Authors: Hight Craig , Khoo Elaine , Cowie Bronwen , Torrens Rob
Published: July 2024

This paper reports on the findings from a two-year funded research project exploring software literacy - how it is understood, developed and applied in tertiary teaching-learning contexts and how this understanding serves new learning. MS PowerPoint was selected as an initial focus as it is widely available and commonly used. Two disciplines (Media Studies and Engineering) were case studied and data collection obtained through student interviews and an online survey. Findings revealed that students tend to draw from informal learning strategies when learning to use PowerPoint, they have the functional skills and understanding of the software, and were able to identify some of its key affordances and constraints. However, they were only able to critique these at a superficial level, suggesting a need for formal recognition of software literacy as a means to empower students to engage with software and its use at a more critical level.
Applying Web-conferencing in a Beginners' Chinese Class
Authors: Guo Sijia
Published: July 2024

The development of new technologies and the falling cost of high-speed Internet access have made it easier for institutes and language teachers to opt for different ways to communicate with students at a distance. The emergence of videoconferencing applications, which integrate text, chat, audio/ video and graphic facilities, offers great opportunities for language learning to through the multimodal environment. This paper reports on initial data elicited from a pilot study of using web-conferencing in the teaching of a first year Chinese class in order to promote learners' collaborative learning. Firstly, a comparison of three conferencing tools was conducted to determine the pedagogical value of the web-conferencing tool-Blackboard Collaborate. Secondly, the evaluation of 10 campus-based Chinese learners who conducted three one-hour online sessions via the multimodal environment reveals the users' choice of modes and their learning preference.
A new era
Authors: Evans Richard , Matthew Anne
Published: July 2024

As we race towards a new era, rapid change of conventional models has become the norm. Just as technology has etched itself to the core of society, the sheer quantity of student devices connecting to university networks presents a sector wide challenge coinciding almost perfectly with many universities creating technology rich learning spaces. New fears include future proofing. It is not just a matter of technology becoming outdated. In seeking to accommodate the teaching styles and experience of staff across diverse faculties, is this technology simply too vanilla to meet their needs as they become increasingly skilled and inspired by technology's potential? Through the early findings of a study into staff use of technology within Queensland University of Technology's next generation collaborative learning spaces, this paper explores whether the answers lie in a model presented by students equipping themselves with the tools they need to learn in the 21st century.
Flexibility and function
Authors: Dinmore Stuart
Published: July 2024

This paper discusses the evolution of pedagogies used in technology enhanced learning spaces and their intersection with the principles of Universal Design for Learning (UDL). It also argues that as the next generation of computer integrated classrooms are built we must not forget to design for inclusion. UDL provides a framework for developing course content that can be effective for all students including those from various equity students in a technology rich environment. This paper discusses these factors and outlines some elements of a pilot project at the University of South Australia as it completes construction of a new seven-storey learning centre - the Jeffrey Smart building. The paper in part explores the linkages between the flipped classroom model and UDL and argues for the principles of universal design as a solution to the current pressures within higher education to teach effectively in technology rich environments and the need to be inclusive.

Conflict resolution and forgiveness in the child's psychological well- being; Experimenting with Forgive Freely animated film
Authors: Blessing Adjeketa
Published: July 2024

Over the years, animated films have always captured the interest of people, especially, young ones, irrespective of ethnicity, or religion. Like many other media, animated films have themes that are capable of posing positive or negative effects on their consumers. They are a common commodity in many households around the world. Hardly any household exists who would deny having seen one. However, its role in conflict resolution, forgiveness, and the child’s psychological wellness is under-researched, especially in Nigeria. Using Alfred Adler’s individual psychology theory developed by Rudolf Dreikurs, This study examined the conflict resolution methods children and parents employed in resolving conflict among children. 107 households comprising 221 children were exposed to lesson 11, Forgive Freely of the Become Jehovah’s Friend Animated Film series for 30 days. After this, resolved conflicts and for- giveness were examined concerning the child’s psychological well-being. For a better understanding of the context, the synopsis of lesson 11, Forgive Freely was presented and briefly analysed. Responds to each of the questions used were presented in analytical tables. The descriptive method of data analy- sis was used to analyse the data collected. Percentages and frequencies were used to evaluate the responses collected from the respondents. The conclusion was drawn based on the percentage ratio. The study finds that conflicts arise among children every day but the relationship between animated films (Forgive Freely), conflict resolution, and forgiveness is insignificant. However, there is a significant relationship between resolved conflict, forgiveness, and psychological well-being. Parental intervention in child conflict is emphasised over that of the animated film genre.

