Published: November 2021

Sasirangan is a traditional fabric typical of the Banjar tribal community and has now been developed into an industrial product in Banjarmasin. Sasirangan's business development shows a significant development and it becomes very essential to pay attention to how to maintain its business. This article aims to describe the business operations and distribution patterns in the Sasirangan clothing industry. The qualitative approach was used in this study coupled with data collection through interviews, observations, and documentation. The results showed that Sasirangan fabric products are produced by artisans who work individually or in groups and marketed by traders. Marketing of Sasirangan cloth products uses a direct distribution pattern to consumers, and indirectly uses a merchant intermediary who then resell them to consumers. The collaboration of Sasirangan artisan and traders can be further enhanced to develop a convection industry based on local culture. The findings of this study provide a further description of how local culture-based businesses require support from the government and other parties to maintain business sustainability.JEL Classification J24; M31; O14

Authors: Kristianto Aloysius Hari , Widya Pramatatya Resindra , Nadapdap Jones Parlindungan 
Published: November 2021

Underground economic activity is a phenomenon that requires special and continuous treatment. This phenomenon is counterproductive to local revenues and is related to corrupt practices and tax evasion. The research was conducted in Bengkayang Regency, West Kalimantan Province, Indonesia. The qualitative phenomenological method was carried out by interviewing underground economic actors such as liquor producers, "pangku" coffee shops, and street vendors. The findings indicate that corruption activities in the form of collecting bribes and offering bribes are carried out in cash without going through a legal transaction mechanism. The underground economy practices tax evasion, does business without a permit, pays substandard wages, and does not protect workers with insurance. The underground economic activity will contribute to an increase in the circulation of money in society, but do not take into account the regional economy. Such situations call for massive supervision of individuals and the introduction of pentahelix elements to form synergies between actors and to begin to integrate and develop digital structures in every financial activity using e-government systems.JEL Classification D73; E26; O17

Published: November 2021

Poverty is a multidimensional phenomenon that causes difficulty for people to meet their needs. The research aims to scrutinize physical and social infrastructures concerning multidimensional poverty levels using the spatial approach. Jabung District, Malang Regency, Indonesia has 35% poor households in this case study. The objectives are to measure multidimensional poverty levels, social capital indices of the rate of participation (RoP) and density, and scrutinize neighborhood relationships among 15 villages using spatial regression analysis. Data collection is through a questionnaire survey of 274 heads of households. The research identified four poverty levels (very low to high), where five villages with high poverty levels (Jabung, Taji, Kemiri, Gunungjati, Slamparejo) became the targeted areas. The majority of the villages had a medium level of both the RoP and density, and the community had moderate social relations among community members. The spatial regression analysis indicates that the attribute of the RoP and weight matrix have a significant impact on the poverty level. It is recommended that poverty alleviation programs should focus upon the cluster of poor villages through social infrastructure development as the action to end poverty.JEL Classification A13; I32; R58

Increasing production from rainfed rice field farming is expected to have direct implications to farmers’ income and food security. Improvement in farmers’ income will ensure the fullfillment of quality food. This study aims to analyze the contribution of rainfed rice farming to the household income and household food security of the farmers who cultivate rice in rainfed rice fields. This research was conducted in Maros Regency in three districts, namely Lau, Maros Baru and Simbang. The sample of this research was 100 farmers in rainfed rice fields. The research used survey method with the instruments of observation, recording and interviews. Data were analyzed using quantitative description coupled with t-test for independent samples. The results showed that the rainfed rice farming contribution to the household income in Lau, Maros Baru and Simbang District was 90.0%, 70.0%, and 57.5%, respectively. In term of farm household food security based on the share of food expenditure, the farmers’ households were food insecure with 73.33%, 83.33%, and 67.50% for each regions. This study suggests that farmers need to diversify their income source to crops other than rice. Such effort will be able to increase the income and food security of farmers’ households.JEL Classification Q12; Q18; R14

Published: November 2021

Indonesia imports fruits from around the world to serve people’s demand. Thailand as one of the fruit exporters to Indonesia needs to further explore what influences the consumption of Thai Fruits in Indonesia. Moreover, currently the COVID-19 pandemic likely affects all sectors, including the agriculture sector. This study aims to analyze the relation between socioeconomic characteristics and consumer behavior, particularly the pandemic period, that affects the purchasing decision of Thai Fruits. Using a structured questionnaire, random sampling of 1,736 respondents who shop at 5 All Fresh Supermarket branches were interviewed. The data was analyzed using the chi square test and binary logistic regression. The results found that socioeconomic characteristics such as age, gender, education, occupation, and income had a relation with Thai Fruits purchasing decision. In term of product awareness for instance, quality and taste is the utmost concern for customers. However, during COVID-19 pandemic, the level of customers’ consideration for quality and safety is clearly higher. Therefore, a different strategy is needed to convince consumers. The result also found that tasting experience influences purchasing decision significantly. To enhance international economic development, such agricultural products must respond to the customers’ needs and mutual cooperation between trading countries.JEL Classification: F13; Q13; Q17

