Ritonga, Putri Sasmitha and Dr. Ir. Mohamad Fadjar,, M.Sc. and Ir Ellana Sanoesi,, MP. (2023) Kelimpahan Bakteri Lactobacillus sp. pada Intestine Udang Vaname (Litopenaeus vannamei) yang di Budidaya dengan Padat Tebar Berbeda pada Kolam Indoor. Sarjana thesis, Universitas Brawijaya.
Abstract
Potensi udang vaname (Litopenaeus vannamei) dikhawatirkan menurun akibat adanya penyakit yang menyerang pada udang. Pemberian probiotik Lactobacillus sp. merupakan salah satu solusi agar udang dapat bertahan dari serangan penyakit. Tujuan dari penelitian ini adalah untuk menganalisis kelimpahan Lactobacillus sp. pada intestine udang vaname (L. vannamei) setelah dilakukan pemberian probiotik dan menganalisis pengaruh perbedaan padat tebar terhadap kelimpahan Lactobacillus sp. pada intestine udang vaname (L. vannamei). Penelitian ini dilaksanakan di Instalasi Budidaya Laut (IBL) Prigi dan di UPT Laboratorium Kesehatan Ikan dan Lingkungan Bangil, Jawa Timur pada bulan Januari – April 2023. Metode penelitian yang digunakan yaitu metode deskriptif naratif. Data yang telah diperoleh kemudian dilakukan analisis dengan menggunakan metode deskriptif naratif. Penelitian ini dimulai dari persiapan pemeliharaan udang vaname pada tiga kolam padat tebar berbeda, pemeliharaan udang dan pemberian probiotik, pembuatan media kultur, penanaman media, penghitungan koloni bakteri, dan analisis data. Hasil yang didapatkan bahwa kelimpahan Lactobacillus sp. pada intestine udang vaname untuk hari ke-30 yang terbanyak ada di kolam B dengan jumlah kelimpahan bakteri sebanyak 1,41 x 104 CFU/mL, sedangkan untuk di hari ke-60 kelimpahan terbanyak berada di kolam C dengan kelimpahan bakteri sebanyak 1,2 x 105 CFU/mL. Sedangkan untuk selisih terbanyak antara kelimpahan bakteri pada hari ke-30 dan ke-60 ada di kolam C dengan nilai selisih sebesar 11,45 x 104 CFU/mL, selisih terkecil ada pada kolam B dengan nilai selisih kelimpahan sebanyak 0,02 x 104 CFU/mL. Selain itu, perbedaan padat tebar budidaya udang vaname tidak secara langsung mempengaruhi kelimpahan bakteri Lactobacillus di intestine udang vaname.
English Abstract
The potential for vannamei shrimp (Litopenaeus vannamei) is feared to decrease due to a disease that attacks the shrimp. Giving probiotics Lactobacillus sp. is one of the solutions so that shrimp can survive disease attacks. The purpose of this study was to analyze the abundance of Lactobacillus sp. in the intestine of vannamei shrimp (L. vannamei) after administration of probiotics and analyzing the effect of differences in stocking density on the abundance of Lactobacillus sp. in the intestine of vannamei shrimp (L. vannamei). This research was carried out at the Prigi Marine Cultivation Installation (IBL) and at UPT Fish Health and Environmental Laboratory Bangil, East Java in January - April 2023. The research method used is descriptive narrative method. The data that has been obtained is then analyzed using a descriptive narrative method. This research started with the preparation of vannamei shrimp rearing in three ponds with different stocking densities, shrimp rearing and probiotic administration, culture media preparation, media planting, bacterial colony counting, and data analysis. The results obtained that the abundance of Lactobacillus sp. in vannamei shrimp intestine for the 30th day the highest abundance was in pool B with an abundance of bacteria of 1.41 x 104 CFU/mL, while for the 60th day the highest abundance was in pool C with an abundance of bacteria of 1.2 x 105 CFU/mL. Whereas the largest difference between the abundance of bacteria on the 30th and 60th days is in pool C with a difference value of 11.45 x 104 CFU/mL, the smallest difference is in pool B with a difference in abundance value of 0.02 x 104 CFU /mL. In addition, differences in the stocking density of vaname shrimp did not directly affect the abundance of Lactobacillus bacteria in the intestine of vannamei shrimp.
