Abstract

Komunitas perifiton sungai telah merespons kondisi lingkungan. Mereka berguna dalam menggambarkan keadaan ekologis, kinerja, dan keberlanjutan ekosistem karena kemampuan untuk mengukur berbagai parameter lingkungan dan menghubungkannya dengan keanekaragaman, kemerataan, dan kekayaan. Studi ini menyelidiki keanekaragaman perifiton Sungai Bango di Malang dan karenanya menghasilkan daftar periksa kekayaan perifiton sungai, terutama perifiton epilitik. Pengambilan sampel perifiton dan identifikasi dilakukan di Laboratorium Hidrobiologi Fakultas Perikanan dan Ilmu Kelautan Universitas Brawijaya Malang. Penelitian ini dilakukan seminggu sekali dalam sebulan (Mei 2020) antara jam 9 dan 13 (GMT + 7). Identifikasi dan sampel Perifiton dikumpulkan dengan cara mengikis substrat (batuan/batuan) di dalam dan di sekitar titik pengambilan sampel air masing-masing. Hasil penelitian menunjukkan kelimpahan total perifiton berkisar antara 938.900 Ind/mm2 sampai dengan 1.598.125 Ind/mm2 dengan 30 genera yang ditemukan. Kami berasumsi bahwa titik sampling 1 sampai 3 memiliki indeks keanekaragaman sedang; Sebaran jumlah individu tiap spesies tergolong sedang; stabilitas komunitas sedang dan organisme akuatik dapat mentolerir kondisi lingkungan. Namun, titik pengambilan sampel 4 memiliki keragaman yang rendah; sebaran jumlah masing-masing spesies rendah; stabilitas komunitasnya rendah dan hanya dapat ditoleransi oleh organisme akuatik tertentu.

Abstract

The development of the fisheries sector has a significant contribution in improving the economy, especially in Indonesia, which has great potential but has not been utilized optimally. In Tawangargo Village, Malang Regency, training and assistance was carried out for alternative feed formulations for Dumbo catfish (Clarias sp.). This activity aims to empower the community by increasing skills and knowledge in cultivating freshwater fish. The methods used include a community approach, outreach through seminars and direct practice, as well as assistance in alternative feed formulation. The activity stages include initial surveys, outreach and training, which were responded positively by the local community and youth. The cultivation medium is made from a mixture of chicken and cow manure, EM4, molasses and fermented water, then dried in the sun and sprayed with EM4 again before use. Fermented feed is made from cow dung, tofu dregs, corn and rice bran, pellets, EM4, molasses, tape yeast, vitamin C, and water which is fermented for 7 days. The results of the activity show that catfish farming business actors in Tawangargo Village can formulate alternative feed with low costs, easy methods, and efficient results, thereby reducing losses. This training also increases the community's knowledge and ability to make maximum use of land for cultivating freshwater fish, supporting the sustainability of the local economy

Abstract

Pesticides are widely applied in the agriculture sector to protect crops and pest control. The poisonous substance of pesticides will affect all of the organisms, either target and non-target organisms. Fish can play the role of an indicator of genotoxic presence in aquatic environments. Polysaccharide extracts from sargassum have promising anti-genotoxic potential. This study aimed to analyze the anti-genotoxic activity of brown seaweed (Sargassum polycystum) methanol extract against erythrocyte and micronuclei of tilapia exposed by methomyl-base pesticide. Brown seaweed (Sargassum sp.) purchased from farmers in Sumenep Regency, Madura, East Java, then macerated using methanol 1: 3 (w / v) for 3x24 hours at room temperature. The phytochemical screening was including flavonoids, alkaloids, triterpenes, saponins, and tannins. Tilapia fish (TL ± 9-12cm) purchased from the Technical Application Unit of Freshwater Fish (UPT Perikanan Air Tawar), Sumberpasir, Malang, East Java. The result of this study showed that exposure of methomyl-based pesticides in the concentration of 4.015 ppm indicates the formation of micronuclei of 318.33 ‰. The increased concentration of extract treatment is directly proportional to the decrease of micronuclei. It means that sargassum extract can reduce the genotoxic effect on exposed tilapia by methomyl-based pesticides. The best concentration of Sargassum sp. extract that can reduce genotoxic was D (200 ppm). Keywords: Antigenotoxic, Extract, Methomyl, Pesticides, Sargassum sp., Tilapia.

Abstract

This research investigates the phytochemical composition, antioxidant activity, and antibacterial efficacy of Ipomoea pes-caprae extracts collected from Pantai Talang Siring Pamekasan, Madura. Phytochemical analysis revealed the presence of alkaloids, flavonoids, phenolic compounds, terpenoids, tannins, and saponins in the extracts, indicating their rich bioactive profile. Antioxidant activity assessed via the DPPH assay demonstrated concentration-dependent scavenging of free radicals, with methanol and ethanol extracts exhibiting superior activity compared to the aqueous extract. Antibacterial assays against Escherichia coli and Staphylococcus aureus revealed significant inhibitory effects, with methanol and ethanol extracts displaying greater potency than the aqueous extract. These findings underscore the potential of Ipomoea pes-caprae as a source of natural antioxidants and antimicrobial agents, warranting further investigation into its pharmacological applications and therapeutic potential.
