Abstract

Teluk Benderas Lake is an oxbow lake formed because the Kampar River's flow was cut off. This lake is a habitat for various types of fish. However, information on fish species in the area is still limited. To find out the kinds of fish in Teluk Benderas Lake, a study was conducted in March-May 2023 using the survey method. Fish sampling was performed once a week for two months. The fish were caught using a trawl measuring 150 m long and 4,5 m wide with 1-inch mesh size. Water quality parameters measured were temperature, brightness, depth, pH, DO, and CO2. The results showed that 1.398 fish were caught, consisting of 4 orders, 13 families, 25 genera, and 32 species. Based on the results of water quality measurements, it was concluded that Teluk Benderas Lake can still support fish life in the waters.

Abstract

Budidaya ikan baung semakin berkembang, karena rasa ikan baung yang gurih, lezat dan memiliki protein yang tinggi. Namun, dalam kegiatan budidaya ikan baung terdapat permasalahan pada telur ikan baung yang bersifat adhesive. Sehingga, menyebabkan telur menempel satu dengan yang lain dan menurunkan nilai penetasan. Metode budidaya ikan baung untuk meningkatkan penetasan telur ikan dapat dilakukan dengan perendaman telur ikan baung pada tumbuhan alami. Tumbuhan alami dipilih karena ramah lingkungan, mudah didapat, harga murah, dan memiliki kandungan zat yang sangat bermanfaat. Perendaman telur dengan tumbuhan alami akan menghilangkan daya rekat ikan baung, dan menghasilkan penetasan telur yang lebih banyak. Teknologi ini menghasilkan kelulushidupan larva ikan baung dengan pengamatan sampai larva berumur 14 hari lebih tinggi dibandingkan dengan kelulushidupan larva dari telur tanpa perendaman tumbuhan alami.

Abstract

Pentingnya cacing sutra sebagai pakan alami sangat dibutuhkan karena memiliki kandungan nutrisi tinggi terutama protein yang mendukung pertumbuhan, perpanjangan masa reproduksi, dan pemijahan ikan . Metode budidaya Tubifex sp. mencakup pemilihan sumber air yang bersih, pemeliharaan suhu dan kondisi lingkungan yang optimal, serta pengelolaan pakan dan limbah. Keberhasilan budidaya Tubifex sp. juga bergantung pada pemilihan substrat yang sesuai, seperti tanah liat atau lumpur organik. Dalam budidaya komersial, cacing Tubifex sp. dapat dipelihara dalam wadah berbentuk bak atau wadah berlubang yang dilengkapi dengan aerasi. Teknologi budidaya Tubifex sp. sangat penting dalam memproduksi pakan alami berkualitas tinggi untuk berbagai jenis organisme akuatik. Penelitian ini membahas metode efisien dalam budidaya Tubifex sp., dengan penekanan pada pemilihan sumber air, kondisi optimal, dan pengelolaan limbah. Teknologi ini menghasilkan cacing Tubifex yang kaya nutrisi, cocok untuk meningkatkan pertumbuhan ikan. Budidaya Tubifex yang berkelanjutan dapat mengurangi tekanan terhadap populasi liar, memberikan manfaat baik bagi akuakultur maupun upaya konservasi.

Abstract

Riau Province has many lakes and reservoirs, one of which is the Koto Panjang Hydroelectric Reservoir, Sustainability of the Koto Panjang Hydroelectric Reservoir Unstable water continuity, drought during the dry season and flooding during the rainy season have caused this power plant to be not optimal, one of the ways that can done to overcome complications in certain areas. Koto Panjang Hydroelectric Reservoir Water is that by using the analysis of the Koto Panjang Hydroelectric Reservoir we can arrange steps in managing the maintenance of the Koto Panjang Hydroelectric Reservoir. Sustainability analysis conducted using the RAP-catchment area application on three dimensions, namely ecology, economics and social, the results of the analysis that have been carried out on the ecological dimension address an index of 52.31 which is classified as quite sustainable in the social dimension category 41.98 which is classified as less sustainable. To improve the index of sustainability in the management of water areas, several management directives are needed, namely reforestation or greening of open land related to rivers and conducting training in environmentally friendly agriculture to provide and support the protection of farming communities and communitiesrelated to fire, develop the potential of natural resources such as tourist attractions as alternative livelihoods to increase community income and increase socialization and encourage people in need in hydropower reservoir catchment areas.

