Market power or efficiency? An empirical study on the Indonesian fertilizer industry
Authors: Destiartono Mohamad Egi , Purwanti Evi Yulia
Published: January 2022

This article aims to analyze the Indonesian fertilizer industry's market structure, efficiency, and performance determinants. This study applies the Structure-Conduct-Performance (SCP) framework proposed by the Harvard (market power) and UCLA-Chicago School (efficiency structure) schools of thought. We run Data Envelopment Analysis (DEA) and panel data regression to analyze the panel data constructed from annual reports of fertilizer producers in 2008 – 2017 and statistical publications from the agriculture ministry. DEA is a nonparametric method that measures technical and scale efficiencies. Meanwhile, panel data regression estimates the determinants of firm performance (ROA). The results show that the fertilizer industry has market power based on three characteristics; the number of incumbents (five), degree of market concentration (95.48 percent), and barrier to entry condition. Meanwhile, its industrial technical efficiency score is low (0.584), but its scale efficiency score is high (0.950). The results also show that firm performance is determined by efficiency, not market power. Both technical and scale efficiency positively and significantly affect performance. On the other hand, market power does not significantly affect performance. This finding supports the UCLA-Chicago School that efficiency is the main factor of firm performance.

Authors: Pribowo Heru , Fidiana Fidiana , Suryono Bambang
Published: January 2022

This study aims to explore accounding educatos’ consciousness and understanding regarding accounting education from the perspective of Christian spiritual intelligence. Accordingly, we use a phenomenological approach as the research method. Data is generated through conducting in-depth interviews  using epoche to several informants (lecturers of a university in Palangkaraya, Central Kalimantan Province). Data is then analyzed using the transcendental phenomenology approach. The results demonstrate that each informant has spiritual intelligence or divine consciousness. They  also expect that these divine or spiritual values can be integrated into current accounting education to enable future accounting graduates not to be misguided when entering the professional lives and applying their knowledge. We also find three (3) values or meanings contained in Christian spiritual values, namely: fear of God, integrity (a reflection) of God, and heaven. Accountants will exhibit these three values if their education already have divine or spiritual values. In sum, our study underscores the importance of integrating spiritual values into the existing courses, not only ethics-related ones, but also accounting-related ones.
Entrepreneurial orientation and entrepreneurial intention: When more learning exposures are efficacious
Authors: Manik Hardo Firmana Given Grace , Kusuma Airlangga Surya
Published: January 2022

Many business schools in the world seek to create newly aspiring entrepreneurs starting from their university years. Many Indonesian universities also engage in this challenging effort. This study investigates the effect of students’ individual entrepreneurial orientation (IEO) on entrepreneurial intention (EI) through regression analysis and t-test on 200 students from several major Indonesian universities. Our results indicate that all IEO dimensions (i.e., innovativeness, risk-taking, proactiveness, passion, and perseverance) positively affect EI. These findings fill in the gap regarding the IEO studies in other contexts by adding two new dimensions, namely passion and perseverance. Further, this study demonstrates that students who have taken entrepreneurship courses exhibit greater effect of IEO on EI, but only in two dimensions (i.e., risk taking and proactiveness). Besides, students who actively participate in student organizations exhibit higher IEO than those who do not, especially in three dimensions dimensions (i.e., innovativeness, risk taking, proactiveness). Hence, this study underscores the importance of various learning exposures (not only in the classroom) for university students to develop their IEO.

Authors: Jabr Sarah A. , Karam Nada S.
Published: January 2022

In this paper, the reliability of the stress-strength model is derived for probability P(Y<X) of a component having its strength X exposed to one independent stress Y, when X and Y are following Gompertz Fréchet distribution with unknown shape parameters and known parameters . Different methods were used to estimate reliability R and Gompertz Fréchet distribution parameters, which are maximum likelihood, least square, weighted least square, regression, and ranked set sampling. Also, a comparison of these estimators was made by a simulation study based on mean square error (MSE) criteria. The comparison confirms that the performance of the maximum likelihood estimator is better than that of the other estimators.

Authors: Mondragon-Soto Michel Gustavo , Elkaim Lior , Weil Alexander G.
Published: January 2022

Background:

Ventriculoperitoneal shunt (VPS), the mainstay of the treatment for hydrocephalus, is associated with relatively high revision rates. Transient hydrocephalus due to intermittent VPS obstruction should be recognized as a cause of VPS malfunction. While transient VPS dysfunction is well-recognized complication, there is a relative paucity of well-documented cases in the literature.

