Abstract

The government realizes the importance of the problem of poverty by making various efforts, one of which is holding social assistance programs for the poor. One of the government policies is the Family Hope Program (PKH). The situation in the community indicates that those who receive PKH assistance from the government usually use the assistance to meet the health needs of their families, schools and daily needs, which are generally consumptive. The process of processing PKH beneficiary data in the Timbang Deli sub-district is still done manually, therefore this study aims to carry out data processing with the Naïve Bayes classification by creating a system to make it easier for officers in the Timbang Deli sub-district to determine PKH beneficiaries. The method used in this study is the Naive Bayes classification method. The variables used in this study were the head of the family, number of dependents, occupation, income, number of cars, number of motorcycles, status of residence, and condition of the house. The data in this study were 100 data from PKH beneficiaries and non-recipients of Timbang Deli Village, 80 as training data, and 20 as testing data. Based on the results of a study of 20 test data for recipients and non-recipients of PKH assistance in Timbang Deli Village, Medan Amplas District, the accuracy of the truth is 80% where there are 16 data that have values according to the test data, and 4 data that have values that do not match the test data.

Abstract

The country's income is heavily dependent on taxes, which contribute to improved public well-being. Public confidence in tax authorities plays a key role in increasing tax receipts. Therefore, it is important to measure this level of confidence. One of the methods used is sentimental analysis, which helps to understand public views on regulations, services, performance, and tax policies. One of the purposes of this study is to measure the sentiment of Twitter users towards taxation in Indonesia. Sentiment analysis involves data collection processes, initial data processing, separation of datasets, feature extraction, classification, and evaluation. The classification model used is Multinomial Naive Bayes with a comparison of 80% training data and 20% test data. The results show that 89.65% of tweets about taxation in Indonesia have negative sentiment. The model evaluation was carried out on two test scenarios, namely initial data and randomly under-sampleed data. Classification on initial data achieved accuracy of 89.97%, precision of 46.68%, and sensitivity of 33.61%. Whereas on undersampling data results, accuration reached 53.28%, accurateness of 52.66%, and sensibility of 52.52%. Analysis showed significant differences between the two scenarios in which undersammpling techniques resulted in a more balanced distribution of data. Despite this, the model still faces difficulties in classifying positive and neutral data due to the dominance of negative sentiment.

Abstract

Music has been an inseparable part of human life since ancient times. One form of music that is often studied is monophonic music, which consists of a single note played at a time. In the digital era, melody transcription has become an important aspect of music processing, allowing sound to be converted into musical notation. This study focuses on melody transcription from monophonic sound recordings using the Fast Fourier Transform (FFT) method. The research aims to analyze the accuracy of FFT in extracting frequency components from monophonic signals and converting them into musical notation. The research methodology involves collecting monophonic sound recordings from piano and guitar, preprocessing the audio to remove noise and normalize volume, applying FFT to extract frequency features, and mapping these frequencies into musical notation. The evaluation process is conducted using Dynamic Time Warping (DTW) and a confusion matrix to measure accuracy, precision, recall, and F1-score. The results show that the FFT-based transcription system achieves an accuracy rate of 99.24% for piano and 98.86% for guitar. The study also highlights the impact of noise and audio quality on transcription accuracy, as well as the limitations of FFT in detecting closely spaced frequencies. Despite these limitations, FFT proves to be an efficient method for melody transcription in simple monophonic music. Future research could explore hybrid approaches combining FFT with other pitch detection algorithms to improve transcription accuracy.
