Abstract

Macrozoobenthos has an important role in ecological functions in mangrove ecosystems which can be used as bioindicators in aquatic ecosystems. The purpose of this study was to inventory macrozoobenthos, water quality and substrate found at the study site. The method used in this study was the observation transect method of mangrove vegetation measuring 10 x 10 meters in which 5 sub-plots were made in the plot where each sub-plot measuring 1 x 1 meter. Macrozoobenthos samples were taken from the substrate, stems and roots of mangroves. Measurements of water quality parameters were taken in situ at each research station and the substrate was taken using a shovel and then observed for sediment particles in the Dumai Maritime and Fisheries Polytechnic laboratory. This study succeeded in infentarizing the macrozoobenthos of the Mollusc Phylum, class Gastropods with 6 families and 6 species (Nerita articulata, Chicoreus capucinus, Littorina scabra, Ellobium aurisjudae, Cerithidae quoyii and Pugilina cochlidium) and class Bivalvia, 1 family and 1 species (Polymesoda bengalensis). Water quality parameter values consist of an average temperature of 29.73 ˚C, a salinity of 26.33 ppt, dissolved oxygen (DO) 4.92 mg/l and a pH of 6.9. This water quality condition can still be tolerated by mangrove and macrozoobenthos plants. Substrate texture at stations 1 and 2 includes the clay loam category and station 3 the sandy loam category which has an influence on the abundance of macrozoobenthos.

Abstract

There is still minimum information on the condition of the mangrove ecosystem, such as canopy cover and vulnerability of the ecosystem. Therefore, it was necessary to analyze that by assessing the Important Value Index (INP), canopy cover and vulnerability to degradation. The primary data needed are the type, density, frequency and basal area of mangroves obtained by the Transect Line Plot (TLP) method. The canopy cover was obtained using the Hemispherical Photography method. The data analyzed using INP, pixel analysis with binary images and compared to standard criteria of mangrove damage and vulnerability to degradation of mangrove ecosystems. This study identified 5 types of mangroves, Avicennia alba, Rhizophora apiculata, Rhizophora mucronata, Xylocarpus granatum and Sonneratia alba. Xylocarpus granatum was the species with the highest INP at stations 1 and 2, while at station 3 it was Avicennia alba. Station 1 has the highest canopy cover with a value of 86%. The condition of the mangrove ecosystem in Dumai is generally in the good category with medium stands. In addition, the level of vulnerability to mangrove degradation in can be categorized as low vulnerability. Although this research was conducted with simple methods and equipment, the results can provide an overall illustration of the condition of the Dumai’s mangrove ecosystem, making it easier for interested parties to manage the ecosystem.

Abstract

Purse seine catches that have high economic value are big pelagic whose distribution of fishing areas and landing sites are poorly known. This study aims to find out the distribution of large pelagic purse seine catches based on WPP and their landing ports. The data used is data of purse seine catch from the Ministry of Maritime Affairs and Fisheries of the Republic of Indonesia in 2019 and 2020 to be analyzed descriptively. The results showed that four big pelagic species caught by purse seines: tuna (Thunnus sp.), mackerel (Scomberomorus commerson), marlin (Istiophorus platypterus) and swordfish (Xiphias gladius). Tuna is caught in all WPP and landed at 62 fishing ports. Mackerel was also caught in all WPP and landed at 74 fishing ports. Marlin were caught at 10 WPP and landed at 27 fishing ports. Swordfish were caught in 4 WPP and landed at 5 fishing ports. Knowledge on distribution of big pelagic purse seine catches based on WPP and landing ports can be used as a basis for evaluating measured fishery policies in terms of catch landing relating to fishing areas.

Abstract

Fishermen play a crucial role in the 2016 national action plan for terubuk. Accordingly, conducting a study on fishermen is imperative. The primary objective of this research is to discern the characteristics and knowledge of local fishermen pertaining to terubuk. The employed method involved conducting interviews with 30 fishermen who specialize in catching terubuk. The collected data underwent descriptive quantitative analysis. The research findings revealed that all respondents were within the productive age range, and those engaged in supplementary occupations outnumbered the Bengkalis minimum salary. Local respondents exhibited a commendable level of knowledge, demonstrating an ability to articulate scientific concepts accurately, although utilizing diverse linguistic styles. In conclusion, this study posits that fishermen perceive the necessity of exploring alternative livelihoods that leverage their local knowledge. The expectation is that this approach can not only augment fishermen's income but also contribute to terubuk conservation endeavors.

