Abstract

Propagation of jasmine plants by cuttings often experience obstacles, especially to grow roots. Proper planting media and application of growth regulators (PGR) have an important role in the growth and development of plant cuttings roots. The purpose of this study was to determine the effect of planting media types and PGR on the growth of jasmine cuttings. This research was conducted in the experimental garden of the Faculty of Agriculture, Teuku Umar University, in March - May 2019. This study used a completely randomized design (CRD) with a factorial pattern of 3x3 with three replications. The treatment factors studied were (1) the type of planting media consisted of 3 levels namely alluvial soil, sand and husk charcoal, and (2) the type of growth regulator (ZPT) consisted of 3 levels namely control (without zpt), chemical (growtone) and organic (shallot extract). F test results on the analysis of variance showed that the planting medium had a very significant effect on the number of shoots 35 and 45 HST, number of leaves 15, 35 and 45 HST number of roots, root length, percentage of live cuttings. But the planting media had no significant effect on the number of shoots of 15 DAP. Growth regulator substances have a very significant effect on the number of shoots 35 HST, number of leaves 15, 35 and 45 HST, number of roots and root length. Significantly affect the number of shoots 45 HST and percentage of live cuttings, but no significant effect on the number of shoots 15 HST. This shows that the difference in growth of jasmine plant cuttings due to different planting media does not depend on growth regulators, and vice versa.

Abstract

The ethno- medicinal and conservation status of indigenous vegetables in Akinyele Local Government Area (LGA) of Oyo State, Nigeria were examined with a view to evolving strategies that will conserve them. A combination of social surveys and direct field observations was used. Farm and market surveys were conducted. Five farm settlements and three major markets were used. 10 each of farmers and vegetable vendors were randomly selected and interviewed with aid of semi-structured questionnaire matrix to obtain information on the vegetables in the farms and those sold in the markets. Results obtained suggested the existence of gender specificity in agricultural activities in the study area. Women were responsible for the cultivation, harvest and haulage of vegetables. A total of 33 vegetables belonging to 18 families were identified in the study area. 21 were sampled in farm settlements and markets, 11 in farm settlements only and 1 in market only. Not all the identified vegetables have been utilized as source of income. The family Amaranthaceae has the highest number of species and their ecological success may be attributed to the fact that they are mostly herbs, a few shrubs, under-shrubs, annual or perennial with efficient tap root system and adaptation to varieties of soil. The vegetables were sourced from diverse habits including herbs, shrub and trees. The leaf constituted the major part used for vegetables. All identified vegetables were rich in phytochemicals and used to manage an array of diseases. Strategies that could enhance continuous supply of the vegetables were proposed.

Abstract

Trans-sectoral digital research of man, nature, society and industrial communication allows to create digital twins of social services. Digital duplicates associated with the service sector are created for intelligent process management. Digital twins of man provide services in the social sphere and in space. Training of digital twins in professional competences is carried out on the basis of communicative associative logic of technological thinking by cognitive methods. The study of the effectiveness of machine learning techniques, allowed the use of an approach that allows the combination of artificial intelligence and cognitive psychology. This approach provided pre-preparation of neural networks from accumulated data using existing behaviors. The approach combines existing scientific theories of human behavior with the flexibility of neural networks to make better decisions made by humans in space and in extreme situations. From a practical point of view, this makes it possible to more accurately determine the behavior of the human digital twin in space and in extreme situations. There are a number of socio-economic issues related to human-machine interaction. Complex technologies are not credible on the part of citizens. The coming years will take to improve safety and standardize the creation, application of digital twins and behavior of robots.

Abstract

Pregnancy control and regulation is one of the ways to suppress the population in Indonesia through the family planning (KB) program. However, family planning programs in Indonesia still have problems, one of which is the high number of unmet need for family planning in Indonesia. 5 sub-districts in the City of Binjai showed that the District of Binjai Kota which had the highest number of unmet need for family planning was 18.27%. The purpose of this study was to analyze the Relationship of Education, Number of Children and Acceptance of Family Planning Information with Pregnancy Due to Unmet Need for KB in Pregnant Women in Binjai City Health Center in 2019. The method of this study used a cross sectional sample of 113 pregnant women in December 2018 - August 2019 at the Binjai City Health Center. Data were collected by interview using a questionnaire. Based on the results of the study note that out of 113 pregnant women there were 57 people (50.4%) who became pregnant as a result of Unmet Need KB. Variables related to Pregnancy Due to Unmet Need for KB are the number of children (p = 0.024) and the receipt of KB information (p = 0.001). The results of multiple logistic regression showed that respondents who had 1-2 children and did not receive family planning information had a probability of suffering from pregnancy due to unmet need for birth control by 57.8%. The suggestion for this research is that health workers pay more attention to those who have 1-2 children who are motivated to participate in the family planning program and ask pregnant women to ask health workers before using family planning tools as clearly as possible so that they are expected to be able to reduce the reasons for unmet need for family planning.

Abstract

A rapid appraisal technique was used to survey fruit trees species in Ifaki-Ekiti, an urban community in Ekiti State, Nigeria. The three major routes in the town and three educational institutions were sampled. Fruit trees within each stratum were identified to species level, counted and recorded. Similarity indices and indices of diversity in the occurrences of the species were determined among the strata. The perceptions of residents on the fruit trees were also determined through the use of a semi- structured questionnaire matrix administered on 20 randomly selected individuals in each of the stratum. Respondents’ indigenous knowledge on the species were determined and recorded. 96 fruit trees individuals belonging to 9 species and 6 families were sampled. The family Anacardiaceae has the highest number of species. The most frequently occurring species along the routes were Carica papaya, Anacardium occidentale, and Citrus sinensis with 12,10 and 8 individuals respectively and for the educational institutions were Anacardium occidentale, Mangifera indica and Carica papaya with 26,17 and 8 individuals respectively. 87% of the respondents were familiar with the cultivation of fruit trees and 67% of respondents were involved in planting of fruit trees in their household environment. Preference was skewed towards planting of fruit trees as food, source of vitamins and source of income. Strategies that could improve fruit tree diversity in the study area were proposed.

Abstract

This research evaluated climate change impacts on temperature, precipitation, and runoff using LARS-WG and SWAT models under climate scenarios. First, drought intensity was calculated for the period 1987-2016. Then, the LARS-WG model was calibrated to generate climatological data for future periods. The coefficients of precipitation as well as minimum and maximum temperature changes were simulated as SWAT model inputs. The results of LARS-WG model indicated that temperature will increase in future periods and that changes will occur not only in precipitation rate but also in its pattern. Then, changes in runoff were simulated by introducing downscaled results to SWAT model. The model was calibrated and validated by SWAT-CUP software. Nash-Sutcliffe (NS) coefficients (0.58 and 0.49) and R2 determination coefficients (0.65 and 0.50) were obtained for calibration and validation periods, respectively. The results showed that runoff will increase in spring and summer during 2011-2030 period, but it will decrease in fall and winter. Further, runoff will rise in fall and winter while it will drop in spring and summer throughout 2046-2065 and 2080-2099 periods under all three scenarios. Such seasonal shifts in runoff levels result from climate change consequences in the forms of temperature rise, snowmelt, altered precipitation pattern, etc. Future-period evapotranspiration will rise under all three scenarios with a maximum increase in 2080-2099 period under A2 scenario. Additionally, rainfed crop yields will decline without considerable changes in irrigated and horticultural crop yields.
