Mutual fund is one of the investment instruments widely used as an investment option. There are two essential things to be considered by the Investment Manager as a mutual fund manager: the stock selection and the market timing ability. The Covid-19 pandemic has caused many investors to experience potential investment losses. Understanding stock selection and market timing will be needed for determining which Investment Managers perform well in managing equity mutual fund, especially while dealing with the Covid-19 pandemic. The objective of this study is to analyze the ability of Investment Managers to perform stock selection and market timing, the performance of equity mutual fund, and the effect of stock selection and market timing ability on the performance of equity mutual fund in Indonesia. This study applies the Fama net selectivity methods to assess stock selection ability and Treynor-Mazuy and Henriksson-Merton models to analyze market timing ability. Sharpe, Treynor, and Jensen's alpha methods are also used for measuring mutual fund performance. The data is processed per mutual fund to recognize each mutual fund's stock selection and market timing ability. Furthermore, the research spans two time periods: before and following the Covid-19 pandemic. A dataset of 104 equity mutual funds from 2016-2021 has been analyzed. The findings show that only 9 and 12 Investment Managers have stock selection ability prior to and following the Covid-19 pandemic, respectively. According to Treynor Mazuy model, there are only two Investment Managers with market timing ability prior to the Covid-19 pandemic, and only twelve Investment Managers have market timing ability during the Covid-19 pandemic, according to the Henriksson-Merton model. Every mutual fund with stock selection ability outperformed the benchmark. However, not all equity mutual fund with market timing ability outperformed the benchmark.

An increase in population with various activities and lifestyles of a community has an impact on increasing volume, type, and characteristics of waste. The increase in the amount of waste needs to be balanced with the government and the ability to manage waste, so it is necessary to involve the community. This study aims to measure community participation in managing household waste that will support the agricultural sector. This study was carried out in Takalar Regency because Takalar is one of Indonesia’s regencies that has been successfully awarded the Community-Based Total Sanitation (STBM) from the Indonesian Ministry of Health and the Sustainable STBM Award in waste management. The method used in this study was a descriptive analysis of questionnaire data which was filled by 1011 villages of Takalar Regency. The study found that most of the Takalar citizens have participated in the waste management program initiated by the government of Takalar Regency. However, only a small number of residents process waste into products that support the agricultural sector. This research provides implications for evaluating program effectiveness and finding opportunities for further improvement in regulations.
