilizes labile ligands. Tetradentate and bidentate ligands were formed, the latter forming homoleptic CuL2 complexes. The identity and purity of the compounds were assessed by NMR, elemental analysis and mass spectrometry. The interconversion of different species in solution was studied by variable temperature NMR. The complexes aim to mimic the histidine copper brace of lytic polysaccharide monooxygenases (LPMOs) and bond lengths obtained from XAS and single crystal XRD for the complexes were compared to reported photoreduced LPMOs.

Copper- and nickel-porphyrin complexes show extremely weak axial coordination ability without any electron-withdrawing groups. Herein, we report axial ligation on CuII- and NiII-porphyrins in a highly rigid cofacial porphyrin dimer with a bidentate ligand, 1,4-diazabicyclo[2.2.2]octane (DABCO). To the best of our knowledge, this is the first report on the use of CuII- and NiII-porphyrins for coordination-induced guest binding of porphyrin-based host molecules without the help of other metal ions. The high rigidity of the dimer induces guest binding through the cooperative effect of weak axial ligation. The results showed that CuII- and ZnII-complexes bind one DABCO molecule inside their cavities, whereas the NiII-complex binds two additional DABCO molecules outside to form a stable 6-coordinate paramagnetic NiII-complexes.
