Buah Jambu biji adalah buah yang banyak mengandung vitamin dan baik bagikesehatan. Jambu biji juga memiliki tingkat permintaan tinggi di Indonesia dan memiliki pasar yang luas. Hal ini membuktikan bahwa jambu biji dikonsumsi oleh masyarakat secara luas dan memiliki tingkat daya saing tinggi. Selama ini pengklasifikasian mutu jambu biji dilakukan dengan melakukan pengamatan manual dengan melihat secara langsung permukaan fisik luar buah. Pengklasifikasian secara manual ini memberikan hasil klasifikasi yang kurang efektif dan tidak konsisten. Teknologi pengolahan citra digital atau Image Proseccing dapat digunakan untuk mengklasifikasikan mutu jambu biji getas merah yang sesuai dengan Standar Nasional Indonesia, terutama dari segi tekstur luar jambu biji. Sistem ini menggunakan pengolahan citra untuk mengekstraksi ciri tekstur luar permukaan buah jambu biji. Sebagai klasifikasi mutu digunakan metode KNN (K-Nearest Neighbour). Sistem ini akan mengklasifikasikan jambu biji ke dalam 3 kelas mutu, yakni kelas super, kelas A, dan kelas B,. KNN dirancang dengan masukan 4 fitur ekstraksi nilai GLCM (energy, homogeneity, correlation dan contrast) dengan menggunakan sudut 0 derajat. Dari hasil pengujian didapatkan bahwa metode klasifikasi ini mampu memberikan akurasi terbaik pada k=9 dalam metode KNN dengan akurasi 45,8%.

Рассмотрены подходы по созданию новых элементов программным копированием, образованных от имеющихся 3D-моделей и представленных в экспортных форматах данных. Подготовлена структурная схема для проектирования программ по созданию копий элементов относительно базовых моделей с импортируемой геометрией. Для создания ассоциативных копий импортируемых моделей разработан автономный программный модуль. Программное решение в реализации построения копий выполнено на классах и методах открытого геометрического ядра Open CASCADE, где посредством диалогов, а также с помощью вспомогательных элементов производится построение подобных элементов от имеющихся моделей. Доступны режимы работы, когда копии могут быть получены по направлениям, по окружности относительно точки, масштабированием, зеркальным копированием и прочими подходами к моделированию тел. В проекте имеется возможность расширения функционала для получения ассоциативных копий элементов с использованием массивов данных и импортом параметров, представленных табличным видом. Кроме того, в программном модуле реализованы средства просмотра и представления моделей, а также их копий в отдельном масштабируемом окне, имеется функционал для изменения цвета моделей, удаления выборочной копии объекта, сохранения результатов в открытых экспортных форматах CAD систем. Разработка выполнена с использованием 64-х разрядной архитектуры операционных систем Windows

The article discusses approaches to creating new elements by programmatic copying, formed from existing 3D models and presented in export data formats. We made a block diagram for designing programs for creating copies of elements relative to base models with imported geometry. To create associative copies of imported models, we developed an autonomous software module. We performed the software solution in the implementation of building copies on the classes and methods of the open geometric core Open CASCADE, where, through dialogues, as well as with the help of auxiliary elements, similar elements are constructed from existing models. Modes of operation are available when copies can be obtained in directions, along a circle relative to a point, scaling, mirroring and other approaches to modeling bodies. The project has the ability to expand the functionality to obtain associative copies of elements using data arrays and importing parameters presented in a tabular form. In addition, the software module implements tools for viewing and presenting models, as well as their copies in a separate scalable window, there is functionality for changing the color of models, deleting a selective copy of an object, saving results in open export formats of CAD systems. The development was carried out using the 64-bit architecture of Windows operating systems

Published: July 2021

Agada tantra is one of the unique branches among the eight branches of Ayurveda which deals with different poisoning conditions, diagnosis, and treatment. In Ayurveda Garavisha(~artificial poison) is mentioned as a type of Visha(~poison) which is formed by the combination of two or more poisonous or non-poisonous substances, which slowly gets accumulated in the body and ultimately affects all parts of the body by vitiating all Dosha(~humor), Dhatu(~tissues), Mala(~waste products) and Srotas(~channels). Many ayurvedic formulations are mentioned for the treatment of Garavisha. Ajeya ghrita is one among them which is explained in Ashtanga Sangraha. It is a form of Ghrita Kalpa (~ghee preparation), the use of Ghrita (~poison) plays an important role in the management of Visha (~poison) condition. Ajeya ghrita is a formulation that has a combination of many herbs, in which most of the herbs possess Vishahara (~antipoison) property. The ingredients are easily accessible and have a simple method of preparation may encourage the physician to use this formulation in the management of Visha (~poison) condition. Hence an effort is made to review the Ajeya ghrita for Vishahara (~anti-poison) property.

