Problem of Palm oil mill industry is POME final discharge failed to comply discharge standard and brownish black color in POME final discharge inhibits the growth of aquatic biota. In this research, we propose a treatment for POME final discharge using adsorption, coagulation and combination of coagulation and adsorption to reduce chemical oxygen demand (COD), suspended solid (SS) and color, th…
Palm Oil Mill Effluent (POME) has organic matter content and high pollutant load, therefore it requires many ponds and long times to treatment. The microalgae consortia is able to utilize organic material as a source of nutrition for its growth, therefore may reduce pollutant, time, and amount of the pond in POME treatment. This research used a microalgae consortia from POME. The aim of this re…
Energy use mostly comes from non-renewable energy sources that gradually decreased. Biofuel production from microalgae consortium can be one of the alternative energies in producing renewable energy. Lipid content in the biomass of a microalgae consortium can be converted into biofuel raw materials. The organic material contained in Palm Oil Mill Effluent (POME) can be a nutrient source fo…
Pekanbaru City as the capital of Riau Province has a high development activity along with increasing population density due to urbanization so that it results in reducing vegetation land. This condition causes an increase in surface temperature in Pekanbaru City especially in the downtown area and triggers the Urban Heat Island (UHI) phenomenon. This study aims to determine the distribution…
Agriculture widely consists of several sectors including agriculture, plantation and livestock. Agriculture as one of the contributors to greenhouse gas emissions (GHG). Greenhouse gases are produced from agriculture included CH4 of the rice field, CO2 of the use of fertilizer, CH4 of the manure management and the result of the enteric fermentation of the animal digestion process as well as N2O…
POME processing in Indonesia is generally still carried out conventionally using an open pond system. To reduce the burden of processing ponds and reduce the retention time for POME processing, further processing alternatives can be done using microalgae that can utilize the organic material contained in POME as a source of nutrients for microalgae growth. The success in using microalgae to tre…
The stabilization pond system are used in almost all of palm oil mills in Indonesia. The potential of microalgae have not utilized yet optimally in stabilization pond. Microalgae have the ability to treat wastewater. Microalgae growth can be enhanced by HRAR. HRAR is a technology that is able to increase microalgae biomass, and with a consortium of microalgae-bacteria, the elimination of organi…
Palm oil mill effluent contains pollutants and has high content of organic matter. The treatment process of palm oil mill effluent generally with open pond system that requires extensive land and a long contact time. To reduce the number of ponds needed in the process of palm oil mill effluent, microalgae Chlorella sp. by using palm mill effluent which contains organic material as a source of n…
The basic concept of sustainable drainage development is to increase water use, minimize losses and improve and conserve the environment. Principally, through Eco drain, flood / inundation or drought can be minimized because more rain water seeps into the ground which is useful as groundwater conservation. This study aims to (1) analyze the existing condition of drainage channels in Pekanbaru C…
The fires of land and forests in Riau Province lasted quite a long time and were difficult to extinguish because of the many fires on the land and forest. The most hotspots due to land and forest fires were monitored in Pelalawan District with 115 hotspots. This study analyzes 1) patterns of empowerment, supervision, and action to create sustainable and sustainable forests, 2) land and forest f…
This research was conducted from January to July 2018, in 4 districts of rice production centers in Siak Regency.

The Tampan District area is divided into nine villages. The su…
Forests have enormous services for the survival of living things, especially humans. One of the services of forests is to take carbon dioxide (CO2) from the air and replace it with oxygen (O2) needed by other creatures through photosynthesis. Forests are called the lungs of the world, if too much forest is damaged, there won't be enough oxygen to breathe. Climate change is a global phenomenon c…
Based on the 2000 Global Water Supply and Sanitation Assessment Report released by WHO / UNICEF, there are around 1.1 billion people in the world who still lack clean water and nearly 2.5 billion people do not have access to sanitation facilities. More than 100 million Indonesians lack access to clean water and 150 million contaminated water sources. The difficulty of the availability of clean …
