Authors: Saeed Salih Shahad Jamal , Khalil Mahmood Hameed
Published: May 2023

يهدف البحث إلى تحليل وقياس أثر الإنفاق الاستثماري في مستويات الدخل القومي للعراق، وتم استخدام نموذج الانحدار الذاتي لفترات الإبطاء الموزعة (ARDL) لمعرفة أثر العلاقة بين المتغير المستقل (الإنفاق الاستثماري) والمتغير التابع (الدخل القومي) باستخدام اختبار علاقة قصيرة الأجل ((short run coefficients والتكامل المشترك (Bound test) والعلاقة طويل الأجل (long run coefficients)، ومن أجل التحقق من النتائج تم الاعتماد على سلسلة زمنية ممتدة من 2005-2020. وتوصل البحث إلى مجموعة من النتائج أهمها كانت وجود أثر إيجابي للإنفاق الاستثماري على الدخل القومي في الأجل القصير، فضلا عن أن هنالك تأثير إيجابي للإنفاق الاستثماري إذ إن ارتفاع قيمته بمقدار وحدة واحدة يؤدي إلى ارتفاع الدخل القومي (National income) بمقدار 0.045 مليون دينار عراقي بافتراض ثوابت العوامل الأخرى (الإنفاق الاستهلاكي والإنفاق الحكومي والتجارة الخارجية)، كما وتشير النتائج إلى عدم وجود علاقة طويلة الأجل بين الإنفاق الاستثماري والدخل القومي كون الاحتمالية لها أكبر من (5%)، إذ بلغت الاحتمالية لها (0.3200)، أي 32% وهذا ينطبق مع واقع الاقتصاد العراقي حيث إن زيادة الإنفاق الاستثماري لا تؤدي إلى زيادة الدخل القومي كون الإنفاق الاستثماري يحتوي على درجة انحراف كبيرة عن الإنجاز المطلوب، أما أهم المقترحات التي قدمها البحث هي اتباع سياسة مالية تعمل على معالجة الاختلالات الهيكلية في هيكل النفقات العامة تعمل على تخفيض مساهمة الإنفاق الاستهلاكي من الإنفاق العام. واتباع سياسات رقابية من أجل وضع حد للانحراف الحاصل في الإنفاق العام.

For environmental and economic purposes, it is necessary to search for methods that reduce gas emission by flare from the oil refineries. It causes environmental pollution and warmup. All laboratory tests have been completed at Koya University, with the contribution of the Institute of Technology in Koya, to check some readings and verify their accuracy. Increasing the absorptivity of the gases by heavy oil will have expected to improve oil burning characteristics. This research aims to determine the best operating conditions that leads for higher absorption. In this research the diesel oil is considered as a heavy cut and LPG as a light gas. A lab scale unit was installed for that purpose. The amount of changes in oil weight before and after atomizing was determines as well as, the properties of the diesel oil like flash point, cetane number, and diesel index. The effect of a wide range of atomizing time (10, 20, 30, 40, 50, 60, and 90) minutes at different temperatures (0, 10, 20, 30, 40, and 50) °C was considered. The data is discussed and graphically analyzed.  The optimum operating conditions is achieved by, 9 liters/minute gas Atomizing flowrate of LPG for one liter of diesel oil, atomizing Temperature is 30 ᵒC, atomizing Time is 30 minutes’ minimum till 60 minutes’ maximum. The produced Diesel Flash Point is 55 ᵒC, and the amount of gas absorption is 24 gm per 850 gm of diesel oil which represent 2.8 % of diesel weight and 5% of LPG gas flowrate.

