Abstract

This study aims to analyze the problem-solving abilities of tenth-grade students at SMAN 1 Lalolae on the topic of exponents after the implementation of problem-based learning (PBL) with reference to Polya’s problem-solving stages. The background of this research is based on the limited number of studies that specifically examine students’ problem-solving skills in exponents through the application of PBL with a Polya-based approach. The research employed a descriptive qualitative method with ten students from SMAN 1 Lalolae selected using purposive sampling, representing high, medium, and low ability categories. Data were collected through problem-solving tasks on exponents and semi-structured interviews, then analyzed using Polya’s indicators, which include understanding the problem, devising a plan, carrying out the plan, and reviewing the solution. The findings indicate that high-ability students were able to solve problems systematically from understanding the problem to obtaining the correct solution, although the evaluation stage was not yet optimal. Medium-ability students were able to write down information and formulas but often struggled in selecting appropriate strategies, resulting in partially incorrect answers. Meanwhile, low-ability students encountered difficulties from the initial stage, demonstrated unclear strategies, and produced incorrect solutions.  The findings suggest the need to develop scaffolding strategies to support students with moderate and low levels of ability. The application of PBL was proven to enhance students’ engagement and problem-solving abilities, although evaluation and reflection aspects still need improvement.

Abstract

Economic growth serves as a key factor in analyzing the economic conditions of a country or region. The secondary panel data used in this study consists of a combination of cross-sectional data from five regencies/cities in East Nusa Tenggara (NTT) that were most affected by the COVID-19 pandemic. This time-series data spans from 2018 to 2023 and is split into three phases: the period before the pandemic, the pandemic period, and the post-pandemic period.This study aims to analyze the factors influencing economic growth in NTT Province during the pre-, during-, and the period after the pandemic. The research employs the Fixed Effect Model (FEM) with Gross Regional Domestic Product (GRDP) as the dependent variable. The independent variables include the Regional Minimum Wage (UMR), Per Capita Expenditure, Labor Force Participation Rate (TPAK), and Domestic Investment (PMDN). The research findings indicate that the variables that significantly influence economic growth in NTT Province are the Regional Minimum Wage and Per Capita Expenditure. The Regional Minimum Wage has a negative impact on economic growth, whereas Per Capita Expenditure has a positive impact. This means that an increase in the Regional Minimum Wage will decrease economic growth, while an increase in Per Capita Expenditure will enhance economic growth.

Abstract

Dalam aljabar max-plus, matriks normal didefinisikan sebagai matriks persegi  dimana elemen pada diagonal utamanya adalah nol dan elemen non diagonal utamanya adalah bilangan real non positif. Struktur ini memberikan sifat keteraturan khusus terhadap operasi maksimum dan penjumlahan pada aljabar maxplus. Pada artikel ini akan di bahas review tentang matriks  normal dan perilaku stabil terhadap perpangkatan, termasuk kondisi tertentu yang menjamin sifat idempoten. Selain itu, diperoleh kriteria struktural yang memastikan kekomutatifan dua matriks normal terhadap perkalian max-plus.
