Published: April 2020

Dalam perencanaan produksi PT. Pertamina (Persero) TBBM Boyolali, perusahaan tersebut hanya mendistribusikan BBM sesuai dengan permintaan SPBU tanpa melakukan perhitungan matematis apakah pendapatan yang diperoleh sudah optimal dengan semua faktor dan kendala yang ada, seperti harga setiap jenis BBM, jam kerja mesin pengisian BBM di New Gantry System (NGS), moda transport mobil tangki, dan tingkat keselamatan mobil tangki. Untuk itu, penelitian ini bertujuan untuk melakukan optimasi perencanaan produksi BBM menggunakan metode goal programming agar perusahaan dapat memperoleh pendapatan yang maksimal dengan memperhatikan faktor-faktor dan kendala yang ada. Metode goal programming merupakan perluasan dari linear programming yang dapat menyelesaikan optimasi dengan banyak tujuan. Pada penelitian ini, selain dengan fungsi kendala biasa, metode goal programming juga digunakan untuk menyelesaikan permasalahan yang sama ditambah dengan satu fungsi kendala fuzzy, yaitu tingkat keselamatan mobil tangki, yang proses defuzzifikasinya meng­gunakan metode mamdani. Hasil penelitian menunjukkan, kedua penyelesaian metode goal pro­gramming baik dengan kendala biasa maupun dengan kendala fuzzy memberikan keluaran jumlah BBM dan jumlah pendapatan yang sama, yaitu produk premium () sebanyak 1016 kl, bio solar () seba­nyak 1200 kl, pertamax () sebanyak 596 kl, dan pertalite () sebanyak 1632 kl dengan pendapatan sebesar Rp33.022.000.000,00. Optimization planning of fuel oil production with fuzzy constraint using goal programming method AbstractIn the production planning of PT. Pertamina (Persero) TBBM Boyolali, it only distributes fuel in accordance with the demand for gas stations without performing mathematical calculations whether the revenue obtained was optimal with all the factors and obstacles that exist, such as the price of each type of fuel, working hours of filling machine fuel in New Gantry System (NGS), transport modes of the tank car, and the tank car’s safety level. Therefore, this study aims to optimize the production planning using goal programming method so that the company can obtain maximum income by considering the factors and constraints. The goal programming method was an extension of linear programming that can accomplish optimization with many goals. In this study, in addition to the ordinary constraint function, goal programming method was also used to solve the same problem which includes one fuzzy constraint, namely the level of tank car safety, which the defuzzification process using Mamdani method. The result of the study shows that solution of goal programming method both with ordinary and fuzzy constraint give the same amount of fuel output and the same amount of revenue, that is premium () as much 1016 kl, bio diesel () as much 1200 kl, pertamax () as much 596 kl and pertalite () as much 1632 kl with the revenue is Rp33.022.000.000,00.

The primary intention of the paper is to show Communism organization, expansion and operation followed by Serbian Church magazines between 1920 and 1940 in the Kingdom of Serbs, Croats and Slovenes / Yugoslavia. The author, will by analyzing all available and the relevant church newspapers from that period show how the Serbian Church magazines reacted to Communism. Special attention will be paid to the organization, expansion and (secret) action of the Communists since the founding of the Communist Party of Yugoslavia (KPY) and the Young Communist League of Yugoslavia (SKOJ) until the beginning of World War II. Communism, at the time, was a new political philosophy which was developed as a child of socialism versus capitalism. Communism slowly came to the scene of the new state which was founded after World War I. Communism using the still young, economically weaken, and we can say insufficiently organized, multinational and multi-religious Kingdom, slowly, with a great discipline of his supporters and good organization expanded its field of action. In this paper, we will talk about it, whether, and how, Serbian church magazine recognized organization and expansion of the new political thinking and how it commented on itture.

A medida que la producción acuícola aumenta con las crecientes demandas globales, su impacto en el medio ambiente también está aumentando. La liberación de desechos de acuicultura a cuerpos de agua naturales se está convirtiendo en un desafío, dado que son ricos en nutrientes orgánicos e inorgánicos que conducen a un deterioro ambiental. La intensificación de la acuicultura es una alternativa viable para aumentar la producción debido a la competencia que surgió del uso de los recursos naturales. Sin embargo, exige mayores insumos, como peces y alimentos por unidad de área de cultivo y, por lo tanto, una mayor generación de residuos de los sistemas de producción acuícola. Este documento analizó diversos aspectos de la producción de desechos de la acuicultura: sus fuentes, componentes y métodos de manejo en sistemas de cultivo en jaulas, discutiendo principalmente la producción de desechos de alimentos y heces que causan un efecto adverso grave que incluye cambios en la estructura y el funcionamiento de los ecosistemas y sedimentación de material orgánico; productos químicos como antibióticos que generan un desequilibrio en la flora bacteriana; lavado de redes aumentando la cantidad de partículas disueltas, y residuos disueltos como nitrógeno y fósforo que conducen al fenómeno de eutrofización, entre otros efectos. El objetivo fue establecer las fuentes de desechos, su contenido y los daños potenciales tanto para el cultivo de peces como para el medio ambiente. De igual manera se tiene en cuenta la normatividad de la acuicultura y pesca en Colombia y algunas medidas de mitigación que podrían adoptarse.