Authors: Dias Vicente Mussi , Freire Maria das Graças Machado
Published: May 2023

The preservation of the Restinga biome is of great importance, both ecologically and socially, and this ecosystem is threatened mainly by anthropic actions, with little known about its fungal diversity. Endophytic fungi, besides contributing to the prospecting of new efficient compounds in industry and agriculture, can indicate the richness and abundance of species in the areas where they are found. Thus, the objective of this work was to carry out an inventory of endophytic fungi prospecting from plant species in the Açu, Gargaú, Grussaí, and Jurubatiba restingas, located in the north of Rio de Janeiro State, Brazil. Leaves of 78 plant species were collected, from which 1787 isolates were obtained in culture medium, identified in 36 different genera. After analyzing the data of richness and abundance of the fungi found, the biodiversity of the four restingas was estimated, indicating a high diversity in the ecosystem, being the restinga of Açu the most preserved and the restinga of Gargaú the most degraded when evaluated by Margalef Richness Index.
EVALUATION OF CANDIDA ALBICANS AND ITS ASSOCIATED RISK FACTORS AMONG MARRIED WOMEN OF REPRODUCTIVE AGE IN ZAKHO CITY, KURDI-STAN REGION, IRAQ
Authors: Haydar Shivan Othman , Naqid Ibrahim A
Published: May 2023

Background: Candida vaginitis is a major fungal infection of the female genital tract ranging from mucosal to systemic infection.  Candida species has remained a major public health issue affecting women globally.
Objectives: The aim of this study was to evaluate the prevalence of Candida albicans and its associated risk factors among married women with signs and symptoms of vaginitis referring to Obstetrics and Gynecological Hospital at Zakho City, Iraq.
Methods: Vaginal samples were collected from 150 symptomatic women aged 18-48 years from October 2021-to April 2022 using two sterile cotton swabs. Wet mount was initially performed from first swab for the presence of budding yeast cells, and pseudo-hyphae of Candida infection. The second collected swabs were cultured on Sabouraud dextrose agar and incubated at 35°C for 24-48 hrs. C. albicans was then detected using morphologic characteristics of the colony.  Candida colonies were finally confirmed by germ tube test.
Results: Overall, 58 (38.67%) C. albicans were diagnosed. The highest rate of infection was reported in the age group of 31-40 years (45%) and non-educated people (37%), but statistically not significant (p>0.05). C. albicans was also higher in women who used pills as a contraceptive (45.45%) than other types of contraceptives. Women who had low number of births were significantly associated with C. albicans (OR; 1.01, 95% CI; 0.94-1.26, p=028). C. albicans was also significantly associated among symptomatic patients with vaginal itching (67.19%) (OR; 9.69, 95% CI; 4.52-20.79, p=0.001) and vaginal pH level > 4.5 (OR; 0.39, 95% CI; 0.19-0.82, p=0.001). C. albicans was also significantly higher among participants who had whitish vaginal discharges (96.67%) (OR; 8.0, 95%CI, 3.8-16.85, p=0.001), and yellow-green vaginal discharges (58.62%) (OR; 0.12, 95% CI; 0.01-0.93, p=0.007).
Conclusions: C. albicans is a relatively common gynaecological problem among married women in our region. C. albicans is significantly higher among child bearing age women who had vaginal discharges and itching in our study. These results call for preventive measures to protect women against Candidiasis. Therefore, public health education and campaign should be implemented.

Published: May 2023

While among the most common functional handles present in organic molecules, amines are a widely underutilized linchpin for C–C bond formation. To facilitate C–N bond cleavage, large activating groups are typically used but result in the generation of stoichiometric amounts of organic waste. Herein, we report an atom-economic activation of benzylic primary amines relying on the Sulfur Fluoride Exchange (SuFEx) click chemistry and the aza-Ramberg-Bäcklund reaction. This two-step sequence allows the efficient generation of 1,2-dialkyldiazenes from primary amines via loss of SO2. Excitation of the diazenes with blue light and an Ir photocatalyst affords radical pairs upon expulsion of N2, which can be coaxed into the formation of C(sp3)–C(sp2) bonds upon diffusion and capture by a Ni catalyst. This unique arylative strategy relying on a trace-less click approach was harnessed in a variety of examples and its mechanism was investigated.

