Fractional Current Flow in the Subsurface Using Electrical Resistivity Method: A Laboratory Approach
Authors: Adegoke James Adeyemo , Layade Gideon Oluyinka , Kadir Temitayo
Published: April 2021

The authors describe electrical resistivity method using a laboratory experiment, which was conducted in order to calculate the percentage of current that penetrated each layer of soil arranged in a container using Schlumberger array. Four soil samples arranged in three different set-ups were used. The apparent resistivity obtained was interpreted using curve matching techniques and WinResist iteration yielding types A curve, H curve and A curve, respectively. The interpreted data gave the resistivity of each layer and its thicknesses. The thicknesses obtained from the interpretation were at variance with the actual thicknesses arranged in the container. A multiplier was obtained which serves as a constant in other to obtain the actual thickness. The effective penetration depth of current was determined through the calculated thickness of each layer and the known electrode spacing (AB). The percentage of current that penetrates the layers was found to depend on the electrode spacing as well as the thickness of that layer. Thus, a layer with relatively small thickness has a small percentage of current passing through it compared to a thicker layer.
Differences in Exchange Rate Effects on Production Growth: the Case of Iranian Industries
Authors: Sajad Ebrahimi , Omid Ghaderi , Saeed Bayat
Published: April 2021

There has been a long debate about whether exchange rate depreciation promotes output growth or not. In this context, we use Iran’s foreign exchange market which has had large fluctuations in recent years. Since the exchange rate influence on industries’ activity through different mechanisms, we examine the exchange rate effects in the industry level. To do this, the Iranian manufacturing industries data at 4-digit ISIC level are used from 2011 to 2017. The results of GMM dynamic panel data estimations show that the effects of real exchange rate depreciation on average, are positive in the non-crisis periods. But this relationship does not remain valid in a currency crisis conditions. Accordingly, depreciation does not have any positive effects during the currency crisis. Also, estimation results indicate the exchange rate volatility negatively affects industrial production in all periods. Our findings confirm that due to different characteristics of industries, the effects of exchange rate on production vary among them. So, export orientation, access to the preferential rate and higher level of raw material inventory amplify the positive effect of the real depreciation while import dependency and a higher level of final goods inventory fade the effect and turn into negative in some industries.

Published: April 2021

Organizational culture and job satisfaction are the most important factors for any university. Research into how satisfied professors are with university culture is crucial in finding ways to increase job satisfaction in the present as well as the future. The aim of our study is to investigate whether the type of organizational culture has any effect on job satisfaction and whether there are any differences between Serbia, Slovenia, and Bosnia and Herzegovina. The study was conducted on 489 professors at universities and colleges in Serbia, Slovenia, and Bosnia and Herzegovina. The study shows that university professors in the three investigated countries have a moderate level of job satisfaction. The case study method was used. The data collection technique applied was a survey conducted among university professors. The survey was conducted electronically, via Google Forms, and the key instrument was a questionnaire. The data were processed using SPSS Statistics 21. The results of the study show that improving perceived organizational support can increase the level of job satisfaction of university professors. It is also very important to emphasize the importance and originality of this study since similar studies have not been conducted before in the three countries mentioned.
Cluster Analysis of Regional Research and Development Disparities in Europe
Authors: Ionela-Andreea Puiu , Marian Necula
Published: April 2021

The European continent distinguished as an entity with genuinely regionalized economic structures. Considering the existing economic disparities in the European regions were found several reasons for the regional aggregation of research and innovation activities.Our study aims to assess the European region’s total factor productivity performance of knowledge production for the period 2009-2018, proposing to identify several clusters in the European countries based on their innovative potential and their total factor productivity. The present research evaluates the performance of regional knowledge production in the European countries by using the Malmquist Index procedure. We expect to assess the efficiency of research and development inputs in knowledge production and the contribution of the total factor productivity to the innovative capacity building. The source of data was the Eurostat database. To estimate the knowledge production achievement in the European countries, we examined the total research and development expenditures and the number of researchers involved in this activity as conventional inputs in determining the Malmquist Index. As output, we considered the number of patents applied at the European Patent Office. We applied cluster analysis to identify potential factors that determine disparities among different levels of development of innovation capacity and to detect similarities within the identified clusters.
Tree growth and survival over 61 years at the Second International Larch Provenance Test in southeastern Michigan, USA
Authors: Kashian Daniel M. , Barnes Burton V.
Published: April 2021