Published: July 2024

Urban water management remains a crucial concern for city managers and planners. As water demand forecasting plays a key role in urban water management, identifying factors influencing water demand is particularly important to mitigate water shortage crises. This study utilizes a Markov chain model and Artificial Neural Networks (ANNs) to estimate short-term urban water demand in Tehran. The variables considered for estimation include maximum temperature, water consumption, and precipitation rate in the previous four days. These variables are used as previous events to predict water consumption on the fifth day. Daily data from March 21, 2018 to March 19, 2021 were collected for analysis. The results of the study indicate that the Markov model's forecasting is more accurate compared to the ANN model. The Markov chain model demonstrated 48% and 65% improvement in accuracy compared to the ANN model for the test data and the training data, respectively. This suggests that a Markov chain model can be a valuable tool for estimating short-term urban water demand. The findings of this study can contribute to better urban water management and planning to address water shortage issues effectively.

Published: July 2024

The cobalt electrodeposition from a leaching containing cathode-powdery of spent laptop lithium-ion batteries (LIBs) of different commercial brands, collected from local laptop repair shops, was investigated. Citric acid (0.14 M) and hydrazine (0.1 M) were employed as complexing and reducing agents in the leaching during 24 h. Cobalt, manganese and nickel concentrations in the leachate, obtained by the flame method in an atomic absorption spectrometer, are reported. A rotating cylindrical electrode reactor which consists of a rotating open bottom as cathode and a static outer cylindrical as anode was employed. The numerical flow patterns and cathode velocities that induce the presence of Taylor vortices inside and/or outside the cathode were investigated. RANS equations with the standard k−ε turbulence model and enhanced wall treatment was used. Electrical power measurements were performed to validate simulations. Cyclic voltammetry experiments with synthetic solutions were applied to determine the reduction potential of cobalt (found in −1.2 V vs SCE). Subsequently, electrolysis experiments were carried out at predetermined cathode speeds (50, 75, and 125 rpm), imposing a working cathodic potential of −1.2 V versus SCE during 12 h. Experimental results indicate that the best cobalt recovery rates and current efficiency coincide with the presence of Taylor vortices both inside and outside the cathode, i.e., at 50 rpm. The peak performance in cobalt recovery and current efficiency was recorded at 49 % and 47.3 %, respectively. Finally, the deposits obtained from each electrolysis test were removed from the cathode and analyzed via energy dispersive spectroscopy. The range of purity of Co obtained in the electrodeposit film were between 56.75 % and 74.8 %.
Quantifying the quality of configurational causal models
Authors: Baumgartner Michael , Falk Christoph
Published: July 2024

There is a growing number of studies benchmarking the performance of configurational comparative methods (CCMs) of causal data analysis. A core benchmark criterion used in these studies is a dichotomous (i.e., non-quantitative) correctness criterion, which measures whether all causal claims entailed by a model are true of the data-generating causal structure or not. To date, Arel-Bundock [The double bind of Qualitative Comparative Analysis] is the only one who has proposed a measure quantifying correctness. That measure, however, as this study argues, is problematic because it tends to overcount errors in models. Moreover, we show that all available correctness measures are unsuited to assess relations of indirect causation. We therefore introduce a new correctness measure that adequately quantifies errors and does justice to indirect causation. We also offer a new completeness measure quantifying the informativeness of CCM models. Together, these new measures broaden and sharpen the resources for CCM benchmarking.
Employment management system for universities based on improved decision tree
Authors: Li Jing , Ma Yongsheng
Published: July 2024