Published: May 2023

Actin, a key component of the cytoskeleton in eukaryotic cells, plays a crucial role in regulating cell morphology and transport. The morphology, mechanical, and biochemical properties of these filaments and bundles are determined by their monomer structure and by protein-protein contacts. Crowded environments are known to organize filaments into bundles. However, less is known how crowding and bundling affect the structure of F-actin. Here, we employed two-dimensional infrared (2D IR) spectroscopy and structure-based spectral calculations to investigate the morphology-dependent secondary-structure and local environments in filaments and weakly or strongly bundled networks. The results indicate that actin undergo secondary structural changes upon bundling, resulting in a decrease in beta-sheet and increase in the loop conformations. Moreover, strongly bundled networks experience a decrease in backbone solvent exposure, with relatively low perturbation of alpha-helix and the beta-sheet nearly ``locked" in buried positions. Similar changes are observed in the loops, which become less hydrated but exhibit a dynamic environment. In summary, our study provides insights into the structure and structure-dependent local environment of actin biopolymers under morphology control by PEG, emphasizing the significance of loop structure as a critical player in actin network morphology and stability.
Using Neural Network Potentials to efficiently calculate indirect free energy estimates
Authors: Tkaczyk Sara , Karwounopoulos Johannes , Schöller Andreas , Woodcock H. Lee , Langer Thierry , Boresch Stefan , Wieder Marcus
Published: May 2023

To achieve chemical accuracy in free energy calculations, it is necessary to accurately describe the system's potential energy surface and efficiently sample configurations from its Boltzmann distribution. While neural network potentials (NNPs) have shown significantly higher accuracy than classical molecular mechanics (MM) force fields, they have limited range of applicability and are significantly slower than MM potentials, often by orders of magnitude. To address this challenge, Rufa et al suggested a two-stage approach that uses a fast and established MM alchemical energy protocol, followed by reweighting the results using NNPs, known as endstate correction or indirect free energy calculation. In this study, we systematically investigate the accuracy, robustness, and efficiency of free energy calculations between a MM reference and a neural network target potential (ANI-2x) using free energy perturbation (FEP) and non-equilibrium (NEQ) switching simulation in vacuum. We investigate the influence of longer switching lengths and the impact of slow degrees of freedom on outliers in the work distribution. We compare the results to multistage equilibrium free energy calculations (MFES) for an established dataset. Our results demonstrate that free energy calculations between NNPs and MM potentials should not be performed using FEP but require NEQ switching simulations to obtain accurate free energy estimates. NEQ switching simulations between MM and NNPs are highly efficient, robust, and trivial to implement.
Simple lattice model explains equilibrium separation phenomena in glassy polymers
Authors: Yuan Tianmu , De Angelis Maria Grazia , Sarkisov Lev
Published: May 2023

The Robeson bound is a theoretical limit that applies to kinetics-driven membrane separations of gas mixtures. However, this bound does not apply to sorption-driven membrane processes such as CO$_\text{2}$/N$_\text{2}$ separation, which lacks a theoretical explanation. As a result, we are uncertain about the factors that control the limiting behavior of sorption-driven separations. To address this issue, we employed a simple lattice model and dynamic mean field theory to examine the transport properties of disordered model structures, isolating sorption effects from purely kinetic effects. Our findings indicate that transport effects play a crucial role in sorption-driven processes, and perm-selectivity is consistently lower than sorption selectivity, which is an unattainable limit. We used basic geometric fragments of the structure to explain how transport effects emerge and manifest themselves in sorption-driven processes.

Published: May 2023

Multiscale techniques should allow for the integration of detailed atomistic information on materials and reactions to predict the catalytic performance of full-scale reactors. Although many attempts have been presented in the literature, difficulties still appear. These challenges are grouped into two main groups: catalytic complexity and differences between time and length scales of chemical and transport phenomena. Here, we introduce AMUSE (Automated Multiscale Universal Simulation Environment), which allows for building a seamless Multiscale modeling workflow. Starting from Density Functional Theory (DFT) data and automated analysis of the reaction networks through graph theory, microkinetic modeling is integrated into a standard open-source Computational Fluid Dynamics (CFD) code. We present technologically relevant case studies to demonstrate the capabilities of AMUSE by applying it to the CO2 hydrogenation on In2O3-based catalysts and isopropanol dehydrogenation on two Co facets.
Investigation of the impact of unsteady air flows on the mechanical and operational properties of aircraft structural elements
Authors: Ivanov D. A.
Published: May 2023