Provenance trials remain an important tool for understanding genetic variation in forest trees. Maintaining decades-old experiments is critical for revealing maladaptation of translocated populations to local sites and meaningful divergence in survival and growth. We revisited the Second International Larch Provenance Test in southeastern Michigan, which featuring 24 provenances of European and Japanese larch. We compiled data collected when the plantation was 25, 41, and 61 years from seed to supplement data published at 19 years from seed. Divergence in survival rates first became pronounced at 41 years from seed. Plantation sources of unknown origin and continental Sudeten provenances had the highest rates of survival. High-elevation sources from the southern Alps performed the poorest. Survival differences were likely driven by ice storm damage and severe growing season droughts, both of which occurred at least 1-2 times per decade in southeastern Michigan over the last 60 years. Provenance performance for growth mirrored that of survival, although sources varied more in their survival than in their growth. Growth rate among sources varied over the 43-year sampling period, with intervals of fast growth occurring in several of the overall poor-performing provenances. Diameter was moderately correlated to both elevation and latitude, with inconsistent correlations to climatic variables. Broad geographical variation in provenance performance was also important in explaining variation in growth. Our data corroborate that monitoring of long-term provenance trials could be an important source of information needed to predict and understand how forest species may respond to imminent climate change and may be critical for developing strategies for its mitigation.
The Fate of Mid-20th-Century Sports Loanwords from English in Polish
Authors: Dylewski Radosław , Bator Magdalena
Published: April 2021

In recent years, we have observed a huge influx of vocabulary borrowed from English into Polish; these are words either of English origin or borrowed through English. At the same time, the number and variety of scholarly investigations trying to illustrate the extent of anglicisms in Polish and systematise the semantic fields which draw from English the most have increased. Most of them deal with the latest borrowings, often representing professional jargon or spoken language.

In this paper we will discuss anglicisms which entered Polish over sixty years ago and remained in the sports lexicon until today. The article is a tribute to the late professor Jacek Fisiak, who offered the first in-depth analysis of sports vocabulary borrowed from English into Polish. His Ph.D. monograph (1961) and the subsequent article (1964) have shown a special place of sports terminology among anglicisms in Polish. The lexical items which Fisiak collected in the early sixties of the twentieth century have been tested not only in terms of their fate, but also the degree of grammatical and orthographic assimilation, as well as semantic changes the lexemes have undergone. The study is based on two large corpora of Polish: the Narodowy Korpus Języka Polskiego and Odkrywka, comprising texts from the 18th century until the present time.

Thespesia populnea is a coastal evergreen tree species which flowers seasonally. The flowers are hermaphroditic, self-compatible, self-pollinating, and principally melittophilous. The fruits are indehiscent, turban-shaped, capsules, which release seeds in tidal water upon the decay of their pericarp. Both fruits and seeds are buoyant and typically hydrochorous. This species is a source of wood, dye, food, traditional medicine, being also used as an ornamental and avenue tree. Therefore, it is important in coastal eco-restoration and carbon sequestration.
Prototype Hermetic Teachings: Hermes Trismegistus and Three Hermes
Authors: Vinokurov V. V.
Published: April 2021

