Abstract

Barriers to cultivation activities are disease attacks, one of which is caused by infection with the bacterium Edwardsiella tarda. Treatment efforts can be made using natural ingredients such as jackfruit (A. heterophyllus) leaves. This study aims to determine the content of antibacterial compounds in the jackfruit (A. heterophyllus) leaves crude extract and their effect on Edwardsiella tarda bacteria in vitro. The inhibition test used disc test with five different concentrations of jackfruit (A. heterophyllus) leaves crude extract with three replications: 75 mg/L, 150 mg/L, 225 mg/L, 300 mg/L and 375 mg/L with a comparison using two types of controls (positive with 5 mg/L chloramphenicol antibiotics and negative with no treatment) using Tryptone Soy Agar (TSA) media and incubated for 2x24 hours. The results of phytochemical screening proved that the jackfruit (A. heterophyllus) leaves crude extract contains flavonoids, alkaloids, tannins and saponins. Treatment E with a dose of 375 mg/L gave the highest inhibition of 7.80 mm and treatment A with a dose of 75 mg/L gave the lowest inhibition of 4.38 mm.  The relationship between the treatment given to the test parameter in the form of the resulting inhibitory power obtained the equation y = 0.0111x + 3.6297 with an R2 value of 0.974 which means 97% of the treatment given in the form of crude extract of jackfruit (A. heterophyllus) leaves affects inhibition of bacteria E. tarda.

Abstract

Cultivation activities often experience obstacles due to bacterial disease attacks, one of which is caused by P. fluorescens bacteria. Commercial treatment efforts include the use of antibiotics, but this can cause bacterial resistance. Therefore, an alternative treatment that is more environmentally friendly but can still be used as medicine is needed, namely the use of natural ingredients such as jackfruit (A. heterophyllus) leaves. This study aims to determine the effect of crude jackfruit (A. heterophyllus) leaf extract on P. fluorescens bacteria in vitro. This study used an experimental method with a Completely Randomized Design (CRD) consisting of 5 treatments, 2 controls, and 3 replications. The control treatment consisted of a positive control (Tetracycline 30 ppm), and a negative control (only using disc paper), as well as 5 different extract dose treatments, namely treatment A (60 ppm), treatment B (120 ppm), treatment C (180 ppm), treatment D (240 ppm) and treatment E (300 ppm). The results of the study showed that the use of crude jackfruit (A. heterophyllus) leaf extract affected P. fluorescens bacteria. The relationship between the use of crude jackfruit (A. heterophyllus) leaf extract with different doses and the resulting inhibition zone showed a quadratic regression pattern with the equation y = -0.0001x2 + 0.05x + 6.327.

Abstract

Abstrak - Mikroplastik sebagai bentuk pencemaran plastik di perairan yang bersifat persisten dan berpotensi menimbulkan dampak negatif terhadap organisme akuatik. Mikroplastik dalam akuakultur masuk ke tubuh ikan melalui air dan pakan, dengan pakan sebagai jalur paparan utama karena dikonsumsi secara langsung dan berulang. Keberadaan mikroplastik dalam saluran pencernaan ikan dapat menyebabkan gangguan fisiologis dan menurunkan efisiensi penyerapan nutrient serta berpengaruh langsung terhadap pertumbuhan. Ikan lele (Clarias sp.) sebagai komoditas air tawar penting di Indonesia dengan nilai ekonomi tinggi, sehingga dampak mikroplastik terhadap pertumbuhannya perlu dikaji. Penelitian ini bertujuan untuk menganalisis pengaruh pemberian pakan yang mengandung mikroplastik pada dosis berbeda terhadap pertumbuhan ikan lele. Parameter yang diamati meliputi pertambahan bobot, laju pertumbuhan spesifik (Specific Growth Rate; SGR), dan rasio konversi pakan (Feed Conversion Ratio; FCR). Hasil penelitian menunjukkan bahwa perlakuan tanpa mikroplastik menghasilkan bobot akhir dan nilai Specific Growth Rate (SGR) tertinggi, sedangkan peningkatan dosis mikroplastik diikuti oleh penurunan nilai SGR. Kata kunci: Mikroplastik, pakan, pertumbuhan, SGR, FCR, Clarias sp. Abstract - Microplastics are a persistent form of plastic pollution in waters and have the potential to negatively impact aquatic organisms. Microplastics in aquaculture enter fish through water and feed, with feed being the primary route of exposure due to direct and repeated consumption. The presence of microplastics in the digestive tract of fish can cause physiological disorders, reduce nutrient absorption efficiency, and directly affect growth. Catfish (Clarias sp.) are an important freshwater commodity in Indonesia with high economic value, so the impact of microplastics on their growth needs to be studied. This study aims to analyze the effect of feeding feed containing microplastics at different doses on catfish growth. The parameters observed included weight gain, specific growth rate (SGR), and feed conversion ratio (FCR). The results showed that the treatment without microplastics yielded the highest final weight and Specific Growth Rate (SGR) values, whereas increasing the microplastic dose was associated with a decrease in SGR. Keywords : Microplastic, feed, growth, SGR, FCR, Clarias sp.
