Authors: Oktaviani Rina , Ikawati Zullies , Yasin Nanang Munif
Published: December 2021

Background: Diabetic ketoacidosis (DKA) is a life-threatening complication of acute diabetes mellitus (DM). Insulin is one of the therapies for DKA, which can reduce potassium levels by shifting potassium from extracellular to intracellular. Consequently, early administration of potassium is important in the resolution of DKA. Objective: To determine the correlation between potassium administration and resolution in patients with DKA and the factors affecting such resolution. Methods: An observational study was employed with a retrospective cohort design for inpatients with a diagnosis of DKA during the period of January 2015-August 2020 at Dr. Sardjito Hospital Yogyakarta. Appraisal of the resolution of DKA variable was based on the achievement of blood glucose targets, followed by 2 criteria of serum bicarbonate, pH, and anion gap during 24 hours of therapy. This study involved 55 patients divided into groups with potassium administration and without potassium administration. Data were analyzed using the chi-square test and multivariate logistic regression. Results: The resolution of DKA achieved in less than equal to 24 hours in the group with potassium was 48.5% (16 patients) while it was 18.2% (4 patients) without potassium. Based on the chi-square analysis, there was a relationship between potassium administration and the resolution of DKA (p=0.045; RR=2.667; 95%CI=1.028-6.920). The multivariate analysis showed that the severity and history of DM were positively related to the resolution of DKA (p=0.025; OR: 8.901; 95%CI=1.318-60.123 and p=0.017; OR: 0.090; 95%CI=0.012-0.652). Conclusion: Potassium administration resulted in 48.5% of the DKA patients achieving a resolution in less than equal to 24 hours from the commencement of DKA therapy. The severity and history of DM became the factors that affected the resolution of DKA. Keywords: diabetic ketoacidosis, potassium, resolution
ESTIMATING WITH A GIVEN ACCURACY OF THE COEFFICIENTS AT NONLINEAR TERMS OF UNIVARIATE POLYNOMIAL REGRESSION USING A SMALL NUMBER OF TESTS IN AN ARBITRARY LIMITED ACTIVE EXPERIMENT
Authors: Pavlov Alexander
Published: December 2021

We substantiate the structure of the efficient numerical axis segment an active experiment on which allows finding estimates of the coefficients fornonlinear terms of univariate polynomial regression with high accuracy using normalized orthogonal Forsyth polynomials with a sufficiently smallnumber of experiments. For the case when an active experiment can be executed on a numerical axis segment that does not satisfy these conditions, wesubstantiate the possibility of conducting a virtual active experiment on an efficient interval of the numerical axis. According to the results of the experiment, we find estimates for nonlinear terms of the univariate polynomial regression under research as a solution of a linear equalities system withan upper non-degenerate triangular matrix of constraints. Thus, to solve the problem of estimating the coefficients for nonlinear terms of univariatepolynomial regression, it is necessary to choose an efficient interval of the numerical axis, set the minimum required number of values of the scalarvariable which belong to this segment and guarantee a given value of the variance of estimates for nonlinear terms of univariate polynomial regressionusing normalized orthogonal polynomials of Forsythe. Next, it is necessary to find with sufficient accuracy all the coefficients of the normalized orthogonal polynomials of Forsythe for the given values of the scalar variable. The resulting set of normalized orthogonal polynomials of Forsythe allows us to estimate with a given accuracy the coefficients of nonlinear terms of univariate polynomial regression in an arbitrary limited active experiment: the range of the scalar variable values can be an arbitrary segment of the numerical axis. We propose to find an estimate of the constant and ofthe coefficient at the linear term of univariate polynomial regression by solving the linear univariate regression problem using ordinary least squaresmethod in active experiment conditions. Author and his students shown in previous publications that the estimation of the coefficients for nonlinearterms of multivariate polynomial regression is reduced to the sequential construction of univariate regressions and the solution of the correspondingsystems of linear equalities. Thus, the results of the paper qualitatively increase the efficiency of finding estimates of the coefficients for nonlinearterms of multivariate polynomial regression given by a redundant representation.