Case Description:

We present the case of a 4-year-old boy with a history of vascular malformation and hydrocephalus secondary to intraventricular hemorrhage. The patient presented with transient, self-resolving hydrocephalus (without intervention), as documented by clinical and radiological findings.

Conclusion:

Transient hydrocephalus due to intermittent VPS dysfunction in children is a rare entity, but it should be suspected in certain patients with VPS presenting with transient or self-improving symptoms.

The Transitional Gabbroic Rocks in Bayah Geological Complex, Western part of Java, Indonesia, Inferred from XRF, ICP-MS, and Microprobe Analysis
Authors: Patonah Aton , Permana Haryadi , Syafri Ildrem
Published: January 2022

Gabbro, is a fossil remnant of oceanic crust in western part of Java, found at Bayah Geological Complex (BGC) and Ciletuh Melange Complex (CMC), Indonesia. It has been studied by using petrographic, X-Ray Fluorescence (XRF), and inductively coupled plasma-mass spectrometry (ICP-MS) and mineralogical (microprobe) analyses. Mineral and geochemical composition of these rocks provide important clues to their origins since the rocks have been deformed and gone through auto metamorphism, beside they contain the economic mineral and or rare earth elements (REE). Gabbroic rocks in these two areas generally shows phaneritic to porphyritic texture, granular texture. These rocks in CMC are dominated by plagioclase (oligoclase to albite), hornblende, pyroxene, partly altered to tremolite, actinolite, chlorite, epidote, and sericite; meanwhile those of BGC dominantly consist of plagioclase, pyroxene, hornblende, some present of chlorite, actinolite, epidote and biotite as secondary minerals. In multi-element diagrams, gabbroic rocks in CMC show strong negative Sr and Zr, but positive Nb anomaly, while those of BGC show strong negative anomaly of Nb and Zr. In addition, based on rare earth elements (REE) diagrams, gabbroic rocks in CMC show depleted of light rare earth elements (LREE) with negative Eu anomaly, while gabbro’s in BGC show enrichment of LREE. These characteristics indicate that GBC’s and CMC’s gabbroic rocks came from different magma sources, one was formed by partial melting of depleted upper mantle reservoir while the other one was formed by partial melting of mantle wedge with active participation of subducted slab in an arc tectonic setting, suprasubduction zone which were formed at started Upper Cretaceous to Paleogene, and they had retrograde metamorphism to epidote amphibolite facies.

Authors: Gunadi Putra Ullil , Jhanesta William , Iskandarsyah
Published: January 2022

The research was conducted in Bittuang, Tana Toraja Regency, South Sulawesi Province, as one of the geothermal prospect areas and targets for the initial stage of the Government exploration drilling program for the 2020-2024 period. One aspect of geothermal is the manifestation control structure as a fluid migration path from below the surface. Therefore, identification of existing structures in the Bittuang geothermal area was carried out and confirmed the surface geological structure contained in the Bittuang geothermal geological map. In determining the presence of a fault and knowing its characteristics such as the type of fault, the direction of the dip, and the magnitude of the dip of the fault, the gravity data is processed using the multi-level second vertical derivative (ML-SVD) method. To strengthen the interpretation, the results from the ML-SVD were matched with the data from the horizontal gradient (HG) method and the geological data of the structure of the study area. From this process, there are 27 faults in the Bittuang geothermal area, two of which are indicated as controlling faults for the manifestation of the Balla group and the Cepeng group. This research is expected to describe faults in the Bittuang geothermal area, which can support detailed exploration activities.
Urban Expansion and Rising Surface Temperature: A Multi Temporal Assessment in Kochi Metropolis, Kerala
Authors: Arya Lekshmi P.T. , Lancelet T.S.
Published: January 2022

The process of urbanization and urban growth has resulted in rapid, uncontrolled conversion of natural land cover and spreading of impervious concrete surfaces in many parts of the world leading to serious environmental concerns. There are a myriad of micro climatic effects due to urban growth. One of the significant consequences is the rising urban temperature. Urban surface temperature responds to changes in land use/land cover dynamics and urban expansion. This would ultimately lead to local climatic changes and would accentuate global warming. Geo spatial technology provides sophisticated tools for analyzing urban features and micro climates. Land surface temperature (LST) or the radiant energy from earth surface can be calculated using thermal bands of satellite data. Kochi, the largest urban agglomeration in Kerala, is undergoing hasty developments and land modifications. This study attempts to monitor changes in land surface temperature from 2000 to 2020 along with changes in built up and vegetation cover. The results revealed that the average surface temperature of Kochi recorded an increase of 0.60C and the loss of green cover has contributed to the increased temperature. Moreover, the LST exhibits a strong positive correlation with built up land expansion. The study findings stand helpful for urban planning and sustainable development of the city.