With the popularization of higher education, the number of students in colleges and universities is increasing, and how to timely cope with the various problems faced by students in employment has become a major problem faced by teachers in colleges and universities. Due to the low utilization rate of student information by the traditional employment management of college graduates, the quality of employment guidance services is not high. Therefore, to solve this problem, this study proposes a simplified, improved Iterative Dichotomizer 3 (ID3) based on the correlation coefficient, and the algorithm improves the information gain function and simplifies the information entropy formula. The experimental results show that the simplified modified ID3 based on correlation coefficients converges faster than the other two algorithms, starting to converge after only 17 iterations; the loss value is also smaller than the other algorithms, at around 0.12. Its minimum accuracy, precision, recall, and F1-measure for employment status prediction were 86.4, 76.8, 72.8, and 0.82%, respectively, all higher than the rest of the algorithms. The time complexity at a sample size of 80 is only 32 ms, which is lower than the rest of the algorithms. It can be seen that the simplified and improved ID3 based on correlation coefficients can accurately and efficiently perform predictive analysis of graduates’ employment status. The university employment management system proposed in the study has achieved efficient deep utilization of graduate information through ID3, providing assistance to university employment decision-makers and reference for employment guidance for university graduates.
Religiosität und Delinquenz unter christlichen und muslimischen Jugendlichen
Authors: Steinmann Jan-Philip
Published: July 2024

Der Beitrag untersucht den Zusammenhang zwischen Religiosität und Jugenddelinquenz für christliche und muslimische Jugendliche und hinterfragt die Annahme einer negativen linearen Verknüpfung beider Konstrukte aus früherer Forschung. Stattdessen wird vermutet, dass eine delinquenzreduzierende Wirkung von Religiosität nur bis zu einem gewissen Grad an Religiosität vorhanden ist und sich anschließend in eine delinquenzsteigernde Wirkung verkehren sollte, sodass insgesamt von einer u-förmigen Beziehung zwischen Religiosität und Jugenddelinquenz auszugehen ist. Zur Untermauerung dieser Vermutung werden theoretische Perspektiven vorgestellt, die einerseits eine delinquenzreduzierende (soziale Kontrolle, Lernprozesse, Umgang mit Belastungen) und andererseits eine delinquenzsteigernde Wirkung von Religiosität (Fundamentalismus, wahrgenommene Benachteiligung) plausibilisieren. Basierend auf einer Befragung von Jugendlichen der neunten Jahrgangsstufe an niedersächsischen Schulen aus dem Jahr 2022 wird das Vorliegen einer u-förmigen Beziehung zwischen Religiosität und Jugenddelinquenz überprüft. Empirisch zeigt sich, dass zwischen Religiosität und Gewaltdelikten eine kurvilineare, zwischen Religiosität und Eigentumsdelikten jedoch eine lineare Verknüpfung besteht. Diese Befunde gelten sowohl für christliche als auch muslimische Jugendliche. Abschließend werden die Verallgemeinerbarkeit der Ergebnisse sowie die Limitationen des Beitrags diskutiert.

Academic tutoring and the assumptions of education 4.0. Towards a personalised approach and building a learning culture at the university
Authors:   Uniwersytet Ekonomiczny w Poznaniu, Wach Anna , Furmańczyk Joanna ,   Uniwersytet Ekonomiczny w Poznaniu
Published: July 2024

Given the rapid and unpredictable changes taking place in all areas of human activity, there is a need to rethink the role of education in such a dynamic environment, and searching for answers to the question of what kind of competence and skills are needed by students and university alumni is of high importance. It is crucial to consider what and how to teach in order to meet the requirements of the 4.0 economy. An answer to the challenges of education 4.0 would appear to be an individualised approach based on an authentic relationship between the teacher and the learner. The authors of this paper present tutoring as a method of personalised education, based on relationships, as a response to the needs of contemporary education. This paper consists of a theoretical part in which the authors discuss the origins and assumptions of tutoring, placing them in the context of education 4.0, and a research part, in the form of a thematic analysis of statements given during focus group interviews, the aim of which was to identify changes that occur in relation to teachers, students and at the organisational level after the implementation of tutoring in the Poznań University of Economics and Business. The results obtained during the analysis not only enrich the theoretical aspect of education 4.0, but also have practical value, as they show educational solutions whose application strengthens the creation of an environment in which future competences and the learning culture are developed through tutoring.
Multiunit Frontal Eye Field Activity Codes the Visuomotor Transformation, But Not Gaze Prediction or Retrospective Target Memory, in a Delayed Saccade Task
Authors: Seo Serah , Bharmauria Vishal , Schütz Adrian , Yan Xiaogang , Wang Hongying , Crawford J. Douglas
Published: July 2024