Published: December 2021

Currently, the question of state, formation and development of the information source interaction system, the scientific interaction and users' requestsin certain fields of activity remains relevant under the conditions of the development of the use of Internet services. Recommendation systems are oneof the types of artificial intelligence technologies for predicting parameters and capabilities.Due to the rapid increase in data on the Internet, it is becoming more difficult to find something really useful. And the recommendations offered by theservice itself may not always correspond to the user's preferences. The relevance of the topic is to develop a personal recommendation system forsearching books, which will not only reduce time and amount of unnecessary information, but also meet the user's preferences based on the analysis oftheir assessments and be able to provide the necessary information at the right time. All this makes resources based on referral mechanisms attractiveto the user. Such a system of recommendations will be of interest to producers and sellers of books, because it is an opportunity to provide personalrecommendations to customers according to their preferences.The paper considers algorithms for providing recommender systems (collaborative and content filtering systems) and their disadvantages.Combinations of these algorithms using a hybrid algorithm are also described. It is proposed to use a method that combines several hybrids in onesystem and consists of two elements: switching and feature strengthening. This made it possible to avoid problems arising from the use of each of thealgorithms separately.A literature web application was developed using Python using the Django and Bootstrap frameworks, as well as SQLite databases, and a system ofrecommendations was implemented to provide the most accurate suggestion. During the testing of the developed software, the work of the literatureservice was checked, which calculates personal recommendations for users using the method of hybrid filtering. The recommendation system wastested successfully and showed high efficiency.

Published: December 2021

The problem and the main stages of choosing a rational configuration of a four-level logistics network that is resistant to the impact of emergencies forstrategic planning are considered. The problem under consideration belongs to the class of multicriteria optimization problems. Criteria related to thefinancial costs of building and operating a logistics distribution channel, as well as criteria related to the level of quality of customer service, arecontradictory. To solve the problem of stability of the logistics system configuration to emergencies, such as failure of intermediate warehouses,failure of transport arteries, etc., a strategic management information system was developed by integrating existing software components at the level ofenterprise software applications. The integration of the system was based on a service-oriented architecture, as all its components are heterogeneous innature. This approach allows you to reuse existing program code. To determine a sustainable configuration option, two criteria are used, which areconsidered equivalent: the level of costs for the maintenance of the logistics channel and the level of service quality in the event of differentemergencies. Since the probability of emergencies is unknown, the minimax criterion is used to minimize the risk when choosing a rationalconfiguration of the logistics network. For this purpose, losses from emergencies are calculated according to all criteria, and there is a variant of thelogistics network configuration that will be the least risky. That is, we will not be able to get a worse result than the one we rely on. The results of thestudy are presented in the form of a configuration variant of the logistics distribution system, which can be used in the future to determine businessoptions.
EXTRACTION OF ELASTIC, VISCOUS AND INERTIAL COMPONENTS FROM THE TOTAL REACTION OF AN ADDITIONAL SUPPORT ATTACHED TO A RECTANGULAR PLATE
Authors: Voropay Alexey , Yegorov Pavel
Published: December 2021

The paper deals with a mechanical system consisting of a hinged rectangular plate and an additional viscoelastic support with considering its mass-inertia. The impact of the characteristics of additional support on the plate strained state is studied by an original approach of extracting elastic, viscous and inertial components from the total reaction. The plate is assumed to be medium thickness, elastic and isotropic. The Timoshenko hypothesis is used for deformation equations. The external non-stationary force initiates plate vibrations. The impact of the additional support is replaced by the action of three unknown independent non-stationary concentrated forces. The basic formulas for deriving system of three Volterra integral equations are proposed. The system is then solved by numerical and analytical method. By discretizing in time the system of Volterra integral equations is reduced to a system of matrix equations. The system of matrix equations is solved with using generalized Kramer’s algorithm for block matrices and Tikhonov’s regularization method. Note that the approach proposed is applicable for other objects with additional supports, such as beams, plates and shells having various boundary contour and boundary supporting. The results of computing elastic, viscous and inertial components of total reactions on the plate are given. The approach proposed is verified by matching the results of computations by two different methods, namely numerical and analytical for one total reaction and numerical for the total reaction obtained by adding elastic, viscous and inertial components.