Authors: Keshari A.K. , Saxena S. , Pal G. , Srivashtav V. , Srivastav R.
Published: January 2022

A green rapid biogenic synthesis of silver nanoparticles (AgNPs) using Catharanthus roseus leaf extract was performed. Synthesized nanoparticles were characterized using UV-Visible, Fourier transform infra-red (FTIR) and X-ray diffraction (XRD). The reduction of silver ions to AgNPs using C. roseus extract was completed within 240 mins. The formation of AgNPs was confirmed by Surface Plasmon Resonance (SPR) at 442 nm using UV-Vis Spectrophotometer and it is characterized by XRD, Transmission electron microscope (TEM) and Scanning electron microscope (SEM). The morphological studies revealed the spherical shape of the particles with sizes ranging from 16-35 nm and Energy dispersive X-ray (EDX) spectrum confirmed the presence of silver along with other elements in the plants metabolite. The extracellular AgNPs synthesis by aqueous leaf extract demonstrates ultra-fast, simple and inexpensive method comparable to other methods. The antioxidant assay of the synthesized AgNPs indicated that they have a strong antioxidant property as compared to the control. Since these compounds are also safe to use and discharged into the environment, the green AgNPs could be considered as an innovative alternative approach for biomedical and nanoscience based industries.

Published: January 2022

In silico based subtractive genomic approaches were employed to identify the key drug targets for an opportunistic pathogen Nautella italica, a member of the marine Roseobacter clade that causes bleaching disease in the temperate-marine red macro algae, Delisea pulchra. The aim of this study is to propose new active ligands against bleaching disease seen in algae. Using comparative and subtractive genomic approach, a set of 21 proteins were identified as the therapeutic drug target proteins for algal bleaching. This core set of drug targets has been analyzed for network topology using string network analysis and major hub gene identified by CytoHubba was rpoB (DNA directed RNA Polymerase subunit beta). The three-dimensional structure of rpoB was built by comparative modelling and used to perform a virtual screening of Zinc database by DOCK Blaster server. The 50 top scored compounds were screened for toxicity analysis by OSIRIS Data Warrior and ECOSAR tool. Further refinement by autodock program revealed two compounds ZINC49821385 and ZINC97218938 with the best binding energy of -7.07 and -6.79 respectively. These results indicated that 5-(4- isopropylphenyl)furan-2-carboxamide (ZINC ID 49821385) could be one of the potential ligand to treat bleaching disease in algae.

Authors: Phromchaloem C. , Muensritharam L.
Published: January 2022

In general, the laboratory method of analyzing pesticides in vegetables is complicated due to the high cost of equipment and chemicals. The process of analyzing pesticide residues generally requires expertise as well as a significant period of time. In this study, a paper-based biosensor was developed for the detection of acetylcholinesterase (AChE) inhibitors, particularly organophosphate pesticides. The paperbased biosensor was constructed based on the Ellman colorimetric assay by immobilizing AChE on cellulose paper with 2% alginate gel, 0.25% glutaraldehyde and the colorimetric reagent 5,5-dithio-bis-(2-nitrobenzoic acid) (DTNB) in phosphate buffer (pH 8.0). As a substrate, acetylthiocholine chloride (ATChCl) was used. The results showed that the developed paperbased biosensor has been stable for 2 weeks with a detection limit of 0.03 mM of chlorpyrifos. The paper-based biosensor was applied to detect organophosphate pesticides in vegetables from the farmers’ market, Ratchaburi Province. It was found that the test results of the paper-based biosensor were similar to the commercial GT-test kit. The paper-based biosensor was 10 times faster than the GT-test kit in terms of testing time and the results were easy to identify due to the color-based indicator. As a result, a paper-based biosensor is rapid, portable and easy to use by the general population.

Published: January 2022

Novel energy and atom efficiency processes will be keys to develop the sustainable chemical industry of the future. Electrification could play an important role, by allowing to fine-tune energy input and using the ideal redox agent: the electron. Here we demonstrate that a commercially available Milstein ruthenium cata-lyst (1) can be used to promote the electrochemical oxidation of ethanol to ethyl acetate and acetate, thus demonstrating the four electron oxidation under preparative conditions. Cyclic voltammetry and DFT-calculations are used to devise a possible catalytic cycle based on a thermal chemical step generating the key hydride intermediate. Successful electrification of Milstein-type catalysts opens pathway to use alcohols as renewable feedstock for the generation of esters and other key building blocks in organic chemistry, thus contributing to increase energy efficiency in organic redox chemistry.

