We conducted a systematic analysis of the studies, which utilized the methods of cognitive function assessment in Russianspeaking practice for the identification of cognitive impairments in patients with substance use disorder and HIV infection. We searched the relevant studies in the following electronic database: ELIBRARY, PubMed, Embase, and PsycInfo (searched in April 2020). We included articles published in the past 20 years (from 2000 to 2020). The literature review, data extraction, and presentation were conducted based on the PRISMA statement. The majority of the papers included cross-sectional studies. In the studies, they included patients with substance use disorder, the co-occurrence of HIV infection was not controlled as a potential confounder. Researchers applied qualitative or quantitative methods and their combination, as well as screening instruments. The most popular cognitive assessment methods in research among the Russian-speaking population included the following: Luria memory words test, Schulte table, WAIS subscales, and Mini-Mental State Examination (MMSE). The important future direction is the development of the standardized assessment specifically designed to use in patients with substance use disorder, including those who also live with HIV infection.

The research aimed to study the frequency of class G antibodies` formation to SARS-CoV-2 in HIV-infected patients in response to immunization with the Gam-COVID-Vac vaccine and the reactogenicity of the vaccine.Materials and methods. 36 HIV-infected and 38 HIV-negative volunteers were vaccinated. The inclusion criteria for patients were: age 18 years and older; absence of earlier disease COVID-19; negative test of the presence of RNA in a smear from the nasopharyngeal and oropharyngeal mucosa and IgG in blood serum to SARS-CoV-2, absence of contraindications, undetectable viral load. The number of CD4+ lymphocytes in the blood of HIV-infected people before vaccination was 520,0±9,6. It was used the two-dose vaccine Gam-COVID-Vac, developed by National Research Center named after N.F. Gamaliel. The interval between the administration of the vaccine was 24,2±0,5 days. The presence of IgG before vaccination and 44–54±0,6 days after the start of vaccination to SARS-CoV-2 coronavirus was determined by enzyme immunoassay using the SARS-CoV-2-RBD-ELISA-Gamaleya test system. The positivity index (PI) was calculated for each test sample. The sample was considered positive at IP>1.Results. The presence of antibodies in HIV-infected patients was detected in 75,0% cases, in HIV-negative — in 92,1% cases, the arithmetic average of the positivity index was 10,3±1,9 in the observation group, 15,3±1,9 in the comparison group (c2=3,9; p=0,04). There are no postvaccinal complications registered in patients of both groups. The frequency of general reactions to the introduction of the first and (or) second components of the vaccine in the group of HIV-infected and HIV-negative did not differ and amounted to 8,3 and 13,2%, respectively. Local reactions among HIV-infected (in 19,4% of cases) were less common than among HIV-negative (in 47,4% of cases) (c2=6,4; p=0,01).Conclusion. Humoral immunity in response to immunization of Gam-COVID-Vac against SARS-CoV-2 in HIV-infected with minor immunosuppression is less pronounced than in HIV-negative. However, the production of postvaccinal class G immunoglobulins in HIV-infected patients in 75,0% of cases and the weak reactogenicity of the vaccine it is recommended for using in people living with HIV on the back of effective antiretroviral therapy.

Study of the peculiarity of HIV spread, first of all in the cities led to the formulation of syndemic concept — mutually enhancing set of social, behavioral and biological characteristics of which most frequently mentioned is a combination of substance abuse, victimization (experience of violence) and presence of HIV-infection or AIDS (SAVA syndrome). The prevalence of this syndemic is not studied in detail in Russian Federation.The goal of the present study was to evaluate the prevalence of this syndrome and its components among injecting drug users in six cities in the Russian Federation.Results and discussion. The summary prevalence of the full SAVA was 12,3% (95% CI=10,0–14,.6%), but there were significant differences between cities especially between St. Petersburg and Krasnoyarsk (18,9% vs 6,7%, р=0,031). Prevalence of incomplete SAVA syndrome (without the mandatory presence of HIV/AIDS) was 66,0% (95% CI=62,4–69,6%) the and majority of respondents (96,8%) had up to 4 SAVA components. There were no statistically significant differences in SAVA prevalence depending on gender. SAVA is relatively highly prevalent among IDU in participating cities and does not relate to respondents’ gender.

