Authors: Wardani Dyah Woro Kartiko Kusumo , Eviyani Margaretha Manungkalit
Published: December 2022

Stunting merupakan kondisi dimana balita menurut usianya (0 – 5 tahun) memiliki panjang atau tinggi badan dengan hasil nilai z-score dibawah -2SD berdasarkan standar pertumbuhan menurut WHO. Kondisi stunting mengakibatkan terhambatnya perkembangan kognitif dan motorik sehingga menciptakan generasi yang kurang berdaya saing serta mengganggu sistem metabolik yang beresiko terjadinya berbagai penyakit. Stunting disebabkan oleh faktor multi dimensi, diantaranya yaitu panjang badan lahir yang dipengaruhi nutrisi saat hamil dan genetik, tinggi badan orang tua yang dapat diturunkan kepada anakkya, status ekonomi yang berhubungan dengan kemampuan pemenuhan gizi, pendidikan yang mempengaruhi pengetahuan terkait gizi dan pola asuh anak. Penelitian ini bertujuan menganalisis faktor yang berhubungan dengan kejadian stunting pada anak usia 6-24 bulan di Jakarta Pusat dengan metode cross sectional menggunakan kuesioner. Analisis menggunakan Chi-square untuk mengetahui hubungan antara faktor penyebab stunting dan menggunakan uji regresi logistik ganda untuk mengetahui faktor yang paling berpengaruh terjadap kejadian stunting. Hasil penelitian menunjukkan tidak ada hubungan antara pendidikan, usia pendapatan keluarga, jarak kehamilan, IMT, panjang badan lahir dan pemberian ASI eksklusif dengan kejadian stunting (P >0,05) serta ada hubungan antara tinggi badan ibu dengan kejadian stunting (p<0.05). Sedangkan, hasil uji regresi menunjukkan faktor yang paling berpengaruh terhadap kejadian stunting adalah tinggi badan ibu.

Authors: Citra Ayu Larasati  , Pariyanto
Published: December 2022

This research explored the types of word formation processes in the descriptions of cosmetic products. This descriptive qualitative study employed the classification of word formation processes proposed by Yule’s (2010)—derivation, compounding, conversion, borrowing, blending, acronym, backformation, coinage, clipping, and multiple processes to analyze the data. The data were taken from the descriptions of cosmetic products in the beauty brands by U.S celebrities—Fenty Beauty, Rare Beauty, Kylie Cosmetics, and Florence by Mills which were released and in production in April, 2022. This study discovered 125 word-formation processes including derivation (42), conversion (29), multiple processes (17), compounding (16), clipping (8), borrowing (7), acronym (3), coinage (2), and blending (1). This study implies that derivation is the most frequently used in the product descriptions, suggesting that the use of derivation creates adjectives that modifies the products.

В аналитической форме исследуются жесткость и первая собственная частота колебаний балочной фермы. Опоры фермы шарнирные. Методом индукции разыскиваются аналитические выражения для прогиба и нижней границы частоты собственных колебаний фермы с использованием формулы Донкерлея при произвольном числе панелей. Предполагая, что масса фермы сосредоточена в ее узлах, каждая масса имеет одну степень свободы, а жесткость стержней одинаковая. По результатам вычислений прогиба в серии однотипных ферм с разным числом панелей выводится искомая зависимость прогиба от нагрузки, упругих свойств стержней и числа панелей. Решение системы линейных уравнений для определения усилий в стержнях и все преобразования производятся в пакете компьютерной математики Maple. Для расчета жесткости фермы используется формула Максвелла-Мора. Найдена линейная асимптотика решения задачи о прогибе. Аналитическая оценка частоты сравнивается с низшей частотой всего спектра частот, найденного численно. Точность полученной аналитической оценки возрастает с увеличением числа панелей.

In an analytical form, the stiffness and the first natural frequency of vibrations of a beam truss are investigated. The truss supports are articulated. Analytical expressions for the deflection and the lower limit of the frequency of natural vibrations of the truss using the Dunkerley formula for an arbitrary number of panels are searched for by the induction method. Assuming that the mass of the truss is concentrated in its nodes, each mass has one degree of freedom, and the rigidity of the rods is the same. Based on the results of deflection calculations in a series of similar trusses with different numbers of panels, the desired dependence of deflection on load, elastic properties of rods, and the number of panels is derived. The solution of the system of linear equations for determining the forces in the rods and all transformations are made in the Maple computer mathematics package. To calculate the stiffness of the truss, the Maxwell - Mohr formula is used. A linear asymptotics for the solution of the deflection problem is found. The analytical frequency estimate is compared with the lowest frequency of the entire frequency spectrum found numerically. The accuracy of the analytical estimate obtained increases with the number of panels.

