Abstract

Benthic epifauna are animals that generally live in coastal waters such as sandy/muddy beaches, coral reef ecosystems and mangrove ecosystems. The purpose of this study was to analyze the structure of the benthic epifauna community in Mangrove ecotourism, Pangkalan Jambi Village, Bukit Batu District, Bengkalis Regency. This study uses a survey method. Epifauna community structure parameters taken include species, abundance, diversity, uniformity, and dominance. The environmental parameters measured included water quality, substrate type and total organic matter content of the sediment. The number of species found was 9 species from 2 classes, namely Gastropods and Malacostraca with the most dominant species found, namely the benthic epifauna species Cerithidea quadrata. The highest abundance of benthic epifauna species Cerithidia quadrata was 1.04 Ind/m2. Based on the ANOVA test with a significant value of 0.115> 0.05, it means that the preference of the betik epifauna between stations was not significantly different.

Abstract

The Coastal area is an area that is very vulnerable to the phenomenon of natural change. The coastal area's vulnerability level is influenced by geological variables, namely coastal geomorphology, sea level rise, shoreline changes, tides, and coastal elevations. This research was conducted in October 2021. This study aims to determine the level of coastal vulnerability in the Dumai Barat Sub-District, Riau Province with a quantitative descriptive method. Based on the result of the study, the coastal vulnerability index can be classified into five categories: very not vulnerable, not vulnerable, medium, high, and very high. The coastal area of Dumai Barat District is categorized as low vulnerability.

Abstract

This study was conducted from July to August 2021 in coastal areas of Rupat Island, Riau Province. Coastal zone is an unstable area toward change, because it is a rendezvous place for land and sea, which the line is called shoreline. The purpose of this study was to determine the distance of shoreline change and to find out the landcover change in the coastal area. Method used in this study is a shoreline overlay from Landsat 5 in 1988, 1996, 2004 and Landsat 8 OLI in 2012 and 2020 and classifiation of land cover using supervised classification and Rupat Island monogram. This research showed shoreline changes between 1988 and 2020, abrasion of 106,55 hectares and accretion of 58,28 hectares. The largest land cover change was the decrease of dryland agriculture and forest area of 1530.80 hectares and 726.92 hectares. The largest addition of area occurred on the plantation that is equal to 741.02 hectares.

Abstract

This research examines the influence of the Indian Ocean Dipole (IOD) and El Niño–Southern Oscillation (ENSO) on sea surface temperature (SST) and rainfall variability in the coastal waters of West Sumatra over the period 2014–2024. The analysis draws on the Dipole Mode Index (DMI), Niño 3.4 index, SST, and rainfall data, processed using MathWorks and Excel. Regression analysis between field and satellite-derived SST data showed a strong correlation (R² = 0.936), confirming the reliability of satellite data for this study. Findings reveal that positive IOD and El Niño events are generally associated with cooler SSTs and reduced rainfall. In contrast, negative IOD and La Niña phases correspond to warmer SSTs and increased rainfall. The IOD appears to exert a more pronounced influence on SST variability than ENSO. Notably, the combined occurrence of a positive IOD and El Niño amplifies the decline in SST and rainfall. At the same time, the combination of a negative IOD and La Niña enhances increases in these variables. These results highlight the significant role of large-scale climate mode in shaping regional oceanographic and atmospheric conditions in the West Sumatra region.

Abstract

Peningkatan tumpukan sampah plastik terus terjadi seiring dengan perubahan pola komsumsi masyarakat yang tidak bisa lepas dari penggunaan barang berbahan plastik dalam kehidupan sehari-hari, misalnya kantong plastik. Plastik banyak digunakan dikarenakan mudah dalam penggunaannya, ringan, dan memiliki daya tahan yang lama. Hal ini juga terjadi penumpukan sampah plastik di Kawasan mangrove di Pangkalan Sesai Dumai dikarenakan masyarakat masih sering membuang sampah plastik ke kawasan perairan yang masuk saat pasang dan berdampak terhadap flora dan fauna di ekosistem mangrove. Tujuan dari penyuluhan ini adalah untuk memformulasikan pembentukan kelompok pengelolaan Bank Sampah di Kelurahan Pangkalan Sesai. Metode yang digunakan dalam kegiatan penyuluhan ini adalah metode ceramah, diskusi dan dan merancang penyusun pengelola Bank Sampah di Pangkalan Sesai. Hasil evaluasi terhadap 25 orang peserta penyuluhan menunjukkan bahwa 90% peserta belum paham tentang bagaimana tentang pengeloaan bank Sampah dan 10% faham sebatas kegiatannya saja. Setelah mengikuti kegiatan penyuluhan ini terjadi peningkatan 70% pengetahuan tentang bagaimana cara mengelola Bank Sampah. hal ini terlihat dari antusias peserta dalam tanya jawab dengan pemateri dan tingginya keinginan peserta untuk membentuk Bank Sampah dengan terbentuknya formatur kepengurusan yang terdiri Pengawas, Ketua Sekretaris. Bendahara, Devisi teknis, dan Operasional.

Abstract

The maintenance dredging work at Ulee Lheue Port aims to maintain optimal water depth for navigation activities. However, this activity involves various risks that must be systematically identified and managed. This study employs the IBPRP (Hazard Identification, Risk Assessment, and Opportunities) method to analyze potential risks in the dredging process.The analysis results indicate four major risks, consisting of two medium-level risks and two high-level risks, with no low-level risks identified. The high-level risks have the potential to significantly impact the stability of the port basin and worker safety. To mitigate these risks, strategies adhering to occupational safety standards and environmental protection measures are implemented, such as the adoption of safer dredging technologies, strict operational supervision, and workforce training.By implementing appropriate risk identification and mitigation measures, the dredging process can be carried out more safely, efficiently, and sustainably. This study is expected to serve as a reference for port management in designing more optimal and risk-based dredging strategies

Abstract

This research was conducted in February 2021 at the mouth of the Dumai River, Rupat Strait. The purpose of this study was to determine the effect of sediment supply from land on changes in bathymetry in the waters of the Rupat Strait based on the analysis of suspended sediment (SSC) and suspended solids (TSS) divided by the area of the study. The method used is a survey method. The results showed that as much as 26,94 tons/year of sediment entered the Rupat Strait and was distributed in the research area. Each part of the research area has a different bathymetric change value. This is presumably due to oceanographic factors in the waters of the Rupat Strait such as strong and weak river currents when entering the sea, the distance between the research area and the sediment supply source, human activities in each part of the study area, erosion along the river and abrasion at the river mouth. the presence of mangrove forests, dominant sediment types, sloping water topography, the cross-sectional width of the river as a sediment supplier, and suspended solids.

Abstract

This research was carried out in December 2021-January 2022 in Dumai City District, Riau Province. The purpose of this study is to determine the rate of sea level rise based on analysis of tide data from 2001-2021 and to predict inundation areas in the next 20 years. This research method is a descriptive survey using remote sensing as an additional tool to show the results. Acquisition needs are in the form of primary data (land use and tide data) and secondary (slope data, elevation, land use, and tide data). These parameters are processed and analysed to describe the extent of the inundation by displaying a map of the City of Dumai. The results showed that the waters of Dumai City have a Formzhal number of 0.5, which means that the water area is classified as a mixed tide, semi-diurnal prevalence, with a sea level rise of 2.003 cm/year. Then, the numbers used to predict the height of sea level rise in the next 20 years are 0.973 m each. Furthermore, sea level height was analyzed to obtain the inundation area for the next 20 years, it turns out that the inundation area each year is 11.89 ha.
