Abstract

Desa Buruk Bakul yang terdapat di wilayah pesisir Pulau Sumatera merupakan penghasil ikan laut di daerah Kabupaten Bengkalis Provinsi Riau. Beberapa jenis ikan ekonomis penting seperti ikan terubuk (Tenualosa macrura), tenggiri (Scomberomorus commerson), debuk (Arius thalassinus), biang (Septipina sp), dan lomek (Harpodon nehereus) diperoleh dari hasil tangkapan nelayan di desa tersebut. Ikan-ikan tersebut biasanya dijual dalam bentuk segar, namun jika tidak habis terjual, sebagian hanya diolah menjadi ikan kering dan kerupuk ikan. Kegiatan pengabdian kepada masyarakat (PKM) ini bertujuan untuk meningkatkan keterampilan kelompok Ibu Rumah Tangga (IRT) nelayan di Desa Bukit Batu dalam mengolah ikan-ikan seperti ikan tenggiri menjadi produk yang lebih bervariasi seperti bakso, nugget dan stik ikan. Program ini dilakukan dalam tiga tahapan, yaitu (1) pendekatan dan sosialisasi program, (2) pelatihan dan peningkatan kompetensi, dan (3) pendampingan kelompok, monitoring dan evaluasi. Kegiatan PKM melibatkan 25 IRT nelayan (60%) dan ibu-ibu rumah tangga lainnya. Pelaksanaan kegiatan juga dibantu oleh 10 orang mahasiswa KKN Terintegrasi UNRI 2023. Berdasarkan kegiatan PKM diperoleh hasil adanya peningkatan pengetahuan dan keterampilan peserta (85%) setelah mengikuti pelatihan tentang teknik diversifikasi olahan ikan. Hasil monitoring dan evaluasi menunjukkan bahwa 100% peserta program menyatakan program PKM sangat bermanfaat. Dari analisa keberlanjutan program menunjukkan bahwa terdapat 2 jenis pelatihan yang diinginkan oleh peserta, yaitu (1) pengolahan jenis olahan berbasis ikan yang lain, dan (2) pembuatan rancangan kemasan produk.

Abstract

The identification of Vibrio sp. bacteria in the water of intensive and traditional ponds for vannamei shrimp in Teluk Pambang Village was conducted from March to June 2023. The aim of this research was to calculate the quantity of Vibrio sp. bacteria, understand the morphological characteristics, and identify the various types of Vibrio sp. bacteria in the water of intensive and traditional ponds for vannamei shrimp. The sampling involved collecting water from 2 bottles each from intensive and traditional ponds. Subsequently, Vibrio isolation from the water was cultured on selective TCBS media through three dilution steps. The bacterial count was then determined. Further, bacterial cultures from different colonies were streaked on TSA media, followed by identification through a series of morphological observations and biochemical tests. The research results indicate that the presence of Vibrio bacteria in intensive ponds complies with the maximum threshold and quality standards for a favorable environment for both the pond and shrimp. However, for traditional ponds, there is an abundance of Vibrio bacteria exceeding the threshold, where the maximum limit or good quality standard for Vibrio in the environment and shrimp is 103 CFU/ml. The morphological characteristics found include a round shape, green and yellow color, and a flat edge with emerging elevations. Furthermore, infections of Vibrio hollisae, Vibrio anguillarum, and Vibrio damsela were identified in the water of intensive and traditional ponds for vannamei shrimp (Litopenaeus vannamei) in Teluk Pambang Village, Bengkalis Regency.

Abstract

The study on carbon reserves in sediment within Pangkalan Jambi Village, Bengkalis Regency's mangrove ecosystem, was conducted from June to 2024. This research aimed to analyze carbon reserves in the sediment of the mangrove ecosystem in Pangkalan Jambi Village, Bengkalis Regency, Riau Province. The study employed field survey methods and laboratory analyses, focusing on three stations with varying mangrove densities. Results revealed nine mangrove species, dominated by Rhizophora mucronata. The average mangrove density was 2,611 individuals/ha, with a carbon reserve of 43.25 tons/ha across all stations. The study found a positive correlation (r = 0.528) between mangrove density and carbon reserves, explaining 27.98% of the total variation. Furthermore, carbon reserves showed no significant differences across sediment depths. These findings emphasize the importance of mangrove conservation for carbon storage, contributing to climate change mitigation. Further biomass and species-specific carbon storage research is recommended to optimize mangrove management strategies.

