The market value of a public company reflects the expectations of investors. It is influenced by many factors, both internal and external to the company. This study aims to analyze whether intellectual capital moderates the effect of the debt-to-equity ratio and earnings per share on the market value of equity. A set of historical data was collected and analyzed based on a sample of 114 manufacturing companies listed on the Indonesia Stock Exchange from 2017 to 2019. This study uses moderated regression analysis to test proposed hypotheses and a robustness test to examine the sensitivity and consistency of the study results. The findings show that the debt to equity ratio affects the market value of equity, whilst earnings per share does not affect the market value of equity. The analysis also shows that intellectual capital could strengthen the effect of the debt to equity ratio on the market value of equity. In contrast, intellectual capital could not strengthen the effect of earnings per share on the market value of equity

Fitri Hariyanti, Bekti Indasari, Almasdi Syahza, Zulkarnain, Nofrizal

Countries in the world including Indonesia agreed to continue development by carrying out the concept of Sustainable Development Goals. Many environmental problems that occur in Indonesia and the world are the result of activities carried out by companies and by households. These cause a development system that is needed not only to pay attention to economic and social aspects but also to environmental aspects. To know about the success of development in the environmental field, a disparity analysis is needed to be done by measuring the gap in environmental conditions between provinces in Indonesia using the Environmental Disparity Index. The impact of uneven development between Western Indonesia and Eastern Indonesia also affected the environmental conditions in the two regions. The environment of Eastern Indonesia was still better than Western Indonesia.

Restorasi ekologi lahan gambut bermuara pada kerusakan ekosistem lahan gambut yang disebabkan oleh aktivitas manusia baik disengaja maupun tidak. Akibat dari kerusakan tersebut menimbulkan berbagai macam masalah seperti kebakaran lahan.

Almasdi Syahza, Djaimi Bakce, Mitri Irianti, Brilliant Asmit, Besri Nasrul

Riau is an Indonesian province known for its large plantations. The plantation business makes the most significant contribution to the fiscal revenues of the province. This paper aims to innovate the rural economy through the sustainable development of superior commodities in the plantation sub-sector of agriculture. Specifically, multi-criteria analysis (MCA) was performed to determine the superior commodities in each locality. The results show that the superior commodities include palm oil, rubber, coconut, cocoa, coffee, and sago. The development of these commodities could boost farmers’ income with the added value of plantation products. On this basis, the fair use of land for all categories was highlighted from social, economic, and environmental perspectives, and recognized as essential to the development of sustainable plantations, which are integral to the rural economy and land sustainability. The proposed development strategy for superior commodities in plantations is in line with the sustainable development goals (SDGs) in Riau Province, Indonesia.
