Abstract

Excessive body fat accumulation characterizes obesity, a medical condition primarily caused by an energy imbalance. This excess fat is stored throughout the body, including the abdomen, thighs, and arms. Obesity is a global health concern, prevalent in Indonesia, impacting physical, psychological and social well-being. Women are more susceptible to obesity due to a combination of biological and lifestyle factors. A community health center study of 156 patients revealed that 71.20% exhibited central obesity, with women comprising 76.60% of this group and men 31.6%. This study focuses on the disproportionate impact of obesity on women. To better understand and address obesity, classification is crucial. This study uses a Decision Tree method to classify 898 women based on 14 assessments for high obesity risk, comparing its performance using three attribute selection criteria. The Decision Tree (Gini Index) model achieved 77.22% overall accuracy (Figure 12). The Normal category has 83% precision and 88.30% recall. The Overweight category had 62.50% precision and 63.83% recall. The Obese category had 75% precision and 66.67% recall. The Underweight category achieved 100% precision and recall. While the model demonstrates good classification performance, particularly for Normal and Underweight categories, it requires further refinement to better differentiate between Overweight and Obese individuals.

Abstract

Human development and economic welfare are the two main pillars in the progress of a region. This study aims to analyze trends in education indicators, including Expected Length of School (HLS) and Average School Length (RLS), as well as their relationship with Per Capita Expenditure in East Kalimantan Province for the period 2020-2025. This topic was raised because there is a consistent gap between expectations and realization of education that can affect economic productivity. The novelty of this study lies in the use of recent time-series data covering the post-2020 recovery period, providing strong  evidence for policymakers. This research method uses a quantitative descriptive approach and simple linear regression analysis with data sources from the Central Statistics Agency (BPS) of East Kalimantan. The results of the study showed a significant positive trend, where RLS grew by 3.38% and Per Capita Expenditure grew by 21.54% during the observation period. The main findings show a very strong correlation (r=0.989) between education and the economy, where the regression model estimates that every 1-year increase in average school length is associated with an increase in per capita expenditure of Rp7.94 million. In conclusion, the acceleration of education realization has direct implications for increasing people's purchasing power. Therefore, the strategy of accelerating compulsory learning is crucial to boost the regional economy. Keywords: Education Indicators; Development Economics; Human Capital;      Expenditure per Capita; East Kalimantan

Abstract

This study examines the impact of Expected Years of Schooling (EYS) and Adjusted Expenditure per Capita (AEPC) on Life Expectancy (LE) in 10 regencies and cities in East Kalimantan Province during 2022–2024 (BPS East Kalimantan Province, 2024). This topic is relevant because East Kalimantan exhibits strong economic performance yet continues to face disparities in human development across regions. At the same time, empirical studies that directly link education and household purchasing power to life expectancy at the district and municipal level in this province remain limited (Susanti Hidayat, 2020; Williyan Hasmarini, 2024). The novelty of this study lies in the use of recent panel data for 10 regencies and cities that simultaneously incorporate AEPC and EYS as determinants of LE, thereby providing more context-specific empirical evidence for East Kalimantan (Hasanah et al., 2021; Swastika Arifin, 2023). The study employs secondary data sourced from BPS East Kalimantan Province, comprising EYS, AEPC, and LE for 2022–2024, which are analysed using panel data regression, specifically the Common Effect Model (CEM). The model's validity is assessed using statistical tests, namely the t-test, the F-test, and the coefficient of determination (Statistics Indonesia, 2024; BPS East Kalimantan Province, 2024). The estimation results indicate a positive and statistically significant relationship between EYS and AEPC, and an increase in LE, while these two variables jointly explain approximately 71–73% of the variation in LE across regencies and cities (Hasanah et al., 2021; Meilinna et al., 2024). These findings suggest that expanding access to and improving the quality of education, alongside strengthening household economic capacity, are crucial prerequisites for improving health status and overall quality of life in East Kalimantan (Sari Syechalad, 2022; Swastika Arifin, 2023). Keywords: Life Expectancy (LE), Expected Years of Schooling (EYS), Adjusted                   Expenditure per Capita (AEPC), Panel data, Multiple linear regression.

Abstract

Indonesian Sign Language (BISINDO) serves as a communication medium for deaf individuals to engage with their environment. Alphabet gestures in BISINDO play a crucial role in the formation of words and sentences. Nonetheless, the automatic recognition of BISINDO alphabet movements remains a difficulty in the advancement of accessible technology. This research intends to categorize BISINDO alphabet gestures via the Convolutional Neural Network (CNN) model. The CNN approach was used due to its proficiency in recognizing visual patterns and images. The dataset comprises BISINDO alphabet gesture photos captured from diverse perspectives and lighting conditions. The data processing procedure encompasses pre-processing phases, including picture normalization, data augmentation, and the segmentation of the dataset into training, validation, and test subsets. The constructed CNN model has multiple convolutional and pooling layers to thoroughly extract visual characteristics. The study's results indicate that the CNN model can classify BISINDO alphabet gestures with a high accuracy of 90% on the test data. This model's deployment is anticipated to aid in the creation of automatic sign language translation programs, hence enhancing communication between the deaf community and the general populace. This study demonstrates the potential of CNN models to support the development of inclusive communication technologies for the hearing impaired in Indonesia, particularly for under-researched sign languages like BISINDO.
