Abstract

Abstrak - Serangan penyakit merupakan pemicu kegagalan budidaya. Penyakit yang menyerang organisme budidaya air tawar yaitu penyakit bacterial salah satu agen bakteri yang menginfeksi adalah bakteri P. fluorescens. Penggunaan antibiotik seringkali digunakan untuk mengatasi penyakit yang disebabkan oleh bakteri, sehingga perlu adanya alternatif dengan penggunaan bahan alami. Penelitian ini bertujuan untuk mengetahui pengaruh ekstrak lengkuas merah (A. purpurata) terhadap daya hambat bakteri P. fluorescens secara In Vitro. Penelitian ini menggunakan metode eksperimen dengan Rancangan Acak Lengkap (RAL) yang terdiri dari 5 perlakuan, 2 kontrol dan 4 kali ulangan. Perlakuan A (100 ppm), perlakuan B (105 ppm), perlakuan C (110 ppm), perlakuan D (115 ppm), perlakuan E (120 ppm), kontrol positif menggunakan tetracyline 30 ppm, dan kontrol negatif tanpa pemberian ekstrak. Hasil penelitian didapat zona hambat tertinggi pada perlakuan E (120 ppm) dengan rerata zona hambat sebesar 10,53 mm dan terendah pada perlakuan A (100 ppm) dengan rerata zona hambat sebesar 8,15 mm. Zona hambat antar perlakuan menunjukkan grafik linier dengan persamaan y = -3,25 + 0,11x dan koefisien determinasi (R2) yaitu sebesar 0,8552. Kata kunci: Lengkuas Merah (A. purpurata), P. fluorescens, Antibakteri Abstract - Disease attack is a trigger for cultivation failure. Disease tat attack freshwater aquaculture organisms, namely bacterial disease, one of the bacterial agents that infect are P. fluorescens bacteria. The use of antibiotics is still often used to treat diseases caused by bacteria, so there is a need for alternatives to the use of natural ingredients. This study aims to determine effect of red galangal extract (A. pupurata) on inhibitory of P. fluorescens bacteria in vitro. This study used an experimental method with a completely randomized design (CRD) consisting of 5 treatments, 2 controls and 4 replications. Treatment A (100 ppm), treatment B (105 ppm), treatment C (110 ppm), treatment D (115 ppm), treatment E (120 ppm), positive control with 30 ppm tetracyline, and negative control without extract. The results showed that the highest inhibition zone was in treatment E (120 ppm) with an average inhibition zone of 10,53 mm and the lowest was in treatment A (100 ppm) with an average inhibition zone of 8,15 mm. The inhibition zone between treatments shows a linear graph with the equation y = -3,25 + 0,11x and the coefficient of determination (R2) is 0,8552. Key words: Red galangal (A. purpurata), P. fluorescens, Antibacterial

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.