Published: December 2021

Living in a big city such as Jakarta that is densely populated and crowded is challenging. The limited open land is an obstacle for schools in urban areas, especially in the Central Jakarta region, to stimulate children's naturalistic intelligence and sometimes become a forgotten thing. The rapid progress of technology and information makes children become electronic addiction and nature deficit disorder. The teacher feels it is difficult to carry out activities related to nature.

The results of preliminary observations show that the naturalistic intelligence of early childhood still has not received attention to be developed. The lack of teacher creativity to create and design activities to improve children's naturalistic intelligence is also another obstacle. Likewise, parent involvement in children's learning activities is still not optimal.

The aims of this study was to look at the effect of hydroponic gardening activities and parents involvement on the naturalistic intelligence of early childhood. This study included an ex post facto study using a quantitative survey research approach to TK B children. The results of the studyshowed that there were hydroponic gardening activities and parental involvement had a significant influence on naturalistic intelligence in early childhood. Urban farming activities such as hydroponic gardening need to beintroduced to kindergaten teachers to get around the limited land in schools. Hydroponic gardening activities can bedesigned so parents can be involved in learning with children and teachers with a pleasant atmosphere

Authors: Oli Mario Colega
Published: December 2021

While assessment practices are very important into the students’ learning and development, the processes of assessment may follow a logical progression from the selection and development of classroom assessment to the communication of the assessment results. Teachers may have similar assessment practices but they vary on the processes in conducting the assessment. Through Delphi Technique, evaluation experts assessed the extent to which mathematics assessment practices satisfy meta-evaluation criteria of utility, feasibility, propriety, accuracy and accountability employed by Mathematics Educators of pre-professional mathematics teachers in some select State Universities in the Philippines. The assessment practices of the  Mathematics Educators were meta-evaluated with high ratings on utility,  feasibility, propriety, and accuracy, while only moderate in accountability. Assessments performed in the largest state university have better overall utility, accuracy and accountability with overall feasibility and propriety about the same level across the four state universities. Hence, the respondents should develop assessment strategies for students with different learning abilites, continuesly improve their technqiue in assessing students’ learning and have sound judgement not only through the students’ quantitative scores but the impact of feedback about their performance for future use.

Rice is the main and strategic commodity in East Kalimantan Province as primary food source. Rice production in this province was relatively low, around  66.57% of its consumption need, or at 33.43% deficit in 2019. This deficit will continue to increase if East Kalimantan becomes the country's capital city in 2025 due to arrival of new residents. Therefore, a proper policy to improve the balance of rice production and consumption need should be designed. This study aimed to develop rice availability balance model and formulate policy recommendation to fullfil the rice needs in the country's capital city candidate. The method used was dynamic system approach as rice balance availability determined by supply and demand sub-system. The study results showed that the model developed could describe the rice availability balance in East Kalimantan and had good validity level. Based on the simulation results on the existing condition in 2025, the rice availability in East Kalimantan as the country's capital city was only 44.80% of the consumption need. A recommended policy scenario to improve the rice balance in this provionce is the combination of policies on production and consumption sides, namely minimal rice planting index at 1.9 (irrigation) and 1.2 (without irrigation), minimum rice yield at 4.67 tons per ha (irrigation) and 3.50 ton per ha (without irrigation), open up new rice field  at 1,000 ha, no rice field conversion, conversion rate from unhusk paddy to rice yield at 64%, and maximum per capita rice consumption at 80 kg/year.

