Abstract

This research was conducted in January 2022 in the coastal waters of Tanah Merah Village and at the Marine Biology Laboratory and Marine Chemistry Laboratory, Department of Marine Science, University of Riau. The purpose of the study was to analyze the structure of macrozoobenthos communities in the coastal waters of Tanah Merah Village which includes the type, abundance, diversity, uniformity, dominance index, and similarity of communities. As supporting data in this study, several environmental parameters were also measured which included water quality, sediment type, and sedimentary organic matter content. The research method used is the survey method, where sampling using the squared transect method is carried out at 3 stations. Based on the results of the study found 13 species of macrozoobentos. A species that is found at all stations is Nerita articulate. The abundance of macrozoobenthos is 12,300 ind/ha. The diversity index value (H') of 1.42, indicates a moderate category, namely water quality is still maintained, a uniformity index (E) of 1.66, is classified as a high category, namely water quality is still supportive for macrozoobenthos life, the dominance index (C) 0.17, is included in the low category. In the community similarity index between I and II, 25% of types are not the same, inter-station I and III 43% of types are almost the same, and inter-station II and III 16% of types are not the same. Water quality parameters are as follows: temperature 27-29oC; salinity 30-31 ppt; pH 6-7; DO 3.6-7.6 mg /l. Sedimentary organic matter 4.47-23.53%, muddy sediment type. Based on the value of the aquatic quality biological index at the research site, it is still in good condition.

Abstract

This study was conducted from January to February 2021 in coastal areas of Bengkalis Regency that is in Riau Province. This study aims to know the coastline changes to the potency of mangrove forests in that area. Field data was collected by survey methods such as direct observation and questioners, and it used different times of satellite imageries to find out the coastline changes over time. The results showed that the coastline of this regency had changed as much as 1036 Ha in average from the year of 1988 to 2020. It was due to coastal abrasion, wave actions, and reduction of mangrove forests; the coastline change reached 12.02 meters per year as the highest. The mangrove forest in the region of this regency plays important roles to the local life, the local economy, and the coastal waters; it was for fishermen, charcoal production, coastal tourism, and transportation as well.

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.
ANALYZING THE RELATIONSHIP BETWEEN THE IOD (INDIAN OCEAN DIPOLE) AND ENSO (EL NIÑO–SOUTHERN OSCILLATION) ON SEA SURFACE TEMPERATURE AND RAINFALL VARIABILITY IN THE WATERS OF WEST SUMATERA Maatitawaer, Natasya Debora C; Rifardi, Rifardi; Ilahi, Ilham; Mubarak, Mubarak; Tanjung, Afrizal; Basiluddin, Fadhlan

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.
