YASSAR ARIQ PRADIAN. Perbaikan Kualitas Air dan Pertumbuhan Udang Litopenaeus vannamei dengan Metode Pengapuran. Dibimbing oleh AMALIA PUTRI FIRDAUSI dan IVANA OKTARINA SOPACUA. Vaname merupakan salah satu jenis udang yang sering dibudidayakan. Salah satunya karena udang vaname ini lebih tahan terhadap penyakit dibanding udang putih lainnya dan mempunyai toleransi yang lebar terhadap kondisi lingkungan. Udang vaname berkontribusi cukup besar bagi ekonomi perikanan nasional. Tugas akhir ini bertujuan untuk melakukan dan menganalisis aplikasi kapur dan metode pengapuran terhadap parameter kualitas air dan pertumbuhan dalam pemeliharaan udang vaname Litopenaeus vannamei di Tambak, Dewi Laut Aquaculture, Garut. Lokasi dipilih karena perusahaan menerapkan teknologi yang modern, riset yang terus dikembangkan, serta mempunyai visi misi untuk menciptakan solusi inovatif dan berkelanjutan dalam industri budidaya udang. Metode pemberian kapur dilakukan dengan cara perendaman kapur selama 12 jam sebelum kemudian ditebar dalam wadah budidaya. Parameter yang diukur meliputi parameter kualitas air dan pertumbuhan. Parameter kualitas air mencakup parameter fisika seperti suhu, parameter kimia yang meliputi pH, dissolved oxygen (DO), total ammonia nitrogen (TAN), total alkalinitas, dan total organic matter (TOM), serta parameter biologi yang meliputi total bacteria count (TBC), total vibrio count (TVC), dan total fitoplankton. Nilai parameter masih dibawah standar baku mutu dimana nilai suhu terendah di angka 24?, fluktuasi pH lebih dari 1, nilai DO terendah di angka 3 ppm, nilai TOM terendah di angka 80, nilai alkalinitas tertinggi 269 ppm, nilai TAN tertinggi di angka 2,6 ppm, dan persentase nilai TBC dan TVC tertinggi di angka 25%. Oleh karena itu dapat disimpulkan metode pemberian kapur dengan cara perendaman selama 12 jam tidak efektif.

YASSAR ARIQ PRADIAN. Improving Water Quality and Growth of Litopenaeus vannamei Shrimp through Liming. Supervised by AMALIA PUTRI FIRDAUSI and IVANA OKTARINA SOPACUA. Vaname shrimp is one of the most commonly cultured shrimp species. This is primarily because vaname shrimp are more resistant to diseases compared to other white shrimp species and have a wide tolerance for environmental conditions. Vaname shrimp contribute significantly to the national fisheries economy. This final project aims to conduct and analyze the application of lime and liming methods on water quality parameters and growth in the cultivation of Litopenaeus vannamei vaname shrimp at the Dewi Laut Aquaculture Farm in Garut. The location was chosen because the company implements modern technology, conducts ongoing research, and has a vision and mission to create innovative and sustainable solutions in the shrimp farming industry. The method of applying lime was done by soaking the lime for 12 hours before it was then spread in the culture container. The parameters measured included water quality parameters and growth. Water quality parameters include physical parameters such as temperature, chemical parameters including pH, dissolved oxygen (DO), total ammonia nitrogen (TAN), total alkalinity, and total organic matter (TOM), and biological parameters including total bacteria count (TBC), total vibrio count (TVC), and total phytoplankton. The parameter values were still below the standard quality criteria where the lowest temperature value was 24?, pH fluctuation was more than 1, the lowest DO value was 3 ppm, the lowest TOM value was 80, the highest alkalinity value was 269 ppm, the highest TAN value was 2.6 ppm, and the highest percentage of TBC and TVC values was 25%. Therefore, it can be concluded that the method of applying lime by soaking for 12 hours is not effective.
