Abstract

Changes in land cover are the most important factors causing global environmental change. This land cover change causes an increase in gases, especially CO2 gas in the atmosphere, thus becoming one of the causes of carbon gas emissions. The study site is located in Pekanbaru City which is the capital city of Riau Province with a relatively rapid rate of regional development because it is a strategic area. The purpose of this study was to analyze the land cover change of Pekanbaru City in the period 2011–2020 and analyze the value of carbon emissions resulting from changes in land cover. The method used to analyze the value of carbon emissions is the IPCC method. In 2011, the largest land cover was dry land agriculture with an area of 27,31%, plantations covering an area of 24,76%, and settlements covering an area of 24,54% of the entire Pekanbaru City. In 2020, the area of dry land agriculture decreased drastically to 0%, while plantations experienced a fairly high increase in area to 36,07%, and settlements also experienced an increase in area to 51,32%. As a result of land cover changes in Pekanbaru City, for 10 years the estimated value of carbon sequestration is higher than the value of carbon emissions. The carbon absorption value of Pekanbaru City in the 2011–2020 period is 4,879,901,455 tons CO2-eq, while the carbon emission value of Pekanbaru City in the 2011–2020 period is 710,370,804 tons CO2-eq. The highest carbon stock value for each land cover class in Pekanbaru City for the 2011–2020 period, was in 2020 with a carbon stock value of 2,413,271 tons/year.Keywords: carbon absorption, carbon dioxide, carbon emissions, land cover change, Pekanbaru city.

Abstract

Restaurant waste is biomass which has the potential to be developed into renewable energy in the form of biogas. The choice of restaurant waste is the main substrate for biogas production because the waste contains many elements of organic material which have not been widely used, especially for biogas production. Besides of restaurant waste, tofu liquid waste and cow dung are very potential to be used as additional substrates in the biogas formation process. This research aims to study the effect of variations in the composition of organic waste (restaurant waste, tofu wastewater and cow dung) on the quality of methane gas in biogas production. The research was conducted using an 30-liter anaerobic biodigester with a working volume of 22.5 liters. The research variables are substrate variations, namely 100% restaurant waste, 50% restaurant waste : 50% tofu liquid waste, and 93.75% restaurant waste : 6.25% cow dungThe results showed that the initial pH value of the three biodigesters ranged from 6.63 to 6.7 where the pH range was still within the ideal pH value in making biogas, which ranged from 6.6 to 7.6. While the temperature of each reactor in this study has fluctuated, ie 28 ° C - 29.7 ° C, in this temperature range biogas can still be developed.

Abstract

Transportation problems are a problem that is often faced by developed countries and developing countries such as Indonesia, both in the fields of urban transportation and inter-city transportation. The high growth rate of motorized vehicles, on the one hand, can encourage economic growth, but on the other hand it can cause environmental impacts including congestion and noise. The increase in the flow of vehicles in the city of Pekanbaru is not only seen in the middle of the city but can be seen in the Districts of Rumbai and Rumbai Pesisir which are development areas (WP) II and WP III caused by densities of settlements in the two regions as well as several private universities such as the Caltex Riau Polytechnic (PCR), Lancang Kuning University (UNILAK), recreational areas, markets and other shopping centers. The method used manual traffic counting is to use a manual counter tool and survey form sheets to calculate the number of vehicles passing directly at the research location. The results showed that the highest number of vehicles on the three roads that became the vehicle research sample in WP II and WP III based on peak times namely on Yossudarso Road occurred on Monday afternoon at 40,105 SMP / day, School Roads occurred on Saturday Afternoon at 36,363 SMP / day, and on Jalan Tegalsari the highest number of vehicles occurs on Monday Morning at 5,161 SMP / day.

Abstract

The increase in vehicle ownership causes transportation activities to increaase. The tendency to increase the number of motorized vehicles operating, will add to the burden of traffic one example is the increase in noise intensity. This study aims to map the pattern of noise distribution and to determine the level of noise that occurs in Jenderal Sudirman street Pekanbaru city by taking data in the form of noise data and several other traffic variables such as vehicle volume and speed. This research was conducted using a Sound Level Meter (SLM) and with a noise mapping method for 2 days, namely on Monday which represents peak hours and Saturdays which represent vehicle quiet hours. The results showed that from 180 measurement points the highest noise level was 97.9 dB which was a point with high traffic volume and the lowest noise level was 68.4 dB which had low traffic volume. Comparison of noise level with KepmenLH No.48 / MENLH / 11/1996 quality standard results obtained 4 points in the Sukaramai Market. Noise mapping using the ArcGis 10.3 software program.From this study it can also be concluded that the greater the volume of the vehicle, the vehicle speed will be lower so as to produce a high noise level, and vice versa so that the volume of the vehicle is directly proportional to the noise level, while the vehicle speed is inversely proportional to the noise levelKeywords: Noise, Traffic, Jenderal Sudirman Street
