    No full text
    Poverty is a multidimensional problem that requires prompt and appropriate handling to maintain a dignified human life. In Manyaran Sub-district, Semarang City, the distribution of social assistance often faces obstacles due to limited human resources and a manual selection process for recipients. Therefore, a Decision Support System (DSS) is needed to assist the selection process in a more objective and efficient manner. This study aims to develop a DSS for determining social assistance recipients in Manyaran Sub-district by combining the Analytic Hierarchy Process (AHP) and Multi-Objective Optimization on the basis of Ratio Analysis (MOORA) methods. AHP is utilized to determine the weight of each criterion, while MOORA is used to calculate the final score of each recipient candidate. The results show that among the ten analyzed candidates, the individual coded P09 achieved the highest final score of 0.575. The top five candidates with the highest scores were declared eligible to receive social assistance, while the others were declared ineligible. The application of the AHP and MOORA methods in this DSS effectively improves the accuracy, objectivity, and efficiency of the selection process for social assistance recipients in Manyaran Sub-district.  Poverty is a multidimensional problem that requires prompt and appropriate handling to maintain a dignified human life.

    Full text link
    Early detection of arrhythmia through electrocardiogram (ECG) signals is crucial for preventing severe cardiac conditions. This study proposes a binary classification approach using statistical features derived from wavelet-transformed ECG signals. The MIT-BIH Arrhythmia Database was used, with signals filtered using a 0.5–50 Hz Butterworth bandpass filter. Signals were segmented into 360-sample windows with 100-sample overlap and labeled based on the majority annotation within each window. Wavelet transformation using Symlet 8 at level 4 was applied, followed by the extraction of eight statistical features: mean, standard deviation, variance, skewness, kurtosis, interquartile range (IQR), root mean square (RMS), and zero crossing rate (ZCR). These features were classified using MLP, KNN, and SVM models. MLP and KNN achieved the highest accuracy of 92.46%, while SVM had lower accuracy (72.99%) but high recall (94.21%). The results demonstrate the effectiveness of wavelet-based statistical features for lightweight and accurate arrhythmia detection.Early detection of arrhythmia through electrocardiogram (ECG) signals is crucial for preventing severe cardiac conditions.

    Financial management that is less careful and less able to choose each expense will have an impact on the imbalance of income and clinic expenses, if it happens continuously will cause the clinic to gradually be unable to operate anymore. Each type of clinic expense certainly has a different level of importance, the level of importance is influenced by various variables such as the nominal expenditure, deadline date, user of the expenditure, level of importance, purpose of use. The problem that occurs is that the fulfillment of the needs of the clinic is often unable to prioritize expenses or without considering the level of importance of expenses. There needs to be an appropriate priority scale to regulate the level of expenditure that will impact the financial security of the clinic so that it can support the smooth operation of the clinic, with the aim that the clinic will be able to grow or develop for the smooth provision of health services to the community. One method that can be implemented to help prioritize the use of the clinic budget is simple additive weighing. From the results of the comparison between the ranking of the old model and the ranking using the simple additive weighing method, there are two different sequences, namely codes A7 and A14, resulting in a 90% accuracy rate.Improper financial management and the inability to properly manage each expense will lead to an imbalance in the clinic\u27s income and expenses. If this continues, the clinic will eventually become unable to operate. Each type of clinic expense naturally has a different level of importance, influenced by various variables such as the nominal amount of the expense, the time limit for the expense, the user of the expense, the level of importance, and the intended use. The problem that occurs is that meeting the clinic\u27s needs often fails to prioritize expenses and does not consider the level of importance of the expenditure. An appropriate priority scale is needed to regulate the level of expenditure that will impact the clinic\u27s financial resilience so that it can facilitate the smooth operation of the clinic, with the aim of the clinic being able to grow or develop for the smooth provision of health services to the community. One method that can be applied to help prioritize the use of the clinic\u27s budget is simple additive weighting. From the results of trials on several datasets, an accuracy rate of 90% was produced.

    One of the most prevalent malignancies in women and a major global cause of death is breast cancer. To determine whether a cancer is benign or malignant, early detection is essential. The usefulness of the Support Vector Machine (SVM) and Adaptive Boosting (Adaboost) algorithms for breast cancer classification using mammography data is compared in this study. 569 records make up the dataset, which was sourced from the Kaggle Repository and is split into 75% training data and 25% testing data. Preprocessing steps include feature and target variable creation, categorical-to-numerical conversion, data splitting, and normalization. SVM achieved an accuracy of 97%, with a precision of 98%, recall of 94%, and F1 score of 96%. Adaboost, on the other hand, achieved an accuracy of 96%, precision of 98%, recall of 92%, and F1 score of 95%. The results reveal that both algorithms are highly effective for breast cancer detection, with SVM marginally exceeding Adaboost in total performance. These findings emphasize the promise of machine learning techniques in facilitating early cancer diagnosis, hence boosting survival rates. It is advised that future research employ a wider range of datasets and investigate different classification techniques in order to improve accuracy and dependability even more.One of the most prevalent malignancies in women and a major global cause of death is breast cancer.