Se estimó la variabilidad genética de cuatro poblaciones de camarón blanco (Litopenaeus vannamei) de la costa Pacífica del departamento de Nariño (región de Tumaco), mediante el marcador genético RAPD a partir de cuatro iniciadores. Se seleccionó tres poblaciones naturales (Salahonda, Curay y La Ensenada de Tumaco), además de una población de cultivo (La Carbonera). Los resultados mostraron un número de alelos diferentes (Na) entre 1,013 y 1,178 con porcentajes de polimorfismo entre 49,04% y 55,41%. Los valores de Gst y ΦPT indican que existen diferencias genéticas entre las poblaciones estudiadas. El análisis de ΦPT entre pares de poblaciones y las distancias genéticas de Nei mostraron que la población que presentó mayor diferenciación genética fue la población de cultivo de La Carbonera, mientras que las poblaciones más similares fueron las poblaciones naturales de La Ensenada y Salahonda. La población de Curay presentó la mayor diferenciación entre las poblaciones naturales. El análisis de varianza molecular AMOVA indicó que la variabilidad encontrada se debe en mayor porcentaje (58%) a las diferencias intrapoblacionales mientras que un menor porcentaje de variación (42%) se debe a las diferencias interpoblacionales.

Представлены результаты эмпирического исследования, направленного на изучение временной перспективы родителей, воспитывающих детей с умственной отсталостью. В ходе исследования у данной категории родителей выявлены три типа временной перспективы – один гармоничный и два деформированных, причем чаще встречались деформированные типы временной перспективы. При гармоничном типе наблюдалось сбалансированное сочетание ориентаций на позитивное прошлое, гедоническое настоящее и будущее. Деформированная временная перспектива 1-го типа характеризовалась сочетанием фаталистического настоящего, негативного прошлого и низкой ориентацией на будущее. Деформированная временная перспектива 2-го типа сочетала негативное прошлое, гедоническое настоящее и низкую ориентацию на будущее. Все родители с гармоничным типом временной перспективы, выполняя графический тест Т. Коттла, показали временную связь между прошлым, настоящим и будущим. У родителей, имеющих деформированную временную перспективу 1-го или 2-го типа, по данному тесту временные зоны были либо автономными, либо взаимосвязанными. Важно отметить, что бо́льшая часть родителей с гармоничным типом временной перспективы имеет возраст от 40 до 45 лет, высшее образование, средний или высокий материальный достаток, высокий воспитательный потенциал. Трудная жизненная ситуация, связанная с присутствием в семье ребенка с умственной отсталостью, в большинстве случаев приводит к временной дезинтеграции родителей.The article analyzes the results of an empirical study aimed at studying the time perspective of parents raising children with mental retardation. In the course of the study, three types of temporal perspectives were revealed in this category of parents – one harmonious and two deformed ones, and more often deformed types of temporal perspectives were encountered. With a harmonious type of temporal perspective, a balanced combination of orientations towards a positive past, a hedonic present, and a future was observed. The deformed time perspective of type 1 was characterized by a combination of a fatalistic present, a negative past and a low orientation to the future. A deformed time perspective of type 2 combined a negative past, a hedonic present, and a low orientation toward the future. All parents with a harmonious type of time perspective, performing T. Cottle’s graphic test, showed a temporary connection between the past, present and future. For parents with a deformed time perspective of type 1 or 2, in this test, the time zones were either autonomous or interconnected. It is important to note that most of the parents with a harmonious type of time perspective were between the ages of 40 and 45, have a higher education, medium or high material wealth, and high educational potential.
Summarizing the results of the study, we can say that the difficult life situation associated with the presence of a child with mental retardation in the family, in most cases leads to temporary disintegration of parents.
ПЕДАГОГИЧЕСКИЙ ПОТЕНЦИАЛ ОБЪЕКТНОЙ КЛАССИФИКАЦИИ СОВРЕМЕННЫХ ЛИТЕРАТУРНЫХ ЭКСКУРСИЙ
Authors: Galkina Tatyana 
Published: April 2020

