Abstract

Water is an environment element that is needed to support all human life. Peat water is containing a Natural Organic matter (NOM) that make it brown, taste and smelling. Peat water quality not suitable with water quality standards Permenkes No. 416/MENKES/PER/IX/1990. One of the peat water treatment methods used in this study is pre treatment of coagulation-flocculation and ultrafiltration membrane. This study aims to determine the removal efficiency of organic matter and turbidity in the pre treatment of coagulation-flocculation using coagulants Cengar Clay, coagulants Cengar Clay to decrease organic matter and turbidity, determine the performance of membrane for flux and rejection of organic matter and turbidity with and without pre treatment of coagulation-flocculation, determine decrease of organic matter and turbidity in peat water treatment using ultrafiltration membrane with pre treatment of coagulation-flocculation. The highest removal efficiency in coagulation-flocculation for organic matter parameter and turbidity obtained at a dose of 100 ml with a variation efficiency value of 47,733% dan 70,484%.

Abstract

Development Area V is the most densely populated area with an area of 32% from Pekanbaru City. Based on BPS (2017), the area Development V 140,96 km2 consists of 3 subdistricts, Tampan District, Marpoyan Damai, and Payung Sekaki. Population growth in this region is influenced by several factors, residential areas, higher education centers, city government office buildings and hospitals (RPJMD Pekanbaru, 2017-2022). The high number of residents in WP V with a variety of population activities will certainly have an effect on the resulting CO2 emissions. This research will be conducted on the calculation of the amount of CO2 emissions with IPCC (1996) method from household activities. The primary carbon emissions related to fuel use. Based on the calculation results, it was found that the primary CO2 emissions from fuel use generated in WP V Kota Pekanbaru is 3.136,1 ton CO2/month. Keywords: Household, fuel use, primary CO2 emissions

Abstract

Climate change is one of the effects of global warming caused by the greenhouse effect by increasing concentration of greenhouse gases. In response to global warming Indonesia goverment is committed to reducing greenhouse gas emissions 26% by its own effort and 41% if it receives international assistance in 2020. One of the industrial sectors that contributes to greenhouse gas emissions in Indonesia is the Palm Oil Mill (POM) . To find out the total of CO2 emissions produced uses method by Intergovermental Panel on Cilmate Change (IPCC). Total emissions from POM PT. Johan Sentosa is 115.015,18 CO2 eq/year.Keywords: Palm Oil Mill (POM), IPCC, CO2

Abstract

PT. X in its operational activities has the potential to generate noise coming from palm oil production machines. Workers who are constantly exposed to noise have the potential to affect their health and comfort. The purpose of this research is to know the intensity of noise generated by oil palm production machine, exposure time, mapping of noise distribution pattern, and noise control effort. Meteorological data includes temperature, humidity, wind speed and wind direction. Meteorological data includes temperature, humidity, wind speed and wind direction. From the measurement results of the area temperature 38 0C, while for the ISBB (wet ball temperature index) conditions at the work location must not exceed 26.7 ° C. measurement of air humidity is 80.2%, and for the provision of humidity levels of air humidity in the work environment up to 90% can be tolerated. And the results of the measurement of wind speed obtained are 1.1 m / s for wind speed itself is one of the medium of sound mediation. Keyword : Wind speed, air humidity, temperature

Abstract

Biocoagulant is a natural coagulant that has an active substance and has a role as cationic which is able to bind colloidal particles in water. Chitosan is a non-toxic, easy-to-degrade and polyelectrolyte biocogulant that can be found in crustacean animals especially in crabs (Brachyura). The availability of crab shell waste has a huge potential to be used as raw material for making chitosan. High concentration of detergent in water can cause water quality to decrease and environmental pollution in the form of increase of phosphate level, so that the previous processing is needed by using coagulation-flocculation method. The research process was done gradually starting from the extraction of crab shells to chitosan by deproteination process, demineralization, and deacetylation, followed by Coagulation-flocculation method. The study was conducted by varying the dose of coagulant by 150 mg / L, 200 mg / L, 250 mg / L and 300 mg / L. The effluent was then analyzed by the laboratory, for COD parameters referring to SNI 06-6989.2-2004, and phosphate refers to SNI 06-6989.31-2005. The result of the analysis was then compared with the PERMENLH / 5/2014 quality standard. Based on the laboratory results, after analyzing the concentration of the parameters tested, it showed that the maximum allowance of phosphate parameters were 81.84% respectively at 200 mg / L coagulant dose with stirring speed of 150 rpm for 2 min and 60 rpm for 15 min followed by deposition for 30 min.Keywords:Biocoagulant, chitosan, coagulation-flocculation

Abstract

The green open space is one of an effort in order to handling of the increasing the greenhouse gas emission, because green open space has an ability to absorbing the CO2 emission. The purpose of this research is to find out the potential of absorption capacity of CO2 by the public’s green open space and to analyze the level of absorption of CO2 by green open space from transportation activity. The method in this research is calculate the value of CO2 emissions and counting the trees which has diameters more than 20 centimeter. The sufficiency of green open space was analyze and then compared the absorbing power of CO2 by trees with number of CO2 emissions that produced. Tampan district is produced the CO2 emissions from transportation which is high enough as much as 2.102.614.367 kilograms CO2/year. While the ability of CO2 absorption by the public’s green open space in Tampan district only 7.979.245,86 kilograms CO2/year. The result of analysis show that the public’s green open space in Tampan district that viewed from absorbing CO2 emissions of transportation is still not enough with percentage is only about 0,38%.Keywords: Green Open Space, Co2 Emissions, and Greenhouse Gas
