Authors: Vinasyiam Apriana , Suprayudi Muhammad Agus , Alimuddin ,
Published: September 2023

ABSTRACT The specific activity of the digestive enzymes, namely: pepsin, amylase, lipase, trypsin, and chymotrypsin were studied in Nile tilapia Oreochromis niloticus fed diet supplemented with recombinant Ephinephelus lanceolatus growth hormone (rElGH). The results showed that fish treated with rE1GH showed lower lipase and chymotrypsin specific activities (P>0.05), while the trypsin/chymotrypsin specific activity (T/C ratio) was found higher compared to control fish. Moreover, higher protein digestibility, higher protein retention and a lower ammonia excretion rate were measured for rE1GH treated fish. Oral rElGH administration enhanced Nile tilapia growth up to 20.04%, without affecting survival. This study suggested that rapid growth performance induced by rElGH was linked with T/C ratio rather than the specific activity of other digestive enzymes. Keywords: recombinant growth hormone, digestive enzyme, digestibility, Oreochromis niloticus  ABSTRAK Aktivitas spesifik enzim pencernaan pepsin, amilase, lipase, tripsin, dan kemotripsin diamati pada ikan nila Oreochromis niloticus yang diberi pakan mengandung hormon pertumbuhan rekombinan ikan kerapu kertang Ephinephelus lanceolatus (rElGH)). Hasil menunjukkan bahwa ikan uji pada perlakuan rElGH memiliki aktivitas spesifik enzim lipase dan kemotripsin yang lebih rendah, sedangkan rasio tripsin/kemotripsin (rasio T/C) yang lebih tinggi dibandingan ikan kontrol. Kecernaan protein dan retensi protein bernilai lebih tinggi sementara laju ekskresi amonia bernilai lebih rendah pada ikan perlakuan. Pemberian rElGH secara oral mampu mempercepat laju pertumbuhan ikan nila hingga 20,04% tanpa memengaruhi kelangsungan hidup. Berdasarkan penelitian ini, dapat disimpulkan bahwa laju pertumbuhan cepat yang diinduksi oleh rElGH berhubungan dengan rasio T/C dibandingkan dengan aktivitas spesifik enzim pencernaan lain. Kata kunci: hormon pertumbuhan rekombinan, enzim pencernaan, kecernaan, Oreochromis niloticus

ABSTRACT Snakehead fish Channa striata is one of freshwater commodity which has high economic value. Nowadays, snakehead fish stock mostly comes from wild capture. Artificial spawning with hormonal induction is usually used to improve broodstock efficiency, as well as the quality and quantity of fish seed production. Purpose of this study was to determine the effectiveness of prostaglandin 2α (PGF2α) hormone on ovulation time and count of ovulated eggs. This experiment used 30–40 cm broodstock with 600–900 g body weight. Fishes were acclimated for one week in a container and then injected with different doses of PGF2α, namely: control without PGF2α (P1), 0.5 mL/kg (P2); 0.7mL/kg (P3); and 0.9 mL/kg (P4). Each treatment consisted of three fishes as replication. Ovulation time was observed until 72 hours post injection. The results showed that PGF2α injected broodstoks ovulated faster (9.17–12.24 hours post injection) than control P1 (22.67 hours), while among PGF2α injected fishes were the same. Furthermore, count of ovulated eggs from PGF2α induced broodstocks were higher than control P1, and the highest (2,860 eggs) was obtained in treatment 0.9 mL/kg. Thus, PGF2α at dose of 0.9 mL/kg can be used to induce eggs ovulation of snakehead fish and to increase count of ovulated eggs. Keywords: PGF2α, ovulation time, ovulated eggs count, Channa striata  ABSTRAK Ikan gabus Channa striata merupakan salah satu komoditas air tawar yang mempunyai nilai ekonomi tinggi.