В работе приведен пример построения ядра сечения для стержней с криволинейной формой поперечного сечения. Подробное описание данного метода представлено в двух последних источниках, приведенных в списке литературы к данной статье. Кроме того, в статье приведен вывод уравнения касательной к ядру сечения, отсутствовавший в предыдущих источниках. Примененная методика построения ядра сечения является оригинальной. Она пользуется заменой графического представления касательной к контуру поперечного сечения на аналитическое, исходя из геометрического смысла первой производной от функции, описывающей уравнение соответствующего контура. Это уравнение записывается применительно к главным центральным осям инерции поперечного сечения. Предварительно необходимо вычислять следующие геометрические характеристики: площадь поперечного сечения, главные центральные моменты инерции (с использованием интегральных зависимостей) и квадраты радиусов инерции. Данную методику построения ядра сечения удобно применять, если одна или две главные центральные оси являются осями симметрии. В качестве симметричной функции рассмотрена синусоида (косинусоида).

In this paper, an example of constructing a cross-section core for rods with a curved cross-section shape is given. A detailed description of this method is given in the last two sources listed in the list of references to this article. In addition, this article presents the derivation of the equation of the tangent to the core of the section, which was absent in previous sources. The applied method of constructing the cross-section core is original. It uses the replacement of the graphical representation of the tangent to the contour of the cross section with an analytical one, based on the geometric meaning of the first derivative of the function describing the equation of the corresponding contour. This equation is written in relation to the main central axes of inertia of the cross section. Previously, it is necessary to calculate the following geometric characteristics: the cross-sectional area, the main central moments of inertia (using integral dependencies) and the squares of the radii of inertia. This method of constructing the cross-section core is convenient to use if one or two main central axes are axes of symmetry. In this paper, a sinusoid (cosine) is considered as a symmetric function.

Published: December 2022

Выполнен анализ динамики и прочности пакетов сэндвич-панелей как трехслойных конструкций под действием нагрузок, приводящих к значительным деформациям при длительной транспортировке. Разработаны конечно-элементные модели, учитывающие особенности взаимодействия панелей, размещенных в транспортных пакетах. Получены значения собственных частот колебаний рассмотренных систем. Показано, что низшие частоты колебаний пакетов сэндвич-панелей лежат в диапазоне частот вынуждающих сил, возникающих при движении транспортного средства по дороге. Анализ напряжений, возникающих в панели нижнего яруса, показал, что в случае совместного действия сил инерции, связанных с торможением автомобиля, сил тяжести и сил прижатия ремней крепления при числе десяти и более панелей в штабеле в среднем слое нижней панели возникают напряжения, превышающие предел прочности материала. Полученные результаты показали, что обеспечить прочность транспортируемых панелей при перевозке их пакетов в два яруса возможно только при жесткой упаковке панелей нижнего яруса.

The analysis of the dynamics and strength of sandwich-panel packages, as three-layer structures, under the action of loads, leading to significant deformations during long-term transportation, was carried out. Finite element models have been developed that take into account the peculiarities of the panels placed in transport packages interaction. The values of Eigen frequencies of considered systems oscillations are obtained. It is shown that the lowest oscillation frequencies of the sandwich panel packages lie in the frequency range of the driving forces that occur when the vehicle moves along the road. An analysis of the stresses arising in the panel of the lower tier showed that in the case of the combined action of the forces of inertia associated with the braking of the car, the forces of gravity and the forces of pressing the fastening belts with a number of ten or more panels in a stack, stresses arise in the middle layer of the lower panel that exceed the tensile strength material. The obtained results showed that it is possible to ensure the strength of the transported panels when transporting their packages in two tiers only if the panels of the lower tier are rigidly packed.

The paper presents the mechanisms of modification and formation of metamorphosed compacted clay soils; the mechanical properties of clay soil samples modified with dispersed foam concrete and slaked lime were determined; a design scheme for a soil pad made of clay soil modified with dispersed foam concrete and slaked lime was created; the optimal geometric parameters of the soil cushion for the construction of buildings and structures have been established; the stress-strain state of a weak base reinforced with a soil cushion made of modified clay soil was determined.