Single-unit (SU) activity—action potentials isolated from one neuron—has traditionally been employed to relate neuronal activity to behavior. However, recent investigations have shown that multiunit (MU) activity—ensemble neural activity recorded within the vicinity of one microelectrode—may also contain accurate estimations of task-related neural population dynamics. Here, using an established model-fitting approach, we compared the spatial codes of SU response fields with corresponding MU response fields recorded from the frontal eye fields (FEFs) in head-unrestrained monkeys (Macaca mulatta) during a memory-guided saccade task. Overall, both SU and MU populations showed a simple visuomotor transformation: the visual response coded target-in-eye coordinates, transitioning progressively during the delay toward a future gaze-in-eye code in the saccade motor response. However, the SU population showed additional secondary codes, including a predictive gaze code in the visual response and retention of a target code in the motor response. Further, when SUs were separated into regular/fast spiking neurons, these cell types showed different spatial code progressions during the late delay period, only converging toward gaze coding during the final saccade motor response. Finally, reconstructing MU populations (by summing SU data within the same sites) failed to replicate either the SU or MU pattern. These results confirm the theoretical and practical potential of MU activity recordings as a biomarker for fundamental sensorimotor transformations (e.g., target-to-gaze coding in the oculomotor system), while also highlighting the importance of SU activity for coding more subtle (e.g., predictive/memory) aspects of sensorimotor behavior.
RESEARCH STRATEGIES OF EXILED NARODNIKS IN THE SIBERIAN ETHNOGRAPHY IN THE SECOND HALF OF 19TH – EARLY 20TH CENTURY
Authors: Ледовских А.Ю. , Кебак Т.А.
Published: July 2024

В статье рассматриваются исследовательские стратегии ссыльных народников, занимавшихся этнографическими проблемами в Сибири во второй половине XIX – начале XX в. На основе мемуарных текстов, переписки и материалов научных работ «невольных поселенцев» охарактеризована специфика постановки ими научных целей и задач. Особое внимание обращено на раскрытие мотивации, вовлекавшей ссыльных народников в изучение населения восточного региона, их теоретической и практической подготовки к научным исследованиям. Кроме того, затрагиваются особенности организации экспедиций с учетом ограниченности прав политических ссыльных, сложностей во взаимодействии с представителями имперской администрации на разных ее уровнях, освещаются трудности с публикацией народниками результатов своих научных исследований.

Ethnographic research in the Russian Empire experienced its heyday in the second half of the 19th century and the beginning of the 20th century, and multiple ethnographers emerged from among the exiled Narodniks during this rise. Their research activities attract special attention because of the contrast between their lack of specialized, and more often even complete higher education, and the successes in science that they managed to achieve. In recent years, the study of the experience of exiled Narodniks as ethnographers has intensified in the fields of intellectual history and the history of ethnography, but their research strategies have not yet become the subjects of special study. Turning to the texts of the memoirs of ethnographers-Narodniks and other political exiles, as well as their articles in specialized magazines and published correspondence, the present article tries to answer the question of how they solved their research tasks without the appropriate basic theoretical and practical training. Considering that the Narodniks were not professional researchers and were spontaneously involved in the study of the indigenous population, special attention is paid to their research motivation, which was not limited to the need to conduct at least some kind of intellectual activity in the conditions of the exile. The success of the “involuntary ethnographers” has led to the attention to the resources they had at the beginning of their research, including full everyday involvement in the life of Siberian indigenous people and knowledge of at least one local language. The authors focused on the transition from “spontaneous” to organized ethnographic research, the difficulties that arose at the stage of organizing the expeditions and the nuances associated with the processing and publication of the gathered materials.

Authors: Daniel Esther S , Ann L Kathy , Ramdeen M Gloria , TG Sowbhagyarathna , Balamurugan G , Vijayarani M , M Stanley , D Revathy , S Suman
Published: July 2024

