Abstract

The Covid-19 outbreak has a global impact, especially in terms of the community's economy, so that those affected by this outbreak find it difficult to finance their daily needs, therefore efforts are needed to increase people's income. One technology that can be applied is the cultivation of fish in tanks with vegetables (aquaponics). The purpose of this activity is to provide knowledge and skills about the cultivation of catfish (Clarias gariepinus) with aquaponics technology of the bucket fish farming system which can ultimately be used as additional income, besides that it is hoped that this activity can be used as an example in updating/information in the field of aquaculture. This socialization activity was carried out in the "Usaha Mandiri" Group of Binawidya Village, Binawidya District, Pekanbaru in June-November 2021. The results achieved in this activity were an increase in the skills knowledge of the training participants, namely the result of evaluating the level of community knowledge about water source technology with the following categories: Do not understand 10% and understand 90%, want to try 60%, the results of observations on the growth of catfish with an average weight of 119,00-127,00 g/indv. and 90% survival rate.

Abstract

Mapping of coastline changes helps in coastal development and monitoring. The city of Dumai, on the east coast of Riau Province, has undergone significant and radical changes caused by the intervention of humans and nature over the past three decades. This study mapped and measured the rate of change of the coastline of Dumai City for 30 years. The Landsat (TM, and OLI) image series, 1990, 1999, 2008, and 2020 became a data source to generate coastlines through on-screen digitization techniques, then to study the temporal behavior of coastlines using the Digital Shoreline Analysis System (DSAS) and geographic information systems to describe the spatial and temporal variations of coastlines. The results showed that the coastline length during the observation ranged from 123,14 to 125,23 km, while the average accretion rate was 1.17 meters per year while the average abrasion rate was 2.04 meters per year. Those rates of change affected coastline expanded to the sea for 60,82 hectares and eroded 760,20 hectares coastline to the land.

Abstract

Togok is a fishing gear in the form of a conical net body whose arms are on two poles and the success of catching it relies on currents, togok fishing gear is used to catch Rebon shrimp (Acetes japonicas) but in its operation, many catches are found bycatch. The high bycatch will have an impact on capture sustainable fisheries, one of the efforts to reduce bycatch is by using BRD (Bycatch Reduction Devices), the use of BRD has been widely carried out on trawl fishing gear but on togok fishing gear, it has never been done. This study aimed for knowing the reduction in catches of main catch, bycatch, and discard the togok fishing gear that has been installed with rope BRD and knows the reduction in catches of shrimp and fish species. This study uses experimental fishing, namely by carrying out direct fishing operations with local fishermen for 20 days of catch. The reduction of togok catch using BRD type rope BRD in the main catch is 8.4%, in bycatch is 11.8% and discard is 17, 1% and the reduction in catch of shrimp species ranged from 8,4% - 13,5% and reduction in catch of fish species ranged from 10,9% - 22,6%.

Abstract

Kapal gillnet termasuk kedalam kategori kapal static gear yang dalam pengoperasiannya lebih mementingkan stabilitas yang baik dan area kerja yang luas daripada kecepatan kapalnya. Rasio dimensi utama dapat menggambarkan karakteristik suatu kapal. Karakteristik tersebut mencakup performance aspek penting diantaranya: stabilitas, olah gerak kapal, tahanan, kemampuan muat dan aspek teknis lainnya yang tergambar dalam nilai rasio dimensi utama. Informasi mengenai karakteristik kapal penangkap ikan perlu diidentifikasi sebab kapal menjadi salah satu faktor penentu keberhasilan nelayan dalam mendapatkan hasil tangkapan. Penelitian ini bertujuan untuk mengidentifikasi karakteristik dimensi utama kapal gillnet udang mantis di Kampung Nelayan, Jambi. Pengumpulan data dilakukan bulan November sampai Desember 2018. Metode yang digunakan adalah survey dengan melakukan pengukuran L, B, dan D secara langsung di lapangan dan melakukan wawancara terhadap nelayan gillnet udang mantis. Hasil penelitian menunjukkan bahwa kapal gillnet udang mantis di lokasi penelitian memiliki dimensi utama hampir sama atau tidak jauh beda. Nilai dimensi utama menunjukkan, L/B berkisar 4,32-6,07, L/D berkisar 5,59-8,70, dan B/D berkisar 1,15-1,55. Nilai-nilai perbandingan tersebut masih berada dalam rentang nilai rasio dimensi utama kapal static gear di Indonesia. Pada nilai B/D perlu mendapat perhatian karena memiliki nilai perbandingan yang kecil yang berpengaruh pada stabilitas kapal menjadi kurang baik. Meski demikian, sejauh ini kapal yang digunakan mampu menunjang pelaksanaan aktivitas penangkapan udang mantis di lokasi penelitian.

Abstract

The findings of research products that have the potential to become entrepreneurial products are SAJAG (magic powder for peat water purification) with variant formulations of CaO+PAC and CaO+Al2(SO4)3+PAC ingredients that have not been produced and patented in the same packaging and brand. The objectives of this service are to: (1) transfer the results of science and technology directly to UMK partners, students/alumni of the University of Riau through the development and production of variants of SAJAG material formulations; (2) fostering the entrepreneurial spirit of students with SAJAG products; (3) produce useful and economically valuable products from research results that have the potential to be marketed by UMK students as entrepreneurial actors; (4) generate student income potential from marketing SAJAG products. The methods of counseling, training and independent practice as well as mentoring are used in implementing the activities to 25 students/alumni who are members of business partners. From the results of this activity, knowledge changes in the target community groups have been obtained and have succeeded in implementing skills by producing a total of 7000 sachets of product for 10L volume of peat water, of which 1500 sachets were successfully sold with a sales value of Rp. 3,750,000. The production process continued until simple patents were obtained for the two variants of SAJAG products to be marketed, managed by the 'BAHARI' group as a new student business partner.