The paper treats the topic of hermeticism — an esoteric tradition of teachings — with the view to its origins and varying interpretations. In setting research objectives, the text aims at identifying the common structural foundations of myths and ideas of the hermetic genesis and to establish the main vectors of the formation and transformation of esoteric teachings presented in the spiritual domain and reflected in the material culture of Western Europe from the 4th century BC to the present. For the needs of such a comparative study that embraces philosophical, religious and historical phenomena of culture, the following methods are used. As it is mostly the texts that are analyzed, the methodological framework consists of the interpretation of texts and artifacts – all along the line of presentation of historical sequences, of their recursion, of structural and functional aspects. The sources included not only texts, mathematical operations and chemical formulas of previously known alchemic artifacts are also introduced into the comprehensive analysis. The examination of cultural phenomena leads to the systematization of religious origins, historical and philosophical traditions and scientific achievements that underlie the formation of hermeticism. This structuralisation is possible due to the tools for the analysis of the hermetic body developed in this text. The mapping of the historical development of hermeticism is proposed in a three-level paradigm model based on the image of the Thrice-Great Hermes. It is concluded that the basis of the image of Hermes is the invariant of the historical three-level model of cognition of esoteric teachings, for descriptions of which the terms of ABC — paradigm are introduced. Each of the Hermea has own disciplinary paradigm. The first level of Hermes I, the author of cosmogonic visions, A — paradigm, is represented by inner visions (revelations of the cosmic mind or daimonic visions), thus forming the cultural level of mythology, theology. The level of Hermes II, the founder of writing and counting, lies in the realm of concepts of visions ‒ e.g. the Platonic philosophy, geometry, mathematics (B — paradigm). The third level (C — paradigm) is represented by texts and alchemical artifacts (Alexandrian crystal) of Hermes III, the founder of the art of healing and chemistry, that further embodied in empirical sciences, chemistry and astronomy, as well as ancient technological knowledge of the production of metals, glass and dyes. In general, all hermetic disciplines and practices emerge on the basis of this three-level paradigm.
The History of the Becoming of the Self-Conscious Soul as the Culminating
Authors: Koshemchuk T. A. , Bondarev A. V.
Published: April 2021

The article dwells on the amalgam of meanings and interpretations that have arisen in connection to Andrei Bely’s major work of the 1920s The History of the Becoming of the Self-Conscious Soul. This paper is dedicated to the first complete edition of this literature and philosophical piece that took place in 2020, two decades after the book was first — and partially — published in 1999. The very process of publishing and the temporal gaps that marked the stages in the life of this work is important for better understanding of the trends in interpreting the motifs and concepts of Bely. This study anticipates the inconsistencies of various attempts to understand the conceptual mechanism of Bely and thus has the scope of clarifying such concerning takes and contrasting them to the ways of addressing conceptual issues that Bely uses in his entire oeuvre. With the 1999 publication fueling interest to the self-conscious soul, it represented, however, just a first approximation — and this one, quite incoherent in interpretations, should be amplified towards a fuller elaboration. The analyzed corpus of secondary literature reveals that in a few articles devoted to main ideas of The History of the Becoming of the Self-Conscious Soul there are numerous inaccuracies of perception and reinterpretation even in the basic concepts. For better understanding of Bely, it is fruitful to consider his ideas not from outside worldview positions. Quite the opposite, do it with the view to internal consonance, to anthroposophical foundations. Otherwise, misunderstanding of such concepts as culture, individual, I, personality, self-consciousness is inevitable. The article notes a number of features of their modern perception. First, these concepts are taken not in the dynamic, variable, gradational way, but in a rational and static way, with one or more meaning torn out of the variation series. Further, Bely, contrary to his own judgments about the Steinerian foundations of his work, is considered to have various influences and parallels, based on external similarities. Finally, Bely’s anthroposophical ideas themselves are reinterpreted and radical differences in comparison with anthroposophy are found. The article also reveals fruitful judgments about the essence of The Нistory and examines first of all the articles of Karen A. Swassjan who examines Bely’s history of culture as a personal history of the formation of consciousness — as material for a biography.
Intensifying the Assimilation of Indians in the Сontext of Implementing the Indian Act
Authors: Timofeev V. V.
Published: April 2021