Published: September 2023

A short-term soil incubation experiment was set up to obtain information to clarify the effect of our developed organic composite fertilizer on soil nitrogen mineralization. The composite was designed to have beneficial effects on the properties of chicken manure and to improve soil water management properties in addition to organic matter replenishment. In the incubation experiment, two different additives, bentonite, and super absorbent polymer, were used to enhance the properties of fermented chicken manure. Developed prototype products were tested in a four-week-long soil incubation experiment in two typical Hungarian soils: brown forest soil with a sandy texture and chernozem soil at two different water capacities (40 w/w % and 60 w/w %). Soil pH, and inorganic nitrogen forms, like nitrate and ammonium, were measured weekly. Furthermore, the potentially mineralized nitrogen and net mineralization rate were calculated. The applied composite was not affected the soil pH significantly in the examined period. The soil nitrate and ammonium ratio was changed during the incubation as the ammonium content in the soil decreased while nitrate content increased continuously throughout the experiment. This suggests that the incubation experiment successfully monitored the delicate balance of soil nitrogen forms. It was found that the chernozem soil type had a higher mineralization potential compared to brown forest soil due to its higher nutrient and organic matter contents. Moreover, our results pointed out that soil moisture content did not significantly affect the mineralization process. The amount of mineral nitrogen, generated per week can be described by a linear relationship for both soil types and water regimes. The composite product showed efficacy in promoting mineralization processes, particularly in soils with low nutrient status and mineralization potential.
Closed plant production systems in vertical farms for a circular economy
Authors:   Osaka Metropolitan University, Japan, Kitaya Yoshiaki
Published: September 2023

The reuse, recycling and control of emissions from large-scale food waste in urban areas have gained increased attention in recent years. Developing efficient food production systems with a low environmental impact is an important issue in facility-based plant production systems, such as plant factories, as part of efforts to add more value to plant production from an environmental perspective. Plant production plays an important role in human health and welfare, particularly in urban areas. To produce food efficiently while protecting the environment, it is imperative to establish a material-cycling farming system to promote a material-cycling-oriented society. In this chapter, the author proposes three possibilities and perspectives for facility-based plant production systems with the circulation of materials to achieve a sustainable balance between food production and environmental protection.

Authors:   Japan Plant Factory Association, Japan, Hayashi Eri
Published: September 2023

Plant factories with artificial lighting (PFALs), with an almost airtight and well-insulated structure, enable simple and accurate data acquisition and environmental control, time series analysis, and prediction related to plant phenotypes. With plant phenotyping based on cohort research in PFALs, the life cycle phenome history of both plant individuals and communities can be obtained non-invasively and continuously and analyzed from seed sowing to harvesting, with time series data on the microenvironment, management, and resource inputs/outputs. This chapter first reviews challenges affecting PFALs and introduces plant phenotyping in general, along with previous plant phenotyping studies in PFALs. Plant phenotyping based on plant cohort research in PFALs is also discussed, followed by experimental cohort research studies on individual phenotyping. Finally, the possibility of plant phenotype-based environmental control in PFALs, considering business-related factors, is discussed.

Authors:   Wageningen University & Research, The Netherlands, Jin Wenqing ,   Priva B.V., The Netherlands, Li Hua ,   Wageningen University & Research, The Netherlands
Published: September 2023

Light-emitting diodes (LED) are advancing the development of indoor vertical farming due to their varied light spectrum and photon flux density. The substantial energy cost of lighting systems requires improvement. This chapter reviews three major spectra applied to lettuce cultivation in indoor vertical farming systems. Red and blue light are the most efficient spectra for chlorophyll absorption and far-red light promotes light interception and increases photochemical efficiency. Research shows that the photon flux ratio between red and blue light affects plant architecture, leaf and photosynthetic characteristics, biomass production and phytochemical compound accumulation. Additional far-red over photosynthetically active radiation triggers shade avoidance responses and increases light interception, which combines with planting density effects. Aside from the above spectra, biomass production and quality, utilization of other light spectrum and dynamic lighting as well as plant modelling should be considered to promote light use efficiency in indoor vertical farming.

