Abstract

This study aims to describe the ability of students to solve story problems on the Pythagorean theorem material using structured and systematic stages, namely by doing heuristic learning strategies. The method used is Classroom Action Research (CAR) which is carried out in collaboration with teachers. The CAR design used is the Kemmis and Mc model. Taggart which consists of planning, action, observation and reflection activities. CAR was carried out on class VIII C SMP Superior Al-Yasini Pasuruan. The data analysis technique was carried out descriptively by looking at the percentage of student learning outcomes. In the first cycle, a description of the students' abilities was obtained, but this did not meet the predetermined classical completeness. So that the implementation of the action is carried out based on the reflection of cycle 1. In the second cycle there is a significant increase. Learning outcomes in cycle 1 obtained an average of 78.75, then increased in cycle 2 with an average of 85.67 so that the significant difference between the two cycles is 14.3%. Thus, it can be concluded that the action applied is declared successful and can improve students' ability to solve story problems.

Abstract

The poverty line is the average expenditure to meet the needs of a decent life. The poverty line data of East Nusa Tenggara has increased, due to rice consumption as a major commodity. This forecasting is expected to provide an overview of poverty line in the future and contribute to poverty-related policy making. The data used was 22 data poverty line of East Nusa Tenggara from 2011 to 2021 (Rp/Capita/Month). The data is patterned trend, so this study will compare the double moving average and double exponential smoothing methods to forecast. The data is processed using Zaitun Time Series to get the best method. The comparison of double moving average and double exponential smoothing methods based on the similarities, the level of accuracy, and the differences were the best MAPE, forecasting results, and the efficiency of the method. Based on this comparison, the right method for forecasting the provincial poverty line (MAPE=1.755638) is double moving average. The minimum average expenditure of East Nusa Tenggara to meet the needs of decent living is Rp 443,386.58/capita/month (Mar-22), Rp 454,902.04/capita/month (Sep-22), Rp 466,417.5/capita/month (Mar-23), and Rp 477,932.96/capita/month (Sep-23). Therefore, the government can increase the popularity of local food to decrease the rice consumption.

Abstract

Dedekind Domain and prime ideals are part of the topics discussed in the field of abstract algebra. An integral Domain is said to be the Dedekind Domain if and only if it is a Noetherian, integrally closed, and each of its prime ideals is a maximum ideal. In 2019, Maulana discussed the prime ideal’s properties of Gauss integers. At present, there is no research about prime ideals of specific Dedekind Domain, because of that reason, in this article we will give some prime ideals and prime ideals’ characteristics in the area of the Dedekind Domain Z[x]/<x^2>. In this article, it is found the conclusion I=<x> and I=<k,x> are prime ideals in that Dedekind Domain.

Abstract

Zero-divisor graph is a geometric representation of a commutative ring. Zero-divisor graph of ring R that denoted by TR, defined by a graph whose vertices are all elements of zero-divisor set of a ring R, and two distinct vertices a and b are adjacent if and only if ab=0. In this paper, we will study some of the characterizations of the zero-divisor graph of integers modulo ring ( Zn). This study aims to know some forms of zero-divisor graph of ring (Zn ) and its properties. The method that used in this paper is deductive proof, by taking some example of zero-divisor graph of integer modulo ring ( Zn), then generalized the characterization of example. The firts result is if n=p^2, with p is a odd prime number, then the zero-divisor graph of ring is a complete graph. Then the second result is if n=p1p2, with p1 and p2 are different prime numbers, then the zero-divisor graph of ring is a complete bipartite graph and the diameter is 2.