The article examines the policy of Canadian authorities toward the indigenous population (Indian policy) within the framework of implementing the Indian Act. The analysis concerns the policies from the second half of the 19th century to the beginning of the 20th century and the long-lasting effects of those, which remained existential in the second half of the 20th century, the Oka crisis in particular. The literature shows it is necessary to identify the whole range of the factors that determined the implementation of assimilationist policies and to trace the influence they had on subsequent events in the historical perspective. To provide a comprehensive outlook, taking into account such processes as territorial consolidation, colonization and demographic tendencies, the research is based on inductive assumptions. The central assumption why such policies arose is the demographic factor, being the key cause of the inter-racial and inter-ethnic imbalance. This, in turn, provoked the assertive stance taken by the political elites toward the indigenous. It is due to the Anglo-Saxon chauvinism that shaped the attitudes of the Canadian elites and thus became the ideological trend of the late 19th ‒ early 20th century Canada. The Anglo-Canadian nationalists’ intention to ensure the predominance of the Britishness element in the emerging Canadian society is demonstrated to have stemmed from the transatlantic ties with the former metropole. The discriminatory measures taken under the Indian Act that were explored in the text demonstrate that the processes of the Canadian state’s evolution and the ideological tendencies were marred by innate discrimination. The connection between the political measures implemented in the past and the current situation is considered. The Indian policy laid down the foundation for the inter-ethnic tensions that can manifest themselves in modern Canada. The Oka crisis of 1990 serves as the example. The scientific discussion of the effects of the Indian policy and of that particular case that involved the indigenous population and the military was analyzed, and alternative perspectives perceiving the Canadian soldiers as peacekeepers were scrutinized. The dominant scientific position based on criticizing the assimilationist Indian policy, discriminatory measures against the First Nations and ethnic intolerance is concluded to be justified. And therefore the study is politically and historically relevant: it is important to understand that the discriminatory ethnic policy is often integral to the development of seemingly respectable political regimes, which maintains the effects, sometimes hidden, of such discrimination on modern social (dis)integration.

Authors: Zainiddin N. , Tinibekov М. Kh. , Ilkhamova F. S.
Published: April 2021

Aim of study. Identify the features and offer the best tactics for the surgical treatment of vascular injuries in traumatic shock.

Material and methods. The clinic has 36 patients with hemorrhagic and traumatic shock. Of them: 33 men (91.6%), women 3 (8.3%). We found, among those admitted to the clinic, 36 patients with hemorrhagic and traumatic shock. So, in 5 patients, the condition was extremely serious. The use of angiography and MSCT is of great importance for the early diagnosis of traumatic vascular damage.

Results. We have performed 36 different operations for patients with shock after vascular injury: vessel ligature —  19; lateral suture —  5. Of them: at the same time imposed side seam venous vessels; сircular suture —  4; autovenous shunting —  3; prosthetics —  4: primary amputation —  1 and 7 patients with epineural suture. Along with this, severe shock, massive tissue damage and irreversible ischemia were indications for limb amputation in 1 (2,7%) patients with vascular damage. Arrosive bleeding was observed, only in one patient. In 24 (94,4%) patients, wound healing was primary, in 2 (5,5%) patients, wounds healed by secondary intention.

Conclusions. The high efficiency of timely application of reconstructive- restorative operations —  autovenous shunting and vascular prosthetics after stabilization of hemodynamic parameters depends on the degree of traumatic and hemorrhagic shock.
IMPROVING THE PROVISION OF SURGICAL CARE TO THE CIVILIAN POPULATION WITH GUNSHOT WOUNDS TO THE CHEST IN CONDITIONS OF LOCAL ARMED CONFLICT
Authors: Masljakov V. V. , Chuprina A. Р. , Kurkin К. G.
Published: April 2021

The aim of the study is to improve the organization and provision of surgical care to civilians with gunshot wounds to the chest in the context of armed conflict on the example of the Chechen campaign.

Materials and methods. The work is based on the analysis of medical care provided to 106 wounded with gunshot wounds to the chest from the civilian population in the period from 1991 to 2000. Medical care was provided on the basis of the surgical hospital of the city hospital No. 9 in Grozny.

