The palm oil industry has a strategic role in economic development in Indonesia, especially in alleviating poverty and creating other businesses that can support the industry. Operational activities in the palm oil industry are closely related to environmental issues (deforestation, land-use change, and air pollution) and social conflict. The certification program is an effort for the palm oil industry to implement sustainable development. The certified palm oil industry will increase industrial profitability in the long run to increase investor interest in the future. The decision to choose palm oil industry stocks that carry out sustainable practices and generate maximum returns is an exciting issue, but how investors can choose the right stocks and the minimum risk level. This study aims to apply the decision-making model to choose the optimal stock in the palm oil industry, which involves sustainable certification and risk criteria. The method used in this study was the Preference Ranking Organization Method for Enrichment Evaluation (PROMETHEE) based on the Indonesia Stock Exchange (IDX) data. Determinants of stock selection decisions from previous research are considered criteria for decision making. Through the PROMETHEE method, a list of the rankings of the oil palm industry shares can be generated. The sustainable certification and risk criteria can be used as a reference for relevant stakeholders such as investors. Further studies need to be developed by adding non-financial criteria in the firm and developing the criteria to differentiate each other.

Information and Communication Technology (ICT) is currently developing rapidly along with its increasingly important role for both individuals and organizations. One form of ICT development is E-Commerce which serves as a comprehensive virtual marketplace. Based on macroeconomics context, the role of E-Commerce needs to be explored further, especially the relationship between Business to Consumer (B2C) E-Commerce and Gross Domestic Product (GDP), a topic that remains underexplored. The purpose of this study is to observe the nexus between B2C E-Commerce and GDP using two main classifications, namely: 1) economic status and 2) geographical continent. A panel-data regression analysis was conducted involving 117 countries from 2016 to 2020. The results showed that B2C E-Commerce had a positive and significant effect on GDP. In addition, the increase in e-commerce has been found to have the potential for nation growth in both developing and emerging economies. Notably, Africa and Asia-Oceania continents presented considerable opportunities to harness E-Commerce as a driver of national economic development. These findings provide important managerial and policy implications for governments and stakeholders in defining strategies to promote inclusive digital economic growth.

The Internet is widely recognized as an important technology to accelerate export performance. In the case of energy trade, the issue of export efficiency must be achieved for every exporter country, including Indonesia. The essential input factor to achieve maximum efficiency of trade is to utilize the internet as a technological factor. Therefore, the objective of this study is to examine the impact of the internet on the efficiency of primary energy exports in Indonesia. The study employed the Stochastic Frontier Gravity Model (SFGM) to analyze data from 26 destination countries spanning the period from 2011 to 2020. The result reveals that the condition of internet technology from importers, proxied by fixed broadband subscriptions and secure internet servers has a significant effect on Indonesian export energy performance. Furthermore, the addition of internet technology enhances the Indonesian primary energy export efficiency by comparing the efficiency before and after involvement of the internet. Therefore, the condition of internet technology from importer countries must be considered to maintain the export performance of Indonesia's primary energy to the global market.

One of the leading industries that affect economic growth in Indonesia is the palm oil industry. The role of this industry depends on the level of exports from European Union countries. Based on the COVID-19 pandemic situation, international trade activities are hampered and could affect industry performance from a stock perspective. Therefore, this study aims to explore the impact of the COVID-19 cases that occurred in the European Union and related macroeconomic variables on the stock performance of the oil palm industry in Indonesia. This research also examines the impact of COVID-19 on certified sustainable companies and companies that are not certified. Panel regression was applied in this study with Eviews 11 Software.This research's observations are 13 palm oil companies in Indonesia which are listed on the Indonesia Stock Exchange (IDX) from March 2, 2020, to August 31, 2020. This study's results reveal that the world CPO prices and market capitalization affect the activities shares of palm oil companies in Indonesia.Meanwhile, from the grouping of certifications within companies, the impact of COVID-19 in the European Union was more substantial on companies that were certified as sustainable. Based on these results, The COVID-19 case in the European Union must be a concern for palm oil companies in Indonesia.