The use of pulsating subsonic gas flow treatment (gas pulse treatment) in the process of maintenance and repair for a duration not exceeding a certain value contributes to the restoration and improvement of mechanical and operational properties of aeronautical equipment structural elements. This article presents the results of a study to determine the optimal duration of gaspulse processing of aircraft parts, as which, the duration of processing was adopted, providing the maximum increase in the properties of material viscosity, which prevents crack development without reducing the strength properties. As a result of the study, the influence of various factors, such as the subsonic airflow velocity and the frequency of oscillations, the material and geometric parameters of the processed product, on both the optimal and leading to a decrease in mechanical properties duration of processing by pulsating airflow of aircraft structural elements during maintenance and repair, was evaluated. It has been established that mechanical waves generated by gas flow pulsations can have a significant impact on the structural strength of aircraft structural elements, which makes it possible to increase their reliability as well as the accuracy of forecasting the technical condition. The harmonic nature of the attenuation of the ratio of residual stresses to their initial values has been experimentally established, depending on the duration of gas pulse treatment, which allows us to control their magnitude and sign. An empirical formula has been obtained to determine the optimal processing time for products of various materials. As an indicator of the duration of gas pulse treatment, an increase in the viscosity of the material was adopted without reducing the strength properties. Graphical dependences of the relative time of gas pulse processing, which provides an increase in the mechanical properties of the relative frequency of the gas flow oscillations, have been constructed.

Published: May 2023

The formulation of the flight safety history problem is stated. The article shows that it is problematic to scientifically substantiate, systematize, analyze and generalize the theoretical and empirical flight safety material accumulated in various fields. From a historical perspective, the necessity for a socio-humanitarian assessment of the transformation processes of scientific and applied experience in the field of flight safety is substantiated. New multidisciplinary line of research, making use of a specific scientific apparatus and methodological tools, i.e., the history of flight safety, the subject basis of which covers social activities throughout the life cycle of all aerospace engineering (artificial flying objects in the Earth's atmosphere and space, aircraft, crews, passengers, other aerospace system specialists), including aeronautics, aviation, cosmonautics over a span of the entire history of mankind, is proposed. A brief overview of publications on the issue of flight safety is offered. The experience of flight safety history research is analyzed. The periodization of flight safety history in the XX–XXI centuries, giving prominence to three stages: 1. Generating ideas, technologies, flight safety systems (10–40s of the XX century). 2. Establishing the national and international systems to ensure flight safety, scientific research, personnel education and training in the field of flight safety (50–80s of the XX century). 3. Developing new ideas, technologies, projects, flight safety management systems, active ensuring of flight safety, etc. (since the 90s of the XX century), is proposed. The foundations of the conceptual model of the flight safety history are presented, the methodology, experience and prospects of research are considered. It is recommended to organize systematic studies of the flight safety history, covering the aspects of the world and domestic science, education and practice; to create a unified information system on the history of flight safety based on new information technologies, the ultimate aim of which can be a virtual worldwide museum of flight safety; to initiate a pilot project of the National Flight Safety Museum of Russia and to start its development in the year of the 100th anniversary of our civil aviation; in the future, to develop a new academic discipline "History of Flight Safety" for training aerospace industry specialists and researchers.

