The test fish used was gourami that amounted to 320 tails with a length of 4-6 cm from Farming Development Gurame and Nilem – Singaparna, Tasikmalaya. The container used in this research was an aquarium with a total of 16 pieces with a size of 40 × 30 × 30 cm<sup>3</sup>. The density of gourami fingerlings during the research was 20 fish-tails/aquarium with long maintenance of 40 days. The feed given is 5% of the fish body biomass. The research was conducted on 8 November 2019 until 14 February 2020 at the Fisheries Laboratory, Faculty of Fisheries and Marine Sciences, Universitas Padjadjaran, Indonesia. This research used experimental method with Completely Random Design (CRD), which consists of four treatments and four times the repeated feeding of commercial feed (control), the leaf meal of lamtoro fermentation result 10%, 15%, and 20%. Based on the results of the research, fermentation of lamtoro leaves can improve nutrient content after fermentation, seen from the presence of increased protein content from 21.88% to 26.11% and decrease in crude fiber content from 46.33% to 20.85%. The addition of lamtoro leaf meal fermentation results up to 15% in commercial feed resulting in a daily growth rate of 1.90%, feed conversion ratio of 2.05 and the survival rate of 70%.</p> Choirun Nissa Ramadhani, Yuli Andriani, Ibnu Bangkit Bioshina Suryadi, Kiki Haetami ##submission.copyrightStatement## https://journalajfar.com/index.php/AJFAR/article/view/30138 Tue, 11 Aug 2020 00:00:00 +0000 Effects of Dietary Potassium Diformate on Growth Performance, the Relationship between Fish Length and Weight, Feed Conversion and Survival Rate of Giant Freshwater Shrimp (Macrobrachium rosenbergii) https://journalajfar.com/index.php/AJFAR/article/view/30139 <p>This study was purposed to determine the optimal dose addition of potassium diformate to commercial feed to increase the growth of giant freshwater shrimp. The method employed in this study was an experimental method, embracing application of a Randomized Block Design (RBD) method. It consists of four treatments and four replications. The treatments was based on the difference of potassium diformate amount in which given to giant freshwater shrimp. The difference of potassium diformate amount was 0% (control), 1%, 3%, and 5%. The sample of study used giant freshwater shrimp with a length of 4 - 6 cm. The samples were obtained from the Giant freshwater Shrimp Breeding Center, Pamarican, West Java Province. The shrimp were kept in 16 nets in a density of 20 shrimps and the size of the net cage is about 1 m<sup>3</sup>. The parameters observed in this research were daily growth rate, feed efficiency, the relation between length and weight, survival rate (analyzed using ANOVA with p &lt; 0,05), and water quality. The sampling was made every 10 days. The results showed that the addition of potassium diformate by 1% gave the best result of daily growth rate of 1.86% ± 0.60, feed efficiency value of 19% ± 1.91, survival rate of 92% with net profit Rp. 67.160.- and for the length and weight relationship has a value of b&gt; 3 which means that it has positive allometry along with water quality parameters regarded to SNI (Indonesian national standard).</p> Anggi Nugraha, .