Необходимость выявления и осмысления педагогического потенциала литературных экскурсий обусловлена потребностью формирования компетенций будущего педагога, направленных на использование окружающей среды в качестве образовательного и воспитательного пространства. При этом необходимо различать педагогический потенциал каждого экскурсионного объекта исходя из его функциональных характеристик. Предлагаемая объектная классификация литературных экскурсий, критерием которой выступает персонификация формирующих содержание экскурсии объектов, позволяет выделить три группы объектов: прижизненные, послежизненные и искусственные. Следуя функциональным характеристикам этих объектов (у прижизненных – подлинность, у послежизненных – мемориальность, увековечение памяти, у искусственных – досуг), предлагается создавать комплекс литературных экскурсий. Такой комплексный подход позволяет узучать жизнь и творчество литераторов, погружаясь сначала в биографические материалы (прижизненные объекты: дома, квартиры, музеиусадьбы, музеи-заповедники), затем в эстетику мемориальных памятников и некрополей (послежизненные объекты) и знакомясь с воссозданными фантазиями (искусственные объекты: тематические парки под открытым небом и музеи). Таким образом, путь осмысления педагогического потенциала различных литературных экскурсий (литературно-биографических, историко-литературных, литературно-краеведческих, литературно-художественных) будет способствовать формированию духовного мировоззрения будущего педагога.The need to identify and understand the pedagogical potential of literary excursions is based on the need to form the scope of competence for future teachers which is aimed at using the environment as an educational space. It is necessary to distinguish the pedagogical potential of each excursion object on the basis of its functional characteristics. The suggested object classification of literary excursions, the criterion of which is the object personification forming the excursion content, allows dividing these objects into three groups: lifetime, afterlife and artificial objects. It is suggested to create a complex of literary excursions following functional characteristics of these objects (lifetime – authenticity, afterlife – memorialization, artificial – leisure). This complex approach allows to study the life and work of writers plunging first into biographical materials (lifetime objects: houses, apartments, estate museums, reserve museums), then into the aesthetics of memorial monuments and necropolises (afterlife objects) and, finally, into getting to know recreated fantasies (artificial objects: open-air theme parks, museums). Thus, the way of pedagogical potential understanding of various literary excursions (literary and biographical, historical and literary, literary and regional, literary and artistic) will contribute to the spiritual world view formation of future teachers.
The Moving Average Filter of Stator Current as Alarm for Overload of Induction Motor
Authors: Kekovic Goran , Stamenkovic Negovan 
Published: April 2020

In this paper, the method of detecting the overload of the induction motors (IMs) by applying moving average filter of the stator current in the time domain, was suggested. This method can be analyzed as the part of the analysis of the motor current signature analysis (MCSA). The stator current is analysed as the signal and it is divided into regular intervals – windows, within moving average filter applied. The minimum length of the moving window is determined by the sampling frequency detector, as well as the frequency of the stator current. The better resolution of peaks in moving average filter, can be achieved by the greater length of moving window. This is particularly important in areas of variable torque induction motor. This opens the possibility of detecting finer changes in the value of the stator current. It is shown that within the time window of changes in load of IMs, the signal of stator current becomes non-stationary. Otherwise, it is stationary. The changes of stationarity of the signal could be the alarm of overload of induction motor. The advantage of this method is improved response time of detector due to changes in the stator current. Software solution of proposed method is relatively simple: time series of the stator current is mapped according to the action of the moving average filter in different time series, suitable for use in real-time.

Published: April 2020

Kruja is a middle range city located in the center of Albania. The city of Kruja dates back to its existence from the V-VI century and extends to the city around the VI and IX centuries. It becomes the first capital of Albania in the XI-th century, specifically in 1190. This paper is going to deal with only two groups of buildings which are an integral part of the historical city of Kruja, the historical dwellings (XVIII century) and socialist ones (1960-1970).The aim of this paper is to analyze through linear regressions the relation between two parameters: moisture level and temperature of the indoor walls and floors of the historic and socialist buildings in the city of Kruja. Three types of historic dwelling and three types of socialist apartments have been analyzed, relatively uniformly oriented. The measurements with specific instruments are done in the same day, during three hours. The degree of reactivity is different for both groups of buildings. The historical buildings are more sensitive to temperature rise. They respond invers to it (as the temperature rise, the level of the moisture decreases), with a higher coefficient than socialist ones and appear to be more efficient in reducing the moisture level, despite the average humidity level is higher. This paper takes into consideration also the analyze of the materials of the construction for both categories. If the level of the moisture is reduced, the buildings will be improved and the quality of life indicators of the inhabitance will be improved too.
