Abstract

Debris has long been a worrying problem, especially in the marine environment. Human activities and marine tourism activities cause coral reef ecosystem damage. The research was carried out in June - September 2022 to determine the type and abundance of marine debris, lifeforms, and condition of coral cover, as well as the relationship between the abundance of marine debris and coral cover on Pasumpahan Island, West Sumatra. The research method used was a survey, and the data obtained was analyzed descriptively. The research location was divided into three observation stations by placing three transects at each station. Based on the research results, six types of marine waste were found, with abundance ranging from 0.01 to 0.085 units/m2. The coral lifeforms found are Acropora branching, Acropora encrusting, Acropora submassive, Coral encrusting, Coral foliose, Coral millepora, Coral mushroom, and Coral massive, with a percentage of live coral cover ranging from 1.00-36.48%. A strong negative relationship exists between the abundance of marine debris and the percentage of coral cover in Pasumpahan Island, West Sumatra.

Abstract

Kegiatan ini dilaksanakan pada bulan 10 Mei – 25 Juli 2019 di Balai Benih Ikan Ryan Farm, Limbungan Rumbai yang diikuti oleh petani ikan, mahasiswa kukerta terintegrasi dan tim pengabdian yang berjumlah 20 orang. Tujuan Kegiatan Pengabdian ini adalah untuk meningkatkan pengetahuan dan ketrampilan petani ikan tentang budidaya cacing sutra, sehingga tidak tergantung lagi kepada musim di alam. Sedangkan manfaatnya diharapkan dengan pengetahuan dan ketrampilan yang diperoleh oleh peserta maka dapat memanfaatkan unit pembenihan Ryan Farm untuk pengembangan budidaya cacing sutra sampai memproduksinya akibatnya tentu produksi larva ikan dapat meningkat yang akhirnya dapat meningkatkan income bagi masyarakat setempat. Kegiatan praktek budidaya cacing sutraini dilakukan langsung oleh para peserta. Dimulai dengan praktek pembuatan media cacing sutra kemudian dilanjutkan dengan budidaya cacing sutra diwadah baskom tahu ukuran 35x28x11 cm selama 3 minggu. Hasil yang diperoleh adalah setelah dilakukan penyuluhan dan pelatihan maka berdasarkan kuisioner yang diajukan ternyata terjadi peningkatan pengetahuan masyarakat petani ikan tentang budidaya cacing sutra 90% sedangkan setelah dilakukan budidaya cacing sutra selama 3 minggu maka diperoleh cacing sutra seberat 109 g/wadah. Permasalahan yang ditemui selama praktek adalah tumbuhnya populasi cacing darah di wadah media budidaya cacing sutra.

Abstract

Ibu rumah tangga merupakan potensi tersendiri untuk pengembangan ekonomi dan nutrisi keluarga. Ikan lele dumbo memiliki rasa gurih dan telah menjadi bagian dari menu masyarakat Riau. Di sisi lain, ikan ini relatif mudah dibudidayakan, tahan terhadap lingkungan ekstrim bahkan di daerah sempit tanpa perlu air mengalir. Kegiatan ini bertujuan membina ibu rumah tangga untuk memelihara ikan lele dumbo di dalam drum, membuat pakan ikan lele sendiri dan memproses sebagian dari hasil panen mereka. Program ini diadakan di Kampung Minas Barat, Kabupaten Siak, Riau dengan menggunakan metode demonstrasi langsung. Para peserta diajari cara membuat pakan ikan, budidaya ikan lele dan kegiatan pasca panen. Dimulai dari pembentukan kelompok dan pengangkatan ketua dan sekretaris. Dilanjutkan dengan kegiatan tatap muka, praktik langsung membuat pakan ikan, persiapan wadah tumbuh, penebaran benih ikan dan pemeliharaan. Setiap peserta diberikan 1 unit drum bervolume 200 L, 300 ekor bibit ikan dan sejumlah pakan ikan lele yang mereka produksi sendiri. Satu unit mesin pembuat pelet diserahkan kepada kelompok ini. Kegiatan pemantauan dilakukan terus menerus dengan setiap 2-3 minggu, baik melalui kunjungan langsung atau melalui telepon. Peserta binaan terlihat serius, antusias dan rajin dalam menjalankan program ini. Sampai di akhir kegiatan ikan sudah mulai dipanen dan dikonsumsi oleh anggota keluarga sendiri. Dilihat dari perspektif penguatan ekonomi keluarga dan peningkatan gizi rumah tangga, kegiatan ini dianggap cukup baik dan diharapkan ditiru oleh anggota masyarakat lainnya.

Abstract

Microplastics are particles that have a size of <5 mm and their existence might be able to contaminate the biota in the aquatic environment, such as care fish. Caru fish was collected in the Dumai city fish landing base in September - December 2022 to determine the abundance of microplastics in caru fish. The method used in this study is a survey method; samples of caru fish were obtained from Fish Landing Base (PPI) Dumai, and the samples were analyzed for the microplastic content in the laboratory. The samples used were 90 caru fish divided into three size classes. The parameters measured included type of microplastic, microplastic abundance, microplastic colour and the relationship between care fish size and microplastic abundance. The abundance of microplastics from the three size class of fish shows that the size class 22.1-24 cm had a higher average abundance of microplastics with an average value of 5.7 particles/individual. The type of microplastics found in this study were fibre, film and fragment. The relationship between the length of the caru fish and the abundance of microplastics has not been influenced by the size of the carp fish.

Abstract

Research on the population structure of bamboo shells (Solen lamarckii) in the intertidal zone of Sri Tanjung Village, Rupat District, Bengkalis Regency was carried out in October 2021-March 2022. This study aimed to determine the population structure of bamboo shells and the relationship between the size of bamboo shells and the depth of bamboo shells in the sediment. The intertidal zone is divided into 5 subzones. Each subzone is placed in 3 plots measuring 1 x 1 m2 along the transect line as a replication by drawing a straight line from the boundary of the highest tide area to the lowest low tide area. The results showed that the average population density of bamboo shells was 1.20 ind/m2 or 12,000 ind/ha with the lowest density located in the highest tide area and the highest density located in the lowest low tide area. The distribution pattern of bamboo shells is uniform. The size of the most common bamboo shells found is 5.14-5.70 cm. The relationship between the size of the bamboo shells and the depth of the bamboo shells in the sediment is very weak.

Abstract

Community structure is a concept that studies the composition of species and abundance in a community. This research was conducted in April 2022 in the waters of Tidung Island, Seribu Islands Regency. The purpose by conducting this study was to determine the structure of the bivalve community which includes species, density, relative density, diversity, uniformity, dominance, distribution pattern and index of similarity. The research method used in this study is survey method, were carried out at 3 stations, station determination using purposive sampling method taking into account the anthropogenic conditions in the study area. Based on results, types of bivalves found consisted of 6 species of bivalve. The species most commonly found is Atrina pectinata. The abundance of bivalve obtained ranged from 2.67 – 5.47 ind/m2. The results of the ANOVA test between observation stations obtained the value of sig. <0.05, so it can be concluded that the density of Bivalvia between stations was significantly different, except for stations I and III. The distribution pattern of bivalves in the waters of Tidung Island is in groups. The value of the Diversity Index in the study area is classified as moderate (2.06 – 2.12). The uniformity index value during ranged from 0.80 – 0.82 wich is included in the balanced category. The dominance index between stations is different with a value range of 0.25 – 0.28 which means that no species dominates at each station.
