Abstract

Mackerel (Rastrelliger sp.) is a type of marine fish widely consumed. Several factors influencing it include affordable prices, delicious taste, and the ability to be processed into various dishes. However, mackerel fish has a weakness: it quickly declines in quality if not managed properly. In the face of increasing demand, it is crucial to meet the need for fish with an optimal level of freshness. Methods have been used to maintain the freshness of fish, such as salting, freezing, and using plant ingredients. However, the use of natural ingredients from plants often has a low shelf life and can cause a decrease in fish quality. The method used in community service activities in Air Genting village is counselling. Counselling is carried out through the delivery of material, discussions (in the form of questions and answers), and explanations about tools capable of producing ozone. This activity aims to inform the public about technology with the ozone system. This technology can increase the shelf life of mackerel and keep the quality of the fish good and still suitable for consumption.            Keywords: fish; curing; ozone

Abstract

This study aimed to determine the effectiveness of papaya leaf infusion against the weight gain of Nile tilapia infected with Aeromonas hydrophila and identify the active compounds contained therein.This study used a complete randomized design. The treatment consists of 5 treatments: treatment K (control), treatment A (25 ppt), treatment B (50 ppt), treatment C (75 ppt), and treatment D (100 ppt). This research includes several stages, the first being to infect tilapia with A. hydophila. The second stage is to mix papaya leaf infusion into the feed and observe behaviour, clinical symptoms, weight gain, water quality parameters, and phytochemical analysis. Results showed that treatment A showed the highest value for weight gain. Active compounds in papaya leaf infusion are alkaloids, flavonoids, terpenoids/steroids, glycosides, saponins, and tannins. Papaya leaf infusion increased the weight gain of Nile tilapia infected with A. hydrophila.

Abstract

Abstract: Aquaculture has significant potential to contribute to local economic development. However, one of the major challenges faced by fish farmers is that fish fry production remains below target, with productivity below 70%. This low level of production negatively affects farmers' income and the sustainability of their aquaculture operations. One of the hatcheries facing this challenge is the Unit Pembenihan Rakyat Karya Yuda. The application of ozonation technology offers a promising approach to improving water quality and enhancing fish fry production. However, knowledge of how to apply ozonation technology remains limited among fish farmers. This community service program aimed to enhance fish farmers' knowledge and understanding of ozonation technology and its application in aquaculture. The program consisted of three stages: preparation, implementation, and evaluation. The results showed that applying ozone gas to pond water improved catfish fry productivity. The water quality parameters remained within the normal range, with a temperature of 30.2°C, a pH of 7.9, and a dissolved oxygen (DO) concentration of 6.7 mg/L. In addition, the fish egg hatching rate exceeded 85%, the fish fry exhibited faster growth, and no fungal infection was observed on the fish eggs. In conclusion, this community service program demonstrated that the application of ozonation technology benefited UPR Karya Yuda by maintaining good water quality and increasing fish fry production.   Keyword: fish; ozone plasma; pond   Abstrak: Budidaya perikanan memiliki potensi yang besar dalam mendorong peningkatan perekonomian di masyarakat. Kendala yang dihadapi oleh pembudidaya ikan diantaranya produktivitas benih ikan yang masih dibawah target yaitu < 70%. Produksi ikan yang rendah akan berpengaruh terhadap pendapatan pembudidaya ikan. Pembudidaya ikan yang mengalami masalah seperti ini contohnya Unit Pembenihan Rakyat Karya Yuda. Solusi yang dapat dipilih yaitu penggunaan teknologi ozonisasi. Akan tetapi, informasi terkait manfaat teknologi ozonisasi ini masih minim di kalangan pembudidaya ikan. Tujuan kegiatan pengabdian kepada masyarakat yaitu meningkatkan pengetahuan dan informasi kepada pembudidaya ikan terkait teknologi ozonisasi.. Hasil kegiatan yaitu gas ozon yang diaplikasikan pada air kolam mendukung produktivitas benih ikan lele. Parameter kualitas air tergolong normal yaitu suhu sebesar 30,2 0C, nilai pH.nya 7,9 dan nilai DO yaitu 6,7 mg/L. Sedangkan daya tetas telur ikan > 85%, pertumbuhan benih ikan lebih cepat dan tidak ditemukan jamur pada telur ikan. Simpulan dari kegiatan pengabdian kepada masyarakat adalah teknologi ozonisasi memberikan manfaat untuk UPR Karya Yuda, yaitu mempertahankan kualitas air tetap baik bagi ikan serta meningkatkan produksi benih ikan.     Kata kunci: ikan; plasma ozon; kolam
