Published: June 2022

Conjecture will always be used by learners in problem solving, because the conjecture itself is tied to activities such as logical reasoning, translating problems, analyzing and evaluating an information to obtain valid decisions related to problem solving, where the conjecture is also able to develop the learning process of the learner in making a statement, especially with the help of open problems in its application,  Which can make learners morecreative. This research aims to illustrate the conjecture ability of learners in open-ended problems with descriptive types of research and qualitative approaches  to number pattern material, especially generalizing patterns. The subjects of the study are four learners who have a high and moderate level of mathematical ability and are willing to take part in interviews. The results showed that  all subjects have not been able to perform every stage on constructing the conjecture, especially in the stage of arguing the conjecture and there is one subject who does not do the stage of proof of the conjecture because it is confident in the formula that has been given by the teacher. So that learning activities are needed in which there is problem solving that collects the ability of learners' contours,  open-ended problems can also be one of the problem choices that can help students build their thought processes independently, and not bound by the formula of teachers or books.

Mathematical ability is the ability required by students to solve a problem, students with high abilities will find it easy to solve problems because they have a good understanding of concepts, whereas students with low abilities will find it difficult to solve problems because they do not understand concepts correctly, which is what causes students to make conceptual errors. A condition when students experience a conceptual error is called a misconception. This research is a qualitative study that has the purpose to describe the misconceptions at each level, such as high mathematical ability, moderate mathematical ability, and low mathematical ability on quadrilateral material and alternatives to overcome them. The subjects in this study were 3 students who were selected using purposive sampling.  In this study, students were given a mathematical ability test so that they could be grouped according to their level, then misconceptions were analyzed using a misconception test with the modified CRI method and continued with a diagnostic interview. The results showed that students with low mathematical abilities experienced more misconceptions than other abilities. The three subjects experienced misconceptions in determining the shapes which include rectangular shapes and the nature of rectangular. The causes of misconceptions are caused by pictures, students' abilities, and incomplete reasoning. The alternatives that can be done to overcome misconceptions are providing cognitive conflict, providing scaffolding, and re-explanation.

Tujuan penelitian ini adalah untuk menggambarkan proses berpikir kritis siswa SMA dalam memecahkan masalah matematika ditinjau dari gaya kognitif reflektif dan impulsif. Penelitian ini merupakan penelitian deskriptif dengan pendekatan kualitatif. Subjek penelitian ini terdiri dari dua orang siswa kelas X yang memiliki gaya kognitif reflektif dan gaya kognitif impulsif dengan kemampuan matematika setara. Hasil penelitian ini menunjukkan bahwa siswa dengan gaya kognitif reflektif melewati 4 tahap proses dari berpikir kritis yaitu Pengenalan, Analisis, Evaluasi, dan Memikirkan Alternatif Penyelesaian. Soal dipecahkan siswa dengan langkah-langkah yang sistematis, rinci, cermat, dan jelas meskipun waktu yang dibutuhkan cenderung lama. Pada tahap Evaluasi dan Memikirkan Alternatif Penyelesaian, siswa kembali memeriksa jawaban secara teliti dan memikirkan alternatif jawaban yang lain meskipun ketika mencobanya, masih belum sampai pada hasil akhir. Sedangkan siswa bergaya kognitif impulsif hanya melalui 2 proses berpikir kritis, yaitu Pengenalan, dan Analisis. Siswa memecahkan soal dengan langkah-langkah singkat, kurang jelas, tidak beralasan logis, meskipun waktu yang dibutuhkan cenderung cepat. Pada tahap Evaluasi dan Memikirkan alternatif penyelesaian, siswa tidak berpikir untuk memeriksa kembali atau memikirkan cara lain untuk menyelesaikan soal.

Privatization is one of the Government's efforts to obtain additional capital with one of the goals for the efficiency of BUMN. The efficiency of BUMN due to privatization needs to be studied through data processed using a statistical approach. Based on the results of the study, it can be seen that BUMN is relatively more efficient before privatization compared to after privatization, then it is found that from the tested variables, there are 3 factors that affect the efficiency of construction BUMN, namely total assets, economic growth and interest rate. Privatization has no effect on the efficiency of Construction SOEs. This shows that the privatization carried out has no effect on the company's performance. This can happen because the shares sold to the public are relatively small. The government is still dominant as a shareholder, so management control from the government is still dominant.DOI: https://doi.org/10.26905/afr.v4i2.6234

Analysis of Volatility Spillover in African Stock Markets: Evidence from Nigeria, Ghana, and South Africa
Authors: Ali Peter
Published: June 2022