Results and discussion. Found that providing medical care to wounded with gunshot wounds of the chest when massive flow in terms of actual hostilities rendered by the forces and means of civil hospitals, has a certain specificity. It is due to the fact that in such conditions, in contrast to military medical organizations, there are no stages of evacuation, often the wounded are delivered by non-specialized and unsuitable vehicles on destroyed roads, while they are not given or given insufficient pre-medical care. In such conditions, the workload of medical personnel of civil medical institutions associated with the provision of medical care increases. In this regard, in our opinion, it is necessary to develop measures aimed at improving the algorithm aimed at minimizing various errors that occur in civilian medical institutions during the mass admission of wounded.

Phytochemical Screening, Cytotoxicity and Antioxidant Activities of Leaves Extracts from Eucalyptus citriodora
Authors: Idris Musa Maikudi , Yelwa Adamu Mohammed , Muhammad Aminu
Published: April 2021

The genus Eucalyptus has been used in African traditional medicine for the treatment of cardiovascular diseases and diabetes. In this work, chloroform and methanol extracts from the leaves of Eucalyptus citriodora was investigated for their phytochemicals, cytotoxicity and antioxidant potentials. Phytochemical screening of the extracts showed the presence of alkaloid, flavonoid, phenols, reducing sugar and steroids in the methanol extract. IR absorptions of the extract supported the presence of these phytochemicals by revealing the bands 3335 cm-1 (O-H), 1613, 1480 cm-1 (C=C) and 1721 cm-1 (C=O). Evaluation of the cytotoxicity of the methanol extract using brine shrimp assay, suggested that, the extract was not toxic with LC50 value of 1.64 mg/mL. Antioxidant potentials of both chloroform and methanol extracts were determined using phenolic content quantification and 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging. Methanol extract (37.32 μg TAE/mg) had higher phenolic content than the chloroform extract (12.09 μg TAE/mg). The radical scavenging potentials of the extracts recorded inhibitory activities of IC50 values of 892.7 μg/mL (chloroform extract) and 8.3 μg/mL (methanol extracts) relative to the positive control values of 31.1 μg/mL (butylated hydroxytoluene) and 3.5 μg/mL (ascorbic acid). These results showed that E. citriodora might contain promising antioxidant agents.
“É proibida a igualdade gênero nesse estabelecimento”: discursos sobre a “Lei da Ideologia de Gênero” em Santa Rita, Patos e Campina Grande – Paraíba (2017-2018)
Authors: Arruda Guilherme de Lima , Soares Junior Azemar dos Santos
Published: April 2021

Esse artigo tem por objetivo analisar os discursos dos parlamentares que propuseram a chamada “Lei da Ideologia de Gênero” nos municípios de Santa Rita, Patos e Campina Grande no estado da Paraíba. Essas leis foram propostas e aprovadas a partir do embasamento ideológico cristão, com a finalidade de proibir o debate de gênero nas escolas públicas e privadas dos referidos municípios. Metodologicamente, utilizamos a proposta da análise do discurso a partir de Michel Foucault (2014) que visa perceber a produção discursiva como um exercício de leitura, interpretação e produção de um outro/novo discurso. Para tanto, nos debruçamos sobre as entrevistas feitas com os três parlamentares no sentido de perceber seus interesses e “ideologias” defendidas. Ideologia, gênero e educação são categorias fundamentais para o diálogo teórico nesse texto. Portanto, conclui-se que a chamada “Lei da Ideologia de Gênero” funcionou como um dispositivo proibitivo e punitivo, mas que também gerou resistências.
Educación Sexual Integral y Performatividad: un Abordaje Filosófico Feminista
Authors: Godoy Elsa Daniela
Published: April 2021

A philosophical analysis of J. Butler's performativity in relation to Comprehensive Sexual Education is carried out, which allows us to understand the implicit heterosexist matrix of intelligibility in pedagogies of gender and sexuality. In the context of implementation of Comprehensive Sexual Education in Argentina and based on research on its achievements and challenges, it is argued that this gender perspective contributes to overcoming binary approaches that stigmatize sexual diversity. As an interdisciplinary contribution to the educational field, reflection from performativity enhances changes in curricular content that Queer and feminist movements demand, as well as liberating displacements of the norms in school practices.
The Entomology in Argentina until the creation of the Sociedad Entomológica Argentina. A historical survey
Authors: De Asúa Miguel
Published: April 2021