Abstract

Vaname shrimp is one of Indonesia's leading export species and is widely cultivated. The main problem in vaname shrimp pond cultivation is the attack of shrimp diseases caused by bacteria or viruses. This study aims to isolate and identify lactic acid bacteria (BAL) from vaname shrimp (Litopenaeus vannamei) and test their antagonism against pathogenic bacteria. The research was conducted from February to April 2023. The method used in this study is a survey method. Sampling was conducted at the vaname shrimp pond of the Fisheries Service Task Unit (UPT), Tanjung Punak Village, Rupat Utara District, Bengkalis Regency, Riau. The method used in this research was a survey method. BAL was isolated using MRS Agar + CaCO3 media. The Kirby-Bauer method was used to test bacterial antagonism against pathogenic bacteria. Based on the identification of seven isolates, it was found that only four isolates were positively identified as LAB bacteria, namely 47D, 54T1, 73DB1, and 73BD2. The results of the antagonism test against pathogenic bacteria showed that all BAL isolates could not suppress the growth of E. coli bacteria. However, these isolates suppressed the growth of A. hydrophila bacteria, with the widest inhibition zone diameter on isolate 54T1 (4.2 mm). On Vibrio sp. bacteria, the widest inhibition zone of BAL was on isolate 73DB1 (6 mm). These results indicate that the antibacterial activity produced by BAL is still relatively weak.

Abstract

Vannamei shrimp (Litopenaeus vannamei) is a fishery commodity widely cultivated in various parts of Indonesia. The main problem often found in vannamei shrimp production is poor water quality during the rearing period. This study aims to isolate and identify E. coli contained in water, sediment, and meat of vannamei shrimp cultivated in shrimp ponds and examine its sensitivity to antibiotics. The research was conducted from March to May 2023 at the Technical Implementation Unit (UPT) Vannamei Shrimp Ponds of the Maritime Affairs and Fisheries Service, Tanjung Punak Village, Rupat Utara District, Bengkalis Regency, Riau. The survey method was used in this study. The Most Probable Number (MPN) method was employed for E. coli isolation to calculate bacterial density, and the Kirby-Bauer method was used to test bacterial sensitivity to antibiotics. Based on the identification of the six isolates carried out, it was found that only two isolates were positively identified as E. coli bacteria, namely SD C 3.1 and IP B 1.1, which were isolated from sediment and the Wastewater Treatment Plant (WWTP) pond. The diameter of the inhibition zone for sediment isolate RF01 against the antibiotic chloramphenicol was 18.75 mm, indicating intermediate sensitivity. On the other hand, WWTP isolates RF02 exhibited an inhibition zone of 17 mm for chloramphenicol, indicating medium sensitivity as well. However, it showed resistance to penicillin with a diameter of 6.5 mm and resistance to ampicillin with a diameter of 2 mm.

Abstract

Organic matter is one indicator of environmental fertility both on land and at sea. The content of organic matter in a certain amount can be useful for aquatic biota, but if the amount of organic matter exceeds the assimilation capacity of the waters, it can cause a disturbance. This study aims to determine the organic matter content of water and sediment at high and low tide conditions in the waters of the east coast of Bengkalis Island and to determine the relationship. The method used is a survey method that is carried out in the field directly to collect data and samples, which are then taken to the laboratory for analysis. The results showed that the organic matter content of water at high tide was 17.38-25.28 mg/L and at low tide, it was 29.63-35.55 mg/L. The organic matter content of sediments at high tide conditions ranged from 2.28-5.37% and at low tide, conditions ranged from 3.46-8.62%. These conditions indicate that the organic matter content of water and sediment has not passed the predetermined threshold. The results of the analysis of the relationship between the organic matter content of water and sediment at high tide conditions with a coefficient of determination (R2) of 0.533 with a correlation coefficient (r) of 0.730 and at low tide with a coefficient of determination (R2) of 0.713 with a correlation coefficient (r) of 0.844. The type of sediment that dominates the waters of the East Coast of Bengkalis Island is mud.
