Abstract

Pandemic of Covid-19 that entered Indonesia in early March 2021 limited activities in various sectors. This condition causes the economy in Indonesia to become unstable and even experience a recession in 2020. Vaccines produced by pharmaceutical companies are one of the government's ways to improve not only health but also economic conditions in Indonesia. Various reports on the Covid-19 vaccine have caused investor reactions in the capital market, one of which is in the pharmaceutical sector itself as a producer of the Covid-19 vaccine. Using the Lexicon-based method and Pearson correlation, this study aims to analyze the sentiment of the Covid-19 vaccine coverage and analyze the relationship between these sentiments and the stock price of pharmaceutical issuers. Covid-19 vaccine news data is collected from Twitter for 22 days with 500 tweets per day. The tweets were categorized into positive, negative, or neutral sentiments using the Lexicon-based method. The results of this study indicate that the media provides more positive sentiment towards the Covid-19 vaccine. A unidirectional relationship exists between the sentiment in the Covid-19 vaccine coverage and one of the stock prices of a pharmaceutical issuer.

Abstract

Indonesia failed to reach the target to reduce the percentage of unmet need KB in 2015. Province of Bengkulu which has almost 20% of family planning services from government, has a high unmet need percentage. The purpose of this research is to determine the factors that affect status of unmet need KB of women aged 15-49 years in Bengkulu 2015. Data in this study obtained from Susenas 2015. The result showed that 21,34% of women aged 15-49 years in Bengkulu in 2015 was unmet need KB and 78,65% was not unmet need KB. Using binary logistic regression, the result showed that the age of women, number of surviving children, education of women aged 15-49 years, and type of residence have a significant effect on status of unmet need KB. Socialization of family planning program on Bengkulu is needed to reduce the percentage of unmet need KB of women aged 15-49 years on Bengkulu. Further research is suggested to use other independent variables and see spatial correlation in Province of Bengkulu.
