ANALYSIS CORELATION BETWEEN TOTAL ORGANIC MATTER (TOM) WITH ABUNDANCE OF VIBRIO SP. BACTERIA IN INTENSIVE CULTIVATION VANNAMEI SHRIMP (Litopenaeus vannamei)
Full text linkPoor water quality conditions in the cultivation media can cause an increase in pathogenic bacteria such as Vibrio sp. which can inhibit shrimp growth. This study was conducted to analyze the relationship between Total Organic Matter (TOM) and the abundance of Vibrio sp. bacteria in shrimp cultivation media. The stages of the study included checking the abundance of bacteria starting from sterilization of tools, media preparation, bacterial inoculation, bacterial calculations and checking TOM using the titration method. The results showed that TOM in the cultivation media increased as the cultivation period progressed. At the beginning of the distribution, the condition of organic matter in the cultivation media showed a low value and the abundance of Vibrio sp. bacteria in the early stages of cultivation was also low. The highest TOM and abundance of Vibrio sp. bacteria occurred in DOC 91 with a total organic matter of 121.68 ppm and a TVC of 7.29 x 103 CFU/ml. while the lowest TOM and abundance of Vibrio sp. bacteria occurred in DOC 1 with a total organic matter of 88.48 ppm and an abundance of 2.5 x 102 Vibrio sp. CFU/ml. The correlation between TOM and the abundance of Vibrio sp. bacteria in the cultivation media shows a positive linear relationship. This study shows that the high content of organic matter in the cultivation media affects the abundance of Vibrio sp. bacteria in the cultivation media. The higher the organic matter in the cultivation media, the abundance of Vibrio sp. bacteria also increases.Kondisi kualitas air yang buruk pada media budidaya dapat menyebabkan meningkatnya bakteri pathogen Vibrio sp. yang dapat menghambat pertumbuhan udang. Penelitian ini dilakukan bertujuan untuk menganalisis hubungan antara kelimpahan bakteri Vibrio sp. dengan Total Organik Matter (TOM) pada media budidaya udang. Tahapan penelitian meliputi pengecekan kelimpahan bakteri mulai dari sterilisasi alat – alat, persiapan media, inokulasi bakteri, perhitungan bakteri dan pengecekan TOM dengan metode titrasi. Hasil penelitian menunjukkan TOM pada media budidaya mengalami peningkatan seiring berjalannya masa budidaya. Pada awal penebaran, kondisi bahan organik pada media budidaya menunjukkan nilai yang rendah dan kelimpahan bakteri Vibrio sp. pada masa awal budidaya juga rendah. TOM dan kelimpahan bakteri Vibrio sp. tertinggi terjadi pada DOC 91 dengan total bahan organik sebesar 121,68 ppm dan TVC sebesar 7,29 x 103 CFU/ml. sedangkan TOM dan kelimpahan bakteri Vibrio sp. terendah terjadi pada DOC 1 dengan total bahan organik 88,48 ppm dan kelimpahan bakteri Vibrio sp. 2,5 x 102 CFU/ml. Korelasi hubungan antara TOM dengan kelimpahan bakteri Vibrio sp. pada media budidaya menunjukkan hubungan yang linier positif atau berbanding lurus. Dalam penelitian ini menunjukkan tingginya kandungan bahan organik pada media budidaya berpengaruh terhadap kelimpahan bakteri Vibrio sp. pada media budidaya. Semakin tinggi bahan organik yang terdapat pada media budidaya, kelimpahan bakteri Vibrio sp. juga semakin mengalami peningkatan

COMPARISON OF FLOATING NET CAGES CULTIVATION TECHNIQUES IN JATIGEDE RESERVOIR AND JATILUHUR RESERVOIR: REGULATION, MANAGEMENT, CULTIVATION SYSTEM, AND ENVIRONMENTAL IMPACT
Full text linkAquaculture using the Floating Net Cage (FNCs) system has rapidly developed and become an important economic source, but it also poses environmental pressures such as pollution and eutrophication. Jatigede and Jatiluhur Reservoirs serve as examples of water bodies affected by the accumulation of aquaculture waste, despite having different legal statuses and management approaches. This study aims to evaluate the environmental impacts of FNCs aquaculture in both reservoirs and to formulate sustainable management strategies that balance economic and ecological aspects. The findings indicate that FNCs activities are prohibited in Jatigede through local regulations; however, illegal practices persist due to economic reasons, with simple farming systems centered on Nile tilapia. In contrast, Jatiluhur allows FNCs operations under a permit system, but the number of cages has exceeded the environmental carrying capacity, with more intensive farming practices using high levels of supplementary feed. Ecological impacts such as eutrophication occur in both reservoirs, with a more severe scale in Jatiluhur. Sustainable management efforts are urgently needed, including alternative livelihoods, regulation of FNCs numbers, and education on environmentally friendly aquaculture practices.Aquaculture using the Floating Net Cage (FNCs) system has rapidly developed and become an important economic source, but it also poses environmental pressures such as pollution and eutrophication.
