“…Ini karena dengan kecepatan aliran sungai yang tinggi, maka semakin besar pula erosi yang terjadi di badan sungai. Erosi yang tinggi berpotensi semakin meningkatnya partikel sedimen yang akan terendapkan (Sembiring et al, 2014;Srijati et al, 2017;Ahmad et al, 2019). Aliran sungai akan bertemu dengan arus laut di bagian muara, sehingga aliran sungai akan melemah.…”

Muara Sungai Silugonggo merupakan sungai yang berada di Kabupaten Pati yang bermuara di Laut Jawa. Muara Sungai Silugonggo menjadi daerah penting karena menjadi alur pelayaran bagi nelayan di TPI Bajomulyo yang berada di sekitar muara sungai. Masalah yang sering terjadi adalah sedimentasi di muara sungai yang menyebabkan pendangkalan dan mengganggu kegiatan nelayan. Penelitian ini bertujuan untuk mengetahui kondisi arus dan laju sedimentasi di perairan muara Sungai Silugonggo. Penelitian menggunakan metode deskriptif dan lokasi pengambilan sampel ditentukan dengan metode purposive sampling, dengan jumalah 7 stasiun. Pengambilan data lapangan dilakukan pada tanggal 16 - 28 Mei 2022. Data primer berupa sampel sedimen, material suspensi, debit sungai, debit suspensi dan kecepatan arus, sedangkan data sekunder berupa data pasang surut dari BMKG Maritim Semarang. Hasil penelitian diperoleh nilai rerata laju pengendapan sedimen di perairan muara Sungai Silugonggo berkisar 0,965 kg/m2/hari sampai 1,121 kg/m2/hari. Laju pengendapan sedimen terkecil ditemukan daerah muara yang lebih menjorok ke laut dengan nilai 0,951 kg/m2/hari, sedangkan laju pengendapan sedimen terbesar ditemukan di mulut sungai dengan nilai 1,128 kg/m2/ hari. Jenis sedimen di lokasi penelitian didominasi oleh sedimen silt. Proses angkutan partikel sedimen terjadi secara suspensi yang pada akhirnya mengendap di dasar perairan ketika kecepatan aliran sungai melemah. Faktor yang mempengaruhi proses laju pengendapan sedimen di perairan muara sungai Silugonggo adalah, debit sungai, debit suspensi, pasang surut dan arus pasang surut.Kata kunci: Muara Sungai Silugonggo, Pendangkalan, Laju Pengendapan Sedimen The estuary of the Silugonggo River is a river in Pati Regency that empties into the Java Sea. The mouth of the Silugonggo River is an important area because it is a shipping channel for fishermen at TPI Bajomulyo, which is around the river mouth. The problem that often occurs is sedimentation at the mouth of the river, which causes siltation and disrupts fishing activities. This study aims to determine current conditions and sedimentation rates in the waters of the Silugonggo River estuary. The research used the descriptive method, and the sampling location was determined by the purposive sampling method, with a total of 7 stations. Field data collection was carried out on May 16–28, 2022. Primary data consisted of sediment samples, suspension material, river discharge, suspended discharge, and current velocity, while secondary data consisted of tidal data from the Semarang Maritime BMKG. The results showed that the average rate of sediment deposition in the waters of the Silugonggo River estuary ranged from 0.965 kg/m2/day to 1.121 kg/m2/day. The smallest sediment deposition rate was found in the estuary, which was more indented into the sea, with a value of 0.951 kg/m2/day, while the highest sediment deposition rate was found in the mouth of the river with a value of 1.128 kg/m2/day. The type of sediment in the study site is dominated by silt sediments. The process of transporting sediment particles occurs in suspension, which eventually settles to the bottom of the water when the river flow velocity weakens. Factors that influence the rate of sediment deposition in the estuary of the Silugonggo River are river discharge, suspension discharge, tides, and tidal currents.Keywords: Silugonggo River Estuary, Shallowing, Sediment Deposition Rate

“…At the time of the study, the weather conditions were not rainy, so the water discharge entering station 4 was relatively small at 0.021 m3/s, so the incoming suspended sediment discharge was 10.50 × 10 -4 kg/s. The large flow discharge will impact the release of suspended sediment transported by the flow, which is also increasing in size (Ahmad et al, 2019;Hutari et al, 2018). In the Pusong Reservoir, the highest turbidity was at station 4.…”

The city of Lhokseumawe often experiences flooding or stagnant rainwater. The Pusong Reservoir that was built could have been ineffective in overcoming the flooding problem due to siltation in the reservoir. Therefore, this study aims to review and recommend the management of the Pusong Reservoir based on suspended sediment discharge which is expected to overcome the silting problem of the reservoir. The sampling method was carried out by determining the stations for sampling based on the environmental baseline in determining the six reservation stations. Samples were analyzed for suspended sediment concentration, turbidity, and incoming sediment discharge. Analysis of suspended sediment concentrations ranged from 9.3 - 50.0 ppm, turbidity ranged from 2.17 - 14.42 NTU, and the incoming suspended sediment discharge was 0.00 - 6946.56 kg/day. Based on the analysis of suspended sediment discharge that enters the reservoir, it is necessary to control sediment transport to prevent siltation does not occur in the Pusong Reservoir. The management of the sediment transport control includes sediment traps, vegetative systems, and Spoil Bank Resulting from Sediment Dredging.Keywords: Suspended Sediment, Management, Pusong Reservoir, Turbidity

“…The research stations are also located in the same area, namely the Bengkalis Strait; these conditions are indicated to cause the type of sediment from the three stations to be almost the same. According to Ahmad et al 13 river flow affects the size of the floating sediment discharge value. The value of floating sediment discharge in river waters will be greater if the river flow discharge is greater.…”

Organic matter has an important role in marine ecology and it can be used as an indicator of water fertility. The content of organic matter in the waters in a certain amount can be useful for aquatic biota, but if it exceeds the acceptable threshold for the environment and organisms, it can cause disturbances. The content of organic matter in the waters will increase due to waste from households, agriculture, industry, and organic waste from land that is carried into the waters. Various community and industrial activities both on land and waters in the South of Bengkalis Island can provide input of organic matter in the waters. The method used in this research is a survey method that is carried out directly in the field to collect data and samples which are then analyzed. This study aims to determine the content of organic matter in water and sediment and analyze their possible relationship. The results showed that the organic matter content of the water ranged from 34.36 – 35.96 mg/L and the organic matter content of the sediment ranged from 4.78 – 13.78%. The content of organic matter in the waters has not exceeded the quality standard threshold. The results of a simple linear regression test showed a positive relationship with an R2 value of 0.712, which means that the relationship between the organic matter content of water and sediment is quite strong (71.2%). The types of sediment in the southern waters of Bengkalis Island are the mud type
