Published: November 2022

Soybean plants have limited growth with a planting period of 12 weeks, which causes the observed sample to be very small. A small sample of soybean plant growth observations can be bias causes in the conclusion of prediction results on soybean plant growth. The  purpose this study is to apply  the bootstrap resampling technique in Gompertz growth model which overcomes residual distribution with small samples, the research data was taken from soybean plant growth in four varieties with four spacing treatments, five replications and twelve weeks (long planting period).   Gompertz growth model uses nonlinear least squares method in estimating parameters with Levenberg–Marquardt iteration. The value of the Gompertz model after resampling bootstrap has no significant difference. The adjusted R2 value of 0.96 is close to 1. This means that the total diversity of plant heights can be explained by the Gompertz model of 96 percent. Judging from the graph of predictions of soybean plant growth before resampling and after resampling coincide with each other it can also be seen in the initial growth values before resampling 14, 05 and 14.18, the maximum growth values are 55.13 and 55.60. Bootsrap resampling technique can overcome residual normality in the Gompertz growth model, but does not change the information in the initial data.

Systematic Literature Review Robust Graph Coloring on Electric Circuit Problems
Authors: Balqis Viona Prisyella , Chaerani Diah , Napitupulu Herlina
Published: November 2022

Graph Coloring Problem (GCP) is the assignment of colors to certain elements in a graph based on certain constraints. GCP is used by assigning a color label to each node with neighboring nodes assigned a different color and the minimum number of colors used. Based on this, GCP can be drawn into an optimization problem that is to minimize the colors used. Optimization problems in graph coloring can occur due to uncertainty in the use of colors to be used, so it can be assumed that there is an uncertainty in the number of colored vertices. One of the mathematical optimization methods in the presence of uncertainty is Robust Optimization (RO). RO is a modeling methodology combined with computational tools to process optimization problems with uncertain data and only some data for which certainty is known. This paper will review research on Robust GCP with model validation to be applied to electrical circuit problems using a systematic review of the literature. A systematic literature review was carried out using the Preferred Reporting Items for Systematic reviews and Meta Analysis (PRISMA) method. The keywords used in this study were used to search for articles related to this research using a database. Based on the results of the search for articles obtained from PRISMA and Bibliometric R Software, it was found that there was a relationship between the keywords Robust Optimization and Graph Coloring, this means that at least there is at least one researcher who has studied the problem. However, the Electricity keyword has no relation to the other two keywords, so that a gap is obtained and it is possible if the research has not been studied and discussed by other researchers. Based on the results of this study, it is hoped that it can be used as a consideration and a better solution to solve optimization problems.

Berdasarkan data statistik BPS untuk produksi jagung tahun 2016 provinsi NTB mencapai 1.278.271 ton dan mengalami peningkatan ditahun 2017 mencapai 2.127.324 ton, berdasarkan data tersebut tidak menutup kemungkinan jagung akan menghasikan tongkol jagung yang potensial untuk dikembangkan menjadi bioetanol dan bioenergi. Tujuan penelitian ini adalah untuk merancang bangun alat kompor gasifikasi biomassa limbah tongkol jagung skala rumah tangga, mengetahui pengaruh variasi kecepatan aliran udara  terhadap temperatur ruang pada proses pembakaran limbah tongkol jagung, mengetahui  perbandingan temperatur  pendidihan air pada variasi kecepatan aliran udara 5.0 m/s, 10.0 m/s, dan 15.0 m/s. Metode penelitian yang digunakan adalah metode experimental dengan melakukan percobaan dan uji performansi di Laboraturium Perbengkelan Pertanian. Penelitian dilakukan dengan cara memvariasikan kecepatan udara yang masuk kedalam reaktor dengan variasi kecepatan 5,0 m/s, 10,0 m/s dan 15,0 m/s. Parameter yang diamati meliputi temperatur ruang pembakaran, temperatur pendidihan air, dan waktu penyalaan awal. Hasil penelitian menunjukkan variasi kecepatan udara 15.0 m/s berpengaruh terhadap temperatur pembakaran tertinggi dengan 359,13 dengan berat abu 100 gram, kemudian temperatur  pendidihan air tertingginya 60℃, dan penyalaan awal tercatat pada menit ke 2:20:31. Dari hasil penelitian tersebut dapat dikatakan bahwa dengan menggunakan variasi kecepatan tertinggi dapat menghasilkan pembakaran yang sempurna.

