Abstract

Water quality can affect the survival and growth of aquatic organisms considering water is a living medium for fish. This study aims to determine how the effect of different models of different ponds on water quality fluctuations for the growth of white shrimp (L. vannamei) intensive pattern. The method used in this study is a comparative descriptive method. The statistical test used is using T test two samples (independent). The main parameters in this study were the results of measuring the growth of white shrimp (L. vannamei) while the supporting parameters in this study were measurements of water quality and total bacteria. The results of this study can be seen that differences in cultivation models have a significant effect on temperature, pH (Power of Hydrogen), DO (Dissolved oxygen), nitrate and have no significant effect on salinity, ammonia and nitrite. The average Specific Growth Rate (SGR) of vaname shrimp in the indoor culture model is 4.5±0.003%/day and the average Growth Rate (GR) is 0.29±0.024 g/day. While the outdoor cultivation model is 3.9±0.003%/day and the average Growth Rate (GR) is 0.26±0.017 g/day.

Abstract

Ikan koi (Cyprinus carpio) adalah salah satu komoditas ikan air tawar yang mempunyai nilai ekonomis tinggi. Adanya serangan penyakit pada budidaya ikan koi seperti Aeromonas hydrophilla dapat menyebabkan kerugian ekonomi dalam budidaya. Banyak upaya yang dilakukan untuk mengobati serangan bakteri A. hydrophilla salah satunya menggunakan fitofarmaka ekstrak kasar daun api-api (Avicennia marina). Penelitian ini bertujuan untuk mengetahui pengaruh penggunaan ekstrak kasar daun api-api (A. marina) serta mengetahui dosis terbaik terhadap histopatologi hati ikan koi yang diinfeksi bakteri A. hydrophilla. Metode penelitian yang digunakan yaitu metode eksperimen dengan Rancangan Acak Lengkap (RAL). Perlakuan dalam penelitian ini adalah sebanyak 4 perlakuan dengan 3 kali ulangan. Perlakuan A (10 ppm), perlakuan B (30 ppm), perlakuan C (50 ppm) dan perlakuan D (70 ppm). Ikan koi (C. carpio) diinfeksi dengan bakteri A. hydrophilla dengan kepadatan 107 sel/ml. Perendaman ekstrak kasar daun api-api (A. marina) dilakukan pada hari pertama setelah penginfeksian bakteri selama 48 jam. Hasil pengamatan histopatologi hati pada ikan koi diperoleh adanya kerusakan berupa kongesti, hemoragi dan nekrosis pada organ hati. Perendaman dengan ekstrak kasar daun api-api (A. marina) menunjukkan hasil yang berpengaruh nyata (P>0,05) hal ini terbukti dari semakin tinggi dosis ekstrak yang digunakan semakin rendah kerusakan pada hati ikan. Oleh karena itu, perendaman ekstrak kasar daun api-api (A. marina) mampu memberikan efek penyembuhan pada ikan koi (C. carpio) yang diinfeksi bakteri A. hydrophilla. Hasil penelitian menunjukkan bahwa hasil terendah didapatkan pada perlakuan A (10 ppm) dan hasil terbaik ada pada perlakuan D (70 ppm).

Abstract

Edwardsielliosis is a disease that commonly infects freshwater fish including catfish (Clarias sp). Edwardsielliosis is caused by Edwardsiella tarda infection and causes mass mortality in catfish farming. Overcoming diseases in freshwater fish can use drugs or antibiotics that are classified as safe and their use is in accordance with government regulations. This study aims to determine the appropriate dosage of Oxytetracycline in catfish infected by E. tarda bacteria through histological analysis. The study design used Completely Randomized Design with 3 treatments, 1 control and 3 replications in each treatment. Catfish used were ± 25 cm in size and the dose of oxytetracycline used were 15, 30, and 45 ppm. The results showed tissue damage edema, vacuolization, necrosis, and haemorhage in fish infected with Edwardsiella tarda bacteria with the lowest damage at 45 ppm of oxytetracycline treatment. The results indicate that oxytetracycline has an effect on muscle histology and recovery of fish health.

Abstract

Bakteri Pseudomonas  fluorescens adalah agen penyakit yang sering dikaitkan dengan penyakit kulit dan sirip. Pengobatan yang biasa dilakukan yaitu dengan pemberian antibiotik, namun penggunaan yang tidak rasional akan menimbulkan terjadinya kekebalan mikroorganisme terhadap antibiotik. Solusi pengobatan yang dapat diberikan yaitu dengan penggunaan bahan alami daun kapuk randu (C. pentandra (L.) Gaertn) yang mengandung bahan aktif sebagai antibakteri. Tujuan dilakukan penelitian ini yaitu untuk mengetahui pengaruh pemberian ekstrak kasar daun kapuk randu (C. pentandra (L.) Gaertn) terhadap bakteri P. fluorescens. Metode yang digunakan pada penelitian ini yaitu metode eksperimen dengan Rancangan Acak Lengkap (RAL) dengan 5 perlakuan, 3 ulangan dan 2 kontrol dengan uji MIC (Minimum Inhibitory Concentration) dan uji cakram. Dosis perlakuan ekstrak kasar daun kapuk randu yaitu 62,5 ppm, 87,5 ppm, 112,5 ppm, 137,5 ppm dan 162,5 ppm. Hubungan yang terbentuk pada setiap perlakuan menujukkan pola regresi linier dengan persamaan y = 5,0868 + 0,0351x  dan koefisien R2= 0,89. Kesimpulan yang didapatkan pada penelitian yaitu penggunaan ekstrak kasar daun kapuk randu (C. pentandra (L.) Gaertn) berpengaruh dalam menghambat pertumbuhan bakteri P. fluorescens, sejalan dengan penambahan dosis zona hambat yang terbentuk semakin tinggi.   Pseudomonas  fluorescens is a disease agent often associated with skin and fin diseases. The usual treatment is by giving antibiotics, but irrational use will lead to the occurrence of microorganism immunity to antibiotics. The treatment solution that can be given is using natural ingredients from kapok leaves (C. pentandra (L.) Gaertn) which contain active ingredients as antibacterial. This study aimed to determine the effect of the crude extract of kapok leaf (C. pentandra (L.) Gaertn) on P. fluorescens bacteria. The method used in this study is the experimental method with a completely randomized design (CRD) with 5 treatments, 3 replications, and 2 controls with the MIC (Minimum Inhibitory Concentration) test and disc test. The treatment doses of kapok leaf crude extract were 62.5 ppm, 87.5 ppm, 112.5 ppm, 137.5 ppm, and 162.5 ppm. The relationship formed in each treatment shows a linear regression pattern with the equation y = 5.0868 + 0.0351x and the coefficient R2=0.89. The conclusion obtained in the study was that the use of the crude extract of kapok leaf (C. pentandra (L.) Gaertn) affected inhibiting the growth of P. fluorescens bacteria, in line with the increase in the dose of inhibition zone formed which was higher.