Abstract

There are several types of purse seine in Sibolga, namely tuna trawls, snare seines and meeting trawls. The main catch from purse seine is pelagic fish. Purse seine catches are related to the mesh size of the fishing gear. The mesh size is small so it can catch more than 3 species of catch which are classified as non-environmentally friendly fishing gear. The aim of this research is to find out whether purse seine fishing gear in Sibolga is environmentally friendly fishing gear or not. The research was conducted March 1 – June 30 2021 at the Sibolga Fishing Port (PPN), The research was carried out at KM Samosir 08 on cob trawl fishing gear and KM Serasi Putra on cob trawl fishing gear. The data analysis used is a scoring analysis of environmentally friendly fishing gear criteria. Trawls and cob trawls are environmentally friendly fishing gear and meet the 9 criteria for environmentally friendly fishing gear. The score for the level of environmental friendliness of the tuna trawl fishing gear was 33 and the meeting trawl was 32.6 with the criteria being included in the group of very environmentally friendly fishing gear.

Abstract

Macrozoobentos are known as organisms that are sensitive to environmental changes, so they are widely used as biological indicators of a water. This study aims to determine the types of macrozoobenthos, the level of diversity, uniformity, and dominance of macrozoobenthos, including the family biotic index (FBI) to detect water quality in Dumai City. The method used was a survey with stations determined through the purposive sampling. Macrozoobenthos samples were collected using a line transect with a square transect and a core sampler. A total of 381 macrozoobentos individuals found in the waters of Dumai City consisted of 6 species from the Gastropods class (Nerita articulata, Chicoreus capucinus, Littorina scabra, Ellobium aurisjudae, Cerithidae quoyii, and Pugilina cochlidium); Bivalvia class: 1 family and 1 species (Polymesoda bengalensis). The highest macrozoobenthos density was found at Station 3 (125 ind/m2) and the lowest at station 1 (21 ind/m2). The Shannon-Wienner diversity index ranged between 1.17 and 1.52. The diversity index at all stations was relatively low, the macrozoobenthos uniformity index was high (0.654697-to 0.783512), and the dominance index was relatively low (0.234078-to 0.43574). The Shannon-Wienner Index and the dominance index are also relatively low. Further testing using the FBI showed differences in water quality: Station 1 was adequate, Station 2 was poor, while Station 3 was somewhat poor. Monitoring macrozoobenthos diversity can be helpful in detecting changes or disturbances in ecosystems. Keywords: bioindicator, diversity, Family Biotik Index, macrozoobenthos

Abstract

Penetapan Suaka Perikanan Terubuk (SPT) berdasarkan Peraturan Bupati Bengkalis No. 15 Tahun 2010 dan Keputusan Menteri Kelautan dan Perikanan No. KEP.59/MEN/2011 tentunya memberikan dampak sosial dan ekologi yang positif. Penelitian ini bertujuan menilai manfaat sosial dan ekologi SPT bagi masyarakat pesisir di Perairan Bengkalis, Riau. Data diperoleh melalui wawancara dan analisis produksi perikanan berdasarkan ketersediaan data dari tahun 2008-2016. Keberadaan ikan terubuk di perairan Kabupaten Bengkalis, Kepulauan Meranti dan Siak lekat dengan nilai sejarah dan budaya. Hasil dari pemodelan peramalan produksi selama 10 tahun menunjukkan penurunan produksi ikan terubuk, dengan prediksi penurunan 1,37 ton per tahun (-0,58%) berdasarkan model S-Curve. Hasil analisis statistik (t-test) juga menyebutkan tidak ada pengaruh antara sebelum dan setelah diterbitkannya SK (Peraturan Larangan Terubuk) dengan melihat nilai P-Value > 0,005. Secara umum, pengelolaan perikanan Terubuk yang ada di Perairan Provinsi Riau belum efektif dengan hanya diterbitkannya SK pengelolaan Kawasan, akan tetapi diperlukan beberapa langkah strategis diantaranya adalah dengan meningkatkan peran Masyarakat dalam pengelolaan, peningkatan pengawasan dan penegakan hukum dalam melakukan konservasi perikanan Terubuk.
