Abstract

The role of learning media in the learning and teaching process is an integral part of the world of education. The development of technology-based learning media in the field of mathematics has a great influence on students' level of understanding. 3D printing technology can stimulate teacher interest and creativity in creating learning media prototype objects. The aim of implementing this activity is to increase the knowledge and skills of Parepare City Mathematics Teachers in creating innovative technology-based spatial mathematics learning media which is able to increase students' interest in learning the material thereby improving student learning outcomes. Implementation methods include observation, discussion, lectures and practicum. The activities were carried out in several training series. Technology optimization training on innovation in learning media development, training and assistance on the use of Ultimaker cura software on mathematics learning media, and training and assistance on 3D printing machines as mathematics learning media. The results of this activity were an increase in understanding of learning media concepts from 37.5% to 92.5%. Partners have understood and are able to sketch three-dimensional learning media using the ultimaker cura software, this is indicated by the existence of new knowledge about the software from not knowing to being able to operate which has increased by up to 82.5%, partners understand and are able to operate the devices on the 3D Printing machine to produce three- dimensional learning media that are suitable for use and this is proven by the survey figures for increasing knowledge by up to 87.5% and the ability of partners to color learning media which has increased by up to 87.5%. The survey results show that after the training and mentoring activities, knowledge and skills have increased significantly. The conclusion from the implementation of this activity is that training participants have been able to create innovative learning media that can increase students' enthusiasm for learning so that there is an increase in student learning outcomes.

Abstract

The low level of numeracy literacy among elementary school students in Indonesia poses a significant challenge in mathematics education, as reflected in the 2018 PISA results. This gap is exacerbated by conventional teaching methods that lack concrete media and interactive approaches, making it difficult for students to grasp fundamental concepts. Mathematics anxiety further undermines students’ motivation and learning outcomes. An enjoyable and communicative learning approach is therefore needed to enhance students’ understanding of numeracy concepts effectively and sustainably. This activity aimed to improve the numeracy literacy of fourth-grade students at SD Negeri 4 Parepare through the implementation of the interactive and engaging GASING method, which is easily applicable by teachers in the classroom. The program was carried out in three stages—preparation, implementation, and evaluation—involving 40 fourth-grade students. Activities such as Lari Balon (Balloon Run), Matematika Berantai (Chain Mathematics), and Mathematical Crosswords enhanced students’ motivation, concentration, and teamwork. Evaluation results indicated improved arithmetic skills and understanding of basic mathematical concepts. The Kartini group achieved the highest score with a total of 247 points. Feedback from teachers and students highlighted that the GASING method made learning more enjoyable, reduced mathematics anxiety, and encouraged active student participation. The GASING method proved effective in improving students’ numeracy literacy through a game-based, enjoyable learning approach and is suitable for implementation in other elementary schools.

Abstract

Poverty is a complex social issue that requires in-depth analysis to identify its contributing factors. South Sulawesi, as one of the provinces in Indonesia, continues to face various challenges in poverty alleviation. This study is a quantitative research that aims to model the poverty rate and poverty severity index using a biresponse nonparametric kernel regression with the Nadaraya-Watson estimator and Gaussian kernel function. The analysis is based on 2024 data form the Central Bureau of Statistics (BPS), which includes poverty indicators as response variables and socio-economic factors, processed using R Studio 2025. The nonparametric biresponse kernel regression analysis yielded optimal bandwidths of h_1=0,188; h_2=0,083; h_3=0,159; and h_4=0,028. Model accuracy is demonstrated by a Generalized Cross-Validation (GCV) value of 5.515 and a Mean Squared Error (MSE) of 0.585, indicating high stability and low prediction error. The model demonstrates adaptive accuracy in simultaneously modeling the two response variables and highlights the strength of kernel-based biresponse regression as an evidence-based tool for policymakers to design targeted, region-specific poverty alleviation strategies.

Abstract

Sharia banks act as financial institutions that perform financial intermediary functions, connecting parties with excess funds with parties in need of funds. The pandemic era in early 2020 is one of the most striking examples that shows the serious impact of macroeconomic changes on Islamic banking in Indonesia. This study focuses on the performance of Islamic banking. It aims to analyze changes in four variables: number of branches, number of human resources, outstanding financing, and Non-Forming Finance in Islamic banks, both before and during the pandemic. The method used is a statistical approach sourced from secondary data published by the OJK, which includes a sample of 12 Islamic commercial banks and 21 Islamic business units. The analysis technique used is a descriptive comparative analysis of the results of the Mann-Whitney statistical test. The results of this study, based on the analysis using the Mann-Whitney test, indicate significant differences in these variables between the periods before and during the COVID-19 pandemic in the Islamic banking sector. Therefore, a strategic response is needed from the Islamic banking sector in addressing changes in the economic situation and customer behavior influenced by external factors such as the pandemic. The importance of adaptation by the Islamic banking sector in facing a pandemic, as well as the importance of better risk management in managing business growth and credit risk.