In this paper, a historical survey of the development of the entomological studies in Argentina from the 18th century to 1925, the year in which the Sociedad Entomológica Argentina was created, is presented. Three periods are distinguished in this historical survey: (a) research on insects in colonial and early independent Río de la Plata, and in early Argentina until the 1870s; (b) the period from c. 1870 to c. 1900, in which entomology functioned as a core around which much of the zoological studies were organized; (c) the period from c. 1910 to c. 1925, which involved the development of large entomological collections in the Argentine Museum of Natural Sciences (Buenos Aires) and the Museum of La Plata, the beginnings of applied entomology with the hiring of French and American specialists, and the incorporation of women in the field.

The presence of rainbow trout reduces drift of aquatic insects in Yungas streams (Tucumán, Argentina)
Authors: Serra Greppi Iris C. , Molineri Carlos
Published: April 2021

The drift or transport of individuals downstream is an important phenomenon of rivers and streams, since most aquatic organisms participate in it at some period of their life cycle. This work describes the assemblage of macroinvertebrate drift from ten sites in eight mountain streams of Tucumán, and evaluates the effect of the presence of rainbow trout (Oncorhynchus mykiss Walbaum), an exotic fish and visual predator, on this fraction of the community. Thirty-one (31) families of drifting aquatic invertebrates were identified, mainly immature insects and to a lesser extent water mites (Acari: Hydrachnidia), oligochaetes (Annelida: Oligochaeta) and nematodes (Nematoda). The richness and diversity of the sites with trout did not differ from the others, except when comparing lower and upper reaches of a same stream. Samples from rivers without trout or with low density of trout did not show significant changes in drift density of macroinvertebrates. In contrast, in rivers with high trout densities, a notable decrease in insect taxa was observed (those with large sized individuals): Baetidae (Ephemeroptera), Gripopterygidae (Plecoptera) and Leptoceridae (Trichoptera). On the contrary, the density of small Diptera, water mites, oligochets and nematodes increased in trout-streams

Sexual dimorphism in flies has been evidenced in classical morphological characters, but little is known about the differentiation in wing geometry, a multivariate character highly controlled at the genetic level that influences the flight and impacts its life history and can be analyzed through geometric morphometrics. Here, we evaluated sexual dimorphism in the wing geometry of Musca domestica L., a cosmopolitan synanthropic fly. Specimens from Colombia were used for wing mounting, photography, and landmark-based geometric morphometric analysis. We found significant differences between male and female specimens in wing size and shape. Particularly, cross-validated classification based on wing shape resulted in high scores (90%) of correct sex attribution. The influence of wing geometry differences on the flight performance and life history in this species remains unknown.
The debtor-attributes information and the probability of performing loans in the microfinance sector
Authors: Raharja Bayu Sindhu
Published: April 2021

Based on the recent evidence of the high rate of non-performing loans in Indonesia’s microfinance sector, there is a need to formulate a mechanism that could control such credit risk. This study attempts to identify the pivotal determinant factorsresponsible for performing loans. In particular, this research proposes demand-side factors, such as debtor-attributes information, as critical for ensuring installment payments. Using unique data from microfinance in Central Java, it employs logistic regression analysis to prove that debtors’ age and type of collateral significantly affect loan performance. This paper further shows that other variables, such as the payment period and the interest rate, also substantially affect credit risk. These findings have empirical and practical significance. For practical purposes, this research develops the new perspective that debtor-specific information, particularly on their behavioral aspects, requires more in-depth review. This insight may be useful for developing new credit-analyzing tools to alleviate severe non-performing loans. Empirically, this research improves the study of antecedent variables that influence performing loans.
The relationship between counterproductive work behavior and emotional intelligence among pest control employees

Published: April 2021

The primary purpose of this research is to study the effect of emotional intelligence (EI) on the counterproductive work behavior (CWB) of employees in the pest control industry in Indonesia. Although the effect of EI on CWB can be analyzed using the Mayer-Salovey-Caruso Emotional Intelligence Test (MSCEIT), this model is not specific to employees; for this reason, EI will be measured via the Wong and Law Emotional Intelligence Scale (WLEIS). Questionnaires were distributed to 585 pest control employees. The data were analyzed using structural equation modeling (SEM). The results indicate that EI has a statistically significant negative relationship with CWB and that the more emotionally intelligent employees are, the less likely they will be to act counterproductively at work. These findings can potentially reduce the level of CWB for organizations and society by enabling companies to assess the EI of workers.