Authors: Selin A. I. , Turkin I. K.
Published: May 2023

Currently, the big number of companies, and specifically in Russia, is engaged in designing unmanned aerial vehicles (UAV). It is caused by the tendency to reduce human labor in various fields of activity, in particular, associated with a great risk to life and health. All these factors lead to the steady growth of different-type missions for the UAV application. Urgency of the research generates considerable interest towards the issues of the UAV application. As part of developing a method for determining UAV design parameters, the author analyzed the results in this domain, considering the operation in a group of aircraft. In order to propose a conceptual aircraft solution for designing a model, the analysis of target objects for the UAV group application was conducted. The article considers various target objects for the application of UAV groups. The result of the analysis for target objects can form the basis for the conclusion involved with the imposed requirements for the design of this UAV class. Compared to other specialists’ articles, this paper is distinguished by synthesizing the achievements in the sphere of group-operated UAV design, as well as by establishing the basic trends for their application while conducting warfare.
Investigating Anxiety in Speaking among EFL Students: A Qualitative Study
Authors: Khafidhoh Khafidhoh , Wijayati Rifky Dora , Risa Sarah Hizza
Published: May 2023

This study investigates the causes of anxiety in speaking among EFL students and provides solutions to overcome them. A total of 33 students from the sixth semester of the English Education Department at Universitas Ahmad Dahlan participated in this descriptive qualitative research by completing questionnaires and interviews. The results revealed that nervousness, trembling, and shyness are causing anxiety among students in speaking English, and preparation, confidence, peer-seeking, and effort can help overcome speaking anxiety. The implication of the study suggests that language educators should be aware of the causes of anxiety in EFL students and provide appropriate solutions to help them overcome their speaking anxiety. Limitations of the study may include the relatively small sample size and the fact that the study only focused on sixth-semester students in one particular department at a single university. Therefore, the findings may not be generalizable to other populations or contexts. For future research, it would be useful to include a more extensive and diverse sample of participants from different levels of language proficiency and different educational backgrounds. Additionally, incorporating other data collection methods, such as observation or focus groups, could provide a more comprehensive understanding of the factors contributing to speaking anxiety among EFL students. Finally, exploring the effectiveness of different interventions or strategies to reduce speaking anxiety could be an interesting avenue for future research.

Multi-step CNN forecasting for COVID-19 multivariate time-series
Authors: Haviluddin Haviluddin , Alfred Rayner
Published: May 2023

The new coronavirus (COVID-19) has spread to over 200 countries, with over 36 million confirmed cases as of October 10, 2020. As a result, numerous machine learning models capable of forecasting the epidemic worldwide have been produced. This paper reviews and summarizes the most relevant machine learning forecasting models for COVID-19. The dataset is derived from the world health organization (WHO) COVID-19 dashboard, and it contains official daily counts of COVID-19 cases, fatalities, and vaccination use reported by countries, territories, and regions. We propose various convolutional neural network (CNN) based models such as CNN, single exponential smoothing CNN (S-CNN), moving average CNN (MA-CNN), smoothed moving average CNN (SMA-CNN), and moving average smoothed CNN (MAS-CNN). Here, MAPE and MSE are used to assess the suggested models. MAPE is frequently used to compare accuracy across time series with different scales. MSE, the model must strive for a total forecast equal to the entire demand. That is, optimizing MSE seeks to create a forecast that is right on average and so unbiased. The final result shows that SMA-CNN outperformed its baselines in both MAPE and MSE. The main contribution of this novel forecasting approach is a more accurate result as a base of the strategy of preventing COVID-19 spreads.

PIRANTI EMOTIF DAN TRANSPOSISI MAKNA DALAM WANGSALAN
Authors: Wijoyanto Danang
Published: May 2023