The purpose of this study was to test the effect of the application of vermicompost on growth, nutrient content and yield of green lettuce with different number of plants per pot. This experiment used a factorial randomized block design. The first factor was kinds of vermicompost application. The second factor was number of plant per pot. The research results showed that the application of solid vermicompost had the highest growth and nutrient uptake in plant height (22.73 cm), number of leaves (8.81) and leaf area (974.76 cm2) as well as an average of N = 4.39%, P = 0.77% and K = 9.07%. The treatments of solid+liquid vermicompost and liquid vermicompost alone, three plants per pot tend to provide the lowest nutrient uptake. However, the highest fresh weight of biomass and marketable yield was obtained in the application of solid vermicompost with three plants per pot by 122.22g and 111.77g, respectively. These results suggest that the application of solid vermicompost and three plants per pot is recommended in soilless culture for green lettuce plants.

Keputusan untuk mengadopsi varietas atau teknologi baru, terutama bagi petani skala kecil,  sangat dipengaruhi oleh kepemilikan sumber daya. Tujuan penelitian ini adalah mengevaluasi pengaruh kepemilikan aset produksi petani terhadap keputusan petani menggunakan Varietas Unggul Baru (VUB) pepaya Merah Delima. Survei dilaksanakan di beberapa sentra produksi pepaya (Sumatra Barat, Riau, Jawa Timur, Jawa Tengah, dan Jawa Barat) melibatkan 46 responden terpilih yang terdiri atas 17 petani pengguna pepaya Merah Delima dan 29 petani penanam pepaya varietas lainnya. Faktor-faktor determinan penggunaan varietas dianalisis dengan menggunakan model regresi Logit dan Tobit. Ketersediaan sarana dan prasarana produksi berpengaruh signifikan terhadap keputusan petani menggunakan VUB pepaya Merah Delima. Pengaruh sarana dan prasarana produksi terhadap  probabilitas peningkatan penggunaan varietas lebih dominan dibanding pengaruh faktor-faktor lainnya. Oleh karena itu, program pengembangan VUB pepaya Merah Delima lebih lanjut disarankan perlu didukung dengan bantuan penyediaan alat semprot (sprayer) bertenaga mesin atau ditargetkan di lokasi-lokasi yang tidak terlalu bermasalah dengan tata kelola air.

Abstract

The decision to adopt a new variety or technology, especially for small-scale farmers, is heavily influenced by resource ownership. The purpose of this study was to evaluate the effect of farmer production asset ownership on farmers’ decisions to use Merah Delima papaya high yielding variety (HYV). The survey was conducted in several papaya production centers (West Sumatra, Riau, East Java, Central Java, and West Java) involving 46 selected respondents consisting of 17 farmers using Merah Delima papaya and 29 farmers growing other papaya cultivars. The determinants of farmer decision were analyzed using the Logit and Tobit regression models. The results show that the availability of production facilities and infrastructure has significant effects on farmers’ decisions to use Merah Delima papaya HYV. The influence of production facilities and infrastructure on the probability of increasing the usage of Merah Delima papaya is more dominant than the influence of other factors. Therefore, it is recommended that further Merah Delima papaya HYV development program needs to be supported by the assistance of providing farmers with machine-powered sprayers or prioritized at locations that have few water/irrigation management problems.
Analisis Single Nucleotide Polymorphism Gen Faktor Transkripsi MYB dalam Biosintesis Antosianin Kulit Buah Mangga (Analysis of Single Nucleotide Polymorphism Gene Transcription Factor MYB in Mango Skin Anthocyanin Biosynthesis)
Authors: Ashgi Findy , Pancoro Adi
Published: December 2021