Вiography of hieromonk Diomid (Egorov) based materials of the Florensky-Archive
Authors: Горячев Даниил Аркадьевич
Published: November 2022

Целью данной статьи является обобщение разрозненных и малочисленных сведений о жизни иеромонаха Диомида (Егорова), послужившего в годы гонений делу сохранения святынь Троице-Сергиевой лавры. Статья уточняет факты его биографии, в частности, документально подтверждает дату и место его смерти, делает попытку дать представление о его личности. В статье рассматриваются вопросы о том, почему отец Диомид был глубоко предан возложенному на него послушанию ризничего Троице-Сергиевой лавры и не послужило ли это следование своему долгу по спасению ризницы монастыря причиной компрометирующих его ответов, данных им в ходе допросов по сергиево-посадскому делу 1928 г. Реконструкция событий жизни иеромонаха Диомида, ставшего сотрудником Музея историко-художественных ценностей в первые годы его существования на территории Троице-Сергиевой лавры, оказалась возможной благодаря сохранившемуся архиву профессора МДА священника Павла Флоренского. Особая заслуга по изучению и публикации материалов этого архива принадлежит игумену Андронику (Трубачеву). В статье отмечается характерная черта, связывающая священника Павла Флоренского и игумена Андроника (Трубачева), названная историческим навыком или исторической интуицией - способностью замечать и сохранять существенные детали, имеющие историческое значение.

The purpose of this article is to summarize scattered and scarce information about the life of hieromonk Diomid (Egorov), who served during the years of persecution to preserve the shrines of the Trinity-Sergius Lavra. The article clarifies the facts of his biography, in particular, documents the date and place of his death, makes an attempt to give an idea of his personality. The article discusses the questions of why Father Diomid was deeply devoted to the obedience of the sacristan of the Trinity-Sergius Lavra entrusted to him and whether this adherence to his duty to save the sacristy of the monastery caused compromising answers given by him during interrogations on the Sergiev Posad case in 1928. The reconstruction of the events of the life of hieromonk Diomid, who became an employee of the Trinity-Sergius Lavra Museum in the early years of its existence, was made possible thanks to the preserved archive of the professor of the MDA priest Pavel Florensky . A special merit for the study and publication of the materials of this archive belongs to hegumen Andronik (Trubachev). The article notes a characteristic feature connecting priest Pavel Florensky and hegumen Andronik (Trubachev), called historical skill or historical intuition - the ability to notice and preserve essential details of historical significance.
Parish clergy of Northern Kazakhstan in the context of the new course of the confessional policy of the Soviet state (1940-1950)
Authors: Березин Михаил Анатольевич
Published: November 2022

Вопрос о служении приходского духовенства на территории Северного Казахстана напрямую связан с изменением характера церковно-государственных отношений в период Великой Отечественной войны. Подъем религиозности во время войны вынудил руководство СССР отойти от политики массовых репрессий в отношении православного духовенства и пойти на восстановление ранее практически полностью уничтоженных церковных структур. Процесс реставрации церковной жизни в Северном Казахстане напрямую связан с пребыванием на территории региона большого количества ссыльных священнослужителей и монашествующих, сыгравших большую роль в возрождении приходской жизни в 1940 - 1950 гг. В статье раскрывается тема взаимоотношений советских властей и православного духовенства Северо-Казахстанского региона. Автор акцентирует внимание на всеобъемлющем контроле Совета по делам Русской Православной Церкви в отношении различных аспектов пастырского служения духовенства. В работе приводится информация о числе открытых приходов, количественном и качественном составе священнослужителей региона, а также секретная переписка между председателем Совета Г. Г. Карповым и уполномоченным по Казахской республике С. Вохмениным. Работа основана на ранее секретных и неопубликованных документах из фондов Центрального Государственного архива Республики Казахстан (г. Алматы).

