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

The waters of Lubuk Gaung Village, Sungai Sembilan District are areas that are widely used as transportation routes. Activities in these waters will cause environmental pollution, which affects the life of phytoplankton. The purpose of this study was to determine the relationship between the primary productivity of phytoplankton with oceanographic parameters in the waters of Lubuk Gaung Village, Sungai Sembilan District, Dumai. The method used is the survey method to determine the research station and the in situ method for measurement and sampling of oceanographic parameters. The results obtained are Oceanographic parameters from the three research stations, namely Brightness = 30 – 49 cm, Turbidity = 47.4 – 58.4 FTU, TSS = 124 – 209 mg/L, and BOD = 0.408 – 1.224 mg/L. The average value of primary productivity of the waters ranged from 48.07 to 79.69 mgC/m3/day. The value of primary productivity at station II is categorized into Oligotrophic, namely low waters. Stations I and III are categorized into mesotrophic waters, namely medium waters. The relationship between brightness, turbidity, and TSS with primary productivity has a very strong and positive (unidirectional) correlation value. The relationship between BOD and primary productivity has a very strong and negative (opposite) correlation.

Some studies say the pollution level in the waters oil industry in Dumai City, Riau. The level of pollution that occurs will affect the abundance of macrozoobenthos. This research aims to know the concentration of oil and heavy metals in sediments in the waters around the area of the Dumai City oil industry, knowing the effect of oil on the abundance of macrozoobenthos. This research method includes placement of research stations, observation and sampling, TSS sample analysis method, concentration oil in sediment samples, heavy metal concentrations of Pb, Cd, and Cu at sediment samples, macrozoobenthos abundance Analysis, and data analysis. Results research average concentration of oil in sediments in water areas The oil industry of Dumai City, Riau, has passed the threshold that has been set determined by the Department of Water Resources Quality Assurance/Quality Control Program That is > 1000 ppm, so it can be said that station 1 up to 9 are polluted and harmful to organisms that live on the bottom those waters relationship of oil concentration, heavy metals (Pb, Cd, and Cu) moderate to weak.

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.

Beberapa aktivitas seperti bongkar muat kapal dan juga pencucian mesin kapal yang terjadi di perairan dapat memberikan dampak negatif. Salah satunya minyak. Minyak yang mengapung pada permukaan air dapat menyebabkan air berwarna hitam dan akan mengganggu organisme yang berada pada permukaan perairan, maka secara langsung akan mengurangi laju produktivitas primer pada perairan pesisir Kota Dumai. Tujuan dari penelitian ini yaitu menghitung nilai konsentrasi minyak, mengetahui tingkat produktivitas primer, dan mengetahui hubungan produktivitas primer fitoplankton dengan kandungan minyak di perairan pesisir Kota Dumai. Adapun metode yang digunakan adalah metode Purposive sampling, pengambilan sampel air untuk uji kandungan minyak dan untuk uji produktivitas primer pada tiga stasiun yaitu, daerah jauh dari aktivitas penduduk, daerah pelabuhan dan daerah industri. Hasil yang didapatkan yaitu nilai rata-rata produktivitas primer perairan dari ketiga stasiun penelitian berkisar antara 48,4 – 94,9 mgC/m3/hari. Nilai produktivitas primer tertinggi terdapat pada stasiun I dan nilai produktivitas primer terendah terdapat pada Stasiun II. Produktivitas primer memiliki korelasi yang kuat dan negatif (berlawanan) dengan Minyak.

This study is to determine the relationship between primary productivity and nutrients in the coastal waters of Pelintung Village, Medang Kampai District, Dumai. The research was conducted in March 2022; the method used in this research is survey method and purposive sampling. The research location is divided into 3 station points namely tourist area, secondary vegetation forest area, and near industrial area. The results of the measurement of the highest primary productivity value are found at Station III which is 78.91 mgC/m2/hour which indicates mesotrophic water conditions, while the lowest primary productivity value is at Station II, which is 46.88 mgC/m2/hour which indicates oligotrophic water conditions. The results of the analysis of the concentration of nitrate and phosphate between stations also varied, namely for the nitrate value of 0.04 – 0.05 mg/L which was included in the less fertile category, while the phosphate concentration was 0.042 – 0.048 mg/L which was included in the fertile category in the waters. Furthermore, the relationship between nitrate concentration and primary productivity is a correlation coefficient value (r) = -0.070 which means that there is a weak relationship between nitrate concentration and primary productivity. Meanwhile, the relationship between phosphate concentration and primary productivity is the correlation coefficient (r) = 0.965, which means that there is a very strong relationship between phosphate concentration and primary productivity. So it can be concluded that nitrate and phosphate nutrients can affect the primary productivity of water.