Determination of Atterberg Limits using the vane shear test method
Authors: KAYABALI Kamil , NAGARAJ H.b. , YILMAZ Deniz , BEYHAN Muhammed
Published: September 2023

Atterberg limits are important index parameters used to classify soils for various engineering applications. Engineering properties of soils are predicted through simple correlations with index properties and thereby the engineering behavior of soils are qualitatively assessed. There are two popular methods of determining liquid limit, and plastic limit is commonly determined adopting rolling thread methods. To avoid operator related variations in determining plastic limit by conventional method, some researchers have explored using cone method as an alternative. However, there is no consensus about the depth of penetration to reckon the end of plastic state. Though various other test methods have been developed to determine plastic limit (like roll plate device), cone penetration with its limitation of determining plastic limit, is the only method to determine both liquid and plastic limit of soils. Since laboratory vane shear test is a simple and reliable method of determining undrained strength of fine-grained soils, the authors have explored to determine both liquid and plastic limits through correlations developed between undrained strength and water content over a range of consistencies between liquid and plastic states. This would eliminate determining liquid and plastic limit separately without sacrificing the reliability of results.
Children of the Caliphate: Young IS Returnees and the Reintegration Challenge
Authors: van der Heide Liesbeth , Geenen Jip
Published: September 2023

This research paper focuses on young or juvenile Islamic State (IS) returnees, assessing what sets juvenile returnees apart from adult returnees or the broader population of young criminals, and scoping the potential venues and challenges in their rehabilitation and reintegration. The authors conclude that rehabilitation and reintegration efforts for juvenile violent extremist offenders (including those returning from IS-territory) need to be based on two underlying assumptions: the importance of age and attitudes. Young children (zero to nine years old) who are born in IS-territory or brought by their parents at a very young age, should first and foremost be viewed as victims. For older children, other factors such as indoctrination, training and potential involvement in violent activities are more likely to play a role, demanding an approach that goes beyond the victim-perspective. Professionals need to determine to what extent these children have been socialised into IS-culture and whether they cope with their experiences more internally or externally. To direct rehabilitative efforts for them, it is even more essential to assess their attitude towards violence and to what extent they have accepted IS’ norms and behaviors, compared to adult terrorist returnees. In the end, the authors conclude that it is not necessary to reinvent the wheel, especially where numbers of terrorism convicts in general, and juveniles in particular are low. But rehabilitation is considered to work best when tailored to individual needs, and policymakers need to take into account the very distinctive needs of juvenile offenders as a separate class of offenders while respecting all relevant international law and human rights standards in the fight against terrorism.

The system of pedagogical assessment in higher education: from formalized to creative approach
Authors:   North-Western Institute of Management, branch of RANEPA, Vylkova Elena S.
Published: September 2023

In modern conditions, the development strategy of the domestic system of higher education involves a focus on the harmonious development of the individual and his creative abilities. However, the current system of pedagogical assessment in most universities, based on a point-rating system for assessing the knowledge, skills and abilities of students, is excessively formalized. The problem is that there is an urgent need to give the point-rating system a more creative content. The methods of research are the analysis of publications on the subject of the point-rating system and the identification of white spots in this subject field. An option is proposed to supplement the existing system of pedagogical assessment in higher education with a system of markers of students’ achievements, with their conversion at the end of the semester into bonus points. Such a system of fixing the super successes of students is designed to take into account their ability and desire to learn, diligence, interest in mastering new knowledge, breadth of horizons, involvement in the educational process. It also makes it possible to fully implement an individual approach to the assessment of the learning process and its results in relation to each specific student and take into account his various abilities in mastering certain competencies. The transition to an innovative point-bonus system of pedagogical assessment of training and its results allows you to add a creative, creative component to the formalized point-rating, as well as to any other assessment system. When introducing a point-bonus system in institutions of higher education, it is required to take into account their features based on the specifics of the areas of training, specialties and specializations, the region of the location of the university and other factors. In the context of a changing world and pedagogical paradigms, the point-bonus system of pedagogical assessment is designed to contribute to the improvement of higher education in Russia in the direction of the formation of a creative and creative personality of the teacher.
Problems of scientometrics: Maximum cited publication index as a means of solving some of them
Authors:   Glazov State Pedagogical Institute n.a. V.G. Korolenko, Ershteyn Leonid B. ,   Yaroslav-the-Wise Novgorod State University
Published: September 2023

