Today, the research on the closed-loop supply chain network design with sustainability and resiliency criteria is a very active research topic. This paper provides a new closed-loop supply chain under uncertainty with the use of resiliency, sustainability, and reliability dimensions among the first studies. To model this problem, a two-stage stochastic programming approach is used. To create robust solutions against uncertainty, a conditional value at risk criterion is contributed. The proposed model aims to minimize the total cost, environmental pollution, and energy consumption while maximizing the job opportunities as the social factor. In addition to the sustainability goals, the energy consumption is considered to be the last objective to be minimized. To show the applicability of the proposed model, an automobile assembler industry is applied. To solve the model, the Lp-metric method is employed to transform this multi-objective model into a single objective one. Since this closed-loop supply chain model is complex and NP-hard, a Lagrangian relaxation method with fix-and-optimize heuristic is employed to find the upper and lower bounds for the model via different random test problems. With an extensive analysis, the proposed model shows an improvement to the total cost, CO 2 emissions, job opportunities and energy consumption.

During COVID-19, consumers of skincare products pay more attention to safety and comfort. In such a crisis, consumers seek skincare products with brand effectiveness, high quality, and persuasive reviews by social media influencers. This study investigates the influence of brand effectiveness, product quality, and celebrity endorsers on purchase intention of halal skincare products in the pandemic. The study employed a survey of halal skincare users in East Java, Indonesia. A purposive sampling of 180 female respondents was analyzed; they were followers of Safi-Skincare Instagram and aged 18 and over. Descriptive statistics indicated that religious background strengthened the factors influencing the purchase intention towards a skincare product. The data were then analyzed using multiple linear regression with a statistical level of confidence of 95%. The result showed that brand effectiveness, product quality, and celebrity endorsers significantly affect purchase intention in Indonesia during the pandemic. The study concludes that Muslim standards reinforce rigid standards applied to skincare products with a halal logo, supporting good quality performance and encouraging stronger purchase intention. This study contributes to understanding consumer behavior in the pandemic using a purchase intention framework that can be applied to the safety and comfort of other consumer products.

This paper aims to analyze the effect of earnings volatilty, net income and comprehensive income on stock prices on banking companies on the Indonesia Stock Exchange in the period of 2011 to 2016. This paper uses a quantitative approach by using secondary data consisting of 174 data of commercial banks on the Indonesia Stock Exchange, from 2011 to 2016 obtained from the Indonesia Stock Exchange website www.idx.co.id. and www.yahoofinance.com, The analysis technique used in this study is multiple linear regression. hese results indicate that net income has a positive and significant effect on the level 5% statistic of stock prices, and could be used by investors in conducting fundamental analysis to have relevant information. While earnings volatility and comprehensive income do not have an influence on stock prices, meaning that even though high earnings volatility and comprehensive income tend to have no value relevance to stock prices. Previous research has done a lot to tests of earning volatility, net income on stock prices, the results conclude that earnings volatility, net income affect stock prices. So the novelty in this study is to include a comprehensive income variable, because the Statement of Financial Accounting Standards No. 1 changes the terminology of the income statement into a statement of comprehensive income.

This study aims to estimate and predict the effect of stock prices on profit volatility, net profit, and comprehensive income on the Indonesia Stock Exchange for the period 2014-2019. The study uses quantitative analysis with secondary data consisting of 98 banking companies on the Indonesia stock exchange from 2014 to 2019. The results prove that the share price has a significant effect on net income and comprehensive income but does not have a significant effect on profit volatility, so that net and comprehensive income has relevance to the share price and investors can make both variables in conducting further fundamental research. Previous studies measured the level of volatility of earnings, net income, and comprehensive income on the share price, but when trialing other approaches by causality, share prices affect net income and comprehensive income but not for profit volatility. In this study, however, the change includes detailed income variables due to Financial Accounting Standard No. 1, a shift in terms from profit and loss statements to systematic profit and loss statements.