Abstract

The magnitude of the potential has led to the emergence of illegal fishing activities that cause losses to the state and surrounding communities. One of the water zones in Indonesia that has potential and is prone to illegal fishing is the Malacca Strait, including the waters of Rokan Hilir Regency. The research aims to formulate illegal fishing control strategies to prevent and stop illegal fishing activities. This research was conducted in Pasir Limau Kapas District, Rokan Hilir Regency, which consists of Panipahan Kepenghuluan, Panipahan Laut Kepenghuluan, and Panipahan Darat Kepenghuluan from March to July 2023. The primary data are obtained directly through observation and interviews, and secondary data is obtained from relevant agencies and institutions. Data analysis uses a quantitative approach to formulating illegal fishing control strategies using SWOT and descriptive analysis methods. The SWOT analysis results of controlling illegal fishing activities is a W-O (Weakness - Opportunities) strategy by considering existing opportunities and minimizing internal problems that become weaknesses. Some strategies that can be formulated include increasing surveillance in Pasir Limau Kapas Waters, increasing socialization of the impacts of illegal fishing and maintaining marine ecosystems, and improving fisheries support facilities in Pasir Limau Kapas District.

Abstract

The snail silvofishery education in Pangkalan Jambi Village aims to equip mangrove management groups in combining mangrove conservation activities with the utilization of its economic value through the cultivation of Cerithidea obtusa snails, in order to create a balance of mangrove ecosystem services to improve the economy of coastal communities. The target group for this education is the “Harapan Bersama” Mangrove Management Group which is one of the fostered groups of PT. Kilang Pertamina Internasional (PT. KPI). The method used is lectures and tutorials as a result of discussions with the CSR team of PT. KPI. The implementation of education begins with the implementation of a pre-test, presentation of materials accompanied by interactive discussions and post-tests. At the end of the activity, a field review was carried out as a candidate for the silvofishery location. The result is that the implementation of this education is very interactive and gets a positive response from the target group who have long struggled to preserve and utilize the mangrove area through several activities, including planting mangrove seedlings and making abrasion prevention tools and producing mangrove products as well as a mangrove educational tourism village. However, this group does not yet know and understand this silvofishery as a form of environmentally friendly mangrove forest preservation and utilization. Post-activity evaluation has proven that this educational activity has increased the understanding of the target group to diversify their activities in the future. The implementation is to practice and assist the snail silvofishery activities in this group

Abstract

Kegiatan pengabdian kepada masyarakat ini bertujuan untuk meningkatkan keterampilan masyarakat Desa Pangkalan Jambi, Kabupaten Bengkalis, dalam mengembangkan branding dan pemasaran produk olahan mangrove melalui platform digital. Produk olahan mangrove, seperti sirup dan camilan berbasis buah mangrove, memiliki potensi besar sebagai komoditas ekonomi, namun kurang dimanfaatkan secara optimal. Masyarakat cenderung memasarkan produk mereka secara konvensional tanpa memperhatikan elemen branding yang dapat meningkatkan daya saing produk. Untuk mengatasi masalah ini, pelatihan branding dan pembuatan website dilakukan sebagai bagian dari upaya memperkenalkan pemasaran digital. Pelatihan mencakup pengenalan konsep logo, desain kemasan, dan tagline, serta pendampingan dalam pembuatan dan pengelolaan website untuk promosi produk. Hasil kegiatan menunjukkan peningkatan keterampilan masyarakat dalam hal branding, yang tercermin dari peningkatan kualitas kemasan dan desain visual produk. Meskipun terdapat kendala teknis dan non-teknis, seperti keterbatasan akses internet dan kurangnya keterampilan digital, kegiatan ini memberikan dampak positif terhadap pertumbuhan ekonomi masyarakat. Keberlanjutan program ini diharapkan dapat memperkuat kapasitas masyarakat dalam memanfaatkan teknologi digital untuk pemasaran produk secara berkelanjutan.