The paper presents a critical analysis of scientometrics as an indicator of scientist’s effectiveness. Six points of criticism of the main scientometric indices clearly show that scientometrics cannot be an indicator of such efficiency. In particular, attention should be paid to the problems of accrual, PR, negative citation, citation of non-scientific publications, publication only in trend areas, co-authorship, and article lifetime. An empirical analysis of the effectiveness of scientometrics is conducted and its ineffectiveness is substantiated. It is explained why, despite all the shortcomings of scientometrics, it continues and is likely to be used in the assessment of scientific activity. It is argued that not many scientists in their lives separately make significant discoveries, most of them work in scientific teams and narrow areas of science. On this basis, the ‘maximum cited publication index’ — the MCP index — is introduced. This index is calculated as the number of citations of a maximally cited work divided by the number of its co-authors. It is proved that, on the one hand, the MCP index really better shows the scientist’s contribution to science, and, on the other hand, it will solve some problems of scientometrics, such as the problem of co-authorship and accrual. An empirical verification of the MCP index is given.

Authors:   Ural State University of Railway Transport, Rybkina Svetlana N.
Published: September 2023

The article identifies the factors that determine the need to expand the scope of linguistic and intercultural competencies of subject-matter specialists — translators or interpreters and teachers of foreign languages trained in linguistic universities, towards multilingualism and multiculturalism. The relevance of addressing this topic is due to professional activities of the named subject-matter specialists in the conditions of polyglossia, which is characteristic both for educational and scientific environment of recent decades, and for the sphere of international and interstate relations. Author names the main circumstances associated with the organization of teaching foreign languages in modern universities. These circumstances, from her point of view, hinder implementation of shift towards multilingualism and multiculturalism in training the above named specialists. The solution of the outlined problem, according to the author, is primarily associated with governmental regulation in this area, as well as taking into account international experience in studying foreign languages and applying best methods for teaching them in conditions of university polyglossia.

The text of the article analyzes the causes of the increasing number of cases of youth terrorism and extremism. Against this social background, there is an increase in cohesion among population groups that are not directly involved in terrorist operations, while they have long-term traumatic consequences that cause changes in their behavioral attitude and life direction, increasing feelings of guilt. Patriotic education requires a unified State policy to prevent acts of extremism and terrorism among young people. The State should be the central institution that organizes and ensures the functioning of the entire system of patriotic education. The patriotic education system of young people makes it possible to form and develop socially significant values, such as citizenship and patriotism. These qualities are formed during education and training in the process of public patriotic actions. Patriotic activity in educational institutions requires constant improvement.

Published: September 2023

Background and Objectives: Romania ranks among the countries with a notably high rate of preventable deaths due to inadequacies in prevention, screening, early detection, and timely management processes. Cervical cancer (CC) is a significant contributor to these preventable deaths, particularly affecting patients from marginalized backgrounds, rural regions, and the Roma population. The purpose of this article was to identify correct and consistent information of the Roma population about the risk of CC, as well as the importance of understanding the causes of the disease and awareness of the available prevention methods. Materials and methods: A cross-sectional study was conducted using a self-administered questionnaire applied only to Roma women in Romania. Results: We enrolled 759 patients in the study. These were divided into 2 groups, Group 1 comprised 289 (38.1%) women who had been tested for HPV infection, while Group 2 included 470 (61.9%) women who had never been tested for HPV infection. Characterization of women in Group 1: mostly aged between 25-54 years, with high school education, married, who started sexual activity under the age of 18 years, with only one sexual partner and with over 5 pregnancies. Regarding contraceptive methods, 35.7% of women do not know/ use any contraceptive method, and 32.2% use hormonal contraceptives. Two thirds of the women tested had heard of HPV, and 19.7% were vaccinated against HPV with at least 2-3 doses. A percentage of 8.7 had a diagnosis of CC, compared to those who were not tested (p-0.0001), whereas 63% of the tested women do not know much about CC, as opposed to 85.7% of the group of untested women. Conclusion: Cervical cancer (CC) continues to be a public health issue in Romania, particularly in patients belonging to vulnerable groups. Promotion campaigns for HPV vaccination and CC screening are necessary to reduce the associated mortality and morbidity.
Pre-Launch Spectral Calibration of the Absorbed Aerosol Sensor
Authors: Mao Jinghua , Wang Yongmei , SHI Entao , Wang Jinduo
Published: September 2023