Relevance. Miscarriage is one of the most common obstetric pathologies that determine the spontaneous death of the fetus. The role of changes in the microbiome of various biotopes is considered as a risk factor of this disease.Aim of the research is to assess the microbiocenoses structure of the reproductive system and the intestine associated with the development of spontaneous miscarriages in early pregnancy.Materials and methods. A case-control study was conducted and organized. The group of «cases» included 23 women with spontaneous miscarriage at 5–14 weeks of pregnancy and the control group included 23 women with normal pregnancies Based on the data of metagenomic sequencing of V3–V4 regions of the 16S rRNA gene, a comparative assessment of the structure of the vaginal and intestinal microbiome in these groups was carried out.Results. As a result of the study, a number of taxonomic groups of microorganisms in the vagina and intestines associated with miscarriage. It was found that the decrease in the proportion of Lactobacillus spp. in the structure of the vaginal microbiome, less than 90% of the total number of identified taxa is associated with this pathology (OR = 5.28 (95% CI = 1.2-23.2)). The gut microbiocenoses of women with spontaneous miscarriage are characterized by less taxonomic diversity than the gut microbiome of women with advanced pregnancy. At the same time, some representatives of the intestinal microbiome (Akkermansia sp., Faecalibacterium sp., Bifidobacterium sp., Methanobrevibacter sp., Lactococcus sp.) predominate in women with a normal pregnancy.Conclusion. The study demonstrated a significant role of changes in microbiocinosis of the reproductive tract and intestines in miscarriage. There is a potentially protective function of lactobacilli. The obtained data substantiates the need for active use of molecular genetic methods focused on the assessing the structure of the vaginal and intestinal microbiota in assessing the risks of reproductive failures.

Published: November 2021

Relevance. Whooping cough remains a pressing public health problem worldwide, including in countries with high vaccination rates. One of the probable causes of the ongoing epidemic process of pertussis infection is B. pertussis biofilms, which differ from plankton cultures by an altered gene expression spectrum and are highly resistant to environmental conditions, antibiotics, and immune factors.Aims. Analysis of literature data on the genetic and molecular - cellular mechanisms of biofilm formation by bacteria of the genus Bordetella, as well as approaches to the search for means aimed at suppressing the growth of biofilms and the destruction of formed biofilms in the macroorganism.Conclusions. Biofilm formation by microbes of the genus Bordetella is a complex multistage process regulated by genetic signaling systems: the Bvg AS system and the 2-nucleotide (p) ppGrp system, as well as other regulatory proteins and the polysaccharide complex. The matrix of B. pertussis biofilms consists of extracellular DNA, proteins, and a polysaccharide polymer that play an important role in the formation of biofilms in the respiratory tract and on abiotic surfaces. The genetic and molecular-cellular processes of biofilm formation and maintenance, as well as the various components of the biofilm matrix, can serve as targets for new antimicrobial drugs and more effective pertussis vaccines that will better control the entire pertussis infection cycle, including colonization, persistence, and transmission of the causative agent. One of the approaches to the development of new-generation cell-free pertussis vaccines is the identification of new biofilm-associated antigens that can induce effective cellular and humoral responses. The search for drugs that can destroy biofilms, including substances that affect the matrix and facilitate the access of antibacterial drugs to microbial cells, is promising.

Published: November 2021

Relevance. The success of the global community in the fight against measles through vaccination at the beginning of the twentyfirst century allowed WHO to declare the goal of eliminating this infection by 2010. However, ten years later, the problem of the growing incidence of measles has become relevant again for all countries of the world. The pandemic of the new coronavirus infection (COVID-19) has affected all spheres of human life and has exacerbated the situation in the fight against other infections, including those managed with the help of specific prophylaxis. Since the measles contagiosity index and mortality rate are significantly higher than similar characteristics of COVID-19, the risk of increasing the incidence of this infection in the coming years is difficult to overestimate.Aim of the study: to assess the epidemic situation of measles in the context of the COVID-19 pandemic, as well as the prospects for its development; to propose preventive measures.Materials and methods. The article analyzes the statistical materials available on the official websites of the WHO (WHO). https://www.who.int/data/), the CDC US (https://www. cdc.gov) and the Federal Service of Rospotrebnadzor (https://www.rospotrebnadzor.ru/) on vaccination coverage and measles incidence in 13 countries in the WHO European Region and the United States. The epidemic situation on measles, as well as the level of population coverage with vaccination against its pathogen in the Russian Federation, were assessed according to the Federal State Statistical Observation forms 2010 – 2020: Form 2 «Information on infectious and parasitic diseases» and Form 6 «Information on the populations of children and adults vaccinated against infectious diseases».Results. It has been established that the increase in the measles incidence occurred in 2017–2019 worldwide, including European countries with a population coverage of two vaccine doses at the 97% level between 2010 and 2019. The prevalence of measles cases in children under the age of 10 is shown, as well as the wide range (from 56.9% to 10.9%) in the proportion of vaccinated persons among them. The results obtained indicate the existence of problems in the organization of modern vaccine prevention. The introduction of widespread restrictive and quarantine measures against the COVID-19 pandemic, on the one hand, has reduced the incidence of measles and, on the other hand, has exacerbated the difficulties in implementing measles prevention. Thus, the results indicate a possible increase in measles incidence in the population after the end of the COVID-19 pandemic.Conclusion. It is necessary to immediately develop an action plan to catch up on the coverage and increase the rate of routine vaccination, to improve the statistical record of persons subject to the introduction of the vaccine and vaccinated, as well as to overcome anti-vaccination attitude among the population.
