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 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 planation 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 rural economy and land sustainability. The proposed development strategy for superior commodities in plantation is in line with the sustainable development goals (SDGs) in Riau Province, Indonesia.

This research aimed to develop high order thinking skills  workheet in momentum, impulse, and collision topic for senior high school This type of research is Research and Development  follow 4D models, includes : define, design, develop and disseminate. Data collection instruments used validation sheets for given to 5 validator, Aspects assessed include graphic, presentation, language, and the contents of workheet. Based on the result of data analysis showed that all aspects got average score in the range of 3.4 to 4 with categories of  very high. Thus, high order thinking skills was valid. For the purposes of testing the worksheet is given on 68 students. to measure the effectiveness of worksheet used  Higher Level Thinking Ability Test that amounts to 12 items. Based on the result of data analysis indicate, There is difference of higher order thinking skill of students who use HOTS worksheet than who are not use HOTS worksheet, where the average Higher Order Thinking Skill on students who use HOTS worksheet higher

Purpose The purpose of this study is to analyze strategies for controlling potential environmental impacts as a result of developing oil palm plantations. Design/methodology/approach Research sites in the first year have been carried out in potential areas for the development of oil palm plantations, both through plasma through Badan Usaha Milik Negara (state-owned enterprises) and Badan Usaha Milik Swasta (private-owned companies) and self-help by the community. The research locations were carried out in the Riau mainland areas, including Kampar, Rokan Hulu and Kuantan Singingi regencies. In contrast, the Riau coastal areas were Pelalawan, Siak, Bengkalis, Indragiri Hilir, Indragiri Hulu and Rokan Hilir. The two research areas have different productivity caused by differences in soil fertility. The method used for data collection is the rapid rural appraisal method, which is a participatory approach to obtain data/information and general evaluation in the field in a relatively short time. Findings Oil palm commodities are the most popular, especially in the Riau region. This is evidenced by the rapid development of oil palm plantations, namely, 1,119,798 ha in 2001 and increased to 2,372,402 ha in 2013. During the 2001–2013 period, the average growth rate was 6.46% per year, whereas other plantation commodities such as rubber and coconut have decreased. #R2.6 An increase follows the expansion of the plantation area in the production of fresh fruit bunches (FFB). Crude palm oil (CPO) production from 1,792,481 tons in 2001 increased to 7,570,854 tons in 2013, with an average annual growth of 12.76%. CPO production capability in Riau is supported by 172 palm oil mill (POM) units with a processing capacity of 7,800 tons per hour. POM is not spread evenly but is concentrated in nucleus and plasma plantations. Independent smallholders with their scattered land located far from the existing POM. This condition causes the low quality of FFB to the mill due to the distance between the plantation and POM. Originality/value The virtue of this research is to find an institutional arrangement strategy for oil palm agriculture to spur growth through the development of the downstream palm oil industry. The strategy is intended to create economic added value so that efforts to accelerate community economic development can be increased.

The existence of peatlands plays a very important role both locally, regionally, and globally. Besides having an ecological function to maintain biodiversity and environmental balance, it also has its economic and socio-cultural functions. Furthermore, it has provided enormous benefits for life and has had positive social and economic impacts. Peat ecosystems have been damaged due to the mismanagement of land. Areas that play specific roles in its sustainability have been converted to lands for business activities, which contradicts their characteristic function. Land cover restoration policies will be useful for improving the quality of participatory-based land cover, protecting peat domes, and conserving watersheds (DAS). An increase in greenhouse gas (GHG) emissions, which occurs due to insufficient peatland management is a serious threat to local communities and their livelihoods. Furthermore, the ecosystem can be conserved by ensuring that water is properly managed, drainage to cultivated areas is limited and peat swamp forest systems are protected. The application of eco-hydro technology can be beneficial to biodiversity as it minimizes degradation, reduces carbon emissions, and prevents fires.