Spectral calibration consists of the calibration of wavelengths and the measurement of the instrument's spectral response function (SRF). Unlike conventional slits, the absorbed aerosol sensors (AAS) are used as a slit homogenizer, in which the spectral response function (SRF) is not a conventional Gaussian curve. To be more precise, the SRF is the convolution of the slit function of the spectrometer, the line spread function of the optical system, and the detector response function. The SRF of the slit homogenizer is a flat-topped multi-Gaussian function. Considering the convenience of fitting, a super-Gaussian function, which looks like a similar distribution to the flat-topped multi-Gaussian function, is used to fit the measured data in a spectral calibration. According to the results, the SRF’s shapes, due to the Earth port, resemble a Gaussian curve with a flatted top could be concluded, which contains an FWHM of 1.78–1.82 nm for the AAS. The results show that the correlation coefficients are about 0.99, which proves that the fitting function could better characterize the SRF of the instrument.

Brassicaceae are well known as non-arbuscular mycorrhizal (AM) host plants. This study was aimed to examine effects of two Brassica; cabbage (Brassica oleracea L. cv. cabitata) and mustard (B. juncea Coss.) on three AM species (Acaulospora, Entrophospora and Glomus) and to examine effect of root incorporation into soil on root AM infectivity in maize growing in iron toxicity soil. Experiment 1, cabbage and mustard crop reduced spore density of Acaulospora, but there was no effect on spore density of Entrophospora. While, mustard crop had more effect on Glomus spore density than cabbage crop. Experiment 2, AM spore from two conditions; without and with 6 weeks of root residues (cabbage, mustard and maize) incorporation was examined for its infectivity in maize roots. At D21, without root incorporated, the infectivity of Acaulospora, Entrophospora and Glomus were not different. By contrast, cabbage and mustard root incorporation depressed infec-tivity of Acaulospora but, there was no effect on Entrophospora. Whereas, cabbage root incorporation only depressed infectivity of Glomus. However, AM infectivity was recovered at D42. These results suggested that Brassica root incorporated into soil was the actual effect on the viability of AM spore resulting in reduction of AM infectivity at the early stage.
Fuzzy Replenishment Policy using PFN with Weibull deterioration of Partially Shortages in Time -Pricing and Promotional Effort demand
Authors: Vel Sivan
Published: September 2023

This paper aims to develop a replenishment policy for deteriorating items with Weibull distribution time varying deterioration over a defined time horizon. Market demand for the ordered item is determined by time, promotional activities, and selling price, according to the proposed model. The shortages and excess demand is partially backlogged. Additionally, as time passes, the backlog rate decreases. Approximate expressions are given for determining the scheduling period, maximum inventory level and average total relevant cost. The Total Relevant Cost (TRC) is derived, resulting of TRC two different types of environments namely crisp and Fuzzy are observed. The TRC is fuzzified with pentagonal fuzzy numbers and defuzzified using the Signed Distance Method. The primary goal of this research is to determine the best solution by reducing ordering cost and cycle times, promotional costs, optimum order quantity and average total relevant cost.

The production of oil by thraustochytrids is still costly because of its necessary and expensive culture medium. We evaluated the growth, lipid production, and fatty acid composition in an inexpensive, molasses-based (M) medium. Newly isolated thraustochytrid strains were identified as members of genus Aurantiochytrium based on 18S rRNA gene sequences. Isolated strains were repeatedly cultured in M medium for acclimatization to the medium. Acclimatized and non-acclimatized strains were cultured in basal GY medium and M medium. The lipid in the cultured cells were extracted by the Folch method, and the fatty acid composition was analyzed by gas chromatograph. The growth and lipid production in the non-acclimatized strains were significantly inhibited by culturing in M medium, whereas the growth and lipid production were improved by acclimatization treatment in the same medium. The fatty acid composition in the cultured cells were affected by the M medium compared to the basal GY medium. The production of some enzymes such as leucine and valine aryl-amidase was suppressed in the M medium, and the activities recovered by acclimatization treatment. The growth of some strains in the molasses medium was thus recovered by the acclimatization process, and the profiles of extracellular enzymes were also affected.

Growing incidence of myopia worldwide justifies the search for efficient methods of myopia prevention. Numerous pharmacological, optical, and lifestyle measures have already been utilized, but there remains a need to explore more practical and predictable methods for myopia control. This paper presents a review of the latest literature on preventing the progression of myopia using Defocus Incorporated Multiple Segments Spectacle Lenses (DIMSsl), Repeated Low-level Red-Light Therapy (RLRL), and the combination of low-dose atropine (0.01%) with orthokeratology lenses.