Published: January 2022

State universities have a library as a facility to support students’ education and science, which contains various books, journals, and final assignments. An intelligent system for classifying documents is needed to ease library visitors in higher education as a form of service to students. The documents that are in the library are generally the result of research. Various complaints related to the imbalance of data texts and categories based on irrelevant document titles and words that have the ambiguity of meaning when searching for documents are the main reasons for the need for a classification system. This research uses k-Nearest Neighbor (k-NN) to categorize documents based on study interests with information gain features selection to handle unbalanced data and cosine similarity to measure the distance between test and training data. Based on the results of tests conducted with 276 training data, the highest results using the information gain selection feature using 80% training data and 20% test data produce an accuracy of 87.5% with a parameter value of k=5. The highest accuracy results of 92.9% are achieved without information gain feature selection, with the proportion of training data of 90% and 10% test data and parameters k=5, 7, and 9. This paper concludes that without information gain feature selection, the system has better accuracy than using the feature selection because every word in the document title is considered to have an essential role in forming the classification.

The Law of Ukraine “On Electronic Documents” and “On Electronic Digital Signature”, which came into force on December 28, 2003 and January 1, 2004, respectively, gave the “green light” to the widespread use of electronic documents and digital signatures in the country. Continuation in the introduction of electronic documents, including electronic signature forms and their use in secure information systems, was the adoption in 2018 of the Law of Ukraine "On electronic trust services" (Law of Ukraine "On electronic digital signature" expired) and a number of bylaws regarding electronic interaction between two information resources (state registers / information and telecommunication systems…) and / or for the provision of administrative services. At the same time, the use of the latest technologies aimed at increasing the efficiency of work creates new risks that can lead to the disclosure of sensitive information, the consequences of which can be critical. To prevent this from happening, the system being created or the existing system must be well protected and comply with the Concept of "Secure Information Systems". This Concept includes a number of legislative initiatives, scientific, technical and technological solutions. Also, it is necessary to refer to the definition of a reliable information system, which is provided in the "Orange Book". According to which, a reliable information system is defined as “a system that uses sufficient hardware and software to ensure the simultaneous reliable processing of information of varying degrees of secrecy by different users or groups of users without violating access rights, integrity and confidentiality of data and information, and which maintains its performance under the influence of a set of external and internal threats. " Today, among the established methods of information protection, a special place is occupied by an electronic signature (both for verifying the integrity of the document, confirmation of authorship and for user authentication).

The dynamics of the increase in the number of vulnerabilities of software and hardware platforms of corporate networks, the accessibility of exploit modules for these vulnerabilities in the Internet and the Darknet, along with the lack of a sufficient number of highly qualified cybersecurity specialists make the problem of effective automation of preventive information protection mechanisms quite urgent. In particular, the basic algorithms for the sequential implementation of exploits embedded in the vulnerability exploitation tools are quite primitive, and the proposed approaches to their improvement require constant adaptation of mathematical models of the implementation of attacking actions. This justifies the direction of this research. This paper considers the issue of forming decision-making rules for the implementation of vulnerabilities’ exploits during an active analysis of the corporate networks’ security. Based on the results of the analysis of quantitative indicators of the quality of the validation mechanism of the identified vulnerabilities and the use of fuzzy logic methods, a fuzzy system was formed, membership functions for each of the linguistic variables were determined and a knowledge base was built, which makes it possible to determine the quality level of the validation mechanism of the identified vulnerabilities based on all available information. At the same time, in order to eliminate the “human factor” of making mistakes when validating vulnerabilities, based on the built fuzzy knowledge base and the established levels of exploit modules’ efficiency, the rules for the implementation of individual exploit modules during an active analysis of the corporate network’s security were formed. Results of research make it possible to create expert systems for diagnosing the effectiveness of the validation mechanism of the identified vulnerabilities of target systems, and also help to solve the problem of the lack of qualified specialists in the analysis and maintenance of an appropriate level of information security of corporate networks.