Published: July 2021

Using the descriptive research design, this study aimed to do a results-based analysis of online and modular distance learning of the students’ academic performance in English on first and second quarter of school year 2020-2021 in Don Manuel Rivera Memorial National High School. The respondents of the study were composed of 50 Online Distance Learning (ODL) Students and 250 Modular Distance Learning (MDL) Students from Grades 7 to Grade 10 levels of Don Manuel Rivera Memorial National High School.
This is a descriptive study using the questionnaire as the main tool in gathering the data. The data gathered were treated using frequency distribution and percentage statistics, weighted mean, standard deviation, and T-test.
The mean level of parents’ support to ODL students was 2.72 interpreted as “Moderately Supportive” indicates that parents are somehow extending additional support to their children in accomplishing the tasks given to them. On the other hand, the mean level of parents support to MDL students was 2.95 interpreted as “Moderately Supportive” indicates that only few parents extend their support to their children despite the awareness that their children have no direct contact to their subject teachers to give them assistance in understanding the lessons. This concludes that students under online distance learning gets more instructional support rather than the students under modular distance learning which gives a huge impact to their academic performances.

Authors: Regiel V. Condino
Published: July 2021

The study focused on the lived experiences of English teachers in Online Distance Learning (ODL) in the new normal. The study aimed to determine the degree of the pre-identified challenges and their feelings about teaching through ODL. The participants of this study involved five (5) Junior High School English teachers of the Basic Education Department (BED) in private schools in Laguna, Philippines in this first school year under the new normal, the SY 2020-2021. The study employed quantitative and qualitative research methods. The researcher obtained the mean from the raw data of the pre-identified challenges in teaching English through ODL in three (3) aspects: preparations, conduct of lessons, and assessment and feedback. The results revealed that the participants, being in ODL modality for almost a year now, found preparations very easy, having a mean of 3.40. Consequently, they considered that in the other two (2) aspects, they did not find much difficulty with 3.00 as the mean as the school year ended. These results showed that the participants have a low degree of difficulty in the pre-determined challenges as experienced in the ODL. This is due to their adjustment for a year now being first time-teachers in this new normal. As for the qualitative results, the hermeneutic phenomenology was used to identify their feelings about their teaching through ODL. Eight (8) themes emerged about their feelings in the beginning, middle, and end of the school year. At the beginning of the school year, the teachers had feelings of anxiety and challenge. In the middle of the school year, they had feelings of inefficiency and stress. However, they also felt hopeful that this pandemic would soon be over. Lastly, at the end of the school year, the teachers concluded their first school year in ODL with the feelings of fulfillment, confidence, and resilience.

A Greedoid and a Matroid Inspired by Bhargava's $p$-Orderings
Authors: Grinberg Darij , Petrov Fedor
Published: July 2021

Consider a finite set $E$. Assume that each $e \in E$ has a "weight" $w \left(e\right) \in \mathbb{R}$ assigned to it, and any two distinct $e, f \in E$ have a "distance" $d \left(e, f\right) = d \left(f, e\right) \in \mathbb{R}$ assigned to them, such that the distances satisfy the ultrametric triangle inequality $d(a,b)\leqslant \max \left\{d(a,c),d(b,c)\right\}$.

We look for a subset of $E$ of given size with maximum perimeter (where the perimeter is defined by summing the weights of all elements and their pairwise distances). We show that any such subset can be found by a greedy algorithm (which starts with the empty set, and then adds new elements one by one, maximizing the perimeter at each step). We use this to define numerical invariants, and also to show that the maximum-perimeter subsets of all sizes form a strong greedoid, and the maximum-perimeter subsets of any given size are the bases of a matroid. This essentially generalizes the "$P$-orderings" constructed by Bhargava in order to define his generalized factorials, and is also similar to the strong greedoid of maximum diversity subsets in phylogenetic trees studied by Moulton, Semple and Steel.

