Abstract

Methane gas is one of the greenhouse gases that is 21 times more potent than C02. Therefore, it is necessary to estimate the quality of pollutants released by landfills around the world. The purpose of this research is to predict the amount of methane emitted from Muara Fajar 2 landfill in Pekanbaru city using Landfill Gas Emissions (LandGEM) model. AERMOD is used to model the distribution of pollutants generated by landfills. This model requires meteorological data such as temperature, temperature, wind direction, wind speed, radiation, air pressure, cloud cover, humidity and cloud base height. The meteorological parameters used in this study are meteorological data obtained from the Climate Data Store (CDS) of Pekanbaru city. The results showed that the peak of methane emissions produced by Muara Fajar 2 Landfill was 19,290 Mg/year in 2049. Pollutant dispersion showed that in 2022 Muara Fajar 2 Landfill produced a dispersion of 2447814 μg/m3. Methane gas pollutants produced by Muara Fajar 2 Landfill have no impact on the surrounding environment.

Abstract

The need for predictions is very necessary in various sectors of life, one of which is rainfall predictions. The threshold value for PM10 particles that is allowed to be in ambient air is, 150 µgram/m3/day). The aim of this research is to create a dynamic model predicting Pekanbaru City's rainfall for the next 3 years. Rainfall prediction in this research was carried out using the dynamic system modeling method with Powersim software. The data used is BMKG data for the Pekanbaru City for 5 years (2015 – 2019) using 4 parameters, namely rainfall, air humidity, wind speed and temperature. Prediction results show that air humidity in Pekanbaru City has the same pattern as BMKG, namely the highest month is December and the lowest is August. Wind speed prediction results are highest in July and lowest in May. The highest temperature in Pekanbaru City is in April and the lowest is in January. Rainfall for 2020 – 2021 is predicted to experience light rain on average, because it has the same data pattern on the variables that influence it. So it can be interpreted that the validation results for air humidity, wind speed and temperature in Pekanbaru City show that they are valid because they do not exceed the limit value of ≤ 5%.

Abstract

This research was conducted in March 2022 in the Coastal Waters of Dumai City. This study aims to analyze the amount of organic matter and the abundance of macrozoobenthos and the relationship between the amount of organic matter and the abundance of macrozoobenthos. The method used is a survey method consisting of 10 stations with 2 replications at each station. And 1 station is a control station located on the north coast of North Rupat District, Bengkalis Regency. Sediment sampling was carried out in the field and then taken to the Marine Chemistry Laboratory, Riau University for analysis of organic matter and macrozoobenthos analysis. Based on a simple linear regression test, the relationship between the amount of organic matter and the abundance of macrozoobenthos obtained a correlation value (r) = -0. 4637 with the mathematical equation y = -4.884x + 98.896. The test results show a weak and inverse relationship between the amount of organic matter and the abundance of macrozoobenthos. This means that with the increase in the amount of organic matter, the abundance of macrozoobenthos in the coastal waters of Dumai City will decrease. The value of the coefficient of determination (R2) is 0.2146. This figure shows that the

Abstract

The environmental challenges faced by Batik Bujang and Batik Candafa, two Riau-based SMEs, stem primarily from the production process, which generates substantial wastewater containing harmful chemicals. The improper disposal of these by-products poses serious risks to water bodies and surrounding ecosystems. This research aims to design a waste management system using eco-friendly technologies capable of processing up to 40 liters of wastewater, thereby minimizing environmental harm. A mixed-method approach was adopted, combining quantitative analysis of waste volume and chemical composition with qualitative insights from SME owners. The findings indicate a significant reduction in chemical pollutants post-treatment, aligning with eco-sustainability goals. This study fills the research gap by providing a technological solution specifically tailored to the needs of small-scale batik producers, emphasizing sustainability and environmental responsibility.

Abstract

Universitas Muhammadiyah Riau (UMRI), one of the campuses that supports development programs, has carried out planning and coaching students to become entrepreneurs. This can be seen from the level of participation and success of UMRI students in several student competitions, such as PKM-Entrepreneurship, P2MW, and Entrepreneurship Award. However, after the competition, many student businesses closed due to inadequate business management, equipment, and other factors. Therefore, this coaching program was carried out. The methods used are socialization, selection, provision, increasing tenant capacity (entrepreneurship training and internships), providing science and technology as well as business capital, mentoring, and evaluation monitoring. As a result of this activity, there are 20 student tenants who partner with 10 types of products. There has been an increase in tenant capacity with training, onboarding (internships), mentoring, and application of science and technology, as well as capital provided. It is hoped that this increase in tenant capacity will also improve their business skills so that their business can run well.
