Abstract

Based on data from the Statistics Bureau of South Sulawesi Province, the open unemployment rate in Makassar City has remained consistently high over the past ten years, averaging 11.41%. This highlights a persistent labor market issue and positions Makassar as the leading contributor to the open unemployment rate in the province. To support effective policymaking and early intervention strategies, it is essential to forecast future unemployment trends based on historical data. Therefore, this study aims to forecast the open unemployment rate in Makassar City over the next five years using a machine learning approach. Among the available forecasting methods, the Backpropagation Artificial Neural Network (ANN) was selected due to its proven ability to model complex, non-linear relationships often found in socio-economic data. ANN is particularly effective in handling temporal dynamics without assuming linearity or stationarity, unlike traditional statistical models. In this study, the forecasting process involved data normalization, scenario-based data partitioning, ANN architecture design, and model training and testing. The model with the best performance consisted of 11 neurons in the input layer, 55 neurons in the hidden layer, and 1 neuron in the output layer, using 80% of the data for training and 20% for testing. This configuration yielded a forecasting accuracy of 91.896%, with a MAPE of 8.131% and an MSE of 0.003. The denormalized results forecast a steady decline in the open unemployment rate from 9.078% in 2023 to 7.248% in 2027, indicating a positive trend in employment. Nevertheless, it is important to acknowledge the limitations of forecasting models and the potential influence of external factors that may affect actual outcomes.

Abstract

This study aims to build and analyze the SELR mathematical model in the context of the Independent Curriculum, in order to explore and predict the gap in student achievement between urban and remote areas in South Sulawesi. This study combines theoretical studies and applications by conducting simulations using Maple software. The study population involved 400 students from urban areas and 400 students from remote areas where simulation data was used to predict the dynamics of adaptation to the Independent Curriculum. The results showed that the Independent Curriculum was not fully effective in addressing the achievement gap, with a low basic reproduction number (R₀), both in urban and remote areas. The R₀ value of 0.204 in urban areas and 0.614 in remote areas indicates that the spread of curriculum adaptation is still limited and cannot create a significant impact on improving student achievement. This study indicates the need for additional adjustments and interventions in the implementation of the Independent Curriculum to achieve more equitable and inclusive results in various regions .

Abstract

Pengenalan gestur hitungan jari (1–5) atau daktilonomi memiliki peran fundamental dalam pembelajaran matematika dasar sebagai representasi kognitif yang terwujud (embodied numerosity). Namun, model klasifikasi pada Natural Hand Digit Dataset masih menunjukkan akurasi terbatas (sekitar 66%) akibat gangguan latar belakang, variasi posisi, dan pencahayaan. Penelitian ini bertujuan untuk meningkatkan performa pengenalan gestur angka melalui lokalisasi tangan berbasis YOLOv10x yang dilatih pada dataset HaGRID sebagai tahap pra-pemrosesan, serta mengintegrasikan Grad-CAM untuk explainable artificial intelligence (XAI). Metode yang digunakan terdiri atas deteksi dan pemotongan wilayah tangan menggunakan YOLOv10x, kemudian klasifikasi jumlah jari menggunakan transfer learning ResNet50 dengan fine-tuning dan callback. Hasil eksperimen menunjukkan bahwa penggunaan citra hasil lokalisasi tangan (cropped) meningkatkan akurasi hingga 73,98% dengan macro F1-score 72,44%, jauh lebih baik dibandingkan citra asli (akurasi 41,66%). Visualisasi Grad-CAM mengonfirmasi bahwa model benar-benar fokus pada konfigurasi jari yang relevan pada prediksi benar, sementara pada prediksi salah, peta aktivasi mengungkap penyebab kesalahan (misalnya angka "2" dikenali sebagai "1" karena fokus pada satu jari). Penelitian ini menyimpulkan bahwa pendekatan lokalisasi tangan sebelum klasifikasi efektif meningkatkan performa dan ketahanan sistem, sementara Grad-CAM memberikan transparansi dan interpretabilitas yang penting untuk membangun kepercayaan dalam aplikasi pembelajaran matematika interaktif.