We further discuss some numerical invariants of $E, w, d$ stemming from this construction, as well as an analogue where maximum-perimeter subsets are replaced by maximum-perimeter tuples (i.e., elements can appear multiple times).
Connector-Breaker Games on Random Boards
Authors: Clemens Dennis , Kirsch Laurin , Mogge Yannick
Published: July 2021

By now, the Maker-Breaker connectivity game on a complete graph $K_n$ or on a random graph $G\sim G_{n,p}$ is well studied. Recently, London and Pluhár suggested a variant in which Maker always needs to choose her edges in such a way that her graph stays connected. By their results it follows that for this connected version of the game, the threshold bias on $K_n$ and the threshold probability on $G\sim G_{n,p}$ for winning the game drastically differ from the corresponding values for the usual Maker-Breaker version, assuming Maker's bias to be 1. However, they observed that the threshold biases of both versions played on $K_n$ are still of the same order if instead Maker is allowed to claim two edges in every round. Naturally, this made London and Pluhár ask whether a similar phenomenon can be observed when a $(2:2)$ game is played on $G_{n,p}$. We prove that this is not the case, and determine the threshold probability for winning this game to be of size $n^{-2/3+o(1)}$.
Linear Compactness and Combinatorial Bialgebras
Authors: Marberg Eric
Published: July 2021

We present an expository overview of the monoidal structures in the category of linearly compact vector spaces. Bimonoids in this category are the natural duals of infinite-dimensional bialgebras. We classify the relations on words whose equivalence classes generate linearly compact bialgebras under shifted shuffling and deconcatenation. We also extend some of the theory of combinatorial Hopf algebras to bialgebras that are not connected or of finite graded dimension. Finally, we discuss several examples of quasi-symmetric functions, not necessarily of bounded degree, that may be constructed via terminal properties of combinatorial bialgebras.
On Automorphisms of Direct Products of Cayley Graphs on Abelian Groups
Authors: Morris Dave Witte
Published: July 2021

Let $X$ and $Y$ be connected Cayley graphs on abelian groups, such that no two distinct vertices of $X$ have exactly the same neighbours, and the same is true about $Y$. We show that if the number of vertices of $X$ is relatively prime to the number of vertices of $Y$, then the direct product $X \times Y$ has only the obvious automorphisms (namely, the ones that come from automorphisms of its factors $X$ and $Y$). This was not previously known even in the special case where $Y = K_2$ has only two vertices. The proof of this special case is short and elementary. The general case follows from the special case by standard arguments.
A Discrete Morse Perspective on Knot Projections and a Generalised Clock Theorem
Authors: Celoria Daniele , Yerolemou Naya
Published: July 2021

We obtain a simple and complete characterisation of which matchings on the Tait graph of a knot diagram induce a discrete Morse function (dMf) on the two sphere, extending a construction due to Cohen. We show these dMfs are in bijection with certain rooted spanning forests in the Tait graph. We use this to count the number of such dMfs with a closed formula involving the graph Laplacian. We then simultaneously generalise Kauffman's Clock Theorem and Kenyon-Propp-Wilson's correspondence in two different directions; we first prove that the image of the correspondence induces a bijection on perfect dMfs, then we show that all perfect matchings, subject to an admissibility condition, are related by a finite sequence of click and clock moves. Finally, we study and compare the matching and discrete Morse complexes associated to the Tait graph, in terms of partial Kauffman states, and provide some computations.
Can Learning Objects Help Student-Teachers Become Self-Regulated Learners?
Authors: Delgado Alvarado Natanael
Published: July 2021

This paper describes how an original resource set of learning objects was developed to foster learning to learn (Gargallo Lopez et al., 2020) among student-teachers and how these interactive online materials are planned to be effectively incorporated into an intervention. Such implementation follows an innovative pedagogical framework based on a sociocognitive view of self-regulated learning (SRL) and the integrative learning technologies (ILT) approach to technology. The full project, starting in August 2021, proposes the independent use of the resource set of learning objects as a starting point to assist student-teachers with the development of self-regulated learning in their English courses under this new framework.
Advanced data on stratigraphy and lithology of Mio-Pliocene sediments of North Absheron folded zone of western border of South Caspian

