Based on the Directorate Report General's Horticulture, the contribution of vegetable horticulture agriculture tends to increase, where the GDP of vegetable horticulture has increased by 9.86%. In 2016, cabbage is a vegetable horticultural commodity that has the highest production amount in Indonesia, and the poor district is one of the major producers of commodities cabbage in eastern Java. Generalized Space-Time Autoregressive (GSTAR) is a multivariate time series model that considers site aspects with heterogeneous location characteristics. The purpose of this study was to model cabbage production in Malang Regency using the GSTAR model. Selection criteria for the best model to use the value of the root mean square error (RMSE) and the value of R The results showed that the GSTAR model (1,2) is the best model for modeling cabbage production and has good forecasting accuracy to predict cabbage production in Malang Regency.

Reasoning ability encourages students to think logically, so it is a very important part in learning process. This qualitative descriptive study aims to determine the mathematical reasoning ability of Junior High School students in solving non-routine problems of the two-variable linear equation systems material. The subjects were 6 students of class VIII.7 SMP Negeri 17 Palembang. Due to Covid-19, the research was conducted online using test and interviews, and analyzed descriptively. The results showed that of the 7 indicators of mathematical reasoning ability used, high-capable subjects fulfill almost all indicators. Indicators are not fulfilled in namely posing an assumption, perform mathematical manipulation, draw conclusions, compile evidence, provide reasons or evidence for the correctness of the solution to problem 1 and find patterns or properties of mathematical phenomena that will be generalized to problem 2. Indicators that are not fulfilled in medium-capable are perform mathematical manipulation, draw conclusions, compile evidence, provide reasons or evidence for the correctness of the solution and find patterns or properties of mathematical phenomena that will be generalized to problem 2. Students with low-capable still not dominant and only permit indicators to present oral, written, picture and diagram math statement and draw conclusions from those statements.

Learning during the pandemic presents a major challenge for mathematics teachers. In this condition, Teacher must examine effective mathematical teaching practices that support each and every student to develop a deep understanding of mathematics; and developing a positive mathematical identity and strong sense of mathematical agency. This paper discusses how do the eight effective mathematics teaching practices support key mathematical practices essential for students to develop to be successful in mathematics. It has been important to support both preservice and inservice teachers in implementing effective teaching practices by providing opportunities for collaboration and planning, resources for teaching and learning mathematics in new settings, professional development on use of new technologies, ways of addressing effective practices in varied environments, and support in identifying mathematical tasks that would support student development of essential mathematical practices and ensure equitable access to high quality learning

In this work, a deterministic mathematical model of schistosomiasis transmission dynamics is discussed. In rural areas, many people work as a cattle farmer. Cattle farmers in endemic areas are very susceptible to schistosoma worm infection. To study the dynamics of schistosomiasis spread in traditional cattle farmer communities, we develop a mathematical model by considering human, cattle, and snail population as well as parasite density in environment. The model is expressed as a system of first order differential equations. Firstly, we verify the non-negativity and boundedness of the solutions of the model. After determining the equilibrium points of the system, we determine the basic reproduction number. Linearization and Routh Hurwitz condition are used to analyze the local stability condition of the disease free equilibrium point. Center manifold theory is used to study the local stability condition of the endemic equilibrium point. We prove global stability condition of the disease free equilibrium point by formulating suitable Lyapunov function and using LaSalle invariance principle. Several numerical simulations are presented. Our results show that the farmer should keep the cattle, water, and food clean. In addition, the farmer should use molluscicide in their farm area and give schistosomiasis drug to the cattle, regularly.

This research aims to describe the impact of using a single image in representation on understanding the concept of fractions. The subjects in this study were six students in grades 4-7. The data collection technique used in this research is interviews conducted on research subjects one by one. Students' limitations in understanding the concept of fractions are caused by using a single image in the representation so that students had difficulty dealing with two aspects of the image in the representation, namely the difference in size and shape. The results showed that in comparing two fractions originating from a circle of different sizes, students predominantly assume that the fraction from the largest slice of the circle is the fraction that has the greatest value. There are still students who cannot state a fraction of a part that has a different way of dividing from what they usually encounter. There are still students who are affected that two parts with different shapes have different areas even though the two parts come from a flat building with the same size.

This study aims to analyze the misconceptions experienced by students in exponential material. This research was conducted in Class X IPA 1 SMAN 4 Makassar in the odd semester 2019/2020 academic year. The subjects in this study were three students who were selected based on the type of misconception. This type of research is descriptive qualitative research. The instruments used were diagnostic tests and interview guides. This study analyzed the types of students' misconceptions, namely, classification misconceptions, correlational misconceptions, and theoretical misconceptions. The results of this study indicate that of the three subjects who experience a classification misconception caused by a lack of understanding of mathematical symbols, they rarely ask the teacher. Correlational misconceptions caused by the lack of variety in the questions being worked on, lazy to repeat learning at home. Meanwhile, theoretical misconceptions are caused by a lack of practice in doing questions, embarrassed to ask the

It is an important task for an actuary in determining an appropriate premium price for each customer with different risks and characteristics. The purpose of this study is to determine the best model for pure general insurance premiums and variables that can affect the amount of pure premiums. One of statistical analyzes that can be used to model insurance premiums is Generalized Linear Models (GLM). GLM is an extension of the classic regression model that can accommodate the flexibility of its users to use multiple data distributions, but is limited to the exponential family distribution. In the GLM model the premium is obtained by multiplying the conditional expected value from frequency of claims and cost of claims. Based on the research that has been done, it is found that frequency of claims follows the Poisson distribution. Meanwhile, cost of claim follows the Normal distribution. From the two models, it is found that the variables that affect the pure premium are the type of work, the reason for the claim, the location of residence, the marital status and the class of the customer's vehicle. It indicates that the GLM model is a representative model and useful for the insurance company business.

This study aims to analyse the skills to understand mathematical concepts in the Probability Theory subject. As a scientific discipline, Probability Theory is one of the statistics study program subjects that require mathematical skills to learn. One of the skills needed for learning is the skill of understanding mathematical concepts. The analysis of skills in understanding mathematical concepts in the Probability Theory course shows that students still have difficulty checking the truth and writing the concepts used in each discussion of the material. This is one of the factors that make students' skills to understand mathematical concepts not good. Based on this research, it appears that students' mathematical understanding skills in the Probability Theory course are still lacking. Understanding the concept of statistics is not currently apparent in students when studying the Probability Theory. They have not been able to optimize all their mathematical abilities in learning, so they tend to give up on doing tasks when experiencing difficulties. This research is expected to be a reference and discourse for practitioners of mathematics education to improve the ability to understand the basic concepts of Probability Theory.
