Abstract

This article aims to find out how the parenting style taught by parents is related to students' behavior when entering education, namely elementary school, especially grade 1, where tantrums often occur in the school environment. In this case, children not only need genuine assistance from school teachings, but also from their parents' parenting style. This reflection of parents in educating is what children express when they enter their social environment, namely the school environment. Cases of children who have problems or tantrums in the school environment are closely related to what parents teach their children. The research method we use in this writing is qualitative with case study techniques, namely several data collection methods including interviews and observation. The results of this research are that teachers as facilitators cannot 100% supervise and calm children when they have tantrums in the school environment. This is caused by parents often pampering them, being supervised during learning activities, and not giving children the opportunity to interact with their environment and friends, which makes children not socialize.

Abstract

The purpose of this study is to determine the proportion of each stock that makes up the optimal portfolio so that it is easier for investors to determine which company has the optimal portfolio. The population that is the focus of this study refers to stocks belonging to the LQ45 index in the banking sector during the 2021-2023 period, namely 7 stocks. The sampling method is carried out by applying a purpose sampling technique, which results in 5 stocks that qualify according to the criteria of this study. The data used is secondary data derived from monthly stock prices. From the research results, all stocks showed positive returns, with BBRI having the highest return. In addition, the analysis results show that using the single index model approach, the stocks of the LQ45 Index members in the banking sector in the period August 2021 to July 2023 show that 4 out of 5 stocks (BBRI, BMRI, BBCA, and BBNI) form an optimal portfolio. Meanwhile, BBTN shares cannot be said to be an optimal portfolio because ERBi is smaller than Ci.