Published: July 2021

North Absheron folded zone is closely located to Turan plate and separated from Turkmenbashy-Predcaucasus deep fault. However, North Absheron folded zone has a complicated geological structure; local structures here are of platform character, unlike in the west and north-west part of the region, where formation of the sediments of Mio-Pliocene and Cretaceous-Paleogene stages became significantly complicated due to the high hypsometric state of the surface of Mesozoic folding and the increase of regional and interstratified washaways and bracits as well. The paper specifies the stratigraphy of Mio-Pliocene stages within the west part of the region in the structures of Absheron group, Agburun-deniz and Iki-gardash, marking the absence of the sediments of lower part of Productive Series. Due to the new findings of mactra fauna, the washaway of significant part of the Upper Miocene (Pontian, Miotice and Upper Sarmatian) has been justified. According to the fauna remains and the mineralogical-petrographic composition of Absheron group rocks, only Sarmatian and Chokrak sediments from the Miocene stage outcrop in the sections of deep wells, which unconformable occur in the aleurite-clay series of Maikop stage. The Lower Pliocene in West Absheron structure appear only in a short volume – Balakhany suite occurring in the monomict quartz sandstones of fluvial-distributary origin. Grey Miocene series appear with the alternation of units of polymict sandstones and grey hydromicaceous-kaolinite clay with interlayers of cement stones. Maikop series appear in short extent and occur in polimict aleurites and brown-grey clays including calcite-siderite concretion.

Published: July 2021

The development and implementation of technologies of impact on nanosize phenomenon in oil-gas fields enables to significantly increase the percentage of extraction of hydrocarbons from the resources. The future of oil-gas sphere is associated namely with the nanotechnologies. Therefore, the task of adequate consideration of nanophenomenon in oil-gas reservoirs and their control is essential in the oil-gas sphere. The tasks in petroleum science cannot be performed without creative interaction of the scientists from physics, chemistry and mathematics, metal physicists, biologists, i.e. the whole science community. It should change conservative world view of the managers in oil-gas sphere, old scientific schools and saturate the field with already wellknown and innovative nanotechnologies.

Published: July 2021

The paper deals with the methods of preparation of crude oil samples and chromatographic analysis of petroleum hydrocarbons (alkanes, monoaromatic compounds, policyclic aromatic compounds), as well as the results of the analysis (chromatograms of the samples and concentrates of hydrocarbons). The analysis have been carried out on Shimadzu GC 2010-plus and PEGASUS 4D GCxGC TOF-MS chromatographs. In the analysis of alkanes, monoaromatic and policyclic aromatic compounds the column temperature comprised 60−330 оС, 40−120 оС and 70−300 оС correspondingly. Silicagel of 100−200 mehs size was used as a sorbent. Developed methods may be applied for the analytical purposes in petrochemistry and corresponding scientific research surveys as well.

Chilov adasy field is being in industrial operation since 1948. The oil content is associated with Kirmaki, Gala, Lower Kirmaki, Upper Kirmaki sand suites of the deposits of lower section of Productive Series. The oil potential in Chilov field is distributed both on lower and upper wings of the structure which is characterized with the fault of 400-500 m amplitude. The difference is the oil bearing capacity in the lower wing is associated with Kirmaki, Gala, Lower Kirmaki, Upper Kirmaki sand suites while in the upper wing it is connected with only Gala and Lower Kirmaki suites. The first 10 t oil production was obtained on 04.06.1974 in the well No 49 of Upper Kirmaki clay suite in the interval of 647–644 m. Afterwards, despite of oil output from 3 more wells (No 29, 83, 163), the distribution of oil content in Upper Kirmaki clay suite along the field was not clear and the reserves not calculated. Thus, due to the fundamental analysis of field-geophysical data of the wells in Upper Kirmaki clay suite and consideration of test results it was defined that it has commercial oil reserves. The distribution of oil reserves within the blocks of Upper Kirmaki clay suite structure has been specified and the borders defined as well.
On perspectives of additional exploration of oil and gascondensate reservoirs in kenizdagh area
Authors: Hasanov V.T.
Published: July 2021

The paper studies the features and exploration state of oil and gascondensate deposits of VII horizon of Productive Series in Kenizdagh field based on the actual data. The oil deposit was discovered in1930 in the north-east part of the south-east pericline of the fold and gascondensate field - in the south-west part of the same pericline and they seperate from each other with the fault. Both fields border on the pinchout line of sand layers of the horizon from northern and eastern parts. The results of test intervals justify that oil and gas was produced from the sand layer VIIa in the lower part of VII horizon. The reason for water obtaining from the wells with positive logging of the horizon is that the horizon was tested together with the watered layers above VIIa horizon and at the same time – the failure of casing string. The drilling of new wells is offered with the purpose of exploitation of recoverable hydrocarbon resources and completing the exploration.
