Abstract

Rumput laut merupakan salah satu komoditas perikanan yang potensial untuk dibudidayakan. Salah satu rumput laut yang memiliki nilai ekonomis tinggi adalah Eucheuma cottoniiyang merupakanhasil kultur jaringanspesies alga merah penghasil karagenan dan memiliki banyak peranan penting bagi manusia..Penelitian ini bertujuan untuk mengetahui pengaruh penambahan pupuk Cair, NPK, Urea dan TSP dengan doses 100 gram terhadap laju pertumbuhan rumput lautEucheuma cottonii. Penelitian ini dilaksanakan pada bulan Maret- April 2019 dibalai laut Lombok Sekotong Kabupaten Lombok Barat.Metode yang di gunakan adalah RAL (Rancangan Acak Lengkap) dengan 4 perlakuan dan 3 kali ulangan. Media pemeliharaan menggunakan air laut yang ditambahkan pupuk dengan dosis 100 gram, yaitu : P1 (Pupuk Cair), P2 (Pupuk NPK), P3 (Pupuk Urea) P4 (Pupuk TSP). Data yang diamati berupa Berat mutlak, Panjang mutlak, Pertumbuhan harian, Berat relatif, Panjang relatif dan kualitas air yang digunakan sebagai media pemeliharaan. Analisis data menggunakan ANOVA.Hasil penelitian menunjukkan bahwa penambahan Pupuk Cair, NPK, Urea dan TSP dengan doses 100 gram memberikan pengaruh berbeda sangat nyata terhadap pertumbuhan dan kelangsungan Hidup Rumput laut Eucheuma cottonii. Laju pertumbuhan tertinggi pada Pupuk Urea sedangkan pertumbuhan terendah pada Pupuk TSP.

Abstract

In shrimp cultivation, high production activities can cause serious water quality problems. One way that can be done is by transferring cultivation containers with a method of decreasing salinity to 0 ppt with the addition of calcium (CaCO3) as a user balancing the life of cultivated shrimp in order to survive. The purpose of the study was to analyze the survival rate and growth of vaname shrimp (Litopanaeus vannamei) maintained at salinity 0 ppt with multilevel acclimatization method using lime (CaCo3). This study consisted of five treatments, and each treatment had 3 repeats. Thus in this study there were 15 experimental units. As treatment is the difference in acclimatization period decreases salinity as follows: Treatment 1: No decrease in salinity (30 ppt). Treatment 2: Acclimatization for 2 days (30 ppt, 0 ppt) using calcium. Treatment 3: Acclimatization for 3 days (30 ppt, 15 ppt, 0 ppt) using calcium. Treatment 4: Acclimatization for 4 days (30 ppt, 20 ppt, 10 ppt, 0 ppt) using calcium. Treatment 5: Acclimatization for 5 days (30 ppt, 23 ppt, 15 ppt, 8 ppt, 0 ppt) using calcium. The results showed that shrimp acclimatized with tiered use of lime (CaCO3) resulted in absolute weight growth which is a range of 0.45-0.72 grams, absolute long growth which is a range of 3.03-3.81 cm, FCR values that are 0.89-1.85 and survival rates that are 74.67-100%. The conclusion of this study is that the decrease in salinity with the stratified acclimatization method using lime (CaCO3) had no real effect on absolute weight growth, absolute length growth, feed conversion rate, survival rate.
