In this paper, we introduce about intuitionistic anti fuzzy vector spaces with respect to t-norm and t-conorm (IAFVSTC). We discuss some properties of IAFVSTC. We investigate IAFVSTC together with characteristic function intuitionistic fuzzy sets (IFS). We obtain properties of some operation and relation between IAFVSTC, and submodule of R-module which the IFS is an IAFVSTC.

This study is purposed to determine the student's conceptual understanding and learning self-reliance in New Normal era assisted by Photomath on SLETV materials. This study implements quantitative approach of quasiexperimental design and One Group Pre test-Post test Design. The population of this study is all 7th grade students in SMPN 3 Jeumpa, Bireuen. The sample is selected using purposive sampling, they are 29 of 7th grade students in SMPN 3 Jeumpa, Bireuen who attend when this study is conducted. The instrument adopted to measure the student’s understanding level is a test. Meanwhile, to determine the student’s learning self-reliance, this study uses questionnaire. N-Gain is calculated to know the student’s conceptual understanding level, and the percentage technique is also applied to determine the student’s self-reliance level. The research findings show that teaching and learning process assisted by Photomath on SLETV materials can improve the student’s conceptual understanding, although the improvement is still considered in the low category. Besides, the improvement of the student’s conceptual understanding achieves the middle category. Additionally, 80% students agree that Photomath use can create the students more self-reliant in mathematics teaching and learning process, particularly on SLETV materials.

Climate change in Sumatra island is likely a result of widespread land-use changes by the plantation industry. This study aims to investigate trends in land surface temperatures in Sumatra island. Land surface temperatures from 20012020 were downloaded from the National Aeronautics and Space Administration moderate resolution imaging spectroradiometer Terra satellite and divided into 5 regions and 45 sub-regions spread equally across the island. The statistical method that used to analyzed the data was cubic spline and multiple regression. The seasonal pattern and variation in the land surface temperature were examined using a cubic spline method and the seasonally adjusted land surface temperature was analyzed using a multiple regression model. On average, the land surface temperature on Sumatra island significantly increased over the ten years by 0.076C with a 95% confidence interval of [0.010, 0.141]C.

Stunting is a kind of chronic nutritional problem among under-five years children that characterized by a shorter height compared to other children of their age. The ordinal logistic regression is one statistical method that used to analyze the ordinal response variable with three or more categories and predictor variables that are categorical or continuous. This method has been used in various fields, one of them is in the health field. In this study, ordinal logistic regression is used to describe the correlation between stunting status of children and birth weight, birth length, mother's age, mother's height, mother's knowledge about nutrition, parenting, health services, hygiene and sanitation, number of children and number of family members. The stunting status of children in this study is divided into three kind which are severely stunted, moderately stunted, and normal stunted. The aim of this study is to describe the characteristics of children and to determine the factors that influence the stunting status of children in priority villages for stunting prevention i.e. Bucorwetan and Alaspandan village in the Probolinggo district, East Java, Indonesia. The prevalence of stunting was 30% (22.5% moderately, 7.5% severely). The mother's height and health services were the important determinants of stunting.

Coronavirus is a group of viruses that can cause disease in both humans and animals. The newly discovered coronavirus triggers COVID-19 disease. COVID-19 is now a pandemic that is emerging in many countries around the world, including Indonesia. Several sectors have been affected as a result of this pandemic, such as medical, economics, government, industry, etc. By using ARIMA model, we try to predict the daily cases of COVID-19 that occur in East Java. We obtained this model with the help of R software. The best model we obtained was the ARIMA model (7,1,7), which we used to predict the next 14 days from November 1, 2020, to November 14, 2020. The results of forecasting obtained by comparing real data with a 99% confidence interval, we obtained that the forecasting results are close to the real data that has occurred until November 14, 2020. This prediction is expected to help various sectors affected by this pandemic, such as government, economy, health especially in East Java.

Gedhek, a wall material for Using’s house, which is still used in Banyuwangi, Indonesia. The existence of gedhek in The Banyuwangi Community has never been associated with school knowledge. This makes gedhek known only as objects that are dividing the house (wall). Even though the process of making up to installing gedhek contains various learning concepts, especially mathematics. These mathematical concepts need to be identified through a qualitative research framework. Research data obtained by the method of participatory observation, in-depth interviews, and cultural documentation, then analyzed according to the steps of the ethnographic approach. The results showed that gedhek included mathematical activities, such as: counting, measuring, designing, locating, and explaining.

The average value at risk (AVaR) is a measuring tool used to assess the worst loss experienced by an investor on a portfolio investment at a certain time. Furthermore. AVaR’s level of confidence needs to fulfill all the axioms regarding the nature of risk for risk-varse investors. This is because the possibility of an asymmetric volatility response can be overcomed by estimating the risk of loss using the Glosten. Jagganathan. and Runkle (GJR) models. In this study. the stock price data for the period January 1-28 December 2018 were used for the response. Therefore. this study aims to determine the risk estimation of stock price loss using the Average Value at Risk with the Glosten Jagganathan and Runkle models. The results showed that the stock price obtained from the AVaR estimation with a 95% confidence level of 0.1627% may be experienced one day ahead.

Mathematics is a universal field of science and has a very important role in human life. However, facts in the field show that students’ reasoning power is still weak in the learning process of mathematics. It is because of one of the abstract characteristics of mathematics. This feature causes many students to experience errors in solving math problems. This study aims to analyze students’ errors in solving arithmetic sequences and series material based on Newman’s error analysis in grade VIII Junior High School 11 Jemberin terms of Jung’s personality type. This research is qualitative descriptive research. The subjects in this study were 3 students with introverted personality types. The instrument used in this study was to collect data comprising an MBTI questionnaire, a test regarding the arithmetic sequence and series material, an interview guide and a validation sheet. Based on the research results, introverted students make mistakes in understanding, process skills, and perform mistakes in writing the final answer.

The purpose of this descriptive research was to see the effects of visual-formed problems on junior high school students’ motivation to learn mathematics using a mathematical modeling framework measured using several learning motivation indicators. This research was conducted to 27 students grade VII.2 of SMP Adabiyah Palembang. The questionnaire analysis results showed that the average student learning motivation on mathematics had increased with 51,85% of students having high learning motivation, 48,15% of students having medium motivation, and 0% of students having low motivation.

The left almost semihyperring (LA) is an algebraic hyperstructure satisfying two axioms, these are the left inverse hyperoperation and the distributive axiom between multiplication and addition hyperoperation. In this article, the concept of fuzzy sets is applied to these structures so that we get a new algebraic structure, and it is called fuzzy left almost semihyperring. We show that the set of all fuzzy subsets in LA-semihyperring is also LA-semihyperring. Furthermore, the LA-subsemihyperring and hyperideal fuzzy properties and their relationship to the characteristic function and level set are analyzed.