Background & aim: The attitude of nursing students towards the care of dying patients is a crucial aspect of their education and professional development. This attitude can significantly impact the quality of care provided to patients at the end of life. Inclusion of palliative care and end-of-life care in the nursing curriculum positively influences students' attitudes. The aim of this study was to examine nursing students’ attitudes towards care of dying patients before and after a course in palliative care. Methods: This study was an evaluative, quantitative, cross-sectional study in which participants (n=102) were selected via random sampling. The Frommelt Attitude Toward Care of Dying Scale (FATCOD) was used to assess nursing students’ attitudes during their education. Nursing students enrolled in a mandatory palliative course in the nursing programme at Rajiv Gandhi University of Health University (RGUHS) were the samples. Ethics approval was obtained from Institution Review Board. Data from FATCOD was analyzed using descriptive and analytical statistics. Results: The participants’ age ranged from 16 to 31 years, with an average age of 19.84 ± 2.540 years. Moreover, most respondents (92.2%) identified as female. Approximately half (52.9%) reported no prior exposure to information on end-of-life care, and the majority (81.4%) had not attended any seminars, workshops, or conferences on the topic. The results indicated that participants' attitude notably enhanced following the palliative care course (M = 107.89, SD = 11.913), compared to their baseline (M = 100.80, SD = 10.435), t (101) = 4.903, p < 0.001.There is no significant difference in attitude between females (M = 108.96, SD = 12.157) and males (M = 101.25, SD = 6.228), t (100)=-1.768, P=.080. Similarly, individuals with prior awareness (M = 110.38, SD = 13.417) did not demonstrate a significantly higher attitude than those without (M = 106.56, SD = 10.229), t (100) =1.622, P=.108. Similarly, prior exposure to palliative care neither increased (M = 108.00, SD = 12.649) nor decreased (M = 108.43, SD = 11.879) respondents' attitudes significantly, t (100) =-.142, p=.887. Age of the respondents and the attitude were not significantly correlated, r (105) = .041, p = .686. Conclusions: This study aimed to test the effectiveness of a Palliative Care course in enhancing the attitudes of nursing students towards care of dying patients. The finding of this study will help serve as baseline data for policy makers and programmers to develop comprehensive course on attitude towards dying patients among the University nursing students.

The aim of this study was to evaluate the effect of the plant growth-promoting rhizobacterium, Azospirillum brasilense, on the hydroponic cultivation of basil (Ocimum basilicum L.). The trial was carried out in the Agricultural Microbiology laboratory of the Faculty of Agricultural Sciences of the National University of Catamarca located in the city of San Fernando del Valle de Catamarca (Argentina) and basil plants were grown in the hydroponic system of "Floating Root" where 3 treatments were established (T. 1: Inoculated with Azospirillum brasilense and commercial solution for hydroponics; T. 2: Control (commercial solution for hydroponics) and T. 3 = HAKAFOS (Commercial fertilizer solution). Plant height, root length and fresh weight of the aerial part at the time of harvest were recorded. The design was completely randomized with 3 replications; the data were subjected to analysis of variance and LSD test (p≤0.05). The plants inoculated with the bacterium Azospirillum brasilense (Pi 8 strain) produced plants with greater growth than the controls and with the use of commercial fertilizer. Implementing a hydroponic system for the production of basil using the bacterial inoculant of Azospirillum brasilense (Pi 8 strain) in the nutrient solution is very efficient and achieves rapid plant growth and produces a safe food.

Authors:   International Research and Training Center for Information Technologies and Systems of the NAS and MES of Ukraine, Smirnov Anton О.
Published: July 2024

Map representation and management for Simultaneous Localization and Mapping (SLAM) systems is at the core of such algorithms. Being able to efficiently construct new KeyFrames (KF), remove redundant ones, constructing covisibility graphs has direct impact on the performance and accuracy of SLAM. In this work we outline the algorithm for maintaining dynamic map and its management for SLAM algorithm based on Gaussian Splatting as the environment representation. Gaussian Splatting allows for high-fidelity photorealistic environment reconstruction using differentiable rasterization and is able to perform in real-time making it a great candidate for map representation in SLAM. Its end-to-end nature and gradient-based optimization significantly simplifies map optimization, camera pose estimation and KeyFrame management.