The symptomatology of these negative phenomena is quite diverse, covers the dysfunction of many organs and systems, and deserves the formulation of polymorphism of secondary and delayed complications. They are based on the consequences of the transferred acute phase of inflammation, systemic prolonged metabolic and structural disorders, including the studied genetic disorders. Possible causes of polymorphism of disorders and their manifestations in the postcovid period are considered.
Structural Evolution of the Ancient Enzyme, Dissimilatory Sulfite Reductase
Authors: Colman Daniel R. , Labesse Gilles , Gurla Swapna , Stefanakis Johanna , Montelione Gaetano , Boyd Eric S. , Royer Catherine
Published: January 2022

Dissimilatory sulfite reductase is an ancient enzyme that has linked the
global sulfur and carbon biogeochemical cycles since at least 3.47 Gya.
While much has been learned about the phylogenetic distribution and
diversity of DsrAB across environmental gradients, far less is known
about the structural changes that occurred to maintain DsrAB function as
the enzyme accompanied diversification of sulfate/sulfite reducing
organisms (SRO) into new environments. Analyses of available crystal
structures of DsrAB from Archaeoglobus fulgidus and
Desulfovibrio vulgaris, representing early and late evolving
lineages, respectively, show that certain features of DsrAB are
structurally conserved, including active siro-heme binding motifs.
Whether such structural features are conserved among DsrAB recovered
from varied environments, including hot spring environments that host
representatives of the earliest evolving SRO lineage (e.g., MV2-Eury),
is not known. To begin to overcome these gaps in our understanding of
the evolution of DsrAB, structural models from MV2.Eury were generated
and evolutionary sequence co-variance analyses were conducted on a
curated DsrAB database. Phylogenetically diverse DsrAB harbor many
conserved functional residues including those that ligate active
siro-heme(s). However, evolutionary co-variance analysis of monomeric
DsrAB subunits revealed several False Positive Evolutionary Couplings
(FPEC) that correspond to residues that have co-evolved despite being
too spatially distant in the monomeric structure to allow for direct
contact. One set of FPECs corresponds to residues that form a structural
path between the two active siro-heme moieties across the interface
between heterodimers, suggesting the potential for allostery or electron
transfer within the enzyme complex. Other FPECs correspond to structural
loops and gaps that may have been selected to stabilize enzyme function
in different environments. These structural bioinformatics results
suggest that DsrAB has maintained allosteric communication pathways
between subunits as SRO diversified into new environments. The
observations outlined here provide a framework for future biochemical
and structural analyses of DsrAB to examine potential allosteric control
of this enzyme.
Revisiting Michael Bonell’s humid tropical rainforest catchments: isotope tracers reveal seasonal and inter-annual shifts in catchment hydrology
Authors: Lim Hanshe , Munksgaard Niels , Zhou Xi , Bird Michael
Published: January 2022

It has been almost 50 years since Mike Bonell’s foundational work in the
humid tropics, kickstarting the field of tropical hydrology. In order to
expand on this work and build a more generalized hydrological
understanding of steep rainforest catchments, we studied the seasonal
and inter-annual evolution of hydrological response from two catchments
with similar characteristics to those studied by Bonell. Both
hydrometric and water stable isotope data were collected at relatively
high frequencies during one wet season (Thompson Creek) and a three-year
period (Atika Creek). The longer dataset spans a wide range of
environmental conditions experienced in the humid tropics, including
events that cover the wetting-up transitional period of the wet season,
ENSO events and tropical cyclones. Both catchments displayed fast
streamflow response to rainfall with the shallow upper soil profile
responding quickly to rainfall at Atika Creek. New findings from this
study include the importance of pre-event water (>50%) for
overall event flows, especially when the catchment was wet. Rainfall,
surface runoff and groundwater isotope compositions varied between
rainfall events with the most complex mixing plots observed for
multi-peak events that occurred at the start of the wet season and after
a dry period within the wet season. Inter-annual variability in
catchment hydrology reflected changing ENSO conditions and the 2020-21
La Ninã wet season was characterized by several tropical cyclone events
which generated the most 18O-depleted rainfall and streamflow isotope
values. Our findings highlight the requirement for high frequency
multi-source sampling to accurately interpret catchment behavior. We
propose a conceptual model to describe the seasonal evolution of
streamflow response in steep rainforest catchments.