The purpose of this paper was to analyze stock market return volatility spillover between in Sub-Sahara markets using Nigeria, Ghana and South Africa monthly data from January 2000 to December 2017. Preliminary analyses from descriptive statistics show that show mean monthly returns are positive for all the stock markets. Skewness coefficients show that the stock returns and interest rates distribution of all Sub-Sahara Africa stock markets are negatively skewed but inflation rate is positively skewed for Nigeria and South Africa, and flat for Ghana. Excess kurtoses are positive for all the stock markets and macroeconomic indicators, and Jarque-Bera statistics indicate the stock markets’ series and macroeconomic indicators are not normally distributed. The Unit roots tests results indicate that all the stock markets and macroeconomic indicators are first difference stationary. The results of multivariate BEKK-GARCH (1,1) model show evidence of volatility spillover in Sub-Sahara Africa stock markets. We therefore recommend amongst others that stock market authorities should formulate and implement policies that would mitigate any negative effect of stock return volatility on the wealth of retail investors so as to sustain investors’ confidence in the African stock markets. This will eliminate the destabilising impact on the investors’ confidence on the markets.

Along with the increasing need for residents to find jobs that provide better income in the city, this has had an impact on increasing the need for housing. On the one hand, the availability of affordable land and housing is a problem for the urban population explosion. For this reason, the effort to build flats is a priority for housing procurement, considering the large number of residents who need a place to live. With consideration of affordable prices, the construction of flats for middle-class residents while still paying attention to the standardization of decent, healthy, and comfortable housing. Law No. 20 of 2011 concerning Flats (UU Rumah Susun) in Article 24 explains that the construction of flats must comply with technical and administrative provisions and UUPK concerning the rights of residents buying flats to obtain a certificate which must be fulfilled according to the agreed agreement. The problem that occurs is that in fact, the flats are commercial in nature, both in the form of flats and apartments in several areas, many of which the owners have not yet obtained a certificate of ownership of the flats. With regard to this fact, after the flats are sold and bought by the public, the buyer is entitled to the part that has been sold, and the developer cannot own it.How to cite item: Binsneyder, M Oktarina, NF (2022).

The filing of a lawsuit to the court must meet the formal requirements of the lawsuit, including the plaintiff and the defendant must be complete based on a legal relationship and based on the fact that the party in control or the party claiming to have a right to an object must also be sued. The incompleteness of the parties in a lawsuit can cause the lawsuit to be declared lacking parties so that the lawsuit can be declared unacceptable. However, for a lawsuit based on a deed made before a notary where the position of the notary in a lawsuit is very dependent on the arguments of the lawsuit filed by the plaintiff. The problem to be raised is whether the notary has a legal relationship with the parties who made the deed, or does the notary have a legal obligation to be responsible if one of the parties making the deed suffers a loss? This writing uses a normative method. The results and discussion show that the position of the notary as a party to a lawsuit based on the deed he made must pay attention to the basis or argument of the lawsuit such as default, or cancellation due to false information, or acts against the law. Thus, it can be said that a lawsuit based on a deed made by a notary where the notary is not included as a co-defendant does not necessarily mean that the plaintiff's claim can be declared lacking parties so that the lawsuit is NO.How to cite item: I.

Published: June 2022

The conception of potato genotype specificity response to in vitro conditions forces us to optimize the cultivation conditions for each variety for microtuberization (MTB) method seed production. Zoned varieties, based on the similarity of field conditions requirements, could be cultivated on standardized media with the achievement of a sufficient average MTB efficiency. The morphometric parameters dynamics (7-62 days) of microplants from the collection of cultivars, widely cultivated in the Krasnoyarsk Territory, were studied on Murashige-Skoog media, containing MTB inductors: sucrose (80 g/L) (M0) and phytohormones in addition: kinetin (1 mg/L) (M1) or a combination of kinetin (2 mg/L), adenine, IAA (1.5 mg/L each) (M2). Hormone- free medium with 30 g/L sucrose was used as control. No inducing effect was detected of phytohormones on MTB frequency and process dynamic of investigated cultivars, except Red Scarlett, under sucrose concentration, had been used in the present study. The determining factor inducing MTB was a high level of sucrose (80 g/L). The phytohormones influence was manifested in the differences in the varietie`s growth parameters. Root systems of domestic cultivars Antonina, Charoit, Hozjajushka were completely developed by 28 days on all media. Close values of the shoot height and the internodes number on M0-M2 media during most of the cultivation period were detected. Meteor, Rosara, and especially Red Scarlett cultivars were distinguished by a decrease in growth parameters in the line of conditions Control> M0> M1> M2. Cultivars groups, marked in vitro, differ by the habitus of plants formed by cultivars under the field conditions. The first three cultivars are tall plants with large leaves, the second group consists of intermediate type plants. However, we can already speak, based on data on growth inhibition, about the advantage of media with phytohormones for cultivars with the same habit as the second group has. Such reaction may be indirect evidence of the redistribution of assimilates in favor of MTB.