Introduction. Interest in the study of digital platforms (DP) is due to their prevalence and the dependence of this phenomenon on the possibilities of using information technologies. The growing distribution and great potential of the DP is connected not only with the use of new hardware and software, but also with the integration of digital technologies into business processes. The need for a deeper understanding of the differences and similarities of various CPUs prompts researchers to turn to the fundamental mechanism of knowledge organization – classification. From a practical point of view, the classification helps to compare different CPUs and allows users to choose the one that provides the desired results. Formulation of the problem. The problem of CPUs classification is to identify specific and common characteristics for building clusters using different approaches. When modeling and solving the classification problem, static methods and machine learning methods are used. The most widespread of them are the method of nearest neighbors and the method of support vectors. The theory of combinatorial optimization was used to build the mathematical model. The approach proposed. To build a mathematical model of the classification problem, the theory of combinatorial optimization was used, which allows to investigate some properties of this problem. The argument of the objective function in it is the division of the -element set into subsets. This combinatorial configuration can be either with or without repetitions, either finite or infinite. When finding the optimal result, a situation of uncertainty arises, which is related to the structure of the argument of the objective function which is a combinatorial configuration. Conclusion. The classification problem belongs to a broad class of partitioning problems. In it, the characteristics of the clusters are known, the objects that need to be determined, to which class they belong, are analyzed not simultaneously, but by groups or individual elements. Since the result is determined not simultaneously, but by a partial objective function, the classification problem belongs to the dynamic problems of combinatorial optimization. The classification of digital platforms is carried out by heuristic methods, in particular the nearest neighbor method. Both one and a set of common characteristics characteristic of certain CPUs are used as criteria.

Authors: Petrova N. , Kostadinova N. , Aleksiev G.
Published: July 2024

Abstract. Bulgarian animal husbandry has undergone several transformations since the country's accession to the EU. The declining levels of institutional support in recent years have necessitated the optimization of activities and the rational use of available resources. This requires the introduction of modern digital management methods for livestock farms. The aim of the present study is to assess the digitalization in supply planning for optimization of stocks in animal husbandry. To achieve this goal it is necessary to solve the following tasks: to analyze the problems in the cyclical supply of feed stocks; to study the models for optimization of stocks in animal husbandry; to assess the possibilities for digitalization of the processes of supply and management of feed stocks. The expectations from the research are that digitalization of the processes will optimize the supplies and stocks in animal husbandry, which is a prerequisite for efficiency and continuity of the production process. The results of the study show that consistently optimizing the existing, warranty, and preparatory stock is crucial for enhancing efficiency on any animal husbandry farm.

The vernacularization of the Qur'an has become an important area of study for Indonesian scholars. However, translations or interpretations in the local languages of eastern Indonesia, especially South Sulawesi, have received limited attention. This research aims to fill this gap by examining the development of Qur'anic interpretation in the Bugis language in South Sulawesi. Employing a descriptive-analytic method and a social-historical approach, the study reveals that all authors of Bugis-language interpretations originate from the Madrasah Arabiyah Islamiyah (MAI), established by Anregurutta (AG) H. As'ad. As a result, these authors demonstrate comparable perspectives, styles, methods, and ideologies, distinguishing the vernacularization efforts in South Sulawesi from those in other parts of Indonesia. The research highlights the crucial role of the As'adiyah Islamic Boarding School in fostering the Bugis tafsir tradition in eastern Indonesia. Additionally, it finds that the motivations for translating or interpreting the Qur'an into Bugis encompass the goals of deepening comprehension of Islamic teachings within the indigenous community and preserving the Bugis language and culture within the context of Islamic discourse. Ultimately, the study illustrates the harmony between Islamic teachings and the socio-cultural context in Indonesia by examining the efforts to adapt Islamic practices to the local setting in Bugis Land.