Published: January 2022

BACKGROUND: Few studies have examined survival in relapsed childhood
acute lymphoblastic leukemia (ALL) in resource-limited countries. The
aims of this study were to evaluate the incidence, prognostic factors,
and survival of relapsed childhood ALL in Thailand. METHODS: The medical
records of patients with ALL aged <15 years in the major
tertiary care institution in Southern Thailand between January 2000 and
December 2019 were retrospectively reviewed. The Kaplan-Meier method was
used to depict the overall survival (OS). RESULTS: A total of 472
patients with ALL were enrolled. The incidence of relapsed ALL was
32.8%. Of the 155 relapsed patients, 131 (84.5%) and 24 (15.5%) had
B-cell and T-cell phenotypes, respectively. One hundred thirteen
(72.9%) and 42 (27.1%) patients had early and late relapses,
respectively. The most common site of relapse was bone marrow in 102
patients (65.8%). One hundred twenty-eight (82.6%) and 27 (17.4%)
patients received or refused the relapse chemotherapy, respectively. The
5-year OS of all relapsed patients was 11.9%. The 5-year OS among the
patients with early relapse was significantly lower than in the patients
with late relapse (5.3% vs. 29.1%, respectively, p <0.0001).
Site and immunophenotype were not associated with survival of relapsed
ALL. The patients who refused chemotherapy had a median survival time of
3.1 months. CONCLUSION: The relapse rate was one third of patients with
ALL. The 5-year OS was 12% and patients who refused chemotherapy had a
median survival time of 3 months.

Published: January 2022

Water quality impairment due to anthropogenic activities affects fishery resources. Surface water bodies in the Niger Delta Region of Nigeria are being adversely impacted by the effects of pollution and the destruction of its fishery resources. This study was carried out to assess the impacts of anthropogenic activities on the fish compositions and diversity of Okerenkoko Estuarine, Delta State, Nigeria. Okerenkoko Estuarine (62.79 Km) was spatially stratified into five stations (Z1, Z2, Z3, Z4 and Z5) based on nearness to major anthropogenic activities. Temporal stratification covered June to December. Fish samples were collected for 7 months from each station at the study area with prior arrangement with the fishers. Fishing gears used were Mid – Water Drift Gill Net of mesh sizes 101 mm and 127 mm; Bottom Set Gill Net (50 – 100 m) of mesh size 76 mm, 101 mm and 127 mm; Hook and line (2 – 6 m) of hook sizes No. 5, No. 7, No. 8, No. 9, No. 12 and No. 15; Long Line (300 – 1000 m) of hook sizes No. 7, No. 8. Parameters determined were Numbers of Species, Abundance (%), Simpson and Shannon by using standard procedures. Data were analysed by using Excel (Window 10) and Palaeontological Statistics (Past Version 3.6). A total number of 1261 of fishes and 45 species belonging to 14 families were identified. Highest 383 (30.4 %) and least 152 (12.1 %) number of fishes were obtained in Z5 and Z4, respectively. The most abundant fish species recorded was Sardinella aurita 192 (15.2 %), while the least was Sphyraena afra 1 (0.1 %), respectively. Temporally, the highest 331 (26.2 %) and least 45 (3.6 %) fish species Occurred in December and September. Simpson index ranged from 0.69 to 0.89 in Z1 and Z3, Shannon (1.97, 2.98) occurred in Z4 and Z2, respectively. Fish biodiversity richness (0.69) of Okerenkoko Estuarine could be threatened.

Published: January 2022

No doubt, the entire world is gaining momentum into digital media information. This is making Information and Communication Technologies (ICTs) an important aspect of the development. Presently, geography and environmental sciences in Nigeria is experiencing a major transformation in terms of access, equity, and quality which is highly influenced by the integration of ICTs. In other words, the introduction of ICTs into the discipline has serious implications especially in dealing with the key issues of access, equity, management, efficiency, pedagogy and quality. The optimal utilization of opportunity arising from the integration of ICTs presents a serious challenge to the discipline of geography and environmental sciences especially in the areas of data collection, management and analysis. The concern of this paper, therefore, is the ways in which ICTs is integrated into the discipline, the attendant prospects, and the challenges posed by the integration. Literature search of information from articles from Google scholar, academia, libraries, etc. coupled with personal survey research using telephone interview are the major sources of information. Results reveal, that the field of study is experiencing a serious threat in spite of the introduction of ICTs. This results from the way in which the ICTs has been conceptualized into the field of study – ideas of positivist and empiricist science are embraced while geographical knowledge based on humanists and realist approaches to science have been neglected. However, it is suggested that especially in the area of data collection, a holistic approach should be considered. Tools that will enhance collection of data related to field of study should be developed and not just for a particular variable. Also, Government should properly fund ICTs research and provide institutions with up-to-date technologies for development and innovation, and teachers should ensure participation in training provided by institutions' management, self-enroll or access training on internet resources.

