The problem that often arises in tilapia cultivation is the low growth of fish caused by the provision of feed that contains high energy but cannot be digested by fish. Utilization of commercial feed as feed for tilapia growth is less effective because the feed is still complex so it requires energy to be broken down into more simple. The method used in this study was a completely randomized design (CRD) which was then analyzed using one way ANOVA variance. The best results were obtained in treatment 4 with an absolute weight value of 2.97, absolute length of 1.19, specific growth rate of 2.75, survival of 83.33% and feed conversion of 0.95%. The conclusion of this study is the treatment of 4 absolute weight of 2.97 g and absolute length of 1.19 cm.

The problem with gouramy cultivation was slow growth due to the short intestines of gouramy so that the absorption of feed takes longer and less. Several previous studies used temulawak in the form of flour, extract, oil which was applied to carp, tilapia, milkfish, catfish. The addition of extract, temulawak flour to the feed gave an increase in growth both in length and weight in the test fish. The purpose of this study was to determine whether or not the effect of temulawak extract on the growth of gouramy fish. This research was conducted for 45 days. This research was conducted by experimental method using a completely randomized design (CRD) with 5 treatments (P) 3 times replication (U), in order to obtain 15 experimental units. Treatment 0 Control (without temulawak extract), Treatment 1 Provision of temulawak extract with a concentration of 14%/kg feed, Treatment P2 Administration of temulawak extract with a concentration of 16%/kg feed, treatment P3 Administration of temulawak extract with a concentration of 18%/kg feed, and treatment P4 administration of temulawak extract with a concentration of 20%/kg feed. The results showed that in the P0 treatment the absolute weight gain was 0.78 grams, in the P1 treatment the absolute weight was 0.58 grams, the P2 treatment was 0.33 grams, the P3 treatment was 0.37 grams, and in the P4 treatment it was obtained The result of absolute weight gain was 0.39 grams. The results showed the absolute length increase ranged from 0.35-0.57 cm. It can be concluded that the addition of temulawak extract to the commercial feed of carp has no significant effect on absolute weight, absolute length, survival rate and feed efficiency level.

Cork fish is one of the commodities from the freshwater fisheries sector which is commonly found in rivers, swamps and swamps that have high economic value and high market demand. The availability of cork fish is still limited to the results of their catch in the wild. And efforts to develop cork fish culture are still small due to slow growth in cork fish and the low response of cork fish to commercially-made feed compared to natural feed. This research is intended to improve the growth of cork fish fed with cinnamon leaf flour (Cinnamomumm burnamani) at different doses.The design used in this study was a completely randomized design (CRD) consisting of 4 treatments with 3 replications. The treatments performed were control (P1), addition of 0.5% cinnamon leaf flour (P2), addition of cinnamon leaf flour 1% (P3), and addition of cinnamon leaf flour 1.5% (P4). The research parameters observed were absolute weight, absolute length, daily growth rate, EP, fat in SR fish body, and cork fish water quality. The results showed that the addition of cinnamon leaf flour at a dose of 1% influenced the growth of absolute weight, absolute length, LPH, and EP. The addition of anis wood leaf flour with a dose of 1.5% can reduce fat content in the body of cork fish.Keywords: Canna striata, Cinnamomum burnamni

Abstract. Cokrowati N, Risjani Y, Firdaus M, Andayani S. 2021. Accelerated growth of Kappaphycus alvarezii using Sargassum aquifolium extract and its anatomical characteristics. Biodiversitas 22: 5195-5202. Cultivation of Kappaphycus alvarezii seaweed has been carried out in Ekas Bay of Jerowaru Sub-district, East Lombok, West Nusa Tenggara, Indonesia but its production has decreased in the last three years due to its slow growth. In 2014, seaweed production was 1,882,875.50 tons and in 2017 it was 1,037,000 tons. Efforts are needed to increase growth by providing growth triggers from marine natural ingredients, namely Sargassum aquifolium. These brown algae can be found in the waters of Ekas Bay, the numbers are abundant and untapped. The purpose of this study was to analyze the growth of K. alvarezii given S. aquifolium extract. This research was conducted in the waters of Ekas Bay. The method used is experimental. The experimental design used was a completely randomized design with different treatments of K. alvarezii soaking time using S. aquifolium extract. The results showed that the growth of K. alvarezii given S. aquifolium extract increased and was significantly different between treatments. The highest absolute weight was 479 g in treatment A (soaking for 2 hours) and the lowest absolute weight was 181.25 g in treatment K (control). The highest growth rate occurred on the 18th day, namely 9.24% and the lowest was in the K treatment (control) which was 1.3%.