Perkembangan pasar bebas berdampak terhadap selera produk-produk pertanian, seperti warna buah mangga. Antosianin merupakan senyawa yang bertanggung jawab dalam menginduksi warna pada buah. Senyawa ini diregulasi oleh gen faktor transkripsi MYB. Mutasi Single Nucleotide Polymorphism (SNP) daerah ekson gen MYB dapat mengubah asam amino yang memengaruhi aktivitas enzim yang mengakibatkan munculnya variasi fenotipe warna buah di antara individu-individu dalam spesies yang sama. Penelitian ini bertujuan menemukan SNP pada gen MYB dari kulit buah mangga varietas Arum Manis, Gedong Gincu, Manalagi, Golek, dan Cengkir. Penelitian dilakukan dengan tiga tahap utama, yaitu isolasi DNA kulit buah mangga, Polymerase Chain Reaction (PCR), dan proses sekuensing oleh Macrogen Inc. (Singapore). Hasil multiple sequence alignment asam amino gen faktor transkripsi MYB menunjukkan adanya perbedaan basa yang mengakibatkan munculnya stop codon dari SNP 337 A→T dan SNP 338 A→G yang memengaruhi fenotipe warna kulit buah. SNP yang memunculkan stop codon dapat direkomendasikan untuk membedakan fenotipe pigmentasi antosianin pada kulit buah mangga Gedong Gincu yang bewarna merah dengan warna kulit buah mangga yang lainnya. Adanya SNP menyebabkan prematur stop codon yang terjadi pada gen faktor transkripsi MYB dan diduga berpengaruh terhadap pigmentasi antosianin.

Abstract 

The development of free markets gives an impact on appetite for agricultural products, such as the color of mangoes fruit skin. Anthocyanins are compounds that are responsible for giving color to the fruit skin, these compounds are regulated by the MYB transcription factor genes. Single Nucleotide Polymorphism (SNP) mutations in the exon region of the MYB gene can change amino acids that affect enzyme activity, resulting in phenotypic variations in fruit color among individuals in the same species. This study aims to find SNP in MYB genes from mango peel varieties Arum Manis, Gedong Gincu, Manalagi, Golek, and Cengkir. The research was conducted in three main stages, namely isolation of mango peel DNA, Polymerase Chain Reaction (PCR), and sequencing process by Macrogen Inc (Singapore). The results of multiple sequence alignment of the amino acid MYB transcription factor genes showed a base difference which resulted in the appearance of a stop codon from SNP 337 A→T and SNP 338 A→G which affected the phenotype of fruit skin color. The SNP that raises the stop codon can be recommended to differentiate the anthocyanin pigmentation phenotype on the red skin of the mango Gedong Gincu from the skin color of other mangoes. The presence of SNP causes premature stop codon that occurs in the MYB transcription factor gene and is thought to have an effect on anthocyanin pigmentation.

Purpose: To evaluate the role of the cardiopulmonary exercise test (CPET) as a predictor of overall survival (OS) and non-relapse mortality (NRM) in patients with hematological malignancies who undergo allogeneic hematopoietic stem cell transplantation (HSCT).Methods: We retrospectively analyzed consecutive adult patients with hematological malignancies who underwent HLA-matched donor-HSCT at Chungnam National University Hospital (Daejeon, South Korea) between January 2014 and December 2020. Peak oxygen consumption (VO2max) was classified using the recommendations of the Mayo Clinic database.Results: Of 72 patients, 38 (52.8%) had VO2max values lower than the 25th percentile (VO2max < 25th) of an age- and sex-matched normal population. Patients with VO2max < 25th exhibited slightly lower OS and higher NRM (30-month OS 29.8% vs. 41%, p = 0.328; and 30-month NRM 16% vs. 3.3%, p = 0.222), compared with other patients. VO2max ≤ 25th was assigned a weight of 1 when added to the Hematopoietic Cell Transplantation-specific Comorbidity Index (HCT-CI) to form a composite comorbidity/CPET index (HCT-CI/CPET). Patients with HCT-CI/CPET scores of 0–1 demonstrated significantly better OS and NRM than did patients with HCT-CI/CPET scores ≥ 2 [median OS not reached vs. 6 months, p < 0.001 and 30-month NRM 7.4% vs. 33.3%, p = 0.006]. An HCT-CI/CPET score ≥ 2 was the only adverse risk factor for NRM on multivariate analysis [hazard ratio (HR) of NRM 10.36 (95% CI 1.486-2.25, p = 0.018)].Conclusion: The CPET may predict the survival and mortality of patients with hematological malignancies who undergo allogeneic HSCT.
