Abstract

The telemedicine software lets users schedule appointments with physicians or hospitals, purchase medications online, read health-related news and publications, and have online consultations with doctors. Public opinion is necessary for this application to meet societal needs. The public's perception of contemporary health applications can be ascertained by looking to public opinion. Fine-grained sentiment analysis is used in public opinion taking to extract information from evaluations posted by the public and categorize it into positive and negative groups. Using RapidMiner as a supporting tool, sentiment analysis uses the Naïve Bayes Classification algorithm and Support Vector Machine to determine an accuracy value. After analyzing data from two different sources—Twitter and Playstore—it can be said that the Support Vector Machine algorithm performs 90.99% more accurately in predicting public opinion than the Naïve Bayes algorithm, which achieves 88.55% accuracy.

Abstract

The problem with this research is the services provided by Puskesmas Curug seem to have excessively long waiting times. In light of this problem, it is imperative to establish a forecast in order to improve the readiness of healthcare facilities in delivering patient care. The forecast for the number of patient visits at Puskesmas Curug was made using data from the years 2015-2018, including visits from both the general public and those covered by the BPJS. Three techniques, specifically linear regression, single exponential smoothing, and autoregressive integrated moving average, are utilised to predict and ascertain the most precise forecasting accuracy. Furthermore, this study has created a representation that can be used by the Curug health centre. The research findings suggest that the ARIMA technique demonstrated the highest level of accuracy, with a precision rate of 73%. The visualisation result will be transmitted to the Puskesmas and then evaluated.
