The purpose of this study is to analyze the factors in community-based waste management and analyze the environmental, economic and social impacts of waste management in Marpoyan Damai District, Pekanbaru City. The approach of this research is quantitative analytic with cross sectional research design. The population in this study were all family heads in the Tangkerang Barat sub-district Marpoyan Damai Pekanbaru City as many as 4,345 households with a sample of 98 people. The results of this study are there is an influence between education (p value = 0.006), infrastructure (p value = 0.003), knowledge (p value = 0,000) with community participation in household waste management in Marpoyan Damai District, Pekanbaru City. The logistic regression analysis results found that the education variable has a value of p = 0.048 and an OR 2.888 which means that education has 2 times the risk of waste management. Infrastructure variable has a value of p = 0.001 and OR 6.838 which means that infrastructure has 6 times the risk of waste management. Knowledge variable has a value of p = 0,000 and OR 9,617 which means knowledge has 9 times the risk of waste management. The environmental impact of proper waste management is decreasing the volume of waste generation and environmental damage. Economically, there is currently no economic value to waste management, other than the public does not understand waste management that has economic value with 3R. Inadequate waste management causes low levels of public health, so people need to pay more for treatment. Socially, most people do not care about waste management and even though there is waste management it is still individual and not organized in an integrated way.

Intensive agricultural practices in the upper land of the Indragiri river bring about problem to oxbow-lakes spreading out along in the middle and downstream of the river. Danau Sungai Sorik (DSL) typically included to oxbow-lake, situated in the middle part of Indragiri River, one of four big river in Riau Province, Sumatera. Since the catchment area of the lake were totally urban, accordingly the dynamic equilibrium of lake ecosystem were shifted. The lakes were reportedly degraded in terms of hydrological regime, high sedimentation, fully vegetated and low biological diversity. The local government has repeatedly normalized the depth of the lake in related to development of water attraction, restocking of invading species of fish, cage culture and rice field along the edge of the lake. The present papers aimed at characterizing and assessment of physicochemical and biological properties of the water. Further, potential threats on the sustainability of the lake were assessed. Based on chemical properties of water including BOD5, phosphate and Nitrate range were of (3.26-7.43), (0.11-0.13) and (0.229-0.433) m/L, respectively, were categorized into un-equilibrium or slightly polluted. The water transparency appeared low (25-29) cm, the pH of 6.0-6.5) and temperature of 31-32 0C. Apparently, the diversity index (H), dominancy index and similarity index of phytoplankton ranged from (0.9110-1.2211), (0.3201-0.6136) and (0.3939-0.6290, respectively.

Environmental pollution that occurs in Tanjungpinang City, cannot be separated from the pollution of the aquatic ecosystem. Water pollution is caused by the presence of waste from residential activities, shops, industry, and other activities that produce waste. Likewise, what happens in the waters of the Sungai Jang, the activities of settlements, shops, industry can cause water pollution in this area, so a study is needed to see the extent of environmental pollution. The indicator used to determine the level of water pollution is by looking at the saprobity index through the phytoplankton community. This research was conducted by dividing the research stations based on differences in activity, namely; station 1 (settlements), station 2 (mangroves), station 3 (shops, industry), station 4 (reclamation). The results showed that the composition of the phytoplankton species found in the waters of the Sungai Jang, Tanjungpinang consisted of 17 species which were classified into 5 divisions. Diatomae types have the most number of species among other divisions, and the most dominating. The dominance of phytoplankton from the class Bacillariophyceae (Diatomae) cannot be separated from the role of nutrients in the water. The average saprobic index value of -0.39 is classified as Moderately Polluted (Meso Saprobik). Pollution that occurs is a result of organic waste from existing activities, causing an increase in nutrients. From the results of measurements in the field, the nutrient content (nitrate and phosphate) in the waters of the Sungai Jang had exceeded the quality standard.

Pelalawan District has several sleep peatland areas, which overgrown with grass weeds. This area has the potential to become a sources of beef cattle farming feed in the intensive livestock system. The potential of the beef cattle market is still prospective as a source of protein demanded by the majority peoples. This study aims to valuate and evaluate the potential carrying capacity and economic value of sleep peatlands area as forage provider. This research method was descriptive approach. The data used in this study is secondary data collected from various reliable sources and previous related research. Carrying capacity was expressed by estimate the land's ability to provide cattle feed. Economic analysis is carried out by estimate profit which obtained from the intensive beef cattle farming system. The analysis results shows that sleep peatland areas that potential to supports intensive beef cattle farming around 3,210 ha with carrying capacity = 9,078 cows/year. This carrying capacity was higher than the current beef cattle population around 1,992 cows. The potential economic value reaches IDR 45.56 B/year, which is higher than the current actual economic around IDR 9.99 B. It’s necessary to improve management aspects by integrating the development of intensive cattle farming systems with community-based peatland restoration programs, corporate social responsibility, and SDGs achievement commitments. This requires a solid partnership among stakeholders that will increase the management dimension towards a more sustainable way.