The article presents materials on identifying possible changes in oil-bearing and oil-polluted soils of Absheron peninsula using satellite data and GIS technologies. The state of degraded soils polluted with oil and oily wastes, was analyzed as well as in the territories of Absheron peninsula where in 2014, 2017 and 2020 recreational activities were carried out. Multispectral images of the landsat-8 satellite were used to detect changes in these territories. The received primary results were mapped and comparatively analyzed. On the basis of the comparative analysis the changes occurred in this territory were analyzed every 3 years. In order to detect the changes, the new mathematical formulas have been developed and applied to the indicated spectra. The received results have been presented in the form of relevant maps, tables and graphs.
The main aspects of the development of structural and technological devices made of modern domestic materials to ensure the safe operation of water intakes of reclamation systems
Authors: Khetsuriani Yelguja Demurovich , Vasiliev Sergey Mikhailovich
Published: June 2022

In the article, in order to solve various design problems of the hydraulic engineering and reclamation class, taking into account the conditions of functional operation of soft floating structures as water intake structures, the main aspects of the development of protective devices for irrigation water are formulated. As a result of the conducted research, based on the experience of designing water intake structures with water treatment systems, a specialized algorithm for solving problems of creating constructive and technological developments  for reclamation water intakes in the water management complex was developed. The obtained results of the design and inventive tasks for a soft surfaced structure used as a water intake structure make it possible to select the estimated irrigation water costs (Q, m?/s) in the required quality and quantity and ensure the environmental safety of the reclamation system. In order to solve the tasks of ensuring the environmental safety of the reclamation system, the entire complex of structural structures, protective devices and technological equipment included in the water management complex was divided into three interconnected structural and technological schemes as part of a specialized type of natural-technical system “Water object – Water intake structures – Meliorative system”. Soft surfaced biopositive structures of a water intake structure as part of a reclamation system have been developed, in which the main protective agent is the first proposed by the author for the purification of irrigation water – a ruff filtrating load, which is an environmentally safe means of protecting the reclamation system from mechanical and biological contamination. An economic and mathematical model of a specialized type of natural-technical system “Water object – Water intake structures – Meliorative system”is presented, which represents the final stage of ensuring environmental safety of reclamation water intake, which is the main factor in increasing soil fertility and, accordingly, economic efficiency in the whole agricultural complex.
Stabilization clause as a legal means and reception of legal technique
Authors: Usenkov Ivan
Published: June 2022

The article examines the stabilization clause – its essence and significance for the stability of legislation, reform and extension to legislative branches and institutions. It is concluded that the stabilization clause is both a legal means and a method of legal technique, with the help of which a person is provided with guarantees of non-application of unfavorable changes in national legislation to him. It is indicated that the stabilization clauses in Russia today apply to a fairly wide range of regulations, but it is believed that it is possible to expand their range to norms providing for legal liability. The stabilization clause is not directly related to the stability of legislation, but it can influence it in various forms, as well as compensate for the instability of legislation.

Nidificación del halcón serlvático de collar (Micrastur semitorquatus) en un complejo arqueológico en el estado de Campeche, México
Authors: Monter-Pozos Alvaro , Hernández-Hernández Julio C.
Published: June 2022

El halcón selvático de collar (Micrastur semitorquatus) es el miembro más grande de su género. Se encuentra en una amplia variedad de hábitats desde el centro de México hasta el sur de Brasil. Registramos un nido de M. semitorquatus dentro de una de las estructuras que conforman el complejo arqueológico de Xkipché, en el estado de Campeche, México. Encontramos el nido a nivel del suelo, lo que representa el primer registro en México. En el interior del nido observamos restos de una iguana negra (Ctenosaura similis), plumas de la chara yucateca (Cyanocorax yucatanicus) y del momoto cejas azules (Eumomota superciliosa). Se ha mencionado que la anidación de esta especie en construcciones humanas es un comportamiento adaptativo en la búsqueda de lugares de anidación debido a la pérdida de hábitat, aunque también puede deberse a la flexibilidad de la especie. La información aquí presentada da pauta para futuros estudios en la zona, teniendo en cuenta que la fragmentación y la pérdida del hábitat causadas por la actividad humana condicionan la supervivencia para esta y otras especies.