Published: January 2022

An analysis of the current traffic management system in Uyo, an urban city in Nigeria showed a heavy dependence on the use of traffic wardens. Where traffic control lights operate, they are based on fixed time allocation which often results in traffic congestion on the more operational lane and hinders the rescue work of first responders. This study proposes a traffic management system (TMS-ETD) that prioritizes the passage of Emergency vehicles over the lane with the longest waiting Time, and lastly the lane with highest traffic Density. The Dynamic Systems Development Method (DSDM) guided this work. A testbed to demonstrate the practicability of this model was designed using HC-SR505 IR sensor to measure traffic density and send the data to PIC 16F770A microcontroller, programmed using MikroC PRO version 6.0.0, for processing. The model was simulated using Proteus 8 professional version 8.6 where results showed a smoother passage of emergency vehicles necessary to safeguard lives and properties.

The essence of Entrepreneurship is making decisions that are constantly required to evaluate alternatives and make decisions regarding a wide range of matters. Decision making involves a lot of uncertainty and risk which poses serious challenges for Entrepreneurs to joggle among them in other to take the best decision. Study have shown that focus has been mainly on the analysis of the characteristics of potential entrepreneurs and the firm-creation process leaving the critical incredient that will help in decision making. The increasing challenges and complexity of business environments are making business decisions and operations more difficult for entrepreneurs to predict the outcomes of these processes. Hence, this paper proposes a decision support model -Fuzzy Inference System- that could be adapted for various business decision processes. This system has the capability to handle decision making, by critically considering the degree of membership of all the risk involved in a given problem space. The model uses the concept of fuzzy set theory to judiciously select the variables in a given problem space in an uncertain situations. From a real life practical point of view, this theory offers a natural approach to the resolution of multidimensional and complex problems when the available information is sparse and/or of poor quality. The fuzzy rule base sytem soften the adverse effects that a business may suffer from these uncertain factors. Keywords: Fuzzy logic, Membership functions, Decision, Fuzzy Set, Entrepreneur

This study aims to analyze the metacognitive skills of students with reflective-impulsive cognitive style in solving geometry problems. This type of research uses descriptive qualitative methods. Data collection techniques used instruments in the form of a Metacognitive Awareness Inventory (MAI) questionnaire, a written test in the form of geometry questions in the form of a validated essay and interviews were conducted to obtain in-depth data. Subjects were selected using a purposive sampling technique based on the results of the MAI questionnaire filling test. The results showed that students who have high metacognitive awareness are able to perform the stages of metacognition skills in problem solving and tend to have a reflective-impulsive cognitive style. Students with reflective cognitive style are able to and through all stages of metacognitive skill processes in problem solving from the planning, monitoring and evaluating stages more thoroughly and in detail, requiring a long time to solve problems but the results obtained tend to be true or accurate and can perform and regulate cognitive activities and be aware of the metacognitive activities carried out. Meanwhile, students with an impulsive cognitive style perform the problem-solving stages of the planning, monitoring and evaluating stages, which seem rushed and tend to be less thorough. Students who have an impulsive cognitive style can perform the stages of metacognitive skills in problem solving but have not been able to manage all cognitive activities and are not aware of the metacognitive activities carried out.

Kiertotalous-sanan tunnettuus ja merkitystulkinnat
Authors: Sjöblom Paula , Virsu Ville
Published: January 2022

Kestävä kiertotalous on talousmalli, jonka avulla voidaan hillitä luonnonvarojen ylikulutusta, torjua ilmastonmuutosta ja luonnon köyhtymistä samalla taloutta ja työllisyyttä vahvistaen. Uuteen malliin siirtyminen vaatii ajattelutapojen muutosta ja kiertotalouden käsitteen ymmärtämistä. Kansalaisille kiertotalous ei kuitenkaan ole kovin tuttu sana.