Abstrak

Wangsalan adalah salah satu gaya bahasa dalam bahasa Jawa yang unik dan rumit. Keunikan tersebut dapat dilihat pada struktur dan cara pemroduksiannya. Struktur wangsalan terdiri atas sampiran dan isi. Sampiran wangsalan berwujud cangkriman. Isi wangsalan sendiri berupa pesan yang ingin disampaikan oleh penutur. Antara teka-teki dan isi wangsalan tidak mempunyai hubungan makna melainkan hanya hubungan bentuk. Hubungan bentuk tersebut terletak pada jawaban teka-teki dengan maksud wangsalan. Pemroduksian wangsalan rumit karena di dalamnya terdapat fenomena transposisi makna. Transposisi makna dalam wangsalan terjadi pada makna denotatif dengan makna asosiatif. Transposisi makna adalah upaya untuk menghubungkan perbedaan bentuk lingual dengan maksud penutur. Akibatnya keberpisahan dan ketaksinambungan bentuk dapat bertemu. Maka dari itu alat penghubung untuk mempertemukan perbedaan itu adalah piranti emotif. Piranti emotif tersebut sebagai penghubung antara teka-teki dengan maksud dan isi wangsalan. Piranti emotif tersebut ada tiga yaitu fonetik, leksikal dan sintaksis. Ketiga piranti tersebut dapat dijadikan prinsip untuk memproduksi wangsalan. Berdasarkan pembahasan tersebut sumbangan terhadap pembelajaran tentang materi wangsalan adalah bahwa wangsalan tidak hanya ditalikan oleh bunyi saja namun juga kata. Wangsalan bukan termasuk metafora karena antara batangan dengan isi wangsalan tidak mempunyai hubungan makna dengan ciri-ciri yang dimaksudkan. Hubungan tersebut sebatas pertalian bentuk dan makna layaknya pantun atau parikan.

Developing Early Graders' Collaborative Skills through Group-Work, Play-Based Pedagogy
Authors: Ekeh Martin Chukwudi
Published: May 2023

This study aimed to develop early grade learners' collaborative skills through group work and play-based pedagogy because collaboration is among the twenty-first century's core skills needed among learners. Thus, its development among early-grade learners is paramount, if they are going to fit seamlessly into the twenty-first century. Participatory-action research, as a research design and professional development workshop, guided this study. Three public primary schools (n = 3) and nine teachers (n = 9), who were purposely sampled, constituted the sample for the study. The study was conducted in the Owerri Education Zone, and the data were captured by using semi-structured interviews and learners' performance-rating scales. Respondent validity was employed through member checking to ensure the validity and reliability of the research instrument. Thematic data analysis was used to determine the results and the indings of the study. It was discovered that teachers' knowledge of group work play-based pedagogy was inadequate, thus hampering the development of collaboration skills among early-grade learners. Professional development workshops were mounted to solve the problem through teachers' capacity to use group play-based pedagogy to develop collaborative skills. Among the proffered recommendations was continuous in-service teachers' professional development of current collaborative pedagogical practices that encourage the active participation of early-grade learners.

Authors: Vu Khuu Thuan , Viet Nga Nguyen Thi
Published: May 2023

Feedback is an integral part of students’ learning-outcome (LO) assessment. To ensure that students understand what they did well and what needs improvement, teachers must give them clear and detailed feedback on their accomplishments and shortcomings. Therefore, in teacher training, it is essential to help Future Teachers (FTs) have the skill of providing and using feedback (feedback skills) in LO assessment (besides skills in teaching, building assessment tools, organizing learning activities, scientific research, ...). This study aims to identify the factors that affect feedback skills in LO assessment of FTs, thereby providing measures to develop this skill in FTs. This study uses a quantitative research method and a questionnaire design as a data collection tool. Simultaneously, the study uses the impact method to assess the FTs’ changes in the performance of skills before, during, and after the training process. The results show that the main factors affecting the development of FTs’ feedback skills are: classroom experience; feedback culture; pedagogical training; mentorship; confidence. While there are four types of feedback: Feedback about the task; the processing of the task; self-regulation; self as a person. When testing the impact on developing FTs’ feedback skills, the results also show the effectiveness of the feedback skills training process based on experiential learning. The process consists of 4 stages: Concrete experience, reflective observation, abstract conceptualization, active experimentation. This study has theoretical and practical implications for educators of pedagogical universities in training feedback skills in LO assessment for teachers and FTs.
Effectiveness of Teacher and Peer Feedback in EFL Writing: A Case of High School Students
Authors: Gonzalez-Torres Paul , Sarango Cristhian
Published: May 2023