The number and complexity of cybercrime are constantly growing. New types of attacks and competition are emerging. The number of systems is growing faster than new cybersecurity professionals are learning, making it increasingly difficult to track users' actions in real-time manually. E-commerce is incredibly active. Not all retailers have enough resources to maintain their online stores, so they are forced to work with intermediaries. Unique trading platforms increasingly perform the role of intermediaries with their electronic catalogs (showcases), payment and logistics services, quality control - marketplaces. The article considers the problem of protecting the personal data of marketplace users. The article aims to develop a mathematical behavior model to increase the protection of the user's data to counter fraud (antifraud). Profiling can be built in two directions: profiling a legitimate user and an attacker (profitability and scoring issues are beyond the scope of this study). User profiling is based on typical behavior, amounts, and quantities of goods, the speed of filling the electronic cart, the number of refusals and returns, etc. A proprietary model for profiling user behavior based on the Python programming language and the Scikit-learn library using the method of random forest, linear regression, and decision tree was proposed, metrics were used using an error matrix, and algorithms were evaluated. As a result of comparing the evaluation of these algorithms of three methods, the linear regression method showed the best results: A is 98.60%, P is 0.01%, R is 0.54%, F is 0.33%. 2% of violators have been correctly identified, which positively affects the protection of personal data.

Published: January 2022

Media culture is one of the important factors in the growth of microalgae. Culture medium contains macro and micro nutrition required for the growth of microalgae. Composition of nutrition and nutrition concentrations determine the production of microalgae biomass and nutrient content. The aim of this study is to evaluate the effect of medium composition variation to Scenedesmus sp growth in laboratory-scale in order to get the optimized composition of media for microalgae Scenedesmus sp. This study was conducted in a laboratory scale. The growth medium that were used in this study were: BBL sm, SS, MN, M4N, “Sederhana 2”, and “Sederhana 3” medium. The microalgae that were used in this study were mixed culture Chlorophyceae microalgae which is dominated by Scenedesmus sp. The parameters observed were pH, optical density (OD), cell density and temperature. The results show that of the 6 variations of the growth medium used in this study M4N medium is the best medium for the growth of microalgae. At the end of the operation, cell density of Scenedesmus sp. from M4N medium was 306.83 x 106 cell/mL with a dark green color for the culture. The coefficient growth of Scenedesmus sp. which is grown in M4N medium was 0,36. This is likely to be due to the composition of nutrients in the medium M4N which were more complete than other media.

Published: January 2022

Pore pressure estimation in hard-overpressure zone is very important in drilling activities. Correct and precise estimation are able to reduce the cost for drilling due to reduced non-productive time (NPT) and in increase in safety aspect while drilling. Pore pressure estimation is done by post-mortem analysis in exploration wells using validation points from pressure measurement data such as Drill Stem Testing (DST), Modular Dynamic Tester (MDT), and Repeat Formation Tester (RFT). A wireline logs data used for identification of the type of overpressure and predicts pore pressure magnitude in the shale section. Through the correlation between effective-stress and velocity, a single compaction equation was obtained for the Lower Kutai Basin with the value of : 5.097 * ? 0.854. By using this single equation, pre-drill pore pressure prediction activity will be more easy and could estimate pore pressure in hard-overpressure zone precisesly.

Peptides and their derivatives can be applied in enhanced oil recovery (EOR) due to their ability to form an emulsion with hydrophobic molecules. However, peptide research for EOR application, either theoretical or computational studies, is still limited. The purpose of this research is to analyse the potency of the X6D model of surfactant peptide for EOR by molecular dynamics simulations in oil-water interface. Molecular dynamics simulation using GROMACS Software with Martini force field can assess a peptides ability for self-assembly and emulsification on a microscopic scale. Molecular dynamics simulations combined with coarse grained models will give information about the dynamics of peptide molecules in oil-water interface and the calculation of interfacial tension value. Four designs of X6D model: F6D, L6D, V6D, and I6D are simulated on the oil-water interface. The value of interfacial tension from simulation show the trend of F6D L6D I6D V6D. The results indicate that V6D has the greatest reduction in interfacial tension and has the stability until 90C with the salinity of at least 1M NaCl.

Although revenue from the oil and gas industry is no longer the main source of national income, it is still playing a strategic role. The oil and gas industry is known as a high-tech, a high-risk, and a high-capital industry, on which the country has limited capacity for regional development, especially of the resources in areas located along the national border. The main objective of this research is to closely identify the recent growth centre status of blocks and sedimentary basins located along the national border. The study relies on published reports, studies, and data such as bathymetry map, national geographic and jurisdiction map, and maps of existing oil and gas blocks. All data were managed under a geographic information system application in order to conduct comparative and qualitative analysis of those overlaying data. Some oil and gas blocks that are located near to neighboring countries, such as Singapore, Malaysia, Brunei, Vietnam, The Philippines, Papua New Guinea, East Timor, and Australia have been categorized based on these methods of scoring and ranking analysis to identify new economic centres of growth. Three categories are suggested: very important, important, and ordinary as new growth centres. The Natuna Sea blocks, Iwur, and Timor blocks are considered to be important.