Tutkimus selvittää kiertotalous-sanan tunnettuutta ja merkityksen päättelyä ensimmäisen vuoden opiskelijoiden keskuudessa. Kyselytutkimus tehtiin Turun ja Itä-Suomen yliopistoissa kieltenopiskelijoille ja kauppatieteiden opiskelijoille vuosina 2019 ja 2020. Artikkelissa pohditaan kiertotalouden merkityksen päättelyä yhdysosien merkitysten perusteella sekä paneudutaan kyselyvastausten episteemistä modaalisuutta ilmaiseviin aineksiin. Siinä selvitetään myös vastaajien asenteita sekä sanan tunnettuudessa tapahtuneita kvantitatiivisia muutoksia.

Kiertotalous-sanan tunnettuus lisääntyi tutkimusjaksolla selvästi ja vastausten varmuusaste nousi, mutta epävarmuutta ilmaisevia modaalisuuden keinoja käytetään kummassakin osatutkimuksessa runsaasti. Vastauksissa käytetyt evidentiaalisuuden ilmaukset viittaavat yleensä omaan päättelyyn. Yhdyssanan edusosan talous perusteella merkitys liitetään ’talouselämään’ tai ’talousjärjestelmään’, mutta usein myös ’rahavaroihin’. Määriteosa kierto täsmentää tulkinnat useimmiten kiertää-verbin merkityksen ’vaihtaa omistajaa’ tai ’kulkea kehää’ mutta myös ’kaihtaa, välttää’ -merkityksen pohjalta.

It is an honor and privilege to accept the invitation to be the founding resident ambassador for the Journal of Diagnostics and Treatment of Maxillofacial Pathology (JDTOMP), also known as DT Journal. I am excited to join an outstanding and diverse editorial board. In this new role, I aim to engage and recruit a diverse group of oral and maxillofacial surgery trainees from the United States and abroad to launch regular evidence-based discussions regarding the current therapies for maxillofacial pathology and advancements in oral and maxillofacial surgery. I hope to eventually create a board of resident advisors that will not only serve to promote DT Journal’s presence on social media, but also as peer reviewers. The requirements for the future of the program and its incoming resident members will include the following:
1. Promotion of and sharing of issues published by the journal on social media outlets (i.e.., Instagram, Facebook, LinkedIn) using #dtjournalorg and #jdtomp.
2. Creating and sharing posts on one’s social media page as it relates to DT Journal using #dtjournalorg and #jdtomp.
3. Contributing to the journal by submitting an article of choice for peer review within two years of becoming a member.
4. Serve as a peer reviewer.
All in all, as an inaugural program for the DT journal, the resident member requirements will remain dynamic and subject to change in accordance with the Editorial Board’s missions and goals.
Similar Evolutionary Steps: Journal of American College of Surgeons and Journal of Diagnostics and Treatment of Oral and Maxillofacial Pathology
Authors: Fesenko Ievgen
Published: January 2022

The Journal of American College of Surgeons (JACS) is a highly prestigious monthly peer-reviewed publication devoted to all aspects of surgery. As of January 28, 2022 the JACS is number 10 among 456 journals in subject area “Medicine” category “Surgery.” The 2020 Impact Factor of JACS is 6.113.
The JACS, which has 117 years of traditions of print issues publishing, from January 2022 became a digital-only publication. Such transition is another step of the journal evolution in a dynamically changing academic world. Moreover, in one year the JACS implemented two transitions―the change of publisher and movement to digital-only publication.
We recognize five different forms of journal’s evolution/transition: (1) language transition (from native to English), (2) title transition (from longer to shorter one, changing journal’s scope, etc.), (3) publisher transition, (4) publishing format transition (from print-and-online to digital-only), (5) transition from subscription to open access model, etc.

