Abstract

Penelitian ini dilakukan di Desa Cicareuh pada tanggal 04 April - 13 Juni 2022. Pengukuran In situ meliputi temperature (Suhu), derajat keasaman (pH), oksigen (DO) secara langsung ditempat tambak LAT. Pengukuran Ex situ di Laboratorium IPB University meliputi Amonia, Alkalinitas, Nitrit, Nitrat, dan Fosfat. Sistem Vegetable Floting Raft merupakan salah satu fitoremediasi yang menggunakan paduan akuakultur dan media tanam kangkung  memiliki resirkulasi yang bertujuan untuk mengontrol kualitas air. Hasil tujuan diatas menunjukan perbandingan parameter kualitas air dalam sistem Vegetable Floating Raft dan kolam kontrol, untuk mengetahui efektivitas Vegetable Floating Raft dalam senyawa amonia pada hasil budidaya Lobster Air Tawar serta mengetahui korelasi paduan kualitas air dan pertumbuhan LAT dalam sistem VFR. Hasil dari penelitian menunjukan bahwa perlakuan VFR memiliki kualitas yang sama dibandingkan dengan kolam budidaya karena mampu memberikan hasil yang tidak berbeda nyata (P0,05) pada setiap perlakuan.

Abstract

The development of eel fish cultivation has quite good business opportunities and prospects. However, the main obstacle in cultivating eel fish is the high mortality in the glass eel phase, so it has a survival rate of 30-50% and slow growth, namely less than 3.1%. One effort to maximize glass eel maintenance is through optimizing alkalinity as a buffer for water quality. The alkalinity level in the maintenance medium can be regulated by adding calcium carbonate (CaCO3). This research aims to determine the effect of adding CaCO3 to the rearing media on glass eels' growth and survival rate. The study was conducted for 14 days in March 2023. The method was wholly randomized with three replications in 3 treatments (P1=0 mg L-1, P2=50 mg L-1, P3=100 mg L-1). Analysis of research data used the ANOVA test. Adding CaCO3 produced a natural effect on length growth with a value of 0.16 cm, weight growth of 0.73 mg L-1, and a survival rate of 74%. The treatment did not naturally affect the alkalinity levels in the glass eel maintenance media. The best treatment effect was found in P2 (50 mg L-1). These results show that adding CaCO3 to the glass eel-rearing media decreased but did not naturally affect alkalinity levels.