Aims: This study aimed to increase the utilization of biomass-derived from the waste of coconut and peanut shells by making them as briquettes, as an alternative to fuel. The scarcity of petroleum because of its increasingly limited existence encourages all parties to take part in the development and discovery of new alternative energies. This is expected to overcome one of the most important of the many problems facing this country. The method used in this research is to start with a literature study of materials from various sources about the benefits and manufacturing of briquettes from biomass waste as an alternative energy source to be further tested for quality.  This involves a heat test, water content test, ash content test and determination of the flying matter. Results: The test results showed that natural gas emissions were below threshold, namely 0-30 ppm CO, 0-3.6 ppm H2S, and undetectable NOx. After evaluation, the results showed that with the addition of 30% of the biomass, the ignition time was reduced and the remaining unburned briquettes or bottom ash was reduced by 68.68%. Conclusion, significance, and impact of study: The results help the community and the parties involved related to appropriate bio briquettes technology. It also eventually becomes one of the solutions to assist the government in solving problems related to alternative fuels to petroleum.
THE PRESERVATION OF RIVERBANK SETTLEMENT AS A TOURISM POTENTIAL IN THE CITY OF PALEMBANG, SOUTH SUMATERA
Authors: Oktarini Maya Fitri , Johannes Adiyanto , Prima Listen
Published: April 2021

Aim: This study examines the current living culture of riverbank residents by observing the choice of factual house and the house preferences. A house is the physical characteristic of cultural products indicating the current living culture. The riverbank settlements are part of the historical development of the city of Palembang. Methodology and Results: This research focuses on the physical form of residential buildings from the perspective of socio-cultural preservation. Restoring the characteristics of the riverbank area is a necessary potential. The design process can be directed toward technical innovation, social aspect and the use of materials that correspond to the features of the area. Furthermore, the cultural ecological interaction has created a living culture in the riverbank. This is evident in the constructed houses of residents with structure, technology, and material conforming to the fluctuating conditions of the ecosystem. The settlement’s characteristics generate an image of a river city, which have also become a tourist attraction in Palembang. However, the living culture has changed due to the innovation in building technology, the shift in the focus of development, and the availability of natural resources which diminish these features. Conclusion, significance and impact of study: This will encourage tourists to visit the developed areas with a preservation approach, integrating new cultural living with the conservation of the river city features for tourism interest. Furthermore, the preservation of tourism activities are not only unchanged, but also an adaptation flexibility to continuously look for new forms for the symbiosis between man and nature.

Aims: This study aims to determine the synthesis of bagasse to form surfactants and evaluation of the performance of the sample to increase oil yield. Indonesia generates very large amounts of solid waste, without recycling or adequate management efforts to preserve the environment. Bagasse emerged as one of the most abundant biomass due to the operations of large plantations and factories. Furthermore, previous studies showed extensive uses in the fields of compost, animal feed, bioethanol energy, paper, and reinforced building materials. Methodology and Results: Lignin was extracted from bagasse to process sodium lignosulfonate surfactant (SLS surfactant). The synthesis was characterized several times, and certain examples showed significant HLB values, as a function of emulsion builder. This condition in the oil reservoir is required to reduce interface stress (IFT) and friction in the movement of particles. Another analyses involves the assessment of core flooding of specific synthetic core and crude samples. Conclusion, significance and impact of study: The results confirm the ability of surfactant bagasse to increase oil recovery, namely the HLB value of 11.6. The results also show the surfactant classification with the ability to form a middle-phase emulsion in order to increase petroleum products. Therefore, bagasse as solid waste has a performance effect on the process of increasing petroleum production.