Published: January 2022

This paper discusses civic participation with reference to fishing communities in the Azores archipelago, Portugal. We explore how concepts and political processes actively exclude people, and how researchers could dig deeper to find opportunities to build from diverse cultural practices of participation. Specifically, we describe examples of efforts towards participatory sustainable development as well as introduce a centuries-old highly participatory practice of sharing food. The rituals of the Cult of the Holy Spirit, based on sharing and justice, are an example of strong civic engagement rich with possibility from which to build alternatives to current forms of participation for fisheries governance. We suggest that islands offer understandings of human social interactions in ways that larger landmasses might not. This is a call for reflection on images underlying our understandings of participation and governing the sea commons, and looking more closely at islanders and their long held practices.
The research management profession within universities in small island states
Authors: Bonnici Christian , Cassar Vincent
Published: January 2022

The past fifty years have witnessed a widespread increase in the study of small states, including island studies; and the rise of the research management profession and its associated literature. Within a small island state context, the profession cannot be taken for granted, owing to smallness and other inherent characteristics of small island states. These characteristics may potentially re-shape the profession in a unique fashion and may influence the manner in which the roles of university research managers and administrators evolve in a small island state. So far, studies investigating the profession in the context of islands and small states have been lacking. This paper aims to instigate a discussion that hopefully inspires further studies about how the research manager’s role and profession may be re-shaped within small island states.
Changing politics, economics and relations on the small remote island of Fair Isle
Authors: W. Butler Richard
Published: January 2022

The paper interprets changes which have taken place on Fair Isle, a small remote Scottish island, over the last half century, with a focus on how the interplay of external forces and local adjustments have produced a positive working relationship between local residents, visitors and those in authority over the island. The paper discusses the changes in the island’s governance and economy that the island residents have experienced and how life on the island has adjusted to major change over a fifty year period. The information and responses from resident surveys discussed were collected using identical household surveys conducted fifty years apart to provide a unique comparison on a longitudinal basis of changes in the economy and way of life on the island, including the emergence of tourism as the major driver of the economy This has taken place without the common antagonism or problems between residents and visitors in tourist destinations, reflecting the appropriate handling of mutual interests and concerns through political arrangements which have been supportive and sympathetic to residents and visitors.
Governance and Cadre Deployment in South Africa

Published: January 2022

The former Minister of Cooperative Governance and Traditional Affairs, Dr Zweli Mkhize, painted a bleak picture about the state of local government. The minister stated that 87 municipalities – about a third of South Africa’s total of 257 – remain dysfunctional or distressed. Underpinning this dysfunctionality was mismanagement due to political instability or interference, corruption and incompetence. This then results in poor service delivery, thus prolonging the periods of underdevelopment and poor access to basic services. This paper argues that cadre deployment has hindered the effective service delivery in local municipalities, thus the domino effect has been riots, protests and wasteful expenditure at the local government level. This results in participatory exclusion when it comes to collective development.  By strictly analysing relevant literature related to corruption, and cadre deployment within the local government domain in South Africa, it became evident that the quest for socio-economic development in rural areas is deeply dependent on local governance having competent and skilled personnel who would prioritise service delivery rather than political loyalty at the expense of development. Nonetheless, the main question going forward is to what extent will loyalty ahead of competence be at the core of municipal governance and what implications will this have for future developmental prospects, good governance and service delivery?

Scientists have lately discovered that the quality of services has a significant influence on academic satisfaction and academic loyalty. Universities in Erbil are competing attract academics by conducting international conferences. The purpose of this study is to evaluate the service quality in international conferences. A statistical analysis was provided based on data collected from 150 responses from academics at Cihan University-Erbil and other universities in the region. A structured questionnaire was conducted by the respondents in order to analyze their general expectations on conference services and the actual service performance they perceived with the conference. The study also assessed the impact of respondents’ past experiences on their expectations. The findings of this study show that we have positive effect between the total effect of (SQ) the independent variable on (CI) the dependent variable is highly significant with (t = 6.02, p< 0.05), also the effect of the mediator variable (AS) was significant with (t = 7.01, p< 0.05), and finally both the independent variable and the mediator variable (SQ) and (AS) have a significant effect on the dependent variable (CI). We found that the meditation effect was partial but not complete effect.

It is clear that the COVID-19 virus has affected human life and activities all over the world. The agricultural sector is not excluded from the affection of course. The importance of this issue encouraged us to carry out this statistical study aiming to show the impact of COVID-19 on the agricultural supply chain (Vegetative) production in Halabja. Three forms of the self-administered questionnaire (SAQ) were used to collect data from three targets; farmers, wholesalers, and retailers using the nonprobability sampling method. Descriptive analysis was used to show frequencies, percentages, and mean scores, while Independent Sample T-Test was used to find the relationship between variables using SPSS software V.26. Results show that there is no statistically significant relationship between characteristics of production and residence. Lockdown had a major impact on the plant production and its supplying chain in the following sequence: fewer products were delivered to the wholesaling markets by farmers, retailers bought less so consumers got fewer products.
GROUPING OF M3 LINES OF LOCAL TIDAL SWAMP RICE VARIETIES OF SOUTH KALIMANTAN BASED ON AMYLOSE AND AMYLOPECTIN CONTENT
Authors: Ellya Hikma , Wahdah Raihani
Published: January 2022

