Implementing community-based mangrove forest management (CBMFM) with a carbon credit system is a potential way to reduce the degradation. This management model is also in line to support the achievement of sustainable development goals (SDGs). The analysis results showed that the current management was yet optimal, due to the lack of sustainable management dimensional practices, including human, natural, and financial resources. The strategy to reduce the current management gap is as follows: (1) Increasing the capacity of human resources for managers and institutions; (2) Application of collaborative management; (3) Accountable budgeting; (4) Preparation of an integrated management plan; and (5) Technology management.

The aim of the present empowerment study was to utilize and process palm fronds with silage technology as cattle feed and cattle feces as biogas. The service method was the Participatory Action Research and the development of practical knowledge in understanding the social, economic, cultural, and environmental conditions of society. The results showed that palm frond silage could be used as ruminant feed due to its smooth texture and low pH. Additionally, biogas with a capacity of 6 m3 can be produced from cattle with a maximum number of 5-6 cattle. The conclusion of this public service is that by utilizing palm fronds in the ration can be used cattle feed. As well as cattle feces can be used biogas to reduce people’s living costs especially for ration feed and gas.

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

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.

The research aims at analysing uncontrolled social behaviour impact of self-management scheme on Oil Palm Plantation Sustainability in Riau Province, Indonesia. The method used in this research is a survey method. The research was carried out in Rokan Hulu, Kampar, and Siak Regency of Riau Province. A descriptive analysis was used to describe uncontrolled social behaviour. The findings also revealed that there was a correlation between uncontrolled social behaviour (economic and social behaviour) and the sustainability of the ecology of the oil palm plantations. The better the social behaviour, the better the ecological condition is. On the other hand, the worse the social behaviour, the worse the ecological condition is.

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. Di Desa Tanjung Leban merupakan salah satu desa dengan tingkat kebakaran cukup tinggi terutama pada tahun 2012, 2013, dan 2015. Banyak lahan bekas terbakar dibiarkan menjadi lahan tidur yang pada akhirnya menjadi areal yang rawan kebakaran karena kurangnya kontrol terhadap lahan tersebut. Menyikapi hal tersebut maka perlu dilakukan kegiatan restorasi ekologi lahan gambut di Desa Tanjung Leban melalui kegiatan revegetasi. Pelaksanaan kegiatan dengan motode pendampingan melalui fasilitator desa yang ditempatkan di Desa Tanjung Leban.