Draft programme of the celebrations of the anniversary of the Governance Act
and the course of the celebrations in Warsaw in 1792

The aim of the article is to present the work on the programme for the Warsaw celebrations of the first anniversary of the adoption of the Constitution of 3 May. The subject matter of the article has not so far been examined in historiography in great detail. The source materials used are: the correspondence of Polish politicians and diplomats of foreign states (Russia, Prussia, Austria) residing in Poland, and a hitherto unknown draft of the programme of the celebrations planned for 3 May 1792. The article contains a timeline of the work on the celebrations of the first anniversary of the Governance Act. The author also analyses the work of the Sejm concerning the anniversary of the 3 May revolution. The idea to organise such celebrations was put forward by Hugo Kołłątaj in late February 1792, after the completion of assemblies convened to adopt a position on the constitution promulgated in the previous year. Wojciech Szczygielski calls the campaign carried out at the time a “3 May referendum”. The final version of the scenario of the celebrations was formulated in late April that year. The author points to the changes in the planning of the various elements of the ceremony: name-day wishes for the king, audience at the Holy Cross Church and laying of the foundation stone for the construction of the Church of Divine Providence. Of crucial importance was a change in the ideological tone of the planned celebrations. Like during the work on the Constitution of 3 May, two ideologies, monarchism and republicanism, clashed during the preparations of the programme for celebrations. The latter won.
Wydrzeć tradycję konformizmowi. O ludowych historiach Polski

To wrest tradition away from conformism. On people’s histories of Poland

In the article I review and discuss recent books on people’s history of Poland. The first part is a classic review of the books Ludowa historia Polski [A People’s History of Poland] by Adam Leszczyński, Chamstwo by Kacper Pobłocki and Siła podporządkowanych [The Power of the Subjugated] by Michał Rauszer. I draw attention, among others, to the one- sidedness of the narrative (a dichotomous division of society, focus on the violence and its continuity), interpretations that are not supported by the arguments and sources presented (strzygoń, the vampire from Slavic folklore), and to the lack of a global perspective. While in the first part the discussion is on the level of content, in the second part the key concepts, ideas and assumptions behind the writing of people’s histories are considered — how and for whom such histories should be communicated, what is their purpose. Following Walter Benjamin and Mark Fisher, I propose that people’s history should open up the past and remind us that alternatives to the dominant system were and are possible.

Sigismund III Vasa and the Grand Duchy of Lithuania.
In search of a modus operandi (Karol Żojdź, Wszyscy ludzie króla. Zygmunt III Waza i jego stronnicy w Wielkim Księstwie Litewskim w pierwszych dekadach XVII wieku, Wydawnictwo Naukowe Uniwersytetu Mikołaja Kopernika, Toruń 2019, 454 pp.)

The aim of the review article is to assess the scholarly value of Karol Żojdź’s book devoted to the Sigismund III’s faction in the Grand Duchy of Lithuania. The analysis is focused on the author’s concept and methodology, pointing to their strengths as well as debatable points. The assessment also concerns the relations between the monarch and members of the Lithuanian elite, ways used by the king to influence various followers as well as the conclusions, presented in the book, concerning the composition and characteristics of the faction. The broad research perspective presented in the monograph makes it possible to view the analysed group in a multifaceted manner and to capture the mechanisms used by the Vasa ruler to build his political base.

Published: December 2022

The world has been shifting toward all things digital for a very long time. But the year 2020 made clear how critical it is to quickly adopt new technology. This modification took place fairly immediately after the lockdown was put into place, especially in India for digital payments. Since demonetization in 2016 the Indian government has aggressively promoted and spread online payments. The myriad economic and financial considerations that compelled Indians to change online payments were all motivated by the idea of "Digital India." Making sure there is financial equality becomes a matter of the utmost significance in a country like India where differences might occasionally be different.

The background that drives this research is that students have difficulty understanding science material, lack of students' understanding of science material, learning activities have not used effective learning models, and student learning outcomes have not been maximized. The problem in this study is whether there is an effect of the problem based learning model on the learning outcomes of science class V SDN 1 Godong?. The purpose of this study was to determine the effect of the problem based learning model on the learning outcomes of fifth grade science students at SDN 1 Godong. This study uses a quantitative method with a pre-experimental design in the form of a one-group pretest-posttest design. Data collection techniques in this study through interviews, observations, tests, and documentation. The results showed that the average pretest was 46.8 and the average posttest was 87.9. Based on the paired sample t-test with df = N-1 = 32-1 = 31 with a significant level of 0.05, it was obtained tcount = 14,442 ttable = 2,039. From the results of these calculations obtained tcount > ttable, it can be concluded that there is a difference and mastery of learning from the problem based learning model on the learning outcomes of science class V SDN 1 Godong. Based on the research results obtained, the authors suggest that the application of the problem based learning model can be developed into an effective and fun learning activity.