The aim of this study is to assess and compare the effectiveness of three types of EFL writing feedback: teacher direct, teacher indirect, and peer feedback, while also exploring student perceptions of the feedback they receive. For this purpose, a mixed-method approach was used, combining a quasi-experimental and a survey design. Eighty-two EFL learners (aged 17-18 years old) were divided into four groups (three intervention groups who received feedback and one control group who did not) and practised EFL writing skills for a two-month period. After the intervention, the students from the intervention groups (62) answered a questionnaire related to their perceptions about the feedback received. The results of pre- and post-tests showed an improvement in EFL writing skills in all the groups. Likewise, there was a statistically significant difference in the results of the post-test between the groups who received feedback and those who did not, which means that feedback was effective. However, when comparing the three types of feedback, there were no statistically significant differences among the intervention groups. As for the perceptions of the feedback received during their EFL writing practice, students believed that feedback was a positive aspect of writing instruction. They thought that feedback was important for their learning, and they would like to receive a combination of teacher and peer feedback. This study contributes to the ongoing discussion around the effectiveness of different types of feedback on EFL writing skills.

The demands of research in graduate school make it imperative to assess the readiness of graduate students to conduct research, whether as a requirement for their subjects, or the type of thesis or dissertation. In this study quantitative and qualitative methods were employed, namely a survey questionnaire, interviews, and document analysis, to examine graduate students' readiness in thesis writing and the difficulties they face. The findings reveal that students often struggle with research and statistical tools in the comprehensive exam. Additionally, the students' ability to articulate their knowledge and ideas significantly affects their exam results. Study findings also indicate that students are only moderately prepared regarding research readiness, scoring lowest in identifying research problems and writing literature reviews. As a result, some students abandon their research projects or cannot complete them on time. The data from the interviews further support the quantitative results, indicating that the students lack research skills and face multiple workloads, which impact their ability to complete their research. To address these challenges, the Graduate School in their research programme should offer seminars on developing research skills for students every semester.

Authors: Lestari Devi Agus , Harianto Sugeng
Published: May 2023

Artikel ini berawal dari adanya wisata pemancingan yang popular dikalangan masyarakat Sidoarjo, Surabaya dan sekitarnya. Kampung iwak dan pusat wisata pemancingan Desa Kalanganyar banyak diperbincangkan hingga dimuat pada berita media online. Seorang pengelola mendirikan bisnis pertambakan dengan sistem sewa lepas dari pemilik lahan dikawasan wisata pemancingan. Kekuasaan muncul dari wacana yang dibangun oleh pengelola dan diwujudkan dalam bentuk aturan tertulis dan non tertulis. Penelitian ini hadir untuk mengungkap fenomena relasi kuasa antara pengelola tambak dan pekerja di lokasi tersebut. Tujuan penelitian diantaranya: (1) mendeskripsikan kondisi objektif sosial ekonomi pengelola dan pekerja, (2) menganalisis bentuk relasi kuasa pengelola terhadap pekerja dan (3) menganalisis sikap pekerja terhadap kuasa pengelola. Penelitian ini menggunakan metode kualitatif dengan teknik pengumpulan data observasi dan wawancara mendalam. Perspektif teori post modern Michel Foucault digunakan sebagai pisau analisis dalam mengkaji fenomena di lapangan. Hasil penelitian menjabarkan kondisi objektif sosial dan ekonomi dari subjek bahwa bidang pertambakan adalah pekerjaan utama sebagai sumber kehidupan. Sebagian besar dari mereka memahami ilmu pengetahuan tentang tambak secara turun-temurun dari keluarga. Namun mereka juga memiliki penghasilan tambahan dari pekerjaan sampingan untuk memenuhi kebutuhan sehari-hari dan tabungan jangka panjang. Penelitian ini menemukan bentuk pendisiplinan yang berguna untuk kemajuan bisnis wisata pemancingan. Pengelola membuat sanksi yang ditujukan kepada seluruh pelanggar aturan baik itu pekerja atau pengunjung. Panopticon dilakukan melalui CCTV dan peran pengelola secara langsung dalam mengawasi segala aktivitas di lokasi Joyo Samudro. Hal ini memunculkan perlawanan dan kontravensi bagi pekerja dalam menyikapi keadaan tersebut.