The creation of new superior rice varieties with high productivity and short-lived is necessary to support food security. The rice varieties produced must also meet people’s preferences, in this case have a rice taste that is preferred by the people of South Kalimantan. The purpose of study was to determine differences in content of amylose and amylopectin of rice grains between the genetic material, which consists of mutant lines of M3 and five parents of local varieties of South Kalimantan. The experiment used a randomized block design with two replications, the genetic material as single faktor, used being five local varieties of South Kalimantan and 25 M3 mutants derived from each parent’s mutation. The data was analyzed of variants with the F test at the level of α=5%, then continued the Scott-Knott test at α=5%. The results showed that content of amylose and amylopectin of grain of M3 lines significantly different with each parent. The results showed that the amylose and amylopectin content of rice grains from 30 genetic materials was significantly different. The results of the analysis of the grouping of 25 mutant lines and five parent varieties based on the content of amylose and amylopectin were obtained by nine groups. There are seven groups that belong to the rice type of rice textured pera consisting of 19 M3 lines and five parents. There are two groups that belong to the pulen textured rice group consisting of six M3 lines.

WeRise is a rainfed specific technology (IRRI-JIRCAS-IAARD) that helps farmers to determine planting time according to rainfall distribution and specific variety. The research was conducted in West Nusa Tenggara (WNT) and Central Java at 2018, involving 15 farmers in each location. It compared planting time according to WeRise’s recommendation (1) and farmers’ practice (2), using the same variety, namely Inpari 41, which is a specific high yielding variety for rainfed. It was analyzed using the T test at the 5% level. The best WeRise’s recommendations in WNT was ± 1 December 2018, while farmers’ planting time was carried out on ± 15 November 2018. Meanwhile, in Central Java WeRise’s recommendations was same as the farmers, on ± 15 November 2018. However, testing was still carried out following the second / third alternative WeRise recommendation even though the yield prediction were lower (1 December 2018). The yield from WeRise treatment and farmer practices was not significantly different with an average yield of 5.01 t ha-1 for the WeRise treatment and 4.84 t ha-1 for farmer practice in Central Java and an average yield of 5.44 t ha-1 for the WeRise treatment and 5.65 t ha-1 for farmer practice in WNT. This means that in this initial validation WeRise had shown a fairly good performance with equivalent yield to farmers. However, it was suspected that Werise’s prediction in Central Java was still too low or 54% lower than the actual yield, while the prediction in NTB reaches 102%.

Potassium is one of the primary macro nutrients along with N and P nutrients, which plants need in large quantities. Lack of K nutrients, one of which can inhibit photosynthetic transport to plant seeds. The availability of K nutrients in paddy soil varies greatly depending on the chemical properties of other soils. This paper aims to evaluate the nutrient K characteristics of paddy fields, the K contribution from irrigation water and harvested straw, and the response of fertilization to rice yields. The availability of K nutrients, apart from being influenced by clay mineral composition, clay content, organic C and soil CEC, is also influenced by N fertilization, soil pH, exchangeable of Ca and Mg, and N-total. The content of potential K and exchangeable of K increases in paddy fields which are further east of Java Island because they have soil with parent material that is rich in potassium minerals. The content of exchangeable K is very closely related to the potential K with R2 = 0.53 (n = 73). Based on the map of the nutrient status of K rice fields with a scale of 1:250,000 in 23 provinces in Indonesia, it is known that most of the paddy fields have moderate K status at 37% and high 48%. The K content in paddy soil can be contributed by irrigation water as much as 7-74 kg K/ha/season. If all of the remaining rice straw from crop yields is returned to the field, the K nutrient requirements for rice plants in the medium and high K nutrient status fields have been fulfilled. The response to K fertilization in rice plants was only visible when the exchangeable K content < 0.10 cmol(+)/ kg. The policy implication of this paper is that K fertilization is focused on paddy fields with low K content, the effectiveness of K fertilization can be increased by returning rice straw from crop residues and proper N fertilization.
