Abstract

The purpose of this study was to determine the relationship between high school students' self-efficacy and their ability to solve trigonometric problems. This research is an example of ex post facto correlational research developed using quantitative methodology. All research participants were students of class XG SMA Negeri 8 Pontianak. The method included administering a self-efficacy test and an essay-based assessment of one's ability to solve mathematical problems. The results showed that students' self-efficacy and math problem solving ability were in the moderate range. To determine the relationship between the two variables, data analysis was conducted. The data showed linear correlation and normal distribution. The Pearson Product Moment test was then used to conduct the correlation analysis. The test result is Sig.(2-tailed) < a or 0.034 < 0.05 As a result, it can be said that self-efficacy and math problem-solving aptitude are related. In other words, as students improve in solving math challenges, their self-efficacy will grow.

Abstract

This research aims to describe the mathematical problem-solving abilities of students at SMAN 7 Pontianak regarding story problems in arithmetic sequences, based on the IDEAL stages. The subjects of this study were selected based on their categorization into high, medium, and low ability students. This research employed a descriptive approach with qualitative methods. The instruments used for data collection included problem-solving ability test results and interview sheets.The findings of the study indicate that: (a) subjects with high problem-solving abilities successfully completed all five stages of the IDEAL problem-solving process. (b) subjects with medium problem-solving abilities were able to perform the IDEAL stages, but their results still contained errors. (c) subjects with low problem-solving abilities struggled to complete all five IDEAL stages when solving story problems in arithmetic sequences. Students with lower academic performance were only able to identify problems. They faced difficulties in defining goals and exploring possible strategies, which led to mistakes in the subsequent stages.

Abstract

This research aims to identify significant factors influencing the poverty level in Tuban Regency. Multiple linear regression analysis using the Ordinary Least Squares (OLS) method was applied using the Google Colab platform and the Scikit-learn library to examine the relationship between the Human Development Index (HDI), Open Unemployment Rate (OUR), and Gini ratio on the poverty level. Before the regression analysis was conducted, the data were tested for normality using the Shapiro-Wilk test to ensure that the classical regression assumptions were satisfied. Then, a correlation matrix is presented to provide an initial overview of the relationship between variables. The analysis results show that the HDI is the dominant factor that significantly contributes to the decrease in the poverty level in Tuban Regency. Meanwhile, the unemployment rate and the gini ratio do not show a significant influence in this regression model. Visualization of actual data and model data shows a fairly good fit, indicating the model's accuracy in explaining the variability of the number of poor residents.

Abstract

Let G be a graph that has a vertex set V(G) and an edge set E(G). Let W={w_1,w_2,…w_k} be a subset of V(G). The representation of a vertex v∈V(G) with respect to W, denoted by r(v|W), is defined as k-vector (d(v,w_1 ),d(v,w_2 ), …, d(v,w_k )). A set W is called a local resolving set of G if r(u│W)≠r(v│W) for every two adjacent vertices u,v∈V(G). The smallest cardinality of all local resolving set in G is called the local metric dimension of G, denoted by lmd(G). The local resolving set of G with cardinality lmd⁡(G) is called a local basis of G. In this paper, we determine the local metric dimension of the line graph of generalized Petersen graph P_(n,1).

Abstract

Phubbing is a social problem caused by various factors, one of which is smartphone addiction. This research aims to build a SEAR mathematical model of phubbing problems among adolescents due to smartphone addiction, analyse and simulate the model to predict the number of phubbing cases in Makassar City, and find parameter solutions to this problem. The population in this study consists of adolescents aged 10-14 years in Makassar City, with a sample size of 399 people. The research stages carried out were: building a SEAR model of the phubbing problem, determining the equilibrium point, analysing the stability of the equilibrium point, determining the value of the basic reproduction number , carrying out model simulations using Maple, and interpreting the simulation results. In this paper, it is obtained a SEAR mathematical model for the problem of phubbing; two equilibrium points, namely the phubbing-free and the phubbing equilibrium point; stability of the phubbing-free and phubbing equilibrium point; and the basic reproduction number 3.459 which shows that phubbing cases occur in adolescents with a percentage increase of 1.3% every year. Based on the model simulation, the results obtained show that the parameter solutions in the form of applying the 3S values can reduce the rate of phubbing due to smartphone addiction among adolescents in Makassar City.

Abstract

People's welfare is basically a condition whose form is dynamic or in other words its quantitative value will never stop because it will continue to change along with the development of human life needs. In the Regional Medium Term Development Plan (RPJMD) of North Sumatra Province, the government is trying to realize an advanced and prosperous community life. Law No. 11 of 2019 article 3 paragraph 1, it is also written that the purpose of administering social welfare is to increase the level of welfare, quality and survival. As according to the Central Statistics Agency for North Sumatra in 2021 regarding indicators of people's welfare, namely, population, health, education, employment, household consumption and expenditure, housing and the environment, and participation in social activities. To make a strategy to improve the welfare of the people of North Sumatra, the Government needs to determine which districts or cities are prosperous and which are not. This study uses the spectral clustering method in which this method forms clusters obtained according to data taken at the Central Bureau of Statistics which will be carried out in 2022 data taken in 2021. The results of this study indicate the application of the spectral clustering method for classifying prosperous and less prosperous city districts in North Sumatra province and clusters obtained as many as 2 clusters from data from 33 urban districts in North Sumatra province, namely cluster 1 is a prosperous district or city, namely Medan and Deli Serdang, and cluster 2 is a district or city that is not prosperous, namely, apart from Medan and Deli Serdang.

Abstract

Riset ini berguna untuk mengidentifikasi jenis kesalahan yang diselenggarakan anak didik serta alasan yang menyebabkannya dalam menjawab soal cerita terkait segi empat. Untuk menganalisis kesalahan siswa, digunakan metode NEA. Riset ini bersifat deskriptif melalui pendekatan kualitatif. Data dikumpulkan melalui tes dan wawancara, dengan responden sebanyak 34 anak didik kelas VII E SMP N 4 Tanjung Morawa. Berpatokan analisis data menggunakan metode NEA, ditemukan bahwa kesalahan membaca mencapai 39,70%, kesalahan memahami soal sebesar 41,17%, kesalahan transformasi 22,05%, kesalahan keterampilan proses 38,23%, dan kesalahan menulis jawaban 38,23%. Alasan penyebab kesalahan tersebut meliputi minimnya pemahaman terhadap soal cerita, ketidaktelitian, minimnya bahasa yang dikuasai, kekeliruan konsep, kesukaran dalam melakukan penaksiran, serta kebiasaan yang kurang dalam mencantumkan simpulan dan satuan pada jawaban akhir. Kesimpulannya, banyak anak didik menyelenggarakan kesalahan ketika menulis jawaban, khususnya disebabkan oleh ketidakcermatan dan kurangnya pemahaman konsep.