Hemoglobin levels, hematocrit, and erythrocyte count all decline in anemia, which is characterized by a reduction in the number of erythrocyte masses. Iron deficiency, also referred to as iron deficiency anemia, is the most typical cause of anemia. According to the 2018 Basic Health Research (Riskesdas), anemia affects 3–4 out of 10 teenagers in Indonesia based on the characteristics of age groups 5–14 years and 15–24 years, respectively. The Pariaman City Hospital's interne chamber was the location of the community service project, which was carried out in April 2023 with a target audience of 15 patients and their families. In order to change preventative behavior and improve health status, the goal of this community service is to promote patient and family understanding about anemia prevention and management. The process for carrying out community service is divided into three stages: planning, carrying out, and evaluating. According to the findings of the community service project, the patient's family had a low level of awareness about the prevention and management of anemia before receiving counseling (pre-test) and a high level of knowledge after receiving counseling (post-test). The hospital is advised to keep offering ongoing health education to patients' families regarding the prevention of anemia and discharge planning for patients with reference to managing a healthy diet and nutrition.

 

Abstrak

Anemia adalah keadaan dimana terjadi penurunan jumlah masa eritrosit yang ditunjukkan oleh penurunan kadar hemoglobin, Hematokrit dan hitung eritrosit. Penyebab paling umum dari anemia adalah kekurangan zat besi atau yang disebut dengan anemia defisiensi zat besi. Riset Kesehatan Dasar (Riskesdas) 2018 menunjukkan anemia di Indonesia menurut karakteristik umur 5-14 tahun sebesar 26,8% dan umur 15-24 tahun sebesar 32,% artinya 3-4 dari 10 remaja menderita anemia. Pelaksanaan pengabdian masyarakat dilaksanakan pada bulan April 2023 dengan sasaran Pasien dan Keluarga Pasien di ruangan Interne RSUD Kota Pariaman berjumlah 15 orang.  Tujuan Pengabdian masyarakat ini adalah untuk meningkatkan pengetahuan pasien dan keluarga pasien terhadap pencegahan dan penatalaksanaan anemia sehingga adanya perubahan perilaku yang bersifat preventif dalam meningkatkan derajat kesehatan. Metode dalam pelaksanaan pengabdian masyarakat dengan tiga tahap yaitu tahap perencanaan, tahap pelaksanaan dan tahap evaluasi. Hasil pengabdian masyarakat didapatkan bahwa tingkat pengetahuan keluarga pasien tentang pencegahan dan penatalaksanaan Anemia sebelum diberikan penyuluhan (Pre test) adalah rendah yaitu sebesar 66.7 % dan setelah diberikan penyuluhan (post test) meningkat menjadi tinggi yaitu sebesar 86.6 %. Disarankan kepada pihak rumah sakit agar terus memberikan promosi kesehatan secara berkesinambungan kepada keluarga pasien terkait pencegahan anemia dan discharge planning bagi pasien  dalam mengatur pola makan serta gizi yang seimbang.

Community service activities are carried out in an effort to strengthen women's capacity so they can develop the jumputan batik home industry and the millennial version of natural fashion designs. Operationally the product of community service activities is jumputan cloth using natural dyes. The training materials for community service activities are the skills of making jumputan batik patterns with natural characteristics, as well as green campaigns on environmental preservation and sustainable lifestyles through getting used to implementing 7R (recycle, reuse, reduce, replace, repair, replant, refill). Counselling on environmental materials in sustainable development was delivered in a planned manner to 27 Coastal Communities in the North Jakarta Region virtually. The community is expected to be able to design skills. In the virtual process, they have shown: enthusiasm, collaboration, curiosity, participation in providing ideas, discipline, new ideas, creativity, interest, ability to express opinions and motivation. The millennial version of natural character fashion products can soon be widely promoted at the local, regional, national and global levels. Demand for fashion products with coastal batik motifs with a millennial version of nature shows the high enthusiasm of coastal communities in North Jakarta for products with the concept of supporting a circular economy by implementing the 7R.