The issue of the ministry of the parish clergy in the territory of North-Kazakhstan is directly related to the change in the nature of church-state relations during the Great Patriotic War. The rise of religiosity during the war forced the Soviet leadership to abandon the policy of mass repression against the Orthodox clergy and go to the restoration of previously almost completely destroyed church structures. The process of restoration of church life in North-Kazakhstan is directly related to the presence on the territory of the region of a large number of exiled clergy and monastics, who played an important role in the revival of parish life in 1940-1950. The article reveals the topic of the relationship between the Soviet authorities and the Orthodox clergy of the North Kazakhstan region. The author focuses on the comprehensive control of the Council for the Affairs of the Russian Orthodox Church in relation to various aspects of the pastoral ministry of the clergy. The paper provides information on the number of open parishes, the quantitative and qualitative composition of the region's clergy, as well as secret correspondence between the chairman of the Council G. G. Karpov and the authorized representative for the Kazakh Republic S. Vokhmenin. The work is based on previously secret and unpublished documents from the funds of the Central State Archives of the Republic of Kazakhstan (Almaty).
China - India cultural interaction: The competition of “soft powers”?
Authors: Muratshina Ksenia G.
Published: November 2022

The paper analyses how the People’s Republic of China and the Republic of India develop such area of bilateral relations as cultural exchanges at the current stage. The authors trace the two countries’ interaction during five consecutive years: 2017, 2018, 2019, 2020 and 2021 (that means, there are displayed both the relations before the COVID-19 pandemic and the interaction in current conditions. At the same time, it is the opportunity to take a glance at the cultural exchanges between the states during different stages of their relationship: both in the times of its deterioration and normalization). The types of exchanges, which have been studied, include the weeks of culture, the year of cultural exchanges, the organisation of exhibitions, festivals, movie demonstrations, concerts, musical tours, master classes of yoga, meetings of artists, visits of youth delegations, cultural forums, dialog between the ministries of culture, and regular small-scale events at embassies and consulates.
As a result of the study, the specific features of bilateral cultural exchanges are outlined. The authors conclude that by means of this area of relations both China and India pursue a broader set of goals, than just to secure the conditions of peaceful coexistence and to improve mutual understanding between the nations. The case is that for both countries, competing for leadership in Asia, cultural interaction is another ground for rivalry, this time in struggling for minds and hearts of people, and a tool for improving their images in order to achieve a better position in the relationship in future.
Russia-Vietnam cooperation under international sanctions against Russia
Authors: Korgun Irina A.
Published: November 2022

This paper analyses a preliminary impact of the international sanctions against Russia on Russia-Vietnam bilateral relations. Authors use trade data for the first five months of 2022 to understand trade flows between Russia and Vietnam. The data reveal a sharp decline both in volume and value across all major categories of export and import. The decline comes as a reaction towards the disruption of payments following SWIFT ban on the Russian banks. Also, the ban on shipments to Russia by international marine companies deepened the negative impact in the first months after sanctions had been introduced.
In terms of geopolitical consequences of the sanctions, Vietnam is increasingly worried about the growing strategic presence of the US in Southeast Asia because this presence can lead to a confrontation between America and China which are both important economic partners to Vietnam. The US strategic presence in the region is somewhat undesirable for Vietnam and several other countries because it can damage their military cooperation with Russia. From this perspective, Vietnam views Russia’s presence in Southeast Asia as a crucial element in balancing rivalries and maintaining operational capabilities of strategic forces of several countries of the region, including its own. Vietnam has to act very carefully to avoid damaging its economic momentum obtained through closer linkages with the West and keeping its national strategic interests.
The paper concludes with a review of economic opportunities for Russia and Vietnam under the current circumstances and offers several aspects that need to be reinforced to develop the bilateral cooperation in the near future.