Benih ikan baramundi Lates calcarifer diperoleh dari pemijahan alami dengan jumlah induk terbatas sehingga variabilitas pertumbuhan dan kelangsungan hidup antar-batch menjadi tinggi. Penelitian dilakukan untuk menganalisis pertumbuhan dan mengevaluasi variasi genetik ikan kakap putih populasi Australia, Situbondo dan Lampung hasil domestikasi dan dibudidaya di hatcheri skala rumah tangga (HSRT). Sebanyak 10 ekor ikan barramundi dari setiap populasi digunakan untuk analisis variabilitas genetik dengan dua lokus mikrosatelit, yaitu Lca21 dan Lca32. Selanjutnya, data mikrosatelit diolah menggunakan software genetic analysis in excel (GenAlEx 6.51b2). Hasil yang diperoleh menunjukkan bahwa pertumbuhan panjang dan bobot tubuh serta laju pertumbuhan spesifik ikan baramundi dari Australia lebih tinggi dibandingkan dari Situbondo dan Lampung (P<0,05); sedangkan ikan baramundi dari Situbondo dengan Lampung adalah sama (P>0,05). Jumlah alel setiap lokus ikan baramundi berkisar 2-8 alel dan heterozigositas tertinggi dimiliki oleh ikan barramundi asal Situbondo (0,85), diikuti Lampung (0,65) dan paling rendah dari Australia (0,54). Dari hasil riset tersebut dapat disimpulkan bahwa ketiga populasi ikan baramundi hasil domestikasi dan dipeliharan dalam sistem HSRT memenuhi kelayakan untuk digunakan untuk kegiatan hibridisasi atau membentuk populasi awal (sintetis). Barramundi seeds, Lates calcarifer are usually sourced from natural spawning using a limited number of broodstock. Therefore, the growth and survival rate of these seeds vary greatly between batches. The research was performed to determine the growth pattern and genetic variations of barramundi seed populations produced from domesticated broodstock sourced from Australia, Situbondo, and Lampung and reared in small-scale hatcheries. Ten individuals of barramundi from each population were used for microsatellite analysis using two microsatellite loci, namely: Lca 21 and Lca 32. The resulted microsatellite data was processed using the genetic analysis available in Excel software (GenAlEx 6.51b2). The results showed that the growth in length and body weight as well as the specific growth rate of barramundi seeds produced from Australia broodstock were higher than that of Situbondo and Lampung (P<0.05) while the later two were similar (P>0.05). The number of microsatellite alleles ranged from 2-8 and the highest heterozygosity was obtained by barramundi seeds produced by Situbondo (0.85), followed by Lampung (0.65), dan Australia (0.54) broodstock. From the results of the research, it can be concluded that the three populations of barramundi fish, which were domesticated and reared in the HSRT system, meet the criteria for use in hybridization program or for forming a synthetic population.

Bakteri Edwardsiella tarda yang menginfeksi ikan patin dapat menyebabkan kematian hingga 80%. Terong asam (Solanum ferox) mengandung senyawa antibakteri yang dapat menghambat pertumbuhan bakteri dan dapat membunuh bakteri penyebab infeksi. Tujuan penelitian adalah untuk mengetahui pengaruh ekstrak S. ferox terhadap respons imun ikan patin jambal (Pangasius djambal) serta memperoleh dosis optimum untuk penanggulangan bakteri E. tarda. Metode yang dilakukan adalah eksperimen  dengan  rancangan acak lengkap  (RAL)  dengan  empat perlakuan  dosis ekstrak terong  asam (0, 300, 600, dan 900 ppm) serta kontrol (perendaman antibiotik komersial) dengan tiga ulangan. Ikan uji yang digunakan adalah ikan patin jambal berukuran 14-16 cm sebanyak 150 ekor. Perlakuan diberikan dengan perendaman ikan uji dalam larutan uji selama 7 hari. Parameter uji antara lain gejala klinis, total eritrosit, total leukosit, diferensial leukosit, aktivitas fagositosis, prevalensi, pertumbuhan bobot mutlak, dan  kelangsungan hidup. Hasil penelitian menunjukkan bahwa perendaman ikan patin jambal dalam larutan ekstrak S. ferox meningkatkan respons imun ikan patin jambal yang terinfeksi E. tarda..  Hasil penelitian ini menyimpulkan bahwa ekstrak S. ferox dosis 600 ppm secara efektif meningkatkan aktifitas fagositosis yang kemudian mengoptimalkan respons imun dan profil darah ikan patin jambal. Infection of Edwardsiella tarda bacteria in farmed catfish could lead to mass mortality of up to 80% of the fish. Sour eggplant (Solanum ferox) contains antibacterial compounds which are capable of inhibiting the growth of bacteria and can kill infectious bacteria. The study aimed to determine the effect of S. ferox extract on the immune response of catfish (Pangasius djambal) and obtain its optimum dose to control the infection of E. tarda. The study used an experimental trial in which treatments were arranged in a completely randomized design (CRD) consisting of four treatment doses of sour eggplant extract (0, 300, 600, and 900 ppm) and control (immersion of commercial antibiotic) with three replicates. The test fish used were 150 catfish with a length of 14-16 cm. The treatments were applied by soaking the test fish in the test solutions for 7 days. The measured parameters included clinical symptoms, total erythrocytes, total leukocytes, leukocyte differential, phagocytic activity, prevalence, absolute weight growth, and survival. The results showed that the immersion of catfish in S. ferox extract solution increased the immune responses of catfish infected by E. tarda.  The results of this study concluded that S. ferox extract at a dose of 600 ppm effectively increases phagocytic activity which then optimizes the immune response and blood profile of catfish.
