    Junior High School Students in Solving Mathematical Ill-Structured Problems: Analyzing Using Harel Theory

    Authors: Shelly Morin, Didi Suryadi, Sufyani Prabawanto, Dedi Sulistiyo

    Abstract

    This study explored how students think when solving ill-structured mathematics problems. This research method was a qualitative case study involving class VIII junior high school students. Data collection techniques were done by giving ill-structured mathematics problems in the form of geometry material, observation, and in-depth interviews. Furthermore, after students solved the problem; to further describe the student’s answers, in-depth interviews were conducted to explore and dig up further information. The results showed that some issues were found: the complexity of the problems given to students became a challenge in solving unstructured geometry problems, students had difficulties interpreting the problem due to limited prior knowledge, especially regarding geometry material, and the problems given required creativity in finding solutions. Students’ constraints were in the lack of prior knowledge, especially geometry materials, and creativity to find and establish strategies to build solutions according to their knowledge. This research contributed to uncovering students’ thought processes when constructing solutions based on their prior knowledge to identify learning difficulties in more depth. This research also showed that the diversity of students’ ways of thinking provides different problem-solving opportunities. © School of Engineering, Taylor’s University.

  • Enhancing Students’ Advanced Mathematical Thinking in Algebra through Three Worlds Journeys on Mathematics Worksheets

    Enhancing Students’ Advanced Mathematical Thinking in Algebra through Three Worlds Journeys on Mathematics Worksheets

    Authors: Nadya Dewinda Agustin, Mohamad Syarif Sumantri, Arita Marini, Sri Pernia Warakmulty

    Abstract

    This study investigates the development of primary students’ advanced mathematical thinking (AMT) skills in solving algebra problems using worksheets based on Tall’s three-worlds journey of mathematics. Employing an explanatory sequential design, this research integrated quantitative and qualitative data from 40 fifth-grade students. Instruments and data analyses were validated through expert judgment and triangulation. The findings reveal that students achieved AMT skills, including mathematical representation, creativity, abstraction, and proof. Approximately 40% of students reached the natural phase, 35% progressed to the natural-to-formal phase, and 35% attained the formal-axiomatic phase. These results occurred because Tall’s approach leverages children’s natural tendencies to play, imagine, and explore, fostering deeper reasoning. This study impacts mathematics education by demonstrating that AMT skills can be nurtured at the primary level through structured scaffolding, enhancing students’ cognitive development and problem-solving abilities in algebra. © School of Engineering, Taylor’s University.

    DOI: 10.14453/aabfj.v18i4.13

    Abstract

    This study investigates the influence of the startup ecosystem on startup business performance in Capital Cities (Jakarta, Bogor, Depok, Tangerang, and Bekasi), emphasizing the roles of iterative incremental strategies and lean startup programs. This study also examines the similarities between Central Asian countries like Kazakhstan, Uzbekistan, and the Indonesia region. Central Asian countries face unique challenges, including less mature ecosystems, regulatory hurdles, and cultural attitudes toward entrepreneurship. Using Partial Least Squares Structural Equation Modeling (PLS-SEM) on data from startups aged 1-10 years, the research reveals that these strategies significantly mediate the relationship between ecosystem support and startup success, enhancing market optimization, innovation, and sustainability. Startups achieve better financial and nonfinancial outcomes by effectively leveraging ecosystem structures through agile methodologies. By drawing on capital city experiences, Central Asian policymakers can improve startup environments through robust support structures, regulatory clarity, and education on agile methodologies. This research offers a model for enhancing startup business performance via ecosystem support and strategic agility, informing policy and program development in other regions. © 2024, University of Wollongong.

    DOI: 10.1016/j.jag.2024.104274

    Abstract

    Equitable internet coverage has emerged as a key global priority, which is essential for promoting inclusive and sustainable development. The Indonesian government aims to provide universal internet access by 2024, particularly in remote regions. This study introduces a novel machine-learning-based approach to identify the priority areas for deploying Base Transceiver Station (BTS) towers, which are crucial for achieving the internet access targets of the government. A BTS Network Priority Index was developed by integrating the internet demand estimates with a BTS suitability index derived from key predictors: proximity to fiber optic stations, physical–environmental suitability, and infrastructure–economic readiness. The model identified areas with high internet demand and high BTS suitability as the most critical for immediate development, covering 20 km2. Additionally, future BTS development should target areas with high demand but medium suitability (900 km2) and medium demand but high suitability (280 km2). To validate the methodology, the Random Forest model was employed, which achieved an area under the curve value of 0.7315, indicating strong predictive performance. For the BTS Deployment Suitability parameter, the median was 0.65, with the lower and upper quartiles at 0.44 and 0.85, respectively, confirming that most proposed locations are highly suitable for development. This systematic approach provides data-driven insights for the equitable distribution of BTS towers to ensure efficient internet infrastructure expansion across Indonesia. Furthermore, the study offers a framework that can be adapted by other countries aiming to improve their digital infrastructure and achieve comprehensive, equitable internet access. © 2024 The Author(s)

  • Social Welfare of Rural Communities as a Function of Social Workers’ Empowerment

    Social Welfare of Rural Communities as a Function of Social Workers’ Empowerment

    Authors: Dewi Kurniasih, Maisya Chaluela Anjani

    DOI: 10.29333/ejecs/2350

    Abstract

    Social workers play an important role in uplifting rural communities’ living standards. Considering the important role of social work services in dealing with the existence of potential issues of poverty and poor economic conditions in rural communities, more specifically in emerging economies, the current study integrated the community-based targeting view with empowerment theory to determine the social workers’ role in achieving community welfare in rural areas. Using rural household survey data from 597 households from 15 rural communities in two provinces of Indonesia, modern statistical tools, that is, SmartPLS analyzed the data. Results showed that social workers’ work relationships, skills and varieties, and moral alignment with rural communities enhance their empowerment qualities. The empowerment of social workers further transmits the significance of their role in helping rural communities bring economic development and welfare by providing basic needs of education, health facilities, employment opportunities, etc. The current study findings are valuable for practitioners and policymakers, specifically for focusing on rural community development programs by utilizing social workers’ efforts and extending their social networks to extract maximum benefits. © 2025, Florida Gulf Coast University.

    Authors: Harun Sujadi, Budiman B, Nunu Nurdiana, Dony Susandi, Elba Ghiffari Fitriasina, Trustorini Handayani

    Abstract

    Traditional farming in chili cultivation often needs help in monitoring plant conditions efficiently. Farmers generally use manual methods to identify pests and determine soil nutrient requirements, which are often inaccurate and time-consuming. This study aimed to improve the efficiency and productivity of chili cultivation by implementing smart farming technology using the YOLO (You Only Look Once) algorithm for real-time leaf pest detection. The method used is system development, which includes data collection, model training, and system performance evaluation. The test results showed that YOLO technology can identify pests with reasonably high accuracy, allowing farmers to take quick and precise action. The implementation of smart farming is expected to increase productivity, reduce losses due to pests, and support sustainable agricultural practices. The main contribution of this study was the development of a YOLO-based monitoring system that can support the efficiency of chili farming in Indonesia. © School of Engineering, Taylor’s University.
